2、当前一段时间内的活动或现阶段正在进行的动作。E.g. They are working these days. 3、某些动词的现在进行时，表预定的计划或即将发生的动作。E.g I am coming. 其结构为be+现在分词. 现在分词的变法有 1、一般在动词词尾加上-ing ,E.g. jump 2、以不发音字母e结尾的动词，先去e，再加-ing. E.g have write 3、.以重读闭音节末尾只有一个辅音字母结尾的词，它前面是单个元音字母时要先将 词尾的辅音字母双写，再加上-ing. E.g. sit put 其句式变换都在be上做文章。 E.g. He is buying a bike. Is he buying a bike? He isn’t buying a bike. 一般由look,listen,now, at this moment等时间状语做标志。
Were you cooking at that time？ 那时，你在做饭吗？ 现在进行时的用法： 其结构是助动词be的过去形式is/are/am +v-ing.
其句式变化仍然要在be上做文章。
现在（说话的瞬间）正在进行或发生的动作，强调“此时此刻”。E.g. He is reading . They are talking now.
过去进行时 其结构是助动词be的过去形式was/were +v-ing.
其句式变化仍然要在be上做文章。E.g. We were working in class. We weren’t working in class. Were you working in class?

5. 表示渐变的动词有：get, grow, become, turn, run, go, begin等。 The leaves are turning red. It's getting warmer and warmer.

2） 过去某阶段持续进行的动作 What were you doing during the holiday? 另外，在复 合句中，若主要动作和背景动作是同时发生的，那么主从句都可用过去进行时e.g. Jenny was reading while Danny was writing.
3) 常用的时间状语 过去进行时常与过去某一特定时间的状语连用，如 last night, at that time, at noon yesterday, last Sunday 等。 也有时没有时间状语，要通过上下文的暗示来确定用过去进行时。E.g. The students all worked hard. Everyone knew what he was working for.
