??所謂語法一致性就是謂語動詞和主語在單、復數形式上保持一致。這個考點光從字面上來看貌似十分簡單,但涉及到具體題目中卻往往會成為突破關鍵。具體來說,在GMAT語法中有關一致性的具體考點主要有以下8種:
1。 主語謂語單復數一致
以單數名詞或代詞、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形式;主語為復數時,謂語動詞用復數形式。
??
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情況用單數形式,但若表語是復數或what從句是一個帶有復數意義的并列結構時,主句的謂語動詞用復數形式。
??如:What I bought were three English books。 / What I say and do is (are) helpful to you。
2。 合成主語用復數
由連接詞and或both …… and連接起來的合成主語后面,要用復數形式的謂語動詞。
??
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形式。如:The writer and artist has come。 (2)由and連接的并列單數主語前如果分別有no, each, every more than a (an) , many a (an)修飾時,其謂語動詞要用單數形式。
??如:Every student and every teacher was in the room。 / No boy and no girl likes it。
3。 短語不影響單復數形式
主語為單數名詞或代詞,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,謂語動詞仍用單數形式;若主語為復數,謂語用復數形式。
??
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。 復合不定代詞的單復數判定
either, neither, each, every 或no +單數名詞和由some, any, no, every構成的復合不定代詞,都作單數看待。
??
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+復數名詞(或代詞)”作主語時,其謂語動詞也可用復數。
??如:Neither of the texts is (are) interesting。 (2)若none of后面的名詞是不可數名詞,它的謂語動詞就要用單數;若它后面的名詞是復數,它的謂語動詞用單數或復數都可以。如:None of us has (have) been to America。
??
5。 關系代詞做主語的單復數一致
在定語從句時,關系代詞that, who, which等作主語時,其謂語動詞的數應與句中先行詞的數一致。
如:He is one of my friends who are working hard。
?? / He is the only one of my friends who is working hard。
6。 集體名詞單復數使用區別
如果集體名詞指的是整個集體,它的謂語動詞用單數;如果它指集體的成員,其謂語動詞就用復數形式。
??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。如:The police are looking for the lost child。
7。 數量詞構成短語注意單復數用法
由“a lot of, lots of, plenty of, the rest of, the majority of + 名詞”構成的短語以及由“分數或百分數+名詞”構成的短語作主語,其謂語動詞的數要根據短語中后面名詞的數而定。
??
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”,作定語修飾復數名詞,謂語用復數;the number of“……的數量”,主語是number,謂語用單數。
8。 倒裝句中動詞單復數問題
在倒裝句中,謂語動詞的數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。
假如考生能夠對上文提到的這8種涉及到GMAT語法一致性的具體問題有充分了解和掌握,那么想要迅速解決一些語法難題或者縮小選項范圍排除大部分錯誤選項就不會太過困難了。
