2. See Explanation
MORE MODALS (and SEMI-MODALS): MUST
USE:
Used to talk about a strong necessity, obligation, or duty to do something.
There is often very little difference between MUST and HAVE TO. In formal,
written English, MUST is used for public notices about official rules and
regulations. MUST can also be used to express a strong opinion about a
situation based on existing facts or circumstances.
AFFIRMATIVE
FORM:
[SUBJECT + MUST + VERB...]
EXAMPLES:
"I have a terrible toothache; I must go to the dentist."
"We must try to help Nicky; she's our oldest friend."
"All workers must wear safety helmets in work areas!"
"Jack must be on his way. There was no one home when I called his
apartment."
NEGATIVE
USE:
In both formal and informal English we use the negative form MUST NOT (often
shortened to MUSTN'T) to talk about something which is wrong or forbidden.
Note that this is not the same as the negative form of HAVE TO, which only
means that something is not necessary.
FORM:
[SUBJECT + MUST + NOT (MUSTN'T) + VERB...]
EXAMPLES:
"You mustn't pull the dog's tail, dear; he'll bite you."
"We mustn't forget to pay back that loan."
"Workers must not smoke in work areas!"
QUESTIONS AND ANSWERS
USE:
Used to ask whether something is necessary or obligatory. The interrogative
form of HAVE TO has the same meaning and is more common.
