【語(yǔ)法知識(shí)聚焦】
1. have to 與情態(tài)動(dòng)詞的區(qū)別
情態(tài)動(dòng)詞不能單獨(dú)作謂語(yǔ)，后面必須接動(dòng)詞原形一起構(gòu)成謂語(yǔ)，have to 也是這樣。
情態(tài)動(dòng)詞沒(méi)有人稱和數(shù)的變化，而且所用的時(shí)態(tài)也受到一定的限制，但是have to 有人稱和數(shù)的變化，可用于多種時(shí)態(tài)中，在一般現(xiàn)在時(shí)中，當(dāng)主語(yǔ)是第三人稱單數(shù)時(shí)，要用has to, 其余人稱用have to；一般過(guò)去時(shí)中用had to；一般將來(lái)時(shí)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(xué)。
If you get ill, you'll have to see the doctor.
如果你生病的話，你就得看醫(yī)生。
2. have to 與must 的區(qū)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(qū)別：
have to 強(qiáng)調(diào)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(shì)逼迫”的意味；must 強(qiáng)調(diào)說(shuō)話者主觀上認(rèn)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(xué)的路上壞了，我不得不走路去上學(xué)。
�。ㄎ冶緛�(lái)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(xué)好英語(yǔ)。（主觀上有這種想法。）
(2) 否定式的區(qū)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(kāi)頭的一般疑問(wèn)句的肯定回答為“Yes, 主語(yǔ)+must”，否定回答為“No, 主語(yǔ)+needn't / don't have to”。例如：
---Must I finish the homework now? 我必須現(xiàn)在完成作業(yè)嗎？
---Yes, you must. (No, you needn't / don't have to) 是的，你必須現(xiàn)在完成。（不，你不必。）
3. 反意疑問(wèn)句的構(gòu)成區(qū)別：
(1) 陳述部分含有have to 時(shí)，其附加問(wèn)句的謂語(yǔ)往往用助動(dòng)詞do的相應(yīng)形式或助動(dòng)詞will。例如：
You had to go shopping yesterday, didn't you?
昨天你不得不去購(gòu)物，是嗎？
(2) 陳述部分含有must 時(shí)，其附加問(wèn)句的謂語(yǔ)，按下面幾種情況來(lái)確定：
A. must 意為“必須”時(shí)，附加問(wèn)句謂語(yǔ)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(wèn)句謂語(yǔ)用must。例如：
The boy mustn't play with the knife, must he?
那個(gè)男孩不能玩刀子，對(duì)嗎？
C. must 意為“應(yīng)該”時(shí)，附加問(wèn)句謂語(yǔ)用mustn't。例如：
We must help each other, mustn't we? 我們應(yīng)該互相幫助，對(duì)嗎？
D. must 意為“一定；想必”表示推測(cè)時(shí)，附加問(wèn)句部分謂語(yǔ)要根據(jù)must后面的動(dòng)詞來(lái) 確定。例如：
Mr Wang must be at home, isn't he? 王先生一定在家，對(duì)嗎？
注：
must 表示的是一種相當(dāng)肯定的與事實(shí)非常接近的推測(cè)。例如：
Mr Wang must be at home. 其實(shí)就相當(dāng)于Mr Wang is at home.
因此，它的反意疑問(wèn)句的附加問(wèn)句部分是isn't he 也就很容易理解了。
又如：They must be right, aren't they?
