專升本大學(xué)英語語法說難也難,說簡(jiǎn)單也簡(jiǎn)單,英語語法的考察體現(xiàn)在英語考試的方方面面,今天好學(xué)校小編給大家分享一下浙江專升本英語語法虛擬語氣解析,有需要的考生可以看看。
一、?虛擬語氣在if?引導(dǎo)的條件句中的易錯(cuò)點(diǎn)?
?、賗f?my?lawyer?had?been?here?last?Saturday,?he?would?have?prevented?me?from?going.?
?、? if?you?had?studied?hard?at?school,?you?would?be?a?college?student?now.?
句子①②都是虛擬語氣在條件句中的使用,從句中都是假設(shè)過去的情況,所以用過去完成時(shí),但在主句中,句①依然指代過去的情況,謂語動(dòng)詞是would?have?done,而②中含有一個(gè)表示現(xiàn)在的時(shí)間狀語now,?這樣就必須將其理解為假設(shè)現(xiàn)在的情況,所以謂語動(dòng)詞必須為would/should/might+動(dòng)詞原形,學(xué)生在這一點(diǎn)上經(jīng)常會(huì)忽略now的存在,從而按句①的形式填寫答案。
二、虛擬語氣在名詞性從句中的用法?
1.在it?is?important?(strange,?natural,?necessary……)+that?句子或者It?is?decided?(ordered,suggested,?demanded,?advised……)+that句子中,主語從句中的謂語動(dòng)詞常用(should)+動(dòng)詞原形結(jié)構(gòu),表示某事“重要”、“必要”、“被決定”等?
例如:
it?is?important?that?everyone?(should?)?obey?the?rules?all?day?and?all?night.?
it?is?decided?that?the?meeting?(should)?be?held?tomorrow?afternoon.?
2.?suggest,?insist?后面指賓語從句時(shí)需注意的地方??
? ? ? ? ?suggest
?1)①suggest?當(dāng)“建議”“提出”講時(shí),其后賓語從句的謂語動(dòng)詞常用“should+動(dòng)詞原形”?例如:He?suggested?that?the?work?(should)?be?started?at?once?他建議立即動(dòng)工。?
類似的動(dòng)詞還有insist堅(jiān)持,demand要求,desire要求、請(qǐng)求,request請(qǐng)求,require要求、需要,order命令,propose建議,command命令,ask要求,advise建議,prefer寧愿等。
?這些動(dòng)詞變被動(dòng)語態(tài)(如:It?is?suggested?+?that主語從句)形式后,主語從句謂語動(dòng)詞仍用“(should)+動(dòng)詞原形”?這些動(dòng)詞變名詞(如suggestion)后,其后的表語從句和同位語從句中的謂語部分仍用“(should)+動(dòng)詞原形”?
②suggest?當(dāng)“提出(某看法),暗示,啟發(fā)”講時(shí),其后賓語從句的動(dòng)詞不用虛擬語氣。
?例如:The?police?suggested?that?the?thief?might?be?one?of?the?family?member?
警察局提出竊賊可能是一名家庭成員。?
insist
2)①insist作“堅(jiān)決要求…該…;堅(jiān)持認(rèn)為…定要…”講時(shí),其后賓語從句的謂語動(dòng)詞用“(should)+動(dòng)詞原形”?
例如:I?insisted?that?you?(should)?be?there?on?time.我堅(jiān)持認(rèn)為你應(yīng)該準(zhǔn)時(shí)到那里去?
②insist?作“堅(jiān)持(意見,看法);堅(jiān)持說,確信”講時(shí),其后從句不用虛擬語氣。
如:
He?suggested?(that)?he?heard?someone?in?the?next?room.?他堅(jiān)持說他聽到隔壁屋子里有人。?
