1、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight orshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science forwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar _____. Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fortheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】
A.system
B.energy
C.year
D.rays
正确答案:A
答案解析:本题难度不大,考查词义辨析,但干扰项干扰不大。可以先看选项得到信息提示。根据上下文逻辑,文章此处是说“太阳系”,答案是A。
2、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all. these and can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" and "feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road and conditions ahead of it. They watch the traffic to the car\'s left and right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the right ______forthe intelligent cars, and gives instructions to the "hands" and "feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver at least needs one second to react. Besides, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time and in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【单选题】
A.line
B.lane
C.track
D.trial
正确答案:A
答案解析:空白所在的局部结构说“根据这个信息(在其附近移动的汽车的速度和位置),它为智能车选择合适的……”,因此判断A合适。
3、The researchers have just completed a study of driving situations.【单选题】
A.started
B.finished
C.changed
D.made
正确答案:B
答案解析:题干大意:研究人员已经完成了开车的学习。画线词complete:完成。选项中,finish:完成。start:开始。如:The reshuffle is a fresh start, she said. 这次改组是一个新的起点,她说。make:制作。如:We just want to make great products. 我们只是想做很多产品。change:改变。如:But this could change. 但这也可以改变。
4、Medicine Award Kicks off Nobel Prize AnnouncementsTwo scientists who have won praise forresearch into the growth of cancer cells could be candidates forthe Nobel Prize in medicine when the 2008 winners are presented on Monday, kicking off six days of Nobel announcements. Australian-born U. S. citizen Elizabeth Blackburn and American Carol Greider have already won a series of medical honors fortheir enzyme research and experts say they could be among the front-runners fora Nobel. Only seven women have won the medicine prize since the first Nobel Prizes were handed out in 1901. The last female winner was U. S. researcher Linda Buck in 2004, who shared the prize with Richard Axel. Among the pair\'s possible rivals are Frenchman Pierre Chambon and Americans Ronald Evans and Elwood Jensen, who opened up the field of studying proteins called nuclear hormone receptors. As usual, the award committee is giving no hints about who is in the running before presenting its decision in a news conference at Stockholm\'s Karolinska Institute. Alfred Nobel, the Swede who invented dynamite, established the prizes in his will in the categories of medicine, physics, chemistry, literature and peace. The economics prize is technically not a Nobel but a 1968 creation of Sweden\'s central bank. Nobel left few instructions on how to select-winners, but medicine winners are typically awarded fora specific breakthrough rather than a body of research. Hans Jornvall, secretary of the medicine prize committee, said the 10 million kronor(US$1. 3 million) prize encourages groundbreaking research but he did not think winning it was the primary goal forscientists. "Individual researchers probably don\'t look at themselves as potential Nobel Prize winners when they\'re at work," Jornvall told The Associated Press. "They get their kicks from their research and their interest in how life functions. "In 2006, Blackburn, of the University of California, "San Francisco, and Greider, of Johns Hopkins University in Baltimore, shared the Lasker prize forbasic medical research with Jack Szostak of Harvard Medical School. Their work setthe stage forresearch suggesting that cancer cells use telomerase to sustain their uncontrolled growthWhich is NOT true of Alfred Nobel?【单选题】
A.He was from Sweden.
B.He was the inventorof dynamite.
C.He established the prizes in his will.
D.He gave clear instructions on how to selectwinners.
正确答案:D
答案解析:短文的第7段说到,对于如何选拔获奖者诺贝尔并没有多少交代。
5、Medical facilities are being upgraded.【单选题】
A.renewed
B.repaired
C.improved
D.increased
正确答案:C
答案解析:题干大意:医疗设备正在升级。upgrade:提高,升级,因而有“改进”的含义。improve:提高,改进。renew:更新。repair:修理。increase:增长。故答案选C。
