1、语法复习二、主谓一致在英语句子里,谓语受主语支配,其动词必须和主语在人称和数上保持一致,这就叫主谓一致。 寻其规律,大致可归纳为三个原则,即语法一致、逻辑意义一致和就近一致原则。(-)语法一致原则:语法上一致就是谓语动词和主语在单、复数形式上保持一致。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,谓语动词一般用单 数形式;主语为复数时,谓语动词用复数形式。如:His father is working on the farm. / To study English well is not easy. / What he said is very important for u
2、s all. / The children were in the classroom two hours ago. / Reading in the sun is bad for your eyes.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 whal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形式。如:What I bought were three English books. / What I say and do is (are) helpful to you.2、由连接词and或bothand连接起来的合成主语后面,要用复数形式的
3、谓语动词。如: Lucy and Lily are twins. / She and I are classmates. / The boy and the girl were surprised when they heard the news. / Both she and he are Young Pioneers.注意: 若and所连接的两个词是指同一个人或物时,它后面的谓语动词就应用单数形式。 如:The writer and artist has come.; /由and连接的并列单数主语前如果分别有no, each, every more than a (an), many a
4、(an)修饰时,其谓语动词要用单数形式。如:Every student and every teacher was in the room. / No boy and no girl likes it.3、主语为单数名词或代词,尽管后面跟有* with, together with, except, but, like, as well as, rather than, more than, no less than, besides, including等引起的短语,谓语动词仍用单数形式;若主语为 复数,谓语用复数形式。如:Mr Green, together with his wife a
5、nd children, has come to China. / Nobody but Jim and Mike was on the playground. / She, like you and Tom, is very tall.4either, neither, each, every或no +单数名词和由some, any, no, every构成的复合不定代词, 都作单数看待。如:Each of us has a new book. / Everything around us is matter.注意 在口语中当either或neither后跟有“of+复数名词(或代词)”作主
6、语时,其谓语 动词也可用复数。如:Neither of the texts is (are) interesting. 若none of后面的名词是不可数 名词,它的谓语动词就要用单数;若它后面的名词是复数,它的谓语动词用单数或复数都可以。 如:None of us has (have) been to America.5、在定语从句时,关系代词that, who, which等作主语时,其谓语动词的数应与句中先行词 的数一致。如:He is one of my friends who are workhig hard. / He is the only one of my friends w
7、ho is working hard.6、如果集体名词指的是整个集体,它的谓语动词用单数;如果它指集体的成员,其谓语动 词就用复数形式。这些词有 family, class, crowd, committee, population, audience 等。如:Class Four is on the third floor. / Class Four are unable to agree upon a monitor.注意:people, police, cattle 等名词一般都用作复数。如:The police are looking for the lost child.7、由“a
8、lot of, lots of, plenty of, the rest of, the majority of + 名词”构成的短语以及由“分数 或百分数十名词”构成的短语作主语,其谓语动词的数要根据短语中后面名词的数而定。如:There are a lot of people in the classroom. / The rest of the lecture is wonderful. / 50% of the students in our class are girls.注意:a number of “许多”,作定语修饰复数名词,谓语用复数;the number of ”的数量”,
9、 主语是number,谓语用单数。8、在倒装句中,谓语动词的数应与其后的主语一致。如:There comes the bus./ On the wall are many pictures. / Such is the result. / Such are the facts.(二)逻辑意义一致原则:逻辑意义一致就是谓语动词的数必须和主语的意义一致(因有时 主语形式为单数,但意义为复数;有时形式为复数,但意义为单数)。1、what, who, which, any, more, all等代词可以是单数,也可是复数,主要靠意思来决定。如: Which is your bag? / Which a
10、re your bags? / All is going well. / All have gone to Beijing.2、表示“时间、重量、长度、价值”等的名词的复数作主语时,谓语动词通常用单数形式, 这是由于作主语的名词在概念上是一个整体,如:Thirty minutes is enough for the work.3、若英语是书名、片名、格言、剧名、报名、国名等的复数形式,其谓语动词通常用单数 形式。如:The Arabian Nightss an interesting story-book.4、表数量的短语“one and a half后接复数名词作主语时,其谓语动词可用单数形
11、式(也 可用复数。如:One and a half apples is (are) left on the table.5、算式中表示数目(字)的主语通常作单数看待,其谓语动词采用单数形式。如:Twelve plus eight is twenty. / Fifty-six divided by eight is seven.6、一些学科名词是以-ic.s 结尾,如:mathematics, politics, physics 以及 news, works 等, 都属于形式上是复数的名词,实际意义为单数名词,它们作主语时,其谓语动词要用单数形式。 如:The paper works was b
12、uilt in 1990. /1 think physics isn 7 easy to study.7a trousers, glasses, clothes, shoes,等词作主语时,谓语用复数,但如果这些名词前有a (the) pair of 等量词修饰时,谓语动词用单数。如:My glasses are broken. / The pair of shoes under the bed is his.8、“定冠词the +形容词或分词”,表示某一类人时,动词用复数。(三)就近一致原则:在英语句子中,有时谓语动词的人称和数与最近的主语保持一致。1、当两个主语由 either . or,
13、 neither . nor, whether . or not only . but also 连接时,谓 语动词和邻近的主语一致。如:Either the teacher or the students are our friends. / Neither they nor he is wholly right. / Is neither he nor they wholly right?2. there be句型be动词单复数取决于其后的主语。如果其后是由and连接的两个主语,则 应与靠近的那个主语保持一致。如:There are two chairs and a desk in the
14、 room.注意Here引导的句子用法同上。练习:主谓一致1.1, who your friend, will try my best to help you with your English.C.areC.hasD.beD.haveA.amB.isThe rich not always happy.A. areB.isNeither Tom nor Jack and I his students.A. areB.amC.isD.wasMary as well as her sisters Chinese in China.A. are studyingB. have studied C.
