When should people be made to retire? 55? 65? Should there be a compulsory age limit?
Many old people work well into their 70s and 80s, running families, countries or corporations. Other people,however, despite being fit and highly talented, are forced to retire in their fifties or even earlier because of the regulations of a company or the nation. This essay will examine whether people should be allowed to continue working as long as they want or whether they should be encouraged to retire at a particular stage.
Some people think there are several arguments for allowing older people to continue working as long as they are able. First of all, older employees have an immense amount of knowledge and experience which can be lost to a business or organization if they are made to retire. A second point is that older employees are often extremely loyal employees and are more willing to carry out company policies than younger less committed staff. However, a more important point is regarding the attitudes in society to old people. To force someone to resign or retire at 60 indicates that the society does not value the input of these people and that effectively their useful life is over. Age is irrelevant to a working life, surely if older employees are told they cannot work after 60, this is age discrimination. That they become old does not necessarily mean they are going to be sick. Old people could be more aware, experienced and committed than some youngsters.
Others, however, think that allowing older people to work indefinitely is not a good policy. Age alone is no guarantee of ability. Old people are only ambitious workaholics who are too selfish and self-centered to believe that a younger person could do better. Actually, many younger employees have more experience or skills than older staff, who may have been stuck in one area or unit for most of their working lives. Having compulsory retirement allows new ideas in an organization. In addition, without age limits, however, many people would continue to work purely because they did not have any other plans or roles. A third point of view is that older people should be rewarded by society for their life’s labor by being given generous pensions and the freedom to enjoy their leisure. We now have youngsters who can’t find jobs because old people are choosing not to retire. Old people are not retiring because this new generation of “old people” think they will never die due to modern advances in medicine.
With many young people unemployed or frustrated in low-level positions, there are often calls to compulsorily retire older workers. However, this can affect the older individual’s freedom and right to work and can deprive(剥夺) society of valuable experience and insights. I feel that giving workers more flexibility and choice over their retirement age will benefit society and the individual.What is the purpose of this passage?

The passage is arranged as follows:
Supermarkets are trying out new computers that make shopping carts more intelligent（具备智能的）. They will help shoppers find paper cups or toilet soap, and keep a record of the bill.
The touch-screen devices（触摸屏装置）are on show at the Food Marketing Institute’s exhibition here this week. “These devices are able to create value and get you around the store quicker,” said Michael Alexandor, manager of Springboard Retail Networks Inc, which makes a smart cart computer called the Concierge.
Canadian stores will test the Concierge in July. A similar device, IBM’s “Shopping Buddy”, has recently been test-marketed at Stop & Shop stores in Massachusetts.
Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf.
“The whole model is driven by advertisers’ need to get in front of shoppers,” said Alexandor. “They’re not watching 30-second TV ads anymore.”
People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system（系统）that will organize the trip around the store. If you’re looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them.
The device also keeps a record of what you buy. When you’re finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay.
The new computerized shopping assistants don’t come cheap. The Buddy devices will cost the average store about $160,000, and the Concierge will cost stores about $500 for each device.
53. The underlined word “they” (paragraph 1) refers to______.
A. supermarkets B. shop assistants
C. shopping carts D. shop managers
54. Which of the following is the correct order of shopping with computerized shopping carts?
a. Start the system. b. Make a shopping list.
c. Find the things you want. d. Go to a self-checkout stand.
A. abdc B. bacd C. acbd D. bcad
55. We can learn from the last paragraph that______.
A. intelligent shopping carts cost a large sum of money
B. the Concierge is cheaper than the Buddy devices
C. shop assistants with computer knowledge are well paid
D. average stores prefer the Concierge to the Buddy devices
56. What might be the most suitable title for the text?
A. New age for supermarkets B. Concierge and Shopping Buddy
C. New computers make shopping carts smarter
D. Touch-screen devices make shopping enjoyable
The twentieth century saw greater changes than any century before: changes for the better, changes for the worse; changes that brought a lot of benefits（益处） to human beings, changes that put man in danger. Many things caused the changes, but, in my opinion, the most important was the progress in science.
Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure（结构）of matter and of the universe; it has brought us a better understanding of the nature of life and of its continuous development. Technology —the application（应用）of science —has made big advances that have benefited us in nearly every part of life.
The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science — a wider and deeper knowledge in all fields of learning; in applied science — a more reasonable sharing of material benefits, and better protection of the environment.
Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind. The application of science and technology to the development and production of weapons（武器）of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons, Although their actual use has so far occurred only in the Second World War, the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.
William Shakespeare said, "The web of our life is of a mingled yarn (纱线), good and ill具together. " The above brief review of the application of only one part of human activities – science—seems to prove what Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?
73.From the fourth paragraph, we can infer that________.
A. a great many nuclear weapons were actually used for war
B. a large number of nuclear weapons should have been used for war
C. the author is doubtful about the ruin of human beings by nuclear weapons
D. the author is anxious about the huge number of nuclear weapons on the earth
74.The underlined word "mingled" in the last paragraph most probably means________.
A. simple B. mixed C. sad D. happy
75.What do you think the author is most likely to suggest if he continues to write?
A. Further application of science to war.
B. More reading of William Shakespeare.
C. Proper use of science in the new century.
D. Effective ways to separate the good from the ill.
When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.
Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock（家畜）.During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.
People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy-saving.
House-building becomes a great challenge（挑战）to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy-saving houses.
56．What did people begin to consider as electricity was no longer cheap?
A．The climate of their areas. B．The energy for their houses.
C．The fashions for their houses. D．The building materials for their houses.
57．People in some areas gain a source of heat by _________.
A．keeping their livestock downstairs
B．protecting their livestock from the cold
C．sharing their houses only with their cows
D．living on the second floor with their livestock
58．The underlined words “natural law” in the third paragraph refer to the fact that ________.
A．heat raises the temperature in the houses
B．heat goes in the upward direction
C．heat goes up if temperature is raised
D．heat increases the temperature of rocks
59．From the passage, we can conclude that __________.
A．people will no longer consider building materials in the future
B．energy-saving buildings will become more popular in the future
C．almost all people will move into the houses heated by large rocks
D．energy engineers will devote themselves only to modern technology
Good tool design is important in the prevention of overuse injuries. Well-designed tools and equipment will require less force to operate them and prevent awkward（别扭的）hand positions. They will allow the worker to keep the elbows（肘）next to the body to prevent damage to the shoulder and arm.
Overuse injuries can therefore be prevented or reduced if the employer provides, and workers use:
●power tools rather than having to use muscle（肌肉）power
●tools with specially designed handles that allow the wrist（手腕）to keep straight . This means that hands and wrists are kept in the same position as they would be if they were hanging relaxed at a person’s side
Figure1. Bend the tool, not the wrist
●tools with handles that can be held comfortably by the whole hand. This means having a selection of sizes—remember that tools that provide a comfortable firm hold for a person with a very large hand may be awkward for someone with a very small hand. This is a particularly important consideration for women who may use tools originally designed for men.
●tools that do not press fingers (or flesh) between the handles, and whose handles do not have sharp edges or a small surface area.
60. What is the best title for the passage?
A. Good Tool Design for Women B. Importance of Good Tool Design
C. Tool Design and Prevention of Injuries D. Overuse of Tools and Worker Protection
61. Which of the following describes a well-designed tool?
A. It’s kept close to the body. B. It fully uses muscle power.
C. It makes users feel relaxed. D. It’s operated with less force.
62. What is Figure 1 used to show?
A. The effective use of the tool. B. The way of operating the tool.
C. The proper design of the handle. D. The purpose of bending the wrist.
63. In choosing tools for women, _____of the handle is the most important.
A. the size B. the edge C. the shape D. the position
PITTSBURGH – For most people, snakes seem unpleasant or even threatening. But Howie Choset sees in their delicate movements a way to save lives.
The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters or other emergencies.
Dan Kara is president of Robotics Trends, a Northboro, Mass.-based company that publishes an online industry magazine and runs robotics trade shows. He said there are other snake-like robots being developed, mainly at universities, but didn’t know of one that could climb pipes.
The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be controlled with a joystick(操纵杆). They move smoothly with the help of small electric motors, or servos, commonly used by hobbyists in model airplanes.
Built from lightweight materials, the robots are about the size of a human arm orsmaller. They can sense which way is up, but are only as good as their human operators, Choset added.
Sam Stover, a search term manager with the Federal Emergency Management Agency based in Indiana, said snake-type robots would offer greater mobility than equipment currently available, such as cameras attached to extendable roles.
“It just allows us to do something we’ve not been able to do before,” Stover said, “We needed them yesterday.”
He said sniffer dogs are still the best search tool for rescue workers, but that they can only be used effectively when workers have access to damaged buildings.
Stover, among the rescue workers who handled the aftermath (后果) of Hurricane Katrina, said snake robots would have helped rescuers search flooded houses in that disaster.
Choset said the robots may not be ready for use for another five to ten years, depending on funding.
72. Which institution is responsible for the development of Choset’s robots?
A. Robotics Trends.B. Pittsburgh City Council.
C. Carnegie Mellon University. D. Federal Emergency Management Agency.
73. Choset believes that his invention ______.
A.can be attached to an electronic arm B.can be used by hobbyists in model airplanes
C.can find victims more quickly than a sniffer dog
D.can sense its way no better than its operators
74. By saying “We needed them yesterday” (paragraph 7), Stover means that snake-like robots _____.
A.could help handle the aftermath of Hurricane Katrina
B.would have been put to use in past rescue work
C.helped rescuers search flooded houses yesterday
D.were in greater need yesterday than today
75. What is the text mainly about?
A.Snake-like robots used in industries. B.Snake-like robots made to aid in rescues.
C.The development of snake-like robots. D.The working principles of snake-like robots.
