改否定句的方法

Answer 1

改否定句的方法：

1、首先观察句中是否含有be动词，如am, is, are, was, were，若有，则在be动词后加上not 。

2、还可以观察句中是否含有情态动词，如can, could, must, should，如果有，则在情态动词后加not 。

3、若以上两种都没有，则使用助动词+not 。助动词如do, does, did，句中的时间、人称等决定助动词的选择使用。

4、完成基础的加not后，还可能需要对句中其它词语进行更改，如some应该为any, too和also改为either， already改为yet，and改为or等。

否定句是表示否定的句子。必须有否定词，古代汉语中否定词可以是副词“不”、“弗”、“毋”、“勿”、“未”、“否”、“非”，可以是动词如“无”。
