现在进行时

1.现在进行时的功能

(1)表示现在(说话时)正在发生的动作,一般和now,right now,at this moment等连用。

(2)也可以表示当前一段时间正在发生的事情(说话时不一定进行),常与this week,this month,these days(这些天)连用。

如:We are writing a book this month.这个月我们正在写一本书。

2.现在进行时的构成

肯定句:主语+be动词(am /is /are)+动词ing+其他。

如:They are playing basketball now.他们现在在打篮球。

He is cleaning the classroom now.他正在打扫教室。

I am reading a book.我正在读一本书。

否定句:主语+be动词(am /is /are)+not+动词ing+其他。

一般疑问句:Be动词+主语+动词ing+其他。

肯定回答:Yes,主语+be动词(am /is /are)。

如:Are they playing basketball now.他们现在在打篮球吗?

特殊疑问句:特殊疑问词+一般疑问句

如:What are they playing now?他们现在在玩什么?

但是,当疑问词为主语时,其结构为:疑问词+ be + 动词ing?

动词加ing的变化规则

1.一般情况下,直接加ing,如:cook-cooking

2.以不发音的e结尾,去e加ing,如:make-making, taste-tasting
