1、Meet Your Memory1. Memory is something that cannot be seen, touched or weighed. It is thought to be abstract. It is a set of skills rather than an object. Neither is there a single standard for judging a good or poor memory. 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), or grouping 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 for it. 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 order it 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。
2、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, or the Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged or destroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbor if they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.Depending on where they occur, hurricanes have ______.【单选题】
A.different labels
B.window and glass doors
C.inland flooding
D.early warning
E.natural disaster
F.a constant speed
正确答案:A
答案解析:本题难度不大,答案依据比较明显,在文章第二段的第一句:Hurricanes are given a different label,depending on where they occur.回来看选项,A项符合原文句意,是答案。
3、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, for no obvious gain.Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines(疫苗). So once again there\'s a good reason to the virus, just in keep 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 _____ 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.for
B.in
C.on
D.with
正确答案:D
答案解析:本题有一定难度,考查介词with的用法,干扰项有一定的干扰。with support,固定搭配,指“在……帮助下”,此处指“在国际社会帮助下”,原句比较好的理解语序是:Keep the virus in a well - guarded UN laboratory with international support…,答案要根据介词的基本含义和用法来判断,答案是D。
4、Cloning: Future Perfect?1 A clone is an exact copy of a plant or animal produced from any one cell. Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997, research into cloning has grown rapidly. In May 1998, scientists in Massachusetts managed to create two identical calves using cloning technology. A mouse has also been cloned successfully. But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement: "We will have managed to clone a human being within the next two years," he told the world. 2 Seed\'s announcement provoked a lot of media attention, most of it negative. In Europe, nineteen nations have already signed an agreement banning human cloning and in the US the President announced: "We will be introducing a law to ban human cloning and many states in the US will have passed anti-cloning laws by the end of the year". 3 Many researchers are not so negative about cloning. They are worried that laws banning human cloning will threaten important research. In March, The New England Journal of Medicine called any plan to ban research on cloning humans seriously mistaken. Many researchers also believe that in spite of attempts to ban it, human cloning will have become routine by 2010 because it is impossible to stop the progress of science. 4 Is there reason to fear that cloning will lead to a nightmare world? The public has been bombarded (轰炸) with newspaper articles, television shows and films, as well as cartoons. Such information is often misleading, and makes people wonder what on earth the scientists will be doing next. 5 Within the next five to ten years scientists will probably have found a way of cloning humans. It could be that pretty soon we will be able to choose the person that we want our child to look like. But how would it feel to be a clone among hundreds, the anti-cloners ask Pretty cool, answer the pro-cloners (赞成克隆的人). Richard Seed\'s announcement received ____. 【单选题】
A.the nucleus of a cell
B.cloned human beings
C.a human being in two years
D.a law to ban human cloning
E.a report on human cloning
F.heavy media coverage
正确答案:F
答案解析:文章第2段谈到Seed的言论引起了激烈的反应,故选F。
5、The Book of LifeSo far, scientists have named about 1.6 million living species, and that\'s a just a fraction of that probably exists on Earth. With so many plants, animals and other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.To get the encyclopedia started, the creators will use information from scientific databases that already exist. And eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, for example, will be able to input which bird they\'ve seen and where. The technology for this kind of tool has only become available.As the EOL develops, you might find it useful for school projects. The site will feature special pages for kids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven\'t been reviewed.Another convenient feature of the EOL is that you\'ll be able to pick the level of detail you want to see to match your interest, age and knowledge. If you wanted to learn about bears for a science class report, for example, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature and exploration of bears.It now takes years for scientist to collect all the data they need to describe and analyze species. The creator of the Encyclopedia of Life hope that their new tool will speed up that process."Spider" and "bird" mentioned in Paragraph 1 are examples to illustrate ______.【单选题】
A.there are numerous living species on Earth
B.animals are people\'s friends
C.it is easy to see spiders and birds
D.here are many types of spiders and birds
正确答案:A
答案解析:本题有一定难度,带着题干信息词回文章定位,答案依据主要在文章第一段:So far, scientists have named about l.6 million living species, ...it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.谈到了地球物种数量巨大,回来看选项,A项和原文句意相近,是答案。
6、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 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 ______. 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.count
B.amount
C.digit
D.rate
正确答案:D
答案解析:直接借助空白所在的局部搭配(事故……)判断答案是D(事故发生率)。

8、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 for blind people in Sommerset and a resource centre for the 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 door without 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 or falling frequencies to indicate whether people should go up or down 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。
9、English and English Community1 There is no doubt that English is a useful language. The people who speak English today make up the largest speech community in the world with the exception of speakers of Chinese. 2 A speech community is similar to other kinds of communities. The people who make up the community share a common language. Often they live side by side, as they do in a neighborhood, a village, or a city. More often they form a whole country. National boundaries, however, are not always the same as the boundaries of a speech community. A speech community is any group of people who speak the same language no matter where they happen to live. 3 We may say that anyone who speaks English belongs to the English speech community. For convenience, we may divide the speakers into two groups: one in which the speakers use English as their native language, the other in which the speakers learn English as a second language for the purpose of education, commerce, and so on. 4 Learning a second language extends one\'s vision and expands the mind. The history and literature of a second language record the real and fictional lives of people and their culture; a knowledge of them adds to our ability to understand and to feel as they feel. Learning English as asecond language provides another means of communication through which the window of the entire English speech community becomes a part of our heritage. Many people learn English as____. 【单选题】
A.a second language
B.the same language
C.the same speech community
D.any other language
E.national boundaries
F.a part ofone\'s heritage
正确答案:A
答案解析:从文章第2段可以推断,许多人将英语作为第二语言来学。
