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 ofa. They're her. 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根本结构及谓语局部的构成,然后补全结论局部所缺内容。【观察】肯定句否认句I / We / They have a baeball.I / We / They dont have a baeball.Bob / He / She ha a brother.Bob / He / She doent have a brother.一般疑问句简略答语Do you / they have a baeball Ye, I / we / they do.No, I / we / they dont.Doe Bob / he / he have a brother Ye, he / he doe.No, he / he doent.【结论1】通过观察上面的例子,我们可以出含有动词have(有)的各种句式的根本结构:1. 肯定句:主语 + have / ha + .2. 否认句:主语 + don't / doen't + have + .3. 一般疑问句:助动词Do / Doe + 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 / ha (有)的一般现在时的肯定句变成否认句或一般疑问句时,要借用助动词do或doe,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Doe开头的一般疑问句进行简略答复,可以用“Ye, 主语(人称代词) + do / doe.”或“No, 主语(人称代词) + don't / doen't.”。Key: 1. ha; have2. doe; do 【运用】根据对话内容及括号内所给词的提示填空。A: Hi, Bob!
