一般疑问句：Am/ Is/ Are + 主语+动词ing形式 (+sth)；
回答：Yes, 主语+am/is/are 或者 No, 主语+am/is/are
时间点：现在进行时一般与now, at the moment等连用。
时间段：如果在描述一段时间内都正在做且现在也在做的事情，可以用现在进行时，一般有时间段如these days, this week, this month等等
一般过去时态复习：
概念?：一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用。如：last?year,?last?week,?last?night,?yesterday等。
结构：
肯定句：主语+动词的过去式+其它
否定句：主语+did?not?(didn't)+动词原形+其它
一般疑问句的构成：?Did+主语＋动词原形＋其它？
回答：Yes, 主语+did/ No, 主语+didn't
区别：表示正在进行的发生的动作、表示过去某个时间里发生的动作或者存在的 状态
?主要用法：1.表示过去某一时间内（正在）进行的动作、或者表示在过去某个时间点发生的事情。
　　2.表示一动作正在进行时，另一动作同时正在进行.（复合句：如果主要动作和背景动作都是延续的或同时发生的，那么主从句的动词都可用过去进行时）
　 （1）用while连接（while只接doing）
例:My mother was cooking while I was doing my homework.(可以持续动作时态一致)
（2）when表示（when可以接doing或did，when后动作时间长，用doing，时间短，用did）

过去进行时态
概念：?表示过去某一时刻或过去某一阶段时间正在进行的动作??(不强调是否完成）
?结构：??was?/?were?+?doing??
一般疑问句及答语：Was/Were+主语+doing+其它 ？
答语：Yes,I was./No,I wasn't
过去进行时与现在进行时的区别：??
?两者都表示动作正在进行，只是时间有别,现在进行时表示现在或现阶段正在进行的动作。过去进行时则表示在过去的某一时间点或过去某一阶段正在进行的动作。
过去进行时与一般过去时的区别：一般时过去表示的是过去经常发生的动作或状态。而过去进行时表示的是过去某一时刻正在进行的动作。因此，它们在使用的时间词语上有着比较明显的区别。那就是，一般过去时所指的过去时间却比较笼统，而过去进行时所指的过去时间则比较具体，并含有“当时正在做某事”的意思。过去一般时表示的某个动作已经完成，而过去进行时则不一定完成。
