练习题：be动词的变化与一般疑问句、否定句一、be动词的变化be动词是英语中最常用的动词之一，用于表示存在、状态、身份等。

be动词的变化包括以下几个形式：am、is、are、was、were。

1. 第一人称单数形式：am- 例如：I am a student.2. 第三人称单数形式：is- 例如：He is a teacher.- 例如：She is a doctor.3. 第一人称复数形式：are- 例如：We are students.4. 第三人称复数形式：are- 例如：They are doctors.5. 过去时第一、三人称单数形式：was- 例如：He was here yesterday.- 例如：She was tired last night.6. 过去时第一、三人称复数形式：were- 例如：We were at the party yesterday.- 例如：They were happy to see each other.二、一般疑问句的构成与回答一般疑问句是用于询问陈述句的真假或事实的句型。

构成一般疑问句的方法是将be动词放在句首，紧接主语，然后用问号结尾。

例如：- Are you a student?（你是学生吗？）- Is he a teacher?（他是老师吗？）对于一般疑问句的回答可以采用以下几种方式：1. 肯定回答：Yes, 主语 + be动词。

- 例如：Yes, I am.（是的，我是。

）- 例如：Yes, he is.（是的，他是。

）2. 否定回答：No, 主语 + be动词 + not。

- 例如：No, I am not.（不，我不是。

）- 例如：No, he is not.（不，他不是。

）三、否定句的构成否定句用于表示否定的陈述或命令，使用be动词的否定形式。

构成否定句的方式是在be动词后加not。

例如：- I am not a student.（我不是学生。
