Do In-Class Exams Make Students Study Harder?A I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the

11、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 what kind are the most taxing and

12、 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. In fact. 1 was still rewriting my

13、 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 teaches a popular class on U.S.

14、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 wouldn't happen without the pressure of an in-class exam,” he explained. “Furthermore，in-class

15、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 take-home exam for a class entitl

16、ed “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 for two solid days. I

17、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 schools professors to refrain

18、 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 assignments over the course of a t

19、erm 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. Vocational-type classes，such as co

20、mputer 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 investigation rather than t

21、he memorization of minute details. “In my field, its not what you know一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 s by using all the resources available to them.”G Students test-form preferences va

22、ry, too, often depending on the subject and course difficulty. “I prefer lake-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. Then there is the stress factor. Francesca Haass, a senior at M

23、iddlebury, says, “1 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 lead to longer term stress as there is never a moment when the time

24、 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 (說出）your thoughts, they should be a breeze.”H How students ultimately handle tests may depend on their personal test-taking

25、 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 freeze. And then there are we rare folks who fit both those descripti

26、ons.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 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

27、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, “1 like in-class exams because the time is already reserved, as opposed to us

28、ing my free time at home to work on a test,'' lie 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 Better yet，how about what one Hunter College professor report

29、edly 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

30、a slice.注意：此部分試題請在答題卡2上作答。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 more helpful to students.39. In-class exams a

31、re 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 than they actually are.42. The author dropped out of college some forty years ago.43. Some stude

32、nts think take-home exams will eat up their free time.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will cat up their free time.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished sta

33、tements. 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 2with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.That people often experience troub

34、le sleeping in a different bed in unfamiliar surroundings 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

35、. 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 previous work conducted on birds and dolphins that these animals put half of their b

36、rains to sleep at a time so that they can rest while 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 universitys Department of Ps

37、ychological 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, as expected, the participants slept less well on their first night than they did on their second, taking more

38、 than twice as long to fall asleep and sleeping less overall. During deep bleep, 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

39、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 (蜂鳴聲）of the same tone and irregular beeps of a different tone during the ni

40、ght. 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.注意：此部分試題請在答題卡2上作答。46. What did researchers f

41、ind puzzling about the first-night effect?A) To what extent it can trouble people.C) What circumstances may trigger it.B) What role it has played in evolution.D) In what way it can be beneficial.47. What do we learn about Dr. Yuka Sasaki doing her research?A) She found birds and dolphins remain aler

42、t while asleep.B) She found birds and dolphins sleep in much the same way.C) She got some idea from previous studies on birds and dolphins.D) She conducted studies on birds and dolphins' sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A) She monitored the brain act

43、ivity of participants sleeping in a new environment.B) She recruited 35 participants from her Department of Psychological Sciences.C) She studied the differences between the two sides of participants brains.D) She tested her findings about birds and dolphins on human subjects.49. What did Dr. Sasaki

44、 do when re-running her experiment?A) She analyzed the negative effect of irregular tones on brains.B) She recorded participants' adaptation to changed environment.C) She exposed her participants to two different stimuli.D) She compared the responses of different participants."50. What did

45、Dr. Sasaki find about the participants in her experiment?A) They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D) They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 5

46、5 are based on the following passage.Its time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men

47、to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling “very tired” or .exhausted，according to a recent study.This may not be surprising given that this is the age range when women have children. Its also the age range when many women are trying to balance careers and hom

48、e. One reason women may feel exhausted is that they have a hard time saying “no.” Women want to be able to do it all一 volunteer for school parties or cook delicious mealsand so their answer to any request is often “Yes，1 can.”Women struggle to say “no” in the workplace for similar reasons, including

49、 the desire to be liked by their colleagues. Unfortunately, this inability to say “no” may be hurting womens health as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want

50、 to be viewed as aggressive or disruptive at work. For example, theres a problem that needs to be addressed immediately, resulting in a dispute over who should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most，whereas women may approach th

51、e same dispute from the perspective of whats the easiest and quickest way to resolve the problemeven if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wiselyincluding staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.注意：此部分試題請在答題卡2上作答。51. What does the author say is the
