一，一般过去时常用的时间是：last+时间, 一 段时间+ago,
yesterday, the day before yesterday
例如：He visited his parents yesterday.
二，现在完成时的“未完成”用法。
本用法表示动作或状态从过去某时开始，延续至今，可能结束，也可能继续下去。常与for短语，since 短语或since从句连用，可以用how long提问。谓语动词用延续性动词。
1,一般过去时的句子改为现在完成时的句子。

join → marry →

come to → get up →

方向一　根据时间状语标志词确定时态
动词的时态常与特定的时间状语紧密联系，例如，由so far, in the past two years, till now可判断句子的时态用现在完成时；由yesterday, just now可判断句子的时态用一般过去时等。
方向二　根据固定句型与时态之间的关系确定时态
在英语中，不少句型与一些动词在时态的运用方面都存在着特定的对应关系，如：
(1)在“祈使句＋and/or＋陈述句”句型中，陈述句与will连用表示一般将来时；
(2)was/were doing...when...，when分句的谓语动词用一般过去时；
(3)在一个含有时间状语从句的主从复合句中，如果主从句的谓语动词都是过去发生的动作，一般来说，表示短暂性动作的动词用一般过去时，表示持续性动作的动词用过去进行时。
方向三　根据句意和语境确定时态
大多数时候，动词的时态是由前后句、上下文语境来决定的。要求考生一方面熟记各种时态的用法，另一方面要注意前后语境间的潜在提示。
倒装句用法
