17、 treatment of human diseases. Pigeons are often seen as dirty birds and an urban 2 , 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 3 of your index finger, pigeons have a very impressive 4 memory
18、. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images. Rats are often 5 with spreading disease rather than 6 it, but this long-tailed animal is highly 7 . Inside a rat“s nose are up to 1,000 different types of olfactory receptors (嗅觉感受器),
19、 whereas humans only have 100 to 200 types. This gives rats the ability to detect 8 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 9 a sample is infected. Traditionally, a hundred samples would take lab technic
20、ians more than two days to 10 , but for a rat it takes less than 20 minutes. This rat detection method doesn“t rely on specialist equipment. It is also more accuratethe rats are able to find more TB infections and, therefore, save more lives. A. associated B. examine C. indicate D. nuisance E. peak

A. I
22、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 ques
23、tion. 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, fig
24、uring 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 i
25、t, 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 history outside
26、 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 essential work skill.“ D. He also says there is less chance of cheating with the in-class variety. In 2012, 125 students a
27、t 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 around an
28、y 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 matter which I was tackling, or someone who took the class previously, to get me going. E. Following the Harvard scandal,
29、Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school“s professors to refrain from take-home 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 boundaries,
30、“ 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 unlik
31、ely 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“
32、at Montgomery Community College in Rockville, Maryland, points 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 tim
33、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 writi
34、ng, 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 li
35、ke 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 materi
36、al and have the ability to articulate (说出) your thoughts, they should be a breeze.“ H. How students ultimately handle tests 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 are thos
37、e 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 because of my inability to access the information as quickly. A
38、s 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 school.“ J. If nothing else, the situation has given my co
39、llege son and me something to share. When I asked his opinion on this matter, he responded, “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.“ It seems to me that a compromise would be receiving the exam questions a day or two in
40、 advance, and then doing the actual test in class with 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 th
41、e 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.（分数：71.00）(1).Elderly students find it hard to keep up with the rapid changes in education.（分数：7.10）(2).Some believe take-home exams may affect

45、ngs is a phenomenon known as the “first-night“ effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect. Dr. Sasaki knew the first-night effect probably has som
46、ething 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 previous 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
47、remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university“s Department of Psychological Sciences. The participants each slept
48、 in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping l
49、ess overall. During deep sleep, the participants“ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right 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 beeps (蜂鸣声) of the same tone
