文字稿

Hi, this is Kee from BBC Learning English. Today, I’m going to tell you the differences between must and have to.

Both must and have to talk about obligations. However!

Now, we use have to when we talk about obligations others decide for us. It’s a law or a rule, so it cannot be changed. For example: At BBC, we have to show our passes to enter the building. This is a rule decided by the BBC.

On the other hand, we use must when we talk about obligations we decide for ourselves or others. For example, my boss might say to me: You must be more organised. Or, I might say to myself: I must exercise more often.

用法總結

Must and have to

Both must and have to talk about obligations. Both are followed by an infinitive without ‘to’.
兩者都用來描述 「義務」,而且兩者後面都直接跟動詞原形,即 「must do something」 和 「have to do something」。

1. Have to
Have to‘ is used for obligations that others decide for us. These are often laws or rules and so cannot be changed.
「Have to」 用來談論 「客觀要求」。這些通常是法律或規定,因此不能改變。

  • We have to show our passes to enter the building.
  • You have to smoke outside. Smoking is not allowed inside.
  • She has to have a license before she drives.

2. Must
We use must to talk about obligations we decide for ourselves or others.
我們用 「must」 來談論「主觀義務」,指對自己或他人的要求。

  • You must be more organised.
  • I must exercise more often.
  • We must clean the house today.
