动词的现在进行时态
1．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。
现在进行时的肯定句基本结构为be（am， is，are）+动词ing. 2．动词加ing的变化规则 1）一般情况下，直接加ing，
如：look - looking, climb - climbing, jump - jumping, play - playing, go - going , draw - drawing 2）以不发音的e结尾，去e加ing.
(see的e是发音的，所以不能去掉，要直接加ing。see - seeing ) 如：make - making, have - having, ride - riding, write - writing, drive - driving
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.(但是open却不属于这规则，而是直接加ing， open-opening) 如：run - running, swim - swimming, sit - sitting,
cut-cutting, hop - hopping, get - getting.
3．现在进行时的肯定句基本结构为be（am， is，are）+动词ing. be会随着与不同的人称搭配而产生不同的变化。 如：I am playing football. You are watching TV. We are having a class. He is climbing trees. She is playing with her cat. It is running in the park. They are going home.
把它们的变化编成一首顺口溜就好记多了！Look！
我用am， 你用are，Is 用在他，她，它，我们， 你们，他们全用are。
