done,tobe done,to have been done,to have done,having done,ha
2个回答

to do to be done 表示目的和将来 非谓语的动作几乎和谓语动作同时发生或将要发生

to have done to have been done 表示非谓语的动作发生在谓语动作之前

having done having been done表示进行和主动 而且非谓语的动作发生在谓语动作之前

done 表示被动和完成

There is a lot of work to do 或者to be done 都可以

With a lot of work to do,he went out to play.这一句是错的 ,应改为With a lot of work done,he went out to play

明白吗?
