Conventional computer models of the atmosphere have limited value in predicting short lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the subtle (微妙的)atmospheric changes that come before these storms. In most nations, for example, weather - balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events. Until recently, the observation intensive approach needed for accurate, very short - range forecasts, or "Now casts", was not feasible. The cost of e quipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were hard to overcome. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modem computers can quickly compile and analyze this large volume of weather information. Meteorologists(气象学者) and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, now casting is becoming a reality. The word "exceeded" in paragraph 1 most probably means ______. A．added up to B．were more than C．were about D．were less than

"Mary, didn&39;t you ever wonder what you are really like？ Well, you now have that girl&39;s opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said. " I did as he directed and discovered to my surprise that about half the things were true. Some of them I couldn&39;t change (like being skinny), but a good number I could and suddenly wanted to change. For the first time in my life I got a fairly clear picture of myself. I brought the list back to Daddy. He refused to take it. "That&39;s just for you," he said. "You know better than anybody else the truth about yourself, once you hear it. But you&39;ve got to learn to listen, not to close your ears in anger or hurt. When something said about you is true you&39;ll know it. You&39;ll find that it will echo inside you. " Daddy&39;s advice has returned to me at many important moments. 1、What did the girl&39;s enemy like to do？ A.Talking with her. B.Pointing out her weak points. C.Reporting to the teacher. D.Quarrelling with her. What did the girl do when she could no longer bear her enemy？A.She turned to her father. B.She cried to her heart's content. C.She tried to put up with her again. D.She tried to be her friend. Why did the girl's father ask her to make the list？A.He wanted to keep the list at home. B.He didn't know what the girl's enemy had said. C.He wanted the girl to talk back. D.He wanted her to check if she really had these weak points. What can we infer from reading the passage？A.The girl benefited from her father's advice.

The strikes are serious protests about serious issues, but I'm struck, as so often on these occasions, by something much more mundane. People are once again talking to people; strangers are going out of their way to befriend strangers, allies for a week or two in their shared frustration. Parisian motorists, even, normally the most competitive of individualists, have been seen leaving notes in their parked cars saying where they are going and when they expect to leave in case anymore wants a lift. Remove the technology of modem life, it seems, and we often start to be nice to one another again. Technology can isolate us, for all its benefits. It started, I guess, with the chimney. Before there were chimneys, we all had to huddle together in one room Just to keep warm, master and maid, cowman and son of the house. Then some unknown genius came up with the idea of the chimney, and the social stratification of society increased dramatically as all withdrew into their own quarters. Central heating, which is, more truthfully, decentralized heating, made it worse, and now we have our walkmans, our microwaves, or, if we' re really trendy, the Internet and e-mail. You can get by, these days, without actually speaking to anyone at all. Just the odd grunt to show that you' re alive ! I liked the survey which asked teenagers how they laid a table for a meal. Did they put the knife on the fight and the fork on the left, or did they put them both together？ And 40 percent said one and 20 percent the other, but 40 percent didn't know! They had never sat down at a table together but had always, as they say, been grazers, helping themselves from the fridge and carrying the food off to their own comer to munch on their own. If progress means that we don' t need to talk to each other anymore, then I'm getting worried. You can' t begin to love and befriend your neighbors if you never talk to them, and vice versa, they can't love you. It becomes a recipe for a world of solitaries. But most of us weren't destined to be hermits. People need people to be truly people, as the Parisians, in spite of all their frustrations, are discovering again this week. "Try walking instead" was my motto for this morning, but perhaps the motto for us all this festive month might be "Turn it off, whatever it is, and try talking instead!" According to the author, the advent of modem technology may NOT______. A．isolate us from the test of the society. B．enable us to enjoy a much more convenient life. C．leave people alone so that they may become truly people. D．help people become grazers who are used to helping themselves from the fridge and carrying the food off to their own comer to munch on their own.

Man’s mind allows long—range planning and thinking.It enables such long—range planning as required for farming，hunting，and tool making.These efforts require the ability to form. concepts of long—term cause and effect chains.“I need t0 make a spear tonight SO I can hunt tomorrow and have food for the next 7 days.”There may be environments where people could survive for a while without long—range planning，but without the results 0f knowledge like spears，fire，and 0ther technologies，people would get out—bred by Other animals and die out。 Man’s mind is his tool for survival，but like all tools，it must be properly used.The mind makes good use 0f knowledge，and knowledge can only be 0btained through reason.Without reason，there is no knowledge，and thus no survival。 You must recognize reality and act in accordance with it in order t0 be successful.To the extent that you use reason as your method of judgment in knowledge and action，you will survive and flourish .If you ignore or escape form. reality you will suffer and die. It is very important t0 note that survival by reason requires the freedom to act according t0 your reason.That is why people d0 not develop well in the control of others，and can not survive when they are subject t0 foree that destroys their ability to act on reason. 26.It is his mind that enables a farmer t0 know how to_______. A.make spears B.hunt for animals C.make iron tools D.cultivate crops 27.The first two paragraphs show that man’s mind______. A. is his basic means Of survival B. enables him to act at will C. is used to protect themselves D. helps him 100k int0 reality 28. In order to survive，man should_______. A.be conquered by 0thel"allimals B.make a long—range plan for the future C.1earn to recall knowledge D.1earn to think reasonably 29.Without the results Of knowledge like spears，fire，and Other technologies，people_____. A.Could only survive for7 days B.would kill off a11 the animals C.would be controlled by 0thers D.would disappear from the earth 30.It is reasonable that if people want to survive，they should______. A.develop well in the control of others B.ignore or escape from reality C.have freedom to act on reason D.be subject to certain environments
