GMAT语法中的一致性问题是比较高频的考点,也常有考生因为对这个问题不够重视而引发各类错误。下面是小编为大家整理收集的关于GMAT语法SC中常见的8大一致性问题考点,仅供大家参考。
1. 主语谓语单复数一致
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 us 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形式。如:What I bought were three English books. / What I say and do is (are) helpful to you.
2. 合成主语用复数
由连接词and或both …… and连接起来的合成主语后面,要用复数形式的谓语动词。
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:(1)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. (2)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 (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. 短语不影响单复数形式
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 and children, has come to China. / Nobody but Jim and Mike was on the playground. / She, like you and Tom, is very tall.
4. 复合不定代词的单复数判定
either, 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:(1)在口语中当either或neither后跟有“of+复数名词(或代词)”作主语时,其谓语动词也可用复数。如:Neither of the texts is (are) interesting. (2)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. 关系代词做主语的单复数一致
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 working hard. / He is the only one of my friends who is working hard.
6. 集体名词单复数使用区别
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. 数量词构成短语注意单复数用法
由“a 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+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”,主语是number,谓语用单数。
8. 倒装句中动词单复数问题
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.
