　　An underwater robot (机器人) that can hear the calls of whales, and so help ships to avoid them, has just been successfully tested in the Bahamas.

　　The scheme （方案） relies on a fish-shaped glider (滑翔机) that moves freely through the ocean. It can dive down as far as 200 meters below the surface and direct itself by shifting a weight from fore to aft. A microphone attached to the bottom of the glider can pick up calls from all whales, including the high frequency call of the beaked whale, which until now has been difficult to detect. The glider returns periodically to the surface to radio its data back to base, or if that’s too far away, it can call a satellite phone and send its information anywhere in the world.

　　“We are entering a new era of underwater sensing,” says Jim Theriault of Defence Research and Development Canada, Dartmouth, who ran the test. “We can put a glider in the Bahamas and control it in Nova Scotia.”

　　The hope is that naval or other ocean-going operations that use sonar (声纳) will be able to move easily to track where whales are, and so avoid using their noisy equipment when they are close by. There is circumstantial evidence (旁证) that sonar can upset whales and a number of strandings  (搁浅) have been seen shortly after naval sonar operations. “We’re trying to lower the potential risk by knowing the animals are there,” says Theriault.

　　A. a man   B. a fish

　　C. a snake   D. a turtle

　　45. The underwater robot is built to           .

　　A. help whales move to the Bahamas

　　A. dive down as far as 200 meters below the surface

　　B. stay deep in the water

　　C. call a satellite phone

　　D. come to the surface periodically

　　47. The best title for the passage would be “          ”.

　　A. Whales are in dangerB. Whales are difficult to find

　　C. Robot built to kill whalesD. Robot built to spy on whales

　　Mark was walking home from school one day when he noticed that the boy ahead of him had tripped and dropped all the books he was carrying, along with two sweaters, a baseball bat, a glove and a small tape recorder. Mark knelt down and helped the boy pick up the scattered articles. Since they were going the same way, he helped to carry part of the burden. As they walked, Mark discovered the boy’s name was Bill, that he loved video games, baseball and history, that he was having a lot of trouble with his other subjects and that he had just broken up with his girlfriend.

　　Mark went home after leaving Bill at his house. They continued to see each other around school, had lunch together once or twice, and then both graduated from junior high school. They ended up in the same high school, where they had brief contacts over the years. Finally the long-awaited senior year came. Three weeks before graduation, Bill asked Mark if they could talk.

　　Bill reminded him of the day years ago when they had first met. “Do you ever wonder why I was carrying so many things home that day?” asked Bill. “You see, I cleaned out my locker because I didn’t want to leave a mess for anyone else. I had stored away some of my mother’s sleeping pills and I was going home to commit suicide. But after we spent some time together talking and laughing, I realized that if I had killed myself, I would have missed that time and so many others that might follow. So you see, Mark, when you picked up my books that day, you did a lot more. You saved my life.”
