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.,5,受累问一句,你几年级?,3,是助动词,do是第一第三人称的时候用的,does是第三人称单数的时候,就是he she it 的时候用的,助动词没有实意,do应该是做的意思吧,2,do
[duː],2,助动词:1)构成一般疑问句,例如: Do you want to pass the CET?你想通过大学英语测试吗? 2) do + not 构成否定句,例如:I do not want to be criticized.我不想挨批评。3)构成否定祈使句,例如:Don't go there. 不要去那里。说明:构成否定祈使句只用do,不用did和does。4)放在动词原形前,加强该动词的语气,例如...,2,这个问题……我举几个简单的例子吧……
1、疑问句中实意动词的助动词,放在句首,表疑问。
eg: Do you go home?
2、肯定句中的强调,放在实意动词之前,“的确,确实,实在”,表强调。
eg: he does like the book.
3、做实意动词的话就是“做”的意思,很宽泛……
eg: I do the job well...,2,助动词,do用于复数或者非第三人称,does用于第三人称单数。,1,1.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:
