一句有as if的句子She looks as if she were ten years younger．请问在这句话中looks as是一般现在是,可为什么后面were ten years要用到过去时 it looks as if she 's 关于as if引导表语从句和宾语从句.语法书中说下面这句话中as if引导的是表语从句：It looks as if it is going to rain.那么为什么有的语法书中说下面的句子中as if 引导的是壮语从句：She looks as if sh as if的用法1.She loves the boy as if she were his mother2.She looks as if she were five years old3It seems as if our team is going to win为什么1和2的时态不一致 looks as if he was dead 和he looks as if he is dead的区别. 请问啊 Now she looks pale as if she were ill谢! 为什么时态不一致1.She loves the boy as if she were his mother2.She looks as if she were five years old She looks as if she were ten years younger．为什么she之后用 were 而不是was? 请英语老师或英语专业成绩好的同学帮我解释一下：It looks as if she had just come back fromouter space.为什么用的是过去完成时,looks不是现在时吗?为什么不用过去时came back? 谁能帮我分析下这个英语句子的结构?It looks as if spilled some silver powder.这个是主系表结构还是主谓宾呢? It looks as if children were a lot better off in 2001 than they were in 2002上面句子里的“off”怎么理解？ she looks的一条 as和as if作为好像的意思时有什么区别?比如说这两个句子：He looked just as he had looked ten years before.She looked as if she were ten years younger. 帮我看看as if后面be动词的用法区别He looks as if he were ill.He looks as if he is ill.都是他仿佛病了.还有He looks as if he were sleeping.和He looks as if he is sleeping.都是一个意思,用were的一定是虚拟语气了,但 请从虚拟语气角度解释下列问题的答案If only I___a very beautiful lady.A have been B hadShe looks as if she ____for several months.A hadn't eaten B haven't eaten 请英语老师或英语专业的同学帮我解释一下,帮我解释以下这个关于as if 的语法It looks as if she had just come back from outer space.（她看起来仿佛从外太空回来似的）looks 是现在时,照时态后推的道理 He looks as if he is ill为什么用if 、 It looks as if it is going to rain. 句子中哪个是主语,哪个是表语,哪个是?
