The doctor's advice
In this session, we're going to look at must and have to in more detail. First, read this summary of what the doctor said to Mr Christmas (hear Mr Christmas talk about his meeting with his doctor in activity 2, session 1):
"Andy, your diet is not very healthy. The good news is you don't have to stop celebrating Christmas every day. You must stop eating so much. You mustn't eat all that fatty food. And remember, you have to take some exercise."

本课语法
If you must do something, it is necessary for you to do it, but this is often your opinion or a rule that you have made yourself.
If you have todo something, it is necessary for you to do it. It’s a law, an obligation or a fact.
If you don’t have to do something, it isn’t necessary to do it, but you can if you want.
If you mustn’t do something, it means ‘don’t do it’. It is necessary not to do it.
