主谓一致 主谓一致的定义英语句子中，主语的“人称”和“数” 要限制、决定谓语动词的形式变化，这 就叫“主谓一致”关系。它通常依据三 项原则： 1）语法一致； 2）意义一致； 3）就近一致。【语法一致原则】 I .主语的“人称”决定谓语动词的形式 e.g. I love / She loves music . 我/ 她爱好音乐。 Are your mother a worker ? (误)你母亲是工人吗？Is your mother a worker ?(正)（主语your mother 是单数第三人称）II .主语的“数”决定谓语动词的形式1.“不可数名词、可数名词单数、单数代词、不定式（短语）、动名词（短 语）”或“从句”等作主语，用单数谓语形式。e.g. The work is important . 这项工作重要。 To serve the country is our duty . 为祖国服务是我们的义务。 How and why he left was a sad story . 他离开的经过和原因是一段伤心的经历 。2. 复数的名词、代词一般接复数谓语形式。 e.g. The children are taken good care of.孩子们得到很好的照料。 They have gone to Chengdu . 他们去成都了。 III. 以“and ”或“both and”连接的并列主语： 1.通常作复数用 。e.g. Plastics and rubber never rot . 塑料和橡胶从不腐烂。 What he says and what he does do not agree. 他言行不一致。 Both Tom and I are fond of medicine. 我和汤姆都喜欢医学。2. 如果并列主语指的是“同一个”人（事 、物、抽象概念），作单数用。e.g. The worker and writer has come . 这位工人作家来了。 A cart and horse was seen in the distance . 远处能看见有一套马车。 Truth and honesty is the best policy . 真诚是最好的策略。3. “and”前、后的单数词语都有 “each,every ,many ,a ,no”等修饰时，仍 作单数用。e.g. Every boy and every girl enjoys equal rights here.这里每个男孩和每个女孩都享 有平等权益。 No teacher and no student is excused from taking part in the activity .没有哪个 教师或学生可以免于参加这项活动。 . 主语前、后加表“数、量”等的修饰语时： 1. a）“many a + 单名 ”接单数谓语：“a good (great ) many + 复名”接复数谓语。 e.g. Many a fine man has died for it. 许多优秀战士为此献出了生命。 A great many parents were present at the meeting . 许多家长出席了会议。 b）“a / an + 单名+ or two “ 大多接单数 谓语： “one or two + 复名“接复数谓语。 e.g. Only a word or two is (are )needed. 只需说一两句。 One or two reasons were suggested.提出一两条理由。c）“a / an + 单名+ and a half“常接单数 谓语；“one and a half +复名”多接复数 谓语。e.g. A year and a half has passed. 一年半已过去了。 One and a half tons of rice are sold. 已卖了一吨半大米。d） “more than one + 单名“大多接单数 谓语。e.g. More than one person was (were )absent . 不止一个人缺席。 “more + 复名+ than one “接复数谓语。 e.g. More students than one have been there.不止一个学生去过那儿。“more than two (three,)+复名 “ 接 复数谓语。e.g.More than one hundred students have attended the concert. 不止一百名学生听了这场音乐会。 2. 主语前加表示“单位、度量”的短语如“a kind (sort / type / form /pair /cup /glass /piece / load / block / box / handful / quantity / ton / meter / )of”等时，表示“单位、度量”的这个名词的单复数决定谓语形式。e.g.a）There is only a small quantity of paper (books ) left. 只剩下少量的纸（书）了。 Large quantities of water are needed. 需要大量的水。b） This kind of apple is sweet. 这种苹果甜。 This kind of apples is (are) sweet. （ 大多依 kind ，作单数用 ） These kinds of apple(s) are sweet. （总作复数用） 但:Apples of this kind are sweet. （总作复数用） 3. 主语后接“with”等构成的短语修饰成 分时, 谓语仍须与这类短语前的“主语”一致。可构成这类短语的有： with ,along with ,together with ,as well as , but , besides , except ,added to , including , like ,no less than , rather than, more than 等。e.g. A woman with two children has come . 一位妇女带着两个孩子来了。 I as well as they am ready to help you . 不仅他们，我也愿帮助你。 4. “one of + 复数名词+ 定语从句“： 1）定语从句的先行词通常是这个“复数名 词”，因此从句的谓语用复数形式。 e.g. This is one of the best novels that have appeared this year . 这是今年出版的最佳小说之一。（关系词 “that”代“novels”）He was one of the boys who were praised. 他是受表扬的男孩之一。 2）若“one”前加“this, the ,the only ”等时， 定语从句的关系词指代one，作从句主语 时，接单数谓语。e.g. He was the only one of the boys who was praised .他是男孩中唯一受到表扬的。 (关系词who 代 the only one )【意义一致原则（Notional Concord）】 I. 集合名词作主语时： 1. 有些通常作复数用(不变词形) 。如： “people , police , cattle (牛，牲口)， folk , youth , militia (民兵)”，等。e.g. The police have caught the murderer.警方已捕获凶手。2. 有些指“整体”时作单数，指其中的“成 员”时作复数（不变词形）。如 “army , audience(听众),class ,club （俱乐部） ,company(公司), committee(委员会) ,crew ,crowd ,staff(员工) ,family ,public ,government ,group ,party ,union ,couple ,population ,team .“等。e.g.Our family is a happy one . 我们有个幸 福的家庭。 The family are early risers . 这家人都起 得早。 The public are (is )requested not to litter . 请公众不要乱扔废弃物。 但上述集合名词也可有复数形式。如： families , two classes .等。有些变复数形式 后意义不同。如：peoples多个民族。 youths男青年。 folks亲友。II. 代词作主语时： 1. 不定代词“each, one, much, (a) little, either, neither, another, the other(+单名)“ 等常作单数用。它们所修饰的主语也作单 数。e.g. Each of the girls (=Each girl) has a new hat. 每个女孩都有顶新帽子。 Neither plan suits me.
