在考研英語中,一些重點語法考察頻率很高,因此各位考生要予以重視。語法是英語學習的基礎,語法大關不過,閱讀、完型、翻譯和寫作都會有難度,就別提過線和拿高分了。下面小編為大家整理了2020考研英語語法大全之語法一致原則,供大家參考!
語法一致原則是指句子的主語和謂語在語法形式上一致,即通常情況下,謂語動詞的單復數(shù)形式依主語的單復數(shù)形式而定, 主語為單數(shù)形式時謂語動詞用單數(shù)形式, 主語為復數(shù)形式時謂語動詞也用復數(shù)形式。具體內(nèi)容請看下文。
1. 以單數(shù)名詞或代詞、動詞不定式短語、動名詞短語或從句作主語時,謂語動詞一般用單數(shù)形式;主語為復數(shù)時,謂語動詞用復數(shù)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引導的主語從句,后面的謂語動詞多數(shù)情況用單數(shù)形式,但若表語是復數(shù)或what從句是一個帶有復數(shù)意義的并列結構時,主句的謂語動詞用復數(shù)形式。如:What I bought were three English books. / What I say and do is (are) helpful to you.
2. 由連接詞and或both …… and連接起來的合成主語后面,要用復數(shù)形式的謂語動詞。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所連接的兩個詞是指同一個人或物時,它后面的謂語動詞就應用單數(shù)形式。如:The writer and artist has come. (2)由and連接的并列單數(shù)主語前如果分別有no, each, every more than a (an) , many a (an)修飾時,其謂語動詞要用單數(shù)形式。如:Every student and every teacher was in the room. / No boy and no girl likes it.
3. 主語為單數(shù)名詞或代詞,盡管后面跟有with, together with, except, but, like, as well as, rather than, more than, no less than, besides, including等引起的短語,謂語動詞仍用單數(shù)形式;若主語為復數(shù),謂語用復數(shù)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. either, neither, each, every 或no +單數(shù)名詞和由some, any, no, every構成的復合不定代詞,都作單數(shù)看待。如:Each of us has a new book. / Everything around us is matter.
注意:(1)在口語中當either或neither后跟有“of+復數(shù)名詞(或代詞)”作主語時,其謂語動詞也可用復數(shù)。如:Neither of the texts is (are) interesting. (2)若none of后面的名詞是不可數(shù)名詞,它的謂語動詞就要用單數(shù);若它后面的名詞是復數(shù),它的謂語動詞用單數(shù)或復數(shù)都可以。如:None of us has (have) been to America.
5. 在定語從句時,關系代詞that, who, which等作主語時,其謂語動詞的數(shù)應與句中先行詞的數(shù)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. 如果集體名詞指的是整個集體,它的謂語動詞用單數(shù);如果它指集體的成員,其謂語動詞就用復數(shù)形式。這些詞有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等名詞一般都用作復數(shù)。如:The police are looking for the lost child.
7. 由“a lot of, lots of, plenty of, the rest of, the majority of + 名詞”構成的短語以及由“分數(shù)或百分數(shù)+名詞”構成的短語作主語,其謂語動詞的數(shù)要根據(jù)短語中后面名詞的數(shù)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“許多”,作定語修飾復數(shù)名詞,謂語用復數(shù);the number of“……的數(shù)量”,主語是number,謂語用單數(shù)。
8. 在倒裝句中,謂語動詞的數(shù)應與其后的主語一致。如:There comes the bus. / On the wall are many pictures. / Such is the result. / Such are the facts.
