2021年12月英语四级考试仔细阅读答案及解析(1)
解析:
57、选择 encourage boys to express their emotions more freely
58、选择 perform relatively better
本题较难,题干问通常大家都认为在男女同校的学校中男生都怎样。
原文四段末句中received wisdom表示常识或者被多数人所接受的观点,于是后面的部分是本题的出题点。
59、选择 it fails to give boys the attention they need
原文红字处说这些体制都更关心女生,取反之后意为这些体制都没那么关心男生,于是与此选项对应。
60、选择teaching can be tailored to suit the characteristics of boys
原文红字说在男校里,老师可以"根据男生的学习风格量身定制(tailor)课程"
61、选择 they conform to stereotype
文章最后两段都是在总结人们对男生的一般印象以及男校如何避免一些问题的出现,James的实验提及许多男生都正遵循着老套的路线发展,即本选项的同义改写;其余选项均是例举中的具体内容,
包含于此答案。

2021年12月大学英语四级考试阅读理解真题及答案详解(全套)

2021年12月大学英语四级考试阅读理解真题及答案(全套)——幸福就好我亦安2021年12月大学英语四级考试阅读理解真题(一)【阅读】Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. 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 2 with a single line through the centre.Passage OneQuestions 56 to 60 are based on the following passage.In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Evensimple visual cues, like plate size and lighting, have been shown to affect portion size and consumption.A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they’d eaten but rather by how much food they'd seen in front of them —in other words, how much they remembered eating.This disparity (盖弃)suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal, says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol."Hunger isn't controlled solely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal," Brunstrom says. "This shows that the relationship between hunger and food intake is more complex than we thought."These findings echo earlier research that suggests our perception of food can sometimes trick our body’s response to the food itself. In a 2021 study, for instance, people who drank the same 3S0-calorie (卡路里)milkshake on two separate occasions produced different levels of hunger-related hormones (荷尔蒙),depending on whether the shake’s label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less, the new findings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.The so-called mindful-eating strategies can fight distractions and help us control our appetite, Brunstrom says.注意:此部份试题请在答题卡2上作答。

Even people who think they are sleeping enoughwould probably be better off with more rest.The beginning of our sleep-deficit (睡眠不足) crisis can betraced to the invention of the light bulb a century ago. From diary entries andother personal accounts from the 18th and 19th centuries, sleep scientists havereached the conclusion that the average person used to sleep about 9.5 hours anight. “The best sleep habits once were forced on us, when we had nothing to doin the evening down on the farm, and it was dark.” By the 1950s and 1960s, thatsleep schedule had been reduced dramatically, to between 7.5 and eight hours,and most people had to wake to an alarm clock. “People cheat on their sleep,and they don't even realize they're doing it,” says Dr. David. "They thinkthey're okay because they can get by on 6.5hours, when they really need 7.5, eight or even more to feelideallyvigorous."Perhaps the most merciless robber of sleep,researchers say, is the complexity of the day. Whenever pressures from work,family, friends and community mount, many people consider sleep the leastexpensive item on his programme. 'In our society, you're considered dynamic ifyou say you only need 5.5 hours' sleep. If you've got to get 8.5 hours, peoplethink you lack drive and ambition."To determine the consequences of sleep deficit,researchers have put subjects through a set of psychological and performancetests requiring them, for instance, to add columns of numbers or recall apassage read to them only minutes earlier. "We've found that if you're insleep deficit, performance suffers," says Dr. David. “Short-term memory isweakened, as are abilities to make decisions and to concentrate.”1. People in the 18th and 19th centuries used to sleep about 9.5 hoursa night because theyhad _______ .A) no drive and ambition B) noelectric lightingC) the best sleep habits D)nothing to do in the evening2.

2021年12月英语四级阅读真题及答案 第1套 段落匹配 (2)

2021年12月英语四级阅读真题及答案第1套段落匹配Directions: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. Answer the questions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System?[A]Any product that promises to protect your home deserves careful examination. So it isn’t surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in 2021.The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technicalmeans to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?[D]Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in thelistener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling. They will, however, need so know what system they’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we’re talking about a highly targeted, semi-sophisticated attack, and not the sort forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert(推送警报).From there, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference toour test lab, we tested the attack out for ourselves, and were able to verify that it’s possible with the right equipment. However, we also verified that SimpliSafe’s anti-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of successful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it thatsomeone will successfully jam their way into your home and steal your stuff?[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includescommon sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessary equipment and skill.37. Interfering with a wireless security system is similar to interfering with a conversation.38. A burglar has to continuously jam the wireless security device to avoid triggering the alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguish incidental radio interference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate the alarm once something wrong is detected.43. Different measures should be taken to protect one’s home from burglary in addition to the wireless security system.44. SimpliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequency by Internet search.36. [I]37. [D]38. [J]39. [F]40. [B]41. [H]42. [C]43. [K]44. [G]45. [E]。

whatever office cliche you employ to depict it, we"ve all been in that situation where wefeel like we might be swallowed up by our workload、Noheless many a way may be used to manage your to-do list to prevent feeling overwhelmed、 How to make peace with your workload once and for all goes as follows、[B] Get organized、“Clear the deadwood out of your desk and keep your office in shape, which enhances your capability to handle other tasks and raises the probability that you’ll retrieve the items you do needin a faster and easier fashion,” says Jeff Davidson who works as a work/life expert and writer of more than50 books on workplace issues、“When something can be disposed, let it go, given in reality most of what you retain is replaceable、” Joel Rudy, vice president of operations for Photographic Solutions, with better than thirty years of business management experience, believes that keeping organized is a must、“ Messy work areas are nonproductive in some measure、 Provided that you can"t locate a document or report easily because it’s lost in a pile of mess, then you have a problematic situation,” he says、“Thereby you a re supposed to take the time to tidy up your work areas and keep yourimportant files, manuals and reports in an accessible location, which will maximize your efficiencies、”[C] Make a to-do list, then cover it up、 It may sound weird, but it works, says Jessica Carlson, an account executive at Bluefish Design Studio which is an advertising consulting firm、 Carlson urges her team to utilize to-do lists to stay on track and highlight items that are a priority、“Cover up the list, with the exception of one high-priority task at one time,” she suggests、“This will allow you to focus better on the task at hand; otherwise, it will be easy to get overwhelmed if you’re reading through a to-do list that spans an entire page、 Concentrating on a single itemwill make y our tasks appear like they are more doable,” Carlson says、[D] Stop multitasking、 Despite what you may consider multitasking, it’s counterproductive、Unless you’re drinking coffee while scanning your morning e-mails, you’re not saving any time by attemptin g to do ten things at once、“If you find yourself getting tangledin too many things, it may be of much necessity of you to re-evaluate your involvement,” Rudy says、“Your mindwill wander from one topic to another and you may end up never acplishing a thing、” Rudy remends the best way to stop multitasking is to create priority lists with deadlines、“When applicable, plete one project before you move further on to the next one,” he says、[E ] Set time limits、 Deborah Chaddock-Brown, awork-at-home single pa rent, says she’s frequently overwhelmed by the demands of maintaining order in her residence and running her own business、 Still, she manages to “do it all” by setting a time limit for each task、“I have the type of personality that flits (轻轻地掠过)from thing to thing because I do have so much on my plate,” Brown says、“As a consequence I assign time slots: For the next15 minutes I will participate insocial media for the purpose of marketing my business (not sending photos or playing Farmville)and that is the only thing I am about to do for the next15 minutes、 When the time is up, I move on to the next task、That way, at night I don’t end up with apile of tasks to acplish even though I felt busy all day、”[F ] Talk to your manager、“Quite often, people are working on things that are no longer a top priority, but someone forgot to tell them (that they’re no longer important)、 There are usually clear priorities in the manager’s head; he or she has just not done a great job municating those with the employee,” s ays Holly Green, CEO of The Human Factor、Green’s suggestion unfolds in this manner: “If you find yourself confronted with too many responsibilities, sit down, note the significant things you are in charge of, and go to your manager to have a conversation to discuss priorities, trade-offs, time mitments and interdependencies required to do each thing well, and then ask what you should stop working on or work on less so you can get the right things done、” Green says managers should be willing to help sort out priorities, so long as employees have a can-do approach and aren’t just plaining about their workload、[G ] Eliminate time wasters、“If interruptions are keeping you from your responsibilities, learn how to deal with them accordingly,” says Eileen Roth, author of Organizing for Dummies、 Roth proposes the following suggestions to bat disruptions: “Use voice mail to cutdown on telephone interruptions, turn off the alert that says ‘You’ve got an e-mail; and give staff members a set time to visit you、” Justi n Gramm, president of Globella Buyers Realty, exemplifies Roth’s point、“E-mail had been a big time waster for me in the past because it was a constant interruption, causing me to lose focus on the task at hand,” he says、 Since determined to check his e-mails only twice a day, Gramm says he has bee much more efficient、“If people want to get more work done, they need to stop checking e-mails and get down to business,” he says、[H] Assess your workload before taking on new tasks、“The paradox of today’s work environment is that the more you do, the more that’s expected of you,” Davidson says、 In order to better assess your workload, Davidson suggests asking yourself the following questions before agreeing to undertake new responsibilities: Is the task aligned (使一致)with your priorities and goals; Are you likely to be as prone to saying yes to such a request tomorrow or next week; What else could you do that would be more rewarding; What other pressing tasks and responsibilities are you likely to face; Does the otherparty have options other than you; Will he or she be crushed if you say no?[I] Want to know more? Most of our experts remended books for additional tips on how to maximize efficiency, but one book was mentioned time and again、 Check out The Seven Habits of Highly Effective People、46、“The more you do, the more you are expected to do” has been a paradox in today’s work environment、47、 As long as employees have a can-do attitude and do not just plain about their workload, the managers would like to help them decide what to do first、48、 As a single parent, Deborah Chaddock-Brown finds it difficult to make a balance between business and housework、49、 There are many useful methods of preventing people from feeling overwhelmed by workload、50、 Messy work areas are nonproductive to some extent, so you are supposed to keep your work areas tidy and important files at hand、51、To know more about how to maximize efficiency, The Seven Habits of Highly Effective People is remended、52、 In Organizing for Dummies, using voice mail to cut down on telephone interruptions and turning off thee-mail notice are suggested in bating interruptions、53、 According to Rudy, the best way to stop multitasking is to make a list of priorities and set deadlines for each task、54、 Focusing on a single matter will make your tasks appear more possible to be done、55、 In fact, most of what people retain is substitutable, so dispose the things that are disposable、答案与解析Section B46、[H]。
