1.be动词的变化。否定句：主语+be+not+其它。如：Heisnotaworker.他不是工人。

一般现在时的动词形式
一般现在时主要由动词原形表示，但第三人称单数后的动词词尾有所变化。第三人称单数动词词尾的变化有几种形式： 一般情况加-sreads,says,takes 以ch,sh,s,x,或o结尾的词加-esteaches,washes,goes,misses,mi xes 以辅音字母加y结尾的词变y为i再加-esstudies,cries,carries
一般现在时：表示站在“现在”这个时段叙述一般情况下发生的事情或状态,经常性或习惯性的动作。用法：（1）Be型句子（即句子里动词为am或is或are）以be为助动词，注意主谓搭配
例：Heisateacher.→Isheateacher?Yes,heis./No,heisn’t→Whatishisjob?
Iam/Youare/Heis/Sheis/Itis/Weare/Youare/Theyare
(2)行为动词句子（do型）
Ⅰ主语为第一，第二人称及复数，助动词为do(don’t).
MyparentslikewatchingTVintheevening.→DoyourparentslikewatchingTVintheevening?Yes,theydo./No,theydon’t.→Whatdotheydointheevening?
Ⅱ若人称为第三人称单数，助动词为does(doesn’t),肯定句(仅肯定句)时动词要有变化，否定句与疑问句动词不变（基本同名词复数变化）与上面的一组句子比较。
MyfatherlikeswatchingTV.→DoesyourfatherlikewatchTV?Yes,hedoes./No,hedoesn’t.→Whatdoesyourfatherdointheevening?
一般现在时动词口诀:肯定句：单数开头S形式，复数，你我用原形
否定句：单数开头doesn’t加动词，复数、你我don’t加动词
一般疑问句：单数Does××加动词，复数、你我Do××加动词
2.第三人称单数的动词变化规则
（1）多数动词直接加s:runsgetslikescolletstakesplaysclimbs…….
（2）结尾是s,x,sh,ch,o,前为辅音字母,结尾加es:watchesteachesgoes doeswashescrossesmixes
（3）动词末尾y前为辅音:将y改i加es:study→studiesfly→flies y前若为元音则直接加s:buyssays
