三年级上册暑假自学课（译林版三起） Unit 4 This is my friend 语法易错+巩固练习 语法易错01 1.be动词的用法 一、be动词的用法 在一般现在时中，be动词有三种形式：am、is、are，一般意为“是”。根据句子中不同的人称和数量来选择相应的be动词形式。be动词与人称的搭配如下图。 人称代词（主格） be动词 I am you/ we/ they are he/she/it is 二、一般现在时含be动词的肯定句结构： 主语 + be动词 + 表语 例：①I'm Mike Black.我是迈克·布莱克。 ②We are students.我们是学生。 ③It is a cute dog.它是一只可爱的狗。 三、be动词的缩写形式： 通常情况下, am缩写为'm, is缩写为's, are缩写为' re. 如: I am = I'm; He is = He's; You are = You're. 易错点提示 易混淆be动词与人称代词的用法，用法口诀如下： ☺我(I)用am,你(you)用are, is用于他(he)、她(she)、它(it) 单数（单数名词）用is, 复数都用are，勿忘be的三变化。 知识演练01 一、用am、is或are填空。 1.
