AThe World's Largest InsectThis giant insect can be used as a toy.A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around.The child is African, and the toy is the African Goliath beetle, the largest insect in the world.The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel.African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless.1.

It covers nearly 4,000 students in senior high schools and vocational high schools in the four countries.About 78.3 percent of Chinese students said they spend more than eight hours at school and 56.7 percent said they study at least two more hours each day at home.By contrast, only 24.7 percent of their peers in the US, 20.5 percent in Japan and 15.4 percent in Korea study more than two hours after school.Around 60 percent of all students surveyed said their burden for studies was the heaviest; however, the Japanese felt their burden was the worst with respondents (应答者) reaching 79.2 percent.Among the five biggest headaches for young people in the four countries were: over－scheduling ranked first, followed by a boring leisure life, unsatisfied appearance, little time for exercise and making friends, and no spare money.“Moderate (适度的) study pressure can better drive students to develop, however, too much will squeeze (挤) their development space, and can even cause harm to their physical and psychological health,” the survey said.“Balancing their studies and all－round development is a very important task,” it said.4.

Some countries which were mainly agricultural a hundred years ago have now become industrial. New factories and towns have been built on good agricultural land. There are now fewer farms to serve a much greater population, so these farms must be more efficient in order to produce as much food as possible. There is no place in the modern agricultural world for the inefficient farmer. Unfortunately, many of the picturesque aspects of farming are disappearing in the search for efficiency. The more tractors are used, the fewer horses are needed. Everyone agrees that horses are far more pleasant to look at than tractors. But they are less efficient. Cows are usually milked by machinery nowadays, and even pigs are fed automatically. There is not much artor poetry on the modern farm, and the old traditional idea of a farm as a slow, peaceful, romantic place is totally wrong nowadays.The modern farmer has to be a mechanic, a scientist, an accountant and a gambler. The more mechanized farming becomes, the more expert the farmer has to be. He must understand what machinery is necessary for his kind of farm, and he must know how to use it efficiently. He must also understand the new technical advances in agriculture, and how to use chemical and synthetic products to improve his crops. The more workers a farmer employs, the more he must know about the problems of wages and taxes. As in any other industry，most modern farmers find it necessary to employ office staff to deal with these. But although he has more modern equipments and far more scientific aids than his grandfather had, the farmer is still dependent upon the weather. As he can never be sure what the weather will do, he must be prepared to take risks, and face the possibility of losing everything.8. The underlined word “mechanic” means __________.A. a skilled farmerB. a skilled person in using and repairingC. a workerD. a driver9. Why the idea of a farm as a slow, peaceful, romantic place is wrong nowadays?A. Because nowadays, the world gets more mechanized.B. Because cows are usually milked by machinery and pigs are fed automatically.C. The fewer horses are needed.D. No farm needs the inefficient farmer.10. How to explain “The more mechanized farming becomes，the more expert the farmer has to be”?A. With the development of agriculture, it needs farmers to become a skilled man tooperate those agricultural machines.B. With the development of agriculture, the farmer should be an accountant.C. With the development of agriculture, the farmer should be mechanized.D. With the development of agriculture, the farmer has to be a driver.11. Which of the following is NOT TRUE?A. The weather is a very important factor in agriculture.B. It’s necessary for modern farmers to have modern equipments.C. The farmers don’t have to know about their wages and taxes today.D. Nowadays, it’s necessary for farmers to use office staff.DLiving and dealing with kids can be a tough job these days, but living and dealing with parents can be even tougher.If I have learned anything in my 16 years, it is that communication is very important, both when you disagree and when you get along. With any relationship, you need to let other person know how you are feeling. If you are not able to communicate, you drift apart. When you are mad at your parents, or anyone else, not talking to them doesn’t solve anything.Communication begins with the concerns (关心) of another. It means that youcan’t just come home from school, go up to your room and ignore (不理睬) everyone. Even if you just say “Hi”, and see how their day was for five minutes, it is better than nothing.If you looked up the word “communication” in a dictionary, it would say “the exchange of ideas, the conveyance （表达）of information, correspondence （通信）, means of communication: a letter or a message”. To maintain (保持) a good relationship, you must keep communication strong. Let people know how you feel, even if it’s just by writing a note.When dealing with parents, you always have to make them feel good about how they are doing as a parent. If you are trying to make them see something as you see it, tell them that you’ll listen to what they have to say, but ask them politely to listen to you. Yelling or walking away only makes the situation worse.This is an example: one night, Sophie went to a street party with her friends. She knew she had to be home by midnight after the fireworks, but she didn’t feel she could just ask to go home. That would be rude. After all, they had been nice enough to take her along with them. Needless to say, she was late getting home. Her parents were mad at first, not when Sophie explained why she was late, they weren’t as mad and let the incident go. Communication is the key factor here. If Sophie’s parents had not been willing to listen, Sophie would have been in a lot of trouble.Communication isn’t a one-way deal: it goes both ways. Just remember: if you get into a situation like Sophie’s, telling the other person how you feel-listening is the key factor to communication.12. In the writer’s view, dealing with parents is __________ than with children.A. more difficultB. easierC. more uninterestingD. more interesting13. The main idea of the second paragraph is __________.A. the importance of friendshipB. to make your feeling known to othersC. the importance of communicationD. the disagreement between generations14. When parents and children are in communication, the key to a happy relationship is that __________.A. children should always obey their parentsB. they should be equalC. parents play the leading partD. both make the opposite know their feelings15. The example in this passage proves that ___________.A. Sophie’s parents are willing to listen to herB. Sophie is very polite to her parentsC. Sophie did well in explaining her being lateD. communication is the solution (解决办法) to misunderstanding二、阅读七选五根据短文内容，从短文后的选项中选出能填入空白的最佳选项。
