第1讲一般现在时，一般过去时
考点分析：
1.行为动词第三人称单数形式，带行为动词变成否定，一般疑问句及特殊疑问句形式
2.一般过去时的肯定，否定，一般及特殊疑问句形式。
重点：1．一般现在时
2.一般过去时
难点：
1．一般现在时行为动词的第三人称单数形式，否定，一般疑问及特殊疑问句形式
2. 一般过去时行为动词过去式，否定，一般疑问及特殊疑问句形式
一．带行为动词的一般现在时
考点一：
（一）带行为动词的一般现在时，行为动词要根据主语人称而做变化。当主语是第三人称单数时，行为动词必须要变成第三人称单数形式；当主语是非第三人称单数时，行为动词不用作变化。
如：I often go to school by bus .
He often goes to chool by bus .
1.动词原形变成动词第三人称单数形式变化规则：
2.1 一般情况下行为动词后面直接加 s
He ofen play s football on Sunday .
2.2 以s,x,h,ch,sh 结尾的，在行为动词后面直接加es
Tom usually watch es TV at 7:00.
2.3 辅音加 y 结尾的，把 y 改为 i 再加es
My mother worr ies about my English .
2.4 不规则变化
She always has lunch at 12:00.
【随堂练习】
1.Tom and Lily often _________( have ) lunch at 12:00.
2.I always __________( ride) to school .
3.My father often _____________( ride ) to work .
4.My sister often _____________( watch ) TV after lunch .
5.Jim always ________________( worry ) about his work.
6.The cat ______________( like ) to eat fish .
7.She usually ______________( have ) breakfast at 7:00.
考点二:
行为动词的一般现在时陈述肯定句变成否定句，要借助否定形式助动词don’t(do not), doesn’t(does not)
当主语是非第三人称单数时，在行为动词前加don’t (do not)
I ofen play football on Sunday .
I don’t ofen play football on Sunday .
当主语是第三人称单数时，在行为动词前加doesn’t(does not)
Tom usually watch es TV at 7:00.
Tom doesn’t usually watch TV at 7:00.
当加了助动词后，后行为动词必须要变为原型
【随堂练习】
1. Tom and Lily __________________ ( not have ) lunch at 12:00.
2.My father _______________________ (not ride ) to work .
3.Jim __________________________ (not worry ) about his work.
4.The cat ________________________ (not like ) to eat fish .
考点三:
行为动词的一般现在时陈述句变成一般疑问句，要在句首加助动词do ，does，
当主语是第三人称单数时，要在句首加助动词do；
当主语是非第三人称单数时，要在句首加助动词does .
I ofen play football on Sunday .
Do you ofen play football on Sunday ?
--Yes,I do./ No, I don’t.
Tom usually watch es TV at 7:00.
Does Tom usually watch TV at 7:00 ?
--Yes,he does./No,he doesn’t.
【随堂练习】

___________________________________________________________________
2.My sister often watches TV after lunch .
___________________________________________________________________
3.Jim always worries about his work.

4.She usually has breakfast at 7:00.
考点四：

一般疑问句：Does Tom usually watch TV at 7:00 ?
Who does usually watch TV at 7:00 ?
What does Tom usually do TV at 7:00 ?(划了行为动词的，后用do代替)
