What’s the most important thing for you to have in your life? Somebody mentions hard-work, others suggest knowledge, love and luck. If you arrange（排列） the 26 English letters in order and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…26 for z, you can change an English word into a number. So hard-work becomes 8+1 +18 +4+23+15+18+11="98,meaning:98" is its mark .Knowledge :11+14 +14+23 +12+5+4+7 +5="96" ,love:12+15+22+5="54," and luck: 12+21+3+11="47," a small mark. None of these words can give one a full mark. What about money? It can’t , either. Then what else? Don’t be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude.Yes, attitude is the word. See for yourself: attitude:1+20+20+9+20+21+4+5=100，a full mark. Different attitudes lead to different courses of life. Most time people hope for a better life. It is possible that they will have a better life if they change their attitudes. When you change your manner and became friendly towards others, you’ll meet more smiling faces towards you. In the same way, if you take a positive attitude towards failure, you’ll find it’s also rewarding（有益的）though it has caused you losses（损失）.The writer thinks _________ is the most important thing in a person’s life.
| A．hard-work. | B．knowledge | C．money | D．attitude |

Play is the basic business of childhood, and in recent years research has shown the great importance of play in the development of a human being. From earliest infancy（婴儿）, every child needs opportunity and right materials for play, and the main tools of play are toys. The main function of toys is to suggest, encourage and play. To succeed in this, they must be good toys, which children will play with often, and will come back again and again. Therefore, it is important to choose suitable toys for different stages of a child’s development.
In recent years, research on baby development has shown that the standard a child is likely to reach, within the range of his inherited（遗传的）abilities, is largely determined in the first three years of his life. So a baby’s ability to benefit from the right play materials should not be underestimated. A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully.
In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toys should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability: Bricks and jigsaws（七巧板）and construction toys; painting, scribbling（涂鸦）and making things; sand and water play; toys for imaginative and pretending play—the first social games for learning to play and get on with others.
But at the third stage of play development—from five to seven or eight years old— the child is at school. But for a few more years play is still the best way of learning, at home or at school．It is easier to see which type of toys the child most enjoys.
Until the age of seven or eight, play and work mean much the same to a child．But once reading has been mastered, then books become the main source of learning. Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun. What does the writer want to tell us in the first paragraph?
Children should choose toys by themselves.
Children like playing, but they don’t need any toys.
Children should be given different toys as they grow up.
Children should be given the same toys as they grow up.
58．According to the passage, we can give the child every kind of toys ________．
| A．when he is two | B．when he is around four |
| C．when he is six | D．when he is eight |
When a child is seven years old, what is the main source of learning?
| A．Toys. | B．Books. | C．Jigsaws. | D．Paintings. |
What is the article mainly about?
| A．The importance of schooling. |
| B．The choice of toys for children. |
| C．The importance of pre-school education. |
| D．The role of play in a child’s development. |
Are you carrying too much on your back at school? You’re not alone. Back experts(专家) in the USA are worried about that young students are having back and neck problems because they are carrying too much in their backpacks .
“It hurts my back when I run,” said Ebelin Reyes, a student in Virginia. “It’s hard to get up the stairs with my backpack because it’s too heavy.” Students have to carry heavy backpacks on their backs for a whole week’s study. Ebelin is one of them. They have regular(固定的)backpacks with two straps(带子) to carry them, but a number of students with heavy loads(负担) have switched to rolling backpacks. The backpacks have wheels and can roll on the ground. Shirley Park’s backpack weighs 10 kilos, and she said, “I’ll change to a rolling backpack because I am starting to have back pain.”
How much is too much? Experts say that students should carry no more than 10% to 15% of their own body weight. A few students have had a good idea to lighten(减轻) the load: less homework.
Doctor’s suggestions:
Lighten the load. Take home only the books the students need that day.
(2) Wide straps are better. They can send out weight over your shoulders (肩)and be sure to wear backpacks with two straps.
(3) The heaviest things should be packed closest to the back.
(4) Bend(弯曲) both knees when you pick up the pack, don’t just bend over the waist(腰).The main idea of the passage is about _______.
| A．the problems made by rolling backpacks |
| B．the advantage of backpacks |
| C．the best backpacks for students |
| D．how to lighten students’ backpacks |
From what Ebelin Reyes and Shirley Park said, we know______.
| A．students like to carry heavy backpacks |
| B．students have to do a lot of homework |
| C．backpacks with wheels are bad for students |
| D．students have no time to play because of heavy backpacks |
The underlined word “switch to” means______.
| A．use for | B．turn to | C．catch up | D．begin to use |
According to the experts, it’s better for a student of 40 kilos to carry a backpack of ____ at most.
| A．10 kilos | B．8 kilos | C．6 kilos | D．7 kilos |
If students follow the doctor’s suggestions, they______.
| A．may do less homework |
| B．may feel their backpacks are lighter |
| C．can learn how to enjoy themselves |
| D．will know why to wear heavy backpacks |
Reading is a good habit, but the problem is there’s too much to read these days and too little time to read every word of it. There are hundreds of skills to help you read more in less time. Here are two skills that I think are especially good.
Preview — if it’s long and hard. Previewing is especially useful for getting a general idea of heavy reading like long magazine articles and business reports.
Here’s how to preview.
Read the first two paragraphs and the last two paragraphs carefully.
Then read only the first sentence of the other paragraphs.
Previewing doesn’t give you all the details. It keeps you from spending time on things you don’t really want － or need － or read.
Skim － if it’s short and simple. Skimming is a good way to get a general idea of light reading like popular magazines or the sports and entertainment of your daily paper.
Here’s how to skim.
Get your eyes to move fast. Sweep them across each line.
Pick up only a few key words in each line.
Everybody skims differently. You and I may not pick up the same words when we skim the same piece, but we’ll get a similar idea of what it’s all about. How many skills does the writer introduce to help us in reading?
| A．One. | B．Two. | C．Three. | D．Four. |
What should you do if you read a long article according to the writer?
| A．Read every word of it. | B．Read all the details. |
| C．Pick up a few key words in each line. | |
| D．Read the first and the last two paragraphs carefully. |
If you read a simple article, which reading skill is better to get the general idea?
| A．Previewing. | B．Skimming. | C．Reading. | D．Sweeping. |
Water is the most common substance(物质) found on the earth, but less than 1% of the earth’s water is suitable for drinking. More than 1,000,000,000 people around the world survive on just over 1 galon of water a day. Probebly more than 3,000,000,000 people may suffer from not having enough water by the year 2025. You are considered lucky if you live in a country where you can drink water out of your kitchen tap or bathroom tap. People in some countries have to pay for drinking water at home. So clean water is one of our most valuabe natural resources(资源).
In fact, peole waste(浪费) so much clean water today. In factories lots of water is wasted. At home many people are not taking showers but still baths, and many are brushing their teeth with the tap turned on. Children are no longer taught how to save water….
You can save clean water in many ways. For example, if you keep gold fish, the tank water excellent for graden plants. And when you wash a milk bottle, pour the water on your house plants. Putting a brick or a water into your toilet tank many help use less water, saving many gallons over a long time.
Using rainwater is another simple way to save clean water. You can use rainwater to wash your hands after gardening, flush the toilet, and wash your car, your pet, your driveway when they are dirty.
For the same reason, people in Malaysia are encourageed to use rainwater. If one has a house with a small garden, he would buy a huge plastic tank to keep rainwater for their daily life. We can learn from the passage ______.
| A．when man can’t live without water |
| B．where there is no water resource |

Because earthquakes happen without warning, it’s important to take steps now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water.
A person needs at least 1/2 gallon of water daily just for drinking. Store at least1 gallon of water per person per day and be prepared for a 72-hour period. It’s suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.
2. Food.
It’s always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, dried milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Flashlights and spare batteries.
Keep a flashlight beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks.
Prepare a battery –powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.
4. Clothes.
If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies. You should prepare all of the following except _______________.
| A．canned juices | B．dried fruits | C．fresh vegetables | D．dried milk |

| D．we need to prepare some supplies only at home |
Good morning, boys and girl. Today I’ll talk about going online.
We know that there are too many net bars around us. The Internet can make our lives interesting and enjoyable（令人愉快的）. Many of us like going online very much because we can learn how to use the computer. We can learn English and read some newspapers and magazines to know more around us. It can make us clever in playing computer games. Also when we can send e-mails to our friends， they can get them at once. It can help us contact（交流） people from all over the world.
But some students spend too much time playing computer games and some stay in the net bars all day and all night. Some girls even get to have boyfriends or some boys get to have girlfriends online. They write too many letters to each other. It takes them too much time to chat online so they do worse in their lessons and they don’t study well any more. I think we mustn’t get online when it is time for us to study. We can do it in summer or winter holidays. I think we should get online with our teachers or parents.
At the same time, if we have lots of free time, we can do some activities after school. We usually have activities from 4：50 to 5：50 in the afternoon . You can play basket ball or football. We also have some interest groups in school, such as drawing, singing and dancing. We can go to the English corner on Monday afternoon. We hope we can spend more time on our subjects or on such activities that we can learn a lot from and less time on the Internet.

My name is James.
In my family there’s my mother—Anna, and my father—John, and my brother—Jeff. Jeff is the joker(滑稽的人) in the family, and we like him.
My mom’s parents will visit us this Sunday. They’re very cool. Tony, that’s my grandfather, He likes music very much, and Grace, my grandmother, can dance (跳舞).
Look at the photo. These are my mom’s brother and his wife, Uncle Peter and Aunt Emma, and their son, Bill. Bill likes to play computer games, and we have a good day this Sunday.
LONDON—Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is to send a few comets (彗星) in the direction of Earth, and its orbit (轨道)will be changed. Our world will then be sent moving into a safer older part of the solar system.
This idea for improving our climate comes from a group of US NASA (美国航空航天局) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—hopefully doubling its working life.
The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid (小行星) so that it passes close by our planet and sends some of its gravitational energy (重力势能) to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter(木星) or Saturn (土星). The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to worldwide warming, although the team was actually worried about a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere (生物圈)—by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying sides, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation (误算)in orbit could fire it straight at Earth—with deadly results.
There is also the question of the moon. As the present issue of Scientific American magazine points out, if Earth was pushed out of its present location, it is “most likely the moon would be stripped (剥离)away from Earth,” it states. This would greatly change our planet’s climate.
| A．A few comets are moving to the direction of Earth. |
| B．Earth’s working life is coming to an end soon. |
| C．Earth will become too hot for mankind to keep alive. |
| D．The moon is moving farther and farther away from Earth. |
| A．12 billion | B．6 billion |
| C．18 billion | D．24 billion |
| A．The comet might hit Earth and man might lose the moon. |
| B．Earth might be moved too far away and man might die because of the coldness. |
| C．The comet might hit Jupiter or Saturn and never return to Earth. |
| D．Earth’s working life might be greatly shortened. |
| A．provide | B．benefit (收益) |
| C．share | D．Endanger |
Our factories and homes burn coal and oil. Every year we have forest fires somewhere. Many scientists believe that the climate is changing.
The earth will perhaps be warmer by about 7 degrees centigrade. At the South Pole and the North Pole, the ice will melt (融化). The sea level (海平面) will rise by about 7meters. As a result, water will cover cities like London, Tokyo and New York. Some ports and towns along the coasts will disappear under water.
Some other scientists think that the dust, smoke and pollution from coal, wood and oil fires will block out the sunrays(紫外线). Then the earth will become colder and great sheets of ice will cover Europe and North America.
When chemicals in the air mix with rain, we have acid (酸) rain. Acid rain can bring us great harm. It destroys forests and kills life in lakes and rivers.
People are beginning to see how serious the problem is. They find it important to work with nature instead of against it. They are trying to save the earth in many different ways. But one of the most important things to do is to make people understand that saving the earth is saving ourselves. Some scientists believe that .
A. the earth is growing warmer
B. we can find oil in our forests
C. we have to burn down the forests every yearIce at the poles will if the earth gets warmer.
A. cover cities like London and Tokyo
B. raise the sea level by 7 degrees
C. become water and make the sea level rise Acid rain .
A. brings great changes in our climate
B. kills pests in lakes and forests
C. kills the fish in rivers and lakes What can we learn from the third paragraph?
A. The dust together with pollution from coal, wood and oil fires will bring us more heat from the sun.
B. The sunrays will come more because of the dust and pollution from fires.
C. As a result of the dust and pollution from coal, wood and oil fires, the earth will become colder. Which statement is TRUE?
A. People have come to know the importance of working with nature.
B. All the scientists agree that our earth is sure to become warmer and warmer.
C. The sea level will rise if the earth gets colder.
Space travel is nothing new. The first spacecraft with a human was sent up into space in 1961. Since then, people have not only traveled to space, but also many of them have lived there in space stations for some time.
The Soviet Union(前苏联) sent the first space station into space in 1971. This space station was called Salyut 1. Salyut 1 was designed as a place where people could live while they observed space and did experiments. The first group of astronauts lived there for 23 days. The Soviet Union went on to make seven more Salyut space stations. At about the same time, the United States built its own space station, called Skylab.
Astronauts visited and often lived in these space stations for a short time. However, it wasn’t until the late 1980s when The Soviet Union sent the Mir space station that people began to live in space for a longer time. Mir stayed in space from 1989 until 2001, when it was decided that the space station was too old and no longer safe to live in.
Living in space stations seems to be fun, but astronauts face many problems. One of them is food. All the meals on space station are put together on Earth and sent there by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be stored in cans. The space station does not have a fridge, but it has a cool room to keep fruit and vegetables fresh. Astronauts also eat many other foods such as dried meat that do not need special care.
Without the help of gravity, sitting down to eat can be tough. Astronauts sometimes have to fix themselves to the wall while eating. They also have to be very careful to that food does not float away.Which of the following has the closest meaning to the underlined word “observed” in Paragraph 2?
| A．Discovered | B．Checked | C．Watched | D．Fixed |
What can we infer(推断)from the passage?
| A．Astronauts can never have a chance to eat fresh food when they live in space station. |
| B．The Soviet Union sent a total of 9 space stations into space in the 1970s and 1980s. |
| C．Astronauts could live in the Mir space station for no more than three weeks. |
| D．Space travel has quite a long history of more than 60 years. |
What is the best title of this passage?
| A．Exploring Space | B．Space Travel | C．Living in Space | D．Space Stations |
