为什么(1)we don‘t have any problems后用finding 而He left home in hurry because he had some problems后用to solve (2)为什么how can you make yourself 后用understand的过去式
He left home in hurry because he had some problems后用to solve 他匆忙离开家因为他有有问题要解决.不定式表示将来. how can you make yourself 后用understood make oneself understood 使自己被(别人)理解 过去分词表示被动
(1)have problem to do sth.是有问题要解决的意思,而finding,是省略了介词(in) (2)make sth done这一机构中,sth.是make的宾语,而宾语补足语done和宾语sth.之间是被动关系,所以用过去分词,表示被动。make sb done这一结构中的sb只能是反身代词oneself或其复数。
