本次课要求
1.熟练掌握动词三单变化规则 2.掌握并会使用一般现在时 3.练习变否定和疑问 4.答题步骤：①找标志词或看句意是否为一般现在时 ②找主语判断是否为三单（he,she,it,人名，地名） ③是三单就变，不是就不变
8. The cat usually__c_a_t_c_h_e_s_ the mouse.(catch) 9. I __d__o___ my homework everyday.(do) 10. China __i_s____a big country. (be) 11. The earth[地球]__g_o_e_s__around the sun.(go) 12.

have→has、be→is
扩展 7.一般现在时变否定句、一般疑问句
（1）主+be+其他
Eg: He is a worker.
否:主+be+not+其他 [am not/isn’t/aren’t]
He isn’t a worker.
疑:Be+主+其他+？(提前)
Is he worker?
（2）主+实意动词+其他 Eg: she works in a factory.
Simple present
3.构成
(1)主语+be动词+其他 I am a teacher. He is a student. They are my parents.
be动词用法口诀：
我(I)用am, 你(you)用are， is跟着他(he)，她(she)，它(it)。
我们(we)你们(you)他们(they)都用are
谓语动词要用第三人称单数形式
单数 第一人称
复数 第二人称 单复数同形
单数 第三人称
复数
主语
I（我） we（我们） you（你/你们） he（他）；she（她）；it（它） they(他们)
变化规则
5.动词三单变化规则
(1)一般动词直接在词尾加s (2)以s,x,ch,sh结尾的动词在词尾加es (3)以辅音+y结尾，变y为i，再+es； (4)特殊变化：go→goes、do→does、
[do为助动词，后边的动词要打回原形]
否:主+don’t/doesn’t+动词原形+其他 疑:Do/does+主+动词原形+其他+？(提前)
She doesn’t work in a factory. Does she work in a factory?

总结
变疑问，往前提，句末问号莫丢弃。 变否定更容易，be后not莫忘记。 变疑问，放句首，首字大写要牢记。 如果没有be动词, 就要借助do/does。
