语法一致原则是指主语和谓语在语法形式上必须一致，即谓语动词的单复数形式由主语的单复数形式决定。这一原则主要适用于以下几种情况： 1．不可数名词或可数名词单数形式作主语时，谓语动词用单数形式；可数名词的复数形式作主语时，谓语动词用复数形式。 ◆These toys are designed for children under three years old. 这些玩具是为三岁以下的儿童设计的。 ◆Every part is carefully checked before they are put together. 组装之前，每一个部件都要仔细检查。 2．复合不定代词anyone, anything, someone, somebody, something, everyone, everybody, everything, nobody, nothing在句中作主语时，谓语动词用单数形式。 ◆Everything is in a complete mess, which drives people crazy. 所有的事情都毫无头绪，让人发疯。 ◆Somebody in the know has told me Tom is going to resign. 有知情者已告诉我汤姆要辞职了。 3．当each, either, neither作主语或主语由each, either, every, neither, no所修饰时，谓语动词用单数形式。 ◆Neither of the books is of any use to me. 这两本书对我都没有用。 ◆Each of the houses is painted a different colour. 每所房子都漆成了不同的颜色。 4．单个的动词不定式、v.­ing(短语)或主语从句作主语时，谓语动词一般用单数形式。 ◆When they could finish the task is not known yet. 他们何时能完成这项任务还是未知。 ◆Listening to music makes me relaxed after a busy day. 听音乐使我在一天的忙碌之后得到放松。 5．由as well as, along with, together with, with, rather than, no less than, but, except, besides, in addition to, like, including等连接两个部分作主语时，谓语动词与前面的主语保持一致。 ◆Jack, along with his friends, goes skating every Saturday. 每个星期六，杰克都会和他的朋友们一起去滑冰。 ◆The teacher as well as the students likes the painting. 老师和学生们都喜欢这幅画。 6．“many a(n) (许多)/more than one (不止一个)＋可数名词单数”作主语时，尽管从意义上看是复数，但谓语动词仍用单数形式。 ◆Many a boy likes playing basketball. 很多男孩都喜欢打篮球。 ◆More than one person is against the proposal. 不止一个人反对这个提议。 7．“one of＋可数名词复数”后跟定语从句时，从句中的谓语动词常用复数形式；而“the (only) one of＋可数名词复数”后跟定语从句时，从句中的谓语动词用单数形式。 ◆He is one of the students who have been to Beijing. 他是那些去过北京的学生中的一个。 ◆He is the only one of the students who has been to Beijing. 他是那些学生中唯一一个去过北京的。 8．在“It＋is/was＋被强调部分＋that/who ...”结构中，如被强调部分是主语，that/who后的谓语与被强调部分的人称、数保持一致。 ◆It is they who have worked there for five years. 是他们在那里工作了五年。 [即时演练1]——单句语法填空 (1)He showed me how his medical instruments were (be) used.

(4)Barbara is easy to recognize as she's the only one of the women who wears (wear) evening dress. (5)It is reported that many a new house is being built (build) at present in the disaster area. 二、意义一致原则 意义一致原则是指从意义着眼来解决主谓一致问题。主语所表达的单复数概念并不总是根据主语的形式，有时要根据它所表达的意义来确定。这一原则主要适用于以下几种情况： 1．and连接的两个单数名词作主语时，谓语动词一般用复数形式。但如果and 所连接的两个单数名词指的是同一个人、同一件事或表示整体概念时，则谓语动词用单数形式，这时and后面的名词前不加冠词。 ◆The secretary and the manager were present as the meeting. 秘书和经理都出席了会议。 ◆War and peace is a constant theme in history. 战争与和平是历史的永恒主题。 ◆A poet and artist is coming to speak to us about Chinese literature and painting tomorrow afternoon. 明天下午一个诗人兼艺术家将来给我们做关于中国文学和绘画的演讲。 2．all, none, some, any 等不定代词作主语时，谓语动词的数根据其指代的内容确定。 ◆None of the books is/are easy enough for the junior students. 这些书太难，不适合初中学生。 ◆None is more qualified for the task than him. 没有人比他更适合执行这项任务了。 ◆All who have studied this question have come to the same conclusion. 所有研究过这个问题的人都得出了同样的结论。 ◆Such poets as Shakespeare are widely read, of whose works, however, some are difficult to understand. 像莎士比亚这类诗人读者众多，不过他们的一些作品难以理解。 3．“all/most/half/some/the rest ...＋of＋名词/代词”或“分数/百分数＋名词/代词”作主语时，若名词或代词表示单数概念或抽象概念，谓语动词用单数形式；若表示复数概念，谓语动词用复数形式。 ◆About two thirds of the Earth's surface is covered by the sea. 地球表面大约三分之二被海洋覆盖。 ◆Some of the books about investment fund have been published recently. 最近出版了一些关于投资基金方面的书。 4．表示时间、距离、金额、重量等的复数名词作主语时常被当作一个整体来看待，谓语动词常用单数形式，但为了强调数量之多，也可用复数形式。 ◆Fifty dollars was a large sum for me at that time. 那时50美元对我来说是一大笔钱。 ◆Twenty kilometers is quite a long distance. 20千米是相当长的一段距离。 5．“the＋形容词/分词”表示一类人时，谓语动词用复数形式。 ◆The old are taken good care of in the old people's home. 在这家养老院，老年人被照顾得很好。 6．a number of ...(许多……)作主语时，谓语动词用复数形式；the number of ...(……的数量)作主语时，谓语动词用单数形式。 ◆A number of famous people were invited to the party last night. 昨晚许多名人受邀参加这个聚会。 ◆The number of students in our class is 32. 我们班的学生人数是32。 [即时演练2]——单句语法填空 The number of medical schools reached 18 in the early 1990s and has remained (remain) around that level ever since.

(4)One­third of the country is covered with trees and the majority of the citizens are old people.(be) (5)All we need is (be) a small piece of land where we can plant various kinds of fruit trees throughout the growing seasons of the year. 三、就近原则 就近原则是指谓语动词的人称和数往往与其最近的主语保持一致。这一原则主要适用于以下几种情况： 1．either ...or..., ...or ..., neither ...nor ..., not only ...but also ..., not ...but ...等连接的名词或代词作主语时，谓语动词的人称和数由最靠近谓语动词的名词或代词决定。 ◆Either Jack or you are to blame for the fault. 要么杰克要么你应为这个过失负责。 ◆Not only the students but also the teacher wants to go climbing. 不仅学生们想去爬山，老师也想去。 2．there be句型中的be动词应与离其最近的名词或代词在人称和数上保持一致。 ◆There are two books, a pen and many pencils on the desk. 桌上有两本书、一支钢笔和许多铅笔。 ◆There is a pen, two books and many pencils on the desk. 桌上有一支钢笔、两本书和许多铅笔。 [即时演练3]——单句语法填空 (1)They often run at high speeds, which may put our lives in danger.And there are (be) traffic jams, too.
