1 Page 1 of 21 改错题常考要点一代词代词中主要讲解六个问题 ( 一 ) 掌握代词的几种格主格宾格所有格名词前面用代词来修饰, 只能用所有格 (my books) ( 二 ) 反身代词当主语和宾语表示同一事物时, 宾语使用反身代词 He killed himself. ( 他自杀了 ) He killed him. ( 他杀了他 ) 例 :Researchers at the University of olorado are investigating a series of indicators that could help themselves to predict earthquakes. 分析 : 错, 应改为 them 如果用反身代词 themselves, 指代对象是从句主语 that( 即名词 indicators), 这显然是错误的从句意来看,help 的宾语应该是主句主语 researchers, 故应用代词宾格而不是反身代词注意并没有错, 情态动词 could 比 can 语气弱, 表示较小的可能性 Indicator 为征兆, 这些征兆帮助他们来预言地震主语是征兆, 后面指研究者, 不是同一个事物 ( 三 ) 代词的单复数, 代词的性别在考试中如果代词打横线, 代词错误的概率是非常高的, 因此代词打横线, 应该先看代词有没有错例 :The continental divide refers to an imaginary line in the North merican Rockies that divides the waters flowing into the tlantic Ocean from it flowing into the Pacific. 分析 : 错, 应改为 those 指代复数名词 waters, it 是单数, 显然是错误的, 根据习惯故改为 those 注意 waters 一词并没有错, 它指江湖河海中的大片水域, 可用复数形式 Water 作为水是不可数名词,waters 表示水域, 通常使用复数形式, 作主语谓语动词用复数 Work 作为工作是不可数名词,work 作为作品, 可数不可数都可以, 例如 : Many of his works= much of his work, work 都表示作品例 :In 1920 the presidential candidate Warren Harding coined the word normalcy to express social and economic conditions they promised the nation.

2 Page 2 of 21 分析 : 错, 应改为 he 动作 promised 是由 Warren Harding 发出来的, 故用第三人称单数 he 来指代例 :Many critics believe that my Lwell' s most important work is not poetry, but his biography, John Keats, published the year of her death. 分析 : 错, 应改为 her his 指男性, 显然是错误的, 应改为 her 与后面的 her 同指 my Lowell. ( 四 ) Who 和 which 的区别 which 指代事物或者动物,who 指代人 who/whom son 往往要改为 whose son, whose 可以指代事物例 :The human body contains more than six hundred muscles who account for approximately forty percent of the body weight. 分析 : 错, 应改为 which 或 that 先行词不是指人, 而是指物, 关系代词不能用 who, 故改为 which 或 that 人体前面加定冠词 the, account for 占有多大的比例, 解释说明 ( 五 ) that 和 which 的区别介词后面使用 which, 而不用 that, in that 除外例 :When television was first introduced, the extent to that it would affect society could not have been foreseen. 分析 : 错, 应改为 which The extent to which, 介词加 which( 引导定语从句 ), 影响社会的程度没有被预见 ( 六 ) 定语从句的特殊省略 Reason 后面有定语从句, 中间往往省略 why, Time 后面有定语从句, 中间往往省略 when I do remember the time I heard the sweetest voice in the wild world. way 后面有定语从句, 中间省略了 in which 例 :Research on pain has been neglected, although the mainly reason people take medicine is to relieve pain. 分析 : 错, 应改为 main mainly 为副词, 不能个饰后面的名词, 故改为形容词 main 句子中 people take medicine 修饰 reason, 定语从句引导词被省略例 :ommercial expansion from city to suburb has

3 Page 3 of 21 affected the way people in the United States----. () living and working () they live and work () live and work () to live and to work 分析 : 选择, the way people... 影响了人们生活和工作的方式二介词介词是考试中出现的比较多的一个部分, 而其中考的最多的就是介词的固定搭配问题由于篇幅问题, 我们在这里仅仅举出几个例题, 在说明书手册中我们完整的列出了所有的介词搭配, 这些列出的搭配在以前的语法题中出现过, 只不过有的时候是正确的选项, 有的时候重复考 ( 一 ) 介词搭配例 :The teeth in the upper jaw function together those in the lower jaw to cut, tear, and grind food. 分析 : 和一起, 应该为 together with, 错例 :The llegheny Mountain range is rich of coal. 分析 : 错改为 be rich in 例 :The rotation of the Earth on its axis is responsible to the alternation of periods of light and darkness. 分析 : 错, 应改为 responsible for 形容词 responsible 后接名词作宾语时要加介词 for ( 二 ) 最重要的两个介词 1 介词 of 多余或者遗漏例 :Mosquitoes usually lay eggs, singly or in batches, on top stagnant water. 分析 : 错, 应改为 top of stagnant on top of 是因定表达法, 意为在上面例 :hristopher Plummer is a anadian actor who has starred in stage, television, and film productions on

4 Page 4 of 21 both sides the tlantic Ocean. 分析 : 错, 应改为 sides of the sides 为名词,the tlantic Ocean 也是名词, 中间明显少了一个介词 2 介词 by 一种情况表示被动,be+ 过去分词 +by 另一种表示通过的方式, by doing 例 :The ceremony of marriage in the United States can be performed from a justice of the peace. 分析 : 错, 应改为 performed by 谓语动词是被动式,performed 的动作执行者应该由介词 by 来引导例 :long the east coast,merican Indian women's councils could veto a declaration of war at refusing to supply moccasins and field rations. 分析 : 错, 应改为 by refusing 通过拒绝提供鞋子和粮食, 表示通过某种方式做某事要用介词 by, 故将 at refusing 改为 by refusing 例 :lgebra is the branch of mathematics concerned with operations on sets of numbers or other elements that are often represented at symbols. 分析 : 错, 应改为 by 动作的发出者应该用介词 by 来引导三谓语动词 ( 一 ) 谓语动词的主谓一致 1 主谓分割原则例 1:To the citizens of the United States, the bald eagle, merica's national bird, symbolize strength and freedom. 分析 : 错, 应改为 symbolizes 主语谓语用逗号分割开, 主语 the bald eagle 为单数, 谓语动词也应该用单数形式 2 与后者一致原则 not but, 强调 but 后面的名词,

5 Page 5 of 21 not only but also 3 与前者一致原则名词 +with/together with/as well as/including+ 复数名词, 谓语用 is, 中心词在前面, 谓语动词应该与前面的名词保持一致例 :The athlete, together with his coach and several relatives, are traveling to the Olympic Games. 分析 : 错, 与谓语动词与 the athlete 保持一致, 改为 is 4 就近原则 or, either or, neither nor, 单数名词 +or+ 复数名词 +are 如果把句子变为一般疑问句, 也就是把 be 动词提到前面, 那么变为 is 所以注意一点 : 如果是陈述句, 靠后面近, 用复数如果是疑问句, 靠前面近, 用单数例 :The structure or behavior of many protozoans are amazingly complex for single-celled animals. 分析 : 错, 应改为 and 从谓语动词是复数形式判断, 主语应该为复数,or 连接两个名词时动词和后面的名词保持一致,behavior 是用单数形式, 因此只有改为并列连词 and 才能使主谓在数上保持一致 5 定语从句主语就近原则 There are five apples that are red. apples 是复数, 因此从句谓语动词是复数例 : rocket burns propellant rapidly and most rockets carry a supply that last just a few seconds. 分析 : 错, 应改为 lasts 从句的逻辑主语 a supply 为单数, 其谓语动词应为单数形式 6the + 形容词主谓一致 The rich are not always happier than the poor. The rich 表示一类人, 应该用复数 7 倒装句的主谓一致改错题倒装句的主谓一致一般考两种情况 : a. there be 句型 there be+ 名词 + 名词, 那么最近的名词决定其形式 b. between/ among 放在句首 +be+ 名词, 名词其实是主语, 所以 be 和名词保持一致

6 Page 6 of 21 例 :There are no known society in which left-handed people predominate. 分析 :there be 句型由最近的名词决定其形式,society 当然用单数, 错,there are 改为 there is 例 :etween the foothills of the ndes and the Pacific Ocean are a dry coastal strip averaging about 30 miles in width. 分析 : 倒装句,are 改为 is 例 :mong the favorite attractions at the National ir and Space Museum in Washington.. are the film presented on the five-story-tall screen. 分析 : 错, 应改为 films, 主语实际上是名词, 应该与谓语动词保持一致 8 百分比结构的主谓一致 fifty percent of + 名词 one percent of + 名词谓语动词的形式和百分比多少没有关系, 主要取决于后面的名词, 比如 : one percent of my students + are fifty percent of my time is spent on working. 这里要强调两个结构 half of =fifty percent most of + 可数名词 + are most of + 不可数名词 + is 例 :Nearly half of the ancient meteor craters has been found in central and eastern anada. 分析 : 错, 应改为 have been 介词 of 的宾语为复数名词短语, 作主语的中心词 half 当然表复数, 相应的谓语动词应为复数形式例 :pproximately fifty percent of the package utilized in the United States are for foods and beverages. 分析 : 错, 应改为 packages 从谓语动词用复数形式判断出主语是复数名词注意 food 用复数表示不同种类的食品,beverage 用复数表示不同种类的饮料, 故 () () 均没有错

7 Page 7 of 21 ( 二 ) 谓语动词的时态 1 主要考察时间状语例 The metal aluminum has been first isolated early in the nineteenth century. 分析 :Metal, aluminum 同位语,in the nineteenth century 为明显表示过去时间的状语, 因此应该用过去时态, 把 has been 改为 was 2 For 和 since 的区别区别一 :For 后面使用时间段,since 后面使用时间点区别二 :Since 只能用在现在完成时态,For 最主要用在现在完成时和一般过去时 I has been a teacher for three years. I has been a teacher since I was a teacher for three years. 这种表达可以,for three years 表示一段时间,was 表示过去做了三年, 现在不是老师了例 : Since 1921 the budget of the United States became the primary responsibility of the president. 分析 : 错, 应改 In. since 一般要求主句用完成时态, 而句中谓语动词为过去式, 其时间状语应与之呼应, 故改 Since 为 In 例 :della Prentiss Hrghes served as manager of the leveland Orchestra since fifteen years. 分析 : 错, 应改为 for since 引导时间状语时, 主句谓语动词为一般完成时 ; 主句谓语动词为一般过去时要用介词 for; 而且一段时间用 for, 而不是 since 52. In general, prawns lived in shallow coastal waters or in streams. 自然现象和客观事实用一般现在时态,live ( 三 ) 谓语的语态语态主要表示是主动语态还是被动语态有四组动词是改错题中常考的 : 1 prove My advice proved to be wrong. 我的建议被证明是错的

8 Page 8 of 21 尽管是被证明, 但习惯上用主动 ; 例 : majority of the reports received from people claiming to have seen the legendary Loch Ness Monster have proven to be mistakes, misconceptions, or they were being tricked. 分析 : 错, 应改为 tricks 并列连词 or 在此连接名词, 如果把理解为并列句, 不仅时态不对, 语义也有问题, 故将整个句子改为名词 have proven to be 是正确的 2 Locate,Situate 这两个词可以用作主动, 表示把放置在地方 ; 确定的位置 ats locate obstacles. 蝙蝠确定障碍物的位置这两个词也可以用作被动 My school was located near the river. 区分 locate 的主动和被动比较难, 但是有一个技巧存在 :locate 如果用作主动, 后面必须跟宾语例 :The center of gravity of the human body ---- behind the hip joint. ()locates ()locating ()to locate ()is located 分析 : 空格处显然缺谓语动词, 故首先排除不能作谓语的和动词 locate 后面没有宾语, 所以用作被动, 表示位于, 所以为正确选项 3 表示需要概念的动词 need, want, require 等 My watch needed repairing My watch needed to be repaired. 4 表示人的情感的动词 move, annoy, surprise, please 等 He is so moving. 他令人感到感动 He is greatly moved. 他感到非常感动主动和被动技巧总结 : 如果句子中有一个过去分词 +by, 如果断定它是谓语的话, 前面必然有 be 动词例 :The Tennessee Valley uthority has chartered by the United States ongress in 1933 to construct dams, power structures, and flood-control works along

9 Page 9 of 21 the Tennessee River and its tributary streams. 分析 : 错, 应改为 has been chartered 由信号词 by 可知前面的谓语动词为被动语态形式四非谓语动词 ( 一 ) 分词现在分词和过去分词的区别 1 用于句首作状语, 现在分词表示主动, 过去分词表示被动例 :Won its war for independence in 1783, the United States then struggled to establish its own economic and financial system. 分析 : 分词作状语, 主要看是主动还是被动, 美国赢得应该是主动, 所以错, 改 won 为 winning 2 用于名词后面作后置定语, 现在分词表示主动, 过去分词表示被动例 :In the nineteenth century the Mohave Indians lived in the Northern Hemisphere grew their crops on river bottom lands. 分析 : 错, 生活在什么地方的人, 人生活是主动, 因此改为 living 一些动词后面必须用 doing 对于加 doing 的词来说, 考试中一般出现一个, 下面这些词都是要加 doing 的, 请考生牢记 mind, finish, enjoy, celebrate, advocate, suggest delay, quit forgive( 原谅 ),tolerate, avoid, escape( 逃避 ) spend+ 名词 +doing; have trouble/difficult/a problem/ +doing 例 :Long before the dawn of recorded history, humans celebrated to harvest their crops.

10 Page 10 of 21 分析 : 错, 应改为 harvesting 及物动词 celebrate 直接带名词名词短语或动名词短语作宾语, 故将 to harvest 改为 harvesting 例 :Some experts have advocated to bring that country into the talks, to revive the intermittent dialogue that began after the 1967 Middle East War. 分析 : 错,advocate 后面直接跟 doing, 改为 advocate bringing ( 二 ) 不定式. 动词不定式的省略 1 help 后面可以省略 to help to do help sb. to do 例 : good exercise program helps teach people to avoid the habits that might shorten the lives. 分析 : 错, 应改为 their. 定冠词在句中不如代词所有格明确, 如果 lives 后面有定语就可以用 the 注意 () 并没有错,help 后面可以接不带 to 的不定式 2 使役动词后面要省略 to, 这样的动词只有三个 make, let, have sb. do sth 注意 get 不是使役动词,get sb. to do sth. 例 : conductor used signals and gestures to let the musicians to know when to play various parts of a composition. 分析 :let 是使役动词, 后面不需要 to, 改为 know 3 感官动词 hear, feel, watch, see, notice, observe see sb do sth. 强调过程 see sb doing sth 正在做某事. 动词不定式的固定用法 (1) 表示第一人 the first woman to do sth.

11 Page 11 of 21 (2) 表示迫使的动词一般考三个, allow/ enable/ call, +sb. + to do 例 :esides providing clues to the nature of atoms, mineral analysis allows to speculate geologists about the ancient Earth. 分析 :allow...to do 是固定短语,allow 的宾语应在不定式之前, 即把改为 : allow geologists to speculate (3) 表示倾向的形容词 be more likely to do 更有可能作某事 be inclined to do 倾向于做某事 be lieable to do 易于的 be apt to do (4) 表示目的的名词, 一共有 7 个这样的词, 这一条也是最重要的固定的句式 : the purpose, the purpose of sth is to do sth. the objective 目标 aim goal reason 理由 function 功能 intension 意图例 :The function of Louis Sullivan's architecture was providing large uninterrupted floor areas and to allow ample light into the interior. 分析 :the function to provide, 错例 :The chief goal of biochemistry is for understanding the structure and behavior of the carbon-containing compounds that make up various components of a living cell. 分析 :the chief goal is to understand, 错 (5) 其他同根名词 ability to do 受到 be able to 的影响 attempt to do 企图 decision to do 决定, 受 decide 的影响 ambition,

12 Page 12 of 21 be ambitious to do effort 例 :For ancient people, myths were often attempts explanation catastrophic events such as volcanic eruptions. 分析 : 错, 应改为 to explain attempts 后应跟动词不定式短语表目的, 故将名词 explanation 改为 to explain 例 :In the early 1960's the ivil Rights movement made great efforts for registering members of minorities to vote. 分析 :efforts to register, 错. 动词不定式的其他用法 (1) be to do 表示已安排好或者注定要发生的动作, 属于将来时态的范畴 She and nne are to meet at two o'clock. (2) 不定式的完成式为 to have done, 表示不定式的动作在谓语动作之前发生, 这个完成式通常表示一般过去时 I am glad to see you. I am glad to have seen your mother yesterday. yesterday 是一般过去时, 修饰 have seen. (3) 形容词后面使用动词不定式, 主动表示被动 It is difficult to decide. 五句子的结构句子的结构主要考查四个出题方向 ( 一 ) 主语的重复名词 + 代词 + 谓语, 这个代词永远是重复的主语, 永远是错的例 :Woodrow Wilson he was an idealist who refused to make any compromises concerning the establishment of the League of Nations.

13 Page 13 of 21 分析 : 代词 he 不是同位语, 主语重复 ; 如果是下面这样的主语, 那么便是主语同位语 prolific writer, Woodrow Wilson 例 :Two unique features of the rctic they are lack of precipitation and permanently frozen ground. 分析 : 选项中的 they 和前面的主语 two unique features 重复 ( 二 ) 谓语的重复完整的句子后面又多了一个谓语, 往往改为定语从句例 : paragraph is a portion of a text consists of one or more sentences related to the same idea. 分析 : 错, 应改为 consisting of 或 which consists of 句中有两个无法连接的谓语动词, 而且前一个谓语动词下面没有划线, 故改 consists 为非谓语动词形式或在它前面加 which 使之成为从句谓语动词 ( 三 ) 谓语的缺少例 :Most mammals to maintain a relatively constant body temperature, regardless of what the air temperature might be. 分析 : 错, 应改为 maintain 句中缺谓语动词, 故去掉不定式符号 to 使 maintain 变成谓语动词 ( 四 ) 主句的重复主句的重复总是考 even, instead, during, despite 等引导的句子, 但是实际上它们无法把两个句子连接起来, 因为它们都是副词或者介词, 连接两个句子应该用连接词连接例 :Salmon spend most of their adult lives in salt water, despite they return to their freshwater birthplaces to spawn and die. 分析 : 错, 应改为 though despite 是介词, 后面一般接名词作宾语, 而在句中它后面却跟着一个完整的句子, 所以改为连词 though 例 :Solar eclipses occur during the Moon's shadow sweeps across the face of the Earth. 分析 : 错, 应改为 when 或 as 介词不能引导条件状语从句, 根据题意改为从属连词 when 或 as 例 :Even many early leaders of the United States have provided

14 Page 14 of 21 names for towns, only George Washington is remembered in the name of a state. 分析 : 错, 应改为 Even though even 为副词, 不能引导从句, 根据题意, 改为引导让步状语从句的 Even though 六比较级和最高级比较级和最高级的出题非常有规则, 一共有 5 个出题方向, 并且每次考试必然考两个 ( 一 ) 比较级或最高级形式上的重复例 :The most easiest process for mining gold is panning, which involves using a circular dish with a small pocket at the bottom. 分析 : 错, 应改为 easiest easiest 本身已是最高级, 不必再用 most, 这是最高级形式上的重复 ( 二 ) 比较级和最高级之间的混用例 :The greenest and plentifulest leaves are the leaves of grasses. 分析 : 错, 应改为 most plentiful plentiful 是多音节形容词, 须在前面加 most 构成最高级例 :The more fearsome of all the animals in the Western Hemisphere is the grizzly bear. 分析 : 错, 应该用最高级 most, 含有介词 of, among, in 表示的范围状语使用最高级 ( 三 ) 比较词 than 的前面一定要有比较级改错题中, 通常会看见 than 前面有一个原级例 :Film directors can take far great liberties in dealing with concepts of time and space than stage directors can. 分析 : 错, 应改为 greater 根据后面有 than 一词可以判定前面的形容词用比较级形式, 注意 far, much 修饰比较级 ( 四 ) 在 as as 以及否定 not so as, not as as 的中间使用形容词原级 as sweeter as, 这是不对的, 应改为 as sweet as

15 Page 15 of 21 ( 五 )the 和比较级最高级的关系 1 比较级前面可以出现 the, 修饰后面的名词 the taller boy 2 副词的最高级加不加 the 均可以例 :lthough flies live longest in cool temperatures, it breed prolifically when temperatures are warm, food is abundant, and humidity is moderate. 分析 : 副词的最高级加不加 the 均可, 所以正确, 从从句的主语可以看出, 应该改为 they 3 形容词的最高级作定语前面必须使用 the, 如果不作定语的话, 加不加 the 均可以例 :Of all the Native mericans in the United States, the Navajos form largest group. 分析 : 错, 应改为 form the largest 形容词最高级前面要加定冠词陷阱 1, earliest, 有两种可能, 一种可能是 early 的最高级, 最早的语言,the earliest language 另一种可能作名词, 表示早期, 必须和时间的名词连用,earliest time, earliest ages, 表示很早的年代, 很早的时代, 也就是说, 如果以后碰上 earliest 后面加上 times, ages, 前面不用加 the 例 :The belief in fairies have existed from earliest times, and the literature of many countries includes tales of fairies and their relationship to humans. 分析 : 错, 应改为 has existed 主语是单数名词 the belief, 而不是复数名词 fairies, 故谓语动词是单数形式 earliest times 表示表示很早的时代是正确的陷阱 2, 如果最高级前面有所有格的话, 不用加 the 例如 :my best friends 例 :Salt Lake ity, Utah's capital and largest city, is industrial and banking center. 分析 : 错, 应改为 is an industrial center center 为可数名词, 它的修饰词前面应有不定冠词 Utah's largest city, 题目中其实是省略了 Utah's 例 :Faults in the Earth's crust are most evidently in sedimentary formations, where they interrupt previously continuous layers.

16 Page 16 of 21 分析 : 错,are 的表语必须用 evident, 为什么不加 the, 因为作表语, 而不是定语七平行结构改错题考的最多的一个方向便是平行结构 ( 一 ) 对等连接词一共有三类连接平行结构的词单一式 : and, or,but 相关式 : both and, not but, either or, neither nor the same as;as as, not so as, not as as such as, so that.. too to, from to, from until, between and, not only but also(also 可以省略 ),Not only + 主谓,also not only but also(also 可以省略 )+as well, 短语式 : as well as rather than ( 而不是 ) other than ( 除之外 ) instead of ( 代替 ) 考试的方式往往是搭配中有一个单词是对的, 另一个单词却不对例 :John lived in New York since 1960 to 1975, but he is now living in etroit. 分析 : 错, 应改为 from 从某年到某年要用 from to 这个表达法, 不能用 since to 例 :Even as he wrote copiously on so diverse topics as education,politics,and religion,lewis Mumford remained active in city and regional planning. 分析 : 错, 改为 such diverse topics as, 出现 as, 往往要注意前面一半 ( 二 ) 平行的内容第一引导词性的平行, 词性的平行本质上是语法作用的平行例 :Photoperiodism is the functional or behavioral response of an organism to changes in duration of daily, seasonally,

17 Page 17 of 21 or yearly periods of light and darkness. 分析 : 错, 应改为 seasonal 在 daily, seasonally 和 yearly 三个并列的词中,daily 和 yearly 是形容词, seasonally 是副词, 故改为形容词 seasonal, 共同修饰名词 periods, 三个形容词的平行, 词性平行第二名词单复数的平行但是如果既有可数名词, 又有不可数名词, 可以不平行例 :The main advertising media include direct mail, radio, television, magazines, and newspaper. 分析 : 错, 应改为 newspapers newspaper 为可数名词, 在没有任何前置修饰语的情况下一般用复数形式, 并且和前面的 magazine 平行, 而 mail, radio, television 则是不可数名词例 :The anadian province of Newfoundland has a rocky coast, a moisture climate, and probably the best cod-fishing areas in the world. 分析 : 海岸气候只有一个, 但是钓鱼的地方可以有许多个, 所以也是不可数名词和名词复数的平行 ; 因此没有错, 错改为 have 第三时态的平行例 :The poet Marianne Moore was initially associated with the imagist movement, but later develops her own thyme patterns and verse forms. 分析 : 错, 应改为 developed 句中前半部分谓语为过去时, 与之并列的谓语也应用过去时例 :ecause the papaya grows readily from seed, spread from its home in entral merica and now grows throughout the tropics. () to be () it () the () its 分析 : 正确答案为 () 空格前是原因状语从句, 后面紧接着是谓语动词, 空格处明显缺主句主语四个选项中只有能单独作主语注意 spread 是过去式, 没有数的变化, 因为这一动作明显发生在过去时间 spread 和 grows 为什么时态可以不平行呢? 原来它在 entral merica 的家乡传播, 现在在整个地方传播,now 只修饰后面的 grow 例 :ucks have been domesticated for many centuries ---- commercially for their meat and eggs. () raised () and are raised () raised as () are raised

18 Page 18 of 21 分析 : 正确答案为空格前是一个完整的句子, 根据一个空格处如再出现谓语动词一定要有连词这一原则, 为惟一符合条件的选项故选 () 第四排列位置的平行例 :---the surface of metal, but also weakens it. () Not only does rust corrode () Not only rust corrodes () Rust, which not only corrodes () Rust not only corrodes 分析 : 正确答案为从 but also 放在动词前可知,not only 也须置于动词前, 故选中的 Not only 位置放错了, 使句子缺主句, 故排除对于 not only, but also 的用法有以下几种 : 1 主语 +not only + 谓语,but also+ 谓语, 正确 ; 例如上面例题中的第四个选项 2 Not only + 主谓,but also+ 主谓, 正确 3 Not only + 主语 + 谓语,but also+ 谓语, 错误八词序的颠倒词序的颠倒一般只考一道,90% 的情况集中于下面三个出题方向 ( 一 ) 先说形容词, 再说名词例 :The Medal of Honor is the highest award military for courage that can be given to any individual in the United States. 分析 : 错, 军事的荣誉是 military award 而不是 award military, 单个形容词修饰名词时一般放在被修饰词的前面 ( 二 ) 副词 + 形容词 + 名词例 :ertain types of computers work properly only in environments with controlled precisely temperatures. 分析 : 错, 应改为 precisely controlled, 精确的被控制的温度 controlled 为过去分词用作形容词, 修饰它的副词应放在其前面, 它自己则要紧挨着被修饰的名词 ( 三 ) 主语系动词, 系动词 + 表语例 :uring the 1600's skilled shoemakers scarce were

19 Page 19 of 21 in what is now the United States. 分析 : 错, 应改为 were scarce 表语应该放在系动词后面所有的系动词分为三大类 : 第一种 : 表示保持某种状态, is, remain, keep, stay, lie, exit( 表示位于 ) 第二种, 从一种状态转变到另一种状态 become, turn, grow, get (It is getting warmer and warmer) 第三种, 感官动词 seem( 好像是 ) look( 看起来好像是 ) feel, sound, appear, smell, taste enough 修饰形容词或副词时, 一般放在形容词或副词后面例 : The eruptions of Mt. St. Helens were enough severe to cause numerous deaths. 分析 : 错, 应改为 sever enough severe 是形容词, enough 放在 severe 后面九词性的混用词汇量的掌握对词性的使用非常重要, 但是如果对出题方向有更好的把握, 将会弥补词汇量的不足 ( 一 ) 做表语时形容词和副词的混用做表语永远用形容词, 绝对不能用副词 ; 例 :Giant pandas, which inhabit restricted areas of high mountain bamboo forests, are rarely today and when they are in captivity they breed poorly. 分析 : 错, 应改为 are rare rarely 为副词, 不能作表语, 故改为形容词 rare( 罕见的, 稀少的 ) ( 二 ) 加宾语时名词和动名词的混用后面加宾语当然要用动名词例 :Tilling means preparation the soil to plant the seeds

20 Page 20 of 21 and keeping the soil in the best condition to help the crop grow until it is ready3 for harvesting. 分析 : 错, 应改为 preparing preparation 为名词, 后面不能接宾语, 改为动名词 preparing 后既能接宾语, 又与后面的 keeping 构成并列关系例 :Langston Hughes, a prolific writer of the 1920's, was concerned with the depicting the experience of urban lack people in the United States. 分析 : 错, 应改为 depicting depicting 在此为动名词, 作介词宾语时不加冠词注意此处还可以改为 the depiction of, 但略显累赘, 因为后面还有 of 结构 The + 动名词, 这个动名词其实就变为了名词 ( 三 ) 表示时间时, 状语从句连接词和近义的介词混用表示时间有两种可能, 一种是状语从句, 由 when and while 引导, 后面加句子另一种是由介词引导, 如 during, 后面加名词, 考试中往往就利用这个特点, 总是给出相反的情况例 :alloon observations for military intelligence were made while the merican ivil War. 分析 : 错, 应改为 during while 是从属连词或并列连词, 后面接句子, 后面是名词短语时, 应改为介词 during 例 :Some of the most celebrated publicity stunts while the history of radio were associated with Gracie llen. 分析 : 错, 应改为 in while 为连词, 后面要求接从句, 而句中显然没有从句, 故根据题意改为介词 in ( 四 ) 对等连接词和近义的副词混用连接平行结构的词叫做对等连接词, 但是如果出现 else, also, instead 等副词把这些结构连接起来行不行呢? 当然不行例 :Mary Mcowell shared Jane ddam's interest in social work also was a loyal supporter of the League of Nations.

21 Page 21 of 21 分析 : 错, 应改为 and also 是副词, 不能连接并列的谓语动词, 故改为并列连词 and 例 :Paper is strong under tension instead crumples easily under the stress of compression. 分析 : 错, 应改为 but; 题目意思是在拉力的作用下很强, 而在压力的作用下容易起皱 ;instead, 副词不能连接两个动词并列,but 的对等连接词和 and, or 的用法是一样的 ( 五 ) 表示人的名词和表示事物的词混用例 :n editor is customarily a brief newspaper or magazine article that gives personal comments on current events. 分析 : 错, 应改为 editorial editor 的意思是编辑, 根据题意改为名词 editorial( 社论 ) 例 :For centuries, music have played acoustical guitars, which produce sound from the vibration of the strings. 分析 : 错, 应改为 musicians music 是抽象名词, 意为音乐, 不能表示复数要领显然应改为 musicians( 音乐家 ) ( 六 ) 只能用副词 + 数量词 + 名词 ; 不能用形容词 nearly two hundred students, 这里 nearly 修饰的是 200; two hundred diligent students
