自主探究
1. I stopped using them last year. 去年我就停止使用他们了。
【解读1】此句子的时态为一般过去时态,常与其连用的时间状语有:yesterday/ last week/ last month/ last year/ …ago…
【举例】He waited for you here three hours ago.三个小时以前他在这里等你。
【解读2】stopped为stop的过去式。在英语当中动词的过去式分为规则变化和不规则的变化,不规则动词总数大概不过200多个,但是使用频率很高。主要分成三类:
1、第一类不规则动词的三种形式同形,如:cost cost cost/ cut cut cut/ hurt hurt hurt
2、第二类不规则动词的过去式和过去分词同形,如:bring brought brought/ catch caught caught/ lead led led
3、第三类不规则动词的原形、过去式和过去分词都不相同,如:begin began begun/ break broke broken/ grow grew grown/ ring rang rung/ wake woke / waked woken
此外还有少数不规则动词的过去分词与原形相同,如:come came come/ become became become/ run ran run
【练习】用所给动词的适当形式填空
(1)Tom and Mary ___________ (come) to China last month.
(2)Mike (not go) to bed until 12 o’clock last night.
(3)Mary __________ (read) English yesterday morning.
(4)There _________ (be) no one here a moment ago.
