我是這么總結(jié)的,
如果翻譯成必需做某事,就是情態(tài)動(dòng)詞
如果翻譯成需要做某事,就是實(shí)意動(dòng)詞
情態(tài)動(dòng)詞need只用于疑問(wèn)句和否定句,用來(lái)表示有必要嗎或沒(méi)必要.肯定式是must.
不能接名詞,只能和普通動(dòng)詞不定式構(gòu)成合成謂語(yǔ),無(wú)人稱和時(shí)間變化.
Need you go there now
Yes,I must .No,I needn’t.
實(shí)意動(dòng)詞need不能提前疑問(wèn)也不能加not否定,含義是需要.疑問(wèn)和否定要借助于特殊動(dòng)詞do.可以接名詞做賓語(yǔ).也可以跟to do(=have to do) ,doing 做賓語(yǔ).有時(shí)間和人稱變化.跟-ing做賓語(yǔ)時(shí),其主語(yǔ)往往是物,主動(dòng)形式表被動(dòng)結(jié)構(gòu).
I need to use the bathroom.

Yes,I need a book.No,I don’t need a book.
