2019屆高考英語一輪復(fù)習自選訓練 閱讀理解33Warm 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. Hundreds of years ago, Sir Francis Bacon found _.A. the temperature of warm water drops faster than that of cold waterB. warm water is heavier than cold waterC. warm water has the same temperature as cold waterD. warm water is not as useful as cold water2. What Sir Francis Bacon said was right, but people didn't believe him until _. A. late in the 20th centuryB. early in the 20th centuryC. three years agoD. late in the 19th century3. Leave a pail with warm water and another pail with cold water in the same low temperature, youll find that _. A. cold water freezes firstB. warm water turns into ice before cold waterC. warm water and cold water freeze at the same timeD. 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(數(shù)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.【答案與解析】本文介紹熱水比冷水結(jié)冰快的現(xiàn)象。1. A。細節(jié)題。據(jù)第1句和第2句可知答案為A。2. A。細節(jié)題。根據(jù) But few people believe him until 1970 可知答案為A。3.

Johnson nodded his smooth, dark head. That was something he knew very well. “Ive 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.
