虛擬語(yǔ)氣
1.概念
虛擬語(yǔ)氣用來(lái)表示說(shuō)話人的主觀愿望或假想，所說(shuō)的是一個(gè)條件，不一定是事實(shí)，或與事實(shí)相反。
2.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。非真實(shí)條件句表示的是假設(shè)的或?qū)嶋H可能性不大的情況，故采用虛擬語(yǔ)氣。
真實(shí)條件句
真實(shí)條件句用于陳述語(yǔ)氣，假設(shè)的情況可能發(fā)生，其中if是“如果”的`意思。
時(shí)態(tài)關(guān)系
句型：條件從句+主句 一般現(xiàn)在時(shí)：shall/will + 動(dòng)詞原形
If he comes, he will bring his violin.
典型例題
The volleyball match will be put off if it ___.
A. will rain B. rains C. rained D. is rained
答案B。真實(shí)條件句主句為將來(lái)時(shí)，從句用一般現(xiàn)在時(shí)。
注意：
1) 在真實(shí)條件句中，主句不能用be going to表示將來(lái)，該用shall, will.
(錯(cuò)) If you leave now, you are never going to regret it.
(對(duì)) If you leave now, you will never regret it.
2) 表示真理時(shí)，主句謂語(yǔ)動(dòng)詞便不用shall (will) +動(dòng)詞原形，而直接用一般現(xiàn)在時(shí)的動(dòng)詞形式。
