They had a compition to see who could throw the furthest.

题目

They had a compition to see who could throw the furthest.
他们举行了一场比赛,看谁投得更远
本句的动词不定式是否作后置定语,若是的话,为什么不用"seeing"动词-ing形式做后置定语?
那么I threw open the windows to let the smoke out.
我猛的推开窗户，让烟散出去．
也是属于to+动词表目的的吗？

答案

表目的当然要用to+动词,表伴随状态用ing,而且see 是个很短的动作,不能用seeing.用了也要用watching
