Annealing is a way of making metal softer by heating it and then letting it cool very slowly. If metal is heated and then cooled very quickly , for example by dipping it in water , it will be very hard but also very brittle(脆)---that is , It will break easily. Metal that has been annealed is soft but does not break as easily . It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly , for a certain length of time. The longer the heated metal takes to cool slowly , the softer it becomes . Annealing can also be used on other materials, such as glass. Annealing can make metal _______________.
| A．hard and tough (韧) | B．hard but brittle |
| C．soft but tough | D．soft and brittle |

Oscar the cat seems to have an unnatural ability for predicting when nursing home patients are going to die, by curling up (蜷伏) next to them during their final hours. His accuracy, observed in 25 cases, has led the staff to call family members once he has chosen someone. It usually means the patient has less than four hours to live. "Many family members take some comfort from it. They appreciate the companionship that the cat provides for their dying loved one," said Dosa, a doctor and assistant professor of medicine at Brown University.
The 2-year-old cat was adopted as a kitten and grew up in a third-floor dementia (痴呆) unit at the Steere House Nursing and Rehabilitation Center, where the facility treats people with Alzheimer's, Parkinson's disease and other illnesses. After about six months, the staff noticed Oscar would make his own rounds, just like the doctors and nurses. He'd smell and observe patients, then sit beside people who would end up dying in a few hours. Dosa said Oscar seems to take his work seriously. "This is not a cat that's friendly to people," he said.
"Oscar is better at predicting death than the people who work here," said Dr. Joan Teno of Brown University, who treats patients at the nursing home and is an expert on care for the terminally ill. She was convinced of Oscar's talent when he made his 13th correct call. While observing one patient, Teno said she noticed the woman wasn't eating, was breathing with difficulty and that her legs had a bluish color, signs that often mean death is near. Oscar wouldn't stay inside the room, though, so Teno thought bis streak was broken. Instead, it turned out the doctor's prediction was roughly 10 hours too early. Sure enough, during the patient's final two hours, nurses told Teno that Oscar joined the woman at her bedside.
Doctors say most of the people who get a visit from the sweet-faced, gray-and-white cat are so ill that they probably don't know he's there, so patients aren't aware he's a predictor of death. Most families are grateful for the advance warning, although one wanted Oscar out of the room while a family member died. When Oscar is put outside, he paces and meows his displeasure.
No one's certain if Oscar's behavior is scientifically significant or points to a cause. Teno wonders if the cat senses mysterious scents or reads something into the behavior of the nurses who raised him. Nursing home staff aren't concerned with explaining Oscar, so long as he gives families a better chance at saying goodbye to the dying. The staff recently gave Oscar a wall sign publicly praising his "sympathetic care."What makes Oscar the cat so special?

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.According to the text, hydrogen-powered buses ________.
| A．can easily be filled up with gas. |
| B．are likely to sell well in the future. |
| C．are mainly used in the United States |
| D．won’t be used in the London Olympics |
What does the underlined word “them” in paragraph 5 refer to?
| A．Japanese companies | B．Hydrogen buses |
| C．The FCX Clarity | D．Filling stations |
Where are hydrogen cars currently available for sale?
| A．In Barcelona | B．In Hamburg | C．In London | D．In Los Angeles |
We can learn from the text that ________.
| A．there are sixty hydrogen filling stations all over the world |
| B．hydrogen vehicles fueled by water will be very expensive |
| C．Honda will mass-produce the FCX Clarity by 2012 |
| D．Honda produced its first hydrogen car in 1989 |
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.”The book Psychology for Medicine is mainly written for ________.
| A．scientists | B．overweight people | C．patients | D．student doctors |
What is the third paragraph mainly about?
| A．The topics of the book. | B．The comments on the book. |
| C．The contributors to the book. | D．The characteristics of the book. |
According to the text, the book Psychology for Medicine _________.
| A．is a bit difficult to understand. |
| B．is mainly about how to lose weight. |
| C．included tips on training football players. |
| D．focuses on the importance of psychology in treatment |
We can infer that the text is a(n) ______.
| A．research report | B．introduction to a book |

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.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. |
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. |
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. |
