人教版三年级英语肯定句转换否定句练习题50题含答案解析
人教版三年级英语肯定句转换否定句练习题50题含答案解析1. She is a girl. Which is the correct negative form?A. She no is a girlB. She is not a girlC. She not is a girlD. She don't is a girl答案：B解析：在将肯定句转换为否定句时，有be动词（am/is/are）的句子，直接在be动词后加not。
原句中的be动词是is，所以否定形式为She is not a girl。
2. I am happy. How do we make it negative?A. I amn't happyB. I no am happyC. I'm not happyD. I don't am happy答案：C解析：I am的否定形式可以缩写为I'm not。
A选项amn't这种形式是错误的；B选项no不能这样直接加在am前；D选项有be动词的句子不需要用助动词don't。
3. He is my father. What is the negative sentence?A. He is no my fatherB. He not is my fatherC. He isn't my father答案：C解析：对于有be动词is的肯定句，变为否定句就在is后加not，is not可缩写为isn't。
4. It is a cat. Which one is the negative form?A. It is no a catB. It not is a catC. It isn't a catD. It don't is a cat答案：C解析：这里的肯定句有be动词is，转换为否定句就是在is后面加not，缩写为isn't。
