主语和谓语的一样(Agreement between subject and verb)⒈Definition: 主语要和谓语在人称和数上保持一样叫主谓一样。

⒉主谓一样包括三个原则：语法一样原则、意义一样原则和就近一样原则。

㈠语法一样原则：指用作主语的名词词组的中心词和谓语动词在单复数形式上的一样。

⑴介词短语with, as well as, including, except, except for, but, together, besides, rather than, along with, together with 等修饰主语时，谓语动词的数的形式及介词前面的名词或代词的人称和数保持一样。

e.g. I, along with my parents, am a football fan.The girl as well as boys likes playing basketball.⑵由each 和every 修饰的名词以及由every-, any-, some-, no- 构成的复合代词都当作单数，谓语动词用单数。

e.g. Every hour and every minute is important.Every boy and every girl enjoys the holiday.Someone is waiting for you.Everyone is here.Everything is ready.⑶动名词（短语），不定式（短语）和从句作主语，谓语动词用单数形式。

e.g. To see is to believe.Walking on the moon is very difficult.What he said is wrong.注：ⅰ. 在用形式主语it 的句中和在用it 作主语的强调句中，谓语动词总用单数。

e.g. It isn’t obvious who will be the best.It was he who taught us English last year.ⅱ. what 引导的主语从句，谓语一般用单数，但假如表示复数意义时谓语动词要用复数。

（完整版）高考英语专题复习主谓一致（附答案）.doc高考英语专题复习主谓一致（附答案）I.考点分析一、概述主谓一致是指句子成分之间或词语之间在人称、性、数等方面的一致关系。

处理主谓一致一般应遵循以下三条原则：1.语法一致，即在语法形式上取得一致。

例如，主语为单数形式，谓语动词也为单数形式；主语为复数形式，谓语动词也采取复数形式。

a. The number of errors was surprising.b. Julia and her twin sister naturally look a lot alike.2.意义一致，即从意义着眼处理一致关系。

a. The crowd were fighting for their lives. (单形名词主语要求复数谓语动词，下划线部分表示一个整体中的成员 )b. Five minutes is enough. ( 复数名词单数谓语动词，下划线部分表示一个数目)3.邻近原则，即指谓语动词的形式与邻近的名词一致。

a. A man of abilities are needed（.动词 are 不与主语 a man一致，而与其邻近的复形名词a bilities 形式上一致。

二、主谓一致注意要点：1.当名词词组中心词为表示度量、时间等复数名词时，往往可根据意义一致的原则，把这些复数名词看作一个整体，谓语动词采取单数形式。

a. The dollars is not enough.b. Three months passes in no time at all on the ranch.如果明显地指一个个个体，则要根据语法一致地原则，谓语动词用复数形式。

a. There are two sliver dollars in each of the stockings.2.如果名词词组中心词是all, most, half, the last, the rest, the remainder等词组时，其主谓关系一般遵循意义一致的原则：如所指为复数意义，谓语动词用复数形式；如所指为单数意义，则谓语动词用单数形式。

What is your opinion？In this sentence，the subjectclause takes the form of “What is your opinion”，and the predicate is “is”. The object clause is “that surfing the Internet is of great help to their study” and “it is a waste of time and energy”.

主谓一致A、谓语用单数的情况1、以单数名词或代词、动词不定式、动名词短语或从句作主语时。

例：The boy is clever enough to study maths well.To work hard is necessary.Reading aloud is very important in learning a foreign language.Whether she comes or not is of no matter.2、由and连接的并列单数主语的前边如果分别有each, every, 或no修饰时，其谓语要用单数形式。

例：In our country every boy and every girl has the right to education.No teacher and no student is going to take part in such a boring game.3、主语是单数，其后尽管有as well as, no less than, rather than, more than, but, except, besides, with, along with, together with, like, including, in addition to等起连接作用的词语带其他名词，谓语动词仍用单数。

本句时一个主语从句，it作形式主语，真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.，主语从句中又有一个主语从句，且此主语从句中缺少主语，所以用what引导。

What引导名词性从句作主语的主谓⼀致问题What引导名词性从句作主语的主谓⼀致问题英语中,当what引导的名词性从句作主语时, 主句的谓语动词（⼀般为be的某种形式）有时⽤单数形式，有时⼜⽤复数形式。

如何处理这种主谓⼀致关系？下⾯就对这⼀问题作了些归纳与整理。

1．在what引导名词性从句作主语时的SVC (即“主语+谓语动词+表语”)结构中,如果主语补语是单数名词或不可数名词,主句的谓语动词采取单数形式。

例如： What the boy wants is a toy car. What the country needs most is wise leadership.2．当主句的表语是复数名词时,主句的谓语动词通常⽤复数形式。

例如： What we need are good doctors. What was real to him were the details of his life. 但在美国英语中主句的谓语动词也可以⽤单数形式： Perhaps what is most surprising is the tears. What we getting is old answers to old questions.3. 当从句的谓语动词和主句的表语均为复数形式时,主句的谓语动词⼀般要⽤复数形式。

3.例如： What have surfaced are similes, viscous streams of them. What are often regarded as poisonous fungi are sometimes safely edible.4．当主句的表语是形容词时,谓语动词通常⽤单数形式。

例如： What is beautiful is not always good. What I have to tell you is very simple. 但当从句的what修饰复数名词时，主句的谓语动词就⽤复数形式： What friends she has are clever.5．当主句的表语是介词短语时,谓语动词⽤单数形式。

在英语句子里，谓语受主语支配，其动词在人称和数上必须和主语保持一致，这就叫主谓一致。

主谓一致大致可归纳为三个原则，即语法一致、逻辑意义一致和就近一致。

语法一致原则语法一致就是谓语动词和主语在单、复数形式上保持一致。

1．单数名词、代词、动词不定式(短语)、动名词(短语)或主语从句作主语时，谓语动词一般用单数形式；主语为复数时，谓语动词用复数形式。

►To study French well is not easy.学好法语不容易。

►What he said is very important for us all.他说的话对我们大家很重要。

【注意】由what引导的主语从句，后面的谓语动词多数情况用单数形式；但若表语是复数或what从句是一个带有复数意义的并列结构时，主句的谓语动词用复数形式。

►What I bought were three Chinese books.我买的是三本中文书。

►What I say and do are helpful to you.我所说的、所做的都对你有帮助。

2．由连接词and或both...and...连接起来的合成主语后面，谓语动词要用复数形式。

►Both she and he are middle school students.他和她都是中学生。

【注意】(1)若and所连接的两个词是指同一个人或事(物)时，主语后面的谓语动词就应用单数形式。

►The writer and artist has come.那个兼有作家和艺术家双重身份的人来了。

►To go to bed early and to rise early is a good habit.早睡早起是个好习惯。

(2)由and连接的并列单数主语前如果有no, each, every, more than a(an), many a(an)修饰时，其谓语动词要用单数形式。

►No boy and no girl likes it.男孩和女孩没有一个喜欢这个的。
