初一英语一般现在时讲解及其练习

1定义：表示通常性、规律性、习惯性的状态或者动作（有时间规律发生的事件）的一种时间状态。

2基本结构

A.如果谓语动词是实义动词的结构

结构：肯定式:主语+动词原形/动词的第三人称单数

否定式:主语+助动词don't/doesn't +动词原形+其他

疑问式:Do/Does+主语+动词原形+其他

简略回答:(肯)Yes,主语+do/does (否)No,主语+do/does not

缩写形式: don't == do not doesn't ==does not

注意：have的第三人称单数为has

1）be动词的第一人称单数为am，第三人称单数为is，其他人称为are

Be动词顺口溜用法：我用am ，你用are ，is 用于他，她，它, 单数is，复数are.

肯定式:主语+ am /is/are +其他

否定式:主语+ am/is/are +not + 其他

疑问式:Am /Is /Are + 主语+ 其他?

简略回答: (肯) Yes,主语+ am/ is /are (否) No,主语+ am /is/are not

缩写形式: I'm == I am That's ==That is We're ==We are What's== What is

You're == You are Who's == Who is They're ==They are Where's ==Where is He's

==He is She's =She is It's == It is isn't==is not aren't==are not

疑问句型

写出下列动词的第三人称单数：
