Americans with small families own a small car or a large one. If both parents are working, they usually have two cars. When the family is large, one of the cars is sold and they will buy a van(住房汽车).

A small car can hold(容纳)four persons and a large car can hold six persons, but it is very crowded(拥挤). A van hold seven persons easily, so a family with three children could ask their grandparents to go on a holiday travel. They could all travel together.

Mr.Hagen and his wife had a third child last year. This made them sell a second car and buy a van. Their children sixth and seventh seats are used to put other things, for a family of five must carry many suitcases(衣箱)when they travel. When they arrive at their grandparents’ home , the suitcases are brought into the two seats, the van can then carry the grandparents.

Americans call vans motor homes. A motor home is always used for holidays. When a family are traveling to the mountains or to the seaside, they can live in their motor home for a few days or weeks. All the members of a big family can enjoy a happier life when they are traveling together. That is why motor homes have become very popular. In America there are many parks for motor homes.
