【意义】：表示现在正在进行或发生的动作；也可表示当前一段时间内的活动或现阶段正在进行的动作。
【构成】：be +现在分词（v. +ing）
【口诀】：现在进行要注意，有be还有ing，be的形式看主语，
双写、去e要留意
【结 构】
主语+ be（am / is / are）+动词的-ing形式。
肯定式
疑问式
否定式
I am working.
Am I working?
I am not working.
You are working.
Are you working?
You are not working.
We are working.
Are we working?
We are not working.
They are working.
Are they working?
They are not working.
He(She,It) is working.
Is he(she,it) working?
He(She,It) is not working.
肯定句形式： 主语+be动词+动词ing+其他.
I + am 动词ing. 如：I am reading (read) a story (故事)book now.
She/He/It + is 动词ing. 如：Tom is reading (read) a story book now.
We/You/They + are动词ing. 如：They are reading (read) a story book now.

直接在be（am, is, are）之后加not，其余照抄。
如: I am not reading ( not read) a story book now.
Tom isn’t reading ( not read) a story book now.
They aren’t reading ( not read) a story book now.
一般疑问句：be动词+主语+动词ing+其他？
直接将be（am, is, are）提到主语之前，其余照抄。
如：Is Tom reading (read) a story book now?
Are they reading (read) a story book now?
特殊疑问句：疑问词+be动词+主语+动词ing+其他？
首先分析划线部分的意思，确定用哪个疑问词（what, where, who, whose, how, how many, how much, what colour, what … doing, where … going, what … do）,然后再将原句变为一般疑问句形式（即将be动词提到主语之前，其余的不变）。如：What time is Tom reading(read) a story book?
Where are they taking(take) pictures(拍照)?
