四．语法
本单元最重要的知识点就是现在进行时，下面主要对现在进行时做一个总结和复习。
现在进行时与一般现在时的区别：
一般现在时：例句：He likes pandas.
经常性的，习惯性的，客观真理，一般情况下的，有三单的形式。
现在进行时：例句：I am watching TV.
正在进行的，be doing
be:变色龙，am,is,are
doing:ing为现在分词的尾巴
动词加ing的方法：
① 直接加ing
例子：eating，doing, reading, singing
② 去e加ing
例子：writing, making, dancing
③ 双写加ing：一个辅音，一个元音。
例子：running, swimming, shopping
一般来说，重音在后面要双写，重音在前面不双写。但是这个辅音如果为x，比较特殊，不用双写，例如：relaxing。
还有一些较为特殊的"妖怪"。
例子：see要变为seeing，不用去e，直接加。
lie要变为lying，把ie变为y，再加ing。
die要变为dying，把ie变为y，再加ing。
现在进行时句子的变形：
例:（1）He is swimming.
改为否定句:He isn't swimming. 直接在be动词后加not。
改为一般疑问句：Is he swimming? 直接把be动词提前。
对swimming提问：What is he doing?
（2）She is running on the playground.
改为否定句：She isn't running on the playground.
改为一般疑问句：Is she running on the playground？
对running提问：What is she doing on the playground？
对on the playground提问：Where is she running?
