Unit 5 语法思维导图及专练-2023-2024学年七年级英语上册基础知识专项讲练（人教版）

Unit 5 Do you have a soccer ball？（语法讲练） 【知识导图】 【要点拓展】 1.have意为 “有”。一般现在时的句子中,当主语是第三人称单数时,谓语动词用has;当主语是第一、二人称成第三人称复数时,谓语动词用have。 Jim has three rulers.古姆有三把尺子。 We have two English teachers我们有两位英语老师。 2.含有实义动词have的句子变否定句或一般疑问句时,需要借助助动词do或dos. (1)否定句结构是:主语+do not/don’t (does not/doesn’t) + have+其他 ①主语是第一、二人称成第三人称复数时,句中实义动词have前需要加don’t或do not。 ● I have a basketball.我有一个蓝球。→I don’t /do not have a basketball.我没有篮球。 ②主语是第三人称单数时,句中实义动词has前需要加doesn’t或does not,并将第三人称单数形式has变为have。 She has a good memory.她的记性很好。→She doesn’t /does not have a good memory.她的记性不好。 (2)一般疑问句结构是:Do/Does +主语+have+其他? ①主语是第一、二人称或第三人称复数时,句中主语前需要加do。 You have some pets.你有一些宠物。→Do you have any pets?你有什么宠物吗? ②主语是第三人称单数时,句中主语前需要加does并将第三人称单数形式has变为have。 He has a volleyball.他有一个排球。→Does he have a volleyball?他有排球吗? ③一般疑问句的答语 肯定回答:Yes，主语+do/does. 否定回答:No，主语+don’t/doesn’t. —Do you have a good friend?有好朋友吗? —Yes, I do.是的,我有。 —Does Alan have a green schoolbag?艾伦有绿色书包吗? —No. he doesn’t.不,他没有。 【奇思巧计】 have/has表示“有”，随着人称来改变。 I、we、you非三单，have紧紧跟后边； 疑问就把Do放前，否定don't动前站。 he、she、it是三单，定把is勤召唤； 疑问Does加动原，否定doesn't动原前。 【同步检测】 一、单项选择 1．She ________ a computer.
