【正文】 不大的情況，故采用虛擬語氣。 二、 在條件句中的應(yīng)用： 條件句可分為兩類，一類為真實(shí)條件句，一類為非真實(shí)條件句。 真實(shí)條件句主句為將來時，從句用一般現(xiàn)在時。a. 同現(xiàn)在事實(shí)相反的假設(shè)。） If it had rained last night (過去 ), it would be very cold today (現(xiàn)在 ). 虛擬條件句的倒裝：虛擬條件句的從句部分如果含有 were, should, 或 had, 可將 if省略，再把 were, should或 had 移到從句句首，實(shí)行倒裝。 典型例題：_____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案 C. 在虛擬條件狀語中如果有 were, should, had這三個詞，通常將 if省略，主語提前 , 變成 were, should, had +主語的形式。（ 1） It is demanded / necessary / a pity + that… 結(jié)構(gòu)中的主語從句的謂語動詞要用 should 加動詞原形， should 可省略。在 suggestion, proposal, idea, plan, order, advice等名詞后面的表語從句、同位語從句中要用虛擬語氣，即（ should） +動詞原形。He wished he hadn39。Wish sb. / sth. to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.)比較 if only與 only if。 If only the alarm clock had rung. 當(dāng)時鬧鐘響了，就好了。It is time that the children went to bed.
