问题 These windows need ______. Can you do them?
选项 A、clean
B、cleaned
C、to clean
D、cleaning
答案 D
解析 need后面接动名词时，主动表被动。need doing与need to be done的含义是一样的。本题的正确答案选D。[拓展]want，need后面接动名词形式表示被动的含义，构成 sth. need/want doing (=sth. need/want to be done)的结构。例：Those flowers need watering/to be watered．那些花需要浇水了。The house needs cleaning/to be cleaned．房间需要打扫了。
