032第三条件从句

032第三条件从句

第三条件从句本课中我们将学习有关第三条件句。

我们将学习如何使用及如何和其他两种条件句的区别。

第一和第二条件从句注重可能的将来条件。

使用第三条件从句谈论过去情况。

我们用作非正事实的过去情况或想象中的情况,换句话说某情况和结果并没有发生。

看以下的句子:If John had driven more carefully, he wouldn't have had this accident. John小心开车了吗?没有John遇到了交通意外了吗?是的象第一和第二条件从句,第三条件从句包括两个部分:▪'if'从句(条件)▪一个结果从句(结果或作用)使用第三从句,然而,结果已经不可能发生,并且不可能改变结果。

我们谈论过去的情况及过去的结果。

例如If I hadn't gone out last night (不真实的过去情况), I wouldn't have been tired this morning (不可能的过去结果。

象第一和第二条件从句,第三条件从句包括两个部分:▪'if'从句(条件)▪一个结果从句(结果或作用)使用第三从句,然而,结果已经不可能发生,并且不可能改变结果。

我们谈论过去的情况及过去的结果。

例如If I hadn't gone out last night (不真实的过去情况), I wouldn't have been tired this morning (不可能的过去结果。

第三条件从句是不真实的,因为它现在太迟了结果已经不可能发生了。

第三条件从句常常用来回顾并表达某种遗憾:我应该这么做的但是不幸的是我没有这么做。

在大多数的第三条件从句中,结果是非常明显的。

我们可以省去结果从句只是表达我们的遗憾,以'If only'或 'I wish'开始。

例如If only I'd studied for the exam…(如果事先准备考试的话我就不会不及格了。
