现在分词变化规则： 1 .一般情况下直接加ing

think---thinking sleep---sleeping study---studying speak---speaking 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 dance----dancing ride----riding write---writing ※注意※ 这里的e必须不发音，若发音，则不能去掉，如see→seeing

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

[要判断一个单词是否是重读闭音节，必须同时满足下列三个条件：] １、这个音节必须重读；

２、这个单词结尾必须是“辅元辅”，即“辅音字母＋元音字母＋辅音字母”；

３、在这个“辅元辅”中的元音字母必须发短音。

stop---stopping sit---sitting run---running forget---forgetting begin---beginning

4. 以ie结尾的动词，把ie改为y ，再加ing lie---lying

以上规则用一句话概括成的口诀就是：直接 双写 去e，ie变y ing
