英语否定句怎么改

要将一个陈述句改成否定句，你只需要在谓语动词前加上否定副词“not”，或者使用缩略形式如“don't”，“doesn't”，“didn't”等。下面我将举几个例子来说明如何把不同的句子改成否定句。

1. 一般现在时

陈述句：

- I like ice cream.

- She plays the piano every day.

否定句：

- I do not like ice cream. (或 I don't like ice cream.)

- She does not play the piano every day. (或 She doesn't play the piano every day.)

2. 一般过去时

陈述句：

- He visited his grandmother last week.

- They played soccer yesterday.

否定句：

- He did not visit his grandmother last week. (或 He didn't visit his grandmother last week.)

- They did not play soccer yesterday. (或 They didn't play soccer yesterday.)

3. 一般将来时

陈述句：

- We will go to the park tomorrow.

- She will read a book tonight.

否定句：

- We will not go to the park tomorrow. (或 We won't go to the park tomorrow.)

- She will not read a book tonight. (或 She won't read a book tonight.)

4. 现在进行时

陈述句：

- She is reading a book.

- They are playing basketball.

否定句：

- She is not reading a book. (或 She isn't reading a book.)

- They are not playing basketball. (或 They aren't playing basketball.)

通过以上例子可以看出，将陈述句转换为否定句的关键在于正确地添加否定副词，并根据时态选择合适的助动词。希望这些例子对你有所帮助！
