When do we use have to / must / should + verb ?


  • to talk about obligation, things that are necessary to do, or to give advice about things that are a good idea to do.

  • Must and have to are both used for obligation and are often quite similar. They are both followed by the infinitive 
I must go now. / I have to go now.
Are these exactly the same?
base verb - without "to"
Example: to talk, to walk are the verb but when we say " walk,/ talk"  this is known as the infinitive. 

Slide 5 - Tekstslide

Well, almost......
We often use must for more personal opinions about what it is necessary to do, and have to for what somebody in authority has said it is necessary to do.

Have to shows us that the obligation comes from somebody else. It’s a law or a rule and the speaker can’t change it.
Do you have to wear a uniform at your school?
John can’t come because he has to work tomorrow.
In Britain you have to buy a TV licence every year.
Obligation: Something that you need to do

Slide 6 - Tekstslide

Must shows us that the obligation comes from the speaker. It isn’t a law or a rule. 


I must call my dad tonight.
You must hand in your homework on Tuesday or your mark will be zero.
You must come and visit us the next time you come to London.

Slide 7 - Tekstslide

Have to is more frequent in conversation; must is used more in formal writing, for example in written notices.

Slide 8 - Tekstslide

No obligation
We use don’t have to to show that there is no obligation. You can do something if you want to but it’s not compulsory.

It’ll be nice if you do but you don’t have to come with me if you don’t want to.
You don’t have to dress up for the party. Wear whatever you feel comfortable in.

Slide 9 - Tekstslide

Finally....
There’s something very important about must and have to. The positive forms are very similar in meaning, but the negative forms are completely different.

You mustn’t forget ...(don’t forget - you have no choice)
If you don't like him, you don't have to see him again. (there is no obligation to see him again, but you have a choice) (NOT You haven't to see him again)
