In practice, what often happens is that a new theory is devised that is really an extension of the previous theory. For example, very accurate observations of the planet Mercury revealed a small difference between its motion and the predictions of Newton's theory of gravity. Einstein' s general theory of relativity predicted a slightly different motion from Newton's theory. The fact that Einstein's predictions matched what was seen, while New ton's did not, was one of the crucial confirmations of the new theory. However, we still use Newton's theory for all practical purposes because the difference between its predictions and those of general relativity is very small in the situations that we normally deal with. (New ton's theory also has the great advantage that it is much simpler to work with than Einstein' s!)
A good title for this passage is ______.
A.The History of Physical Science
B.Karl Popper's Physical Theory
C.The Philosophy of Science
D.Einstein's Theory of Science

听力原文: As is known to all, scientists and philosophers had studied the human body and its functions from very early times. Unfortunately, many of the ideas and theories, correct and incorrect, were accepted without question for a great number of years. But by the 16th century, knowledge gained through chemical experiments was beginning to make some people think more deeply about how the human body works.
A most important medical discovery was made by William Harvey in 1628. He found out that the blood is circulated round the body in one direction only by the pumping action of the heart. It had previously been incorrectly thought that the blood moved with a backward and forward motion.
Early in the 17th century a new instrument came into use that was to open up a whole new area in the study of medical and scientific matters. This was the microscope.
The first instruments were not very efficient. They were able to magnify only a very small part of the object and this was always surrounded by rings of colored light. Nevertheless a great step forward had been taken which was of vital importance for future research and development.

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

Where did the British people come from? This is an extraordinary interesting question, since they are a mixture of many different races, and all these races invaded Britain before at various times from Europe. Nobody knows very much about Britain before the Romans came during the first century B. C., but there had been at least three invasions before that. The first of these was by a dark-haired Mediterranean race called the Iberians. The other two were by Celtic tribes: first the Baels, whose descendants are the modern Scots and Irish, some of whom still speak the Gaelic language; and secondly the Britons, who gave their name to the whole island of Britain. These were the people whom the Romans conquered. The Romans gave the Britain in very large numbers, so the British race survived until the overthrow of the Roman Empire by the "barbarians", i. e., the numerous Germanic tribes that overran the whole of Western Europe.
According to the first paragraph, which of the following is true?
A.The British in Britain regard themselves as Europeans.
B.Chinese and Egyptian will think of white men as Europeans.
C.White men are Europeans in the eye of Americans and Asians.
D.Those who speak English are Europeans.
