主谓一致
谓语动词的数应和主语的人称和数保持一致,这叫主谓一致。在判定一个句子主谓是否一致时,要遵循下列三个原则:语法一致、意义一致和就近一致。“语法一致”就是从语法形式上取得一致,即主语为单数形式,谓语动词也采用单数形式;主语为复数形式,谓语动词亦为复数形式。“意义一致”就是从意义着眼来处理主谓语一致的问题。主语形式为单数,但意义为复数,谓语动词依意义而定,也采用复数形式。“就近一致”是指谓语动词的人称和数往往和与其最近的主语保持一致。

典例剖析
1. People sit uncomfortably on plastic chairs, looking through old magazines, ________ have been read hundreds of times previously.
all of them B. each of which
C. all of which D. each of them
答案:C
解析:考查非限制性定语从句关系词,主谓一致。句意:人们不舒服地坐在塑料椅子上翻阅着旧杂志,这些杂志以前已经被读过几百次了。A. all of them 它们全都;B. each of which它们中每一个;C. all of which 它们全部都;D. each of them它们中每一个。该空需要使用关系代词which代替先行词magazines引导非限制性定语从句;根据空后have可知,主语应为复数意义,应使用all。故选C项。
2. Not only the students but also the teacher _____ a great interest in playing football.
A. show B. shows C. to show D. showing
答案:B
解析:考查主谓一致。句意:不仅学生们而且老师都对踢足球表现出极大的兴趣。not only...but also 连接两个成分作主语,遵循就近原则,其后谓语动词与就近的主语保持一致。teacher为单数,谓语动词用第三人称单数形式。故选B。
3. It's clear that neither he nor his parents _____ the plan put forward at the family meeting.
agrees to B. are for
C. is in favor of D. agree on
答案:B
解析:考查主谓一致。neither...nor连接两个并列的主语时,谓语采用就近原则,所以谓语的数应由his parents来决定。因为his parents是复数,所以agrees to和is in favor of都可以排除,agree on 的主语必须是达成共识的人们或者单位。故选B。
4. A professor and a writer _____present at the meeting.
A. was B. is C. were D. had been
答案:C
解析:考查主谓一致。句意:一位教授和一位作家出席了会议。这里主语用and连接起来,因为每个名词前都有冠词,所以这是两个人,故排除A、B;过去完成时是相对的时态,整句话没有过去式所以不可能用过去完成时。故选C。
5. Neither your sister nor mine _____the good news. Let's tell them.
A. know B. knows C. knew D. known
答案:B
解析:考查主谓一致和一般现在时。句意:你妹妹和我妹妹都不知道这个好消息。让我们告诉她们。根据“Let's tell them.”可知,此处是指现在的客观事实,所以应用一般现在时。“neither...nor...”的主谓一致使用“就近原则”,mine是指“我的妹妹”,为第三人称单数。故选B。
6. The factory used 65% of the raw materials, the rest of which ___________ saved for other purposes.
A. is B. are C. was D. were
答案:D
解析:the rest of +主语, 谓语动词的单复数形式视主语而定。定语从句the rest of which...中的主语是which, 指代前文的the raw materials, 是个复数形式, 故谓语动词用复数形式, 且主句的时态为过去时, 所以从句的时态也为过去时。句意: 工厂用了65%的原材料, 剩下的保存下来另作他用。故选D。
7. Nowadays, cycling, along with jogging and swimming, ___________ as one of the best all-round forms of exercise.
regard B. is regarded
C. are regarded D. regards
答案:B
解析:句意:现在,骑自行车、慢跑和游泳被认为是最全面的锻炼方式之一。根据动词短语regard...as...(把……看做……)和句意,确定应该用被动语态,排除A和D;由介词短语along with 连接的三个名词作主语,谓语动词应该就前一致,即用单数,排除C。故选B。

A. The number of; is B. The number of; are
C. A number of; are D. A number of; is
答案:A
