Today, I'm going to tell you the differences between must and have to.

今天，我要告訴你們must 跟 have to 之間的差異

Both must and have to talk about obligations.

must 跟 have to 兩者都涉及了義務

However!

但是！

Now, we use have to when we talk about obligations others decide for us.

當我們談論他人施予我們的責任時，我們會用have to

It's a law or a rule, so it cannot be changed.

這可能是法律或是規範，所以是不能被改變的

For example, at BBC, we have to show our passes to enter the building.

例如：在 BBC，我們必須要秀出通行證才能進入大樓

This is a rule decided by the BBC.

這是 BBC 所訂出的規則

On the other hand, we use must when we talk about obligations we decide for ourselves or others.

而當我們給自己或給他人賦予的責任，我們會用 must

For example, my boss might say to me "You must be more organized."

例如：我老闆可能對我說「你要更有條理一點」

Or, I might say to myself "I must exercise more often."

或是，我可能對自己說「我要更常運動」
