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.

W: Thank you. M: Meyers, how do you describe your film？ Are you satisfied with it？ W: Well, I am happy to see it top the U.S. weekend box office. Have you seen the film？ Ha, it tells the story of Nick Marshall, a Chicago advertising executive. He acquires the power to read women's minds, not just what they say but also what he hears them think. That's amazing, isn't it？ I like the way Gibson interprets his role. M: Yeah, Marshall regards himself as a gift to women. I saw the movie. Then why do you choose Mel Gibson？ We know, audiences usually see him playing a man with a strong typical man side, such as in his previous action movies like “Brave Heart”, while “What Women Want” is what you termed as an old-fashioned romantic comedy. W: You are right．That's precisely why I choose him. Gibson has been known as a joker on the set and a fan of silly comedy, but has not done many romantic comedies. I just want him to display his“feminine”potential in“What Women Want”. And I am grateful to see that he has done a good job. M: What do you want audiences to learn from this film？ W: About Women. We should learn about women. They are individuals. What they appreciate is when you make the effort, even if you are not quite getting something they say. (23) A．Movie on Display. B．Movie on the Show. C．Best-selling Movie. D．Shining Movie Stars.

"There is no excuse for this, "President Bill Clinton had already chided." These results are, entirely unacceptable, "admonished the secretary of education. The head of the National Education Association declared U.S. schools to be in a state of crisis. And now Alberts, president of the National Academy of Sciences, said that he, too, saw in this report "all the elements of an education tragedy." "Americans have always risen to a crisis," he added. "We see clearly that the future is threatened. 2. Let us act now to heed this important wake-up call." And so, with editorial writers and educators across the country obligingly sounding the alarm, American education lurched yet again into crisis mode. It is a cyclical ritual, repeated in every decade since the 1940s, observes Gregory William of the University of Toledo. 3. The launch of Sputnik in 1957 set off an orgy of anxiety culminating in Admiral Hyman Rickover's 1963 book American Education, A National Failure, in which he famously predicted that "the Russians will bury us" thanks to their more rigorous science and math courses. 4. Beginning with the 1983 publication of A Nation at Risk, one blue-ribbon panel after another warned that massive educational failure had ceded the United State's technological lead to Japan and other competitors—a conclusion that proved premature. 5. Although the particulars vary from one education crisis to the next, the episodes are connected by common threads. Each has surged into public discourse on an unrelenting torrent of angst flowing from the educational research profession, William says. Combing through the education literature of the past 30 years, he recently turned up more than 4,000 articles and books in which scholars declared some sort of crisis in the schools—but rarely bothered to spell out what cataclysm was imminent. Each episode has also eaten away at public confidence in schools, which fell 38 percent from 1973 to 1996, according to surveys by the National Opinion Research Center.
