looked 是过去式或过去分词,look是动词原形,也就是现在式 looked和look都可以做谓语动词,只是时态不同 looked做过去分词还可以与介词等连用做定语或状语;而look无此用法
1.你的翻译是对的.这句话就是这么简单. 2.都可以互换的,都是“看起来”的意思.也可以用seems to be来替换looked as if来造句. 3.这句话是虚拟语气,,这里的if不是虚拟语气的标志,were才是. looked前面不加was, looked表示的是过去式,而且look as if是固定搭配.
had looked. had look doesn't make sense. had to look is the correct way of saying it.
这有关虚拟语气与现在相反,则用过去式,be动词虚拟语气用were与过去相反,用过去完成时She looks as if she were five years younger.从looks表示与现在相反,所以用were是对的She looked as if she were five years younger.从looked看出与过去相反,则后面应该用had been
必须是looked at 因为look不可以带宾语
是down吧,像please,look down,请往下看,还有look down on sb,看不起某人/鄙视某人
