【篇一】2021年上半年大学英语四级阅读理解及解析

　　A remarkable variety of insects live in this planetMore species of insects exist than all other animalspecies together. Insects have survived on earth formore than 300 million years, and may possess theability to survive for millions more.

　　Insects can be found almost everywhere -- on thehighest mountains and on the bottom of rushingstreams, in the cold South Pole and in bubbling hot springs. They dig through the ground,jump and sing in the trees,and run and dance in the air. They come in many different colorsand various shapes. Insects are extremely useful to humans, pollinating (授粉)our crops aswell as flowers in meadows, forests, deserts and otherareas. But licks and some insects, such asmosquitoes and fleas, can transmit disease.

　　There are many reasons why insects are so successful at surviving. Their amazing ability toadapt permits them to live in extreme ranges of temperatures and environments. The oneplace they have not yet been found to any major extent is in the open oceans. Insects cansurvive on a wide range, of natural and artificial foods—paint, pepper, glue, books, grain,cotton，other insects, plants and animals Because they are small they can hide in tiny spaces.

　　A strong, hard but flexible shell covers their soft organs and is resistant to chemicals, waterand physical impact. Their wings give them the option of flying away from dangeroussituations or toward food or males. Also, insects have an enormous reproductive capacity: AnAfrican ant queen can lay as many as 43,000 eggs a day.

　　Another reason for their success is the strategy of protective color. An insect may be rightbefore our eyes, but nearly invisible because it is cleverly disguised like a green leaf, lump ofbrown soil, gray lichen (青苔),a seed or some other natural object Some insects use bright, boldcolors to send warning signalsthat they taste bad,sting or are poison.Others have wingpatterns that look like the eyes of a huge predator, bitter-tasting insects; hungry enemies arefooled into avoiding them.

参考答案

　　1.[D] 事实细节题。本题考查对复合句的理解。本题涉及两个段落，第2段及第3段都提及昆虫大量生长的地方，第3段第3句中的The one place指出了答案。

　　2.[B] 事实细节题。本题考查对复杂句的理解。第4段第1句指出了答案。protect…from…是对resistant to的同义替换。

　　3.[B] 推理判断题。本题考查对长句的理解。最后一段第2句中的nearly invisible表明昆虫伪装是为了不被发现，因此B为正确选项。其他选项虽然都是昆虫伪装的目的，但都与伪装成自然物体无关。

　　4.[D] 推理判断题。本题考查对含有分词结构句子的理解。根据第2段倒数第2句中的useful及分词结构pollinating可推断昆虫对植物的生长有益处。选项A、B、C中都有any,过于绝对。由第3段第2、3句可知选项A不对。文章虽在开头指出昆虫存活的年代久远，但全文未提到它是存活时间最长的生物，所以选项B错误。至于昆虫的食物，第3段倒数第2句有提及,但只是a wide range of,由此可排除选项C。

　　5.[B] 主旨大意题。本文前两段首先描述了昆虫生存了很长的时间，并能在各种地方生长，然后引出文章要讨论的重点，即昆虫为什么能成功存活。第3段第1句为本文的中心句，因此本题正确选项为B。

【篇二】2021年上半年大学英语四级阅读理解及解析

　　A new analysis of federal money that public schools receive for low-income students shows that a record number of the nation’s school districts will receive less in the coming academic year than they did for theone just ended.

　　For the 2005-2006 school year, spending under the Department of Education’s Title I program, which helps low-achieving children in high-poverty areas, is increasing by 3.2 percent, to $12.6 billion. But because of population shifts, growing numbers of poor children, newer census data and complex formulas that determine how the money is divided, more than two-thirds of the districts, or 8,843, will not receive as much financing as before.

　　The analysis, based on data from the department, was made by the Center on Education Policy, a group advocating for public schools. A similar study by the group last year showed that 55 percent of the schools would receive less money than they did in the previous year.

　　“It's an alarming number,” said Tom Fagan, a former department official who conducted the analysis. “It’s clear that the amount of overall increase is not keeping pace with the number of poor kids.”

　　Susan Aspey, a department spokeswoman, defended the spending levels for Title I，saying, “President Bush and Congress have invested record amounts of funding to help the nation’s neediest students.”

　　But Mr. Fagan said the increasing number of districts that are losing money is making it harder for the schools to meet the goals of the federal No Child Left Behind Act, the Bush administration's signature education program, which measures progress through annual tests in math, reading and science. That is giving critics of the program more grounds to accuse the administration of not sufficiently financing the program while demanding greater results.

　　Title I provides the largest component of financing for No Child Left Behind.

　　“The federal government is concentrating more money in fewer districts," said John F. Jennings, the president and chief executive of the Center on Education Policy. “It means there is lots of anger and lots of tension. They're asking us to do more and more with less and less.”

　　练习题：

　　Choose correct answers to the question:

　　1.As it is indicated in the passage, the new analysis _____.

　　A.studied the federal money spent on low-income students

　　B.aimed at promoting the establishment of more public schools

　　C.showed that about half the schools would receive less money

　　D.was conducted by the Department of Education’s Title I program

　　2.Which of the following factors does NOT lead to the result that more than two-thirds of thedistricts will get more poorly financed?

　　A.People often move from one place to another.

　　B.There are more children from poor families.

　　C.The way of distributing money has changed.

　　D.Spending under the Title I program decreased.

　　3.Susan Aspey looks at the funding by the government with _______.

　　A.criticism

　　B.consent

　　C.Indifference

　　D.expectation

　　4.According to Tom Fagan, ______.

　　A.the government has done its best to finance the poor children

　　B.the goals of No Child Left Behind Act are difficult to realize

　　C.the way of measuring progress by annual tests should be changed

　　D.the Bush government shouldn't have approved the Title I program

　　5.When the government concentrates more money in fewer districts, _____.

　　A.more poor children will get benefited

　　B.more public schools will have to be closed

　　C.it will arouse more people’s dissatisfaction

　　D.No Child Left Behind Act will be realized sooner

　　参考答案

　　1.[A] 事实细节题。本题考査对长句的理解。从第1段首句中的“…of…”这一结构可知这个分析是要研究联邦政府资金问题的。所以排除B。由第3段第1句可知这项分析是由the Center on Education Policy 进行的，因此排除选项D。根据第3段最后一句，选项C中show的行为主体应为similar study。

　　2.[D] 事实细节题。本题考查因果关系。第2段第2句指出有三个原因造成超过2/3的地区得到的资金减少，选项A、B、C是对这三个原因的近义改写，但其中选项C与原句的形式分别，容易造成误选。

　　3.[B] 观点态度题。本题考查文人物的观点。苏珊·阿斯贝的观点态度只能从第5段推断出，从这一段中的defended和record amount of funding可知她对教育部的拨款数是认同的。选项A和C都是贬义词，不可 能表达她的观点;选项D虽是褒义词,但苏珊是在陈述已发生的事实，而不是发表对教育部的期望。

　　4.[B] 推理判断题。本题考查对复合句的理解。由文中第6段第1句中的harder... to meet...可知选项B正确。选项C干扰性，要排除这个干扰，关键是要理解第6段第1句中由which引导的非限制性定语从句的作 用。这个从句是对前面“the Bush administration's signature education program”的附加事实信息，不属于汤姆·法甘的看法。

　　5.[C] 推理判断题。根据第6段第1句可知选项A和D与事实不符。最后一段倒数第2句中的anger和tension两词，可推断人们对此表示不满。

【篇三】2021年上半年大学英语四级阅读理解及解析

　　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.

　　练习题：

　　Choose correct answers to the question:

　　1.Eagerly watching the child’s acquisition of new skill ______

　　A.can be avoided

　　B.is universal among parents

　　C.sets up dangerous states of worry in the child

　　D.will make him lose interest in learning new things

　　2.In the process of children’s learning new skills parents ________

　　A. should encourage them to read before they know the meaning of the words they read

　　B. should not expect too much of them

　　C. should achieve a balance between pushing them too hard and leaving them on their own

　　D.should creative as many learning opportunities as possible

　　3.The second paragraph mainly tells us that _________

　　A. parents should be strict with their children

　　B. parental controls reflect only the needs of the parents and the values of the community.

　　C. parental restrictions vary, and are not always enforced for the benefit of the children alone.

　　D. parental vary in their strictness towards their children according to the situation.

　　4.The word “precept” (Line3, Para.3) probably means “_______”

　　A. Idea

　　B.punishment

　　C. behavior

　　D. instruction

　　5.In moral matters, parents should ________

　　A. observe the rules themselves

　　B. be aware of the marked difference between adults and children

　　C. forbid things which have no foundation in morality

　　D.consistently ensure the security of their children

　　参考答案

　　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。
