He ( )as if he ( ) me before. A acts, has never seen B acted, had never seen C acts, had never seen解释下，谢谢！

He told as if he knew everything.还是He told as if he had known everything. He looks as if he is ill为什么用if 、 looks as if he was dead 和he looks as if he is dead的区别. If he finds out .Im __ dead A as well as B as far as C as good as D as long he looked as if sick这句话对吗?还是he looked as if is sick? as if 用法有时候是 as if he were.a runner...有时候是 as if he was running...有点糊涂 求翻译.He sounds as if he knows what he's talking about. He opened his mouth as if he were to speak 和He opened his mouth as if he had spoken有什么不同 as if he would ever make such a mistake翻译 he looked as if sick里look是不及物动词? 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 He would,if he could He speaks English as well as,if not betterthan,our english teacher .与He speaks English as well as our English teacher,if not better than him.相同 英语中虚拟语气语法例如He acted as if he were a teacher How he clever is! It seems as if he knows____ A everything B anything 求解释 He looked as if he had lost a pound and found twenty penceTranslate the sentence He spoke as if he were a boss.为什么用were?急.为什么不是was？ foolish as a person is,he can succeed in his work if he works hard.
