The first two provide guidelines for solving the problem, the third serves to provide early warnings. A good programming language supports all three.In subdividing problem, some of the subproblems may be similar to the(54) problem. It leads us to a(55)solution. This(55)solution is viable provided each of the subproblems is easier to solve than the original problem.

Question 24 to 27 are based on the following passage.

Scientists can learn about man by studying animals, such as mice, rats and monkeys. The scientists in a laboratory areexperimenting on mice and they are studying the relationship between diet and health.

In this experiment, the scientists are studying the relationship between the amount of food the mice can eat and theirhealth. The mice are in three groups. All these groups are receiving the same healthy diet. But the amount of food that eachgroup is receiving is different. The first group is eating one cup of food each day, the second two cups, and the third threecups.

After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group arethinner than normal mice but they are more active. Most of the day, they are running, playing with one another, and using theequipment in their cages. Also, they are living longer. Mice usually live for two years, while most of the mice in this groupare still alive after three years.

The second group of mice is of normal weight. They are healthy, too. They are active, but not as active as the thinnermice. But they are only living about two years.

The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating orsleeping. They are not active. These mice are living longer than the scientists thought —about a year and a half, but they arenot healthy. The are sick more often than the other two groups.

听力原文： US FAMILIES TODAY

In the early days of America, the family held together for economic reasons./Father, mother and children all worked together to build the pioneer family or family business./But today, about one out of three marriages ends in divorce,/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 83% of the men who divorce remarry within 3 years./ The children from the broken families join up to produce a new kind of unit called the blended family. / About 18 million children are now living with their step-brothers and sisters in such an arrangement./

Perhaps the most significant trend today is toward the single-parent household./Of all children under 18, 17% are now living with only one parent./Business and government officials are looking for new ways/to help parents meet their family responsibilities as well as to increase their income./
