Question

as if 引导的虚拟语气是什么？

Answer 1

as if 从句用虚拟语气，当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下：

1、如果从句表示与现在事实相反，谓语动词用一般过去时。

2、从句表示与过去事实相反，谓语动词用“had＋过去分词”。

3、从句表示与将来事实相反，谓语动词用“would／could／might＋动词原形”。例如：

You look as if you didn’t care．你看上去好像并不在乎。

He talks about Rome as if he had been there before．他说起罗马来好像他以前去过罗马似的。

He opened his mouth as if he would say something．他张开嘴好像要说什么。

as if 从句的作用：

1、在look，seem等系动词后引导表语从句。

She looks as if she were ten years younger.

她看起来好像年轻了十岁。

2、引导方式状语从句

She loves the boy as if he were he father.

她爱这个男孩，就好像他是她的父亲一样。
