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"!
