  第1章 主谓一致



  1) 语法形式上要一致,即单复数形式与谓语要一致。

  2) 意义上要一致,即主语意义上的单复数要与谓语的单复数形式一致。

  3) 就近原则,即谓语动词的单复形式取决于最靠近它的词语,


  There is much water in the thermos.


  Ten thousand tons of coal were produced last year.



  Readingand writing are very important. 读写很重要。

  注意:当主语由and连结时,如果它表示一个单一的概念,即指同一人或同一物时,谓语动词用单数,and 此时连接的两个词前只有一个冠词。例如:

  The ironand steel industry is very important to our life. 钢铁工业对我们的生活有重要意义。


  The Leaguesecretary and monitor ___ asked to make a speech at the meeting.

  A. is  B. was C. are  D. were

  答案B. 注:先从时态上考虑。这是过去发生的事情应用过去时,先排除A.,C。本题易误选D,因为The League secretary and monitor 好象是两个人,但仔细辨别,monitor 前没有the,在英语中,当一人兼数职时只在第一个职务前加定冠词。后面的职务用and 相连。这样本题主语为一个人,所以应选B。

  2. 主谓一致中的靠近原则

  1)当therebe 句型的主语是一系列事物时,谓语应与最邻近的主语保持一致。例如:

  There is a pen, a knife and several books on the desk. 桌上有一支笔、一把小刀和几本书。

  There are twenty boy-students and twenty-threegirl-students in the class.班上有二十个男孩,二十三个女孩。

  2)当either… or… 与neither… nor,连接两个主语时,谓语动词与最邻近的主语保持一致。如果句子是由here, there引导,而主语又不止一个时,谓语通常也和最邻近的主语一致。例如:

  Either you or she is to go. 不是你去,就是她去。

  Here is a pen, a few envelops and some paper for you. 给你笔、信封和纸。


  当主语有with, together with, like, except, but, no lessthan, as well as 等词组成的短语时,谓语动词与前面的主语部分一致。例如:

  Theteacher together with some students is visiting the factory. 教师和一些学生在参观工厂。

  He as wellas I wants to go boating.他和我想去划船。

  4. 谓语需用单数的情况

  1)代词each以及由every,some, no, any等构成的复合代词作主语时,或主语中含有each, every时, 谓语需用单数。例如:

  Eachof us has a tape-recorder. 我们每人都有录音机。

  There is something wrong with my watch. 我的表坏了。


  TheArabian Night is a book known to lovers of English. 《天方夜谭》是英语爱好者熟悉的一本书。


  Three weeks was allowed for making the necessary preparations. 用三个星期来做准备。

  Tenyuan is enough. 十元够了。


  1)代词what, which, who, none, some,any, more, most, all等词的单复数由其指代的词的单复数决定。例如:

  All is right. 一切顺利。

  All are present. 人都到齐了。

  2)集体名词作主语时,谓语的数要根据主语的意思来决定。如family, audience, crew,crowd, class, company, committee等词后,谓语动词用复数形式时强调这个集体中的各个成员,用单数时强调该集体的整体。例如:

  His family isn't very large. 他家成员不多。

  His family are music lovers. 他家个个都是音乐爱好者。

  但集合名词people, police, cattle, poultry等在任何情况下都用复数形式。例如:

  Are there any police around? 附近有警察吗?

  3)有些名词,如variety, number, population, proportion, majority 等有时看作单数,有时看作复数。例如:

  Anumber of +名词复数+复数动词。

  Thenumber of +名词复数+单数动词。

  Anumber of books have lent out.

  Themajority of the students like English.


  1)用halfof, most of, none of, heaps of, lots of, plenty of 等引起主语时,谓语动词通常与of后面的名词/代词保持一致。例如:

  Mostof his money is spent on books. 他大部分的钱化在书上了。

  Most of the students are taking an active part insports. 大部分学生积极参与体育运动。

  2)用a portion of, a seriesof, a pile of, a panel of 等引起主语时,谓语动词通常用单数。例如: A series of accidents has been reported. 媒体报道了一连串的事故。

  A pile of lots was set beside the hearth. 炉边有一堆木柴。

  3)如many a 或 more than one 所修饰的短语作主语时,谓语动词多用单数形式。但由more than… of 作主语时,动词应与其后的名词或代词保持一致。例如:

  Manya person has read the novel. 许多人读过这本书。

  Morethan 60 percent of the students are from the city.百分之六十多的学生来自这个城市。

  比较:rise, fall, happen是不及物动词;raise, seat是及物动词。


  2) 不能用于被动语态的及物动词或动词短语,如fit, have, hold,marry, own, wish, cost, notice, watch agree with, arrive at / in, shake handswith, succeed in, suffer from, happen to, take part in, walk into, belong to等。例如:

  4)特殊结构:make sb. heard / understood (使别人能听见/理解自己)等。例如:

  I domiss you. 我确实想你。

  Onlywhen we begin our college life do we realize the importance of English. 进了大学以后,我们才认识到英语的重要性。

  说明: 引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。


  ----Do you like Beijing? --你喜欢北京吗?

  ----Yes, I do. --是的,喜欢。(do用作代动词,代替like Beijing.)

  Heknows how to drive a car, doesn't he? 他知道如何开车,对吧?

  4. 助动词shall和will的用法


  I shall study harder at English.  我将更加努力地学习英语。

  He will go to Shanghai.  他要去上海。




  He shallcome. 他必须来。(shall有命令的意味。)

  He willcome. 他要来。(will只与动词原形构成一般将来时。)

  5.助动词should, would的用法


  Itelephoned him yesterday to ask what I should do next week. 我昨天给他打电话,问他我下周干什么。

  比较:"What shall I do next week?" I asked. "我下周干什么?"我问道。


  2) would也无词义,是will的过去形式,与动词原形构成过去将来时,用于第二、第三人称。例如:

  He saidhe would come.  他说他要来。

  比较:"I will go," he said. 他说:"我要去那儿。"变成间接引语,就成了He said he would come。原来的will变成would,go变成了come.。

  6. 短语动词


  Turn off the radio. 把收音机关上。(turnoff是短语动词)




  3)动词+副词+介词,如:look forward to。构成短语动词的副词和介词都统称为小品词
