_________________________________________________________________________________________________狀語從句中的虛擬語氣
虛擬語氣在if引導(dǎo)的條件句中的用法三點(diǎn):
從句(條件)
主句(目的)
表示于現(xiàn)在事實(shí)相反的虛擬條件句
If+主語+動(dòng)詞的過去式(be用were)
主語+wuld(shuld culd might)+動(dòng)詞原型
If I were yu, I wuld seize the chance t g abrad.
表示與過去事實(shí)相反的虛擬條件句
If+主語+had+動(dòng)詞的過去分詞

表示與將來事實(shí)相反的虛擬條件句
If+主語+shuld(were t)+動(dòng)詞原型/動(dòng)詞的過去式
主語+wuld(culd shuld might)+動(dòng)詞原型
If he did nt cme tmrrw, we wuld put ff the meeting till next Mnday.
混合條件句——主從句時(shí)間不一致的情況下的虛擬語氣
有時(shí)條件從句中的動(dòng)作與主句中的動(dòng)作,發(fā)生的時(shí)間不一致,這是動(dòng)作的形式應(yīng)根據(jù)它所表示的時(shí)間加以調(diào)整。
If yu had studied hard befre, yu wuld be a cllege student nw.
含蓄條件句
有時(shí)虛擬條件句并沒用if從句表示出來,而是用介詞短語(therwise,r,withut,but fr)上下文或其他方式來表示。
1. Withut yur help, we culdn’t have finished the wrk ahead f time.
= But fr yur help,…= If it had nt been fr yur help,…
2. I was ill that day. Otherwise, I wuld have taken part in the sprts meeting.
條件從句中省略if采用倒裝語序的情況
在if引導(dǎo)的表示虛擬的條件狀語從句中,有時(shí)可以把虛擬條件中的連詞if省去,而將had,shuld,were等助動(dòng)詞提到主語之前。
例: If she were yunger, she wuld d it.
Were she yunger, she wuld d it.
If yu had cme earlier, yu wuld have caught the bus.
Had yu cme earlier, yu wuld have caught the bus.
虛擬語氣在as if/as thugh引導(dǎo)的方式狀語從句中
1.表示與現(xiàn)在事實(shí)相反或?qū)ΜF(xiàn)在情況有懷疑,謂語動(dòng)詞用過去式。

2.表示與過去事實(shí)相反,謂語動(dòng)詞用過去完成時(shí)。
She speaks English s fluently as if she had studied English in America.
3. 表示與將來事實(shí)相反,從句用wuld/culd/might+動(dòng)詞原形
He learns English s hard as if he wuld g t the
注意:1.在as if/as thugh 句中,如果有可能成為事實(shí),用陳述語氣。例:He lks as if he ging t be ill.
2.as thugh或as if引導(dǎo)的狀語從句,從句主語和主句主語相同時(shí),從句中可省略主語和部分謂語。
名詞性從句中的虛擬語氣
賓語從句中的虛擬語氣

注意:suggest, insist不表示建議或堅(jiān)持要某人做某事時(shí),即它們用于其本意暗示,表明,堅(jiān)持認(rèn)為時(shí),賓語從句用陳述語氣。
3.wuld rather,had rather,后的賓語從句中的虛擬語氣
謂語動(dòng)詞用過去式表示與現(xiàn)在或?qū)硐喾?,用過去完成式表示與過去事實(shí)相反。表示“寧愿做什么”或“對(duì)過去做的事的懊悔”。
