否定句的转变规则

否定句的转变有两种常见的情况，一种是含有be动词（am、is、are）和情态动词（can、could、may、must、shoud、will、would等）的情况，另一种是没有这些动词的情况。

一、含有be动词和情态动词的句子

对于含有be动词或情态动词的句子，我们只需在这些动词后加上not。例如：

“I am a student.”变为“I am not a student.”

“Amy is a good girl.”变为“Amy is not a good girl.”

“These flowers are very beautiful.”变为“These flowers are not very beautiful.”

“I can swim.”变为“I cannot swim.”

二、没有be动词和情态动词的句子

对于没有be动词或情态动词的句子，我们需要在动词前加上助动词，并恢复为动词的原形。例如：

“I like math.”变为“I don’t like math.”

“Jack likes math, too.”变为“Jack doesn’t like math, either.”

“They like bananas and apples.”变为“They don’t like bananas or apples.”

“Lily gets up at six every morning.”变为“Lily doesn’t get up at six every morning.”

“His father likes playing football.”变为“His father doesn’t like playing football.”

“I went fishing yesterday.”变为“I didn’t go fishing yesterday.”
