　　英语四级考试备考提分练习题阅读理解

　　In bringing up children，every parent watches eagerly the child‘s acquisition (学会) of each new skill- the first spoken words，the first independent steps，or the beginning of reading and writing.It is often tempting to hurry the child beyond his natural learning rate，but this can set up dangerous feelings of failure and states of worry in the child might be encouraged to learn to read before he knows the meaning of the words he reads.On the other hand，though，if a child is left alone too much，or without any learning opportunities，he loses his natural enthusiasm for life and his desire to find out new things for himself.

　　Parents vary greatly in their degree of strictness towards their children.Some may be especially strict in money matters.Others are sever over times of coming home at night or punctuality for meals.In general，the controls imposed represent the needs of the parents and the values of the community as much as the child‘s own happiness.

　　As regard the development of moral standards in the growing child，consistency is very important in parental teaching.To forbid a thing one day and excuse it the next is no foundation for morality(道德)。Also，parents should realize that “ example is better than precept ”。If they are not sincere and do not practice what they preach(说教)，their children may grow confused and emotionally insecure when they grow old enough to think for themselves，and realize they have been to some extent fooled.

　　A sudden awareness of a marked difference between their parents‘ principles and their morals can be a dangerous disappointment.

　　答案及解析：

　　1.[B] 事实细节题。第1段第1句中的every parent，often等词表明这种做法在父母中是非常普遍的，显然B与之相符。A说法无原文依据，且由原文可看出题干所述现象是很难避免的;C中dangerous—词在原文中本是修饰其他情绪，故C不符;D是过多地让孩子自己一个独处的后果，不是题干所述行为的后果。

　　2.[C] 推理判断题。第1段第2句说明父母逼得太过分，应避免。最后一句则说明对小孩太放任自流同样不利。由这两点，我们可以做出如下判断：父母对孩子的“严”和“松”之间有一个恰当的“度”。C与之相符。

　　3.[C] 事实细节题。文章第2段表明：不同的家长对孩子的管制程度不同;家长对小孩的管制不仅是为了孩子个人的幸福，也反映了父母的需要以及社区的价值观，故C与原文相符。

　　4.[D] 词义理解题。由precept所在句可猜测precept应与example相对，且与下文的preach意思相近，故D正确。

　　5.[A] 推理判断题。第3段提到父母应该避免讲一套做一套，结合最后一段可得出结论：关于思想道德教育问题，父母应以身作则，带头遵循，故A正确。

　　Although many of us may feel air-conditioners bring relief from hot, humid or polluted outside air, they pose many potential health hazards. Much research has looked at how the movement of air inside a closed environment---such as an office building---can spread disease or expose people in the building to harmful chemicals.

　　One of the more widely publicized dangers is that of Legionnaire’s disease, which was first recognized inthe 1970s. This was found to have affected people in buildings with air-conditioning systems in which warmair pumped out of the system’ cooling towers was somehow sucked back into the air intake (通风口),in mostcases due to poor design. The warm air, filled with bacteria,was combined with cooled, conditioned air andwas then circulated around various parts of the building. Studies showed that even people outside such buildings were at risk if they walked past air exhaust pipes.

　　Large air-conditioning systems add water to the air they circulate by means of humidifiers (湿度调节器).Inolder systems, the water used for this process is kept in special reservoirs, the bottoms of which providebreeding grounds for bacteria which can find their way into the ventilation (通风)system. The risk to human health from this situation has been highlighted by the fact that the immune systems (免疫系统)of approximately half of workers in air-conditioned office buildings have developed the ability to fight off the organisms found at the bottom of system reservoirs. But chemicals called “biocides”are added to reservoirs to make them germ-free, and they are dangerous in their own right in sufficient quantities, as they often contain compounds strongly linked to cancers.

　　Finally, it should be pointed out that the artificial climatic environment created by air-conditioners canalso affect us. In a natural environment, whether indoor or outdoor, there are small variations in temperature and humidity. Indeed, the human body has long been accustomed to these normal changes. In an air-conditioned living or working environment, however, body temperatures remain well under37℃, our normal temperature. This leads to a weakened immune system and thus greater exposure to diseases such as colds and flu.

　　练习题：

　　Choose correct answers to the question:

　　1.What do we know about Legionnaire’s disease from the passage?

　　A.It was the most widely concerned office hazard.

　　B.It can affect people both inside and outside the building.

　　C.It happens only in air-conditioned office buildings.

　　D.It does not develop in well-designed buildings.

　　2.In the old air-conditioned systems, bacteria first develop______.

　　A.in the reservoirs

　　B. in the ventilation system

　　c. in the humidifiers

　　D. in the air intake

　　3.The fact that about half of workers developed the ability to fight off the bacteria may__.

　　A.relieve people’s worry about the danger caused by the bacteria

　　B.help people find an effective way to get rid of the bacteria

　　C.reflect the serious danger brought by the bacteria

　　D.cause serious disease such as cancers to people

　　4.The author most probably wants the readers to treat biocides with an attitude of_.

　　A.caution

　　B.trust

　　C.enthusiasm

　　D.criticism

　　5.The last paragraph implies that our immune system can be weakened when _

　　A.we live in an artificial climatic environment

　　B.there are variations in temperature and humidity

　　C.our body temperatures often remain not high enough

　　D.we are often exposed to diseases such as colds and flu

　　参考答案及解析

　　1.[B] 事实细节题。本题主要考査复合句的理解。第2段最后一句表明B是正确选项。选项A中的most和C中的only都太绝对了，文中并未对选项A和C中的相关说法加以这样的限定。选项D也太绝对了，第2段第3句只是说到“大多数情况下是因为空调设计欠佳所致”,并不是说所有设计良好的大厦就不会发生这种情况。

　　2.[A] 事实细节題。本题考查复合句的理解。只要明白第3段第2句这个非限制性定语从句中的the bottoms of which中的which是指上文的reservoirs,问题就不难解决了。

　　3.[C] 事实细节题。本题考查被动语态长句的理解。在第3段第3句中，关键词是highlight,选项C是对原句主谓部分的近义替换。选项A和B在文中皆无提及，选项D是过度使用生物杀灭剂的后果，与本题干的情况无关。

　　4.[A] 观点态度题。第3段最后两句讨论生物杀灭剂的用处，其中最后一句中的but, dangerous和cancers等词说明作者认为要慎用这种杀灭剂。作者并没对杀灭剂全盘否定，只是说过量使用会引发危险，因此选项D不对。

　　5.[C] 推理判断題。本题考查代词的理解。解题的关键在于理解最后一句中的This是指上一句所说的情况。选项A中所说的人造环境不是使免疫系统变弱的必然条件。选项B是保持免疫系统健康的条件。选项D是免疫系统变弱后的影响。

　　We can see how the product life cycle works by looking at the introduction of instant coffee. When it was introduced, most people did not like it as well as “regular” coffee, and it took several years to gain general acceptance (introduction stage). At one point, though, instant coffee grew rapidly in popularity, and many brands were introduced (stage of rapid growth). After a while, people became attached to one brand and sales leveled off (stage of maturity). Sales went into a slight decline (衰退) when freeze-dried coffees were introduced (stage of decline).

　　The importance of the product life cycle to marketers is this: Different stages in the product life cycle call for different strategies. The goal is to extend product life so that sales and profits do not decline. One strategy is called market modification. It means that marketing managers look for new users and market sections. Did you know, for example, that the backpacks that so many students carry today were originally designed for the military?

　　Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens. A marketer may re-position the product to appeal to new market sections.

　　Another product extension strategy is called product modification. It involves changing product quality, features, or style to attract new users or more usage from present users. American auto manufacturers are using quality improvement as one way to recapture world markets. Note, also, how auto manufacturers once changed styles dramatically from year to year to keep demand from falling.

　　26. According to the passage, when people grow fond of one particular brand of a product, its sales will ________.

　　A) decrease gradually

　　B) remain at the same level

　　C) become unstable

　　D) improve enormously

　　27. The first paragraph tells us that a new product is ________.

　　A) not easily accepted by the public

　　B) often inferior to old ones at first

　　C) often more expensive than old ones

　　D) usually introduced to satisfy different tastes

　　28. Marketers need to know which of the four stages a product is in so as to ________.

　　A) promote its production

　　B) work out marketing policies

　　C) speed up its life cycle

　　D) increase its popularity

　　29. The author mentions the example of “backpacks” (Line 4, Para. 2) to show the importance of ________.

　　A) pleasing the young as well as the old

　　B) increasing usage among students

　　C) exploring new market sections

　　D) serving both military and civil needs

　　30. In order to recover their share of the world market, U.S. auto makers are ________.

　　B) increasing product features

　　C) modernizing product style

　　D) re-positioning their product in the market

　　参考答案：26. D 27. D 28. A 29.B 30. A

By usingthese programs on a regular basis, students can improvetheir proficiency in alanguage while proceeding at their own pace.

　　Science students take advantage ofcomputers in many ways. Using computer graphic capabilities, forexample, botanystudents can represent and analyze different plant growth patterns. Medicalstudents can learn tointerpret computerized images of internal body structures.Physics students can complete complex calculations farmore quickly than theycould without the use of computer.

　　Similarly, business and accountingstudents find that computer spreadsheet programs are all but indispensabletomany aspects of their work, while students pursuing careers in graphic arts,marketing, and public relations find thatknowledge of computer graphic isimportant Education majors learn to develop grading systems usingcomputers,while social science students use computers for analyzing andgraphically displacing their research results.
