幻灯片 4动词的时态(2)
一、一般过去时通常表示过去一段时间的习惯性动作或状态或过去某一具体时间发生的动作或所处的状态。但过去时有时并不实际表示过去的动作或状态。受主句过去时态影响，从句用过去时态；表示虚拟语气时用过去时态。与一般过去时连用的时间状语(举例时)有 yesterday, (two days…) ago, last (year…)，the other day(前几天)，once upon a time(很久以前)，just now(刚才)，in the old days(在过去的日子里)，before liberation(解放前……)，When I was 8 years old(当我8岁时……)，at (7 o'clock…)等。

幻灯片 6二、过去进行时的动词主要表示在过去某一时刻或某一段时间内正在进行或持续进行的动作。过去进行时动词与always, continually, frequently 等词连用时，表示明显的感情色彩。进行时与when连用表达“正在做某事，突然……”的意思。短暂性动作用于进行时时，表达“慢慢地”的意思。常见时间状语有this time yesterday/last month/last year等，表达“过去这个时候”的意思。
----
幻灯片 7三、过去完成时的基本含义表示在过去某一参照时间或动作之前动作已经发生或到过去某一参照时间或动作为止动作或状态已经持续一段时间。用过去完成时，必须有一个过去的时间或动作来作参照，说明在此之前某动作已发生或某状态已经存在。体会 “过去的过去”或“从过去到过去”是理解过去完成时的关键。具体时间状语有：by＋过去时间或before＋过去时间。
