When the floor is dirty,my brother is always the first one to（）it.

When Mrs. Joseph Groger died recently in Vienna, Austria, people asked, "Why did she live to be 107？" Answers were provided by an investigation made among 148 Viennese 一 men and women who had reached the age of 100. Somewhat surprising was the fact that the majority had lived most their lives in cities. In spite of the city's image as an unhealthy place, city living often provides benefits that country living may lack. One factor seems to be important to these long-lived persons.
This factor is exercise. In the cities, it is often faster and less frustrating to walk short distances than to wait for a bus. Even taking public transportation often requires some walking. Smaller apartment houses have no elevators, and so tenants must climb stairs. City dwellers(居民) can usually walk to local supermarkets. Since parking spaces are hard to find, there is often no alternative to walking.
On the other hand, those who live in the country and suburbs do not have to walk every day. In fact the opposite is often true. To go to school, work or almost anywhere else, they must ride in cars.

There was once a man in South America who had a parrot(鹦鹉), a pet bird that could imitate(模拟) human speech. The parrot was unique. There was no other bird like him in the whole world. He could learn to say any word except one. He could not say the name of his native town, Cotano. The man did everything he could to teach the parrot to say “Cotano” but he never succeeded. At first he was very gentle with the bird, but gradually he lost his temper. “You stupid bird! Why can't you learn to say that One word! Say 'Cotano' or I'll kill you!” But the parrot would not say it. Many times the man screamed(大声叫), “Say 'Cotano' or I'll kill you!” But the bird would never repeat the name. Finally the man gave up. He picked up the parrot and threw him into the chicken house. “You are even more stupid than the chickens!”
In the chicken house, there were four old chickens waiting to be killed for Sunday's dinner. The next morning, when he went out to the chicken house, the man opened the door. He was shocked by what he saw. He could not believe his eyes and ears. On the floor lay three dead chickens, the parrot was screaming at the fourth, “Say 'Cotano' or I'll kill you!”
