This week we received a question from Candy in China. Candy writes,I wonder what is the difference between "not" and "no"?Today when I do my homework, I encounter the question.I do not know if it is "no need to do something" or "not need to do something" - Candy, ChinaDear Candy, thank you for writing to us.We do not usually answer homework questions, but I will try to explain the difference between the two expressions.The word "not" is an adverb, which means it modifies -- or changes the meaning of -- a verb."Not" is often used with modal verbs, like "should," "can" and "might."Here are two examples.You should not go to the park today.We might not have time to go before dark.The phrase you saw, "not need to do something," looks like it is part of a sentence where "need" is used as a verb.Here are some examples.You do not need to clean the room.I have not walked the dog today.They are not working on the project.In those sentences, "not" modifies the verbs clean, walk, and work.They show how "not" can be used as an adverb.
本周，我们收到了中国的Candy的来信。Candy写道：我想知道not和no之间有什么区别？今天我在写作业的时候遇到了这个问题。我不知道应该是“no need to do something”还是“not need to do something”。―来自中国的Candy。亲爱的Candy，感谢你的来信。我们通常不回答作业上的问题，但是我将会尝试解释这两句短语之间的差异。Not这个单词是副词，表示它修饰或改变动词的含义。Not通常与情态动词配合使用，例如should、can和might。以下是两个例子：你今天不应该去公园。我们天黑前可能没时间去。你看到的短语“not need to do something”看起来是need用作动词的句子的一部分。以下是一些例子：你没必要打扫房间。我今天还没有遛狗。他们没在做这个项目。在这些句子中，not修饰clean、walk和work这些动词。它们展示了not如何被用做副词。
