阅读理解

    Scientific experiments can sometimes go wrong and when they do, the results may range from the disastrous (灾难性的) to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.

    The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country's bees. He imported a very active type of African bee from Tanzania and mated (交配) it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, which was the scientist's name, had a total success on his hands.

    Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry. They attacked the native bees and drove them from their living places.

    But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (刺), began to attack their neighbours—cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings.

    This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them.

(1)、The results of the South American experiment         .

 

A、are not important B、are not yet certain C、have caused a serious trouble D、have proved to be wrong
(2)、The experiment mentioned in this passage was designed to         .
A、make African bees less active B、increase the number of bees in Brazil C、make Brazilian bees more easy-going D、increase the amount of honey in Brazil
(3)、Which of the following may be the cause of the new bees' attacking personalities?
A、Their bad temper. B、Their hard work. C、Their production of honey. D、Their living environment.
(4)、The last paragraph implies that         .
A、the bees prefer to live in Brazil B、the bees must be stopped from moving north C、the bees may bring about trouble in more countries D、the bees have been driven to Central and North America

    Today, a man talked very loud on his phone on a train between Malvern and Reading, making many passengers upset. I wonder how he would react if I were to read my newspaperoutloudonthetrain, Ihave never had the courage to do it, though.

    Why not give it a try? Perhaps you should take lessons on a

    musical instrument. The late musician Dennis Brian is said to have

    asked a fellow train passenger to turn off his radio. When his

    request was refused, he took out his French horn(号) and started to practice.

    I don't see how musical instruments can help improve manners in public. Don't do to others what you wouldn't like to be done to yourself. Once, a passenger next to me talked out loud on his mobile phone. I left my seat quietly, giving him some privacy to finish his conversation. He realized this and apologised to me. When his phone rang again later, he left his seat to answer it. You see, a bit of respect and cooperation can do the job better.

    I did read my newspaper out loud on a train, and it turned out well. The guy took it in good part, and we chatted happily all the way to Edinburgh.

    I have not tried reading my newspaper out loud on a train, but ,several years ago, I read some chapters from Harry Porter to my bored and noisy children. Several passengers seemed to appreciate what I did.

    One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

    Listen — Listen when they are talking. Don't say anything unless they ask you a question. Sometimes it's not necessary for you to have anything to say; they just need someone to talk to about their feelings.

    Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don't do everything they want you to do. Try to take an extra (额外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.

    Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can't stay with me at my worst, you are sure not to deserve (值得) to be with me at my best.” Always remember this! If you don't want to stay with your friends when they're in hard times, then you don't deserve to be with them when they're having a good time!

    ______ — Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you'll remember these things when you're all old!

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

    In the tenth grade,I began working for free at a vet's that was run by a friend. I wanted to get experience for what I thought would be my future job. However,on one particular Saturday morning I learnt something perhaps more important.

    The hospital was in the middle of one of the poorer sections of the city and some people could only pay for the most basic treatments. On this Saturday,a man and his young son,who was probably about 7 years old,walked in with a small cat in a cardboard box. There was something wrong with the cat's left eye. But the man could not afford to pay for the cost of the medicine. He kept quiet for a while,and then he asked where the nearest animal shelter was. Hearing this,his son cried and started to argue with him. All of a sudden,an older woman who was sitting in the waiting room stood up,walked up to the counter,and told the man that she would pay for the cost. The man thanked her and the son got to keep a healthy cat.

    I always thought it was the right thing to help out a needy person,but I only saw people do acts of kindness on TV or in movies. What the woman did made me believe that these things do happen in real life,and quite often.

Now,when I can't decide whether to help someone who is in need,I remember this woman,and then I have the courage to step up to the plate. Sometimes other people follow.

    Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元) in our brains.

    Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate it, whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions, they also tell us that there is a biological basis for the way we understand other people.

    Mirror neurons can undoubtedly be found all over our brains, but especially in the area which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to (for example: “The hand took hold of the ball”), the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).

    Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.

    Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact. Indeed, it may turn out to be the equivalent for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does-well, perhaps you'll understand why.
