【語法知識聚焦】
1. have to 與情態動詞的區別
情態動詞不能單獨作謂語，后面必須接動詞原形一起構成謂語，have to 也是這樣。
情態動詞沒有人稱和數的變化，而且所用的時態也受到一定的限制，但是have to 有人稱和數的變化，可用于多種時態中，在一般現在時中，當主語是第三人稱單數時，要用has to, 其余人稱用have to；一般過去時中用had to；一般將來時中用will have to, 例如：
She has to go to school by bus.
她不得不乘公共汽車去上學。
If you get ill, you'll have to see the doctor.
如果你生病的話，你就得看醫生。
2. have to 與must 的區別
have to 和must 都有“必須”的意思，那么它們 有哪些不同呢？
(1) 含義和用法上的區別：
have to 強調客觀上需要做某事，即表示外界條件的需要不得不做某事，含有“形勢逼迫”的意味；must 強調說話者主觀上認為必須做某事，含有“主觀判斷”的意味， 例如：
My bike was broken on my way to school. I had to walk there.
我的自行車在上學的路上壞了，我不得不走路去上學。
（我本來不愿意走路，可是自行車壞了，不想走路也不行。）
We must learn English well.
我們必須學好英語。（主觀上有這種想法。）
(2) 否定式的區別：
have to 的否定式意為“不必”，must的否定式意為“禁止；不允許”。因此，以must開頭的一般疑問句的肯定回答為“Yes, 主語+must”，否定回答為“No, 主語+needn't / don't have to”。例如：
---Must I finish the homework now? 我必須現在完成作業嗎？
---Yes, you must. (No, you needn't / don't have to) 是的，你必須現在完成。（不，你不必。）
3. 反意疑問句的構成區別：
(1) 陳述部分含有have to 時，其附加問句的謂語往往用助動詞do的相應形式或助動詞will。例如：
You had to go shopping yesterday, didn't you?
昨天你不得不去購物，是嗎？
(2) 陳述部分含有must 時，其附加問句的謂語，按下面幾種情況來確定：
A. must 意為“必須”時，附加問句謂語用needn't。例如：
We must clean the room, needn't we? 我們必須打掃房間，是嗎？
B. mustn't意為“禁止”之意，附加問句謂語用must。例如：
The boy mustn't play with the knife, must he?
那個男孩不能玩刀子，對嗎？
C. must 意為“應該”時，附加問句謂語用mustn't。例如：
We must help each other, mustn't we? 我們應該互相幫助，對嗎？
D. must 意為“一定；想必”表示推測時，附加問句部分謂語要根據must后面的動詞來 確定。例如：
Mr Wang must be at home, isn't he? 王先生一定在家，對嗎？
注：
must 表示的是一種相當肯定的與事實非常接近的推測。例如：
Mr Wang must be at home. 其實就相當于Mr Wang is at home.
因此，它的反意疑問句的附加問句部分是isn't he 也就很容易理解了。
又如：They must be right, aren't they?
