【语法知识聚焦】
1. have to 与情态动词的区别
情态动词不能单独作谓语，后面必须接动词原形一起构成谓语，have to 也是这样。
情态动词没有人称和数的变化，而且所用的时态也受到一定的限制，但是have to 有人称和数的变化，可用于多种时态中，在一般现在时中，当主语是第三人称单数时，要用has to, 其余人称用have to；一般过去时中用had to；一般将来时中用will have to, 例如：
She has to go to school by bus.
她不得不乘公共汽车去上学。
If you get ill, you'll have to see the doctor.
如果你生病的话，你就得看医生。
2. have to 与must 的区别
have to 和must 都有“必须”的意思，那么它们 有哪些不同呢？
(1) 含义和用法上的区别：
have to 强调客观上需要做某事，即表示外界条件的需要不得不做某事，含有“形势逼迫”的意味；must 强调说话者主观上认为必须做某事，含有“主观判断”的意味， 例如：
My bike was broken on my way to school. I had to walk there.
我的自行车在上学的路上坏了，我不得不走路去上学。
（我本来不愿意走路，可是自行车坏了，不想走路也不行。）
We must learn English well.
我们必须学好英语。（主观上有这种想法。）
(2) 否定式的区别：
have to 的否定式意为“不必”，must的否定式意为“禁止；不允许”。因此，以must开头的一般疑问句的肯定回答为“Yes, 主语+must”，否定回答为“No, 主语+needn't / don't have to”。例如：
---Must I finish the homework now? 我必须现在完成作业吗？
---Yes, you must. (No, you needn't / don't have to) 是的，你必须现在完成。（不，你不必。）
3. 反意疑问句的构成区别：
(1) 陈述部分含有have to 时，其附加问句的谓语往往用助动词do的相应形式或助动词will。例如：
You had to go shopping yesterday, didn't you?
昨天你不得不去购物，是吗？
(2) 陈述部分含有must 时，其附加问句的谓语，按下面几种情况来确定：
A. must 意为“必须”时，附加问句谓语用needn't。例如：
We must clean the room, needn't we? 我们必须打扫房间，是吗？
B. mustn't意为“禁止”之意，附加问句谓语用must。例如：
The boy mustn't play with the knife, must he?
那个男孩不能玩刀子，对吗？
C. must 意为“应该”时，附加问句谓语用mustn't。例如：
We must help each other, mustn't we? 我们应该互相帮助，对吗？
D. must 意为“一定；想必”表示推测时，附加问句部分谓语要根据must后面的动词来 确定。例如：
Mr Wang must be at home, isn't he? 王先生一定在家，对吗？
注：
must 表示的是一种相当肯定的与事实非常接近的推测。例如：
Mr Wang must be at home. 其实就相当于Mr Wang is at home.
因此，它的反意疑问句的附加问句部分是isn't he 也就很容易理解了。
又如：They must be right, aren't they?
