as though =as if
要用虚拟语气,时态要往后面靠一个时态,对现在的虚拟,用过去式
再问：能不能详细点
再答：虚拟语气不是一句两句就能说清的，我给你举几个简单的例子比如说，要是我能飞就好了 i wish i could fly can---could i wish you were a boy are---were(虚拟语气里全用were) 上面是简单的，在条件句里，分别对现在，过去，将来的虚拟，主句和从句的时态，都有固定的模式

he acts as though he did not know anything 为什么时态不一样 He did not know选择 He talks as though he _______(know)all about it.答案是KNEW.为什么? he did not know 后面加任何时态的动词都可以吗? He did not know what _______. Though invited,he did not attend the dinner party. it is not as though he were poor.汉语是什么意思 He did not know what he could do.同意句 He pretended that he did not know the man.
