需要注意的是，"no"和"not"在具体用法中有很多复杂的规则和例外情况，上述仅是其中一部分常见的用法。

以下为两者的记忆顺口溜，供参考！

Sure! Here's a limerick to help you remember the usage of "no" and "not":

"No" is an answer of denial,

When someone asks with a trial.

"Not" negates a verb or adjective,

To express something opposite or corrective.

So when asked, reply with "no" or "not",

To show your answer, clear-cut.

Remember, "no" is for refusal or disagreement,

While "not" negates in any statement.

I hope this limerick helps you remember the usage of "no" and "not"!
