大学英语四级单句改错例题解析
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。

大学英语四级考试—— 改错
四级考试“改错的目的是测试学生综合运用语言的能力”。
改错题的主要错误类型有主谓不一致、时态和语态错误、连接词误用、形容词与副词错误、反义词误用、非谓语动词错误、关系代词错误、介词错误、缺漏和赘述、句子结构等等。
考生在做改错题时，首先应通读短文，对文章有个大致的了解。
然后，仔细读出现10个错误的所在行，一般来说，每个错误基本都可以归入上述的某一个错误类型，看有没有出现语法错误和词汇错误。
如果通过细读确认没有语法错误和词汇错误，那就把细读扩大到该行上下各二、三行，有时甚至要联系该行所在的自然段，这时的重点必须转移到对文章的理解上来，从上下文的关系找出连接关系和逻辑关系的前后矛盾的错误。
最后应再通读一篇改正后的文章，看整篇文章总体上是否连贯一致。
1、反义词误用这是短文改错中出现频率较高也是比较有特色的一种错误类型，这类错误必须在透彻理解上下文语义的基础上才能发现并改正。
比较常见的错误有：a、派生反义词如00年1月的72题将directly改为indirectly。
b其他反义词如00年1月的77题将little改为much。
2、连接词误用连接词的错误虽然是属于传统的语法题范畴，但其用法主要根据上下文语义上的逻辑关系，也就是上下文的理解。
连接词有很多种，有并列连词，如and, but, or等，主从连词，如because, if, after等，以及其他连接介词和副词，如however, despite等。
曾经考查过的题目有00年6月的73题，将as改为than，这考查的是比较连词的搭配，根据上一行中之more即可确定改as为than。
3、指代错误这一般考查的是代词的指代，在文章当中如果说出现了代词，那么代词所指代的对象在前文中一定是出现过的，否则就会出现指代不清，所以出现代词时候，我们要注意它所指代的对象的单复数是否与代词一致。
如03年9月的S9题将it改为they，因为它指代的是前面的复数名词new houses。

CET4综合改错题
综合改错题是大学英语六级考试中一个重要的题型，它要求考生在15分钟内找出在一篇200—250词的短文内的10处错误（每行不超过一处错误，但不包括拼写或标点的错误），并根据上下文，在错误的地方增、删、改正、替换某一个词或词组，使短文语意连贯，结构正确。
总体而言，综合改错题的命题内容有如下三大方面：（1）词汇用法（2）篇章理解（3）语法知识。
以下摘录历年六级考试综合改错题中出现的有关词汇用法和篇章理解方面的错误进行具体地分析。
一、词汇用法错误1．固定搭配错误：主要是一些常用介词短语、动词短语、形容词短语的误用，另外，一些固定句型中词汇的搭配也容易出错。
对付此类错误的方法是大量记忆，熟悉这些固定的搭配。
例1：．．．about an American who had been invited to an Arab meal at one of the countries of the Middle East．（2000年6月第75题） at应改为in，in the country为固定介词短语搭配。
例2：．．．，but such reasons are totally dependent in the balance of risks and benefits for the patients．（1993年6月第 75题） in应改为on，dependent on为固定的形容词短语搭配。
例3：However，a second person thought that this was more a question of civilized behavior as good manners．（2000年6月第73题） as应改为than，more．．．than．．．为固定句型搭配， 2．单词的混用：这种错误是指误用了某个在形式或意义上与正确的单词相似的单词。
例1：Between sunrise and sunset，streets and highways are a constant source of voice from cars，buses and trucks．（1995年6月第 73题）原文讲述噪音污染，所以，此处的voice应改为noise。

Of course, most people hope to haveenough money to buy commodities and services whichare essential but which provide some particular personal satisfaction, such as toys for children, visits the cinema, and books.of our everyday lives. Economists study our every daylives and the general life of our communities in orderto understand the whole economic system of which weare a part. They try to describe the facts of theeconomy in which we live, and to explain how itworks. The economist methods should of course be strictly objective and scientific.1．like －> as2．these －> some3．or －> and4．as －> \ 去掉as5．Such economic system －> Such∧an economic system6．that －> which7．are essential －> are∧not essential 或者essential －> non-essential 8．visits the cinema －> visits∧to the cinema9．basic －> based10．The economist methods －> The economist’s met hodsThe economists’ methodsPassage 10Parents can be supportive of suspicions. 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 st rict 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.2．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 panicked feeling that you still have a million things todo. One way to obtain closure is divide a task into manageable goals, list them, and check them offyour list as you finish them. For example, supposeyour historic teacher assigns three chapters to beread. 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 separategoal. Thus you experience success as you complete.each chapter. While you have completed the overallgoal, 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 . ,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.1．result from －> result in2．is divide －> is to divide4．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.

Economists study our every daylives and the general life of our communities in orderto understand the whole economic system of which weare a part. They try to describe the facts of theeconomy in which we live, and to explain how itworks.

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.

They check their work and make big fuss over the grades. They criticize the kids 4. over everything having to do with school. My response 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 complete d6．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.

四级英语短文改错真题
四级英语短文改错真题Recently, I have came across an interesting article about a study which examined the impact of using smartphones on students' academic performance in class. According to the study, the findings showed that there are both positive and negative effects of using smartphones in the classroom.On one hand, smartphones can be a useful tool for learning. With access to the internet, students can easily search for information and resources related to their studies. This can enhance their understanding of the subjects and broaden their knowledge. Moreover, there are many educational apps available that can help students practice and improve their language skills, math abilities, and other academic areas.On the other hand, smartphones can also be a distraction in the classroom. Many students are tempted to use their phones for non-academic purposes during class time, such as checking social media or playing games. This can lead to a lack of focus and lower academic performance. Furthermore, the use of smartphones can create a barrier between students and teachers, as it may discourage face-to-face communication and interaction.In my opinion, it is important to find a balance when it comes to using smartphones in the classroom. Instead of completely banning their use, teachers can set clear rules and guidelines for smartphone usage. For example, they can allow students to use their phones for educational purposes only and during designated times. This way, students can still benefit from the advantages that smartphones offer, while minimizing the potential negative impact on their academic performance.In conclusion, the impact of using smartphones in the classroom is a complex issue. While they have the potential to enhance learning and provide useful resources, they can also be a distraction and hinder academic progress. It is crucial for educators to find a middle ground and establish policies that promote responsible smartphone use in order to create a conducive learning environment for all students.。

英语四级改错练习题
Some people, in all seriousness, say that humans will be living in space within the next hundred or so years. Planet Earth will be crowded, dirty and lack of resources. A sort of exodus [51] of mankind will begin.
Spaceships will be assembled so that they revolve around the earth. Some may orbit around Mars. These space stations will be serviced by space buses. We saw the first space bus launch in [52] April 1981. This was ""Columbia"", it made several [53] orbits around the earth and then returned, landing on a huge dry lake bed in California. ""Columbia"" will be used again. Previous spaceships have been abandoned, only the nose being used to bring the crews back to earth.[54] Upon established, each space station will [55] generate its own atmosphere and have its own agriculture. It will need to rotation to provide [56] an artificial gravity; people will be forced inwards [57] from the centre by centrifugal force.
The moon and Mars could become new sources of new materials. Driving through space will no [58] longer need Earth fuel - the energy would come from the sun. This energy would be converted from [59] electricity to work magnetic rockets.
That all sounds quite fantastically but, with [60] the rapid development of modern technology, who knows about what the future holds?
答案
51. and lack of... short 52. bus launch in... launched 53. it made several... which 54. the crews back... crew 55. Upon established... once 56. to rotation to... rotate 57. forced inwards... outwards 58. space will no... would 59. converted from... into 60. quite fantastically but... fantastic。
