重点 : 过去动作同时发生的时态
1.过去两个动作同时发生, 习惯上一个用一般过去时, 另一个用过去进行时
; 动作长用过去进行时, 动作短用一般过去时; 分工的情况, 动作的开始时间和
结束时间几乎相同, 均用过去进行时;
　I was listening to the radio, my sister was dancing.
2.两个动作在同时段进行, 在不同时间结束, 先发生的动作未结束, 另一个动作
发生, 先发生的动作用进行时态, 另一个动作用过去时.
When the telephone rang, I was opening the door.先开门
When the telephone was ringing, I opened the door.　电话先响
3.瞬间动词没有进行时态, 所以两个动作同时发生, 延续性动词用进行时态, 瞬间
动词使用过去时态.
