    Where do you like to live? For this question, different people have different answers. Some people like to live in a city because there are many shops and supermarkets. They think it is convenient（方便的） to buy things. But some people think it is good to live in a quiet town because they don't like the dirty air in the big city. They dislike pollution（污染） in the city.

    Today, some people like travelling, so they would like to buy caravans. A caravan is both a house and a car. You can't buy it unless（除非）you have enough money. There is a driving area in the car. You can do lots of things in the car. There is a bed and a lamp in the bedroom. You can make dinner in the kitchen. You can also find a fridge and a sink（水池） inside. You can listen to music and watch TV in the sitting room. If you are tired, you can have a shower（淋浴） or a bath in the bathroom. You can do most things you want to do.   

Life is travelling. Do you want to live in this kind of car?
