现在进行时态

二．现在进行时。

一．定义：现在进行时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。

二．现在进行时基本结构为be+现在分词（动词ing.）形式： be + verb +ing eg: I am(not) doing my homework. You/We/They are(not) reading. He/She/It is(not) eating.

动词加ing的变化规则

1)一般情况下，直接加ing，如：cook-cooking study—studying,

2)以不发音的e结尾，去e加ing，如：make-making, taste-tasting 注：see—seeing,

3)如果末尾是一个元音字母和一个辅音字母，双写末尾的辅音字母，再加ing。

如：run-running, stop-stopping,swim—swimming，shop---shopping,

但不包括以一个元音字母加上”w,y”结尾的词，（如：draw--drawing）

三．现在进行时的变化：

1.变否定句：在be后加not。如：They are not reading。

2.变一般疑问句：把be提前句首,大写，句尾加问号。如：Are they reading?

Yes, they are. No, they aren’t.

3.变特殊疑问：疑问词+ be + 主语 + 动词ing?

注：但疑问词当主语时其结构为：疑问词+ be + 动词ing?

四．时间状语： now / right now / at the moment(此时此刻) / at 7 o’ clock

/ Look ！/ listen ！/

Where is + 主语，后一般用进行时态 .

五．表状态或感觉的动词，不能用现在进行时：be, have, love, like, know, leave…如不表示状态感觉时可用。

六．现在进行时与always, forever, constantly连用时，表示“赞扬，埋怨”

等感情色彩

如：my granny is always losing keys.(-----老是丢钥匙。)
