全国专业四级英语填空题常考结构

1、全国专业四级英语填空题常考结构2十三、make 结构 make 结构即为：make +sth.( 宾语)+possible+(宾语补足语)共有三种形式：make it possible+to domake it possible+that引导的从句 makepossible sth ( 这个sth 一定很长，它后面有一个后置定语)做题技巧：如果 possible 后面有to do 或者that引导的定语从句，中间一定有it如果possible 后面有名词，中间一定没有 it例 1 : X-rays are able to pass through objects and thus make d

2、etails thatare otherwise impossible to observe . (A) it visible(B) visibly(C)visible(D) they are visible 分析：此题考动词 make 的一种用法，visible 后面有名词，因此中间不能有it,选择C；可以看到空格后that引导的是定语从句，visible是宾语补足语，宾语补足语的存在是因为宾语太长了，details是宾语。例 2 : Using many symbols makes to put a large amount of information ona single map.(A

3、) possible(B) it possible(C) it is possible(D) that possible 分析：从四个选项可以判断出本题考 make的一种惯用法。首先排除 明显的错误选项：C为句子，却没有与主句相连的连词，D中that后面应有主语并构成结构完整的从句。由于后面是动词不定式，因此 possible前面一定有it, it作形式宾语，故B正确。十四、the morethe more 结构这个结构的意思是越.越”，结构一共有三条规则：1. the more后面的名词必须使用冠词或者所有格，新题专门考这条规则2. the more后面的谓语如果是 be动词的话，可以省略，

4、例如上面的例题3.第二个the more 后面可以使用倒装，而第一个后面却不行 the more, the more其实是原因状语从句，前面是原因，后面是结果，倒装句中必须是主句倒装，从句绝对不能够倒装。例 1 : The stronger_magnet, the greater the number of lines of magneticforce.(A) of(B) the(C) is the(D) is of the分析：本题显然考查the more the more”结构，the more后面的名词必须使用冠词或者所有格，因此只能选择 B例 2 : The less the surf

5、ace of the ground yields to the weight of the body ofa runner,to the body.(A) the stress it is greater(B) greater isthe stress(C) greater stress is(D) the greater the stress 分析： 正确答案为D。此题考the more the more 句型，只有 D符合这一句型的要求，故选 D。十五、表示结果的伴随状语结构主谓宾完整的句子后面，如果出现两个词，thereby 或者thus,那么这两个词后面必须使用现在分词，表示从而怎么样

6、”的意思，这便是表示结果的伴随状语结构。但是必须注意并不是thus后面就是加doing ,必须是前面一个完整的句子才对。例 1 : A microphone enables a soft tone to beamplified ,A B thusmaking it possible the gentleC renditions of romantic love songs in alarge hall.D 分析：Possible 后面有名词，那么 it应该去掉，thus后面表示结果的伴随状语从句，表示从而使得歌曲演唱成为可能。例 2 : The Smithsonian Institution

7、preserves more than sixty-five million items of scientific, historical, or artistic interest,winning the popular title,“attic of the nation. (A) however(B) thus(C) and(D) moreover 分析：逗号前面是个完整的句子，逗号后面是现在分词短语作状语表示结果。四个选项中只有 thus 一词可直接放在现在分词前面，故选 Bo thus副词，修饰分词 winning, 伴随状语例 3 : Snow aids farmers by k

8、eeping heat in the lower ground levels, thereby from freezing.(A) to save the seeds(B) saving theseeds(C)which saves the seeds(D) the seeds saved 分析：thereby 和to有意思重复，所以不能够选择 (A),后面应该跟现在分词，答案为 B十六、形容词最高级省略结构The crane is the tallest bird of the wading birds.最高级后面的名词与范围名词重复，可以省略，句子变为 The crane is the t

9、allest of the wading birds.(A) the tallest(B) the(D) which the tallest is 分析：空空格处明显缺作表语的名词或名词短语。例 1 : The crane is of the wading birds.tallest that is(C) which is the tallest格前是主语和谓语，空格后是of引导的介词短语, 四个选项中只有(A)使句子结构完整，语义清楚，故选( A)。例 2 ： . Cows are said to be the least intelligently ofABCdomestic animal

10、s.D 分析：改为形容词，intelligent , intelligently为副词，不能作表语。十七、规则动词过去分词作定语结构这里的规则动词指的是过去式和过去分词一样，导致考生看不出句子结构， 比如： program, programmed, programmed因此判断这个词是过去式还是过去分词就显得比较重要：第一步：从逻辑上判断这个动作是主动还是被动第二步：如果是被动的话，做谓语前面一定有系动词be例 1 : Wupatki National Monument in Arizona features structures built of(A) That the(B) Inred s

11、andstone by ancestors of the Hopi people. 然缺定冠词the修饰主语，故选 D。A中that引导主语从句，使整个句子变成从句而无主theAround theThe 分析：空格后是结构完整的句子，空格处显句，B、C构成介词短语，使句子缺主语，故排除。句子中的built是过去分词。例 2 : Antibodies by small, round cells called lymphocytes and plasmacells.(A) to be made(B) making(C) made(D) aremade 分析：空格前为名词作主语，空格后是介词by引导

12、的动作执行者，called是过去分词作定语，所以句子缺谓语，故选 D。A、B、C均为非谓语动词，故排除。例 3 : Automatons programmed to perform a given task the flexibility andadaptability of human beings.(A) without(B) lack(C) minus(D) not having 分析：programmed在句中是过去分词作名词后置修饰语，空格处缺谓语动词。四个选择答案中只有( B)是可作谓语的动词，故选( B)。 B , programmed 是一个定语，而不是谓语，机器人被编制程序，

13、所以是过去分词，而不是谓语动词十八、逻辑主语结构在一个完整的句子前面出现现在分词、过去分词、或者介词短语，那么这个句子的主语是前面这三种结构逻辑上的主语。例 1 ： Having been served lunch,.(A) the problem was discussed bythe members of the committee(B) the committee members discussed theproblem(C) it was discussed by the committee members the problem(D) a discussion of the prob

14、lem was make by the members of the committee分析：Having been served lunch指被招待了午饭，那么只可能是委员会的成员被招待，而不可能是问题，所以选择B例 2 : was not incorporated as a city until almost two centuries later, in(D) Settled by the1834.(A) Settling Brooklyn, the Dutch(B) The Dutch settledBrooklyn(C) Brooklyn was settled by the Dut

15、chBrooklyn 表示人或者Dutch, Brooklyn 分析：空格后面是谓语和状语，空格处缺主语。Dutch表示地方做主语，但是从 as a city 可知，主语不是人名，而是地名，由此首先排除Ao B、C均是句子，不合要求。 D符合句法和题意。例 3 : At thirteen at a district school near her home, and when she wasfifteen , she saw her first article in print.(A) the first teaching position thatMary Jane Hawes had(B)

16、 the teaching position was Mary Jane Hawes first(C) when Mary Jane Hawes had her first teaching position(D) Mary JaneHawes had her first teaching position分析：从并列连词 and 可知，第一个逗号前是一个完整的句子，空格处缺主谓结构，而且主语是一个人名。四个选项中只有D以人名作主语，故选D。例 4 : Even at low levels,.(A) the nervous system has produceddetrimental effe

17、cts by lead(B) leads detrimental effects are producingthe nervous system(C) lead produces detrimental effects on the nervoussystem(D) the detrimental effects produced by lead on the nervoussystem分析：空格前为介词短语状语，空格处缺一个完整的句子。A、B结构上似乎完整，但意思不清，D不是完整的句子，故选 Co例 5 : The chorus plays a large part in any orato

18、rio, linkingA BC areas were sung by soloists with segments of choral music.D 分析：应该把D中的were去掉十九、复合宾语结构有些及物动词+宾语后意思表达不完整，需要再加形容词或者名词来补充说明宾语被叫做不完全及物动词，该形容词或者名词叫做宾语补足语。宾语加补足语叫做We played复合宾语。当宾语和宾补由主动语态变为被动语态，分别变为主语和主补。soccer. We called him Bob. Bob在这里作宾语补足语 He was called Bob. Bob在这里作主语补足语下面列出了一些经常要求使用宾补

19、的动词make, consider, call, elect, appoint,例： We appoint him monitor.We elected him president.例 1 : Poodles were once used as retrievers in duck hunting , but theAmerican Kennel Club does not consider them because they are nowprimarily kept as pets.(A) where sporting dogs(B) sporting dogswhen sporting

20、dogs(D) they are sportingdogs 分析： 选择 B, them 是宾语，sporting dogs 宾补二十、It结构一、强调句型 It is +强调部分+that + 其余部分这个句型需要注意几点：强调部分+其余部分是一个完整的句子；强调部分可以强调主 语、宾语和状语，不能强调谓语和定语；强调人使用who或者that,其他的只能用that （即 使是时间和地点），who和that绝对不能省略如果原句是过去时态，强调句型使用it was.,例如：原句：Ann bought these books last year.强调宾语：It was these books th

21、atAnn bought last year.强调状语：It was last year that Ann bought these books.二、形式主语 It is + 名词/形容词+ to do/that 引导的句子to do/that 引导的句子是 真正的主语，it是形式主语，这是为了避免头重脚轻。例 1 : It is the interaction between people , rather thanA Bthe events that occur in their lives , that areC the main focus of socialpsychology.D

22、分析：Rather than是插入语，主句是强调句型，it isthOi语是 interaction, 所以是 is例 2 : an increasing international exchange ofeducational films.(A) It is(B) There is(C) Though there is(D) Although it is分析：缺少主谓，选择B, it用在句子的句首，只可能作强调句型或者形式主语。空格后是一个名词短语，只有 B与之构成完整的句子。A语义不完整，C、D则使整个句子成了让步从句而缺主句，故都可排除。二H一、which引导的定语从句结构which是关

23、系代词，which后面应该加缺主语或者宾语的句子，在这个句子中，which要作成分，作主语或者宾语in which+ 完整的句子which在定语从句中作in的宾语，所以不能作后面句子的主语名词+of which+ 谓语动词of which 来修饰名词，名词在定语从句中作主语，所以后面直接跟谓语动词例 1 ： In blank verse of ten syllables, five of which are accented.(A)line consists of each(B) consists of each line(C) each line consistsit consists of each line 分析：空格前后均为介词词组，逗号后为非限定性定语从句， 空格处缺主句主谓成分。A单数名词line前没有限定词，而且语义不清，B没有主语，D中it指代不明，所以选 Co five of which are accented表示其中五个要被重读，of which 修(five, 十个中的五个例 2 : The spiral threads of spiders web have a sticky substance onthem insects.(A) traps(B) trap its(C) which
