Level 3 Chapter 12 - Don't have to, don't need, needn't, mustn't
There are two logical answers to SOME questions. Tick both.
You can do this exercise two or three times: It will be different each time
Negatives of auxilliaries of obligation
"HAVE TO" and "MUST" are very similar in the affirmative but different in the negative:
MUST NOT is prohibitive. It is forbidden:
You MUST NOT walk on the grass in the park. You MUST NOT bring cocaine into the country. In conversation it is usually contracted: Johnny! You mustn't play with matches!
DON'T HAVE TO: Is permissive. There is no obligation.
I DON'T HAVE TO work on Saturday (but my boss will be delighted if I do!) You DON'T HAVE TO put milk in your tea. (Unless you are English and it is for breakfast...)
DON'T NEED TO: Is almost the same as DON'T HAVE TO It can be used in either of the two examples above.
DON'T NEED can be used with a noun and of course:
I DON'T NEED a car (I like public transport) is quite different from I DON'T HAVE a car (but I need on!)
NEEDN'T is the same as DON'T NEED TO when used with a verb: You NEEDN'T come in early tomorrow. or You DON'T NEED TO come in early tomorrow.
NEEDN'T cannot be used with a noun.
In this exercise there are some questions with two right answers. Tick them both.
