Families and cars
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 (大蓬
货车).
A small car can hold four persons and a large car can hold six persons but it is very crowded. A
van can 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.
Its sixth and seventh seats are used to put other things, for a family of five must carry many things when
they travel. When they arrive at their grandparents' home, the things are brought into the two seats, and
then it can 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.
