在這一課里, 我們要學(xué)習(xí)的是助動(dòng)詞should跟 must的用法. 我們也要看看這兩個(gè)助動(dòng)詞的否定式 should not也就是 shouldn't 和 must not 也就是 mustn't 在意思上跟 don't have to這個(gè)詞組有什么分別. 首先我還是請(qǐng)兩位英文老師給你念一段對(duì)話, 請(qǐng)你注意聽英文老師的發(fā)音和聲調(diào).
對(duì)話原文
F: Peter, can you help me for a minute?
M: Yes, what do you want me to do?
F: Will you take the garbage out?
M: Do I have to do it now?
F: Well, you don't have to it now. But don't forget to do it today.
M: All right. I really must go now; otherwise I'll be late for school.
F: You have an exam this morning, don't you? You mustn't be late. Maybe you should ask your father for a ride.
