现在进行时及过去进行时讲解及练习

现在进行时

一、意义——当表示现在正在进行的动作或正在发生的事。

时间标志——now，句前的look ,listen

二、构成:be (am, is ,are )+动词现在分词-ing形式

肯定句：主语+ be + 现在分词V-ing (+ 其他)

否定句：主语+be+not+动词-ing +其他.

I’m not doing my homework now.

一般疑问句：Be+主语+动词-ing +其他

Are you doing your home work now

Yes, I am . No , I’m not .

特殊疑问句：特殊疑问词+be+主语+动词-ing+其他

三、现在分词的构成：

(1)一般在动词末尾直接加ing,

(2)以不发音字母e结尾的动词，先去掉e,再加ing，

如make →making dance → dancing跳舞write → writing写have → having ride → riding 骑come → coming来

以重读闭音节结尾的动词，中间只有一个元音字母，词尾只有一个辅音字母，应双写末尾的辅音字母，再加ing, 如：putting running beginning stopping swimming shopping jogging sitting getting forgetting letting
