Let's look at the sentence pattern.

This pattern is the structure that all of our examples will follow.

Noun plus must plus bear infinitive.

In this pattern, we start with a noun, the person or thing, we're strongly advising.

We follow it with the modal verb must, which clearly shows the suggestion

is strong and important. Finally, we use a verb in the bare infinitive form, expressing the recommended

action clearly and directly. When we say must, we're expressing a very strong recommendation or necessity.

Notice that must never changes form and is always followed by the base form of the verb.

Let's see how a line from the dialogue follows this pattern.

You must take your family out to the country sometime. In this sentence, you is the noun.

It's the person who is receiving the suggestion.

Must indicates that the speaker feels strongly about the suggestion,

and take is the verb in its infinitive form,

showing the action the speaker recommends.

The speaker strongly suggests the listener do something enjoyable, take their family to the

countryside.

This sentence pattern can also be used when making an invitation to someone.

When saying something like, you must come to our party on Saturday, the invitation is, in a way,

a strong suggestion. Note that must usually has the feeling of a formal suggestion. It can

also be used to give strong recommendations for serious topics, like when giving advice about health.

Now, let's look at some speaking examples.

London is really fantastic and you must go there.
