Q:
A friend of yours is going on holiday soon and has asked you to recommend a destination.

Write a letter to your friend and recommend a good place for a holiday that you have visited before. Say where you went, where you stayed, what you can do there and what the food was like.

Dear Kenny,

I haven't seen you for ages. How are you? Since my colleague asked me for helping him to buy some books talk about local tours yesterday, it made me remember that you asked me to recommend you a place to spend your coming holiday at the telephone conversation last week.

In case I have to find a place to spend my holiday soon, I will go to Taiwan. Not only because Taiwan is abundant in food which have a reasonable price, but also you can find many different kind of books you like. You should go to Taipei since there is the capital of Taiwan if you have never been there before. Hotels are easy to be found, restaurants in downtown are pretty good, and the museum are worth to visit also.

Whish you have a nice journey.

Cheers
Assman
