动词的形式：
一、 动词后面加上ing :
、现在进行时：表示某个动作正在发生或进行。它的构成方式是：
主语+be+动词ing〔现在分词〕形式，有时会要求自己加上be动词（is, am , are ）。句子中经常会出现look, listen, now……等词。
现在进行时的变化
肯定句式：主语+be( am, is, are)+动词ing+其它。
否定句式：主语+be(am, is, are) +not +动词ing+其它。
一般疑问句：be(am, is, are) +主语+动词ing +其它？
特殊疑问句：疑问词(what , where…)+be(am, is, are)+主语+动词ing +其它？
对现在进行时的特殊疑问句的回答，它不可以用yes或no直接作答，要根据实际情况回答。
练习：1. what are youdo) now? ieat) bread.
2. it’s nine o’clock.. my fatherwork) in the office.
3. look, the boyput) the plate on his finger.
4heclean) the classroom? no, he isn’t. heplay).
5. where is mak? herun) on the grass.
6. listen, whosing) in the music room? oh, marysing) there.
like(s), go , do some , 后面的动词加ing.
如：1. i like (play ) football, but my father likesplay) chess.
goswim).
二、动词后面加s/es. 这就有关一种时态：一般现在时。
一般现在时：表示经常性的事情。
时间状语：often经常， usually通常， always总是， every每个， sometimes有时，at…在几点钟。
它的动词变化与主语人称有关，只有肯定句中第三人称单数用动词三单（动词加s/es），其余动词均用原形。在否定句和问句中，因为有助动词do, don’t , does , doesn’t，所以后面的动词用原形。
三单变化： 多数在动词后加s play—plays like—likes
以s，x，sh，ch，o结尾的动词加es go—goes wash—washes watch--watches
以辅音字母加y结尾，把y改i再加es fly—flies study—studies
一般现在时的变化：
1、肯定句：主语（非三单）+动原+其它 / 主语（he , she ）+动词三单+其它。
2、否定句：主语（非三单）+don’t+动原+其它 / 主语（he , she ）+动原+其它。
3、一般疑问句：do +主语（非三单）+动原+其它 / does +主语（he, she ）+动原+其它。
4、特殊疑问句：特殊疑问词（what, where …）do +主语（非三单）+动原+其它。
特殊疑问词（what, where…）+does +主语（he , she ）+动原+其它。
