Task 1: Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.
The United States has been criticized for its treatment of its elderly citizens. Although in many other countries the elderly usually live with their children's family, many older Americans live alone, without the close companionship of their children. This situation is sometimes blamed on the "selfishness" of the young generation, but a closer look shows that many of the elderly prefer to maintain their independent lives.
Research on the situation of the elderly in America has shown that while grandparents are delighted to be visited periodically by their children and grandchildren, they prefer to continue living in the surroundings that they are familiar with. This suggests that children should permit their parents to live alone if they wish to, and should encourage them to maintain close ties to the rest of the family.
Another surprising result of the research on the elderly in the United States has been the very positive influence which pets have been found to have on the elderly people that they live with. It has been shown that elderly people who care for small pets, such as cats and dogs, live longer, are healthier, and have better attitudes towards their lives than similar elderly people without these companions.
1. Many elderly Americans live ____.
A. without satisfaction. B. by themselves.
C. a lonely life. D. a simple life.
2. What do some people see as the cause of this situation?
A. The society of the USA treats its elderly people as troubles.
B. The young people usually trouble the elderly of their own.
C. The government concerns hardly about the elderly people.
D. The young people are too selfish.
3. Many of the elderly Americans want to ____.
A. keep living in their well-known places and conditions.
B. remain with the grandchildren in their houses.
C. remove to their sons' or daughters' homes.
D. live with their friends in their hometown.
4. The author advises the young people to ____.
A. keep close ties with the elderly of their own.
B. let the elderly of their families live by themselves.
C. permit their elderly relatives to raise some pets.
D. respect the wishes of their elderly parents.

A. the elderly who care for some pets live together.
B. the social practice in the USA makes the elderly live alone.
C. the elderly people should have better attitudes towards their lives.
