Part Reading Comprehension(40 minutes) Section ADirections: In this section, there is a passage with ten blanks. You are required to select one word for each bla
21、nk from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may
22、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 some26skills that could help the treatment of human diseases.Pigeons are often seen as dirty birds and an urban27 , but they are just the lates
23、t in a longline of animals that have been found to have abilities to help humans. Despite having a brain no bigger than the28of your index finger, pigeons have a very impressive29memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images
24、.Rats are often30with spreading disease rather than31it, but this long-tailed animal is highly32. Inside a rats 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
25、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 to 35 , but for a rat it takes less than 20 minutes. This rat detection method doesnt rely on s
26、pecialist equipment. It is also more accurate the rats are able to find more TB infections and, therefore, save more lives.A) associatedI) slightB) examineJ) specifyC) indicateK) superiorD) nuisanceL) suspiciousE) peakM) tipF) preventingN) treatedG) prohibitingO) visualH) sensitiveSection BDirection
27、s: In this section, you are going to read 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 is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter.
28、 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)I have always been a poor test-taker. So it may seem rather strange that I have r
29、eturned 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 question.B)Since there is no way for me to avoid exams, I am currently questioning
30、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, figuring I had a full week to do the research, read the texts, and write it all up.
31、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 it, I did some of my own polling among students and professors. David Eisenbach, who
32、 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 the class, which wouldnt happen without the pressure of an in-class exam,” he expl
33、ained. “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 at Harvard were caught up in a scandal when it was discovered they had cheated on a tak
34、e-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 any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless
35、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 scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her schoo
36、ls 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,” she told me. “Research now shows that regular quizzes, short essays, and other assignmen
37、ts 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 brothers and sisters to help. Vocationa
38、l-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, points out that reporting is about i
39、nvestigation rather than the memorization of minute details. “In my field, its not what you know its 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 out the answers to questions by using
40、 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 Elizabeth Dresser, a junior at Barnard.
41、 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 mad, and then you get to forget it all. Take-homes require thoughtful engagement which can le
42、ad 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 and have the ability to articulate (说出) your thoughts, they should be a breeze.”H)How student
43、s 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 those who, not knowing what questions are coming at them, and having no resources to refer to, can fre
44、eze. 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, told me, “We are learning not only all this inf
45、ormation, 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 and me something to share. When I asked his opinion on this matter, he responded, “I like in-
46、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, and then doing the actual test in class with the ticking clock overhead.K)Bette
47、r 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 performance in other courses.38.Certain professors believe in-cl
