Each statement contains information given in one of the paragraphs. Identify the corresponding letter to the paragraph from which the information is derived. You may choose a paragraph more than once.The Peak Time For EverythingA)Could you pack more into each day if you did everything at the optimal time? A growing body of research suggests that paying attention to the body clock, and its effects on energy and alertness, can help pinpoint the different times of day when most of us perform our best at specific ta sks, from resolving conflicts to thinking creatively.1. Keep pace with natural rhythms.B) Most people organize their time around everything but the body's natural rhythms. Workday demands, commuting, social events and kids' schedules frequently dominate -- inevitably clashing with the body's circadian(生理节奏的) rhythms of waking and sleeping.C)Disruption of circadian rhythms has been linked to such problems as diabetes, depression, dementia(痴呆)and obesity, says Steve Kay, a professor of molecular and computational biology at the University of Southern California. When the body's master clock can synchronize functioning of all its metabolic(新陈代谢的), cardiovascular and behavioral rhythms in response to light and other natural stimuli, it 'gives us an edge in daily life,' Dr. Kay says.D)When it comes to doing cognitive work, for example, most adults perform best in the late morning, says Dr. Kay. As body temperature starts to rise just before awakening in the morning and continues to increase through midday, working memory, alertness and concentration gradually improve. Taking a warm morning shower can jump-start the process. E)The ability to focus and concentrate typically starts toslide soon thereafter. Most people are more easily distracted from noon to 4 p.m., according to recent research led by Robert Matchock, an associate professor of psychology at Pennsylvania State University. Alertness tends to slump after eating a meal, Dr. Matchock found. Sleepiness also tends to peak around 2 p.m., making that a good time for a nap, says Martin Moore-Ede, chairman and chief executive of Circadian,a Stoneham, Mass., training and consulting firm.2. Make good use of fatigue.F) Surprisingly, fatigue may boost creative powers. For most adults, problems that require open-ended thinking are often best tackled in the evening when they are tired, according to a 2011 study in the journal Thinking & Reasoning. When 428 students were asked to solve a series of two types of problems, requiring either analytical or novel thinking, their performance on the second type was best at non-peak times of day when they were tired, according to the study led by Mareike Wieth, an assistant professor of psychological sciences at Albion College in Michigan. (Their performance on analytical problems didn't change over the course of the day.) Fatigue, Dr. Wieth says, may allow the mind to wander more freely to explore alternative solutions.G) Of course, everyone's body clock isn't the same, making it even harder to synchronize natural rhythms with daily plans. A significant minority of people operate on either of two distinctive chronotypes, research shows: Morningpeople tend to wake up and go to sleep earlier and to be most productive early in the day. Evening people ten d to wake up later, start more slowly and peak in the evening.3. Attach great importance to communication online.H) Communicating with friends and colleagues online has its own optimal cycles, research shows. Sending emails early in the day helps beat the inbox rush; 6 a.m. messages are most likely to be read, says Dan Zarrella, social-media scientist for HubSpot, a Cambridge, Mass.I) Reading Twitter at 8 a.m. or 9 a.m. can start your day ona cheery note. That's when users are most likely to tw eet upbeat, enthusiastic messages, and least likely to senddownbeat tweets steeped in fear, distress, anger or guilt, according to a study of 509 million tweets sent over two years by 2.4 million Twitter users, published last year in Science. One likely factor? 'Sleep is refreshing' and leaves people alert and enthusiastic, says Michael Walton Macy, a sociology professor at Cornell University and co-author of the study. The cheeriness peaks about 1-1/2 hours later on weekends -- perhaps because people are sleeping in, Dr. Macy says.J) Other social networking is better done later in the day. If you want your tweets to be re-tweeted, post them between 3 p.m. and 6 p.m., when many people lack energy to share their own tweets and turn to relaying other s' instead, Mr. Zarrella says. And posts to Facebook at about 8 p.m. tend to get the most 'likes,' after people get home from work or finish dinner. At that time of day, they're likely to turn to Facebook feeling less stressed. 'You have less stuff to do a nd more time to give,' says Mr. Zarrella.K) Late-night drama can be found on Twitter, where emotions heat up just before bedtime, between 10 p.m. and 11 p.m., says Scott Andrew Golder, a Ph.D. candidate at Cornell University and co-author of the Twitter study. At that time, people tended to send more emotion-laden tweets, both positive and negative. Tired out by the workday, but also freed from its stresses and demands, people become 'more alert and engaged, but also more agitated,' Dr. Macy says.4. Choose the right exercise time.L) When choosing a time of day to exercise, paying attention to your body clock can also improve results. Physical performance is usually best, and the risk of injury least, from about 3 p.m. to 6 p.m., says Michael Smol ensky, an adjunct professor of biomedical engineering at the University of Texas, Austin, and lead author with Lynne Lamberg of 'The Body Clock Guide to Better Health.'M) Muscle strength tends to peak between 2 p.m. and 6 p.m. at levels as much as 6% ab ove the day's lows, improving your ability to grip a club or racquet. Another boost for physical strength comes from the lungs, which function17.6% more efficiently at 5 p.m. than at midday, according toa study of 4,756 patients led by Boris Medarov, an assistant professor of medicine at Albany Medical College in New York. N) Eye-hand coordination is best in late afternoon, making that a good time for racquetball or Frisbee. And joints and muscles are as much as 20% more flexible in the evenin g, lowering the risk of injury, Dr. Smolensky says. These body rhythms hold true regardless of how much you've slept or how recently you've eaten.1. Due to different body clocks, people may feel it difficult tolans. [16].【参考答案】:Gphysical rhythms.

[题数:10;分数:30分;参考时间:20分0秒]Passage 1The fridge is considered anecessity. It has been so since the1960s when packaged food firstappeared with the label: "store inthe refrigerator".26. The statement "In myfridgeless Fifties childhood, I wasfed well and healthily." suggeststhat ____.In my fridgeless Fifties childhood, I was fed well and healthily. The milkman came daily, the grocer, the butcher, the baker, and the ice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus (剩余) bread and mild became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on, food deliveries have ceased, fresh vegetables are almost unobtainable in the country.The invention of the fridge contributed comparatively little to the art of food preservation. A vast way of well-tried techniques already existed - natural cooling, drying, smoking, sugaring, bottling ...What refrigeration did promote was marketing - marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the globe in search of a good price. Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the wealthy countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining anartificially-cooled space inside an artificially-heated house - while outside, nature provides the desired temperature free of charge. The fridge's effect upon the environment has been evident, while[A] the author was well-fedand healthy even without a fridge in his fifties[B] the author was notaccustomed to using fridges even in his fifties[C] there was no fridge in the author's home in the 1950s[D] the fridge was in its early stage of development in the 1950s 【参考答案】:C27. Why does the author say that nothing was wasted before the invention of fridges?____[A] People would not buy more food than was necessary.[B] Food was delivered to people two or three times a week.[C] Food was sold fresh and did not get rotten easily.[D] People had effective ways to preserve their food.【参考答案】:D28. Who benefited the least from fridges according to theauthor?____its contribution to human happiness has been insignificant. If you don't believe me, try it yourself, invest in a food cabinet and turn off your fridge next winter. You may miss the hamburgers, but at least you'll get rid of terrible hum.[A] Inventors.[B] Consumers.[C] Manufactures.[D] Traveling salesmen.【参考答案】:B29. Which of the following phrases in the fifth paragraph indicates the fridge's negative effect on the environment?____[A] "Hum away continuously".[B] "Climatically almost unnecessary".[C] "Artificially-cooled space".[D] "With mild temperatures". 【参考答案】:A30. What is the author's overall attitude toward fridges?____[A] Neutral.[B] Critical.[C] Objective.[D] Compromising.【参考答案】:BPassage 2Status is a marvelous human invention that enables us to get along with one another and to determine where we "fit" in society. As we go about our everyday lives, we mentally attempt to place people in terms of their status. For example, we must judge whether the person in the library is a reader or a librarian, whether the telephone caller is a friend or a salesman, whether the unfamiliar person on our property is a thief or a meter reader, and so on.The status we assume often varies with the people we encounter, and changes throughout life. Most of us can. at very high speed, assume the status with various requirements. Much of social interaction consists of identifying and selecting among appropriate status and allowing other people to assume their status in relation to us. This means that we fit our actions to those of other people based on a constant mental process of appraisal and interpretation. Although some of us find the task more difficult than others, most of us perform it rather effortlessly.Status has been compared to ready-made clothes. Within certain limits, the buyer can choose style 31. In the first paragraph, the writer tells us that status can help us ____.[A] determine whether a person is fit for a certain job[B] behave appropriately in relation to other people[C] protect ourselves in unfamiliar situation[D] make friends with other people【参考答案】:B32. According to the writer, people often assume different status ____.[A] in order to identify themselves with others[B] in order to better identify others[C] as their mental processes change[D] as the situation changesand fabric. But an American is not free to choose the costume (服装) of a Chinese peasant or that of a Hindu prince. We must choose from among the clothing presented by our society. Furthermore, our choice is limited to a size that will fit, as well as by our pocketbook (钱包). Having made a choice within these limits we can have certain alterations made. but apart from minor adjustments, we tend to be limited to what the stores have on their racks. Status too comes ready made. and the range of choice is limited. 【参考答案】:D33. The word "appraisal" most probably means "____".[A] involvement[B] appreciation[C] assessment[D] presentation【参考答案】:C34. In the last sentence of the second paragraph, the pronoun "it" refers to "____".[A] fitting our actions to those of other people appropriately[B] identification of other people's statuses[C] selecting one's own statuses[D] constant mental process 【参考答案】:A35. By saying that "an American is not free to choose the costume of a Chinese peasant or that of a Hindu prince", the writer means ____.[A] different people havedifferent styles of clothes[B] ready-made clothes mayneed alterations[C] status come ready madejust like alterations[D] our choice of status islimited【参考答案】:D听短文Directions:In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A), B), C) and D). Then mark the corresponding letter with a single line through the center.
