(80) Other experts feel that giving the worker freedom to do his job in his own way is important. There is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modem factory with its complicated machinery which must be used in a fixed way. Thus, although freedom of choice may be important, usually very little can be done to create it.
Another important consideration is how much a worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are now experimenting with having many small production lines rather than a large one, so that each worker contributes more to the production of the cars on his line. It would seem that not only is degree of the worker's contribution an important factor, therefore, it is also one we can do something about. To what extent does more money lead to greater productivity？ The workers themselves certainly think this is important. But perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if we make their jobs more interesting, they will want neither more money nor shorter working hours.
Varied jobs, in writer's opinion, will ______.
A．offer greater productivity
B．drive workers to work harder
C．make workers more productive
D．make worker's life more enjoyable, but do not make them more hardworking
Does this sound familiar？ You have probably read something like it in magazines or books, or seen it in a film. Why is it so popular？ One of the reasons is that it reflects the fears of many people; fear of the unknown fear of what is not understood or, at least, fear of something that is not completely understood.
The fact is that every day it seems that computers take control of another area of our lives. Some
factory jobs are now done by robots and the robots are controlled by computers. Our bank accounts are managed by computers. At the airport, our tickets are sold by a computer. Certainly, many of these operations are made more
efficient by computers, but our admiration is sometimes mixed with unsafe feelings. And this lack of safety is caused by the fact that we do not know how computers do these things, and we really don't know what they might do next. But we can find out how computers work, and once we understand them, we can use computers instead of worrying about being used by them. Today, there is a new generation of computer wizards who know exactly how computers get things done. These young men and women, usually university students, are happy to sit for hours, sometimes for days, designing programs, not eating, not sleeping, but discovering what can be done by these wonderful slaves which they have learned to control. These computer wizards have learned to use the computer and search for new tasks for their machines.

(3)、The author mentions computer wizards in order to point out that ______ .
A：computers can be controlled by man
B：there should be more people devoted to computers
C：only young people are interested in computers
D：more time and energy is required to control computers
(4)、This passage is probably written to suggest that ______ .
A：some day computers can deal with all human problems
B：computers can be used in place of traveling to our jobs
C：people should not fear computers
D：computer technology will not meet people's needs in various situations

Trying to Find a Partner
One of the most striking findings of a recent poll in the UK is that of the people interviewed, one in two believes that it is becoming more difficult to meet someone to start a family with.
Why are many finding it increasingly difficult to start and sustain intimate relationships？ Does modern life really make it harder to fall in love？ Or are we making it harder for ourselves？
It is certainly the case today that contemporary couples benefit in different ways from relationships. Women no longer rely upon partners for economic security or status. A man doesn't expect his spouse to be in sole charge of running his household and raising his children.
But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence.
In theory, finding a partner should be much simpler these days. Only a few generations ago, your choice of soul mate (心上人) was constrained by geography, social convention and family tradition. Although it was never explicit, many marriages were essentially arranged.
Now those barriers have been broken down. You can approach a builder or a brain surgeon in any bar in any city on any given evening. When the world is your oyster (牡蛎), you surely have a better chance of finding a pearl.
But it seems that the old conventions have been replaced by an even tighter constraint: the tyranny of choice.
The expectations of partners are inflated to an unmanageable degree: good looks, impressive salary, kind to grandmother, and right socks. There is no room for error in the first impression.
We think that a relationship can be perfect. If it isn't, it is disposable. We work to protect ourselves against future heartache and don't put in the hard emotional labor needed to build a strong relationship. Of course, this is complicated by realities. The cost of housing and child-rearing creates pressure to have a stable income and career before a life partnership.
What does the recent poll show？
A．It is getting more difficult for a woman to find her husband.
B．It is getting increasingly difficult to start a family.
C．It is getting more difficult for a man to find his wife.
D．It is getting increasingly difficult to develop an intimate relationship with your spouse.
When you leave your office to attend meetings or travel on business, what would happen to your business routine？ Of course, faxes and e-mails would be still sent to your fax machine or e-mail box, but you cannot read them and make prompt reaction timely. When your clients need you to make some urgent modifications on your work and you are neither in the office nor carrying relevant documents, what can you do？ Maybe you have to say "sorry" to the clients. But, your business will be affected, the clients will be unhappy and disappointed because of your delay, and you will lose a lot of business opportunities.
In fact, very frequently, you need to check, reply, distribute, display, modify or read some materials when you are not in your office. You must get out of this dilemma. The best solution to normally handle your-business anywhere anytime and not to disappoint your clients is to let your office "move" with you. Thus, you can have convenient, prompt, safe, reliable and reasonably priced communications and office faculty anywhere anytime. With the development of communications technology, network application and wireless interconnection, mobile office has become simpler and smaller, and even can be realized via one mobile phone with data communications function. Thus, mobile office has already been put into your pocket, and office mobility has been realized. Mobile office has provided people with convenient, casual working environment, but at the same time it still has some unsatisfactory aspects such as mismatching equipment interface and inadequate battery. Nevertheless, we believe that with technical progress, people can certainly overcome all kinds of difficulties. Mobile office will make your career successful, and will realize the dream of completely free communication. Users will enjoy more colorful life and better working environment, and users' living standard, working efficiency and even enterprises' production efficiency will certainly be immensely raised.
It can be inferred from the passage that______.
A．mobile office is the only way by which people could enjoy prompt and safe working environment
B．with the development of science, mobile office comes to our life inevitably
C．people had no convenient and reliable communications and office faculty before
D．mobile interconnection platform. and its application systems is the core of mobile office

Are you superstitious？ No, of course not. Do you believe in magic (魔法), and luck charms (护身符), and elves or gremlins (小精灵) ？ Certainly not, but if I should greet you with the usual How's business？" You'll answer "Oh, just so-so" although your business is profiting greatly. When you are successful in some venture you might say you were just lucky. And yet, you know it was probably due to your a bility and hard work. Why？ Sometimes you knock on wood because wood was once a tree and there is a primitive belief that protective gods inhabit trees and knocking on wood attracts their attention so they may be credited with your successes.
If I should sneeze, only the strongest of you could refrain(克制而不) from saying "God bless you". Why bless this unsanitary (不讲究卫生的) habit？ Our ancestors believed that a sneeze opened the body to invasion by devils, and invoking (召唤) the name of God made the devils get out in a hurry. You may not realize it, but you express this same "devil invasion" when you say, "Whatever can have gotten into that child？" or "I wonder what possessed me to do that？"
Although they may no longer be believed, evidences of superstitions that have had their origins in the primitive fear of the unknown still exist in modern language and gestures.
The author ______.
A．believe that most people are superstitious
B．believe that very few people are superstitious
C．believes that there are still some evidences of superstitions in what we say and what we do
D．is superstitious
A.on road
B.onsite
C.on track
I'm hardly alone, which is bad news for the world's oceans. Partly because more and more sushi is demanded, we're fast fishing out our seas. Some researchers estimate that if we don't change the way we harvest the oceans, all the commercial fisheries (捕鱼业) in the world could disappear as early as 2048. That could mean no more fish to buy in your local supermarket.
Fortunately, scientists are looking for ways to fish sustainably (可持续地). One method is a quota system that sets a limited amount to every fisherman or corporation who wants a share of the total catch for certain sea area. These catch shares get rid of the possibility to over fish.A recent study in Science found that the system can prevent fishery from dying and even make it better over time. "It's truly a win-win situation," says Steven Gaines, a marine biologist at the University of California at Santa Barbara and one of the study's co-authors.
Consumers also can help save the seas through the fish they buy. California's Monterey Bay Aquarium Institute is coming out with pocket guides to sustainable sushi. The researchers base their ratings on the health of a wild fish's population as well as the impacts of fish-farming operations. Oysters, for example, grow fast and can be farmed sustainably, but salmon can't. The researchers also take fishing practices into consideration: catching big-eye tuna (金枪鱼) can cause its nearby fish to die, which certainly no one wants to see. It is hoped that, by making the right choice, consumers can encourage businesses to fish in a more sustainable way.
