大学英语四级单句改错例题解析（最终版）
大学英语四级单句改错例题解析（最终版）第一篇：大学英语四级单句改错例题解析（最终版）单句改错例题解析【例1】Sorry，I haven't got any small changes on me．【解析】这里的“changes”应改为“change”，因为“change”作“零钱”解时为不可数名词。
【例2】Is the education free in all the countries？【解析】这里“education”前面的“the”要去掉，因为抽象名词表示泛指意义时不用定冠词。
【例3】Peter is stronger than him．【解析】在省略句或不完整的从句中，代词的格应跟没有省略、完整时的格一致。
这一句完整的结构应该是“Peter is stronger than he is，因此不能用“him”。
【例4】The man bought 20 dozens socks．【解析】象dozen，hundred，thousand等数量词被大于1的基数词修饰时，仍用单数形式。
所以这里的“dozens”应该改为“dozen”。
【例5】M illion of years ago，there lived a lot of huge animals on the earth．【解析】“hundreds of”，“thousands of，“millions of等结构中，不可遗漏-s。
【例6】China is still a developed country．【解析】过去分词作定语表示完成或被动之意，而现在分词作定语则表示进行或主动之意。
而中国现在仍然是一个发展中国家，因此应把“developed”改为“developing”。
【例7】What a ashamed thing to do！【解析】“ashamed”是“感觉羞耻的”，通常很少用在形容词前面作定语，一般只作表语，而“shameful”是“可耻的”，通常用在形容词前面作定语。

Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs.Experts think an asteroid big enough to destroy lots of life might strike Earth once eve ry 500，000 years.Sounds pretty rare-but if one did fall，it would be the end of the world."If we don't take care of these big asteroids，they'll take care of us，"says one scientist."It's that simple."The cure，though，might be worse than the disease.Do we really want fleets of nuclear weapons sitting around on Earth?"The world has less to fear fromdoomsday(毁灭性的) rocks than from a great nuclear fleet set against them，" said a New York Times article.21. What does the passage say about asteroids and meteoroids?A) They are heavenly bodies different in composition.B) They are heavenly bodies similar in nature.C) There are more asteroids than meteoroids.D) Asteroids are more mysterious than meteoroids.22. What do scientists say about the collision of an asteroid with Earth?A) It is very unlikely but the danger exists.B) Such a collision might occur once every 25 years.C) Collisions of smaller asteroids with Earth occur more often than expected.D) It's still too early to say whether such a collision might occur……23. What do people think of the suggestion of using nuclear weapons to alter thecourse of asteroids?A) It sounds practical but it may not solve the problem.B) It may create more problems than it might solve.C) It is a waste of money because a collision of asteroids with Earth is veryunlikely.D) Further research should be done before it is proved applicable.24. We can conclude from the passage that .A) while pushing asteroids off course nuclear weapons would destroy the worldB) asteroids racing across the night sky are likely to hit Earth in the near futureC) the worry about asteroids can be left to future generations since it is unlikelyto happen in our lifetimeD) workable solutions still have to be found to prevent a collision of asteroidswith Earth.25. Which of the following best describes the author's tone in this pass age?A) Optimistic. B) Critical. C) Objective. D) Arbitrary.Questions 26 to 30 are based on the following passage:Believe it or not，optical illusion (错觉) can cut highway crashes.Japan is a case in point.It has reduced automobile crashes on some roads by nea rly 75 percent using a simple optical illusion.Bent stripes，called chevrons (人字形)painted on the roads make drivers think that they are d riving faster than they really are，and thus drivers slow down.Now the American Association Foundation for Traffic Safety in Washington D.C.is planning to rep eat Japan's success.Starting next year,the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highwaycrashes.Excessive speed plays a major role role in as much as one fifth of all fatal traffic accidents,according to the foundation .To help reduce those accidents，the foundation will conduct its tests in areas where speed - related hazards are the greatest - curves，exit slopes，traffic c ircles，and bridges.Some studies suggestthat straight，horizontal bars painted across roads can initially cut the average speed of drivers in half.However，t raffic often returns to full speed within months as drivers become used to seeing the painted bar.Chevrons，scientists say，not only give drivers the impress ion that they are driving faster than they really are but also make a lane sppea r to be narrower.The result is a longer lasting reduction in highway speed and the number of traffic accidents.26. The passage mainly discusses .A) a new way of highway speed controlB) a new pattern for painting highwaysC) a new approach to training driversD) a new type of optical illusion27. On roads painted with chevrons drivers tend to feel that.A) they should avoid speed - related hazardsB) they are driving in the wrong laneC) they should slow down their speedD) they are approaching the speed limit28. The advantage of chevrons over straight，horizontal bars is that the former .A) can keep drivers awakeB) can cut road accidents in halfC) will have a longer effect on driversD) will look more attractive29. The American Association Foundation for Traffic Safety plans to .A) try out the Japanese method in certain areasB) change the road signs across the countryC) replace straight，horizontal bars with chevronsD) repeat the Japanese road patterns30. What does the author say about straight，horizontal bars painted acr oss roads?A) They are falling out of use in the United States.B) They tend to be ignored by drivers in a short period of time.C) They are applicable only on broad roads.D) They cannot be applied successfully to traffic circles……Questions 31 to 35 are based on the following passage:Amtrak(美国铁路客运公司)was experiencing a downswing in riders hip (客运量)along the lines comprising its rail system.Of major concern t o Amtrak and its advertising agency DDB Needham，were the long - distance wester n routes where ridership had been declining significantly.At one time，trains w ere the only practical way to cross the vast areas of the west.Trains were fast，ver，'luxurious，and quite convenient compared to other forms of transportation existing at the time.However，times change and the automolile became America's standard of convenience.Also，air travel had easily established itself as the fastest method of traveling great distances .Therefore，the task for DDB Needham was to encourage consumers to consider other aspects of train travel in order t o change their attitudes and increase the likelihood that trains would be consid ered for travel in the west.Two portions of the total market were targeted: 1) anxious fliers - those concermed with safety，relaxation，and cleanliness and 2) travel - lovers - those viewing themselves as relaxed，casual，and interested in the travel ecperience as part of their vacation.The agency then developed a campaign that focused on travel experiences such as freedom，escape，relaxation，and enjoyment of the great western outdoors.It stressed experiences gained by u sing the trains and portrayed western train trips as wonderful adventures.Adver tisements showed pictures of the beautiful scenery that could be enjoyed along s ome of the more famous western routes and emphasized the romantic names of some of these trains(Empire Builder，etc.).These ads were strategically placed among family - oriented TV shows and programs involving nature and America in order t o most effectively reach target audiences.Resultswere impressive.The Empire Bu ilder.Which was focused on in one ad.enjoyed a 15 percent increase in profits on its Chicago to Seattle route.31. What's the author's purpose in writing this passage?A) To show the inability of trains to compete with planes with respect to speedand convenience.B) To stress the influence of the automobile on America's standard of convenience.C) To emphasize the function of travel agencies in market promotion.D) To illustrate the important role of persuasive communiation in changing consum-er attitudes.32. It can be inferred from the passage that the drop in Amtrak ridership was due tothe fact that ______ .A) trains were not suitable for short distance passenger transportationB) trains were not the fastest and most convenient form of transportationC) trains were not as fast and convenient as they used to beD) trains could not compete with planes in terms of luxury and convenience33. To encourage consumers to travel by train，DDB Needham emphasized ______ .A) the freedom and convenience provided on trainsB) the practical aspests of travelC) the adventurous aspects of train tripsD) the safety and cleanliness of train trips34. The train ads were placed among family - oriented TV programs involv ing natureand America because ______ .A) they could focus on meaningful travel experiencesB) they could increase the effectiveness of the TV programsC) their profits could be increased by some 15 percentD) most travel - lovers and nervous fliers were believed to be among the audiences35. According to the passage，the Empire Builder enjoyed an increase in ridership andprofits because ______ .A) the attractiveness of its name and route was effectively advertisedB) it provided an exciting travel experienceC) its passengers could enjoy the great western outdoorsD) it was widely advertised in newspapers and magazines in Chicago and SeattleQuestions 36 to 40 are based on the following passage:Why does cream go bad faster than butter? Some researchers think they the answer，and it comes down to the structure of the food，not its chemical composition - a finding that could help rid some processed foods of chemical preservatives.C ream and butter contain pretty much the same substances，so why cream should sou r muchfaster has been a mystery.Both are emulsions - tiny globules(小球)of one liquid evenly distributed throughout another.The difference lies in what's in the globules and what's in the surrounding liquid，says Brocklehurst，who led the investigation.In cream，fatty globules and what's in the surround ing liquid，says Brocklehurst，who led the investigation.In cream，fatty globul es drift about in a sea of water.In butter，globules of a watery solution are l ocked away in a sea of fat.The bacteria which make the food go bad prefer to li ve in the watery regions of the mixture."This means that in cream，the bacteria are free to grow throughout the mixture，"he says.When the situation is revers ed，the bacteria are locked away in compartments (密封仓) buried dee p in the sea of fat.Trapped in this way，individual colonies cannot spread and rapidly run out of nutrients.They also slowly poison themselves with their wast e products."In butter，you get a self - limiting system which stops the bacteri a growing，"says Brocklehurst.The researchers are already working with food com panies keen to see if their products can be made resistant to bacterial attack t hrough alterations to the food's structure.Brocklehurst believes it will be pos sible to make the emulsions used in salad cream，for instance，more like that in butter.The key will be to do this while keeping the salad cream liquid and not turning it into a solid lump.36. The significance of Brocklehurst's research is that ______ .A) it suggested a way to keep some foods fresh without preservativesB) it discovered tiny globules in both cream and butterC) it revealed the secret of how bacteria multiply in cream and butterD) it found that cream and butter share the same chemical composition37. According to the researchers.cream sours faster than butter because bacteria_____ .A) are more evenly distributed in creamB) multiply more easily in cream than is butterC) live on less fat in cream than in butterD) produce less waste in cream t han in butter38. According to Brocklehurst，we can keep cream fresh by ______ .A) removing its fat B) killing the bacteriaC) reducing its water content D) altering its structure39.

大学英语四级改革适用(作文)模拟试卷3(题后含答案及解析)
大学英语四级改革适用（作文）模拟试卷3(题后含答案及解析) 题型有：1. WritingPart I Writing1．Write a composition entitled What do Students Need English For? You should write at least 120 words according to the outline given below in Chinese: 下图是对不同专业学生学习英语的不同目的所做的调查结果，请描述并分析此图。
正确答案：What do Students Need English For? Today, it seems that nearly everyone is studying English, especially students. But what do they study English for? A survey made by a teacher at a university gives us some hints. The results of the survey suggest that students need English for different purposes. Most students learn English because they need to read English textbooks or journals or attend English lectures, while only a few students use it to talk to English-speaking visitors, attend seminars, and write letters, etc. There are also some differences between economics students and engineering students. Compared with engineering students, economics students need to read English business textbooks and write reports in English. Therefore, from the results of the survey, we can see that the purposes students learn English for vary with the academic field students study in. Whatever the purposes are, one thing is certain: Students need English, and English teaching should be strengthened in universities. 涉及知识点：作文2．Write a composition entitled Generation Gap. You should write at least 120 words according to the outline given below in Chinese:1. 现代生活越来越好，但老年人和年青人之间的代沟却依然不可逾越；2. 产生代沟的原因；3. 解决的办法。
英语四级题型(改错与对话和选词填空)解题方法与技巧实例探讨
1. 基本情况在四级新题型考试中，改错题是作为完形填空题的置换题出现的，在实考试卷中只能是二者取其一。
所以它在考试中所占分值比例与完形填空一样，也是 10％。
改错题通常选用一篇 200 词左右的短文，其中有 10 个语法结构和用词方面的错误，分布在除首句外的 10行中。
这些错误可能是因为用错了一个词或词形变化造成的，也可能是因为多用一个词或少用一个词造成的。
用错的词可能是意义或形式容易混淆的词，可能是意义相反的词，也可能是造成语法错误或搭配错误的词；词形变化错误可能是词性、时态、语态、性、数、格等语法方面的错误。
有的错误在同一短语或句子中一眼就能辨别，有的错误则必须在充分理解上下文的基础上才能识别。
考试在答题前一定要认真阅读并理解全文，答题时要参阅和琢磨上下文。
2. 题型分析改错也是一项综合测试题型。
虽然形式不同，但其测试重点与完形填空所覆盖的测试内容大致相同。
在解答四级改错题时，应主要从以下几个方面进行观察和判断：固定搭配―考查动词词组、介词词组、形容词词组、动宾词组等固定搭配的用法；语法句法―考查单复数、虚拟语态、从句等语法现象；语义逻辑―考查上下文的语义关系，常利用反义词来混淆视听；关系连词――考查句子内部或句群之间的逻辑关系，例如因果关系、转折关系、递进或并列关系、总分关系等；指代关系――考查人称代词、物主代词、反身代词与被指代的名词的对应关系；词汇用法――与完形填空相比较而言，改错部分考查的对象除名词、动词、形容词和副词等实义词的用法外，也经常考查一些功能词的用法，如介词、连词等。

大学英语四级考试改错题型透析以及应试技巧
英语四级考试：改错题型透析以及应试技巧一、常考典型错误1、一致性方面的错误1）主谓一致主谓不一致错误是CET－6综合改错题内容之一，主要表现为主语名词与谓语动词间隔较长，首尾不能相接，造成视觉上的混淆。
例：The president of the company，together with the workers，are planning a conference for the purpose of solving financial problems．句中主语的主词为单数名词“president”，介词短语“together with the workers”与主语无关，是插入成分，故谓语动词应用单数is。
2）名词单复数有时名词可以不用复数，但是在特定的句子中由于前面有明确的量词修饰，如many，several， a number of， a variety of等等，就要变成复数形式。
例：Computer，as we all know，has many possible use in different fields．句中名词use前的修饰语many是用来修饰复数名词的，所以use应改为uses。
3）代词与先行词一致代词的主要功能是指代已出现的名词、词组或一个意群，因此代词的出现必须有所指，而且形、数等必须与前面所代的部份相符。
这是代词改错的核心。
例：A knowledge of several languages is essential to other majors' study because without them one can read books only in translation．本句中without them指的是没有几门语言的知识。
them错指a knowledge of several languages，因为其中knowledge是中心词，所以要把them改为it。

【答案及解析】
1.【答案】culture改为cultures
【解析】本题考查词汇及语法。
“文化”这一词很容易被当作抽象名词，从而使考生觉得应该把“are”改为“is”。
其实本句中“culture”为可数名词，指的是不同国家的文化，这一点从首行“multicultural”也可推断出来。
故本题需要改正的不是动词而应把“culture”变为复数形式。
2.【答案】or改为and
【解析】本句考查语义逻辑。
连词的前后部分并非二选一的关系，故不能用“or”而应使用表示并列及顺承的“and”。
此外，“most likely”也可作为得出答案的提示。
3.【答案】the other改为another
【解析】本题考查词汇用法及固定搭配。
容易误用的词或词组是常考的考点，如“another”, “the other”, “others”。
如果提到两方，应使用“one…the other…”来表示“一个……另一个……”,而本句并没有出现把文化分为两类的意思，因此不可使用“the other”,应选择不特指的“another”。
4.【答案】with改为in
【解析】本题考查介词的使用。
用某种语言表达应使用介词“in”而非“with”,但由于“with”也有“用”的意思，此类情况下容易混淆。
可回忆一个简单的句
子，如“How do you say this in English?”然后类推出答案。
5.【答案】critic改为critical
【解析】本题考查词汇用法。
修饰名词“difference”的应为形容词“critical”。
6.【答案】arrogant改为arrogantly
【解析】本题同样考查词汇用法。
须注意，“arrogant”并非在be动词之后作表语，“傲慢”之意应修饰其后的“monocultural”,故应改为副词形式“arrogantly”,用副词修饰形容词。
7.【答案】hide后加it
【解析】本句考查语法规则。
本句包含定语从句，限定主语“those”。
句意为“而那些觉察到的人也无法掩饰”。
“掩饰”的宾语为上文提到的“being arrogantly monocultural”,本句中应用“it”指代，故应在句末加上“it”。
8.【答案】culture改为cultural
【解析】本题考查词汇用法。
“文化壁垒”应为“cultural barrier”而非“culture barrier”,属形容词修饰名词。
9.【答案】block改为blocking
【解析】本题考查语法规则。
通过分析句子成分可知，“block”并非句子的谓语，因此应该使用非谓语形式。
外国人感觉到傲慢情绪并很快建立起文化壁垒，主语“foreigners”与“block”之间是主动的关系，故使用“block”的现在分词。
10.【答案】has后加been
【解析】本题考查语法规则。
本句包含定语从句，从句先行词为“requirement”,其与“neglect”之间应为被动关系，意为“这一要求被忽视”，故应根据现在完成时被动语态的要求，在“neglected”之前加“been”。
