[单选题]More than three years after moving from Australia to this remote part of England, we are still learning how things are done here. Not too long after we arrived and unpacked, we were invited for a drink on Sunday morning by a retired couple nearby. We got there about noon, to find the living-room crowded—lots of chat and discussions, and on all a very jolly occasion. Trouble was, there was no food—no self-respecting Australian would regard a tray of crisps as food. In Sydney, when you are invited for a drink any time after midday on a Sunday, you know you will be fed as well as watered and you plan accordingly. Meaning the hard-worked little woman makes no plans to cook lunch because you are eating out. By one-fifteen my stomach was sending up please explain to me. Even the crisps had gone. There was nothing we could do except wait, and wonder if the hostess was going to perform. some magic and feed us fashionably late. Then, as quickly as if word had spread that there was free beer at the local pub, the room emptied. By one-forty-five there were only a few guests left, so we decided to go home. Tinned soup for lunch that day because the little woman was not really interested in real cooking for us. A few weeks ago we were invited out for supper and the hostess suggested 8.15. Ah, we thought greedily, this is going to be the real thing. We dressed with some care—I putting on a dark suit—and arrived on time. My wife looked pretty good, I thought—a little black dress and so on. But when we walked in I had a terrible feeling we had got the night wrong because the hostess was dressed in a daytime kind of way and the husband was in jeans and an open-neck shirt. But no, we were greeted and shown into the sitting-room. After a drink I looked around and saw that this was indeed a superior cottage because it had a (more or less) separate dining-room. But there were no signs of a table-setting. Not again! I thought. Were we meant to eat before we came? I decided that in future my wife and I would always carry a chocolate bar. About 9.28 our hostess went out of the room, saying something about food. Ten minutes later she returned and asked us to follow. We were led out to the kitchen. There on the table were country-style. plates and a huge bowl of soup, rough bread and all the makings of a simple meal. And that is what it was. In other words, we had not read the signals right when we were invited for supper. If they want you to come to dinner, they say so, and you know that means dark suits and so on. If they mean supper, they say it, and you get fed in the kitchen. If they make such a distinction between dinner and supper, does this mean we were not worth making an all out effort for? Candles, best silver and all the restIt is enough to give a person a complex. When you think about it, it's pretty depressing. They must use the dining-room sometimes, because they had all those high-backed chairs and candle-holders.

[单选题]On March 26, 1999, I became a new staff member of the Los Alamos National Laboratory. I committed the rest of my scientific future there despite the allegations of espionage leveled at one of its weapons scientists, Wen Ho Lee, who, notably, has never been and may never be officially charged. I valued the accomplishments of its distinguished scientists and was confident its able leaders would receive the political support they needed from Washington to cope with the potential damage to its programs arising from the scandal. But in the months since then that support has come into question—and the damage has become real. Washington's reaction to the incident has created an atmosphere of suspicion, which, coupled with efforts to restrict scientific interchange and reduce funds for key research, threaten the essence of the lab—its ability to provide the kind of science-based security that has made it a national treasure. Los Alamos burst upon the national consciousness on Aug 6, 1945, the day it was announced that the atomic weapon dropped on Hiroshima had been developed by scientists working at the lab under the direction of Robert Oppenheimer. The secret of their success was an almost magical mix of three key ingredients: the quality and dedication of the researchers, an open scientific environment that promote collaboration and Oppenheimer's brilliant leadership. That excellence, openness and leadership have largely been maintained in the ensuing 54 years under the enlightened management of the University of California. During the cold war, when national security demanded that we have a competitive edge over the Soviets in nuclear weapons and weapons-related research, Los Alamos led the way. When it became evident that science-based national security depended on world leadership in science, the lab rose to the challenge. It developed an outstanding program to attract the best young researchers and established world-class trans-disciplinary centers for pure and applied scientific research. Indeed, what brought me to Los Alamos was the new Institute for Complex Adaptive Matter, established to work on what promises to be the most exciting science of the new millennium— the search for the higher organizing principles in nature that govern emergent behavior. in matter. But in the past six months members of Congress and the Washington bureaucracy have put the scientific environment at Los Alamos seriously at risk. With the laudable goal of improving the security of classified research, they have attempted to impose inefficient micromanagement strategies while decreasing funding for vital research. As Sen. Pete Domenici, Republican of New Mexico, wrote recently to a Horse colleague, The House action is irresponsible. The damage, he said, would be as serious and more assured than the suspected damage that may have been caused by Wen Ho Lee. Some of that damage has already been done. By my count there's been a 60 percent drop in the number of top researchers accepting postdoctoral fellowships at the lab. Promising young staffers are leaving for university and industry jobs, while leading university scientists have refused to be considered for key administrative positions at Los Alamos. Then, too, there's the loss of the young scientist from China who wanted to come to the lab to work with me this fall. Despite his outstanding record of scientific publication and glowing letters of recommendation, I felt obligated to discourage him from entering the postdoctoral competition. In the current atmosphere, I felt his every move would be monitored. But I wonder whether we've lost a chance to attract to America a major contributor to science—and a potential Nobel laureate. Washington must never forget that science is done by scientists, not by computers. It is vital to build security barriers in physical space and cyberspace to protect classified information. But science is not don A.he appreciated its scientific environment B.he esteemed its distinguished scientists and treasured their accomplishments C.it obtained support from Washington D.its leaders were all able to cope with the potential damage to its programs.
