Unlike Britain, the US does not have a national health care service. Most people buy medical insurance to help pay for medical care. The government only helps pay for some medical care for the old and the people who are on low incomes. The problems of those who cannot afford insurance have become an important political subject.
In Britain, when people are ill, they usually go to a family doctor first. However, people in America sometimes go straight to an expert. Children are usually taken to a doctor who is an expert in the treatment of children. In Britain, if a patient needs to see a specialist doctor, their family doctor will usually recommend a specialist, which will save more time and money both for the patients and the public fund(基金).
In Britain, doctors do not go to people’s homes when they are ill. People always make appointments to see the doctor in the doctor’s office. In a serious situation, people call for an ambulance. In America, hospitals must treat all seriously ill patients, even if they do not have medical insurance. The gov-ernment will then help pay for some of the cost of the medical care.

解析
The African elephant, the largest land animal remaining on the earth, is of great importance to African ecosystem(生态系统). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna(大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas(热带草原). In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.
