We looked at how to use must a couple
of months ago. Must used like that shows necessity. (You
must study hard if you want to pass the test.)
See that lesson
Now we will look at another way to use must. This is when you
think something is true based on a logical conclusion (or what you
think is true.)
For example: You hear something on the roof that sounds like
raindrops. You say It must be raining. (You can guess
it's raining because you hear the raindrops.)
Or: Your co-worker goes to the swimming pool everyday. You
think he probably likes to swim. You might say He must like
to swim.
Or: A boy eats everything on his plate except the beans. You
might think He must not like beans.
So remember, must comes before the verb. If it is a negative
sentence, use must not before the verb.

Make a sentence using must as a
conclusion. The first one is done for you.
