新人教版（2024）七年级上册英语语法Unit 1 You and Me 语法基础 初中英语中，be动词主要用于表示主语的状态、存在、属性或身份等。be动词有多种形式，主要包括am、is、are、was、were以及它们的否定形式am not/isn't/aren't和过去式的否定形式wasn't/weren't。 一、基本形式与主语搭配： am：用于第一人称单数（I）的现在时态。 例如：I am a student. is：用于第三人称单数（he, she, it）的现在时态以及单数名词或不可数名词作主语时。 例如：He is tall. The book is interesting. are：用于第一人称复数（we）、第二人称单复数（you）和第三人称复数（they）的现在时态以及复数名词作主语时。 例如：We are friends. You are right. They are playing football. was 和 were 是be动词的过去式，分别对应is和are的过去时态。 例如：He was tired yesterday. They were at school last week. 二、常见用法 (1) 表示状态： be动词后常接形容词、名词、介词短语等，用来描述主语的状态或特征。 例如：She is happy. (状态) The book is on the desk. (位置) (2) 表示存在： 在there be句型中，be动词用于表示存在或某处有某物。 例如：There is a book on the table. (单数) There are many books in the library. (复数) (3) 进行时态中的助动词： 在现在进行时和过去进行时中，be动词（am/is/are/was/were）与动词的现在分词或过去分词一起构成进行时态，表示正在进行的动作或过去某一时刻正在进行的动作。 例如：I am reading a book. (现在进行时) They were playing games at this time yesterday. (过去进行时) (4) 被动语态： 在被动语态中，be动词是句子的助动词，后接动词的过去分词形式，表示主语是动作的承受者。例如：The book was written by him. (这本书是他写的。) (5) 疑问句和否定句： 疑问句：将be动词提前至主语前即可构成疑问句。例如：Are you a teacher? 否定句：在be动词后加not即可构成否定句。例如：She is not a singer. (6) 缩写形式： 在英语中，be动词经常与主语的人称代词和否定词缩写。 例如：I'm not sure. (I am not sure.) He isn't here. (He is not here.) They aren't students. (They are not students.) 语法实践 单项选择。 1. I ____ a student. A. am B. is C. are D. be 2. She ____ happy today. A. is B. am C. are D. be 3.
