语法 Grammar in use
一般过去时(cf.第3课语法)
在并列句中，各分句在时态上通常要保持一致。在叙述过去发生的事件时，动词基本上都用一般过去时，但有时也会出现过去完成时和过去进行时，它们的同时使用并不违反动词的"一致原则"：
They all leapt out of their sleeping bags and hurried outside. It was
raining heavily and they found that a stream had formed in the field.
他们全都跳出睡袋，跑到外面。雨下得很大，他们发现地上已经形成了一条小溪。
由于一般过去时常常表示过去某个特定的时间发生的事件，因此，它常与when，where等疑问词连用。除了时间状语可以表示特定的时间之外，地点状语也可以暗示或包括特定的时间：
Where did you last see her?你最近在什么地方见过她?
一般过去时与一般现在时在上下文中同时使用可以表示对比：
