Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血壓) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

     Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (緊張) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算術(shù)) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don't judge.

     A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

C
A car that runs on coffee is unveiled（shown to the public for the first time）today but at between 25 and 50 times the cost of running a car on petrol, the invention won’t please any motor industry accountants．
Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for £400 and it was chosen because it looked like the time-traveling DeLorean in the movie Back To The Future．The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules （顆粒）．It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles．
The team calculates the Car-puccino will do three miles per kilo of ground coffee （咖啡粉） — about 56 cups of espressos （濃咖啡） per mile．The journey will use about 70 kilos of ground coffee which, at supermarket prices of between £13 and £26 a kilo depending on brand and quality, will cost between £910 and £1,820, or between 25 and 50 times the £36 cost of petrol for the journey．In total, the trip will cost 11,760 espressos, and the team will have to take ‘coffee breaks’ roughly every 30 to 45 miles to pour in more granules．They will also have to stop about every 60 miles to clean out the ‘coffee filters’ to rid them of the soot and tar which is also generated by the process．So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours．
Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty’s Revenue and Custom haven’t yet worked out how much．
Nick Watson, producer of Bang Goes The Theory, said, “Coffee, like wood or coal, has some carbon content so you can use it as a fuel．The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns．The brand doesn’t matter．” He said the same technology could be used to power a car on other unusual fuels, such as woodchips or nut shells, construction or agricultural waste．
49．Which is the right way to choose the coffee used as fuels to run the Car-puccino?
A．It should be very dry．                B．The stronger, the better．
C．The smaller the granules are, the better．  D．It should be of a certain brand．
50．What can be inferred from the passage?
A．All kinds of materials can be used as fuels．
B．The Car-puccino will be put into the market soon．
C．Nick Watson is the designer of the Car-puccino
D．Much remains to be improved for the Car-puccino．
51．The Car-puccino has its disadvantages EXCEPT that ________．
A．it makes a lot of noise           
B．it runs at a very high cost
C．it has to stop to be refueled very often．       
D．it’s not good enough for long-distance journey
52．How much ground coffee will be used to cover a distance of 126 miles in this car?
A．About 70 kilos    B．About 42 kilos．  C．About 32 kilos    D．About 30 kilos

C
A new age is coming. Call it what you will: the service economy, the information age, the knowledge society. It all translates to a fundamental change in the way we work. Already we’re partly there, the percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more part-time jobs. More people are self-employed. But the range of the economic transformation can’t be measured by numbers alone, because it also is giving rise to important new way of thinking about the nature of work itself. Long-held ideas about jobs and careers, the skills needed to succeed, even the relation between individuals and employers — all these are being challenged.
We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip, would transform our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow’s achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: information and knowledge will become even more valid, and the people who possess it, whether they work in manufacturing or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. If you cast your mind ahead 10 years, information service will be superior. It will be the way you do your job.
66. A characteristic of the new age mentioned in the passage is that        .
A. the service industry mainly relies on females
B. manufacturing industries are steadily increasing
C. more people are in the service industry than before
D. the work in the service industry is more comfortable than that in manufacturing industry
67. Which of the following is true according to the passage?
A. People’s traditional concepts about jobs need changing.
B. The relation between employees and employers is becoming tense.
C. More women than men are in the work force.
D. Part-time jobs are more welcome than full-time jobs.
68. By mentioning the invention of “the chip”, the author means to say that       .
A. we haven’t paid enough attention to the importance of high technology
B. the chip is the most important invention today
C. the power of science and technology is beyond our imagination
D. it’s a great challenge to apply new inventions to our life
69. We may draw a conclusion from the passage that        .
A. information will play a greater role in people’s work and daily life in the future
B. we can foresee the future if technology develops fast enough
C. the ability of performing routine tasks gives you an advantage in work
D. robots will replace people to do all the work both in manufacturing and service industries
70. The author’s attitude to the coming age is        .
A. doubtful         B. enthusiastic           C. satisfied        D. Uncertain

C
A long-awaited final report from the Food and Drug Administration (FDA) concludes that foods from healthy cloned animals and their offspring(后代) are as safe as those from ordinary animals, effectively removing the last US regulatory(監(jiān)管的) barrier to the marketing of meat and milk from cloned cattle, pigs and goats.
The 968-page final report, not yet released but obtained by The Washington Post, finds no evidence to support people’s concerns that food from clones may have hidden risks.
But, recognizing that a majority of consumers are wary of food from clones—and that cloning could damage the good image of American milk and meat—the report includes hundreds of pages of raw(原始的) data so that others can see how it came to its conclusions.
The report also admits that human health concerns are not the only subject raised by the coming-out of cloned farm animals.
“Moral, religious and ethical concerns have been raised,” the agency notes in a document accompanying the report. But the report is “exactly a science-based evaluation.” It reports, because the agency is not authorized by law to consider those subjects.
In practice, it will be years before foods from clones make their way to store shelves in large quantities, in part because the clones themselves are too valuable to kill for meat or milk. Instead, the expensive animals—replicas(復(fù)制品) of some of the finest farm animals ever born—will be used firstly as breeding stock to create what supporters say will be a new generation of superior farm animals.
When food from those animals hits the market, the public may yet have its say. FDA officials have said they do not expect to require food from clones to be labeled as such, but they may allow foods from ordinary animals to be labeled as not from clones.
64.   What can we infer from the first paragraph?
A.    FDA has waited for a long time to get this final report.
B.    Products from cloned animals have been put into the market before.
C.    People are having the products from cloned animals safely.
D.    There have been once opposite opinions against cloned products.
65.   What does the underlined word “wary” mean?
A. Disappointed.           B. Careful.         C. Fond.                                 D. Proud.
66.   It will be a few years before foods from clones come into the market, partly because _____.
A.    people have little knowledge of the cloned animals
B.    supporters can’t give powerful evidence to support that
C.    the few cloned animals will first be used to create superior animals
D.    they are a new generation for the customers and are too valuable for the customers
67.   What can we conclude from the passage?
A.    FDA officials encourage people to eat more food from clones.
B.    FDA officials think the food from clones will sell better than ordinary food.
C.    People only worry about the health problems when it comes to foods from the clones.
D.    All the foods will not have detailed labels on them.
