一．动词ing形式的用法 

1.正在进行时中,谓语动词后加ing.  如:I'm playing football.   

2.一些特殊表达..如:  be good at doing sth

enjoy doing sth.

be busy doing

feel like doing

thank you for doing

do some cooking/cleaning/reading/shopping/washing

go swimming/fishing/shopping/skating/boating

二．动词现在分词由动词原形在词尾加ing构成，其规则如下：  

 1）一般情况下直接加ing    

think---thinking     sleep---sleeping                             

study---studying   speak---speaking                             

carry---carrying     say---saying    

2）以不发音的字母e结尾的单词，去掉字母e，再加ing

wake---waking    make---making    come---coming  take---taking      leave---leaving    have---having   3）以重读闭音节结尾，呈现“辅，元，辅”结构的动词，先双写末尾的辅音字母，再加ing 。初中学过的这类词有：begin，cut, get, hit, run, set, sit, spit, stop, swim, beg, drop, fit, nod, dig, forget, regret, rid, 等。 (visit 不是以重读闭音节结尾，不用双写) travel虽然重读第一音节，词尾音节不重读，但是现在分词仍要双写末尾辅音字母，然后再加ing ，如：travel---travelling.初中阶段此类词只有这一个。

4）以 y 结尾的动词 直接加 ing

carry—— carrying    enjoy—— enjoying

5）以ie结尾的动词，把ie改为y ，再加ing

die---dying     lie---lying 

要特别注意有些动词没有进行时态. 1、表示状态、思想、感情和感觉的动词，如：see, hear, love, know, want, hope, think等，没有进行时态。 2、当have/has作为“拥有”时，没有进行时态，但表示“开会，吃饭，玩得高兴”等意思时，可以用进行时表达。  I am having many books. （这是错误的句子）

 I am having a good time. （这才是正确的句子）
