23、.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. Recently it was shown t
24、hat 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（嗅觉感受器）, whereas humans only have
25、 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 detect 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 t
26、o 35 , but for a rat it takes less than 20 minutes. This rat detection method doesnt rely on specialist equipment. It is also more accuratethe rats are able to find more TB infections and, therefore, save more lives.A) associatedI) slightB) examineJ) specifyC) indicateK) superiorD) nuisanceL) suspic

28、s derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the question 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
29、 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 while I am still proces
30、sing 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 excited when I learne
31、d 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 material and guessing my g
32、rasp 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 socialize over histor
33、y outside the class, which wouldnt happen without the pressure of an in-class exam,” he explained, “Furthermore, in-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 2012, 125 stu
34、dents 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 call an “honor code,” though if you are smart enough to get into these schools, you are either smart enough to get ar
35、ound 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 couldnt 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 scand
36、al, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her schools professors to refrain from take-hone exams. “Students risk health and well-being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundari
37、es,” she told me. “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 unl
38、ikely 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 Broadcast Journalism
39、” at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. “In my field, its not what you knowits what you know how to find out,” says Koch. “There is way too much information, and more coming all the tim
40、e, for anyone to remember. I want my students to search 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,
41、 so you have time to edit and do more research,” says 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 swallow information like
42、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 considers take-homes true exams. “If you understand the material
43、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 make it much harder than it needs to be. And then there those who, n
44、ot 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 because of my inability to access the information as quickly. As another
45、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 school.”J If nothing else, the situation has given my college son an
46、d me something to share, When I asked his opinion on this matter, “I like in-class exams because the time is already 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 in advance, an
47、d then doing the actual test in class the ticking clock overhead.K Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, “It is going to be a piece of cake.” When the students came in, sharpened pencils in hand, there was not a blue book in sight. 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 perfo
