A.not make B.not to make C.not making D.do not make
在解這道題之前,我們先來探討以下三個(gè)問題:
一、對稱原則及其在高考試題中的應(yīng)用
并列連詞and.or,but,while等連接的前后兩個(gè)部分有某種對稱性,或曰前后的詞形要一致。
比如說前面是動(dòng)詞,后面也要是動(dòng)詞;前面是過去式,后面也要是過去式;前面是主動(dòng)語態(tài),后面也要用主動(dòng)語態(tài),如此等等。掌握這種對稱原則,對解單項(xiàng)填空和短文改錯(cuò)有很大用處。下面舉數(shù)例高考試題佐證。
例1:My brother ______while he ______his bicycle and hurt himself.(MET'89)
A.fell,was riding B.fell were riding
C.had fallen,rode D.had fallen,was riding
[分析]答案A.根據(jù)對稱原則,and連接的并列謂語時(shí)態(tài)要一致,后面hurt是過去式,前面也應(yīng)用過去式fell.while從句表示fell動(dòng)作發(fā)生的時(shí)間是“在騎自行車時(shí)”,應(yīng)用過去進(jìn)行時(shí)。
例2:On saturday afternoon,Mr Green went to the market,_____some bananas and
visited her 高考 cousin.(MET'91)
A.boughtB.buying C.to buyD.buy
[分析]答案A.此題是含and連接的三個(gè)并列謂語,第一,三個(gè)動(dòng)詞用了過去式(went,visited),第二個(gè)必然要用過去式。
例3:Playing football not only makes up grow up tall and strong but also give us a sense of fair play and team spirit.(NMET'98)
[分析] not only … but also … 在這里連接并列謂語,根據(jù)對稱原則,前面用的是一般現(xiàn)在時(shí)單數(shù)第三人稱形式makes,后面一個(gè)應(yīng)是一般現(xiàn)在時(shí)單數(shù)第三人稱,故這行g(shù)ive應(yīng)改為gives.
例4:They eager to know everything about 93.______China and asked me lots of questions.(NMET'96)
[分析]在這道改錯(cuò)題中這句話的主語是they,and連接的并列謂語第二個(gè)是過去式asked,根據(jù)對稱原則,第一個(gè)也應(yīng)是過去式。但eager是形容詞,前面須加be的過去形式were.
