1、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building and that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home forblind people in Sommersetand a resource centre forthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It ______ them nearly four minutes to find the doorwithout a sound alarm, but only 15 seconds with one. Withington studies how the brain processes sounds at the university. She says that the source of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising orfalling frequencies to indicate whether people should go up ordown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【单选题】
A.has taken
B.takes
C.took
D.willtake
正确答案:C

2、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 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 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 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.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。

5、Sharing SilenceDeaf teenagers Orlando Chavez and German Resendiz have been friends since kindergarten (幼儿园). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak and hear.Orlando lost his hearing at the age of one. German was born deaf, and his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kinder garten."We were in a special class with about 25 other deaf kids," German remembered. "Before then, I didn\'t know I was deaf and I was different.""Being young and deaf in regular classes was very hard," signs Orlando. "The other kids didn\'t understand us and we didn\'t understand them. But we\'ve all grown up together, and today, I\'m popular because I\'m deaf. Kids try to communicate with me."Some things are very difficult forthe two boys. "We can\'t talk on the phone, so if we need help, we can\'t call an emergency service," German signs. "and we can\'t orcerfood in a drive - thru."Despite of their difficulties, the two boys have found work putting food in bags at a local supermarket.They got their jobs through a "workability" program, designed forteenagers from local schools with different types of learning disabilities.German has worked in the supermarket since August, and Orlando started in November."The other people who work here nave been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we\'ve learned a lot and we\'re getting better."The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute forthe Deaf in New York.Both boys are happy to ______.【单选题】

6、About one million Americans are diagnosed annually with skin cancer.【单选题】
A.every year
B.severely
C.actively
D.every month
正确答案:A
答案解析:题干大意:每年大约有100万美国人被诊断为皮肤癌。画线词annually:每年。选项中,every year:每年。severely:严重的。如:The report says the drugs had meaningful results only in the most severely depressed patients. 这个报告指出药物只是对于最严重的抑郁症患者有显著效果。actively:积极地。如:Just as a rider\'s weight shifts can help sustain the equilibrium of a wobbly bicycle, actively balancing the lift forces on each wingtip is key to aircraft roll control. 骑自行车的人移动重心有助于稳定摇晃的自行车,就飞机而言也一样,要控制转动动作,关键就在于主动平衡左右翼尖的升力。
7、WaterThe second most important constituent (构成成份) of the biosphere (生物圈) is liquid water. This can only exist in a very narrow range of temperatures, since water freezes at 0℃ and boils at 100℃. Life as we know it would only be possible on the surface of a planet which had temperatures somewhere within this narrow range.The earth\'s supply of water probably remains fairly constant in quantity. The total quantity of water is not known very accurately, but it is about enough to cover the surface of the globe to a depth of about two and three - quarter kilometers. Most of it is in the form of the salt water of the oceans about 97 percent. The rest is fresh, but three -quarters of this is in the form of ice at the Poles and on mountains, and cannot be used by living systems until melted. Of the remaining fraction, which is somewhat less than one percent of the whole, there is 10 -20 times as much stored underground water as there is actually on the surface. There is also a tiny, but extremely important fraction of the water supply which is present as water vapour in the atmosphere.Water vapour in the atmosphere is the channel through which the whole water circulation (循环) of the biosphere has to pass. Water evaporated (蒸发) from the surface of the oceans, from lakes and rivers and from moist (潮湿的) earth is added to it. From it the water comes out again as rain orsnow, falling on either the sea orthe land. There is, as might be expected, a more intensive evaporation per unit area over the sea and oceans than over the land, but there is more rainfall over the land than over the oceans and the balance is restored by the runoff from the land in the form of rivers.Liquid water only exists ______.【单选题】
A.in the center of the earth
B.on the surface of our planet
C.in a very narrow range of temperatures
D.in the coastal areas of the earth
正确答案:C
答案解析:本题难度不大,答案依据比较明显,答案依据是文章第一段第二句,谈到液态水只存在于很小的温度范围内(零度到一百度),回来看选项,C项是其近义解释,所以正确,答案是C。

答案解析:lure:吸引、诱惑,与attraction(吸引)意思相近;error:错误;function:作用、功能:miracle:奇迹。
10、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 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 ______ 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.warn
B.suggest
C.invite
D.check
正确答案:A
答案解析:空白所在的句子说“专家……我们现在还不能这么做”,因此判断A(警告)是答案。
