英语怎样才能分辨出一般过去时等等之类的?
需要观察句子里面的动词时态,就是主语后面的那个动词的时态.
is am are 是be动词 现在时态/ was were 一般过去式/ have been,have done 现在完成式/ had been,had done 是过去完成式
go,watch,do.实意动词的 现在时态/ went watched did 一般过去式/ have gone have watched have done 现在完成式/ had gone had watched had done 过去完成式
can may 情态动词 现在式/ could might 过去式
或者是通过具体的时间状语来判断,例如,yeaturday,last year,1950,
