1、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 forpeople. 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 forpaying 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 forthe same amount of time.So, even going fora walk every 2 or3 days forjust 10 to 45 minutes can help. That should be good news forthe 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 fora walk orrun around with friends. Whatever you do, though, don\'t try to read and walk at the same time. You could end up hurting yourself!After taking exercise fora few weeks, the mice were found to have ______.【单选题】
A.higher blood pressure
B.faster heartbeat
C.more blood flow to the brain
D.better appearance
正确答案:C
答案解析:本题难度不大,找到答案依据不难。答案依据在文章第三段。带着题干信息词回到文章定位。第三段第二句谈到运动老鼠大脑中的血液流量大于不运动的,回来看选项,很明显,C是近义解释,是答案。
2、Dung to DeathFields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant "superbugs". The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.Some 20,000 tons of antibiotics are used in the European unionand the US each year. More than half are given to farm-animals to prevent disease and promote growth. But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people. Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end. up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute forEnvironmental Science and Technology in Dubendorf. and manure contains especiaily high levels of bugs that are resistant to antibiotics he says.With millions of tons of animals manure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route forspreading resistance, he said. The drugs contaminate the crops, which are then eaten. ______Mueller is particularly concerned about agroupof antibiotics called sulphonamides. They do not easily degrade ordissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously. There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged and are not broken down by conventional sewage treatment.【单选题】
A.They do not easily degrade ordissolve in water.
B.and manure contains especiaily high levels of bugs that are resistant to antibiotics he says.
C.Animal antibiotics is still an area to which insufficient attention has been paid
D.But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.
E.His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.
F.They could also be leaching into tap water pumped from rocks beneath fertilized fields.
正确答案:F
答案解析:选项F中的also 一词说明前面应讲到过一个类似的内容。这句讲的是这些药物可能从施过肥料的农田下面的岩石沥滤到自来水里去;前面一句讲的是受到这些药物污染的谷物被人食用,这两句讲的都是这些药物如何对人类造成威胁。
3、Science Fiction1 Amongst the most popular books being written today are those that are usually classified asscience fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories. 2 It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some forms of ideal society, a theme that is still often found in modern stories. 3 Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verve and H. G Wells, to mention just two well known authors, have been translated into many languages. 4 Modern science fiction writers don\'t write about men from Mars orspace adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; orin imagining future worlds that are a reflection of the world that we live in now. Because of this their writing has obvious political undertones (涵义). 5 In an age where science fact frequently overtakes (超过) science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology. Paragraph 2____【单选题】
A.A Fairly New Development
B.Classics of Science Fiction
C.Difficulty in Keeping ahead of Scientific Advances
D.Origins of Science Fiction
E.Themes of Modern Science Fiction
F.SuccessfulFilms
正确答案:D
答案解析:第2段第1句说科幻小说常被认为是文学中较新的一种事物,但它的先驱可以在几百年以前写的书中找到。连词but在这里起转折作用。这一句的中心词是ancestors,与origin意思相似,根据这一线索,我们得知该段是在介绍科幻小说的起源,故选D。
4、The Value of AdvertisementMoney spent on advertising is worth spending. It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and making it possible to provide forexport at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need forlabor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus orsubway would cost more. and perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people fora little while through misleading advertising. He will not do so forlong, forthe public has the good sense not to buy the poorgoods more than once. If you see a product frequently advertised, it is the proof I know that the product does what is promised forit, and that it has good value. Advertising does more forthe good of the public than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its messages were nothing but information, that would be difficult to get more people to buy, foreven the choice of the colorof a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.What is the meaning of "touch on" in Paragraph 4?【单选题】
A.Feel slightly.
B.Strike gently.
C.Write quickly.
D.Mention briefly.
正确答案:D
答案解析:前3段讲了广告好处,第4段提到了广告的说服作用和告知作用,但仅是提到而已没有展开讲解,因此选D。
5、Seeing Red Means Danger AheadThe colorred often means danger and by paying attention, accidents can be prevented. In the future, the colorred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports orother kinds of materials could one day contain a colorswitching material. It will turn red before a structure collapses orfalls apart. The secret behind the colorswitching material is a particular type of molecule. A molecule is agroupof atoms held together by chemical bonds. Molecules come at all shapes and sizes, and make up everything. You can see, touch orfeel. How a molecule behaves depends on what kinds of atoms it contains, and how they\'re held together. When a polymer (聚合物) containing a colorswitching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" orweak, one of the mechanophore bonds breaks and the material turns red. "It\'s a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the colorswitching polymers in their lab. The test results proved encouraging. There is a way to get rid of the colorlight when a bright light is shone on the mechanophore. The broken bond is fixed and the red colordisappears. This "self-healing" may be a problem forengineers. They need to use the colorchanger in big construction projects that will be outside in sunlight. and sunlight will make the mechanophore\'s warming system useless. Sottos and her fellow scientists still have ______ work to do before the colorswitching molecules can be used outside the lab. 【单选题】
A.a part of
B.a type of
C.a lot of
D.a part of
正确答案:C
答案解析:意思应该是在变色分子可用于实践之前,Sottos和她的团队还需要做很多的努力。所以选a lot of合适。
