What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It isn’t the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigation, how to discover information, is important to everyone. The scientist, however, goes one step further; he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one tim
e must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration(实证) must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at the theory through mathematics. The accuracy(正确性) of his mathematics was later tested through investigation. Einstein’s
ideas were proved to be correct. A scientist uses
many to
ols for measurements. Then the measurements are used to make mathematical calculations(计算) that may test his investigations What makes a scientist according to the passage?
| A．The tools he uses. | B．His ways of learning |
| C．The way he uses his tools | D．The various tools he uses |
“…knowing how to investigation, how to discover information, is important to everyone.”
The writer says this to show ___________.
| A．the importance of information |
| B．the difference between scientists and ordinary people. |
| C．the importance of thinking |
| D．the difference between carpenters and ordinary people |
A sound scientific theory should be one that _________.
| A．works under one set of conditions at one time and also works under the same conditions at other times |
| B．doesn’t allow any change even under different conditions |
| C．Can be used many times under different conditions |
| D．Can be used for many purposes |
What is the main idea of the passage?
| A．Scientists are different from ordinary people. |
| B．The Theory of Relativity. |
| C．Exactness is the core (核心) of science. |
| D．Exactness and way of using tools are the keys to making of a scientist. |
Most of us use the telephone several times a day to talk with friends or make social arrangements(安排). These calls are usually quite easy and require little planning.
Using the telephone for business purpose is different. In any organization the person on the telephone represents the company and gives an impression of the firm to the outside world.
If you want to ensure good public relations, you need to master effective telephone techniques.
You should try to give an impression of an efficient, friendly, progressive company eager to give good service.
Before calling
Choose the right time. Consider the cost, urgency and convenience. When calling overseas, you need to consider the time difference.
Check the number. A great deal of money is wasted each year on dialing wrong numbers.
Plan your call. Make a list of points and questions to be raised.
Be prepared. Gather any files, papers or information that may be needed during the call. It is unprofessional to have to say “Hold on while I look for that.”
If y
ou have to ask a caller to hold on, keep going back and assuring him/her that you will be as quick as possible.
Avoid interruptions. Call at a time when you are unlikely to be distracted(分心).
During the call
Be courteous, polite. Make time for suitable greetings like “How are you today, Jim?” and “Did you enjoy your holiday”?
Put a smile in your voice. Remember, your caller can not see you, so use intonation to good effect and try to sound confident, decisive, helpful, and interested.
Check your notes. Look back at your notes to ensure that you have covered everything and quote figures and other data correctly.
Get feedback. Make sure the caller understands the message correctly, especially deadlines and actions that are involved.
Be courteous. Finish by thanking the caller for his or her time and trouble.
After the call
Make notes. Let it become a habit to make notes of the call and place them in an appropriate file.
Take actions. If you need to send a letter of confirmation or inform someone in your organization about any details of the call, do it immediately so that you do not forget important points. Before calling, you have to _____.
| A．stay at your company only | B．learn important data and figures by heart |
| C．get things ready for the communication | D．choose the right time and place |
During the call, it is unsuitable to _____.
| A．be decisive | B．be heard in low spirits | C．check your notes | D．get feedback |
What does the underlined word “courteous” in the passage mean?
| A．Polite. | B．Active. | C．Effective. | D．Correct. |
What does “getting along” with your teacher mean? “Getting along” means that both you and your teacher have a way of communicating and getting what you need from the relationship. In your teacher’s opinion, he or she wants to make sure that you are paying attention, being polite, and trying your best to learn. In your opinion, you want a teacher who is respectful to you, answers your questions, and tries to help you learn. You can get along and learn without being friends with your teacher, although it’s nice if that happens.
In every school, kids will say that some teachers are mean or strict, but don’t judge a teacher until you are in his or her class and can see for yourself. A strict teacher may be someone who feels strong about getting his or her job done — teaching you the subject you are supposed to learn. It’s also important to remember that making mistakes is a part of learning. By pointing out your mistakes and helping you correct them, a teacher is teaching you. Remember, in most cases, your teacher is on your side.
Even if a teacher isn’t your favorite, you can still have a successful relationship, especially if you carry out your responsibilities as a student. Here are some of those responsibilities:
●Attend class ready to learn. Be prepared for class with the right pencils and books.
●Listen carefully when your teacher is talking.
●Do your best, whether it’s classroom work, homework, or a test.The main idea of this passage is about _______.
| A．learning from your teacher |
| B．making friends with your teacher |
| C．getting along with your teacher |
| D．understanding your teacher |
If you get along with your teacher, _______.
| A．your teacher will have to answer your questions |
| B．both of you will benefit from the relationship |
| C．your teacher will have to be respectful to you |
| D．you will have to try your best to learn |
What does the underlined sentence in the second paragraph mean?
| A．Your teacher is teaching you to learn the subjects. |
| B．The teacher has the responsibility to be strict with students. |
| C．Pointing out your mistakes is also a way for a teacher to teach. |
| D．The teacher is there to help you. |
According to the passage, which of the following is NOT the responsibility of a student?
| A．Learning by making mistakes. | B．Attending class ready to learn. |
| C．Listening to your teacher carefully. | D．Trying your best to learn. |
Boeing said Wednesday that it was entering the space tourism business, an announcement that could bolster（增强）the Obama administration’s efforts to transform the National Aeronautics and Space Administration into an agency that focuses less on building rockets and more on nurturing a commercial space industry.
The flights, which could begin as early as 2015, would most likely launch from Cape Canaveral in Florida to the International Space Station. The Obama administration has proposed turning over to private companies the business of taking NASA astronauts to orbit, and Boeing and Bigelow Aerospace of Las Vegas won an $18 million contract this year for preliminary (初步的)development and testing of a capsule that could carry seven passengers.
Current NASA plans call for four space station crew members to go up at a time, which would leave up to three seats available for space tourists. The flights would be the first to give nonprofessional astronauts the chance to go into orbit aboard a spacecraft launched from the United States. Seven earlier space tourists have made visits to the space station, riding in Russian Soyuz capsules.
“We’re ready now to start talking to possible customers,” said Eric C. Anderson, co-founder and chairman of Space Adventures, the space tourism company based in Virginia that would market the seats for Boeing.
Boeing and Space Adventures have not set a price, although Mr. Anderson said it would be competitive with the Soyuz flights, which Space Adventures arranged with the Russian Space Agency. Guy Laliberté, founder of Cirque du Soleil, paid about $40 million for a Soyuz ride and an eight-day stay at the space station last year. But the possibilities that anyone buying a ticket will get to space on an American vehicle depend on discussions in Congress about the future of NASA. Which of the following is most probably a private travel company?
A. Boeing. B. Space Adventure.
C. NASA. D. Russian Space Agency. How many people can be carried along on a capsule to the space station?
| A．3. | B．4. | C．7. | D．11. |
What can be inferred from the passage?
| A．The American space tourism company is located in Virginia. |
| B．Russia has already taken lead in working on the space tourism business. |
| C．NASA has decided to focus less on building rockets because of the financial crisis. |
| D．In 2015, America would be the first country in the world to run the space tourism business. |
What’s the best title of the passage?
| A．Taking NASA Astronauts to Orbit. | B．Living in the Space Station Space. |
| C．Ticket Price under Discussion. | D．Boeing Could Fly You to Orbit by 2015. |
What is art? According to one definition, it is the creation of something that appeals to our sense of beauty. This definition may include painting, drawing, sculpture, and architecture, or performing arts such as music and drama. Cultural and historical influences, as well as one’s own consciousness of what is aesthetically(审美地 )pleasing, play a role in what one believes to be art. To some people, art is the description of an object--- a painting or sculpture of a person, for example. For others, art may be a blank canvas, or a piece of chalk.
In order to talk about the different artistic styles that have existed over time, art historians have classified these styles into different periods and organized them in chronological order. The works of art produced within each period mirror the culture and events of that time.
The earliest forms of art, from the prehistoric era(时代), include simple cave paintings and figures made from stone. These were followed by the sculptures and carvings of Ancient Civilizations era. Styles of the later Classical era (800 B.C. to 200 A.D.), reflect the culture of the time--- one that favored simplicity and balance. The period of the Middle Ages followed, and was succeeded by a revival（复兴） of classical styles in the Renaissance era, beginning around 1400. Well-known artists of this time include Michelangelo and da Vinci. One hundred years of Baroque style, and then fifty years of Rococo followed the 200-year Renaissance. The start of the nineteenth century saw the rise of the Premodern era, followed by the Modern era, a period that lasted until 1945. This was followed by Postmodern era that characterizes the present day.
In addition to differences in artistic styles between eras, there are also differences within each era. The Postmodern era, for example, has featured innovative（创新） artistic styles such as Pop Art ( which includes work by Andy Warhol), Minimalism, and Conceptualism. Since the 1960s, Conceptualism has grown in popularity. This style focuses more on the idea or ‘concept’ of art using realistic objects, rather than on art that is created using traditional materials such as paint, canvas, stone, or clay. Whereas Warhol used a can of beans as the basis for a painting, for example, a conceptual artist might say that the can itself is a work of art.
Conceptualism has become an increasingly controversial（有争议的） art style, particularly as result of numerous conceptual artists winning the Turner Prize. This ￡20,000 award is presented annually to a British artist under the age of fifty, in recognition of an outstanding work. Sponsored by the Tate Gallery of Britain, it is recognized as one of Europe’s most prestigious awards for visual arts. Its aim is to promote discussion about contemporary British art. In 2002, pop music icon Madonna presented the Turner Prize to conceptual artist Martin Creed. One of the artistic styles that many people today discuss and arguing about is ______.
| A．classic style | B．Conceptualism | C．Pop art | D．Baroque style |
Which statement is NOT true according to the passage?
| A．Pop Art, Minimalism and Conceptualism are styles that developed in the Postmodern era. |
| B．Some of the world’s earliest art was created in caves. |
| C．History, culture and one’s concept of beauty affect what a person believes to be art. |
| D．Art historians refer to today’s artistic period as the Modern era. |
According to the passage, art historians have classified these styles into ____ periods.
| A．7 | B．8 | C．10 | D．12 |
If the passage continues, the following paragraph will be probably about_________.
| A．Martin Creed’s winning works | B．Madonna’s outstanding art style |
| C．the status of Conceptualism | D．the conclusion of art |
We can make mistakes at any age．Some mistakes we make are about money．But most mistakes are about people．One might say, "Did Jerry really care when I broke up with Helen?" "When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?" When we look back, doubts like these can make us feel bad．
Why do we go wrong about our friends? Sometimes what people want to say hides their real meaning．And if we don't really listen, we miss the feeling behind the words． Suppose someone tells you, "You're a lucky dog．" Is he really on your side? If he says, "You are a lucky guy", that's being friendly．But if he says "a lucky dog", there's a bit of envy in those words．Maybe he doesn't see it himself．But he puts you down a little if he brings in the "dog"．What he may be saying is that he doesn't think you deserve your luck．
"Just think of all the things you have to be thankful for" is another noise that says one thing and means another．It could mean that the speaker i
s tryin
g to get you to see your problem as part of your life as a whole．But is he trying to? Wrapped up in this phrase is the thought that your problem isn't important．It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night．
How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking．Do his words fit the way he looks? Does what he says agree with the tone of voice, his posture, or the look in his eyes? Stop and think．The minute you spend thinking about the real meaning of what people say to you may save another mistake．
Therefore, when you hear someone saying, 
please try to know what he really means．Don't just listen to what he says with your ears but feel the words he uses with your head．In this way you may m
ake fewer mistakes．.

Dear Michelle:
My Dad hates my Mom. He tells me that she is a liar and that I should not trust her. Of course, they are divorced but they have “joint custody(共同监护)”. What a joke! I am 15, my brother is nine, and we have a life of hell, frankly.
We live one week on and one week off. This was the brilliant idea of both of my parents, which was fair to them but ruining my life. I can’t get away from his voice and his putting my mom down. Sometimes I think about running away.
A Hopeless Ant
Dear Hopeless Ant:
First, thank you for trusting me with your problem. If all you said is correct, then there are several
things that you can and should do to help yourself, your brother, and your parents.
● You need a family counselor(顾问). Such a person could listen to each family member alone and
then meet together to talk about the situation.
If refused, you need to talk to a counselor in your school. You need to be heard, and you need an
adult who will listen. A school counselor can organize a meeting with your parents.
● Perhaps you need to write to her. Writing things down allows people to go over it more than one
time.
I cannot imagine that she will stand passively by and do nothing at all to help once she reads how
you feel. Your father needs a letter as well. He may not realize the destructive effect that it has on his
children.
● Lastly, have a plan in mind when all else fails that is not self-destructive. Life passes very quickly, and you will grow up and have your own life.
Above all, you need to keep yourself safe. Never doubt that it will get better. Write back and let me know how everything is going.
The Hopeless Ant wrote the letter to _______.
A. complain about the problems
B. ask for advice
C. make his father punished
D. just play a joke.
The Hopeless Ant hated his father because __________.
| A．his father always told a lie |
| B．his father wasn’t friendly to his mother |
| C．his father divorced his mother |
| D．the Hopeless Ant couldn’t stay with his parents |
.
According to the text, which of the following advice is in greatest need for the Hopeless Ant?
| A．Keep himself safe. | B．Have a talk with his parents. |
| C．Have his own family plan. | D．Write letters to families. |

Some people love eating food right after it is cooked. I prefer food just take out from the freezer. Fruit, candy, nuts, chocolate, cake with butter cream frosting(糖霜),even peas, all of them taste delicious when frozen. In fact, I often eat them that way.
I was a kid when I picked up the habit. In my family, lots of things were thrown into the freezer —finally, two freezers—to prevent them from going bad. Among them were some of the candies my sisters and I had collected on Halloween.
If we eat when they are still warm, we’ll find ourselves taking the cookies more than we should. It’s better if we can put them into the freezer and wait. That way we’ll eat less and enjoy them more because they are hard and chewing becomes a slower, more patient effort. That’s the point about frozen butter-cream frosting. Put it in your mouth at room temperature, and it’s gone very quickly. But when it’s frozen, you can enjoy the taste much longer as it melts(融化) in your mouth.
The freezer treats a lot of fruits kindly. Take frozen grapes for example, I keep a bowl of grapes in my freezer. They become a little icy, and somehow their sweetness is improved. They are perfect and healthy dessert(点心).This is the same with oranges, apples, bananas…You might think bananas would get super-hard when frozen. Wrong! They become cool, creamy and sweet. If you have wisely covered some or all of the bananas with melted chocolate before putting them into the freezer, they will have a double taste.
As long as you aren’t eating anything that truly has to be hot, go ahead and experiment. What is the passage intended to tell us ____________.
| A．Fruit should be frozen before one eats it. | B．Frozen food is better than hot food. |
| C．The author prefers frozen food. | D．Hot food is not healthy. |
The author began to enjoy frozen food when he _________.
| A．was young | B．learned cooking | C．got married | D．got a fever |
Why does the author NOT advise us to take hot cookies?
| A．Because they need more time to prepare. |
| B．Because the taste is not good when they are hot. |
| C．Because they are too delicious to avoid our overeating. |
| D．Because we may eat them quickly and enjoy them less. |
What does the underlined word “it” in the third paragraph refer to?
| A．The taste | B．Butter cream | C．The cookie | D．Frozen butter cream frosting |
Which of the following is the advice the author gives on eating fruit?
| A．Make bananas hard. | B．Keep grapes in a bowl. |
| C．Mix kinds of fruits together. | D．Add melted chocolate to bananas. |

On the day Apple debuted the often-delayed white-colored iPhone 4, the company's marke
ting department gave a nod to the product's troubled history．
"Finally．" read the big headline Thursday above a picture of the white phone on the homepage of Apple．com．
The white model was supposed to ship alongside the black one at the iPhone 4's launch（推出） last June．But design and manufacturing complications delayed the process by 10 months, catching Apple off guard, executives say．
As CNN reported last month, earlier
test models of the white iPhone 4 produced unclear photos, especially when the flash（闪光灯） was used．Its whiteness confused the proximity sensor （距离传感器） , which detects when the phone is held next to someone's head and turns off the touch screen to save battery life．
These problems weren't present in older iPhones that came in white because they didn't have flash photography; the proximity sensor was unaffected because the front side of previous models was black．
"We thought we were there a year ago, or less than that, when we launched the iPhone 4, and we weren't," Philip Schiller, Apple's chief marketing executive, said in an interview．"It's not as simple as making something white．There's a lot more that goes into both the material science of it —how it holds up over time…but also in how it all works with the sensors．"
Ticonderoga Securities analyst Brian White predicts that the white model could help drive sales of Apple's phones．He says Apple could sell 1 million to 1．5 million every three months until the next iPhone model is unveiled, which is expected to be this fall．
Forty-five people were lined up at Apple's flagship New York store Thursday morning to buy white iPhones, according to a CNN Money report．The reason why white-colored iPhone 4 was delayed by 10 months is that _______．
| A．it's always sold out due to its popularity |
| B．it met some problems concerning design and manufacture |
| C．it lacked white manufacturing materials |
| D．its proximity sensor can't save battery life |
According to the passage, which of the following statements is TRUE?
| A．There are multi-colored models of iPhone 4． |
| B．The same design problems were also found in older white iPhones． |
| C．IPhone4 will be launched this fall． |
| D．Originally designers thought they could solve the problems before iPhone 4 was launched． |
What would be the best title for this passage?
| A．Why the White iPhone 4 Took So Long |
| B．The History of iPhone 4 |
C．The Attraction of White iPhone 4 |
| D．The Design and Manufacture of iPhone 4 |
Annealing is a way of making metal softer by heating it and then letting it cool very slowly. If metal is heated and then cooled very quickly, for example by dipping (浸) it in water, it will be very hard but also very brittle (脆) —that is , it will break easily. Metal that has been annealed is soft but does not break as easily. It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly for a certain length of time. The longer the heated metal takes to cool slowly, the softer it becomes. Annealing can also be used on other materials, such as glass. Annealing can make metal
| A．hard and tough (韧). | B．hard but brittle. |
| C．soft but tough. | D．soft and brittle. |
Why do people put hot metal in water?
| A．To make it hard. | B．To make it soft. |
C．To ma ke it cool. |
D．To make it brittle. |
As suggested by the text, how ca
n glass be made less brittle?
| A．It can be heated and then cooled quickly. |
| B．It can be cooled and then heated slowly. |
| C．It can be heated and then cooled slowly. |
| D．It can be cooled and then heated quickly. |
These days no car show is complete without an electric car, and the 2011 North American International Auto Show in Detroit, US, which ran from January 10 to 23, was no exception.
Among the fully electric vehicles on display were the Ford Focus Electric and the Honda Fit EV. BMW and Volvo also had prominent displays at the show, proving that they can produce practical, yet spacious family-oriented electric cars.
Industry insiders at the show claimed that more efficient batteries, improved performance and greater consumer acceptance could make 2011 the “year of el
ectric car”.
It’s long been clear that electric cars score heavily for convenience. They are, for instance, much easier to maintain than gasoline-powered cars. When the battery runs out, you simply replace it or recharge it, just like you would for a cell phone or a laptop.
This is also a much cheaper method than filling your tank with gasoline. Better yet, electric cars don’t emit exhaust fumes. As a result, they don’t produce environmentally damaging greenhouse gases.
It appears that improved technology is making electric cars and their maintenance much more user-friendly. So, what are the obstacles which are preventing electric cars from becoming popular and fashionable?
Home charging for electric cars could be extremely convenient for users. However, it is also a potential obstacle. For a start, installing charging stations in owners’ homes will be a challenge, particularly for those who have to park several blocks away from their homes.
Also, charging the car’s battery still takes quite a long time. It may be some time yet before you can recharge an electric car in the same time as you can refill your gas tank.
Another problem is that many electric vehicles have limited ranges that may only allow for journeys of 50 miles (80 km) or less between charges. In cases where a driver wishes to charge the car primarily at home (perhaps overnight), this limits their daily driving to the range of their vehicle.
This may be one reason why hybrid cars are now becoming more popular. A hybrid car has more than one energy source, usually a traditional gasoline fuel tank and an electric battery. It’s like a more practical version of an electric car: It’s greener than a conventional vehicle, with fewer CO2 emissions, yet it also doubles as a conventional vehicle.
“I would say that hybrid is a transition to fully electronic,” Road and Track magazine editor Richard Horman told Detroit News during the show. “The trend is for lighter, smarter, more economical cars. Of course
, electronic vehicles are meant to be that way.”
This sounds promising, particularly in light of the fact that the show featured more electric cars from big manufacturers than ever before.
However, it seems that the technology associated with electric cars is not yet able to fully meet people’s expectations. Don’t expect gasoline-powered cars to disappear from roads just yet. What made electric cars more convenient?
| A．Easier maintenance. | B．High scores on the show. |
| C．Practicality and large space. | D．Much lower prices. |
Which of the following could NOT act as a potential obstacle of electric cars?
| A．It is rough work to install charging stations at home. |
| B．It is time-consuming to charge the batteries. |
| C．The ranges between charges are limited. |
| D．There’s no need to fill the tank with petrol. |
In Paragraph 10, the underlined word “hybrid” is probably closest in meaning to ________.
| A．gasoline | B．electric | C．combined | D．separated |
The writer’s purpose in writing this passage is to_________.
| A．introduce the 2011 Auto Show in US | B．get readers informed of electric cars |
| C．comment on different types of cars | D．advertise for electric cars |
Temperature is measured by means of a thermometer (温度计). One general form of thermometer depends upon the fact that most solids and liquids expand as their temperature rises. There are one or two exceptions. There is, for instance, a kind of steel called invar (from “invariable”) which does not change its dimensions as temperature changes; it is valuable for making pendulums (钟摆), since, if the length of a pendulum changes, its time of vibration changes. It is also used for making very accurate measuring scales. In both cases, then, changes of atmospheric temperature have no effect if invar is used.
Another exception is that very odd liquid, water, which has many strange properties (特性). As water gets colder it contracts (收缩), which is ordinary behavior, until it reaches the temperature of 30℃. above freezing point. After that, as it gets colder, it expands. This is fortunate---for considering the freezing of a pond. As the water on top gets colder, it shrinks; and so, volume for volume, it becomes heavier and sinks. This goes on until all the pond is at 30℃, but after that, as the water becomes colder it expands. Therefore the colder water stays on top and freezes, covering the pond with ice. If the water went on contracting down to the freezing point, the pond would become a solid block of ice in the end. This would not worry people who live in hot climates, but it would be very serious for those who live in cold climates, especially for those who want to break the ice and catch fish which live in the cold water beneath. Invar is valuable for making pendulums because _______.
| A．it can hardly change its shape or size as temperature changes. |
| B．it will change its dimensions without the change of temperature. |

Most of us long for relationships in which we are loved and accepted. Our hearts’ desire is to give and receive love in relationships that make us feel that even if others disagree with what we do or say, they still love us, accept us, and appreciate what we give to the world. While it would be wonderful to have these types of relationships with all people, we know that’s hard to do. However, we can have such relationships with some others, but only when we first have them with ourselves—and, strangely, this is often the hardest relationship of all.
Do you love yourself? You may think you do, but do you really? There’s only one way to find out— by taking a close look at what you think, say, and do. You may not like some of what you find, but if you are serious about really loving yourself, you can use this insight to do some positive inner work. Here’re three ways for gaining greater personal insight for deeper love:
Listen Closely to Your Thoughts
Your thoughts will determine your actions. One thing helping you to listen to your thoughts is keeping a journal. It is not necessary for you to write in it every day, but it helps to record various insights you gain as you go about your life. Instead of using a big notebook, you might use a small notepad that you can keep in your pocket for easy access to record your thoughts as they occur to you. Whichever method you choose, what’s most important is that you write your thoughts down. It will help you know what’s in your heart.
Be Honest with Yourself
To do this, you should pay attention to your actions. Actions speak louder than words, and they always tell the truth. If you say you love your job, but your actions say otherwise, which do you think is more reliable? On the other hand, if you say you’re not good at a certain job, but your actions say otherwise, that’s also important. What do you do with this insight? You can use it to make more positive choices in your life. By being honest with yourself, you will act according to truth instead of just what you tell yourself.
Take Quiet Time to Listen to Your Inner Voice
This is similar to the first point, but it takes a step further— beyond the natural mind to the heart that cannot be seen. You may want to use your quiet time to think deeply. However you use this time, the key is to shut out all of the noise around you by focusing deep within yourself. Breathing deeply during quiet time will also help you focus. I know it’s hard to find quiet time during a particularly busy day, but it’s so important— even if it’s just 10 minutes a day and you have to hide somewhere to get it. Quiet time can really make a difference in your life.

"Yes, but what did we use to do before there was television?" How often we hear statements like this! Television hasn't been with us all that long, but we are already beginning to forget what the world was like without it. Before we admitted the "one-eyed monster" into our homes, we never found it difficult to occupy our spare time. We used to enjoy civilised pleasures. For instance, we used to have hobbies, entertain our friends and be entertained by them, go outside for our amusements. We even used to read books and listen to music occasionally. Now all our free time is regulated by the "goggle box". We rush home for our meals to be in time for this or that programme. A sandwich and a glass of beer will do—anything, providing it doesn't interfere with the programme. The monster demands and obtains absolute silence and attention. If any member of the family dares to open his mouth during a programme, he is quickly silenced.
Whole generations are growing up addicted to the television. Food is left uneaten, homework undone and sleep is lost. The television is a universal t
hing that makes people calm. It is now standard practice for mother to keep the children quiet by putting them in the living-room and turning on the set. It doesn't matter what the children will watch—so long as they are quiet.
Television encourages passive enjoyment. We become content with second-hand experiences. It is so easy to sit in our armchairs watching others working. Little by little, television cuts us off from the real world. We get so lazy, we choose to spend a fine day in semi-darkness. Television may be a splendid medium of communication, but it prevents us from communicating with each other. We only become aware how totally irrelevant television is to real living when we spend a holiday by the sea or in the mountains. In quiet, natural surrounding, we quickly discover how little we miss the King television..
