‎2019届高考英语一轮复习自选训练 阅读理解33‎ Warm water freezes more quickly than cold water. 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.

Johnson nodded his smooth, dark head. That was something he knew very well. “I’ve never seen anything like it,” the manager admitted. Johnson nodded again. “No?” he said politely. Then he added, “But I think you will, sir. A very great deal of it.” He appeared to think for a moment. “I think you will find it will be on sale seven, perhaps, eight years from now.” He smiled. ‎ The manager thought that was uncertain. He said, “It is better than our fish oils. I admit that.” ‎ ‎“So I am told, sir,” agreed Johnson. ‎ ‎“Have you any plans to produce it yourself, Mr Johnson?” ‎ ‎“Would I be showing it to you if I had?” Johnson smiled again.‎ ‎“We might add some chemicals to one of our own fish oils,” said the manager. “It would be expensive to do that, even if you could,” Johnson said gently. “Besides,” he added, “I am told that this oil will be much cheaper than your best fish oils. Cheaper than any vegetable oil, in fact.” ‎ ‎“Perhaps,” said the manage. “Well, I suppose you want to make an arrangement, Mr Johnson. Shall we discuss it?” ‎ ‎“Of course,” said Johnson. “There are two ways of dealing with a situation of this sort. The usual one is to prevent it altogether or at least to delay it as long as possible. That is, of course, the best way.” The manager nodded. He knew plenty about all that. ‎ ‎“But I am so sorry for you, because, you see, that is not possible this time.” The manager had his doubts, but all he said was an inquiring(asking), “Oh?” ‎ ‎“The other way,” continued Johnson, “is to produce yourself before the trouble starts.”‎ ‎1.

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.

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。‎ ‎*********************************************************结束
