希望给出充分的理由说明see sb doing sth与see sb do sth的区别
1.——Do you often see William ___ on the playground?
——No,but he is often seen ___ Chinese Kungfu in the park.
A.run;play
B.run;to play
C.running;play
D.running;to play
2.I heard him ___ in the room almost every day.
A.sing
B.singing
C.sings
1.B
see sb.doing sth.是表示看见某人正在做某事
see sb.do sth.是表示看见某人做了某事,是看了整个过程,也可以近似看做是一种状态.
而第二个空选to play是因为那里是被动语态,原本省略的to要还原.
2.A,因为我是从头听到尾的.
