2. must/have to
[一语击破]
A.两者都可以表示“必须”。must 着重表示主观上认为有义务有必要。have to 着重于表示客观上的需要，含有“不得不”的意味。例如：
We must work hard. 我们必须卖力工作。（是我们要这样做）
We have to work hard. 我们得卖力干活。
（环境使我们不得不这样做）
B.must 只有一种形式，并且无人称、时态和数的变化。而have to要随主语人称、时态和数的变化而变化。例如：
I’ll have to go with her tomorrow. 明天我得同她一道去。
When I was your age, I already had to work.
我像你这么大时，早已不得不工作了。
He has to stay at home because he is ill.
因为病了他不得不呆在家中。
C.must和have to 的否定式表示的意义不同：must not 表示“不应该、不许可、禁止、千万别”等意思；not have to 表示“不必”，与needn’t 同义。例如：
You must not smoke in the classroom. 不准在教室里抽烟。
You don’t have to worry about his studies.
你不必为他的学习而担心。
You mustn’t tell him about it. 你一定不要把这件事告诉他。
You don’t have to tell him about it. 你不必把这件事告诉他。
