2、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 ______ 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 took 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.without

B.with

C.having

D.selling

正确答案:B

答案解析:通过阅读我们可以看出，空白后是一种装置，用来改变当火灾发生时找不到出口的危险境况，所以要表达“用……装置”的意思，只能用介词with:带着、带有。

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. _____. 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. Aｇｒｏｕｐof 18 to 21 years old ａｎｄ　aｇｒｏｕｐof 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The youngerｇｒｏｕｐdid 10 percent better when not interrupted. But when both groups were interrupted by a phone call ｏｒan instant message, the olderｇｒｏｕｐmatched the youngerｇｒｏｕｐin 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 estimate is based on surveys with office workers. 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 youngerｇｒｏｕｐdid 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:F

答案解析:本题难度不是很大。可用排除法和代入法。本题的上文谈到纽约新的法律规定在走路开车时不能打电话，发邮件，听音乐，下文转到谈新法律发生效力时间，所以可以推断此处会继续跟着上文展开阐述，应该讲如果你做了会导致什么结果，回来看选项，把F代入文中，符合逻辑，答案是F。

4、One Good Reason to Let Smallpox LiveIt\'s now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US ａｎｄ　one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). ａｎｄ　the last "official" stocks of live Virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines(疫苗). So once again there\'s a good reason to the virus, just in _____ the disease puts in a reappearance.How do we case with the mistrust of the US ａｎｄ　Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn\'t mean the idea is rejects. If the virus is useful, then let\'s wrong it the servant of all humanity make not just a part of it.【单选题】

A.put

B.keep

C.remove

D.study

正确答案:B

答案解析:本题难度不大，依据上下文逻辑，文章此处要用“保存”的意思，答案是B。

5、Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle event-flowering, the appearance of leaves, the first frog calls of the spring all around the world. But ecologists can\'t be everywhere so they\'re turning to non-scientists, sometimes called citizen scientists, fｏｒhelp. Climate scientists are not present everywhere. Because there are so many places in the world ａｎｄ　not enough scientists to observe all of them, they\'re asking fｏｒyour help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people too observe a very specific research interest-birds, trees, flowers budding, etc. ａｎｄ　send their observations to a giant ｄａｔａｂａｓｅ to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready fｏｒthe conditions where they live. All that\'s needed to become one is a few minutes each day ｏｒeach week to gather data ａｎｄ　send it in. Aｇｒｏｕｐof scientists ａｎｄ　educators launched an organization last year called the National Phenology Network. "Phenology" is what scientists call the study of the timing of events in nature. One of the group\'s first efforts relies on scientists ａｎｄ　non-scientists alike to collect data about plant flowering ａｎｄ　leafing every year. The program, called Project BudBurst, collects life cycle data on a variety of common plants from across the United States. People participating in the project which is open to everyone record their observations on the Project BudBurst website. "People don\'t have to be plant experts, they just have to look around ａｎｄ　see what\'s in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we\'ll be able to make an estimate of how plants ａｎｄ　communities of plants ａｎｄ　animals will respond as the climate changes. "What is the final purpose of Project BudBurst?【单选题】

A.To study when plants will have their first buds.

B.To find out the types ofplants in the neighborhood.

C.To collect life cycle data on a variety of common plants from across the United States.

D.To investigate how plants ａｎｄ　animals will respond as the climate changes.

正确答案:D

答案解析:问题为final purpose，所以选D，跳过C。

6、Meet Your Memory1. Memory is something that cannot be seen, touched ｏｒweighed. It is thought to be abstract. It is a ｓｅｔof skills rather than an object. Neither is there a single standard fｏｒjudging a good ｏｒpoｏｒmemory. There are a number of different ways in which a person may have a good memory.2. Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the brain until it is needed; (3) retrieval (提取) refers to getting the material back out when it is needed:3. Memory consists of at least two different processes: short - term memory ａｎｄ　long - term memory. Short - term memory has a limited capacity ａｎｄ　a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), ｏｒgrouping separate bits of information into larger chunks. Long - term memory has an almost unlimited capacity.4. One measure of memory is recall, which requires you to produce information by searching the memory fｏｒit. In aided recall, you are given cues (提示) to help you produce the information. In free - recall learning you recall the material in any order. In serial learning you recall it in the ｏｒｃｅｒit was presented ａｎｄ　in paired - associate learning you learn pairs of words so that when the first word is given you can recall the second word. A second measure of memory is recognition, in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time ａｎｄ　how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.As a measure of memory, relearning is more sensitive than ______.【单选题】

A.short - term memory

B.relearning

C.needed

D.coded

E.recognition

F.slow forgetting rate

正确答案:E

答案解析:本题难度不大，答案依据比较明显，在文章第四段倒数第二句：Relearning is generally a more sensitive measure of memory than is recognition because…谈到作为测试记忆力的方法来说，再学习比识别更灵敏，回来看选项，E项recognition符合原文句意，是答案。

7、Radiocarbon DatingNowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), ｏｒcarbon - 14 dating. One key to understanding how ａｎｄ　why something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon -12, has six protons (质子) ａｎｄ　six neutrons (中子) in its nucleus (原子核). Carbon - 14, ｏｒC - 14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of the extra neutrons ａｎｄ　energy from the nucleus.In Libby\'s radiocarbon dating technique, the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detectｏｒａｎｄ　counter. The decay rate is used to determine the proportion of C -14 atoms in the sample being dated.Carbon - 14 is produced in the Earth\'s atmosphere when nitrogen(氮) - 14, ｏｒN - 14, interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C -14 formation is thought to occur at a constant rate. Now the ratio of C -14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful fｏｒdating items back to at least 50,000 years.All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C -14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, ａｎｄ　the C -14 already present begins to decay. Over time the amount of C - 14 in the material decreases ａｎｄ　the ratio of C - 14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C -14 atoms in a sample, the older that sample is.The half - life of C - 14 is about 25 ,000 years.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题有较大难度，答案依据不明显，需要通读全文作出判断。通读全文后可以发现文章并未提及碳的半衰期是25，000年，所以本题是未提及的，答案是C。

8、A special educationVideodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, ｏｒsocializing. Almost eleven percent of the students aged 3-21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one ｏｒmore of the following ways: mentally retarded (发展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped, physically handicapped, ｏｒother health impairments. The education of these handicapped children is rewarding but challenging. A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, ａｎｄ　indefatigable (孜孜不倦) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, ａｎｄ　designers can assure absolute consistency within a program. Most important, according to special educatｏｒWilliam Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism fｏｒchildren who need graphic representations."Healey explained that deaf ａｎｄ　mentally retarded children especially have difficulty grasping figurative language ａｎｄ　higher-ｏｒｃｅｒlanguage concepts. He believes that fｏｒspecial education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken fｏｒgranted by non-handicapped persons. Complex figurative language forms such as idioms ａｎｄ　metaphors come most readily to mind as being difficult fｏｒhandicapped learners. The word "impairment" (Line 2, Para 1) probably means ____. 【单选题】

A.habit

B.disability

C.misconception

D.belief

正确答案:B

答案解析:文章第1段第2句的大意是“在该国3至21岁的学生中，约有11%的学生有…从而影响了他们接受常规教育的能力”。habit：习惯；disability：残疾；misconception：误解；belief:信仰，由句意可知B正确。

9、Houses of FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict what our home will be likeE. Future houses will have to be flexible. In thirty years\' time even more of us will be working at home. So we will have to be able to use areas of the house fｏｒwork fｏｒpart of the day ａｎｄ　fｏｒliving fｏｒthe rest. Families grow ａｎｄ　change with children arriving, growing up ａｎｄ　leaving home. The house ofthe future will have to grow ａｎｄ　change with the familyF, nothing will be as fixed as it is now. The house will always be changing to meet changing needs. Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines ａｎｄ　discuss with them what to do. Like this, "we\'ll be having a party this weekend. What food shall we cook?" ａｎｄ　the machine will tell us what food we will have to buy ａｎｄ　how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check. The house of the future will be personal-each house, you will be able to change the colｏｒofthe wall easily, you won\'t have to paint them, you\'ll be able to tell the wall to change the color! ａｎｄ　if you don\'t like the colｏｒthe next day, you will be able to have a new one. ______.【单选题】

A.you will be able to change the colｏｒofthe wall easily

B.The only thing you won\'t be able to do is moving the house somewhere else

C.ａｎｄ　the machine will tell us what food we will have to buy ａｎｄ　how to cook it

D.what our home will be likeE

E.The house ofthe future will have to grow ａｎｄ　change with the familyF

F.he kids might take their bedrooms with them as they have

正确答案:B

答案解析:意思是“也许唯一一件你不能改变的事就是把房子移到其他地方去而已”，与上文中可以随心所欲做任何事相符。

10、HalloweenHalloween is an autumn holiday that Americans celebrate every year. It means "holy evening", ａｎｄ　it comes every October 31, the evening before All-Saints Day. It used to be thought the most wonderful night of the year. It was the night when witches ａｎｄ　evil spirits came back on earth. People kept up many strange old customs in an effort to keep these evil things away. Farmers used to light big fires in their fields, ａｎｄ　the farm workers ａｎｄ　their families would walk around the fields singing old songs. Sometimes they would stop to hear the local priest offer prayers to the good spirits, ａｎｄ　ask them to help keep the evil ones away. Great care was taken that none of the farm animals were left in the fields. They would all be locked up safely in their stables, ａｎｄ　over each of the stable doors a few rowan leaves would be hung. Witches ａｎｄ　evil spirits would not go anywhere near the rowan tree. In more recent times, Halloween has become a time fｏｒthe parties, when children dress up as witches ａｎｄ　play all kinds of special games. After the games there is often a big supper with plenty of pumpkin pie, cakes ａｎｄ　a lot of other delicious things to eat. But fｏｒthe most part the children enjoy the fun of dressing up ａｎｄ　playing their favorite game of "Trick ｏｒTreat". They run down each street knocking on the doors crying loudly "Trick ｏｒTreat! Money ｏｒeat!", ａｎｄ　most people have some sweets ｏｒmoney ready to give them. Those that do not can expect maybe to have a tyre flattened, ｏｒtheir windows covered in soap. ｏｒthe children may just knock on the doｏｒａｎｄ　run away. Some children think of other people on Halloween. They carry boxes fｏｒUNICEF (The United Nations International Children\'s Emergency Fund). They ask fｏｒmoney to help poｏｒchildren all around the world. Of course, every time they help UNICEF, they usually receive a treat fｏｒthemselves, too. Every autumn, when the vegetables are ready to eat, children pick large orange pumpkins. Then they cut faces in the pumpkins ａｎｄ　put lights inside. It looks like there is a person looking out of the pumpkin! These lights are called jack-o\'-lanterns, which means "Jack of the lantern". But in this modern age many of the pumpkins are being replaced with plastic electric ones that can be brought out each year. Why did Halloween use to be thought the most wonderful night of the year?【单选题】

A.Because people thought at that night witches ａｎｄ　evil spirits came back on earth.

B.Because it was the time fｏｒparties.

C.Because it was an autumn holiday that Americans celebrated every year.

D.Because farmers were allowed to light big fires ａｎｄ　sing songs at that night.

正确答案:A

答案解析:第1段第4句实际是第3句的原因。以前人们把万圣节前夜看成是最好的一夜。在这个夜晚女巫和魔鬼精灵都重返地球。人们保留很多奇异的习俗将这些邪恶的东西赶走。因此选A。
