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。

所以该句的ashamed应该改为shameful。

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。

3. 解题技巧1) 首先，通读全文，把握文章全貌，抓住文章主旨大意；2) 然后，根据上述 5 类改错题中常见的出题点，按图索骥，对号入座。

注意把跳过一时判断不出的题目；3) 最后，再通读一遍全文，做好扫尾工作，解决难题，复查做好的题。

4. 实战演练下面，我们以一份六级试卷中的改错题为例，说明改错题型的解题步骤与方法。

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。

Goods are eitheragricultural (like maize) or manufactured (likecars). Services are such things like education, 1.________ medicine, and commerce. These people provide 2.________ goods; some provide services. Other people provideboth goods or services. For example, in the same 3.________ garage a man may buy a car or some service whichhelps him maintain his car.The work people do is called as economic 4.________ activity.

Economists study our every daylives and the general life of our communities in orderto understand the whole economic system of which weare a part.

Theycan be helpful to the teacher, or are in need of help 1.themselves. Sometimes, I think parents are too hardto their children. I have seen many parents of this 2.kind. I often have the problem of parents coming inand telling me what they really treat their kids. They 3.tell me that they usually stand over their kinds whenthey do their homework. They check their work andmake big fuss over the grades. They criticize the kids 4.over everything having to do with school. Myresponse usually is: ”well, you know, he is really agood kid. He is fine in my class. Maybe you shouldnot be too strict with them.” 5.We want parents to realize the fact that teachersare professors at working with children. They have 6.observed many children and many parents. Becauseof this, and because of their specialized training,teachers can be realistic about children. Teachersknow whether parents want their children to do well 7.and to behave well. But teachers know less what 8.children should be able to do at different ages andstages. They don’t expect the 8-year-olds to do thework that can only be done by the 12-year-olds.Parents, in the contrary, often expect their children 9.to do what is usually beyond their age and ability.Obviously, this may make great harm to the 10.children’s development.1．are －> be2．be hard to －> be hard on3．what －> how4．make big fuss －> make a big fuss5．them －> him6．professors －> expertsprofessional7．whether －> \that8．less －> morebetter9．in the contrary －> on the contrary10．make harm to －> do harm toPassage 11Closure is the positive felling you get when youfinish a task. Lack of closure results from the 1.________ panicked feeling that you still have a million things todo. One way to obtain closure is divide a task into 2.________ manageable goals, list them, and check them offyour list as you finish them. For example, supposeyour historic teacher assigns three chapters to be 3.________ read. If your goal is to read all three chapters, youmay feel discouraged if you don’t complete thereading at one time. A more effective way tocomplete the assignment is to divide the reading intosmaller goals by thinking each chapter as a separate 4.________ goal. Thus you experience success as you complete.each chapter. While you have completed the overall 5.________ goal, you know you have progressed toward it.A second block to obtaining closure is unfinishedbusiness. You may have several tasks with the samedeadline. If changing from one task to another serves 6. ________ as a break, changing tasks too often waste time. 7. ________ Each time you switch, you lose momentum. Youmay be unable to change mental gears fast enough.You may find yourself thinking about the old projectwhen you should be concentrating in the new one. In 8. ________ addition, when you return to your first task, youhave to review where you are and what steps were 9. ________ left for you to finish.Often you solve this problem by determininghow much time you have free to work. If the timeavailable is short (i.e. ,an hour or less), you need towork on only one task. Alternate tasks when youhave more time. Completing one task or a largeportion of a task attributes to the feeling of closure. 10.______1．result from －> result in2．is divide －> is to divide3．historic teacher－> history teacher4．think each chapter －> think∧of each chapter5．have completed－> have∧not completed6．If－>Although7．waste －> wastes8．concentrate in －> concentrate on9．review where you are－>review where you were10．attributes to －> contribute toPassage 12Oral health care is, these days, a big, boom 1. business. According to Ralph Nader, American 2. spend some $5 billion on dental care each year. Yet,although the tremendous amounts of money, time 3.and energy giving over to oral health, dental 4. literature indicates that about half the population inthis country has lost all of his natural teeth by age 5.65. Nearly half of all people over age 20 wear a bridgeor denture, and more than 30 percent havecomplete upper and lower dentures. By age 50, oneout of every two persons have gum disease. 6.The dental profession blames neglectfulAmericans themselves. About half the population, itclaims, fails in visit the dentist regularly and some 30 7. million never did. Critics, on the other hand slam 8. the profession. It can be conservatively estimatedthat at least 15 percent of United States dentists are 9. incompetent, honest, or both, says a former 10. Pennsylvania Commissioner of Insurance. Some haveset the figure as high as 50 percent.1．boom －> booming2．American－>Americans3．although－>despite4．giving－>given5．his －> its6．have －> has7．fails in visit －> fails to visit8．never did－> never do9．United States－> the United States10．incompetent，honest，or both－> incompetent, dishonest, or both。
