語(yǔ)可以表示 含蓄的條件 。 例句: ? With your help, we could have done better. ? Without air, there would be no living things. ? But for your help, I wouldn’t have passed the exam. (7)虛實(shí)錯(cuò)綜句: 有時(shí)虛擬現(xiàn)象與客觀事實(shí)錯(cuò)綜交織在一起,需要我們判斷哪一處是虛擬語(yǔ)氣,哪一處是陳述語(yǔ)氣。 ? I was busy that day. Otherwise I would have gone there with you.( 第一句說明當(dāng)時(shí)的事實(shí),是陳述句; otherwise后面是隱含條件的虛擬語(yǔ)氣。) ? I could have finished the work, but I was ill then.( 前句是隱含條件的虛擬語(yǔ)氣,后句 but表示轉(zhuǎn)折,說明當(dāng)時(shí)的事實(shí),是陳述句。) 2. 動(dòng)詞 wish后的賓語(yǔ)從句表示不可能實(shí)現(xiàn)的愿望,因此從句中要用虛擬語(yǔ)氣。從句中謂語(yǔ)動(dòng)詞的形式為: S + wish + (that) +: S + 動(dòng)詞過去式( be多用 were)( 表現(xiàn)在) S + had + 過去分詞(表過去) S + could/would/might + 動(dòng)詞原形(表將來) 例句: ? I wish I knew the answer to the question. ? I wish it were spring in Beijing all the year round. ? I wish(ed) I hadn’t spent so much money. ? I wish I would go abroad some day. 3. 虛擬語(yǔ)氣用于 as i
