6、語(yǔ)從句，謂語(yǔ)動(dòng)詞常用虛擬語(yǔ)氣，"should動(dòng)詞原形"構(gòu)成，should 可省略。 4、 有時(shí)，主句和條件狀語(yǔ)從句的謂語(yǔ)動(dòng)作假設(shè)不是同時(shí)發(fā)生時(shí)，虛擬語(yǔ)氣的形式應(yīng)作相應(yīng)的調(diào)整。 從句的動(dòng)作與過(guò)去事實(shí)相反，而主句的動(dòng)作與現(xiàn)在或現(xiàn)在正在發(fā)生的事實(shí)不符。如： If I had worked hard at school, I would be an engineer, too. 如果我在學(xué)校學(xué)習(xí)刻苦的話，我現(xiàn)在也會(huì)成為一個(gè)工程師了 If they had informed us, we would not e here now. 如果他們通知過(guò)我們的話，我們現(xiàn)在就不會(huì)來(lái)這里了，從句

8、好。 If he had been working hard, he would be working in the office now. 要是他一直努力工作的話，他現(xiàn)在已進(jìn)了辦公室了。 5、 當(dāng)虛擬條件句的謂語(yǔ)動(dòng)詞含有were, should, had時(shí)，if可以省略，這時(shí)條件從句要用倒裝語(yǔ)序，即將were, should, had等詞置于句首，這種多用于書(shū)面語(yǔ)。如： Should he agree to go there, we would send him there. 要是他容許去的話，我們就派他去。 Were she here, she would agree with us. 如

11、t home now. 要是我現(xiàn)在在家里該多好啊。 If only I had got it. 要是我得到它了該多好啊。、虛擬語(yǔ)氣Subjunctive Mood)的其他用法1、虛擬語(yǔ)氣用在wish 后的賓語(yǔ)從句a、表示與現(xiàn)在事實(shí)相反的愿望，謂語(yǔ)動(dòng)詞用過(guò)去式 eg.
