Sign has become a scientific hot button.Only in the past 20 years have specialists in language study realized that signed languages are unique-a speech of the hand.They offer new way to probe how the brain generates and understands language and throw new light on an old scientific controversy：Whether language，complete with grammar，is something that we are born with，or whether it is a learned behavior.The current interest in sign language has roots in the pioneering work of one rebel teacher at Gallaudet University in Washington，D.C.，the world's only liberal arts university for deaf people. When Bill Stokoe went to Gallaudet to teach English，the school enrolled him in a course in signing.But Stokoe noticed something odd：among themselves，students signed differently from his classroom teacher.Stokoe had been taught a sort of gestural code，each movement of the hands representing a word in English.At the time，American Sign Language（ASL）was thought to be no more than a form of pidgin English（混杂英语）.But Stokoe believed the "hand talk" his students used looked richer.He wondered：Might deaf people actually have a genuine language？And could that language be unlike any other on Earth？It was 1955，when even deaf people considered their signing as "substandard".Stokoe's idea was academic heresy（异端邪说）. It is 37 years later.Stokoe--now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture-is having lunch at a cafe near the Gallaudet campus and explaining how he started.a revolution For decades educators fought his idea that signed languages are natural languages like English，French and Japanese.They assumed language must be based on speech，the modulation（调节） of sound.But sign language is based on the movement of hands，the modulation of space. "What I said，" Stokoe explains， "is that language is not mouth stuff--it's brain stuff."（1）The present growing interest in sign language was encouraged to develop by ____ .A.a famous scholar in the study of the human brainB.a leading specialist in the study of liberal artsC.an English teacher in a university for the deafD.some senior experts in American Sign Language（2）According to Stokoe，sign language is ____ .A.a substandard languageB.a genuine languageC.an artificial languageD.an international language（3）Most educators objected to Stokoe's idea because they thought ____ .A.sign language was not extensively used even by deaf peopleB.sign language was too artificial to be widely acceptedC.a language should be easy to use and understandD.a language could only exist in the form of speech sounds

In many countries in the process of industrialization, overcrowded cities present a major problem. Poor conditions in these cities, such as lack of housing, inadequate sanitation(卫生)and lack of employment, bring about an increase in poverty, disease and crime. The over-population of towns is mainly caused by the drift of large numbers of people from the rural areas. These people have become dissatisfied with the traditional life of farming, and have come to the towns hoping for better work and pay. One possible solution to the problem would be to impose registration on town residents. Only officially registered residents would be allowed to live in the towns and the urban population would thus be limited. In practice, however, registration would be very difficult to enforce (推行); it would cause a great deal of resentment (不满), which would ultimately lead to violence. The only long-term solution is to make life in the rural areas more attractive, which would encourage people to stay there. This could be achieved by providing encouragement for people to go and work in the villages. Facilities in the rural areas, such as transport, health and education services should be improved. Education should include training in improved methods of farming and other rural industries, so as to develop a more positive attitude towards rural life. The improvement of life in the villages is very important, because the towns themselves cannot be developed without the simultaneous or previous development of the rural area.What does the word" urban" (Line 2, Para. 3)mean A. Of the city.B. Out of work.C. In a bad condition.D. Of enormous size.

When you#39;ve read the same paragraph 10 times and you still make little of it as you are reading ancient Egyptian, and you#39;re not studying ancient Egyptian, it#39;s time for you to put the books down. Experts say good breaks are a critical part of exam preparation and actually make your brain work better. Debbie Bruckner, the director of the Student Union Wellness Centre at the University of Calgary, says an overburdened brain stops processing new information.quot;You#39;ve got to put it into your short-term memory and then move it into your long-term memory,quot; she says. To do that, you need to stop cramming new knowledge into your head. Psychologist Joanne Mills says most people can concentrate for 45 minutes to an hour at a time, but then need 15 minutes to rest. She suggests picking your break activity -- taking a walk, listening to music -- and setting a timer for 15 minutes. quot;It#39;s a cue to your mindquot; she says. Mills also suggests setting targets and stopping when you#39;ve reached them.quot; Some students will take that break even if they haven#39;t finished what they set out to do and then they don#39;t really relax or enjoy it because their mind is racing with #39; I must, I should, I have to.#39; “If you#39;re in the flow, ride the momentum until you come to a natural break in the material,then set the timer again and walk to the corner store. Alternating which books you#39;re hitting also helps. Work on English for an hour, then switch to math. It#39;s like exercising multiple muscles at the gym, as different parts of your brain work for different subjects. Bruckner says that to maintain a healthy mind-body-spirit temperament in the heat of exam season, sit down with your calendar. quot;Make a schedule for a month -- when your assignments are due, when your final exams are, what the weighting is for each,quot; she says.1.[单选题]By saying quot; what the weighting is for eachquot; the author means that you will know_____.A.which exam is the most importantB.what time each exam isC.how to balance your timeD.what is the most important task each time2.[单选题]According to Debbie Bruckner, to learn new knowledge well_____.A.you need to stop learning new informationB.you need to process it as quick as possibleC.you should put it into your long-term memoryD.you don#39;t need to put it into your short-term memory3.[单选题]The word quot;cramquot; in the second paragraph isclosest in meaning to_____.A.put something into a container, especially in a hurryB..put many things into a place at one time that makes itcompletely fullC.teach students as much as possible in a short time beforethe examinationD.put too much knowledge into the brain, although there ishardly enough room for it4.[单选题]The author uses quot;ancient Egyptianquot; to infer to that the reading is_____.A.very interestingB.hard to understandC.very boringD.of different culture5.[单选题] If you haven#39;t finished the target you set, youshould_____.A.still take the break in every 45 minutesB.wait until you come to a natural break in the materialC.set the timer again and walk to the corner storeD.stop thinking quot;I must, I should, I have toquot;
