2.ESunday is more like Monday than it used to be, Places of business that used to keep daytime “business hours” are now open late into the night. And on the Internet, the hour of the day and the day of the week have become irrelevant (不相关的).A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear.The law in almost all states used to require stores to close on Sunday; in most, it no longer does, It used to keep the schools open in all seasons except summer, in most, it still does. And whether the work week should strengthen its legal limits, or whether it should become more “flexible,” is often debated. How should we, as a society, organize our time? Should we go even further in relaxing the boundaries of time until we live in a world in which every minute is much like every other?These are not easy questions even to ask. Part of the difficulty is that we rarely recognize the “law of time” even when we meet it face to face. We know as children that we have to attend school a certain number of hours, a certain number of days, a certain number of years – but unless we meet the truant officer (学监) ,we may well think that we should go to school due to social custom and parents’ demand rather than to the law. As adults we are familiar with “extra pay for overtime working,” but less familiar with the fact that what constitutes(构成) “overtime” is a matter of legal definition. When we turn the clock forward to start daylight – saving time, have we ever thought to ourselves: “Here is the law in action”? As we shall see, there is a lot of law that has great influence on how organize and use time: compulsory education law, overtime law, and daylight – saving law- as well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin to look for it, we will have no trouble finding a law of time to examine and assess.67. By saying” Sunday is more like Monday than it used to be,” the writer means that __________.A. work time is equal to rest timeB. many people have a day off on Monday,C. it is hard for people to decide when to restD. the line between work time and rest time is unclear

3.Text 3When prehistoric man arrived in new parts of the world, something strange happened to the large animals. They suddenly became extinct. Smaller species survived. The large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans.That the seas are being overfished has been known for years. What researchers such as Ransom Myers and Boris Worm have shown is just how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.Dr. Worm acknowledges that the figures are conservative. One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since no baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now.Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the data support an idea current among marine biologists, that of the “shifting baseline.” The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.31. The extinction of large prehistoric animals is noted to suggest that ________.[A] large animal were vulnerable to the changing environment[B] small species survived as large animals disappeared[C] large sea animals may face the same threat today[D] slow-growing fish outlive fast-growing ones

4.The saying“He who dies rich, dies disgraced” properly means thatA． the wealthy people should give away their fortunes after deathB． the wealthy people should feel ashamed for their assetsC． the wealthy people should abandon their careers for charitiesD． it is shameful for the wealthy people to keep their wealth till death

    Practice 1　　You should spend about 40 minutes on this task.　　Write about the following topic:　　People can perform everyday tasks, such as shopping and banking as well as business transactions, without meeting other people face-to-face. What are the effects of this on an individual and society as a whole?　　You should write at least 250 words.

    正确答案： 【参考范文】
    Asking if virtual life will replace real life is like asking if singles' chatrooms will replace real dating. Human face-to-face interaction is, and will always be, the most effective form of communication.
    First and foremost. Live meetings deliver more potent experiences that virtual meetings cannot. They deliver motivation along with messages, and inspiration with information. Face to face allow people to observe others to make better judgment or use more than words to express their ideas. That's why corporations that want to inspire a sales force to perform better or build confidence with customers are continuing to rely on the punch that live events deliver, namely, expos.
    Still, while the virtual meetings will never entirely replace the live ones, the technology has a place within physical events, which shows the advantage over face-to-face communication. The shortcomings of the traditional meeting model, with a presenter talking on the stage and passive audience wasting time, have become clear with the rise of interactive and social networking instruments. These advances provided companies to incorporate better peer-to-peer and audience-to-presenter interaction. On the contrary, virtual life also isolates people without notice. Due to lack of timely feedback and negotiation, confusion and misunderstandings will spring out. High technology can hardly show emotions and feeling fully and properly. Emoticons can not tell everything. In other words, it is difficult to convey sarcasm or anger in an email or a text.
    In summary, face-to-face and virtual chat will coexist in modem society. Personally, I am not in favor of having arguments electronically. Technology can be great to get in contact with someone and very convenient when they further along in a relationship, but never use it as a replacement for the real thing. For all of its usefulness, it is very hard to cuddle with a cell phone.

    问答题
    The world of work is changing rapidly. Working conditions today are not the same as they used to be, and people no longer devote their life to doing one job for life. Write a composition of about 400 words to discuss the possible causes of these changes, and give your suggestions as to how people should prepare for work in the future.

    正确答案：
    Vast changes are taking place in the world's labour market, so it comes as no surprise that people's views on occupations are no longer the same as before. Nowadays, many people are inclined to do one job in their lives, while others change their job frequently. How has this phenomenon come about? I believe there are several reasons.
    As we are ushered into a new era, the demand for labour has shifted its focus. In the past, companies only required their employees to be loyal and to follow the supervisors' instructions to the letter. But nowadays, employees with imagination and creativity are most welcome in the job market. Therefore, the employer is always happy to see new faces and fresh ideas.
    People's attitudes toward work have also altered. They tend to believe that each person has his talents in many fields. After they have devoted themselves to a particular area for a few years, they may be bored with what they have been doing all along, and would like to make endeavors in some other field for a change. Some of them assume that they can make more accomplishments in a new job, while others simply hunger for new challenges and adventures.
    Finally, the world itself is changing at a bewildering pace. Some professions flourish while others slump. And there are new professions emerging every day. Thus, spurred to adapt themselves to the new, ever-changing circumstances, people will have to acquire new knowledge and skills, so that they can work in new fields and make more money.
    However, there are also evident disadvantages to changing one's job frequently. Once you switch to a new profession, you have to start from scratch. For scientists, as well as engineers or doctors, long-term training is indispensable to their career. Job-hopping, therefore, is not practical for them. For people whose jobs need little special training, work experience means much more. Hopping to a new lob, they have to gather experiences in the new field from the very beginning.
    Taken as a whole, it is my conclusion that people living in the present IT era have to get fully prepared for what is drawing near. It will be advantageous if they can be open-minded enough to acquire various types of knowledge and skills, and get psychologically prepared for the swift changes occurring with each passing day.

To what extent do you agree or disagree?　　You should write at least 250 words.

    正确答案： 【参考范文】
    Daily communication tools make the distance between people shrink. There are various ways such as mobile phones, Facebook, Twitter and E-mail which changes our life from daily life to work style. As for the dramatic and rapid changes, people in all walks of life hold different opinions. Personally, it is a must to be tolerant of the new technological innovations.
    It is undeniable that all these high-tech tools can alienate the virtual interpersonal relationship that exists between people. If we want to tell somebody something, we do not have to really see him, and we can send a short message, a E-mail, or leave one on Facebook. Regardless of the convenience, face-to-face conversations are still one of the best ways to understand each other.
    High technologies provide us with more choices which can yield higher efficiency, which can be illustrated from three perspectives. Firstly, it is a useful time-saver for people greatly enjoy social life. Social network enable them to spare the trouble of heavy traffic in rush hours when they need to have contact with friends. Secondly, it is also a money-saver. Compared with the high cost of an official visit to someone or some place, chatting on-site or through telephone is much cheaper. If each company has an E-conference system, information sharing should never be a daydream in the era of information. Lastly, and most importantly, with the great help of new inventions, people may communicate with others without being limited to geographical difference. Namely, no matter where one stays, he or she can get in touch with people on the Internet at any time.
    In summary, modem technologies are excellent assistants of our life and work, so it is wise to accept them and make full use of them properly.

Why does this happen? What are the effects of this on family life and society as a whole?　　You should write at least 250 words.

    正确答案： 【参考范文】
    Imagine that you are in a car parked on the road during rush hour for more than one hour. You may be regretful for wasting such a long time and losing time to get together with family. This question will be the main topic of the following essay; besides, it will also tall about its effects at the same time.
    As for those brief-case men and white collar, they have to cope with a lot of issues at work. And thus only leave their families a small amount of time. There are many reasons for this. Firstly, living in modern society, it is impossible to avoid the pressure from both inside and outside. In order to maintain a good public praise or just get a further promotion, people not only care about their own feelings but those of others’ as well. Secondly, the world is full of material stimulation, encouraging people to chase their happiness, materially. Without money, no one can live in society in his most-wanted way. In order to own a satisfactory living standard, they have no choice but work harder. Last but not least, the advances of modern technology enable people to communicate with each other without seeing each other. This is almost a tragedy for mankind. If we spend all our time on the Internet, we will lose so many traditional ways like face-to-face talking and body language.
    Also, the influence of this issue should never be neglected for society: Cumulative stress from work becomes the potential health killer. People are easily infected with psychological illnesses like anxiety, eccentricity and insomnia. In addition, due to materialism and realism, society as a whole has easily become money-oriented, where people make judgments of achievements just according to the materials. Finally, over-dependence on telecommunication leads to the lack of recalling traditions and rethinking of the history and culture, which is a shame for civilized people.
    Naturally, a profession is fundamental for all modern city dwellers without any question. However, the family is the ultimate destination for them indeed.
