You may not use any of the words in the bank more than once.A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some 26 skills that could help the treatment o

23、f human diseases.Pigeons are often seen as dirty birds and an urban 27 , but they are just the latest in a long line of animals that have been found to have abilities to help humans. Despite having a brain no bigger than the 28 of your index finger, pigeons have a very impressive 29_ memory. Recentl

24、y it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but this long-tailed animal is highly 32 .Inside a rats nose are up to 1,000 different types of olfactory receptors (嗅覺(jué)感受器),whereas h

25、umans only have 100to 200 types. This gives rats the ability to detect _33 smells. As a result, some rats are being put to work to detect TB肺結(jié)核).When the rats detectthe smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more tha

29、ather than search for answers.A I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer wh

30、ile I am still processing the question.B Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was

31、excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.C As I was suffering through my week of anxiety, overthinking the mater

32、ial and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups.“That way they s

33、ocialize over history outside the class, which wouldnhappen without the pressure of an inclass exam, he explained,“ Furthermore, -class exams force students to learn how to perform under pressure, and essential work skill.”D He also says there is less chance of cheating with the in-class variety. In

34、 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitleda Introduction To Congress. Some colleges have what they call ancode, though if you are smart enough to get into these schools, you are either smart enough to ge

35、t around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, Imomentarily wondered if I couldn t just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going.E Following the Harvard s

36、candal, Mary Miller, the former dean ofstudents at Yale, made an impassioned appeal to her school s professorsrefrain from take-hone exams. a Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-homeexams without clear, time-limited boundari

37、es, she told me. a Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention.”F Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unli

38、kely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches“ History of BroadcastJournalism “

39、 at Montgomery Community College in Rockville, Maryland,歡迎下載9points out that reporting is about investigation rather than the memorizationof minute details.In my field, it s not what you know it s what yG Studentshow to find out, says Koch. “There is way too much information, and more coming all the

40、 time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them.tform preferences vary, too, often depending on thesubject and course difficulty.-Hcpnefeissays because it is thenreally about the writing, so you have time to edit a

41、nd do more research, says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says,-cla ssIcfrnes threinmore stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all

42、. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up. Meanwhile, Olivia Rubin, a sophomor Emory, says she hardly even considers takehomes true exams. If you understand the material and have the ability to articulate 說(shuō)出）yourtho

43、ughts, they should be a breeze.H How students ultimately handle stress may depend on their personal test-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there those who, not knowing what questions are coming at them, and

44、 having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions.I Yes, my advanced age must factor into the equation 等式），in part because of my inability toaccess the information as quickly. As another returning student at Columbia, Kate Marber, toldme,

45、“Ware learning not only all this information, but essentially how to learn again. Ourfellow students have just come out of high school. A lot has changed since we were last inschool. ”J If nothing else, the situation has given my college son and me something to share, When Iasked his opinion on this

46、 matter, he responded,-cla ss lexamsbecause the time isalready reserved, as opposed to using my free time at home to work on a test, he responded.It seems to me that a compromise would be receiving the exam questions a day or two inadvance, and then doing the actual test in class the ticking clock o

47、verhead.K Better yet, how about what one Hunter College professor reportedly did recently for her finalexam: She encouraged the class not to stress or even study, promising that, “It is going to be apiece of cake.there was not a blueWhen the students came in, sharpened pencils in hand,book in sight.

48、 Rather, they saw a large chocolate cake and they each were given a slice.36. Elderly students find it hard to keep up with the rapid changes in education.37. Some believe take-home exams may affect students performance in other courses.38. Certain professors believe in-class exams are ultimately mo

49、re helpful to students.39. In-class exams are believed to discourage cheating in exams.40. The author was happy to learn she could do some exams at home.41. Students who put off their work until the last moment often find the exams more difficult thanthey actually are.42. Different students may pref

50、er different types of exams.43. Most professors agree whether to give an in-class or a take-home exam depends on type ofcourse being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.Section CDirections: There are 2

51、passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQ

52、uestions 46 and 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the -night effect If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her col

53、leagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from prev

54、ious work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (甫食者).This led her to wonderif people might be doing the same thing. To take a closer look, her team studied 35 healthy peopl

55、e as they slept in the unfamiliar environment of the university s Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, asexpected, the participant

56、s slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the paticipants brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres 伴球)of their b

57、rains did not sleep nearly as deeply as theirright hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed bee

58、ps (蜂鳴聲)of the same tone and irregular beeps of adifferent tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. What did researchers find puzzling about the first-night effect?A) To what extent it can tro
