　　當(dāng)前正處于2017考研備戰(zhàn)的基礎(chǔ)復(fù)習(xí)期，英語(yǔ)一直是考研復(fù)習(xí)的難題。掌握知識(shí)點(diǎn)會(huì)運(yùn)用很重要。太奇MBA老師分享英語(yǔ)知識(shí)點(diǎn)，大家可以參考參考，更好的來完成考研目標(biāo)。

　　If I had time, I would go to the movies with you.

　　If we hadn’t made adequate preparations, the conference, wouldn’t have been so successful.

　　If it were to rain tomorrow, the game would be put off.

　　[提示]

　　1. 在非真實(shí)條件句中, 有時(shí)從句的動(dòng)詞所表示的動(dòng)作和主句的動(dòng)詞所表示的動(dòng)作并不同時(shí)發(fā)生,這樣的條件句中使用的虛似式稱為混合虛擬式。其構(gòu)成視具體情況而定。

　　If I had taken my raincoat when I came out this morning, I would not be wet now.

　　If I were you, I wouldn’t have missed the film last night.

　　2. 引導(dǎo)非真實(shí)條件從句的連詞if在正式文件中有時(shí)可以省去, were, had,

　　should等非行為動(dòng)詞這時(shí)應(yīng)提到從句句首。

　　If I were you, I wouldn’t feel sorry.

　　→Were I you, I wouldn’t feel sorry.

　　3. 有些句子從表層結(jié)構(gòu)上看無if引導(dǎo)的非真實(shí)條件句, 但從深層意思上看是存在的。這種情況下主句動(dòng)詞仍需用虛擬式。這類句子中常出現(xiàn)without(如果沒有), but for(要不是),otherwise(否則), but that(若不, 后接一從句)等詞或詞組。

　　But for your help, they couldn’t have succeeded.

　　要不是你的幫助, 他們就不會(huì)取得成功。

　　She wasn’t felling well. Otherwise she wouldn’t have left the meeting so early.

　　她感不舒服。不然她不會(huì)那么早就離開會(huì)場(chǎng)的。

　　二、虛擬式也可用于其他情況

　　1. 在it’s necessary (important, natural, essential, proposed, required,

　　suggested, impossible, strange) that…引導(dǎo)的真正的主語(yǔ)從句中動(dòng)詞應(yīng)用虛擬式,

　　表示必要、應(yīng)該、建議、要求、驚訝、不相信等意。

　　It’s necessary that we (should) set out at once.

　　It’s proposed that a committee (should) be set up to look into the matter.

　　It’s only natural that you should be nervous. 你感到緊張是很自然的。

　　The dentist suggested that she (should) come another day.

　　It is highly important that we (should) combine revolutionary sweep with

　　practicalness. "對(duì)我們來說,把革命氣概和實(shí)際精神結(jié)合起來是很重要的。"

　　It is impossible that he should have missed the train. 他不可能誤車。

　　It’s strange that he should have failed in the exam.

　　2. 在ask, require, order, demand, suggest, propose, command, insist?

　　等動(dòng)詞后的賓語(yǔ)從句中, 動(dòng)詞也用虛擬式, 表示命令、建議、要求等。

　　I suggest that we (should) go camping tomorrow.

　　He insisted that our laboratory reports (should) be handed in the day afterthe experiment was done. 他堅(jiān)持要求我們?cè)谧鐾陮?shí)驗(yàn)后第二天將實(shí)驗(yàn)報(bào)告交上來。
