The Northern Pike is a very bad fish. It is a big, hungry fish, and eats little fish. Many Northern Pike live in Lake Davis. They are killing all the smaller fish in the lake. The Northern Pike area serious danger to the lake because they eat all the smaller fish. Soon, all other kinds of fish in the lake will be killed off. This is not healthy for the environment (环境).

Researchers are afraid that the Northern Pike will swim out of Lake Davis through many smaller rivers that feed into the lake. They could spread all over the country and damage many other water environments. If that happens, it would be too late to stop the Northern Pike.

For ten years, officials have been trying to remove the Northern Pike from Lake Davis. They have tried using nets and poisons (毒). However, the Northern Pike population is still doing well in Lake Davis. Many people do not like the idea of using poison to kill the fish. They worry that the poisons are bad for humans who use the water. However, people haven’t found any poisons at all in local (当地的) wells.

Scientists are going to try the poison again. This time, they will dry off the lake before putting the poison in. A public hearing will be held to talk about the problem.

Samuel H. Preston, a sociologist at the University of Pennsylvania, studied how the American family is changing. He reported that by the time the average American couple reaches 40 years of age, they have more parents than children. This finding shows the change in lifestyles (生活方式) and duties of aging Americans. The average middle-aged couple can look forward to caring for elderly parents some time after their own children have grown up.

Because Americans are living longer than ever, more researchers and social workers have begun to study care giving to improve care of the elderly. When people care for an elderly relative, they often do not use community (社区) services, such as adult (成人) daycare centres. If the care givers are adult children, they are more likely to use such services, especially because they often have jobs and other business. However, the wife of an elderly person is much less likely to use support services or to put the dependent person in a nursing home. Social workers discovered that the reason for this difference was fear of becoming poor. An ill elderly person may live for years, and medical care and nursing homes are very expensive. An elderly couple’s savings can disappear very quickly. The other half, usually the wife, can be left in poor living conditions. As a result, she often tries to take care of her husband herself for as long as she can.
