For medical students, real experience begins not in a classroom but at a teaching hospital. These doctors in training are guided. But sometimes accidents happen and the students get injured.
For example, they might stick themselves with a needle while treating patients. Such needle sticks are common. But a recent study found that medical students often fail to report them. Failing to report an injury like this can be dangerous if a patient, or a medical worker, has an infectious disease.
Researchers at Johns Hopkins University in Baltimore, Maryland, did the study, which involved a survey answered by almost 700 surgeons in training in the United States.
Almost 60% said they had suffered needle stick injuries when they were in medical school. Many said they were stuck more than once. Yet nearly half of those whose most recent incident happened in school did not report it to a health office. If they had, they would have been tested to see if they needed treatment to prevent an infection like HIV or hepatitis.
Most known cases of HIV or hepatitis are reported, but other possible infections often are not. Martin Makary, the lead author of the study, says medical students who are stuck put themselves and others in danger from infectious diseases.
Doctor Makary said, "A needle that goes through the skin needs to be as sharp as possible.” Doctors in training may have to do hundreds of stitches (缝线) in some cases to close the skin after an operation.
Doctor Makary said, “I support using blunt tip needles which are considered safer. This needle is still sharp enough to go through body tissue, but it does have a blunt tip, so that if it accidentally goes into my finger, it's much less likely to hurt me."
How common are needle sticks among health care workers? An estimated 600,000 to 800,000 of these and similar injuries are reported each year in the United States. But Doctor Makary says the real number may be much higher.
The study advises doctors to protect their hands by wearing two sets of gloves. It also urges hospitals to establish a special telephone number for medical workers and students to call if they are injured. The idea is for hospitals to send a clear message that there is no reason not to report this kind of accident.It is dangerous for medical students not to report needle stick injuries because _________.

A glass a day keeps obesity at bay. Alcohol has always been thought to cause weight gain because of its high sugar content, but new research suggests a glass a day could form part of a diet. Looking at past studies they found that, while heavy drinkers do put on weight, those who drink in moderation can actually lose weight.
A spokesman for the research team at Navarro University in Spain says, “Light to moderate alcohol intake, especially of wine, may be more likely to protect against, rather than promote, weight gain”. The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions, particularly that current data do not clearly indicate if moderate drinking increases weight.
Boston University’s Dr. Harvey Finkel found that the biologic mechanisms (生物学机制) relating alcohol to changes in body weight are not properly understood. His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes(糖尿病)，which relate to increasing obesity. Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.
The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat, and that this process could explain the differences in its effects from those of other foods. They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks, taking into consideration drinking patterns and including the past tendency of participants to gain weight.
For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese. What’s more, a study three years ago suggested that resveratrol, a compound present in grapes and red wine, destroys fat cells.The passage is mainly for those ______.
| A．who produce wine |
| B．who are eager to lose weight |
| C．who go on a diet |
| D．who have a drinking habit |
The underlined phrase “in moderation” in the first paragraph means ______.
| A．properly | B．carefully |
| C．excitedly | D．frequently |
Why has alcohol been thought to cause weight gain?
| A．Because its calories are stored in fat. |
| B．Because it is rich in sugar. |
| C．Because it changes drinking patterns. |
| D．Because it increases the risk of diabetes. |
What can we learn from the passage?
| A．The specific roles of different types of alcoholic drinks are very clear. |
| B．Resveratrol is proved to increase the risk of becoming fat. |
| C．The research found moderate drinking has a strong protective effect. |
| D．Current data clearly show that moderate drinking increases weight. |
What is most likely to be discussed in the paragraph that follows?
| A．How to do some easy experiments. |

| C．How to make wine in a healthy way. |
| D．How to reduce the calories contained in wine. |
Sina Weibo, one of the country’s most popular micro-blogging sites, has launched a paid service. For a 10 yuan ($ l.57) monthly fee, users get a membership on their Sina Weibo accounts.
According to Xu Yuanyuan, a member of the marketing team at Sina, the move is to guarantee a more convenient and safer environment for users. But despite the company’s efforts to increase income, it seems that most of its 300 million users still prefer the free version.
The premium membership (高级会员) plans ,announced by the company on Monday, brought about negative comments from its users .
“The current service is good enough for me”, said a Beijing-based micro-blogger. “I don’t really need those value-added services and it might be a waste of money. I might consider paying for it if some more features are added.”
Dong Xu, an analyst with consulting firm Analysis International, said that Sina shouldn’t expect a great increase in income brought by the new services. The free services are enough for most users, Dong said. “The company has been making attempts at different profit models since last year. A potential source of income could be gaming. Games and advertisements are so far the two biggest sources of income.” she said.
Other micro-blogging service providers have not yet followed suit. Fang Gang, vice-president of rival Sohu, said via e-mail on Tuesday that Sohu’s micro-blogging service will never charge users. “It’s good news for us. Users can come to our website if they have to pay for services (at Sina).” Fang said.
Most of Sina Weibo’s users .
| A．aren’t satisfied with its free version |
| B．show no interest in its paid services |

What’s Dong Xu’s attitude towards Sina Weibo’s new services increasing income?
| A．Negative. | B．Confident . |
| C．Indifferent. | D．Positive . |
Why did Fang Gang consider Sina Weibo’s charging its users good news?
| A．Because Sina will make more money. |
| B．Because Sina will lose the whole Weibo market. |
| C．Because Sohu will attract more users. |
| D．Because Sohu will offer free services. |
What can be inferred from the text?
| A．Most of Weibo websites will charge their users. |

The chimp didn’t feel well. She fell over, ignoring the other wild chimps. Finally, the sick chimp crawled over to a bush, picked some leaves and swallowed them. By the next afternoon, the chimp was as good as new!
Biologists watching the chimp were surprised. Somehow, the plant had cured the chimp! Did the chimp know the plant would make her feel better? Or was it just a lucky accident?
Many scientists don’t think it has anything to do with luck. They’re discovering that some animals seem to use plants to cure themselves. And these animals are leading scientists to new plants that could cure humans!
Dr. Richard Wrangham, an anthropologist at Harvard University, agrees that animals may know something we don’t know about forest plants.
Wrangham got to know chimps and their diets while studying them for three years in Tanzania. “You must know a lot about an animal’s feeding habits to know what it doesn’t consider food,” Wrangham explains. Every morning, he saw that most chimps ate fruit near their nests. Later on, they ate on leaves.
When he noticed chimps eating the leaves of a plant they usually ignored, Wrangham thought something interesting was going on---especially when he saw that they’d sometimes walk for 20 minutes to find the plant. Another strange thing that caught his eye was how they ate the bitter leaves.
“They swallowed the leaves whole,” explains Wrangham, noting that chimps usually chew their food well. “They seemed to rub（摩擦）the leaves around the roofs of their mouths. They closed their eyes, wrinkled their noses and swallowed slowly. ”
Wrangham wondered what could be so good about something tasting so bad. He had a chemist analyze the leaves. He discovered that the leaves contain a red oil that kills different viruses（病毒）. Later tests showed that the oil might even fight cancer and the AIDS virus!
Why don’t the chimps chew the leaves? “Rubbing the leaves between the tongue and the inside of the mouth might allow the chemicals to enter the bloodstream directly,” he suggests, “instead of going to the stomach, where they might get destroyed by acids. The chimps seem to know what they’re doing.”We can learn from the passage that _________.
| A．chemicals in plants help cure animals |
| B．chimps cure themselves by chewing plants |
| C．scientists live with chimps to study their diets |
| D．Dr. Wrangham knows a lot about forest plants |
How can Dr. Wrangham tell which plants are medicine for chimps?
| A．By talking with the biologists. |
| B．By analyzing the chimps’ favorite food. |
| C．By studying the chimps’ feeding habits. |
| D．By comparing other scientists’ discoveries. |
The author wrote the passage to ___________.
| A．present a finding | B．test a theory |
| C．provide a solution | D．describe an experiment |
What does the passage mainly talk about?
| A．Forest plants. | B．Animal doctors. |
| C．Chimp’s diets. | D．A cure for cancer. |
It does not matter who wins. We are told that from day one. Usually, that statement is followed by some remark about being a loser. If we do not care who wins, then why do we compete? Fun, experience, the chance to meet new people --- these are the reasons we try to outdo each other.
People will compete over anything. Every Christmas, my neighbors and I have a little Christmas light competition. It is heaven for the electric company, but I think we give Will Rogers Airport a scare. It is bright enough to land a plane in our front yards. I admit that last year my neighbors won, but only because they bought every strand of lights Wal-Mart had before I could get there.
Personal competitions are great, but we get a little carried away. I cannot stand to see coaches shout at kids playing sports. Who cares if someone messes up and the other team advances?
I’m tired of people competing just to win. It happens not only in sports, but in music competitions, too. People auditioning（试音）for chair placement in certain bands can get really unfriendly. This year I did not audition for a certain band, but I went to auditions anyway. This was the first time I actually had the opportunity to comprehend the whole picture.
Other times I’ve been the person who was nervous and anxious. This time, I sat back and observed everyone else. I came to the realization that the people who aren’t so good are terrified of the good people, and the good people are scared stiff that the bad people have taken lessons and can now show them up. Unless a person is on the outside looking in, I don’t think anyone realizes this.
Maybe competing is human nature, but we shouldn’t let it influence our judgment. Being disrespectful to opponents（对手）, letting competition become our life, and becoming so involved that we close ourselves off from friends and family is not the meaning of competition.
A little competition is healthy, so it shouldn’t hurt anyone. If it does, someone somewhere needs to back off, find the good thing hidden inside, and try it again. Winning isn’t everything, and losing isn’t the end of the world.The author mentions his competition with his neighbors to __________.
| A．make excuses for his failure |
| B．express his concern about the airport |
| C．imply his neighbor cheated in the competition |
| D．show people really care about the result of competition |
The underlined word “this” in Paragraph 5 refers to ________.
| A．the rules of competition |
| B．competitors’ effort to win |
| C．the influence of competition on life |
| D．the negative attitude to competition |
From the passage, we can learn that _______.
| A．the author failed the audition |
| B．competitors may be unfriendly to each other |
| C．it is coaches who always mess up the match |
| D．those who observe opponents calmly always win |
Which of the following opinions does the author probably accept?
| A．Competition for the job is fierce. |
| B．Winning or losing is none of people’s concern. |
| C．Competition is healthy, but it can get out of hand. |
| D．The disadvantages of competition outweigh the benefits. |
My name is Pablo. I think I’m a lucky guy. I have a good family, and we live in a nice neighborhood in Puerto Vallarta, Mexico. People travel here from many countries for their vacations. We have beautiful beaches, hotels, restaurants, shopping and sports.
However, in my beautiful hometown, there are also very poor neighborhoods. These areas are crowded and have a lot of crime. Life is terrible for many of the children in these areas. Some don’t really have a childhood because they’re homeless and live on the streets. They don’t have education. They don’t have enough food. Many use drugs or have diseases or mental problems.
Last year, I came back to Puerto Vallarta from my university in Mexico City. I spent one year as a volunteer with an organization called Outreach International. They have several programs. I volunteered for one program to help street children.
I worked in a home for street children (all boys, at this one). At this home, the boys have a place to sleep and three meals daily. The home keeps the boys off the streets. It shows them another way of life. As a volunteer, I helped to prepare meals. I taught games---such as basketball, football and art. I helped the kids with their homework. These kids can be fun. They have a lot of energy, but they’re also really tough. Their hardships on the streets make them strong and not always “sweet little children.”
At this boys’ home, I met two other volunteers---Brian from Canada and Greg from Australia. In many ways, we were very similar. We were the same age, came from good homes and had a good education. They were both college students, like me. We became very good friends. Now, we email each other.
It was the best---and most difficult---year of my life. I learned a lot that year.What do we learn about the author?
