want 表示需要时, 后接动名词的主动形式表示被动意义,所以答案要选 C, 相当于 wants to be cut。
Your hair wants cutting.= Your hair wants to be cut. 你的头发要理了。
Our house wants painting.= Our house wants to be painted. 我们的房子需要粉刷了。
This bill wants paying.= This bill wants to be paid. 这个账单需要支付。
The supper dishes want washing.= The supper dishes want to be washed. 晚餐用过的餐具得洗了。
这样用的 want
也可换成 need。
