单选题We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded. When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(迁移)is probably the migration of fish, which is called"salmon". This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birth- place in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea. Recently, scientists have studied the migration of kind of lobster (龙虾). Every year, when the season of bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don't. Maybe living things just like to travel.

单选题{{B}}D{{/B}} Is the American family in trouble? Today, about one out of three marriages end in divorce (离婚), and more and more of them involve children. The divorce rate in America is still the highest in the world, but 75% of the women and 85% of the men who divorce remarry with in three years. About 18 million children are living with their step brothers and sisters. One of the biggest problems facing families today is the rising cost of raising a child. Experts say that at today's prices, a family of four, earning $ 20 000 a year, should expect to spend over $ 55 000 to sup port a child to the age of 18 and this does not include the money for college education. Many women are supporting the family by going back to work. Today, one-half of all married women with school-age children have some kinds of job outside the home. Most mothers work because they need money. As a result, an American child usually spend most weekends with day-care workers or teachers and other children and not with his or her family. Economic conditions kept the early families of America together, and now in modern society, economic conditions are the reason for their moving apart.
