专项：现在进行时语法
一、概念：表示现在正在进行或发生的动作，也表示现在正在进行的事情。
二、基本结构：
1> 肯定句:主语+be动词（am,is,are）+现在分词+其它
例如：1、I am +V-ing.例题：I am reading.
2、You/We/They/复数名词 are +V-ing.例题：They are watching TV.
3、She/He/It/Tom is +V-ing.例题：She is swimming.
2>否定句:主语+be not +现在分词+其它(即在be动词后直接加not)
例如：1、I am not reading.
2、They are not watching TV .
3、She is not swimming.
3>一般疑问句：be+主语+现在分词+其它（即将be动词提前，I和we变成you, my变成your）
例如：1、 Are you reading ?
2、 Are they watching TV ?
3、 Is she swimming ?
4>特殊疑问句：What+be动词+主语+现在分词？
例如：What are you doing?
三、动词的现在分词的构成
1、一般动词的词尾直接加“ing”。如: do---doing; jump—jumping; sleep---sleeping
2、以不发音的e结尾的动词，去e加“ing”。如：have---having；write---writing; dance--- dancing
3、一些以重读闭音节结尾而且末尾只有一个辅音字母的动词，要双写辅音字母，然后加“ing”。小学阶段常见的有六个：
sit-sitting，swim-swimming， run-running，let-letting，put-putting，get-getting
四、通常在句子中有以下的词：now,look,listen，可表示现在进行时。
例如：1. The students are drawing pictures now.
2. Listen! She is singing .
3. Look! Mr Li is riding a bike.
