no否定名词时,什么时候名词用单数,什么时候用复数.
1.The flowers [B ]
A.are needed to water B.need watering
此题,物做主语时是否只能用+doing的句型?
如果不是,那么什么时候用被动语态呢?
2.Who did you find in the room?
[ A ]
A.nobody B.none
此题为什么不选none
答
need doing=need to be done
The flowers need watering 就是说,这花需要给它浇水了(花需要被浇水)
这是need的一个特殊用法
the clothes needs washing.
the child needs feeding.
the homework needs writing.
2.Who did you find in the room?你在房间里发现谁了?
nobody是指“没人”,一般用who提问时,说没人用nobody,特指的是人;
而如果问what did you find in the room(你在房间里发现什么了?)要用none,什么都没有.
nobody没有人;none什么都没有.
