I close my eyes and can still hear her—the little girl with a _\_1__ so strong and powerful we could hear her halfway down the block. She was a（n) _\_2__ peasant who asked for money and _\_3__ gave the only thing she had——her voice. I paused outside a small shop and listened. She brought to my mind the _\_4__ of Little Orphan Annie. I could not understand the words she _\_5___, but her voice begged for ___6___. It stood out from the noises of Arbat Street, pure and impressive, like the chime of a bell. She sang ___7__ an old-style lamp post in the shadow of a building, her arms extended and _\_8__ thrown back. She was small and of unremarkable looks. Her brown hair _\_9__ the bun（发髻) it had been pulled into, and she occasionally reached up to _\_10__ a stray piece from her face. Her clothing I can’t recall. Her voice, on the other hand, is _\_11__ imprinted in my mind.
I asked one of the translators about the girl. Elaina told me that she and hundreds of others like her throughout the _\_12__ Soviet Union add to their families’ income by working on the streets. The children are unable to _\_13__ school, and their parents work fulltime. These children know that the consequence of an _\_14__ day is no food for the table. Similar situations occurred during the Depression（萧条) in the United States, but those American children were _\_15__ shoeshine boys of the _\__16___. This girl was real to me.
When we walked past her I gave her money. It was not out of pity _\_17__ rather admiration. Her smile of _\_18__ did not interrupt her singing. The girl watched us as we walked down the street. I know this because when I looked back she smiled again. We _\_19__ that smile, and I knew I could never forget her courage and _\_20__ strength.

The physicians in a hospital form the center of medical staff. But they could not provide effective medical care to their patients without the help of numerous other medical employees. From the viewpoint of the patients, the nursing staff is particularly important. Nurses are usually in close contact with patients as long as they are in the hospital. A nurse does not study for as many years as a doctor. however, each must be equally dedicated. Caring for sick persons requires a great deal of patience and concern. Most nurses work long days, and they often must work at odd hours or during the night. Under the supervision （监管) of the head nurse, the nursing staff must provide nursing services on a 24-hour basis and attend to patients’ needs. This responsibility continues around the clock, and so nurses must work in shifts. A shift is a period of duty, usually eight in length. The nurses on the ward rotate their shifts. Some take turns working night duty; others work odd shifts. A nurse must always be alert. She can never afford to be careless. This is true in all nursing situation, but it is especially true in the intensive care unit. Patients under intensive care are critically ill, and they must be monitored at all times. The nurses who do intensive care duty have one of the most demanding jobs in the hospital. Serving as a nurse can be a very rewarding job. But it is not an easy one. Not every person is suited to become a nurse. Only very dedicated people have chosen nursing as a profession. 小题1:The nursing staff ________.
A．are central to the medical staff
B．play an important role in caring for patients
C．can work effectively without physicians
D．are always in close contact with the patients小题2:Why don’t nurses study for as many years as doctors？
A．They don’t treat patients for illness and injury.
B．Most nurses work long days.
C．Caring for sick patients requires patience and concern.
D．They are not dedicated.小题3:Nurses work in shifts because ________.
A．they are careless.
B．nursing services must be provided continuously.
C．they work at night from time to time.
D．a shift is usually eight hours long.小题4:What kind of person is suited to become a nurse？
A．A very careful person.

Everyone has good days and bad days. Sometimes, you feel as if you’re on top of the world. But occasionally you feel horrible, and you lose things and you cannot focus on your schoolwork. For more than 20 years, scientists have suggested that high self-esteem （自尊) is the key to success. Now, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something. “Forget about self-esteem,” says Jennifer Crocker, a psychologist （心理学家) at the University of Michigan, US. “It’s not the important thing.” Feeling good Crocker’s advice may sound a bit strange because it is good to feel good about yourself. Studies show that people with high self-esteem are less likely to be depressed, anxious, shy, or lonely than those with low self-esteem. But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person. He believes that violent and wicked people often have the highest self-esteem of all. He also said: “There’s no evidence that kids with high self-esteem do better in school.” Problems All types of people have problems. People with high self-esteem can have big egos （自我) that can make them less likeable to their peers（同龄人), said Kathleen Vohs, a psychology professor at Columbia University. People with high self-esteem tend to think more of themselves, Vohs says. People with low self-esteem are more likely to rely on their friends when they need help. What to do Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something try to learn from the experience. “The best therapy （药方) is to recognize your faults,” Vohs says. “It’s OK to say, ‘I’m not so good at that,’ and then move on.” 小题1:The new research comes to the conclusion that high self-esteem ________.
A．is not important at all
B．has taken on a different meaning
C．may not be the key to success
D．does not help you do better at school小题2:One of the conclusions of the new research is that ________.
A．feeling good about oneself doesn’t mean you lead a happier life
B．people with high esteem usually do not seek other’s help
C．people with high esteem tend to be proud
D．people with low esteem are often more popular小题3:The underlined part “a better person” in the passage probably means a person who is ________.
A．helpful and supportive
B．gentle and modest
C．likable and successful
D．friendly and kind小题4:From the text, we can infer the best therapy mentioned in the last paragraph is mainly for people ________.
A．with high self-esteem
B．with low self-esteem
C．of all kinds
D．who are focusing on building self-esteem

Michael Fish may soon be replaced as a weather forecaster by something truly fishier---the shark（鲨鱼). Research by a British biology student suggests that sharks could be used to predict storms. Lauren Smith, 24, is close to completing her study on shark’s ability to sense pressure. If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather. Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas. She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University. Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001. Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.” “I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand ---- but it certainly opens the way to more research.” It has been discovered that a shark senses pressure using hair cells in its balance system. At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS （Global Positioning System) technology. In Aberdeen, she was able to study the effects of tidal（潮汐的) and temperature changes on dogfish----none of which were harmed. She also used a special lab which can mimic（模拟) oceanic pressure changes caused by weather fronts. She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research. 小题1:The passage is most probably taken from _____.
A．a short-story collection
B．a popular science magazine
C．a research paper
D．a personal diary小题2:What do we learn from the first four paragraph of the passage？
