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。
人教英语七上Unit 3 be动词现在时、一般疑问句专练
同步语法思维导图-Unit 3 be动词现在时一般疑问句【知识导图】【要点拓展】1.当把含有be动词的肯定句变为一般疑问句时，通常将I变为you，be动词也要相应地变为are。
同样，肯定句中的形容词性物主代词my，变一般疑问句时要改为your。
I am a teacher.我是一名教师。
Are you a teacher?你是一名教师吗？（I改为you，am改为are）This is my book.这是我的书。
Is this your book?这是你的书吗？（my改为your）2.一般现在时态下，be动词引导的一般疑问句的回答：Are you...?Yes, I am.No, I am not.（you是第二人称单数）Are you...?Yes, we are.No, we are not/aren't.（you是第二人称复数）Are they...?Yes, they are.No, they are not/aren't.Is she/he/it...?Yes, she/he/it is.No, she/he/it is not/isn't.Is this/that...?Yes, it is.No, it is not/isn't.Are these/those...?Yes, they are.No, they are not/aren't.【奇思巧计】含be句子变问句，把be提前没问题；yes和no要搞清，回答要用代词替；主语的数决定be，结尾定把问号记。
【同步检测】1．—________ you Li Fen?—No, I ________ not.【答案】Are am【解析】【分析】【详解】句意：——你是李芬吗？——不，我不是。
结合句意，表示是，用be动词，主语是you，be动词用are；主语是I，be动词用am，故填Are；am。
2．— ________ Mr. Green very busy?—Yes. He ________.【答案】Is is【解析】【详解】句意：——Green先生很忙吗？——是的，他很忙。

助动词dodoes的练习
be动词，情态动词，助动词do/does的用法区别及练习1. 由连系am，is，are构成的句子：变一般疑问句时把am，is，are提到句子的前面，句尾用问号即可。
变否定句时直接在am，is，are后面加not即可。
例如：肯定句:He is a student.一般疑问句: Is he a student?否定句: He is not a student.画线提问: 对he提问: Who is a student?对 a student 提问: What is he? or What does he do?2. 由情态动词can, may, should等构成的句子: 变一般疑问句时把can,may,提到句子的前面,句尾用问号即可.变否定句时直接在can,may,后面加not即可. 例如:肯定句: She can swim.一般疑问句: Can she swim?否定句: She can not swim.画线提问: 对she提问: Who can swim?对swim提问: What can she do？3. 由行为动词构成的句子: 需要加助词do或does. 变一般疑问句时把do/does放在句子前面. 变否定句时把don’t/doesn’t放在动词的前面。
要注意观察动词的形式并对号入座。
一般疑问句和否定句的动词三单式都要变回原型。
play-----do plays-----does例如:肯定句: They play football after school. He plays football after school.一般疑问句: Do they play football after school?
