主谓一致问题

主谓一致是指主语与谓语在数上要一致。把握主谓一致问题，考生主要解决的是对不同结构的主语单复数的认定，进而选择适当的谓语。

1.主谓一致常出现在主谓倒装结构中。如：

Just outside the ruins is a magnificent building surrounded by tall trees.

Although a great number of houses in that area are still in need of repair, there has been improvement in the facilities.

2.主语与谓语之间有定语从句或其他结构修饰，所以距离较远，考生易误认主语。如：

The amount of pressure which the materials are subject to affects the quality of the products.

3.关系代词做主语的定语从句中，谓语的数要与先行词一致。如：

Despite much research, there are still certain elements in the life cycle of the insect that are not fully understood.

There are many valuable services which the public are willing to pay for, but which do not bring a return in money to the community.

4.动名词短语、不定式短语、名词性从句做主语，谓语用单数。如：

Buying clothes is often a time-consuming job because those clothes that a person likes are rarely the ones that fit him or her.

To understand the situation completely requires more thought than has been given thus far.

5.主语带有(together/along)with, such as, as well as, accompanied by, including, rather than 等附加成分, 谓语的数不受附加成分的影响。如：

The president of the college, together with the deans, is planning a conference for the purpose of laying down certain regulations.

6.表示时间、距离、金额、重量、面积、体积、容积等度量的名词短语做主语时，谓语用单数。

7.某些固定结构中谓语的数：

a great many + 可数名词复数 谓语用复数

many a + 可数名词单数 谓语用单数

a number of +可数名词复数 谓语用复数

the number of +可数名词复数 谓语用单数

the majority of +可数名词复数 谓语用复数

each/every +可数名词单数 谓语用单数

neither/either of +可数名词复数 谓语用单数

more than one +可数名词单数 谓语用单数

one and a half +可数名词复数 谓语用单数

the greater part of

a large proportion of

50% of

谓语的数与of后面的名词一致

one third of

the rest of

倒装结构

倒装是指句子成分不是按主语在前、谓语在后的正常语序排列，而是将谓语或谓语的一部分移到主语之前。倒装是一种修辞手段，目的是为了强调。倒装分为部分倒装和全部倒装，考试多为部分倒装。考生应掌握什么情况下需要倒装。

1.下列否定词及含有否定意义的词组修饰状语时，若置于句首，句子的主谓要部分倒装

never, no, neither, not only, hardly, scarcely, little, seldom, rarely, not until, nowhere, at no time, on no account, in no respect, in no sense, by no means, in no way, no longer, no less, no more, no sooner than, under no circumstances, in vain, still less。如：

Not only is its direct attack on their discipline, it bypasses the essence of what sociologists focus on.

Under no circumstances should we do anything that will benefit ourselves but harm the interests of the state.

2.以only修饰状语开头的句子，句子的主谓要部分倒装

only then, only at that time, only once, only in this way, only with, only through, only by, only when, only after, only because。如：

Only when you have obtained sufficient data can you come to a sound conclusion.

3.以下列副词或短语开头的句子，句子的主谓要部分倒装

often, so, well, to such a degree, to such an extent, to such extremes, to such a point，many a time。如：

So involved with their computers do the children become that leaders at summer computer camps often have to force them to break for sports and games.

4.以下列副词开头的句子，句子的主谓要全部倒装

(1)出于修辞需要，表示方向的副词：out, down, in, up, away, on。如：

Down jumped the burglar from the tenth floor when he heard someone shouted at him.

(2)出于习惯用法：here, there, now, thus, hence, then。如：

Now is your turn. There goes the bell.

(3)有时主语较长，为了使句子平衡，避免头重脚轻，主谓要全部倒装。这种情况多出现在主系表结构中。如：

Less important than ever is developing a meaningful philosophy of life.

In between these two extremes are those people who agree with the jury system as a whole, but feel that some changes need to be implemented to improve its effectiveness.

5.让步从句的倒装

(1)as引导让步状语从句，必须采用倒装结构，但不是主谓倒装，而是将被强调的内容置于句首。如：

Much as I have traveled, I have never seen anyone to equal her, in thoroughness, whatever the job.

(2)出现在句型be+主语+其他, come what may中。如：

While it’s true that we all need a career, preferably a profitable one, it is equally true that our civilization has accumulated an incredible amount of knowledge—be it scientific or artistic.

The business of each day, be it selling goods or shipping them, went quite smoothly.

Come what may, I’ll be on your side.

6.比较从句的倒装

as, than引导的比较从句中，如果主语是名词短语且较长，经常采用倒装结构(不倒装也可以)。注意：这种结构主语一般为名词，如果是代词则不倒装。如：

Hydrogen burns much more cleanly than do other fuels and is easy to produce.

Today’s electric cars cannot go as fast as gasoline-driven vehicles because the battery does not offer the same amount of energy as does gasoline combustion.

Reading is to the mind as is exercise to the body.

(1)如果谓语动词是单个实义动词，倒装时需根据人称和时态加助动词do。如：

Little did we expect that he would fulfill his task so rapidly.

(2)考生要广义理解“句首”的概念，注意从句的句首和并列分句的句首均为句首。如：

Suddenly, Gallup’s name was on everyone’s lips; not only was he the prophet of the moment, but it was generally believed that he had founded a new and most important method of prediction.

复合句——形容词性(定语)从句

定语从句的测试重点：选择正确的关系代词或关系副词。

切记：关系代词/副词一定要在从句中充当某种成分，即主语、宾语、表语或定语。指人时用who(做主语)、whom(做宾语)、whose(做定语)；指物时用which或that；指时间用when；指地点用where；指原因用why。此外还要注意如下几个问题：

1.尤其要注意whose的用法

whose在从句中做定语，修饰名词。所以，如果关系代词后面紧接的是名词，且关系代词又不在从句中做主语或宾语，那么，这个关系代词就应该是whose。如：

Of course developing a system for helping students whose needs are out of the ordinary had been a necessary step in helping those students get into the world of public education.

It is perhaps not an exaggeration to say that we shall soon be trusting our health, wealth and happiness to elements with whose very names the general public are unfamiliar.

2.介词 + which的用法

如果从句中主宾成分齐全，考生便可考虑关系代词是否在从句中做状语，而状语通常用介词短语充当，于是可以得知，关系代词前面应有介词，再分析所给的选项，根据与名词的搭配作出正确选择。如：

Children are best served when schools contribute to shaping the solid foundation on which their future will be built.

However, the batteries from which they(electric vehicles) draw energy usually contain harmful chemicals, which become pollutants when the batteries are disposed of.

We are not conscious of the extent to which work provides the psychological satisfaction that can make the difference between a full and an empty life.

3.非限定性定语从句前面有逗号标志，按汉语习惯通常翻译成两个句子

切记：与汉语不同的是，英语中两个句子之间一般说来不能用逗号断开，而要用适当的连词或关系代词使它们形成从属或并列关系。据此可判断出逗号后面一句应由起连接作用的词开头。注意：有时关系代词前面还有其他附加成分。如：

Biologists believe that rainforests are the home of perhaps half the world’s biotic species, about five-sixth of which have not yet been described and named.

There are two spare rooms in the building, neither of which has been provided with modern facilities.

4.as 与which用作关系代词的区别

(1)as与the same, such, so, as等关联使用。如：

As the forest goes, so goes its animal life.

(2)as和which都可以引导非限定性定语从句，但as在句中的位置比较灵活，可出现在句首、句中、句末，而which只能出现在句末，尤其是当先行词是整个句子时。如：

As is true in all institutions, juries are capable of making mistakes.

As is generally accepted, economic growth is determined by the smooth development of production.

常见的这类结构有：

as has been said before, as has been mentioned above, as can be imagined, as is known to all, as has been announced, as can be seen from these figures, as might/could be expected, as is often the case, as has been pointed out,

as often happens, as will be shown等。

5.关系代词that与which用于引导定语从句的区别

(1)如果关系代词在从句中做宾语，用that, which都可以，而且可以省略；

(2)先行词是不定代词anything, nothing, little, all, everything时，关系代词用that；

(3)先行词由形容词最高级或序数词修饰或由next，last, only, very修饰时，用that；

(4)非限定性定语从句只能用which引导；

(5)关系代词前面如果有介词，只能用which。

6.but做关系代词，用于否定句，相当于who…not, that…not

这个结构的特点是主句中常有否定词或含有否定意义的词。如：

There are few teachers but know how to use a computer.

There is no complicated problem but can be solved by a computer.

复合句——名词性从句

一个句子起名词的作用，在句中做主语、宾语／介词宾语、表语、同位语，那么这个句子就是名词性从句。

1.what/whatever的用法

考生应把握：what是关系代词，它起着引导从句并在从句中担当一个成分这两个作用。如：

They lost their way in the forest, and what made matters worse was that night began to fall.

(what既引导主语从句又在从句中做主语)

Water will continue to be what it is today—next in importance to oxygen.

(what既引导表语从句又在从句中做表语)

2.whoever和whomever的区别

whoever和whomever相当于anyone who，用主格与宾格取决于其在从句中做主语还是做宾语。如：

They always give the vacant seats to whoever comes first.

(whoever在从句中做主语)

3.有关同位语从句的问题

(1)下列名词常用做同位语的先行词：

appeal, belief, conclusion, condition, conviction, doubt, evidence, fact, fear, feeling, ground(s),hope, idea, likelihood, message, news, opinion, order, plan, point, possibility, problem, promise,reply, proof, proposal, question, rumor, sign, story, suggestion, suspicion, theory, thought, truth, trouble, understanding, worry。如：

I have no doubt that he will overcome all his difficulties.

One sign that you are making progress in an art such as painting or photography is that you begin to realize how much there is to learn.

(2)引导词通常为that, 但有时因名词内容的需要，也可由whether及连接副词why, when, where,how引导。that不表示任何意义，其他词表示时间、地点、原因等。如：

The problem, where I will have my college education, at home or abroad, remains untouched.

The fact that she was a few minutes late is no reason for discharging her.

(3)同位语从句有时与先行词隔开，注意识别。如：

Evidence came up that specific speech sounds a

re recognized by babies as young as 6 months old.

(4)同位语从句与定语从句的区别：

● 从意义上看，同位语从句说明名词的具体内容，定语从句则对名词进行限定、修饰；

● 从结构上看，同位语从句的引导词不在从句中充当任何语法成分，定语从句的引导词在从句中必须充当一定的句子成分；

● 从先行词的词义特点看，同位语从句的先行词表达的是抽象内容，这类词数量有限，而定语从句的先行词则没有任何限制。

4.whether与if在引导名词性从句时的区别

(1)主语从句只能用whether引导；

(2)whether一般多用于宾语从句的肯定式，而if引导的从句可以有否定式；

(3)whether or not可以连在一起用，而if or not则不能，or not只能放在句末；

(4)whether可以引导介词宾语从句，if则不能；

(5)宾语从句提至谓语前面时，只能用whether引导；

(6)在question, ask后面一般只用whether，question的同位语从句也用whether引导；

(7)后接不定式时，只能用whether。

5.动词believe, expect, fancy, imagine, suppose, think后的宾语从句如为否定式，一般将否定词转移到主句谓语上，这一点在翻译时要注意与汉语表达的区别

复合句——副词性(状语)从句

副词在句中起状语作用，故如果起状语作用的部分为一个句子，那么该句便是副词性从句，也称状语从句。状语从句可细分为：时间、地点、条件、原因、让步、目的、结果、比较、方式等。

状语从句的测试重点为：考查考生对主从句之间逻辑意义关系的把握，看其是否能选择正确的从属连词。

对于常见的状语从句和从属连词的常规用法，本书不想赘述，只谈谈常见从属连

词的特殊用法并提醒考生应注意的地方。

1.条件状语从句的常考知识点
