He acted as if he ___everything in the world.A.knew B.knows C.has known D.won't know这个题不是对过去的虚拟吗?怎么选啊,

英语中虚拟语气语法例如He acted as if he were a teacher .He acted as if he had never lived in England before 划分句子成分 he always acted as if he thought I wasn't one of the family怎么翻译? 这个人装穷,he acted as if he __poor 填什么 老师说是was 但不是说虚拟语气没有was吗 只能填were 填什么he acted as if he was poor 理由 老师说的he acted as if he were poor 理由 虚拟语气he acted as is he had been poo acted as if he had never been abroad before.句子成分怎样划分? acted ( )he had never lived in England beforehe acted ( )he had never lived in England beforea)as though b)likec)asd)even if He acted as if he had never lived in England before.这句话中为什么最后加了个before 在“He acted as if he were smoking.”中,为什么不用was而用were?请说明理由, he acted as if he had never lived in england before acted是什么词?翻译是他的举动好象他从未在英国生活过一样 那acted是名词吗 不太理解 I acted as if he had never lived in England before这是宾语从句还是状语从句 关于连词成句的一道题Tom as if he acted had been never before here 一道英语辨析题,He acted( )he had never lived in England before.A.as though B.like C.as D.even if he acted as if he had never lived in England before后面用了虚拟语气,额 说明一下这其中的 虚拟语气的结构啊. He acted as if he had never lived in England before.这句话是状语从句,请帮我改成定语从句和宾语从句. 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！ 虚拟语气 he acted as if he( )everything in the world A.knew B.knows C.has known D.won't know为啥?俺知道是虚拟. He acted as if he had never seen a plane before in his life.请问这句话中‘‘had never seen’’ 虚拟语气 he acted as if he( )everything in the world A.knew B.knows C.has known D.won't know这不是表示与过去相反吗?因为是acted 是过去式啊
