在lest that, for fear that, in case that等引導(dǎo)的表示消極意義的目的狀語(yǔ)從句中,常常用到虛擬語(yǔ)氣,結(jié)構(gòu)用should+動(dòng)詞原形,且should能省略。例如:I keep some candle in the house in case that electric power should fail.

由would rather/sooner, would sooner, had rather, would just as soon, would prefer等結(jié)構(gòu)引導(dǎo)的虛擬語(yǔ)氣,其句型結(jié)構(gòu)是這樣的:如果與過(guò)去事實(shí)相反,用"would rather/sooner...謂語(yǔ)動(dòng)詞用had done";如果與現(xiàn)在、將來(lái)事實(shí)相反,用"would rather/sooner...謂語(yǔ)動(dòng)詞用did"。

如果使用虛擬語(yǔ)氣,在so that, in order that所引導(dǎo)的目的狀語(yǔ)從句中,從句中的謂語(yǔ)為:can/could/may/might/will/would/should+do.比如:He goes closer to the speaker so that he can hear him clearer./He read the letter carefully in order that he should not miss a word.

當(dāng)insist意為"堅(jiān)持某種動(dòng)作"時(shí),才需要用虛擬語(yǔ)氣。如果它的意思是"堅(jiān)持某種觀點(diǎn),某個(gè)事實(shí)",就不需要用虛擬語(yǔ)氣了。比如:He insists he is a student.這個(gè)語(yǔ)句表示的是事實(shí),因此在這個(gè)語(yǔ)句中不能使用虛擬語(yǔ)氣。
