真实条件句和虚拟条件句

真实条件句和虚拟条件句（Units 9, 10）（重难点）

真实条件句表示现在或将来可能发生的事情或存在的情况，虚拟条件句表示纯属假设的不可能发生的事情或存在的情况，它是与事实相反的愿望、假想。本学期要求掌握与现在事实相反的虚拟条件句。

真实条件句的构成：“If + 从句主语+ 一般现在时，主句主语+ will/won’t + 动词原形”

If we bid for the games, we will promote the country.

虚拟条件句的构成：“If + 从句主语+ 动词过去式，主句主语+ would (’d ) + 动词原形” If I had the time, I’d make something better. 注意：在这种与现在事实相反的虚拟条件句的if 从句中，不论从句主语是什么人称，be动词都常用were。If my grandmother were alive, I’d ask her. If I were you, I’d ask her.
