應(yīng)該叫助動(dòng)詞.
英語(yǔ)中的助動(dòng)詞有以下這些：
1、 be been being am are is was were ;
2,have has had having ;
3,shall will shoud would ;
4,do does did ;
這些助動(dòng)詞一般沒(méi)有意義,主要幫助構(gòu)成謂語(yǔ),表示時(shí)態(tài)、語(yǔ)態(tài)、語(yǔ)氣等.或構(gòu)成疑問(wèn)及否定形式.
但有些助動(dòng)詞如shall ,will ,shoud ,would ,有時(shí)有一定的詞義,作用接近情態(tài)動(dòng)詞,這時(shí)很難說(shuō)它是情態(tài)動(dòng)詞還是助動(dòng)詞.
