Albert Einstein, whose theories on space time and matter helped unravel (解决) the secrets of the atom and of the universe, was chosen as "Person of the Century" by Time magazine on Sunday.
A man whose very name is synonymous (同义的) with scientific genius, Einstein has come to represent more than any other person the flowering of 20th century scientific though that set the stage for the age of technology. "The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic, but technological—technologies that flowed directly from advances in basic science," wrote theoretical physicist Stephen Hawking in a Time essay explaining Einstein&39;s significance. __________ (46)
Time chose as runner-up President Franklin Roosevelt to represent the triumph of freedom and democracy over fascism, and Mahatma Gandhi as an icon (象征) for a century when civil and human rights became crucial factors in global politics.
"What we saw was Franklin Roosevelt embodying the great theme of freedom&39;s fight against totalitarianism, Gandhi personifying (象征, 体现 ) the great theme of individuals struggling for their rights, and Einstein being both a great genius and a great symbol of a scientific revolution that brought with it amazing technological advances that helped expand the growth of freedom," said Time Magazine Editor Walter Isaacson.
Einstein was born in Ulm, Germany in 1879. __________ (47) He was slow to learn to speak and did not do well in elementary school. He could not stomach organized learning and loathed taking exams. In 1905, however, he was to publish a theory which stands as one of the most intricate examples of human imagination in history. __________ (48) Everything else- mass,weight, space, even time itself-- is a variable (变量) . And he offered the world his now-famous equation (公式 ) : energy equals mass times the speed of light squared--E= mc2.
__________ (49) "There was less faith in absolutes, not only of time and space but also of truth and morality." Einstein&39;s famous equation was also the seed that led to the development of atomic energy and weapons. In 1939, six years after he fled European fascism and settled at Princeton University, Einstein, an avowed pacifist, signed a letter to President Roosevelt urging the United States to develop an atomic bomb before Nazi Germany did. __________ (50) Einstein did not work on the project. Einstein died in Princeton, New Jersey in 1955.
A. "Indirectly, relativity paved the way for a new relativism in morality, art and politics,"Isaacson wrote in an essay explaining Time&39;s choices.
B. How he thought of the relativity theory influenced the general public&39;s view about Albert Einstein.
C. "Clearly, no scientist better represents those advances than Albert Einstein."
D. Roosevelt heeded the advice and formed the "Manhattan Project" that secretly developed the first atomic weapon.
E. In his early years, Einstein did not show the promise of what he was to become.
F. In his "Special Theory of Relativity", Einstein described how the only constant in the universe is the speed of light.
A、divestment
B、harvest
C、price signaling
D、leadership
E、capacity control

A．Tree leaves die of lack of water from acid rain.
B．Spruce growth is accelerated by acid rain.
C．Acid rain kills the microorganisms within the soil.
D．Beech trees suffer more than other trees in acid rain.
A．It cannot be imagined that a child can experiment with objects.
B．It is an easy task for a child to do experiments with objects.
C．A child who likes doing experiments with objects is likely to be an inventor.
D．It encourages children to perform. experiments with objects.
听力原文：Narrator Listen to part of a lecture in a biology class. Professor So today were gonna talk about animal experimentation. Do you know why animal experimentation is scientific fraud？ I am an animal lover. Although I have never personally performed vivisection or experimented on animals, I have many friends and former colleagues who have done so. Almost every single one of these people feel an enormous burden and responsibility to see that the animals suffer as little as possible and that no animal in an experiment loses its life for nothing. Scientists for the most part are not in it for the money or the fame, both of which most scientists NEVER see much of, by the way. They want to help make the world a little better while exercising their innate curiosity. For you to demonize the many scientists who experiment while trying to find cures for diseases is really unfortunate and demonstrates that you are terribly uninformed. Am I saying that human life is more important than animal life？ I am not. Animal experimentation is also performed on animals for the betterment of animal health. Am I saying that all animal experimentation is necessary？ Absolutely not. Some of it is very likely a sad waste of animal lives and the cause of needless suffering, and certainly a waste of limited research funding. Am I saying that some of this work has saved human lives？ Absolutely. Satan Jr.s example(insulin)is one such case. As an animal lover, I will be most pleased when the use of animals in science is no longer performed. Do you really want to help make animal experimentation a memory？ Then become a scientist and develop alternative disease models and non-animal based remedies and then make your research widely available to other scientists. If you had really done your homework and focused on something beyond your anger and hatred, you would see that many scientists have already done just this. You can also donate time and/or money to organizations that support the development of alternatives to animal testing. Science, like so many other fields, is slow to evolve. It will take time. The great advances in science that have given us the high standard of medical care humans and animals enjoy today have come from clinical observation, in vitro research, epidemiology, autopsies, serendipity, computer and mathematical modeling, technology, tissue research using the tissue from the species being studied, molecular biology and genetics, post-marketing drug surveillance, the basic sciences of maths, chemistry and physics and the specialization of medical care, including the specialization of physicians and veterinarians. The animal experimentation lobby, however, spends millions annually to convince the public that all medical advances are directly due to animal experiments. Furthermore, animals are not able to communicate about any side effects they may be experiencing. At least half of the side effects experienced by most drugs cannot be accurately communicated by animals. In April 1998, the Journal of the American Medical Association reported on a study which showed that more than 2 million Americans become seriously ill every year because of toxic reactions to correctly prescribed medicine and 106 000 die from those reactions, making drug side effects the sixth most common cause of death in this country! Legal drugs kill more people per year than all illegal drugs combined. People expect me and want me to argue against vivisection on a purely scientific basis. I can do that. However, I cannot and will not forgo the ethical argument. For when all is said and done, I believe that research on animals is ethically wrong, and that nothing "good" can ever come out of something so morally debased. I often cite the hypothermia experiments done on Jews in the concentration camps during World War II. This experimentation on helpless, non-consenting humans who suffered and died as a result of these experiments actually taught scientists a great deal about treating hypothermia in humans. But was it right？ I would argue that it was absolutely wrong, no matter how much useful information we garnered. Now get ready to answer the questions. You may use your notes to help you answer. 18. What aspect of animal experimentation does the professor mainly discuss？ 19. What does the professor say about animal experimentation？ 20. What is the evidence to deny animal experimentation？ Listen again to part of the lecture. Then answer the question. Professor Do you really want to help make animal experimentation a memory？ Then become a scientist and develop alternative disease models and non-animal based remedies and then make your research widely available to other scientists. 21. What does the professor imply when he says this？ Professor Do you really want to help make animal experimentation a memory？ 22. Why does the professor say this？ Professor For when all is said and done, I believe that research on animals is ethically wrong, and that nothing "good" can ever come out of something so morally debased. 23. How does the professor remind students of the cruelness of animal experimentation？Narrator Listen to part of a lecture in a biology class. Now get ready to answer the questions. You may use your notes to help you answer.
