Jim hurt his arm while/when/as he was playing tennis. As/When/While she was waiting for the train, she became very impatient. 注意：as用于引出一个持续性动词表示“在……期间”时，其 谓语通常只能是那些含有动作和发展意味的动词，一般不能是 那些不用于进行时态的动词(如be, seem, love, want, agree, see, know, have等)，所以下面一句 中的while不能换为as： A：I'm going to the post office. B：While you are there, can you get me some stamps?
