a. it can slow the progression to disability significantly. b. it can reduce relapses rates in patients with relapsing m.s. c. it can decrease the number of brain damages caused by m.s. d. it can make patients excited and ensure patients have a warm feeling. 64. what can you infer from the underlined sentence in the last paragraph? a. bg-12 can relieve the pain from the patients suffering from m.s. b. there is hope but still a long way to find a cure for progressive m.s.c. scientists can not invent medication for patients with progressive m.s.d. patients in the early stages of m.s will still suffer a lot in the future.65. which can be the best title for the text? a. advantages of bg-12 b. good news for the patientsc. comparisons between three drugs d. a new oral medication for the early m.s. 【考点定位】考查句子理解。65.【答案】d【解析】本文是对新发明的一种治疗多发性硬化的口服药物的介绍。【考点定位】考查文章主旨。较难题目特训：科普知识类-9阅读下面短文，掌握其大意，从每题所给的a、b、c、d四个选项中，选出最佳选项，并在答题卡上将该项涂黑。today just as technology changed the face of industry, farms have experienced an “agricultural revolution”. on the farm of today, machines provide almost all the power. one of the most important benefits will be the farm computer. a few forward-looking farmers are already using computers to help them run their farms more efficiently. the computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock (家畜) to buy, when to sell their products, and how much profit they can expect. many computer companies have been developing special computer programs just for farmers. programs are being written for pig producers, grain farmers, potato farmers, and dairy farmers. in the future, farmers will be able to purchase computer programs made to their needs. because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. there can be no doubt that farmers will rely on computers even more in the future. while the old-time farms depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power. another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand”that will be able to move and, in some ways, think like a human being. agricultural engineers believe that computer-aided robots will make shocking changes in farming before the end of the century. unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. scientists are now developing robots that will be able to shear (修剪)sheep, drive tractors, and harvest fruit. even complex jobs will be done by robots. for example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. in the future, this will all be done by robots. in addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. the complete change of the farm is far in the future, but engineers expect that some robots will be used before long. 1. which sentence carried the main idea of the whole passage?

so-called translation glasses transcribe (转录) the translations on a tiny liquid-crystal (液晶) display(lcd)screen. then theres the muscle translator. electrodes capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. the signals are then translated into speech. the electrodes could be replaced with wireless chips implanted in a persons face, according to researchers. during a demonstration held last thursday in cmus pittsburgh campus, a chinese student named sang jun had 11 tiny electrodes attached to the muscles of his cheeks, neck and throat. then he mouthedwithout speaking alouda few words in mandarin (普通话) to the audience. a few seconds later, the phrase was displayed on a computer screen and spoken out by the computer in english and spanish: “let me introduce our new prototype.”this particular gadget (器具), when fully developed, might allow anyone to speak in any number of languages or, as waibel put it, “to switch your mouth to a foreign language”. “the idea behind the universitys prototypes is to creategood enough bridges for cross-cultural exchanges that are becoming more common in the world,”waibel said. with spontaneous (自发的) translators, foreign drivers in germany could listen to traffic warnings on the radio, tourists in china could read all the signs and talk with local people, and leaders of different countries could have secret talks without any interpreters there. 1. which of the following statements is not true? a. a lecture translation can translate what you said into other languages easily. b. muscle translators can translate what you think into speech if you just move your mouth. c. there is no muscle translator in the world now. d. the spontaneous translators will help us a lot. 2. what kind of equipment is not mentioned in this passage? a. lecture translation. b. multiple translator. c. muscle translator. d. translation prototype. 3. whats the final destination of inventing the language translators? a. to make cultural exchanges between different countries easier. b. to help students learn foreign languages more easily. c. to make people live in foreign countries more comfortably. d. to help people learn more foreign languages in the future. 4. what can be inferred from the seventh paragraph? a. the translator is so good that it can translate any language into the very language you need. b. the translator is becoming more and more common in the world as a bridge. c. with the help of the translator, you only need to open your mouth when you want to say something without saying the exact words at all. d. the translator needs to be improved before being put into market. 5. where can this passage probably be excerpted from? a. a newspaper.b. a magazine on science. c. a fairy tale.d. a scientific fantasy book.【参考答案】10.cbadb 阅读理解-djoanne rowling, born on 31 july 1965, is an english fiction writer who writes under the pen name j. k. rowling. rowling is the author of the harry potter fantasy series, which has gained international attention, won multiple awards, and sold over 375 million copies worldwide.jk rowlings new novel arrives with the high drama and state secrecy of a royal birth. its due date is announced in february, and in april the disclosure of its title, the casual vacancy, makes international news. the release of the cover image in july commands headlines again, and fleet street(英国媒体) commissions (委托) a “design guru” to analyze its mysterious artistic beauty, in search of clues as to what might lie within. waterstones(英国连锁书店) predicts the novel will be “the bestselling fiction title this year”. literary critics begin to publish preliminary (初步的) reviews, revealing what they think they will think about a book they have not yet even read. i am required to sign more legal documents than would typically be involved in buying a house before i am allowed to read the casual vacancy, under tight security in the london offices of little, brown. even the publishers have been forbidden to read it, and they give me the manuscript carefully, religiously, as though handling a priceless ming vase. afterwards, i am instructed never to disclose the address of rowlings edinburgh office where the interview will take place. in the 15 years since she published her first harry potter, rowling has become both universally known and almost unrecognizable. the untidy redhair who used to write in the cafes of leith has slowly transformed into a shiny fashionable lady, one who is beyond recognition behind wealth and control. once a penniless single mother, she became the first person on earth to make $1billion by writing books, but her rare public appearances suggested a faint ice maiden quality. rowling is completely relaxed about this arrangement. warm and energetic, quick to laugh, she chatters so freely that her publicist gets nervous and tells her to lower her voice. “am i speaking too loud?” she doesnt look a bit concerned. “well, i cant get passionate and whisper!” when i tell her i loved the book, her arms shoot up in celebration. “oh my god! im so happy! thats so amazing to hear. thank you so much! youve made me incredibly happy. oh my god!” anyone listening would take her for a debut author, meeting her first ever fan. in a way, thats what she is. rowling has written seven harry potter books, and sold more than 450m copies, but her first novel for adults is unlike them in every respect.“obviously i need to be in some form of vehicle to have a decent idea,” she laughs. having dreamed up potter on a train, “this time i was on a plane. and i thought: local election! and i just knew. i had that totally physical response you get to an idea that you know will work. its a rush of adrenaline (肾上腺素), its chemical. i had it with harry potter and i had it with this. so thats how i know.”66.
