用法
基本用法
表示过去某个时刻发生的动作或存在的状态,且和过去具体时间连用。(yesterday,last year/month/week, in+年份,月份;on+过去某一天,…ago等)。e.g.: I lived in Beijing three years ago.三年前我住在北京。They repaired the car last night.他昨天晚上修理了汽车。Finally Mr. Smith caught the thief yesterday.昨天史密斯先生最终抓住了小偷。
表示过去经常发生的动作,常和always,often等词连用。 Tips:英语中的不规则动词才是重点中的重点,一般来说常用的动词都是不规则动词的。e.g.: When i was at collage,i always went to the library.当我还在上大学的时候,我经常去图书馆。When she was a girl,she often swam this river.当她还是小女孩时,她经常来这河里游泳。 Tips:经常有时候关于频率副词的问题,实际上频率副词always,often,never,sometimes董事可以用于各种时态的,不一定就要用于一般现在时态当中。
特殊用法
表示过去常常发生某事时,可常用used to do和would do两个词组,但两词有区别。 e.g.:I used to smoke,but i have stopped.我过去常吸烟,但现在已经戒了。(表示过去常常发生,现在不发生了。) I would smoke,and i smoke sometimes.我过去常吸烟,现在有时还吸。(表示过去常常发生,现在不一定不发生。)
