5.语法知识——Do的用法其及一般疑问句的用法
do 这个词大体上从两方面来讲
1.作为行为动词,跟其他动词一样,如study, play等。他的意思是“做”等。

I often do sports on the weekend. 在周末我经常做运动。
I can do some kung fu. 我会一些功夫。
2.作为助动词(没有词义),也就是帮助主要动词构成否定和疑问等。
①否定形式do not =don’t 放于实意动词前。
如:We don't like bananas. 我们不喜欢香蕉。I don’t know.我不知道。
②一般疑问句形式
当句中没有Be动词、情态动词can,只有行为动词(实意动词)的时候,分以下四步骤
(1)、在句首加Do或Does,当主语是第三人称单数的时候用Does,其它都用Do
(2)、将人称变换,第一人称变第二人称(I→you,we→you,my→your,our→your),
第二人称变第一人称(you→I,you→we,your→my,your→our),
第三人称不变
即一变二,二变一,三不变
(3)、在句尾加问号“?”
(4)、肯定回答:Yes , 主语+do/does 否定回答:No, 主语+do/does+not.
如:Do you like apples? 你喜欢苹果吗?Do you want to be a teacher? 你想成为一个老师吗?
