1) 概念。

虚拟语气用来表示说话人的主观愿望或假想,所说的是一个条件,不一定是事实,或与事实相反。

2) 在条件句中的应用。

条件句可分为两类,一类为真实条件句,一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。

16.1 真实条件句。

真实条件句用于陈述语气,假设的情况可能发生,其中 if 是如果的意思。

时态关系。句型: 条件从句主句。

一般现在时 shall/will + 动词原形。

if he comes, he will bring his violin.

典型例题。the volleyball match will be put off if it __

a. will rain b. rains c. rained d. is rained

答案b。真实条件句主句为将来时,从句用一般现在时。

注意:1) 在真实条件句中,主句不能用be going to表示将来,该用shall, will.

(错) if you le**e now, you are never going to regret it.

(对) if you le**e now, you will never regret it.

2) 表示真理时,主句谓语动词便不用shall (will) +动词原形,而直接用一般现在时的动词形式。

16.2 非真实条件句。

1)时态:可以表示过去,现在和将来的情况。它的基本特点是时态退后。

a.同现在事实相反的假设。

句型 : 条件从句主句

一般过去时 should( would) +动词原形。

if they were here, they would help you.

b.表示于过去事实相反的假设。

句型: 条件从句主句

过去完成时 should(would) h**e+ 过去分词。

if she had worked harder, she would h**e succeeded.

the rice would not h**e been burnt if you had been more careful.

if my lawyer had been here last saturday, he would h**e prevented me from going.

if he had come yesterday, i should / would h**e told him about it.

含义:he did not come yesterday, so i did not tell him about it.

if he had not been ill and missed many classes, he would h**e made greater progress.

含义: he was ill and missed many lessons, so he did not make greater progress.

c.表示对将来的假想。

句型: 条件从句主句。

一般过去时 should+ 动词原形。

were+ 不定式 would + 动词原形。

should+ 动词原形。

if you succeeded, everything would be all right.

if you should succeed, everything would be all right.

if you were to succeed, everything would be all right.
