二)动词-ing在句中作表语：

Our plan is setting up a new car factory.

这类词作表语，起解释说明主语的作用，主表可颠倒：Teaching is my job. 转换

三)need, require, want译作“需要”时，跟动词-ing作宾语，主动表示被动，相当于to be done，如：

2.The patient needs operating on at once. (The patient needs to be operated on. )

3.The flowers want watering. (The flowers want to be watered. )
