虚拟语气可以用在进行时和完成时吗

as if的虚拟语气表对现在的虚拟用were或did，是否可以既表示虚拟又表示进行或完成？

例：It seems as if he is leaving.他好像要走。这句话变虚拟语气可以直接把is变成were吗？

例：It seems as if he is doing his homework.他好像在做作业。这句话变虚拟语气可以直接把is变成were吗？

例：It seems as if the thing reported on the news has been proved.新闻上报道的事好像已经被证实了。这句话变虚拟语气可以直接把has变had吗？

以上三个问题的答案都是：Yes。

It seems as if he were leaving.

It seems as if he were doing his homework.

It seems as if the thing reported on the news had been proved.

但这是较早期的as if从句动词形式。现代英语中，如果as if从句表示的内容如果有可能是事实，则多用陈述语气。即你的原句。
