现在进行时
现在进行时表示现在正在进行或发生但还未结束的动作或行为,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。
现在进行时可以一般分为四种基本句型结构:
1、 肯定句:主语+ be+动词ing+其它
例:He is watching TV. 他正在看电视。
2、 一般疑问句:Be+主语+动词ing+其它
例:Is he watching TV ? 他正在看电视吗?
3、 否定句:主语+be+not+动词ing+其它
例:He is not watching TV. 他不是正在看电视。
4、 特殊疑问句:疑问词+be+主语+动词ing+其它(如果问人称,则中间不出现主语)
例:What is he doing ? 他正在干什么?
在一般现在时中,一般动词后面加ing,特殊的变化规则如下:
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
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
