83、You need to come earlier,you?A.don’t you B.needn’t C.don’t D.won’t
选B为什么错了?

A 这里need作实义动词
1.need to 作情态动词,通常用于疑问句、否定句、条件句、 whether(if) 名词从句或含否定意义的句子中.如:
I do not see why we need discuss it further.
我看我们没有必要讨论下去了.
That's all settled.It needn't be talked about.
那已全部解决了,没有必要再说了.
He asked me whether he need attend the meeting?
他问我他是否有必要出席这次会议?
2.need 又是实义动词,各种变化和用法与普通实义动词相同.如:
They need a rest after a long walk.
长距离行走后他们需要休息一下.
I need you to work for me,young man!
小伙子,我需要你为工作.
3.need 接动名词主动形式,表示被动意义、这时动名词和主语之间有动宾关系,need doing 可转换为 need to be done 结构,意思相同.如:
My hair needs washing badly.(= My hair needs to be washed badly.)
我的头发非常需要洗一洗.
The garden needs watering.(=The garden needs to be watered.)
花园需要浇水.
