知识点总结
动词的形式:
一、 动词后面加上ing :
①、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 you _________(do)now? I ___________(eat) bread.
2. It’s nine o’clock.. My father_______________(work) in the office.
3. Look, the boy____________(put) the plate on his finger.
4. __________he__________(clean) the classroom? No, he isn’t.He____________(play).
5. Where is Mak? He___________(run) on the grass.
6. Listen, who___________(sing) in the music room? Oh, Mary___________(sing)there.
②like(s), go ,do some , 后面的动词加ing.
如:1. I like (play ) football, but my father likes (play) chess.
2.Let’s go (swim).
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。
