With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother Todd. He ran downstairs through the smoke filled house to push and pull at Karen and Todd until they sat up. Then he helped each one through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, collapsed on the lawn. The nine-year-old raced back into the house and upstairs to his mother's room. He found it impossible to wake her up. Mrs. Kreamer, a victim of the smoke, was unconscious, and there was nobody to help Glenn carry her to the garden. But the boy remained calm and, as a fireman said later, "acted with all the self-control of a trained adult." On the bedroom telephone, luckily still wording, Glenn called his father and, leaving Mr. Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother. First he filled a bucket with water from the bathroom and threw water over his mother and her bed. Then, with a wet cloth around his head he went back to the garden. He could hear the fire engine coming up, but how would the firemen find his mother in the smoke-filled house where flames had almost swallowed up the ground floor？ Grasping firmly a ball of string from the garage, Glenn raced back into the house and dashed upstairs to his mother's room. Tying one end of the string to her hand he ran back, laying out the string as he went, through the hall and back out into the garden. Minutes later he was telling fire chief John Coughlan: "The string will lead you to mother." Mrs. Kreamer was carried to safety as the flames were breaking through her bedroom floor. Why did Glenn run downstairs first？ A．He wanted to find out what was happening. B．He was worded about his mother's safety. C．He wanted to save his sister and brother. D．He went to see if his father had come back from work.

For the purposes of this problem assume that there was an instantaneous release of 10⁷curies of radioactive gases (and fine particles, which are assumed to remain in the atmosphere and not settle out). Then estimate the maximum ground level concentration of radioactive gases (curies/m³) when the radioactive cloud from the accident got to Sweden. Make the following assumptions: (1) Ignore decay of the radioactive gases (i.e., assume their half-lives were infinite). (2) Assume the distance between Chernobyl and Sweden is 1000 km. (3) Assume that the wind speed was 3 m/s and the stability class C. (4) Assume that the mixing height was 2000 m. (5) Assume that mlXmg in the x direction(up and down the direction of the wind) has the same intensity as miXing in the y(crosswind)direction.

Scientists say that something very serious is happening to the earth. It will begin to get __56__ in the following years. There will be major changes in ___57__ in the new century. Coastal waters will have a __58__ temperature. This will have a __59__ effect on agriculture. In northern areas, the __60__ season will be ten days longer by the year 2010. However, in warmer areas, it will be too dry. The __61__ of water could __62__ by eighty percent. This would __63__ a large decrease in agriculture production. World temperature could __64__ two degrees centigrade by the year 2040. However, the increase could be three times as great in the Artic and Antarctic area. This could cause the __65__ sheets to melt and raise the __66__ of the oceans __67__ one to two meters. Many coastal cities would be __68__ water. Why is this happening？ There is too __69__ carbon dioxide in the air. __70__ oil, gas and coal burn, they create large amounts of carbon dioxide. This carbon dioxide lets __71__ enter the earth’s atmosphere and __72__ the earth. However, it doesn’t let as much heat __73__ the atmosphere and enter space. It’s like a blanket. The heat __74__ the sun can pass through the blanket to warm the earth. The heat __75__ there and can’t escape through the blanket again. Scientists call this the green-house effect. 56.

away, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me. As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away from any possible robbers (抢劫犯). Very few people were still out except a few sad-looking homeless people under blankets. About a block from my apartment (公寓房间), I heard a sound behind me: I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk. Suddenly I wasn't cold or tired anymore. I ran out of the door and back to where I'd heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found. Just as I was about to give up the search, I heard the garbage truck (垃圾车) pull up to the sidewalk next to me. When a voice called from the inside, "Lily Smith？" I thought I was dreaming. How could this man know my name？ The door opened, and out jumped a small red-haired man with an aroused look in his eyes. "Is this what you're looking for？" he asked, holding up a small square shape. It was nearly 3 a.m. by the time I got into bed. I wouldn't get much sleep that night, but I had gotten my wallet back. I also had gotten back some enjoyment of city life. I realized that the city couldn't be a bad place as long as people were willing to help each other. How did the writer feel when she was walking home after work？ A．Cold and sick.
