【语法回顾】 主谓一致 1. 语法一致的原则 2. 意义一致的原则 3. 邻近一致的原则 谓语受主语支配，须和主语在人称和数上保持一致，这叫做主谓一致。主谓一致一般遵循三条原则：语法一致原则，意义一致原则和就近一致原则。 在英语中，谓语动词必须和主语在人称和数上同主语保持一致，叫做主谓一致。通常采用下列三个原则来处理，即：语法形式一致的原则、逻辑意义一致的原则、就近（或毗邻）一致的原则。 一、语法形式一致的原则，即在语法形式上取得一致。如：主语为单数形式，谓语动词用单数；主语为复数形式，谓语动词也采用复数形式。但须注意下列几种情况： 1.以单数名词或代词、动词不定式短语、动名词短语或从句作主语时，谓语动词用单数。 例如： Much land has been deserted in this area in the past few years.在过去的几年中，这个地区的许多土地已经沙化。 To start smoking is quite easy, but to give it up needs courage.开始吸烟很容易，但是要戒烟却需要勇气。 Reading English newspapers is a good way of improving you English. 阅读英文报纸是提高你英语水平的好方法。 What you need most is to have a good sleep.你所需要的就是好好睡一觉。 How you can get there is a problem. 你怎么到那儿去还是个问题。 [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 。例如： What I bought were three English books.我买的是三本英语书。 What I say and do is (are) helpful for you.我所说的和做的对你是有帮助的。 2、由and 或both...and来连接并列主语时，谓语用复数。例如： Swimming and walking are good exercises.游泳和散步都是好运动。 He and I were classmates when we were at college.他和我在上大学时是同学。 Both John and Ann have got pen-friends.约翰和安都有笔友。 Both Zhou Lan and Yang Pei like sports.周兰和杨蓓都爱好体育。 [注意]1）但是，并列主语如果表示同一个人、同一事物或同一概念时，谓语动词用单数形式（这时and后的名词前没有冠词）。例如： The manager and secretary was absent at the meeting.经理兼书记没有出席会议。 The manager and the secretary are busy now.经理和书记现在都很忙。 Their teacher and friend is Mr. Li.他们的老师和朋友是李先生。 2)由and连接的并列单数主语前如果分别被no, each, every或many a ，more than one修饰时，其谓语动词用单数形式。 例如： In our country every boy and every girl has the right to receive education.在我们国家里，每个男孩和女孩都有权利受教育。 Each man and each woman is asked to help. 每个男士和妇女都被请来帮忙。 Many a student is having practice in that factory. 许多学生正在那家工厂实习。 More than one student is interested in the book.不止一个学生对这本书感兴趣。 [注意] 在“more than one＋单数名词”作主语时，若在There be句型中，亦可用复数。 如： There is/are more than one man here. 这儿不止一个人。 3、如果主语是单数，尽管后面跟有(together) with, as well as, like, but, except, besides，including, no less than, rather than ,as much as，more than，along with in addition to等介词短语，其谓语动词仍用单数形式；若主语为复数，则谓语动词也用复数。例如： An English teacher together with some students has climbed to the top of the mountain.一位英语老师和几个学生已经爬到了山顶。 Mary as well as her friends likes this painting.玛丽和她的朋友都喜欢这幅画。 No one except my close friends knows anything about this matter.除了我的亲密朋友谁也不知道这件事。
