There are two methods by which hydrogen (氢) can be used to power cars. The first way is to use hydrogen to drive the engine, in much the same way as many cars use gas. The second method is to use the reaction of hydrogen with oxygen in a battery, making the car a kind of electric one.

The dream of producing hydrogen in the car while driving along by electrolyzing (电解)water is a long way off, so we are still at the period of batteries and filling the tank with hydrogen gas. This is the difficulty for potential car users and producers. There are only sixteen hydrogen filling stations in Los Angeles and none in 99% of other cities worldwide.

Indeed, some of the big name automobile producers have pulled out of the race to put the first practical hydrogen car on the streets. Ford and GM have announced that they are pulling out in America and so has Renault in France.

However, the Japanese companies are pressing on. In fact, Honda introduced its first hydrogen fuel cell car in 1999. They are now producing second generation hydrogen car known as the FCX Clarity. Guess where they are available for sale? In only one city because of its filling stations.

Honda thinks that they could go into full-scale production of the FCX Clarity by 2020 if the world is prepared for them by then.

Then there are hydrogen-powered buses in several European cities including Amsterdam, Barcelona, Hamburg, London, Luxembourg and Madrid. Lotus, the makers of London taxis, have announced that they propose to manufacture hydrogen-powered taxis in time for the London Olympics.

So, the hydrogen vehicle is out there and the numbers will be growing fairly soon. The buses go back to their bus station, where an electrolyzing machine changes water into fuel for them to fill up on and the same will be the case for many of London’s taxis.

Unfortunately, getting fuel is not the only difficulty for the average motorist, a number of these vehicles cost about $300,000 each.

Why does the rate of heart attacks increase during the World Cup football finals? How can we help an overweight patient to lose weight? They’re just some of the topics covered in a new book by University of Sussex academics, which is helping student doctors to consider the importance of psychology in medical practice.

Psychology for Medicine is the first textbook of its kind, providing medical trainees and new doctors with all the relevant psychological knowledge they need. Previously, students had to refer to many different books for the relevant psychology.

The book, by Sussex psychologists Dr. Sussex Ayers and Dr. Richard de Visser, has been well received by fellow academics and medical doctors and was finished with the help of the students and staff of the Brighton and Sussex Medical School. The students proofread(校对) the chapters, provided ideas for the content and even modeled for the photographs. The book provides a solid grounding in psychological study relevant to medicine, along with practical tips and advice for practice. One student, Simon Hall, drew cartoons for the book.

The study psychology is important for doctors for a number of reasons. Psychological and physical symptoms are highly related. Up to a third of patients will have psychological disorders, while physical causes are usually only found in around 15 per cent of people’s symptoms. In treatment, a lot of the effect drugs can be due to patients believing they will recover rather than the drug itself.

Dr. Ayers says, “The important thing about this book is that it’s applied science --- it shows why psychology is important to medicine and how we should use it. The book’s presentation is really important. It’s not just lots of theory, but full of tips and advice so that students can take what they learn in the classroom and apply it to real-life situations.”

Being less than perfectly well-dressed in a business setting can result in a feeling of discomfort. And the sad truth is that “clothing mismatches” on the job can ruin the day of the person who is wearing the inappropriate attire(着装)—and the people with whom he or she works.

Offices vary when it comes to dress codes. Some businesses have very strict standards for office attire, while others maintain a more relaxed attitude. However, it is always important to remember that no matter what your company’s attitude is, you are working in a business environment and you should dress properly. Certain items may be more appropriate for evening wear than for a business meeting, just as shorts and a T-shirt are better suited for the beach than for an office environment. Your attire should reflect both your environment and your position. A senior president has a different image to maintain than that of a secretary. Like it or not, you will be judged by your appearance.

This is never more apparent than on “dress-down days”, when what you wear can say more about you than any business suit ever could. In fact, people will pay more attention to what you wear on dress-down days than on “business professional ” days. Thus, when dressing in “business casual” clothes, try to put some good taste into your choices, recognize that the “real” definition of business casual is to dress just one notch(等级) down from what you would normally wear on business-professional attire days.

Remember, there are borders between your career and our social life. You should dress one way for play and another way when you mean business. Always ask yourself where you are going and how other people will be dressed when you get there. Is the final destination the opera, the beach, or the office? Dress properly and you will discover the truth in the principle that clothes make the man—and the woman. When you’re in doubt, it’s safe to be on the side of dressing slightly more traditionally than the situation demands.

60. What is the passage mainly about?

   A. How to dress properly in a business setting.   

   B. How to choose appropriate attire.

   C. Appropriate attire will make a big difference  

   D. Improper dress will make a person uncomfortable.

61. Which statement best describes “dress-down days”?

   A. You can wear whatever you like.  

   B. People are usually more careful about dressing.

   C. We can’t judge a person’s taste by his clothes.

   D. People’s clothes don’t receive much attention.

62. Which of the following is NOT the rule offered in the passage about business dress?

   A. Dress a bit traditionally if you are not sure about proper dress for an occasion.

   B. Think about how others will dress if invited to a dinner.

   C. For a business meeting and a concert, you should dress differently.

   D. Ask others for advice when you are not sure about what to dress.

                      

  As a young girl, Margaret “Mattie” Knight never played with dolls, preferring to make toys for her brothers instead. In 1849, Knight went to work in a cotton factory where she witnessed a “shuttle,” a device that carries thread back and forth across a textile loom(纺布机), fly off the machine when the thread broke, striking and killing a young boy about her own age.

  The 12-year-old Knight developed a safety mechanism that made it impossible for a shuttle to leave the loom. The design was so effective, soon virtually every new power loom carried her invention, saving countless workers from injury or death. Being so young, she didn’t bother to patent the device, so she never received payment.
  Knight wouldn’t make the same mistake later in life when she invented a machine that could produce flat-bottomed paper bags. Knight had built a small wooden model in her home, but she needed a metal version to show it could hold up to the stress of mass production. So she hired Charles Annan to make the full-sized machine for her, only to have him try to claim the patent for himself. When Knight sued(起诉), Annan’s argument was that the design had to be his, because no woman could possibly understand the complex mechanics. Knight proved him wrong when she brought back her wooden prototype and explained how every part worked. She won the case in 1871, making her the second woman to hold an American patent. Over a hundred years later, her design is still used as the basis for many modern flat-bottom bag machines.

  But that wasn’t the last the world heard of Mattie Knight. During her lifetime, she made about 90 inventions and received 26 patents, becoming one of the most productive female inventors of the 19th century.

A. It is still used today.       B. It brought her great profit.

C. It was made when he was 20.   D. It reduced injuries at textile plants.

58. Knight sued Charles Annan because he _______.

A. stole the wooden model for the machine she invented.

B. failed to make the full-sized machine for her

C. tried to patent her invention for himself

D. kept the metal version for himself

59. What would be the best title for the text?

A. Mattie Knight’s fight for her patent    B. A great woman in the 19th century
