A 這里need作實(shí)義動(dòng)詞
1.need to 作情態(tài)動(dòng)詞,通常用于疑問(wèn)句、否定句、條件句、 whether(if) 名詞從句或含否定意義的句子中.如：

我看我們沒(méi)有必要討論下去了.

那已全部解決了,沒(méi)有必要再說(shuō)了.

2.need 又是實(shí)義動(dòng)詞,各種變化和用法與普通實(shí)義動(dòng)詞相同.如：
They need a rest after a long walk.
長(zhǎng)距離行走后他們需要休息一下.
I need you to work for me,young man!
小伙子,我需要你為工作.
3.need 接動(dòng)名詞主動(dòng)形式,表示被動(dòng)意義、這時(shí)動(dòng)名詞和主語(yǔ)之間有動(dòng)賓關(guān)系,need doing 可轉(zhuǎn)換為 need to be done 結(jié)構(gòu),意思相同.如：
My hair needs washing badly.(= My hair needs to be washed badly.)
我的頭發(fā)非常需要洗一洗.
