Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail(桶) with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make. 1. Hundreds of years ago, Sir Francis Bacon found _______. A. the temperature of warm water drops faster than that of cold water B. warm water is heavier than cold water C. warm water has the same temperature as cold water D. warm water is not as useful as cold water 2. What Sir Francis Bacon said was right, but people didn't believe him until _______. A. late in the 20th century B. early in the 20th century C. three years ago D. late in the 19th century 3. Leave a pail with warm water and another pail with cold water in the same low temperature, you’ll find that _______. A. cold water freezes first B. warm water turns into ice before cold water C. warm water and cold water freeze at the same time D. much of cold water is changed into air. 4. Why does warm water freeze first in the same freezing weather? A. Because some of the warm water turns to vapor, the amount(数量) becomes less than that of cold water. B. Because warm water is lighter than cold water. C. Because the temperature of warm water is lower than that of cold water. D. Because cold water freezes with more difficulty than warm water. 【答案与解析】本文介绍热水比冷水结冰快的现象。 1. A。细节题。据第1句和第2句可知答案为A。 2. A。细节题。根据 But few people believe him until 1970 可知答案为A。 3. B。细节题。根据文章第1句可得得答案为B。 4.

Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering. 1. The main reason for one is poor memory is that _______. A. his father or mother may have a poor memory B. He does not use his name or legs for some time C. his memory is not often used D. he can’t read or write 2. If you do not use your arms or legs for some time _______. A. you can’t use them any more B. they will become stronger C. they become weak and won’t become strong until you use them again. D. they will become neither stronger nor weaker 3. Which of the following is NOT true? A. Your memory works in the same way as your arms or legs. B. Your memory, like your arms or legs, becomes weak if you don’t give it enough chance for practice. C. Don’t learn how to read and write if you want to have a better memory. D. A good memory comes from more practice. 4. Some people can’t read or write, but they usually have better memories, because _______. A. they have save much trouble B. they have saved much time to remember things C. they have to use their memories all the time D. they can’t write everything in a little notebook 5. Which is the best title for this passage? A. Don’t Stop Using Your Arms Or Legs B. How To Have a Good Memory C. Strong Arms And Good Memories D. Learn From the People 【答案与解析】本文讲述有关记忆力的一些知识。 1.

Bees are special because they divide up their work. Each bee has a certain job to do. The busiest bee is the worker. Workers build the nest, called a hive. Inside the hive, workers make a honeycomb from wax(蜂蜡). They store honey there for food. Workers are always cleaning and fixing the hive. They even stand at the opening and fan their wings to cool the hive. Worker bees will attack anything—even people—to keep their hive safe. Another kind of bee is the drone(雄蜂). Drones are male bees, and their job is to fly with the queen bee and mate with her. After the queen mates, the worker bees drive the drones away. The drones then starve to death. The third kind of bee is the queen. Each hive needs only one queen, and her job is laying eggs. She can lay as many as 2, 000 eggs a day. 1. The bee’s nest is called a _______. A. drone B. honeycomb C. hive D. wax 2. Wax is used to make the _______. A. nest B. honeycomb C. fan D. hive 3. Which jobs do workers do? A. They lay 2, 000 eggs each day and build a nest. B. They mate with the queen bee and then starve. C. They clean the hive and keep it cool. D. They attack the queen bee. 4. According to the story, bees _______. A. are very dangerous insects B. will attack anything or anyone to protect the hive, if necessary C. are like any other insect that flies D. eat each other as food 5. The drone is driven away when its job is finished, because _______. A. it attacked the workers B. it is no longer needed in the hive C. the queen bee has died D. it ate the queen bee 【答案与解析】本文介绍了蜜蜂社会的分工及生活情况。 1. C。细节题。根据句子Workers build the nest, called a hive可推知此题答案为C。 2. B。细节题。根据句子Inside the hive, workers make a honeycomb from wax可推知此题答案为B。 3. C。细节题。根据第3段第3句和第4两句工蜂总是打扫蜂房，用翅膀扇凉蜂房可推知此题答案为C。 4. B。细节题。根据文章第3段最后一句：工蜂为了保护蜂房的安全会对包括人类在内的任何东西进行攻击。由此可推知此题答案为B。 5. B。推断题。根据文章第4段所说雄蜂的工作就是跟蜂后交配，任务完成后，它已无存在的必要，于是，就被工蜂赶走饿死。由此可推知此题答案为B。 B In most towns today, you can see teenagers standing over electronic machines with flashing lights, shooting at spaceships from other planets and dropping bombs on strange monsters(恶魔). The machines have names like Space Warrior, Dark Invader and so on. It used to be believed that damage was done only to those strange visitors from outer space, but now it seems that they are striking back. Many teenagers like electronic games so much that they can’t stop playing. They spend hours tightly holding the joystick controls and constantly pressing buttons marked “fire”. They develop pains on their fingers because of the constant pressure. They play and play that the pains have no chance to cure properly. The rapid wrist movement required to guide the spaceship across the screen causes another problem: The muscles of the wrist and arm become so inflamed and swollen(充血红肿) that they press against the bones. This condition is what doctors now call “Space Warrior’s Wrist”. Other strange aches and pains also are likely to affect the elbows and shoulders. Another even more alarming problem is shown by the case of a 17-year-old girl which was recently reported in the British Medical Journal. She had been playing various kinds of electronic games for more than two hours a day. Her father repaired games and machines and she could use the cassettes and systems in his workshop as often as she liked. One day, after playing a game called Dark Invader, she lost consciousness(晕倒) and fell to the floor. Doctors who examined her found she was suffering from an unusual illness caused by lights flashing at a particular frequency. 1. Electronic games are found very popular with _______. A. people living in towns B. students studying in high schools C. girls working in their father’s workshops D. young people 2. “Space Warrior’s Wrist” is caused by _______. A. constantly pressing the buttons B. rapidly moving across the screen C. tightly holding the joystick controls D. inflamed and swollen muscles of the wrist 3. The case of a 17-year-old girl given by the writer shows that the writer _______. A. supports playing electronic games B. feels very sorry for the girl C. disagreed with young people’s playing electronic games D. feels worried about young people’s poor health 4. From the passage we can conclude that playing electronic games is _______. A. enjoyable and helpful to the study B. exciting but harmful to the health and study C. interesting but harmless to the eyes D. amusing and satisfying (1—4 DACB) 【答案解析】本文介绍了电游对青少年学生的吸引及由此带来身体等方面的危害。 1. D。细节题。根据 In most towns today, you can see teenagers standing… 可知答案选 D。(注：teenagers 指十几岁的青少年) 2. A。细节题。 根据第2段 They develop pains on their fingers because of the constant pressure…This condition is what doctors now call “Space Warrior’s Wrist” 可知其根源是不停地压按钮，故选答案 A。 3. C。推断题。根据Another even more alarming problem is shown by the case of a 17-year-old girl which was recently reported in the British Medical Journal 可知作者把这个情况称为更加令人惊恐的，显示了作者不赞同青少人玩电游，故选 C。 4. B。推断题。阅读全文可知玩电游的主要是正处于长身体和学习的青少年，玩电游富于刺激，但是侵占了学习时间，还会得 “Space Warrior’s Wrist” 等病，损害了身体健康，故选答案 B。 C Perhaps you have heard a lot about the Internet, but what is it, do you know? The Internet is a network. It uses the telephone to join millions of computers together around the world. Maybe that doesn’t sound very interesting. But when you’ve joined to the Internet, there are lots and lots of things you can do. You can send E-mails to your friends, and they can get them in a few seconds. You can also do with all kinds of information on the World Wide Web (WWW). There are many different kinds of computers now. They all can be joined to the Internet. Most of them are small machines sitting on people’s desks at home, but there are still many others in schools, offices or large companies. These computers are owned by people and companies, but no one really owns the Internet itself. There are lots of places for you to go into the Internet. For example, your school may have the Internet. You can use it during lessons or free time. Libraries often have computers joined to the Internet. You are welcome to use it at only time. Thanks to the Internet, the world is becoming smaller and smaller. It is possible for you to work at home with a computer in front, getting and sending the information you need. You can buy or sell whatever you want by the Internet. But do you know 98% of the information on the Internet is in English? So what will English be like tomorrow? 1. What is the passage mainly about? A. Internet. B. Information. C. Computers. D. E-mails. 2. Which is the quickest and cheapest way to send messages to your friends? A. By post. B. By E-mail. C. By telephone. D. By satellite. 3. Which may be the most possible place for people to work in tomorrow? A. In the office. B. At school. C. At home. D. In the company. 4. Whose the owner of the Internet? A. The headmaster. B. The officer. C. The user. D. No one. 5. What does the writer try to tell us with the last two sentences? A. English is important in using the Internet. B. the Internet is more and more popular. C. Most of the information is in English. D. Every computer must have the Internet. 【答案与解析】这是一篇关于 Internet 的说明文，它介绍了什么是Internet，Internet 的用途，它的贡献等等。 1. A。主旨题。文章的每一段都谈到了 Internet，所以我们可以推断文章的主要内容是 Internet。 2. B。细节题。在第2段中谈到 You can send E-mail to your friends, and they can get them in a few seconds，相比其他选项，E-mail 当然是最快的。 3. C。细节题。最后一段的第2句讲到 It’s possible for you to work at home with a computer in front，所以明天我们极有可能 at home 工作了。 4. D。判断题。根据全文我们得知，我们可以在 school, libraries, home 等地方使用 Internet，所有的拥有者是大家，并不是某一个人或某一行业的从业者。 5. A。推断题。最后两句告诉我们：98% of the information on the Internet is in English，也就是说英语在 Internet 的应用是非常广泛，非常重要的，除 A 选项外，没有一个选项能全部概括这句话的意思。 原创精品资源学科网独家享有版权，侵权必究！2 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$ Unit 2 Life in the Future Reading 主题阅读 夯实基础 A The computer is a useful machine.
