这是一个很好的问题! a s是可以像使用的结合when或while 。这就是这里的用法。您可以使用a s在感during the time that来连接两个事件或情况在同一发生during the time that 。 A s ,您可以使用动词的简单现在或连续形式。在这句话中,使用了简单的现在时race 。示例: Another coach-load of people arrived as we were leaving. (其他大型巴士上的人在我们出发时到达。)例子: We were lying on the beach sunbathing as they were playing volleyball. (我们躺在沙滩上晒日光浴,他们在打排球。)
