Unit 5～6 语法专题2023-2024学年人教版七年级英语上册

Unit 5~6重点语法 1. 动词have的一般现在时 英语中有多种时态，当表示主语现在的状态时，要用一般现在时。我们在前面已经学习过be动词的一般现在时，如：They're on the sofa. They're hers. I'm fine.等。本单元我们学习含有动词have (有)的一般现在时。 动词have (有)用于一般现在时，其形式要随主语的变化而变化。仔细观察下面表格中例句的各种句式的基本结构及谓语部分的构成，然后补全结论部分所缺内容。 【观察】 肯定句 否定句 I / We / They have a baseball. I / We / They don’t have a baseball. Bob / He / She has a brother. Bob / He / She doesn’t have a brother.   一般疑问句 简略答语 Do you / they have a baseball? Yes, I / we / they do. No, I / we / they don’t. Does Bob / he / she have a brother? Yes, he / she does. No, he / she doesn’t. 【结论1】 通过观察上面的例子，我们可以总结出含有动词have(有)的各种句式的基本结构： 1. 肯定句：主语 + have / has + ... 2. 否定句：主语 + don't / doesn't + have + ... 3. 一般疑问句：助动词Do / Does + 主语 + have + ...? 【结论2】 1.  在含有动词have (有)的一般现在时的肯定句中，当主语是第三人称单数时用________，当主语是其他形式时用________。 2. 将含有动词have / has (有)的一般现在时的肯定句变成否定句或一般疑问句时，要借用助动词do或does，且have要用原形。当主语是第三人称单数时，助动词要用________，当主语是其他形式时，助动词要用________。 3. 对Do或Does开头的一般疑问句进行简略回答，可以用“Yes, 主语(人称代词) + do / does.”或“No, 主语(人称代词) + don't / doesn't.”。 【运用】 1. 根据对话内容及括号内所给词的提示填空。 A: Hi, Bob!
