请问He talks as though we were all stupid and he alone clever.

He talks as though he ___（know）all about it.请问这个应该填什么? He talks as though he knew everything He talks as though he _______(know)all about it.答案是KNEW.为什么? 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 I can’t stand him.He always talks as though he ___ everythin He talks as if he were the head of the office.为什么此处是用were而不是 英语语法He has just arrived,but he talks as if he ___A__ all abo 帮我解道题He has just arrived, but he talks as if he ___ all abou 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 he is such a clever boy that we all like him=he is so clever He talks as if he had done all the work himself.怎么翻译?
