（wore ）out after the mountains,they ha

题目

（wore ）out after the mountains,they ha
（wore ）out after the mountains,they had to take a good rest 为什么括号里是wore不是wearing
my leg wore out 不是没有被动么

答案

wear-wore-worn
wear out磨损,动词短语.这里应该用过去式,由于wear的过去式是wore,所以应该填wore out.
被动语态应该是过去分词,所以这里只是过去式而不是被动语态.
祝天天向上
