___after a long walk,Tom called and said he could not come to the party.A.Worn out B.Having worn out横线上是选择A,我想问为什么出现after就不能用having?

___after a long walk,Tom called and said he could not come to the party.A.Worn out B.Having worn...___after a long walk,Tom called and said he could not come to the party.A.Worn out B.Having worn out横线上是选择A,我想问为什么出现after
因为只有在a long walk 之后才wear out(精疲力竭),如果用了having 则显示出没有客观条件就已然疲惫不堪,这与事实不符,或者说与after齐用时会略显累赘,英语讲究达练而不是冗余.

本句话的意思是“走了好一段路之后疲惫不堪”,worn out是走路后的结果,而不是在走路之前,不可用完成时。

after虽然是介词,但一般doing加在后面,而不会加在前面。

called and said 这个已经是过去时了,说明就不能用现在完成时了,所以就选择A 了。
