3a
What about these
They also don’t need to change forms. They follow modal verbs(情態(tài)動(dòng)詞).
Presentation
情態(tài)動(dòng)詞三原則：
● 情態(tài)動(dòng)詞不能單獨(dú)使用，后面需加動(dòng)詞原形。
● 情態(tài)動(dòng)詞沒有人稱和數(shù)的變化(have to除外)。
● 情態(tài)動(dòng)詞否定直接在后面加not (have to除外，
have to的否定形式是not have to)。
Presentation

Presentation
情態(tài)動(dòng)詞must與have to：
have to表示“必須”時(shí)，與must意義很接近，有時(shí)可與must互換。例如：
We have to/ must follow the rules.
但是它們也有所不同。
Presentation
must和have to的不同：
1. We must hurry. I don’t want to miss the
beginning of the show.
We have to hurry. The train is leaving
in five minutes.
must 通常表示的是說話人的主觀看法，語(yǔ)氣比較強(qiáng)烈；
have to往往強(qiáng)調(diào)客觀需要。
Presentation
must和have to的不同：
2. You mustn’t talk to your mother like that.
You don’t have to come if you don’t want to.
它們的否定式含義大不相同。mustn’t表示“不準(zhǔn)、禁止”，而don’t have to 表示“不必”。

3. I/We/You/They/He must do something about it.
I have to finish my work today.
