一般现在时 一般现在时第一节——基本知识 一般现在时表示经常重复性的动作或是存在的状态。 例如：他喜欢睡觉。He likes sleeping.

He worked in a factory in 1986. I met her in the street the day before yesterday. He often swam in the river when he was young. （2）过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有，at that time/moment, (at) this time yesterday (last night/Sunday/week…), at+点钟+yesterday (last night / Sunday…)，when sb. did sth等时间状语从句。 What were you doing at seven p.m. yesterday? I first met Mary three years ago. She was working at a radio shop at the time. I was cooking when she knocked at the door. （3）一般过去时往往表示某一动作已经完成，而过去进行时却表示动作在持续或未完成。如： I saw you while you were speaking to the teacher. 注意：有的过去时间状语既可用于一般过去时，也可用于过去进行时，但含义不同。如： She wrote a letter to her friend last night.（信写完了） She was writing a letter to her friend last night.（信不一定写完）
