请参考非谓语动词考点。例如:
1. finish, enjoy, imagine, consider, suggest, escape, miss,avoid后一般要跟v-ing分词。
2. have sth done,get sth done,leave sth undone等
3. make oneself understood / heard / known /seen
但是,have sb do sth, have sb doing sth, have sth done等,具体要看用法和情景。
再如:be left doing, be left undone/ be made known, be caught doing sth
语法有很多规律,但是没有捷径,必须一点一点来。以上仅仅是非谓语动词的很小一部分。
