救命how much time do you need?

题目

救命how much time do you need?
(need后边是否一定要跟什麼呢?可以就这样问么?)
how much time do you need?
how much time do you need to finish?(这可以么?)
还是要 take to finish?
还是我多此一问...

答案

二楼说的没错,此处need是一个及物动词.但need也可以是不及物动词,或是系词.此处的语句是:
how much time do you need (it)?
它的用法如同:
how much do you pay (it)?你要付多少钱?
疑问句的宾语提前了.所以就不必再用it了!
至于第二句,how much time do you need to finish?此处的need是一个系词,而非再是有意思的动词了.所以应该把need to 看作一体.但这个用法是有错的,因为finish是一个及物动词,而complete则是不及物动词,所以,如果你使用:
how much time do you need to complete是正确的,而这一个要用
how much time do you need to finish it/job/work才是正确的!除非finish也可以作为不及物动词使用.
这两个need在这两句中的意义是不同的.第一句中的do是修饰的need,而第二句中的do修饰的是need to后的动词.还有一个用法就是:
how much time need you to finish it?
这句你可以清楚地看到need是一个系词用的,而非动词用!
