b. Read the advice below. Think how you write letters.

Are any of your ideas mentioned there?

When we write a letter about a famous sight, we can

divide it into four parts (in addition to the opening and

closing).

The first part includes the name of the place, where it

is located and what it looks like.

In the second part, we write about the history of this

place.

In the third part, we describe what visitors can see

and do there.

In the last part, we recommend a visit to this place.

Present tenses are usually used to describe this sight

and past tenses are used to write about historical facts.

The passive voice is also often used in this type of

descriptions.
