助动词do的四种用法
助动词do的四种用法
助动词 do 主要有以下四种用法:
1、构成一般疑问句
当句子的谓语是实义动词,且没有 be 动词、情态动词等时,需要在句首加助动词 do 来构成一般疑问句。
例如:“You like music” 变为一般疑问句就是“Do you like music?”
注意,当主语是第三人称单数时,要用 does,且其后的动词要用原形。
比如:“He works hard” 变为一般疑问句为“Does he work hard?”
2、构成否定句
当句子的谓语是实义动词,且没有 be 动词、情态动词等时,在实义动词前加 don't 或 doesn't 来构成否定句。
例如:“I play football” 变为否定句为“I don't play football” ;“She studies English” 变为否定句为“She doesn't study English”
3、加强语气
在肯定句中,do 可放在动词前,表示强调,意为“确实,的确”。
例如:“I do like this book” (我确实喜欢这本书。
)
4、代替前面出现的动词
为避免重复,do 可以用来代替前面出现过的实义动词。
例如:“I like music and my sister does too” (我喜欢音乐,我妹妹也喜欢。
)需要注意的是,在使用助动词 do 时,要根据句子的主语和时态来正确选择形式,同时要注意句子的结构和语法规则。
关于助动词do讲义人教版英语七年级上册
人教版英语七年级上册关于助动词do\does的正确运用知识总结与练习进入第五单元后,引入了助动词do以及does,很多学生便无法区分什么时候用助动词,什么时候用be(is\am\are)动词。
接下来,我们就从一般疑问句、否定句、特殊疑问句三个方面来分别讲一讲。
一、一般疑问句。
一般疑问句是用Yes \ No来回答的疑问句,前面的四个单元我们见的比较多,那个时候是用be动词来引导的。
例如:Are you Tom? \ Is she Grace?\ Are they Tom and Jerry?\Is this your ruler? \ Are those his dictionaries? \ Is Alice your aunt? \ Is the pencil in the pencil case? \ Are the books in the bookcase?从第五单元Unit 5 Do you have a soccer ball?开始,引入了助动词引导的一般疑问句,例如:Do you have a basketball? \ Does she have a sports collection? \ Do you like apples? \ Does she like strawberries?be动词引导的一般疑问句和助动词引导的一般疑问句,最本质的差别就是看有没有动词,如果有,就用助动词来引导,如果没有,就用be动词来引导。
练习题:根据句意,用适当的be动词(is\am\are)或者助动词(do\does)填空。
1、_______ the boy your brother?2、_________ they your parents?3、_________ you have a baseball bat?4、_________ Mr. Wang your English teacher?5、_________ Tom and Jenny friends?6、_______ Grace your classmate?7、_________ the boy like his school ?8、_________ the girl play sports every day?9、________ you from China?10、________ your cousin watch TV every day?解题思路:观察所有的句子,找出带有实义动词的,就用助动词Do或者Does,如果没有实义动词的,就用be动词(I 用am ,you用are ; is单数,复数are。
do和does在句子中的用法
do和does在句子中的用法一、do和does的基本用法do和does分别是英语中常见的助动词,用于构成疑问句、否定句以及强调句。
