In the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer．The warning is：The sun's summertime rays(射线)are more dangerous than once thought． 　　A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone(臭氧层)in the atmosphere(大气)，which protects humans from harmful levels of ultraviolet(紫外线)radiation(放射)，will be thinner over the United States this summer．The thinner layer allows more ultraviolet rays from the sun to reach the earth．The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer(癌症)． 　　Scientists first became concerned about the ozone layer in the mid 1980s when a hole was discovered in the layer above Antarctica during the winter．The hole was caused by chemicals used in refrigerators(冰箱)and air conditioners．When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone． 　　Concern about the protective ozone layer rose more recently when data(数据) from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica．Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world．Although many countries have already begun stopping the use of ozone-destroying chemicals, the new findings are expected to advance the timetable for a total ban(禁止)of the chemicals． (1) The scientists have observed the ozone layer ________． [　　] A． since 1980 B． since last winter C． for about 20 years D． for about one year (2) The ozone layer in the atmosphere can ________． [　　] A． do a lot of good to human beings in many ways B． protect human beings from disease caused by bad weather C． do a lot of harm to human beings in the summertime D． protect human beings from harmful levels of ultraviolet radiation (3) The damage to the ozone layer was caused by ________． [　　] A． the changeable weather B． ozone destroying chemicals C． chemicals from refrigerators D． chemicals from air conditioners (4) Which of the following is NOT true? [　　] A． The use of ozone destroying chemicals has already been stoppeD． B． The ozone levels in the spring and summer over the US were low． C． More and more people have begun to protect the nature surroundings． D． Many countries have already taken measures to protect the layer．

Dog owners say dogs are smarter. However, this may not be the case. Cats tend to hide their intelligence; they don’t want praise from their owners. Cats are independent,whereas dogs are social and mostly travel in groups. Because of this, many people believe that dogs are more intelligent, but the ways of measuring the intelligence of cats and dogs are different because they are different animals. Therefore, the intelligence of cats may be underestimated. The senses of cats are more developed than those of dogs. They hear and see better than dogs.The memory of cats is a lot better than that of dogs. Cats have both longterm and short-term memory. The memory of cats is two hundred times more than that of dogs. This means that the memory of cats is even better than that of monkeys and chimpanzees. Scientific American states that cats can hold 1000 times more “data storage” than an iPad. Cats have better cognition than dogs. It is true that dogs have a better social IQ than cats, but that doesn’t mean that they are smarter than cats. Cats can solve complex problems,and can also distinguish between complex shapes. Also, the observation of cats is greater than that of any other domestic animal. If something new and different enters a house, the cat can quickly figure out what it is. This makes training a cat very easy because it is able to observe what happens very quickly, and is able to learn quicker than a dog. In conclusion, cats have the brain, but they don’t want to show it because they don’t want love; they want food and just the basic necessities in order to survive. The Huffington Post says, “ Dogs come when they’re called; cats take a message and get back to you.” This quote can show us that maybe cats are the smarter ones.1.From the first paragraph, we know cats are ______.A.socialB.independentC.stupidD.lovely2.About the memory of animals, which one of the following is true?A.Dogs>Cats>MonkeysB.Cats>Dogs>MonkeysC.Monkeys >Cats > DogsD.Cats > Monkeys > Dogs3.What makes training a cat so easy?A.That the cat doesn’t want love.B.That the cat has a better social IQ.C.That the cat has better memory than the dog.D.That the cat can observe and learn more quickly.4.How is the passage mainly developed?A.By inferring.B.y comparing.C.By listing examples.D.By giving explanations.5.What is the best title of the text?A.Dogs Have Higher Social IQs than CatsB.The Reasons Why the Cats Are IndependentC.The Intelligence of Cats Is UnderestimatedD.ogs and Cats

What will man be like in the future – in 5, 000 or even 50, 000 years from now？ We can only make a guess, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain ’s capacity. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change tool the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over very long period of time it is likely that man ’s eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life. But what about hair？ It will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald! Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own. The passage tells us about _____. A.how man’s life will be in the future B.how future man will look like C.the fact that man ’s organs will function differently in the future D.the fact that man is growing uglier as time passes There is evidence that man is changing _____.A.man has been growing taller over the past 500 years B.man has got stronger eyes than he ever had C.man’s hair is getting thinner and thinner D.man’s limbs are getting weaker because he tends to make less use of them Man’s forehead will grow larger because _____.A.he will use of only about 20% of the brain ’s capacity B.the other 80% of his brain will grow in due time C.he had rather narrow forehead a few hundred years ago D.he will have to use his brain more and more as time goes on Future man will probably ______.A.have smaller eyes B.have larger eyes C.see better D.gave to wear better glasses The reason for believing that future man will be different is that he _____.A.is always B.never stops changing C.hopes for a change D.will live a different life
