2、Animal\'s "Sixth Sense"A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for disasters, experts said.Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island\'s coast clearly ______ wild beasts, with no dead animals found."No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy director of Sri Lanka\'s Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka\'s biggest wildlife reserve and home to hundreds of wild elephants and several leopards."There has been a lot of scientific evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal behavior assistant at Johannesburg Zoo. "There have been no specialist studies because you can\'t really test it in a lab or field setting," he told Reuters. Other authorities concurred with this assessmetn."Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal "sixth sense" -or some other mythical power-is an enduring one which the evidence on Sri Lanka\'s ravaged coast is likely to add to. The Romans saw owls as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.【单选题】

A.missed

B.protected

C.raised

D.caught

正确答案:A

答案解析:本句对比海啸造成人员伤亡和动物逃脱海啸这一现象。答案应该是选项A，其他选项中三个词的词义与上下文都不相配。

3、A Bad IdeaThink you can walk, drive, take phone calls, e - mail and listen to music at the same time 7 Well, New York\'s new law says you can\'t. And you\'ll be fined $ 100 if you do so on a New York city street. The law went into force last month, following research and a shocking number of accidents that involved people using electronic gadgets (小巧机械) when crossing the street.Who\'s to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."The young people are often considered the great multitaskers. However, an Oxford University research suggests this perception is open to question. A group of 18 to 21 years old and a group of 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone call or an instant message, the older group matched the younger group in speed and accuracy.It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $ 650 billion a year. _____. The surveys conclude that 28 percent of the workers\' time was spent on interruptions and recovery time before they returned to their main tasks.【单选题】

A.Talking on a cell phone while driving brings you joy anyway.

B.The estimate is based on surveys with office workers.

C.The younger group did 10 percent better when not interrupted.

D.However, an Oxford University research suggests this perception is open to question.

E.Scientists say that our multitasking (多任务处理) abilities are limited.

F.And you\'ll be fined $ 100 if you do so on a New York city street.

正确答案:B

答案解析:本题有一定的难度，需要认真阅读文章，理解好句意。可用排除法和代入法。本题的下文谈到了对（办公室）职工做的一次调查，涉及具体内容，所以可以推断此处应该是概括性的句子，来引导下文，而且和职工调查有关，回来看选项，把B代入文中，符合逻辑，答案是B。

4、Animal\'s "Sixth Sense"A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa, Wild animals, ______, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for disasters, experts said.Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island\'s coast clearly missed wild beasts, with no dead animals found."No elephants are dead, not even a dead rabbit.

A.therefore

B.however

C.although

D.whatever

正确答案:B

答案解析:第一句说的是海啸造成了巨大的人员伤亡，第二句说的是动物能逃脱海啸的袭击。两句的意思相反，所以要用however以承接上文。

5、Will We Take Vacation in Spaces?When Mike Kelly first set out to build his own private space-ferry service, he figured his bread-and-butter business would be lofting (发射) satellites into high-Earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly, who runs Kelly Space & Technology out of San Bemardino, California. "I realized that real market is in space tourism."According to preliminary market surveys, there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington, Virginia, has taken more than 130 deposits for a two-hour, $98, 000 space tour tentatively and somewhat dubiously (可疑地) set to actor by 2005. Gene Meyers of the space Island Group says: "Space is the next exotic(风光奇特的) vacation spot. "This may all sound great, but there are a few hurdles (困难). Putting a simple satellite into orbit with no oxygen, life support or return trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. And that doesn\'t include the oust of insuring rich and possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entire group of entrepreneurs trying to corner (垄断) the space-tourism market have between them "just enough money to blow up one rocket."The U. S. space agency has plenty of money but zero interest in mailing space less expensive for the little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that is inexpensive, safe and reliable. Kelly Space\'s prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in Redwood City, California, has a booster with rotors to make a helicopter-style return to Earth; Kistler Aero-space in Kirkland, Washington, is piecing together its versions from old Soviet engines, shuttle-style thermal protection tiles and an elaborate parachute system. The first passenger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can\'t be too prepared, for a trip to that galaxy far, far away. For those who are intent on joining the 100-mile high club, Hilton and Budget are plotting to build space hotels. Before the Russian spaceship Mir came down, some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space, and if you are thinking of staying in it, you may want to check the Michelin ratings before booking yourself a suite. Space Adventure in Arlington has taken 130 deposits totaling $98,000 for a two-hour space tour. 【单选题】

A.Right

B.Wrong

C.Notmentioned

正确答案:B

答案解析:第2段第2句的意思是：每人交100万美元的定金，而不是总共98 000美元，从这句话中可以看出历时两个小时的太空旅行计划在2005年，该旅行是试验性的，并且在一定程度上令人质疑。因此题干的说法是错误的。

6、A beautiful woman attended to me in that store yesterday. 【单选题】

7、Walking to Exercise the BrainDo you think sitting and studying all the time will improve students grades? Think again. Getting some exercise may help, too.New research with older people suggests that taking regular walks helps them pay attention better than if they didn\'t exercise.Previous research had shown that mice learn, remember and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don\'t. Their brain cells also make more connections.Neuroscientists (神经科学家) from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true for people. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked I mile. Then, participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task, and their answers were just as accurate as their less - fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions.In a second study, 15 elderly people who completed a 6 - month aerobic - training (有氧运动) course were faster at attention tasks compared with 14 seniors who just did stretching and toning (韵律操) exercises for the same amount of time.So, even going for a walk every 2 or 3 days for just 10 to 45 minutes can help. That should be good news for the elderly.The effects of exercising on the brains of younger people haven\'t been studied yet. Still, it can\'t hurt to take occasional breaks and go for a walk or run around with friends. Whatever you do, though, don\'t try to read and walk at the same time. You could end up hurting yourself!Walking regularly helps elderly people ______.【单选题】

A.lose weight

B.become happier

C.concentrate better

D.look younger

正确答案:C

答案解析:本题难度不大，找到答案依据不难。答案依据在文章第二段。第二段谈到新的研究表明，相对于不锻炼，经常散步有助于帮助老年人更好集中精力，回来看选项，很明显，C是近义解释，是答案。

8、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 line for the 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 ______. 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.rapidly

B.smoothly

C.slowly

D.hardly

正确答案:A

答案解析:空白所在的句子说“他（虚拟司机）……反应”，结合前句内容（什么是虚拟司机最大的优势？）及常识判断A（迅速地）最可能成为答案。

10、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 _____.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight or shade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. 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 for their 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.star

B.Earth

C.space

D.planet

正确答案:C

答案解析:本题难度较大，考查词义辨析，干扰项干扰较大。根据全文的逻辑，文章此处是讨论的宇宙空间范围内的温度，而不仅仅是地球上或星体的温度，最佳答案是C。
