二、请看下面两组句子，注意区分他们的配合点和不合点.
I go to school every day.
I don't go to school every day.

He doesn't go to school every day.
Do you go to school every day?
Yes, I do. (No, I don't)
Does he go to school every day?
Yes, he does. (No, he doesn't)
注：
1）第三人称单数用了 does 前面就不必动词的s形式了,而用动词原形..
2）变成疑问句,要在句首加"do" does ; 变成否认句, 要在动词前面加"do not ,does not", 可以简写为"don't", doesn’t.
