美国航空航天局肯迪尼空间中心的发射场上，2000多吨重的“挑战者号”
昂首翘翅地威武地耸立着。今天，我们7名宇航员将在这里乘坐“挑战者号”
航天飞机凌云直上，冲破霄汉，直上九天，飞向那广袤缥缈、神秘莫测的太空！
航天飞机以每秒8千米的速度飞行。当远离地面400千米之后，地心引力
消失了。每个宇航员都感到自己的脸顿时“胀”大了，脚似乎也缩到身体里去了，我们的身体突然变得轻飘飘的，感到身轻如燕，已经可以在实验室空间飞
来飞去了，这时双脚也丧失了走路的功能，只要用手或其他部位碰一下周围的
物体，人就飞起来了。我觉得好玩，用一根指头着地，身体顿时就竖立起来，
完成一次倒（）立。这在地球上是多么难以想象！失去重（）力的人仿佛有一身绝妙的轻功：在原地旋转，一下子能转许多圈，就像一个陀螺，但将两臂伸开，转（）速立即减缓，如将两臂收拢，转速又加快了。
这种游戏多么有趣！
为了保持旺盛的精力，宇航员在太空每天都锻炼身体。但航天飞机中地方
有限，所以主要是在跑步机上跑步。跑步前，先将自己的双肩用4根弹性绳绑
在跑步机上，以免一用力就飞了。跑步机的速度可以调节。太空飞行对驾驶员
的身体素质要求较高，每天要跑半小时，科学家每天跑10分钟就够了。有一次，当“挑战者号”从西南方向飞入中国领空时，我就开始跑步，从东北方向飞出
中国领空时我停止跑步，前后只用了7分钟！看来我是赛跑冠军了。我童年时
看过武侠小说，那时候一直渴望能像侠客剑仙那样，飞檐走壁，腾云驾雾，今
天终于实现了。
一周的飞行生活很快就结束了。我们7个宇航员一起离开了航天飞机，感
到发肿的头皮开始放松了，两只脚又“长”了出来。下机后经过全面的体检，
各种指标基本正常，我身高增加了3.8厘米，体重下降( )了3.6千克。但没几天，我的身高、体重就复原了。

地球的“冰箱”
南极是世界上最寒冷的地方，堪称“世界寒极”。与南极遥对应的地球的北极，也是世界上有名的寒冷之地，但是北极的气温要比南极温和得多，这是因为北极的气温要比南极温和得多，这是因为北极的冰层下面是一片宁静的海洋，而且海拔也很低，海水对调节温度起了很大的作用。尤其是北极的夏天，气温可以升到很高，因此在北极地区短暂的夏季，可以看到数以百计的开花植物，苔藓、地衣和海藻更是生长得十分繁茂。
南极的年平均气温要比北极低20摄氏度，如北极点1月份的平均气温为零下40摄氏度，7月份的平均气温为0摄氏度，但南极点附近的平均气温为零下49摄氏度，寒季时可达零下80多摄氏度。
南极没有春夏秋冬四季之分，只有暖季和寒季之别。即使是11月到次年3月的暖季，南极内陆的月平均气温要在零下34至零下20摄氏度之间。
至于每年4月到10月的寒季，南极内陆的月平均气温一般在零下70至零下40摄氏度之间。
南极究竟冷到什么程度呢？1968年7月19日，美国科学家在南极洲东部的高原地区测到一项低温记录，为零下85.5摄氏度。但是在此之前，苏联东方站的气象学家于1960年8月24日记录了零下88.3摄氏度的地面温度。然而这还不是最低温度，1983年7月21日，东方站又记录了零下
89.6摄氏度的数据；同年7月，新西兰的万达站也记录了零下89.6摄氏度
的记录。另外，据有关资料介绍，挪威人于1967年初，在南极点记录了零
下94.5摄氏度的最低温度。如果这个数据是准确的话，那么这是迄今人类测量到的最低地面温度。
这样低的气温意味着什么呢？如果你在南极，这时候将会出现这样的奇怪现象：一块坚固无比的钢板掉在地上将会摔得粉碎；当你将一杯热水泼到空中时，落下来时就变成了冰雹。可想而知，如此寒冷的天气对人类和一切生命都是可怕的威胁。在南极，因寒冷而冻伤致残的事是经常发生的。

神秘的月球
夜幕降临，一轮明月升上夜空，清澈的月光洒满大地，让人产生无数遐想。文人墨客对月亮更是倍加青睐，唐代诗人张若虚的“江畔何人初见月，江月何年初照人”，还有宋代文学家苏轼的“明月几时有，把酒问青天”，都可称得上是脍炙人口的咏月佳句。
皓月当空，我们能够清楚地看到它上面有阴暗的部分和明亮的区域。早期的天文学家在观察月球时，以为阴暗的地区都有海水覆盖，因此把它们称为“月海”。事实上，到目前为止，人类还没有在月球上发现液态的水，我们肉眼所见的月球上的阴暗部分，实际上是月面上比较低洼的平原。由于一些历史原因，这个名不副实的名称保留到了现在。至今以确定的月海有22个，此外还有些地形被称为“类月海”。公认的22个月海绝大多数分布在月球正面。其中最大的“风暴洋”面积约5000000平方千米，差不多是9个法国的面积总和。大多数月海呈圆形或椭圆形，且四周多为一些封闭山脉，但也有一些月海是连成一片的。
月球上明亮的部分是山脉，那里层峦叠嶂，山脉纵横，到处都是星罗棋布的环形山。位于南极附近的贝利环形山非常大，直径约295千米，可以把整个海南岛装进去。最深的山是牛顿环形山，深达8788千米。除了环形山，月面上还有普通的山脉。高山和深谷叠现，别有一番风光。

大学英语四级阅读理解训练 Classified advertising is that advertising which is grouped in certain sections of the paper and is thus distinguished from display advertising. Such groupings as “Help Wanted”, “Real Estate”, “Lost and Found” are made, the rate charged being less than for display advertising. Classified advertisements are a convenience to the reader and a saving to the advertiser. The reader who is interested in a particular kind of advertisement finds all advertisements of that type grouped for him. The advertisers may, on this account, use a very small advertisement if it were placed among larger advertisements in the paper. It is evident that the reader approaches the classified advertisement in a different frame of mind from that in which he approaches the other advertisements in the paper. He turns to a page of classified advertisements to search for the particular advertisement that will meet his needs. As his attention is voluntary, the advertiser does not need to rely too much extent on display type to get the reader’s attention. Formerly all classified advertisements were of the same size and did not have display type. With the increase in the number of such advertisements, however, each advertiser within a certain group is competing with others in the same group for the reader’s attention. In many cases, the result has been an increase in the size of the space used and the addition of headlines and pictures. In that way, the classified advertisement has in reality advertisement. This is particularly true of real estate advertising? 1. All of the following facts are advantages of classified advertisement for advertisers EXCEPT that ____. A) classified advertisement charges less money B) it is easier to attract the attention of the target consumers C) it provides more information for the readers

To some extent, the factual knowledge can be learned; its interpretation comes only through experience. The most complicated problems in dealing with the cultural environment stem from the fact that one cannot learn culture—one has to live it. Two schools of thought exist in the business world on how to deal with cultural diversity. One is that business is business the world around, following the model of Pepsi and McDonalds. In some cases, globalization is a fact of life; however, cultural differences are still far from converging.

英语四级阅读题库含答案解析 1.Passage One Global warming may or may not be the great environmental crisis of the 21st century, but regardless of whether it is or isn’t –we won’t do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed. Al Gore calls global warming an “inconvenient truth,” as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and –without major technological breakthroughs—we can’t do much about it. From 2003 to 2050, the world’s population is projected to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. but that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world’s poor to their present poverty and freeze everyone else‘s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050. No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something.” Consider the Kyoto Protocol (京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn’t adopt tough enough policies to hit their 2008-2012 targets. The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking dependence on fossil fuels or dealing with it. The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless. 57. What is said about global warming in the first paragraph? A) It may not prove an environmental crisis at all. B) It is an issue requiring world wide commitments. C) Serious steps have been taken to avoid or stop it. D) Very little will be done to bring it under control. 58. According to the author’s understanding, what is Al Gore’s view on global warming? A) It is a reality both people and politicians are unaware of. B) It is a phenomenon that causes us many inconveniences. C) It is a problem that can be solved once it is recognized. D) It is an area we actually have little knowledge about. 59. Green house emissions will more than double by 2050 because of _______. A) economic growth B) the widening gap between the rich and poor C) wasteful use of energy D) the rapid advances of science and technology

2020年英语四级阅读理解练习题及解析(14) Among the more colorful characters of Leadville’s golden age were H.A.W.Tabor and his second wife, Elizabeth McCourt, better known as “Baby Doe”. Their history is fast becoming one of the legends of the Old West. Horace Austin Warner Tabor was a school teacher in Vermont. With his first wife and two children he left Vermont by covered wagon in 1855 to homestead in Kansas. Perhaps he did not find farming to his liking, or perhaps he was lured by rumors of fortunes to be made in Colorado mines. At any rate, a few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. “Great deposits of lead are sure to be found here.” he said. As it turned out, it was silver, not lead, that was to make Leadville’s fortune and wealth. Tabor knew little about mining himself, so he opened a general store, which sold everything from boots to salt, flour, and tobacco.『It was his custom to “grubstake” prospective miners, in other words, to supply them with food and supplies, or“grub”, while they looked for ore, in return for which he would get a share in the mine if one was discovered.』①He did this for a number of years, but no one that he aided ever found anything of value. Finally one day in the year 1878, so the story goes, two miners came in and asked for “grub”. Tabor had decided to quit supplying it because he had lost too much money that way. These were persistent, however, and Tabor was too busy to argue with them. “Oh help yourself. One more time won’t

大学英语四级阅读理解（1）We find that bright children are rarely held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming(把......按能力分班) pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all, it can be quite discouraging to be at the bottom of the top grade! Besides, it is rather unreal to grade people just according to their intellectual ability. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning. In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to cope with personal problems as well as learning how to think, to make decisions, to analyse and evaluate, and to communicate effectively. The pupils learn from each other as well as from the teacher. Sometimes the pupils work in pairs; sometimes they work on individual tasks and assignments, and they can do this at their own speed. They also have some formal class teaching when this is appropriate. We encourage our pupils to use the library, and we teach them the skills they need in order to do this efficiently. An advanced pupil can do advanced work: it does not matter what age the child is. We expect our pupils to do their best, not their least, and we give them every

3 大学英语四级阅读理解试题及答案（四） 十六 Trees should only be pruned when there is a good and clear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away of obergrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way. First, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air. One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease, but itis a wound that will heal. Often there is a race between the healing and the desease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hurs and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts yu make will bleed. If this does happen,it is, of course,impossible to paint them properly. 1.Pruning should be done to ______. a.make the tree grow taller

2020年英语四级阅读理解练习题及解析(8) When a consumer finds that an item she or he bought is faulty or in some other way does not live up to the manufacturer's claims, the first step is to present the warranty, or any other records which might help, at the store of purchase. In most cases, this action will produce results. However, if it does not, there are various means the consumer may use to gain satisfaction. A simple and common method used by many consumers is to complain directly to the store manager. In general, the “higher up” his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favor, assuming he or she has a just claim. Consumers should complain in person whenever possible, but if they cannot get to the place of purchase, it is acceptable to phone or write the complaint in a letter. Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the item in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, “The left speaker does not work at all and the sound coming out of the right one is unclear” is better than “This stereo does not work”. The store manager may advice the consumer to write to the manufacturer. If so, the consumer should do this, stating the complaint as politely and firmly as possible. If a polite complaint does not achieve the desired result, the consumer can go to a step further. She or he can threaten to take the

As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body. Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health. The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it. 1.People are finding less and less time for relaxing themselves because_____. a.they do not know how to enjoy themselves b.they do not believe that relaxation is important for health c.they are travelling fast all the time d.they are becoming busier with their work 2.According to the writer ,the most important character for a good manager is his ________. a.not fearing stress b.knowing the art of relaxation c.high sense of responsibility d.having control over performance 3.Which of the follwing statements is ture? a.We can find some ways to avoid stress b.Stress is always harmful to people
