【题目】 【1】 But still there is a danger that grows every year. Airliners get larger. Some airplanes can hold over 300 passengers. And the air itself becomes more and more crowded. If one giant airliner crashed into another in mid-air,600 lives could be lost.

【2】 Air traffic controllers tell the pilot exactly when to turn, when to climb,and when to come down. The air traffic controllers around a busy airport like London Heathrow may handle 2, 500 planes a day. Not all of them actually land at the airport. Any plane that flies near the airport comes under the orders of the controllers there. 【3】

Recently such a disaster almost happened. 【4】 One,with 69 passengers, had come from Toronto, and the other, with 176 passengers , from Chicago. An air traffic controller noticed on his radar screen that the two planes were too close to each other. He ordered one to turn to the right and to climb. But he made a mistake. He ordered the wrong plane to do this. Fifteen seconds later it flew directly in front of the second plane. They avoided each other at last. The distance between them was less than that of a large swimming pool. 【5】

A. Even a small mistake could cause a disaster.

B. Two large jets were flying towards the airport.

C. Nowadays people like traveling more by air than by car.

D. Today, air travel is far safer than driving a car on a busy motorway.

E. This is an example of the danger that grows every year.

F. In a word, air travel is more dangerous,we should choose others.

G. From the moment an airliner takes off to the moment it lands, every movement is watched on radar screens.

【题目】Researchers are placing robotic dogs (机器狗) in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people’s depression, physical activity, and life satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated (刺激),” Edwards points out. “The problem is how we promote (使……成为现实) that, especially for those without friends or help. A robotic dog could be a solution.”

In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.

“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has a mind of his own.”

The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.

“At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry, ” Beck says. “But it’s amazing how quickly we have given up that belief.”

“Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds. ”
