Here is an astonishing and significant fact: Mental work alone cant make us tired. It sounds absurd. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?
Some scientists declare that most of our fatigue comes from our mental and emotional attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.What surprised the scientis

Alexis Pilkington was a popular 17-year-old and a well-liked athlete who had already won a soccer scholarship to college. But none of that stopped Alexis from becoming the target of online bullying (欺凌). Alexis began to receive hundreds of online unpleasant comments via the latest social networking site called www.formspring.com. In March 2010, Alexis committed suicide and although all agreed that the online bother was not the single factor that led to Alexis’ death, everyone did agree that it was a contributory factor.
Unfortunately, Alexis’ story is not unique. A 2010 study conducted by the Cyberbullying Research Center showed that cyberbullying victims were almost twice as likely to have attempted suicide compared to youth who had not experienced cyberbullying.
Suicide is obviously the extreme and no one can minimize the tragedy of it. However, there are other damages that occur as a result of aggressive bullying. It can damage self-esteem and lead to feelings of worthlessness, and also increase social isolation and make victims become withdrawn, depressed, anxious, and insecure. So what causes girls to be so unkind towards each other?
A term known as relational aggression may best describe the cause of girl-on-girl bullying. It starts with a clique (派系) usually led by a girl with a high level of social status and popularity. In order not to lose her position, she will control girls within the clique and take action if she feels threatened. At the leader’s directive the girls within the clique will spread rumors and lies and annoy other girls continuously. The bullying starts at school but will quickly go to cyberbullying due to anonymity (匿名). Girls will easily do so in the anonymity of the Internet. Ultimately the cause will be summarized as the insecurity and jealousy of one girl and the twisted loyalty of members within her clique. Underneath the confident exterior (外表) of a female bully lie desperate insecurities.The example of Alexis Pilkington is given to show .
| A．popular youth are not easy to become the target of bullying |
| B．cyberbullying is quite common among teenagers |

Which of the following is NOT the cause of bullying?
| A．Lack of security. |
| B．Jealousy of others. |
| C．Trying to be friendly. |
| D．The twisted loyalty of members within a clique. |

| A．has strong self-confidence | B．has strong leadership skills |
| C．is actually weak inside | D．is usually good at study |
Do you dream of owning your own house? Canadian Kyle MacDonald, a 26-year-old from Vancouver who is a resident in Montreal, has just achieved it. MacDonald, who has spent much of his time since graduating from college backpacking round Europe and Asia and whose main income appears to come from working as a pizza-delivery man, decided last year that he wanted to settle down. However, when he checked the real estate market, he quickly realized that he had no chance of raising the depositon a home of his own.
So he came up with an inventive solution. Using the power of the Internet, he decided to try to barter(易货贸易) his way to a house. His starting offer One red paper clip (回形针). Of course, he didn’t expect someone to offer him a house for the paper clip, he simply wanted to trade it for something that was more valuable. 14 trades later, he is now the owner of a house in Kipling, Saskatchewan.
His first trade took place when two women from his hometown offered him a pen in the shape of a fish. MacDonald then traded the fish-pen for a doorknob, then the doorknob for a stove. Further transactions brought him an electricity generator and a ski-bob, a small vehicle on tracks that people use to ride across snow and ice. After nine trades, he had a recording contract at a music studio in Toronto.
But Kyle pressed on, still convinced that he would eventually get a house. After trades which brought him the opportunity to spend a day with rock star Alice Cooper and to have a small part in a Hollywood movie, he struck gold.
When words of Kyle’s astonishing barter journey reached the people of Kipling, they decided to make their move. The population of the town is a little more than l,000, and falling fast.

Three Yale University professors agreed in a discussion that the automobile was what one of them called “Public Health Enemy No. 1 in this century”. Besides polluting the air and overcrowding the cities, cars are involved in more than half the disastrous accidents, and they contribute to heart disease “because we won’t walk anywhere any more,” said Richard Weeinaman, professor of medicine and public health.
Speaking of many of those man-made dangers of the automobile, Arthur W. Galson, professor of biology, said it was possible to make a kerosene-burning turbine car that would “lessensmog by a very large factor”. But he expressed doubt whether Americans were willing to give up moving about the countryside at 90 miles per hour in a large vehicle. “America seems wedded to the motor car—every family has to have at least two, and one has to be a convertible (敞篷汽车) with 300 horsepower,” professor Galson continued. “Is this the way of life that we choose because we treasure these values?”
For professor Sears, part of the blame lies with “a society that regards profit as a supreme value, under the illusion that anything that’s technically possible is, therefore, morally justified”. Professor Sears also called the country’s dependence on its modern automobiles “terrible economics” because of the large horsepower used simply “moving one individual to work”. But he admitted that Americans have painted themselves into a corner by allowing the national economy to become so dependent on the automobile industry.
“The solution,” Dr Weeinerman said, “is not finding a less dangerous fuel but a different system of inner city transportation. Because of the increasing use of cars, public transportation has been allowed to wither (衰弱) and grow worse, so that if you can’t walk to where you want to go, you have to have a car in most cities,” he declared. This, in turn, Dr Weeinerman contended, is responsible for the “arteriosclerosis (动脉硬化)” of public roads, for the pollution of the inner city and for the middle-class movement to the suburbs.The main idea of the passage is that .
| A．Americans are used to travelling by cars |
| B．American public transportation is growing worse |
| C．American car industry caused disastrous road accidents |
| D．American people’s health is threatened by automobiles |
It can be inferred from the passage that .
| A．Americans prefer cars to anything else |
| B．Americans are interested in fast automobiles |
| C．kerosene-burning engines cause more problems |
| D．kerosene-burning engines are green transportation |
In Paragraph 3, Professor Sears implies that .
| A．technology is always good for people |
| B．technology is a sword with two sides |
| C．more attention should be paid to social effects |
| D．US doesn’t care about the environment at all |
According to Dr Weeinerman, the best solution is .
| A．to look for a fuel alternative |
| B．to improve public transportation |
| C．to walk to where people want to go |
| D．to control the production of the automobile |
Listening to your favorite music can make a person feel great and can make their emotions change. The song you are listening to can affect how you feel. Different types of music may make you cry, laugh, or even feel anger. According to researches, music is a complex sound that causes a large variety of emotional responses in listeners.
The nature of emotions created by music has been a matter of much debate. Researches have shown that basic emotions, such as happiness, anger, fear, and sadness, can be recognized in and created by musical stimuli (刺激) in humans.
I know from experience that when I am in a bad mood, I’ll listen to my favorite CD. I don’t know what it is about the music but it just makes me feel better almost instantly. All of you have CDs or songs that make you feel great when you’re feeling down. Music has that power and none of us realize that until we really think about it. The physical effects that music has on us are almost the same as the emotional ones.
Music can change you in many ways, depending on the kind of music you are being exposed to. According to “Music and Emotions”, electronic music with loud sounds will physically affect you more easily than any other type of music. Certain types of music can give you courage and strengthen your willpower, while other types can make you relaxed. I can think of a good example for music bringing willpower and strength to you, when you are getting ready before a sport. The sport I play is football and I know that if I don’t listen to a certain mix of songs, my head is all over the place. If I listen to some certain songs I become very energized and feel better about things.
Music affects your emotions in many ways. It also affects your physical status. Music also is the key to your enjoying of a movie.

My mother is the only living person who has never communicated via email or text. She has never turned on a computer, registered an email account, used data storage media or searched the Internet. Since 1955, she has settled in Silicon Valley, married to an extremely technical specialist in applied physics and engineering, designing photometric systems for NASA. Only when Dad suffered from cancer could we convince her she needed a cell phone. Mom’s being separated from the information age is voluntary and deliberate.
Mom is still that farm girl, and she takes the most pride in it. She sees her neighbor and her community “real”. She shows no interest in the digital and virtual life. My mother saw Depression, World War II and the beginning of the Cold War before reaching voting age. She enjoyed country music on “The Sons of the Pioneers”, a Canadian broadcast. The battery was so precious a resource that radio was limited to the barn because Grandma thought it helped cows produce milk. In the age when Churchill moved millions for the first time with radio broadcasts, she only experienced live media monthly, if at all.
In her early twenties, Mom completed nurses’ training and worked in that field before marriage, family and church became her life’s concerns. She never really warmed up to television, though I think she appreciated a few of the series we watched, comedies like All in the Family. Computers, the Internet and mobile apps are simply not part of her experience.
Mom disagrees with the opinion that technology simplifies life. In her life, she sees online records, email and paperless systems as mysteries in which no written reference can assist her.
However, I can partly understand: I like such kind of experience and relationship one has with physical books. I am a child of television who only recently switched to online viewing. I’ve written down my awkward, love-hate relationship with my devices. Mom’s technophobia surely played a role here, but it works for her. She’s happiest as she is.The author’s mother began to use mobile phone when .

| A．Having so many close neighbors. |
| B．Experiencing too much all her life. |
| C．Living simply and in her own style. |
| D．Being involved in modern technology. |
What is the author’s attitude towards his mother’s such kind of experience?
| A．Critical. | B．Positive. |
| C．Neutral. | D．Negative. |
It is implied in the underlined sentence that .
| A．the author should make efforts to learn from his mother |
| B．the author prefers watching movies online to watching TV |
