do和does的用法助动词do与does与人称代词搭配一致口诀（一）变句型，先观察主语为一、二、（三复），陈述句中动用原。

一般疑问do句首，否定don’t实动前。

（二）若是主语为三单，陈述句中动变形。

一般疑问也简单，does放在句子前。

否定doesn’t实动前，主动出现动还原。

注：一、二、（三复）指的是第一、第二人称单复数，第三人称复数。

动用原指动词用原形，实动指实义动词。

do 这个词（does是第三人称单数形式），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。

如：We usually do our homework in the afternoon.He does his homework in the evening.2.作为助动词，也就是帮助主要动词构成否定和疑问等。

We don't like bananas.Do you like apples?Does he like English?He doesn't like swimming.上面有一句He does his homework in the evening.要是变成否定句就成了这个样子：He doesn't do his homework in the evening.这里加上了助动词doesn't，而原来的主动词does变成原形do了。

作为助动词的do和does是没有词义的，它们在句中的构成一般现在时的疑问句和否定句.Do用于主语第一人称，第二人称和第三人称复数形式的句中，does用于主语第三人称单数的句中。

Eg. Do you want to be a teacher? 你想成为一个老师吗？Do his friends go to park every day? 他的朋友们每天都去公园吗？I don’t like him. 我不喜欢他。

Where does Tom come from? 汤姆来自哪里？I do n’t know.我不知道。

He doesn’t live here. 他不住在这儿。

will/can/could/would/should/shall 等助动词后面加be 其他时候, 第一人称I后面用am第二人称, 复数, 用are单数用is...三．选词填空。
