We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alternating(交替) with some 16-17 hours' wakefulness and that the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified.
　　The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed（顛倒的） routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts(輪班) are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently.
　　The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night-shift workers was carried out by Brown in 1957. She found a high incidence (發(fā)生率) of disturbed sleep and other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work.
　　This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the pressure of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People occupied in normal daytime work will have a high temperature during the hours of wakefulness and a low one at night; when they change to night work the pattern will only gradually go back to match the new routine and the speed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in terms of performance. Therefore, by taking body temperature at two-hour intervals(間隔時間) throughout the period of wakefulness, it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for selection. So far, however, such a form of selection does not seem to have been applied in practice.
小題1:The main problem of the round-the-clock working system lies in       .
A．the inconveniences brought about to the workers by the introduction of automation
B．the disturbance of the daily life cycle of workers who have to change shifts too frequently
C．the fact that people working at night are often less effective
D．the fact that it is difficult to find a number of good night workers
小題2:The best solution for implementing the 24-hour working system seems to be       .
A．to change shifts at longer intervals.
B．to have longer shifts
C．to arrange for some people to work on night shifts only
D．to create better living conditions for night workers
小題3:It is possible to find out if a person has adapted to the changes of routine by measuring his body temperature because       .
A．body temperature is higher when the cycle of sleep and wakefulness alternates
B．body temperature changes when he changes to night shift or back
C．the temperature reverses when the routine is changed
D．people have higher temperatures when they are working efficiently
小題4:Which of the following statements is NOT TRUE?
A．Body temperature may serve as an indication of a worker's performance.
B．The selection of a number of permanent night shift workers has proved to be the best solution to problems of the round-the- clock working system.
C．Taking body temperature at regular intervals can show how a person adapts to the changes of routine.
D．Disturbed sleep occurs less frequently among those on permanent night or day shifts.

小題1:B
小題2:C
小題3:D
小題4:B

試題分析：文章大意：本文主要介紹了24小時倒班工作存在的主要問題，并提出了某些解決辦法，但都沒有明顯成效。
小題1:B 細(xì)節(jié)題。根據(jù)第二段It normally takes from five days to one week for a person to adapt to a reversed（顛倒的） routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts(輪班) are changed every week可知24小時工作制的工人們常常被頻繁更換工作時間。故B正確。
小題2:C 細(xì)節(jié)題。根據(jù)文章第二段的This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently.
可知換班時間應(yīng)該延長，故C正確。
小題3:D 細(xì)節(jié)題。根據(jù)文章最后一段的People occupied in normal daytime work will have a high temperature during the hours of wakefulness and a low one at night可知人體的體溫是隨著上班時間的改變而改變的，故D正確。
小題4:B 推理題。根據(jù)文章最后一段的it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for selection. So far, however, such a form of selection does not seem to have been applied in practice可知選擇永久的夜間值班者僅僅是一種基礎(chǔ)的方法，但不是最佳的方法，故選B。

My grandmother Adele loved culture and was generous with its gifts. When I was a child, she took me to museums, restaurants, dances. She showered me with gifts from her travels around the world. But I can only remember her giving me one book—a book that, to this day, I have not read. She presented me with her own favorite childhood book: Hans Brinker. My grandmother was happy to share this book with me. She even decorated the title page with her proud writing.
I tried to read it. I adored reading, and would dive into a new pile of books from the library all at once. But something about Hans Brinker just wouldn’t let me in. The story was set in Holland, a long time ago. It felt dull and unfamiliar—even though I was a fan of classics of other times and places. I simply read the first pages over and over. I could not progress.
Standing on a bookshelf in our living room, the book was like something I avoided. It scolded me for not being interested, for not trying hard enough, for disappointing my grandmother.
The book started to fit in, almost forgotten, until Adele asked. Had I read it? Did I like it? Always determined, she wanted to know the answer. I would make some kind of excuse, feel bad, and open it again, hoping for a new reaction. The book weighed on me.
Years passed and finally Adele and I both accepted that I would never read Hans Brinker. Eventually I cleared the book from the shelf. The Hans Brinker experience led me to set a rule that I’ve lived by ever since: Do not ask about a book given as a gift. Don’t ask, despite your desire to discuss it to grow closer. The desire for such connection is what gives book-giving with special meaning—and increases the owner’s possibility to be a letdown.
Guilt is basically the same as for all gifts, though. If the giver doesn’t have the pleasure of seeing or hearing about the gift being enjoyed, and asks whether it is, then the owner—unless she can truthfully say “yes”—either has to admit to not liking the present, or else lie on the spot. Neither is pleasant. So, don’t ask.
小題1: When the author was a kid, his grandmother ________.
A．took him to travel around the world a lot
B．loved to take him to museums and stores
C．shared her childhood stories with him

小題2:What does the author think about the book his grandmother gave him?
A．Boring.B．Interesting.C．Puzzling.D．Disappointing.
小題3:The underlined sentence “The book weighed on me” in Paragraph 4 probably means _______.
A．the book is too heavy for the author to carry
B．the author feels stressful facing the book
C．the book is full of powerful viewpoints
D．the author keeps reading the book
小題4:. The author learns from the Hans Brinker’s experience that never________.
A．give others books as gifts
B．lie to people who give you gifts
C．get close to others through gifts
D．talk about the books given as gifts

Local businessmen are increasingly facing competition from online retailers. Larry Pollock, owner of Camera Co/Op on South Congress, said he has been dealing with this kind of problem for years, even before the Internet. The struggle began with mail-order catalogues(目錄), which are similar to online retailers in that they have few employees to pay, no sales tax fees and no business venue to lease and manage.
“Their overhead is lower, but they don’t offer a service like we do,” Pollock said.
Pollock, however, said providing a valuable service to customers does not always guarantee continued sales.
“We spend 30 minutes to an hour with somebody and they go home and buy it on line,” he said.
According to the state comptroller’s office, online shopping is developing at a more rapid rate than traditional businesses.
In spite of how fair or unfair online shopping may be to the local businessmen, consumers will continue to turn to the Internet for its variety and accessibility, said Mitch Wilson, an online shopper. “You have a larger selection and it's easier to compare prices.”
Wilson said he built his personal computer and paid a third of the price by shopping on line.
“Before the Internet, I would have had to go and buy an assembled computer from somebody like Dell,” he said. “Before I started shopping on line I could never find all the pieces I wanted. No single store had everything needed, so shopping on line saved me from having to buy from Dell.”
Janny Brazeal, a psychology freshman, said online shopping is too impersonal.
“’d rather see it in person, touch it, know that I’m getting it,” she said.
Brazeal also said she would not give out her credit card number or other personal information on line no matter how safe the site claims it is.
小題1:Larry Pollock has been facing the problem _____.
A．before long
B．a(chǎn)fter the Internet
C．since there were mail-order catalogues
D．since he worked as a businessman
小題2:According to the passage, which of the following is WRONG?
A．Traditional business can provide valuable ser- vices to customers.
B．People can get cheaper goods from traditional business.
C．More and more people will turn to the Internet for their needs.
D．There are still many people who don’t like on- line shopping.
小題3: Mitch Wilson prefers to build his personal compu- ter by shopping on line because _____.
A．he can easily get what he needs at a lower price
B．he can not get the price at traditional businessman
C．he is not satisfied with the service of local busi- nessman
D．the quality of Dell is not satisfying

As the new semester begins，millions of college students across the country are trying hard to remember how best to write a paper-or，more likely，how best to delay that paper．
Procrastination is the thief of time and a lot of students suffer from it．They can spend whole days in the library doing nothing but staring into space，eating snacks，surfing the Internet，watching videos and looking at their pretty peers sitting around them，who，most likely，are doing nothing either．
Paralyzed by their habit to procrastinate，they write micro blogs about their fears，asking their online friends if they sometimes have the same issue．But this does nothing to solve their problems．
According to a recent report by the BBC，95 percent of us procrastinate at some point and 20 percent of the world’s population are procrastinators，complicating their lives with their continual delaying of tasks．
Procrastinators like to find excuses to justify their behavior，but BBC columnist Rowan Pelling says they are all wrong．Many procrastinators tell themselves they are perfectionists who work best under pressure．Pelling says this is nonsense，as work done at the last minute is more likely to have mistakes than work done on time．
She says the behavior of procrastinators often makes them feel flustered and ashamed，inconveniences others，and annoys loved ones．
Fortunately，social seientists have made tireless efforts to understand this behavioral shortcoming and offer strategies to control it．Piers Steel，a Canadian social scientist and author of The Procrastination Equation，believes humankind is“designed”to procrastinate．Nevertheless，he suggests a couple of good ways to get through the task at hand．
The first one is obvious：Break the task down into small pieces and work your way through them methodically．
The second is clever：Give a trusted friend a sum of money and tell them that if you don’t complete the task you have undertaken by a specific time，they can keep it or donate it to a cause you hate.
小題1:What does the underlined word“Procrastination” in the second paragraph refer to?

Kevin Spacey plays Francis J. Underwood, a cold-blooded Democrat who moves his way up the political ladder by any means necessary. He often uses his under-exposure in media to carry out misdeeds that will later benefit him.
The revenge(報仇) theme plays a heavy role throughout the storyline, Underwood, who had high hopes for an appointment as Secretary of State in the first season, was betrayed by the US President and his former colleagues. He and his wife then conducted a plan of revenge and swore to unseat those who turned their backs against him. Through their plan, Underwood’s own hunger for power grew and empowered him to get rid of whoever stood in his Way.
The release of the trailer(預(yù)告片) of the second season excited millions of viewers around the world, including US President Barack Obama, who has been a loyal fan since the series debuted. Obama expressed his admiration for Underwood. “This guy’s getting a lot of stuff done,” he said. Although the President is anxious to watch the story unfold, he’d like to do it at his own pace. After the release of the second season on February 14, 2014, Obama sent words on his Twitter account, “Tomorrow: @HouseOfCards. No spoilers , please.”
The second season has promised to be darker, with more unexpected turnouts, and is to include more Chinese elements. “Perhaps the team, including myself, has realized that in the next decade, Asia will be an extensively important region, and China will play an active role in its transition and change,” says Spacey.

A tent can be one of the more costly items on your camping equipment shopping list. It is definitely something that you need to consider carefully.
By seeing a tent for real you will be able to get a better impression of its size and construction in the traditional shop. However，the downside is that，unless you are experienced，you may miss out some of the details that the manufacturer’s promotional material makes clear. Cheap tents often look similar to the quality models they are mimicking(模仿)，but you can be sure that they use inferior(次的) materials and probably have lower design standards.
Shop staff are often campers themselves. That means they usually can give lots of advice. If a shop assistant agrees with your own conclusions，that will be great；if they try to change your decision with a clear and reasonable argument，then that will be worth considering；if they just try to bamboozle(欺騙)，or even bully，you then walk away.
The Internet is a wonderful tool，and so long as you know how to make the most of search engines and put in a little effort，you really have the perfect answer waiting to be found. That answer will be different for every camper as each of us has different needs. Don’t be surprised to see your favorite criticized somewhere，but if you see too much criticism，then you had better start thinking again. No problem. You won’t have spent anything yet，so think of it positively as a large expense saved.
Probably the best approach，if you have the time，is to research tents online and make a short list. Then try to inspect those tents at nearby shops. Then you can make a final decision on where to buy your chosen model based purely on total cost.
小題1:The underlined word “downside” in Paragraph 2 means “________”．
A．disadvantageB．instructionC．a(chǎn)rgumentD．principle
小題2:It can be concluded from the third paragraph that________.
A．shop assistants usually enjoy going camping
B．shop assistants usually have practical advice
C．you should consider your idea repeatedly
D．it is impolite for you to trouble shop assistants
小題3:You can make use of the Internet to________.
A．meet your different needs
B．find the answer for every camper
C．help you out of trouble
D．find your favorite tent
小題4:Which of the following would be the main idea of this passage?
A．It is good to buy your tent in the traditional shop.
B．You’d better buy a tent with the help of the Internet.

In today’s world, almost everyone knows that air pollution and water pollution are harmful to people’s health. However, not all the persons know that noise is also a kind of pollution, and that is harmful to human health, too.
People who work and live under noisy conditions usually become deaf. Today, however, scientists believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of the workers who print newspapers and books, and who weave（織） cloth become deaf. Quite a few people living near airports also become deaf. Recently it was discovered that many teenagers in America could hear no better than 65-year-old persons, for these young people like to listen to pop music and most of pop music is a kind of noise. Besides, noise produced by jet planes or machines will make people’s life difficult and unpleasant, or even make people ill or even drive them mad.
It is said that a continuous noise of over 85 decibels（分貝） can cause deafness. Now the governments in many countries have made laws to control noise and make it less than 85 decibels.

Hacking our senses to boost learning power
Some schools are pumping music, noises and pleasant smells into the classroom to see if it improves exam results. Could it work? Why do songs stick in our heads? What does your school smell like? Is it noisy or peaceful?
It might not seem important, but a growing body of research suggests that smells and sounds can have an impact on learning, performance and creativity. Indeed, some head teachers have recently taken to broadcasting noises and pumping smells into their schools to see whether it can boost grades. Is there anything in it? And if so, what are the implications for the way we work and study?
There is certainly some well-established research to suggest that some noises can have a harmful effect on learning. Numerous studies over the past 15 years have found that children attending schools under the flight paths of large airports fall behind in their exam results. Bridget Shield, a professor of acoustics (聲學(xué)) at London South Bank University, and Julie Dockrell, from the Institute of Education, have been conducting studies on the effects of all sorts of noises, such as traffic and sirens (汽笛), as well as noise generated by the children themselves. When they recreated those particular sounds in an experimental setting while children completed various learning tasks, they found a significant negative effect on exam scores. “Everything points to a bad impact of the noise on children’s performance, in numeracy, in literacy, and in spelling,” says Shield. The noise seemed to have an especially harmful effect on children with special needs.
Whether background sounds are beneficial or not seems to depend on what kind of noise it is — and the volume. In a series of studies published last year, Ravi Mehta from the College of Business at Illinois and his colleagues tested people’s creativity while exposed to a soundtrack made up of background noises — such as coffee-shop chatter and construction-site drilling — at different volumes. They found that people were more creative when the background noises were played at a medium level than when volume was low. Loud background noise, however, damaged their creativity.
Many teachers all over the world already play music to students in class. Many are inspired by the belief that hearing music can boost IQ in later tasks, the so-called Mozart effect. While the evidence actually suggests it’s hard to say classical music boosts brainpower, researchers do think pleasant sounds before a task can sometimes lift your mood and help you perform well, says Perham, who has done his own studies on the phenomenon. The key appears to be that you enjoy what you’re hearing. “If you like the music or you like the sound — even listening to a Stephen King novel — then you do better. It doesn’t matter about the music,” he says.
So, it seems that schools that choose to prevent disturbing noises and create positive soundscapes could enhance the learning of their students, so long as they make careful choices. Yet this isn’t the only sense being used to affect learning. Special educational needs students at Sydenham high school in London are being encouraged to revise different subjects in the presence of different smells — grapefruit scents for maths, lavender for French and spearmint for history.
小題1:The four questions in the first paragraph are meant to ________.
A．create some sense of humour to please the readers
B．provide the most frequently asked questions in schools nowadays
C．hold the readers’ attention and arouse their curiosity to go on reading
D．declare the purpose of the article: to try to offer key to those questions
小題2:What does the conclusion of the studies of noise conducted by Bridget Shield and Julie Dockrell suggest?
A．Peaceful music plays an active role in students’ learning.
B．Not all noises have a negative impact on children’s performance.
C．We should create for school children a more peaceful environment.
D．Children with special needs might be exposed to some particular sounds.
小題3:Ravi Mehta’s experiment indicates that ________.
A．students’ creativity improves in a quiet environment
B．we may play some Mozart music while students are learning
C．a(chǎn) proper volume of background noises does improve creativity
D．noise of coffee-shop chatter is better than that of construction-site drilling
小題4:Towards the positive impact of appropriate background sound and smell on students’ learning and creativity, the author’s attitude is ________.
A．a(chǎn)mbiguousB．doubtfulC．negativeD．supportive
小題5:Which of the following is most likely to follow up the research findings?
A．Experts’ research into other senses that can improve students’ grades.
B．More successful examples of boosting learning power by using music.
C．Suggestions for pumping lots of pleasant smells into school campuses.
D．Debates on whether noises can really have positive effect on students’ performance.
