Do We Have To?
On Sunday, Mac and Rory visit the National Gallery with their friend, Adam.
We use must or have to to describe something that is necessary.

​
You must not does not mean the same as you don't have to.
​
Must not means it is necessary not to do something. Here, Mac is not allowed to touch the exhibit.
​
If the security man said, "you don't have to touch the exhibits" it would mean it is not necessary to touch the exhibits, but you can if you want to!
​
An hour later...
"We don't have to see any more" means it's not necessary to see any more paintings.
​
Now it's your turn!
What things do you have to do? Perhaps you have to do your homework, help your parents or tidy your bedroom?
​

​
A few minutes later, in a park across the road, on top of a statue of a giant...
