He walks slowly as though he were sick.这句话中从句里用了were,请问这里涉及到 He appeared as if he were sick.后面虚拟语气为什么用were而不是had been He looks as if he were angry.请问这句话中as if引导的表从还是状从? he speaks as if he were an Englishman 这里的 were可以用 He speaks English as though he were an American.为什么是he were而 it is not as though he were poor.汉语是什么意思 she walks as if she were drank 这里可以用were drank That proud woman acts as though she were above us这里为什么用were不 He is f-- in English as though he were a native speaker He was ill ,as were other passengers.这句话中为什么不能直接说as other pa He speaks English as if he were an Englishman.这里的he不是单数吗为什么用 "He looks as if he were hungry"是表语从句还是方式状语从句?如何判断?
