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 tr

26、eatment of 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

27、. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images. 名师归纳总结 精品学习资料 - - - - - - - - - - - - - - -精心整理归纳 精选学习资料 - - - - - - - - - - - - - - - 第 8 页，共 25 页 - - - - - - - - - Rats are often 30 with spreading disease rather than 31 it, but t

28、his long-tailed animal is highly 32 . Inside a rat s nose are up to 1,000 different types of olfactory receptors (嗅觉感受器 ), whereas humans only have 100 to 200 types. This gives rats the ability to detect 33 smells. As a result, some rats are being put to work to detect TB ( 肺结核). When the rats detec

29、t the smell, they stop and rub their legs to 34 a sample is infected. Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection method doesn t rely on specialist equipment.

31、ad a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information 名师归纳总结 精品学习资料 - - - - - - - - - - - - - - -精心整理归纳 精选学习资料 - - - - - - - - - - - - - - - 第 9 页，共 25 页 - - - - - - - - - is derived. You

32、 may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. Do In-Class Exams Make Students Study Harder? Research suggests they may study more broadly for the unexpected rather than search for answers. A

33、 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 while I am still processing the q

34、uestion. 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 excited when I learned this, f

35、iguring 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 material and guessing my grasp of

36、it, I did some of my own polling 名师归纳总结 精品学习资料 - - - - - - - - - - - - - - -精心整理归纳 精选学习资料 - - - - - - - - - - - - - - - 第 10 页，共 25 页 - - - - - - - - - among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believe

37、s students ultimately learn more and encourages them to form study groups. “ That way they socialize over history outside the class, which wouldn t happen without the pressure of an in-class exam,”he explained, “ Furthermore, in-class exams force students to learn how to perform under pressure, an e

38、ssential work skill. ”D He also says there is less chance of cheating with the in-class variety. In 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 entitled “ Introduction To Congress. ” Some colleges have what they ca

39、ll an “ honor code,” though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn t just call an expert on the subject

40、 matter which I was tackling, or someone who took the class previously, to get me going. E Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school s professors to refrain from take-hone exams. “ Students risk health and well being, as

41、 well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries, ”she told me. 名师归纳总结 精品学习资料 - - - - - - - - - - - - - - -精心整理归纳 精选学习资料 - - - - - - - - - - - - - - - 第 11 页，共 25 页 - - - - - - - - - “ Research now shows that regular quizzes,

42、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 unlikely to be sent home, where one could ask their older brothe

43、rs 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 Broadcast Journalism” at Montgomery Community College in Rockville, Maryland, po

44、ints out that reporting is about investigation rather than the memorization of minute details. “ In my field, it s not what you knowit s what you know how to find out, ” says Koch. “ There is way too much information, and more coming all the time, for anyone to remember. I want my students to search

45、 out the answers to questions by using all the resources available to them. ”G Students test-form preferences vary, too, often depending on the subject and course difficulty. “ I prefer take-home essays because it is then really about the writing, so you have time to edit and do more research,”says

46、Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, “ I find the in-class ones are more stressful in the short term, but there is immediate relief as you 名师归纳总结 精品学习资料 - - - - - - - - - - - - - - -精心整理归纳 精选学习资料 - - - - - - - - - - -

47、 - - - - 第 12 页，共 25 页 - - - - - - - - - swallow information like mad, and then you get to forget it all. 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 sophomore at Emory, says she hardly even

48、considers take-homes true exams. “ If you understand the material and have the ability to articulate (说出) your thoughts, 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 m

49、ake it much harder than it needs to be. And then there those who, not knowing what questions are coming at them, and 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 becau

50、se of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, “ We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in
