24、Forty-thousand of the world s young children die every day. This is 15 million a year. Many of these deaths can be prevented. In fact, experts say, techniques now exist to save the lives of half of these children. The techniques are medically effective, simple to use and low cost. The biggest task h

25、as been to inform parents about these life-saving techniques. Diarrhea (腹泻 ) is the main cause of deaths among children in developing countries. Diarrhea results when the body tries to clear itself of harmful bacteria (细菌 ). The body does this by getting out liquids, sometimes uncontrollably. If too

26、 much water, sugar and salt are lost in this way, the body cannot work normally. The child may die. The United Nations International Children s Fund, UNICEF, introduces a technique. It uses a simple mixture of sugar and salt in water. The mixture does not stop diarrhea. But if used often as needed,

27、it keeps fluid(体液 ) levels normal until the body has fought off the harmful bacteria. In Egypt, for example, the treatment was used in a children s health care program in the province of Alexandria. It reduced by one-half the number of deaths caused by diarrhea. The technique has now been used throu

28、ghout the country. 54 According to the passage, a large number of children can be saved only when_. （ A） the life-saving ways are medically effective （ B） their parents are rich enough for the life-saving techniques （ C） the life-saving techniques are easy to use （ D） their parents learn the life-sa

When the fragments (碎片 ) landed i

31、n the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet? The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the

32、 southern part of the Earth. The news has caused panic. On 17 July, a fragment four kilometres wide enters the Earth s atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and

33、 an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia. Millions of people are already dead

34、 in the southern part of the Earth, but the north won t escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A

35、year later civilization has collapsed. No more than 10 million people have survived. Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs(恐龙 ) were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappear

36、ed. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn t survive in the cold climate that followed and they became extinct.

37、hole world becomes extremely cold. （ B） All the coastal cities in Africa are destroyed. （ C） The whole mankind becomes extinct. （ D） The visit of the comet results in wars. 58 Why does the author mention dinosaurs at the end of the passage? （ A） Because they could only live in the warm climate. （ B）

38、 Because they once dominated the Earth. （ C） Because their extinction indicates future disasters. （ D） Because dinosaurs and humans never live in the same age. 59 In writing the passage, the author intends to_. （ A） give an accurate description of the possible disaster in the future （ B） prove that

39、humans will sooner or later be destroyed （ C） tell the historical development of the Earth （ D） warn of a possible disaster in the future 60 It can be concluded that the passage is most probably part of a(n)_. （ A） horror story （ B） news report （ C） research paper （ D） article of popular science 60

40、It is often difficult for a man to be quite sure what tax he ought to pay to the government because it depends on so many different things: whether the man is married; how many children he has; whether he supports any relations; how much he earns; how much interest he receives; how much he has spent

41、 on his house during the year, and so on and so forth. All this makes it difficult to decide exactly how much the tax is. There was a certain artist who was always very careful to pay the proper amount. One year, after posting his check as usual, he began to wonder if he had paid enough, and after a

42、 lot of work, with a pencil and paper, he decided that he had not. He believed that he owed the government something. He was just writing another check to send to the tax-collector when the postman dropped a letter into the box at the front door. Opening it, the artist was surprised to find inside i

43、t a check for five pounds from the tax-collector. The official explained that too much had been paid, and that therefore the difference was now returned to the taxpayer. 61 It is mentioned in the passage that one has to pay tax according to_. （ A） how much education one has received （ B） whether one

44、 is single or married （ C） how old one s children are （ D） where one lives 62 The word “proper“ in the first line of the second paragraph means_. （ A） small （ B） big （ C） right （ D） wrong 63 After a lot of work,the artist thought that he had paid the government_. （ A） less tax than he should have （

45、B） more tax than he should have （ C） as much tax as usual （ D） just enough tax 64 Why did the tax-collector send a letter to the artist? （ A） To send him a new tax form. （ B） To return the money over-paid. （ C） To remind him of paying the tax. （ D） To explain the rules of tax-paying. 64 It is report

46、ed that over 300 million people in China are suffering from nearsightedness (近视 ). As more children have got eye trouble, their parents hope to cure the disease by medicine, equipment or by correcting the way children read and sit. But in fact the care given to one s eyes should start with the exerc

47、ise on one s feet. Three methods on how to protect eyes are as follows: Firstly, don t fasten your shoes too tightly. Try wearing loose socks or walking barefooted at home. When traveling, try wearing cloth shoes so as to make blood circulation(循环 ) easier. Secondly, walking on tiptoes will help imp

48、rove one s eyesight, and prevent nearsightedness. Figures show that few ballet (芭蕾舞 ) performers are nearsighted. Thirdly, rope skipping also does good to one s eyesight.

49、ller. Besides foot exercises, it is good to pull one s ears.
