一．动词第三人称单数的变化规则
1、大多数动词在词尾加“S”在清辅音后发音为[s]，在浊辅音及元音后发音为 [z]。如：①stop －stops
[s] ; make－makes [s]
2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读[iz] 如：fly －flies [z]； carry －carries [z]
3、以“s, x, ch, sh”结尾的，在词尾加“es”，发音为[iz] 如：teach －teaches [iz]; watch－watches [iz]
4、以“o”结尾的动词，加“es”，读[z] 如：go －goes [z]
二. 动词变现在分词的变化规则:
1. 直接在动词原形后面加-ing 。如：read – reading cook – cooking talk – talking
2. 以不发音的字母e 结尾的动词把e 去掉加-ing 。如：write → writing make → making
3. 以一个辅音字母加一个元音字母结尾的重读闭音节单词, 要双写最后一个辅音字母再加-ing 。如： run → running cut → cutting swim → swimming
5）以ie 结尾的动词，把ie 改为y ，再加ing
die---dying lie---lying
