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。
【例8】We object to organize such an activity．
【解析】某些带有“to”的动词词组里的“to”是介词，而不是不定式符号，因此后面应跟名词、名词词组，如果后面是动词，就应把该动词变成动名词或与它相应的名词，这类词组有be used to，oppose ／object to，be accustomed to，relate to，look forward to，等。
【例9】Of all the sports，I like swimming mostly．
【解析】对，一般说来，实意动词都是由副词来修饰的，但有时也要看修饰动词的副词与它修饰的动词是否合意，如这句话里的mostly就与swim不合意了，因为mostly是“主要地”，“大部分地”，所以应该改为most（“最”）才合整句之意：在所有运动中，我最喜欢游泳。
【例10】No matter who comes to work in our company is welcome．
【解析】“no matter who”只能引导让步状语从句，不能引导名词性从句。因此，此句应改为whoever（＝anyone who．．．）。
【例11】The jury found the defendant guiltily．
【解析】这里的“有罪”是修饰宾语“the defendant”，而并非谓语“found”，因此要用“有罪”的形容词形式“guilty”，而不是副词形式“guiltily”。
【例12】Everybody should be given the chance to reach their goals ／aims．
【解析】要表达“达到目标”应该用动词achieve，而不是reach。
【例13】He has so many skills，which surprise me so much．
【解析】这里引导定语从句的which前有一个逗号，表示这是一个非限制性定语从句。从这句话看，这里的which 指前面整个句子，而不只是修饰它前面的skills，所以它后面的动词surprise要加－s。
【例14】The accident resulted from three deaths．
【解析】“result from”意为“是……的结果，由……而产生”，而“result in”意为“导致……结果，结果造成”，而这句话的意思明显是“这一场事故造成三人死亡”，因此应把“result from”改为“result in”。
【例15】The United Nations are a world organization for peace．
【解析】“The United Nations”（联合国）和“the United States”（美国）等虽然形式上是复数，但它们是表示单个机构或国家，因此，如果是现在时，它们后面的动词要用第三人称单数形式。
【例16】More than one person have applied for the job．
【解析】主语由more than one．．．或many a构成，谓语要用单数形式。所以这里的have应改为has。
【例17】Anyone to Greece will see many sites about which they have read．
【解析】Anyone是单数的指称，而they是复数的指称，前后不一致，因此应把they必为he ／she，或者把anyone 改为travelers或people。
【例18】Such mistakes can avoid if you are careful．
【解析】当谓语主语是谓语动词动作的承受者时，谓语动词必须用被动语态。所以这里的avoid应改为be avoided。【例19】If they were careless，they would have lost the good chance．
【解析】在非真实条件句中，表示与过去事实相反，if从句的谓语动词必须用过去完成时形式had done。
【例20】He insisted that we discussed the matter at the meeting．
【解析】在suggest，order，demand，propose，request，insist，ad- vise，require等动词后的宾语从句，谓语动词用虚拟语气“（should）＋原形动词”。
【例21】Frightened by the huge explosion outside his window，his head dived under the covers．
【解析】该句中的分词短语Frightened by the huge explosion outside his window的逻辑主语不是the boy's head，而是the boy，因此应把his head改为the boy。
【例22】People of many difference nationalities together on the same block．
【解析】“together”并非动词，不能作谓语，因此根据句子的意思，必须加上谓语live。
【例23】Having not got his letter for a long time，I didn't know what had happened to him．
【解析】分词的否定结构为not ＋分词，所以这里的having not应该改为not having。
【例24】Only then I knew I was wrong．
【解析】在以only，often，many a time，never，seldom，等为首的句型中，要形成部分倒装。所以该句应该改为Only then did I know I was wrong。
【例25】Are you going aboard next year？
【解析】“aboard”意为“上船（车、飞机）”，而“abroad”则为“出国，到另一个国家”，该句的意思明显应为“你明年出国吗？”，所以应把aboard改为abroad。
大学英语四级改革适用(段落翻译)模拟试卷46(题后含答案及解析)
大学英语四级改革适用（段落翻译）模拟试卷46(题后含答案及解析) 题型有： 5. Translation Part ⅣTranslation 1．大熊猫被称为“中国国宝(China’s national treasure)”，是中国特有的动物。大熊猫外表黑白相间，体型肥胖，是一种温顺可爱的动物。它们主要生活在中国西南地区，80％以上分布于四川境内。它们习惯居住在温暖潮湿的环境中，喜欢吃竹类。由于生育率低，对生活环境的要求又相当高，它们的数量越来越少。中国政府早已意识到这一问题的严重性，所以做出了很多努力来保护这一濒危物种。 正确答案：Referred to as “China’s national treasure”, panda is an animal unique to China. With a black and white coat as well as a fat body, it is a gentle and lovely animal. Pandas live mainly in the southwest part of China, over 80% of them living in Sichuan Province. They are accustomed to living in warm and wet environment. Bamboo is their favorite food. Because of low birth rate and high requirement for living environment, the number of pandas is declining. Having realized the seriousness of the problem, Chinese government has made a lot of efforts to protect the endangered species. 解析：l．第1句的前半句可使用过去分词短语Referred to as作状语，置于句首；“中国特有的”可译为unique to China。2．在翻译第2句时，可把大熊猫的外貌特征“外表黑白相间，体型肥胖”用介词短语Witha…coat as well as．．．body 来表达：“大熊猫是温顺可爱的动物”则视为主句，从而避免出现三个孤立的并列英语短句。3．在第3句中，“80％以上分布于四川境内”可译为独立主格结构over 80％of themliving in Sichuan Province．对该句的前半句进行补充说明。4．“(它们)喜欢吃竹类”可考虑译成一个独立的句子，理解为“它们最喜欢的食物是竹类”，用bamboo作主语可起到强调作用。5．“由于生育率低，……要求又相当高”可考虑把原因译为两个并列的名词性短语lowbirth rate和high requirement，用Because of引出这两个名词性短语。6．最后一句是个因果关系句，可考虑把前半句的“因”译为现在分词短语，置于句首，在句中充当状语；而把后半句的“果”译作主句。“来保护这一濒危物种”可译为动词不定式短语，作定语修饰“努力(efforts)”。知识模块：段落翻译 2．低碳经济(low—carbon economy)是在保护环境的基础上实现可持续发展(sustainable development)的经济模式。目前，越来越多国家正向低碳经济转型。中国也不例外。中国过去的发展模式是由高能耗、低成本制造业拉动经济增长。近年来，在经济增长的同时也破坏了环境。为了实现可持续性发展，政府已承诺将采取切实行动，发展低碳经济，保护自然环境。 正确答案：Low-carbon economy is a kind of economic mode of realizing sustainable development on the basis of environmental protection. At present, an

A) would be leaving B) am leaving C) have already left D) shall have left D)。【译文】当你到达纽约时，我已经离开纽约，前往伦敦了。 【解析】动词时态题。一般来说，状语从句用一般现在时，主句要用将来的某种时态。而时间状语by the time决定了主句要用将来完成时。本句没有与事实相反的假设，因此不用虚拟式，故排除A)；选项B）的形式能够表示将来的动作，但不是将来完成时；C）只要一般现在完成时，不是将来完成时。 42.

用的是should + 动词原形的形式，而空格处需要填入的是when引导的时间状语从句中的动词，因此不必用虚拟语气。而且从句说的是一般规律性事情，用动词的一般现在时就能够了。 43. The lawyer advised him to drop the ____ since he stands little chance to win. A) event B) incident C) case D) affair C)。【译文】律师劝她放弃这个案子、因为她几乎没有胜诉的可能。【解析】单词辨析题。Case可指“案子，案件“，根据句中出现的“律师”一词和整个句子的意思，能够选择case。其它三个选项都能够指“事件”；event指重要的事件；incident能够指普通的小事，也能够指政治事件、事变；affair指事情，复数形式指事物。 44.

With the present rate of urban growth(3. 8% in the Third World) , the majority of the population of the world will be living in cities by the year 2000. This will transform the rural-urban equation which has marked the history of mankind up to now and will call for new example and a great deal of innovation to face this phenomenon. This being so, one must accept the fact that for some years to come, no policy will be capable of stopping or reversing the present migratory trend from the rural areas to the cities in the Third World. In Africa, the urban population will reach 330 million people by the end of the century as against 150 million in 1995. The number of people living in shanty-towns (贫富窟) will inevitably increase in spite of the efforts to improve housing conditions.
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。 【例8】We object to organize such an activity． 【解析】某些带有“to”的动词词组里的“to”是介词，而不是不定式符号，因此后面应跟名词、名词词组，如果后面是动词，就应把该动词变成动名词或与它相应的名词，这类词组有be used to，oppose ／object to，be accustomed to，relate to，look forward to，等。 【例9】Of all the sports，I like swimming mostly． 【解析】对，一般说来，实意动词都是由副词来修饰的，但有时也要看修饰动词的副词与它修饰的动词是否合意，如这句话里的mostly就与swim不合意了，因为mostly是“主要地”，“大部分地”，所以应该改为most（“最”）才合整句之意：在所有运动中，我最喜欢游泳。 【例10】No matter who comes to work in our company is welcome． 【解析】“no matter who”只能引导让步状语从句，不能引导名词性从句。因此，此句应改为whoever（＝anyone who．．．）。 【例11】The jury found the defendant guiltily． 【解析】这里的“有罪”是修饰宾语“the defendant”，而并非谓语“found”，因此要用“有罪”的形容词形式“guilty”，而不是副词形式“guiltily”。 【例12】Everybody should be given the chance to reach their goals ／aims． 【解析】要表达“达到目标”应该用动词achieve，而不是reach。 【例13】He has so many skills，which surprise me so much． 【解析】这里引导定语从句的which前有一个逗号，表示这是一个非限制性定语从句。从这句话看，这里的which 指前面整个句子，而不只是修饰它前面的skills，所以它后面的动词surprise要加－s。 【例14】The accident resulted from three deaths． 【解析】“result from”意为“是……的结果，由……而产生”，而“result in”意为“导致……结果，结果造成”，而这句话的意思明显是“这一场事故造成三人死亡”，因此应把“result from”改为“result in”。 【例15】The United Nations are a world organization for peace． 【解析】“The United Nations”（联合国）和“the United States”（美国）等虽然形式上是复数，但它们是表示单个机构或国家，因此，如果是现在时，它们后面的动词要用第三人称单数形式。 【例16】More than one person have applied for the job． 【解析】主语由more than one．．．或many a构成，谓语要用单数形式。所以这里的have应改为has。 【例17】Anyone to Greece will see many sites about which they have read．

专四改错题格式
专四改错题格式 完型填空 完型填空是大学英语四级考试的一个组成部分。“完型填空部分 的目的是测试学生综合运用语言的能力”，也即理解篇章和使用词汇和语法的能力。大学英语四级考试采用的完型填空题是:“在一篇题 材熟悉、难度适中的短文(约200-250词)内留有20个空白，每个空 白为一题，每题有四个选择项，要求考生在全面理解内容的基础上选择一个最佳答案，使短文的意识和结构恢复完整"，要求考生在15分钟内填完这20个空。四级考试中的完形填空不仅测试应试者在词汇 和句子水平上运用语言的能力，还测试应试者在语篇上综合运用语言结构的能力。完形填空中所填的词是与文章的上下文紧密联系的。因此，要做好完形填空，必须要在通读全文、把握结构与大意的前提下，根据所提供的选项及句子的结构、语法、语篇等信息，通过逻辑推理、对比等手段最后确定答案.根据如上特点，结合样题来说明- -下解答完型填空的步骤与技巧。 1、通读原文，了解大意 这项考试首先是测试考生对篇章的理解能力。虽然所给出的文章被抽去了20个词，但是整篇文章的内容仍是可以理解的。样题文章 的开头写道: Wise buying is a positive way inwhich you can make your money go further.这就是文章的主题句。它说明了本文所叙述的内容，一定是与wise buying有关的。我们在通读文章时，对于文章的第一句一定要加以注意，因为完型填空的第一句一般是不命题的，
其目的就是要我们比较容易地掌握文章的主旨。 2、细读文章、初选答案 完型填空综合了词汇、结构以及阅读理解部分的测试内容，一般包括动词、介词搭配，词汇辨析(包括形近词和意近词)、固定搭配以及语法结构等等。 (1)词汇辨析 选项与选项之间构成形近词、意近词的关系。有时出题者也借助选项，考察考生对某些单词词义的精确理解。这类题在完型填空题中居多，基本都是四大类实义词(名词、动词、形容词和副词)的辨析。例如68题save, preserve, raise以及retain的辨析，结合后面提示:我们的词“money",不难选择出正确答案save.而preserve 有保留、保存、保护的意思，raise也是及物动词，常与不及物动词rise 混淆，retain 含有词根re几tain,有保留的意思。这类题其实是老题型词汇部分的变相考察，所以考生在做复习时参考老题型的词汇部分也有很大帮助的。有些题还可以借助上下文的提示做出，例如82题，根据上文提示，不难选出正确答案appliance(家用电器)。(2)介词辨析介词的用法中多考察介词与名词、介词与形容词及及介词与动词的搭配和用法。例如样题中的69、74、 86 题，其中69是个固定搭配，add to意为“增加”。 (3)固定搭配 (4)语法结构 这里讲到的语法结构，是指主语从句，宾语从句，定语从句以及

Choose one word, phrase or statement that best completes the sentence. 1．______, he still kept on working. A．In case he was worn out B．Even if he was worn out C．Though he was worn out D．Provided he was worn out 正确答案：C 解析：连词搭配题。由still一词可以看出，前后语义存在转折关系。though 意为“虽然；尽管”，表示转折，符合句意，故C为答案。in case意为“万一；假使”，表示假设，因此排除A；even if意为“即使；虽然”，引导的从句往往表示假设，因此排除B；provided意为“假如；倘若”，表示假设，因此排除D。知识模块：语法词汇 2．The italicized part in the sentence “Many people observed the ship leaving the harbor. “ is an______. A．object complement B．adverbial C．object D．appositive 正确答案：A 解析：句子成分题。many people为主语，observed为谓语，the ship为宾语，leaving the harbor解释说明宾语the ship的状态，为宾语补足语，故A为答案。知识模块：语法词汇 3．Which of the following italicized parts is a predicative clause? A．I feel it a pity that I haven’t been to the get-together. B．It is estimated that the vase is 2,000 years old. C．It’s not known who he is. D．My hope is that he will keep it a secret for ever. 正确答案：D 解析：句子成分题。表语是回答主语“是什么”或“怎么样”的语法成分，因此D中that引导的是表语从句，故为答案。A中that引导的是宾语从句，前
