Question

英语语法问题请教。。。谢谢了？

He opened his mouth as if he would say something.
他张开嘴好像要说什么。
请问大家这句话里的as if 可以更换成 as though 吗？

Answer 1

回答如下：
是的，本句中的as if可以换成as though，它们的意思和功能一样，都是作方式状语从句。
as if / as though (好像，仿佛)可以引导表语从句、方式状语从句，它们既可以用陈述语气，也可以用虚拟语气，这要看它们所陈述的情况是真实情况，还是非真实情况。例如：
He looks as if / as though he were very old.
It seems as if / as though he knows it.
He talks as if / as though had been to Paris.
He eats as if / as though he has not eaten for two days.

追问

非常感谢您！

Answer 2

He opened his mouth as if he would say something.
这个句子中的as if 可以用as though 来代替。 两者都是虚拟语气从句的关联复合代词， 意思是似乎/好像…：
He opened his mouth as though he would say something.
他张开嘴，好像要说什么似的。

Answer 3

可以的，这里as if 是似乎，好像的意思，可以换成 as though

Answer 4

应该是不可以的，因为as if在这里表虚拟语气，你看后面半句有would，在其它条件下是可以替换的，希望采纳！

Answer 5

as if 可以与as though 可以互换，都是虚拟语气引导词。
