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 (縫線) 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.
【小題1】It is dangerous for medical students not to report needle stick injuries because _________.
A.they don’t know how to treat themselves. |
B.they may meet more needle sticks |
C.it may cause some diseases |
D.it may make patients sad. |

US military is attempting to develop a new style “insect robot” to replace the human soldier to go wherever he can’t. The greatest trouble this project has fallen across is how to enable the robot to fly freely like an insect, said an official of the Pentagon(五角大樓).
The Pentagon is seeking for the cooperation with scientists in hope of developing a new technique by which people can control the insect’s flight direction and pass on the information its eyes or other organs catch through the equipment set in its body, the official said.
It is thus designed that a tiny controlling chip will be equipped in an insect’s body when it is in chrysalis(蛹). As the insect grows, the cut made when fixing in the chip will be recovered. The chip will exist in forever. Scientists believe this won’t influence the insect, sound growth or the functions of internal organs.
The terminal target of the project is to set up a global system, in which the insect robots will be stationed in all parts of the world and stick to their posts till a new instruction is received. At that time the military can receive from all over the world clear image information within about 5 meters of the insects and that of a special target within 100 meters.
Years ago, Defense Advanced Research Projects Agency of US DOD(國防部) spent $3,000,000 carrying out a plan for training bees to detect landmines. But, no new progress has so far been made.
“According to the scientists, there is still enormous difficulty in technology in turning it into reality, such as the insects reproduction(繁殖), their adaptation to the surroundings and temperature and so on. However, this project is really challenging. If successful, it is equal to making countless small drone(無人機),”said the official of DOD.
【小題1】According to the description of the passage, what is an insect robot like?
A.An insect made of a certain metal. |
B.A robot looking like an insect. |
C.An insect with a chip in its body. |
D.A tiny flying robot. |
A.There must be a controlling chip well connected with the insect’s brain. |
B.The insect’s eyes and other organs must be replaced by some special equipment. |
C.All the insect’s concerned organs must be controlled by a chip. |
D.The insect must be so well trained as to make full use of its organs. |
A.have a clear picture of almost every part of the world |
B.have insect robots from all over the world |
C.see clearly the things within 10 to 100 meters |
D.get many insects which obey their orders |
A.They can’t keep sound growth of the insects. |
B.They can’t ensure the insects to produce their young. |
C.They can’t fix a chip in an insect. |
D.They can’t make sure the internal organs function well. |
A.Leading. | B.Vital. | C.Moral. | D.Final. |

Of all the websites, one that has attracted attention recently is myspace.com. Most of this attention has come from the media and tells every reason why the website should be shut down. The danger of internet predators(竊掠者) is indeed a tough reality, but shutting down the site is not the answer. If myspace.com were shut down, another site would quickly take its place. Therefore, the right way is to teach teens how to use the site safely and educate them about who may be predators and how to avoid them.
The key to staying safe on the Internet is to make sure that your profile(個人資料) is secure. The simplest way is to change the privacy setting on your profile to “private”, which protects your information so that only the people on your friend list can view it. Although this is effective, it is not perfect. Predators can find ways to view your profile if they really want to, whether through hacking(非法侵入) in or figuring out their way onto your friend list. Thus, you should never post too much personal information. Some people actually post their home and school addresses, date of birth, and other personal information, often letting predators know exactly where they will be and when. The safest information is your first name and province. Anything more is basically inviting a predator into your life.
Another big problem is photos. I suggest completely skipping photos and never posting a photo of a friend online without asking permission.
Most importantly, never, under any circumstances, agree to a real-life meeting with anyone you meet online. No matter how well you think you know this person, there are no guarantees that they have told the truth. But you could feel free to chat with people you meet on the site, but just remember that not everyone is who they say they are. Hopefully, the next time you edit your profile, you’ll be more informed about the dangers of Internet predators and take the steps to defend yourself.
Lastly, do not send money to anyone you meet online. A common scam among Internet criminals is to request to pay for “expensive Internet charges” or “unreasonable Internet cafe fees”. While it is indeed true that many countries in Eastern Europe, Asia, Africa and South America do not yet have Internet service readily available in all cities and towns, a sincere friend from one of these countries will be more than happy to pay their own Internet charges. Never, under any circumstances, should you send money to a stranger from another country(or within your own country for that matter) who claims monetary assistance is required to continue their contact with you.
【小題1】Kids can avoid web predators successfully by________.
A.a(chǎn)ttracting more public attention |
B.shutting down the “myspace.com” |
C.learning different ways to try other sites |
D.recognizing and getting away from them |
A.everybody you meet online isn’t honest and reliable |
B.it is not acceptable to post a photo of a friend online |
C.it is not safe to chat with grown-ups on the website |
D.only you and your friends can view your personal profile |
A.A thing that you can have two choices. |
B.An unpleasant task that tests one’s ability. |
C.A possibility of something happening. |
D.An illegal plan for making money. |
A.Personal Safety. | B.Web Safety for Teens. |
C.Web Hackers in the past. | D.Predators’ Tricks. |

Retail therapy(購物療法)has long been considered as a good way to let off stress. Now, US scientists have discovered not only does retail therapy exist,but that it could be caused by an individual's fear of sudden death.
Researchers found materialistic people thought terrorism and war more stressful than others.
Psychologists believe the rise of materialism around the world and its treatment effect on extreme stress might be a response to fear of death caused by acts of terrorism, disease and natural disasters.
The scientists from Michigan State University said people with possession obsessions(妄想)often have lower self-esteem than others so are more likely to shop as the result of severe psychological suffering.
Ayalla Ruvio,a business professor studying people's shopping habits while rockets fell in Israel, said, "When the going gets tough, the materialistic people go shopping. This stress spending is likely to produce even greater stress and lower well-being. Essentially, materialism appears to make bad events even worse.
Dr Ruvio led a two-part study of Israeli citizens living in a town that came under extreme rocket attacks for about six months in 2007. She compared 139 residents of the southern town with 170 from another town that was not under attack to see how their symptoms of post-traumatic stress and shopping habits varied. Dr Ruvio found that, when faced with a deadly threat, those who are highly materialistic suffered much higher levels of stress,while their tendency to shop was increased.
Dr Ruvio said, "The relationship between materialism and stress may be more harmful than commonly thought.”
The second stage of their research surveyed 855 Americans about their materialistic nature and fear of death. They found shopping was used to relieve feelings of stress and anxiety about death but this was in response to fear of a variety of life-threatening events like car accidents, criminal attacks and natural disasters.
【小題1】Which of the following opinion is NOT right according to the text?
A.Terrorism is believed to easily cause the rise of materialism. |
B.The materialistic find terrorism and war more stressful than others. |
C.The scientists think possession obsessions help people get self-respect. |
D.The scientists think people with possession obsessions suffer a lot mentally. |
A.They enjoy the special shopping culture. |
B.The stresses they face are usually deadly. |
C.They are in different situation in terms of war. |
D.They are usually active participants for researchers. |
A.Impulsive spending does good to people's health. |
B.Shopping can't lower one's stress as it is expected. |
C.Faced with great stress, people feel hopeless for life. |
D.Faced with threat,people's wish to shop will decrease. |
A.①②③ | B.②③④ | C.①②④ | D.①③④ |
A.Greater stress can lead to shopping. |
B.Greater stress can cause a lot of diseases |
C.Shopping is very important in people's life. |

One reaction to all the concern about tropical deforestation(毀林) is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"
The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.
Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
【小題1】The underlined word "synthetics" probably means_________.
A.natural rubber | B.tropical materials |
C.man-made material | D.commercial rubber |
A.The forests are losing their function in turning carbon dioxide into oxygen. |
B.Many of our daily uses are related to the tropical forests. |
C.Tropical plants can be used to make industrial products. |
D.High carbon dioxide levels will make the earth warmer. |
A.puzzling | B.cold | C.supporting | D.opposed |
A.Tropical Forests | B.The Value of Tropical Forests |
C.Tropical Forests and Our Life | D.The Greenhouse Effects |

BEIJING—As China scrambles to respond to the choking smog that has blanketed Beijing in recent weeks, authorities in several major cities are experimenting with carbon trading platforms. The schemes are one effort to get control over greenhouse gases in an economy still hungry for cheap energy.
It has been a persistent concern in recent years, but the spiking pollution levels in January are sparking a public outcry.
Emissions from coal-fired electricity plants and busy factories are part of the problem that officials hope to get control over through carbon trading platforms. Seven cities are expected to open carbon markets later this year, including Tianjin.
“The government has decided to start with programs because the carbon trading is something new to China,” said David Tang, secretary of the board of the Tianjin Carbon Exchange. “So we want to have a number of programs to explore the use of the market.” said Tang.
China wants to launch a national carbon trading program by 2016. If it is successful, analysts say, the program would be one of the largest in the world and would help the country meet its target of cutting carbon dioxide emissions by 45 percent within seven years.
The platforms allow companies to earn credits for lowering greenhouse gas emissions, which can then be traded. If it works, it would encourage for-profit businesses to invest in green technology.
As public concern builds pressure for the government to find a solution, Wu Changhua, greater China director of the Climate Group, says there is a broad shift under way in how Chinese weigh their quality of life.
China has long put economic growth ahead of environmental concerns, making it the world’s biggest polluter. Carbon trading supporters hope that the markets could be one way to curb pollution and keep the economy growing.
【小題1】Which of the following is TRUE about carbon trading platforms?
A.They are used to trade various resources. |
B.They caused the choking smog in China. |
C.They have been in existence for many years in China. |
D.The choking smog may promote their development. |
A.to make blanket | B.to cover something | C.to make something empty | D.to be like a blanket |
A.unknown | B.indifferent | C.optimistic | D.pessimistic |
A.China will have built a national carbon trading program by 2016. |
B.Chinese have lived a life of high quality in all aspects. |
C.The markets could slow the development of economy. |
D.Standards of life will be changed in China. |
A.The choking smoke in China. | B.The urge for carbon trading platforms. |
C.Greenhouse gases. | D.The world’s biggest polluter. |

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to?The good news is that we can, In fact, we are swimming in it—literally.
Hydrogen is one of the building blocks of the universe ,Our own sun is basically ,a big ,dense cloud of the stuff ,And hydrogen can be used to create electricity for power ,heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time , It does not exist as a material on its own ,but is always part of something else, So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas , As oil will start to run out in around the year 2030.,it makes sense to produce as much hydrogen as possible as soon as we can ,But natural gas supplies will also begin to run out soon after, Another source is needed.
Researchers are now using electricity to make water into hydrogen ,Companies are working on the problem in their own areas ,The first commercial hydrogen ,”fuel cells”for computers and mobile phones have already come on to the market ,Auto companies have also invested over US $2billion in the production of hydrogen fuelled cars
Thd nations of a hydrogen fuelled planet would not fight over evergy recourses, There would be a great reduction in pollution ,The only by-product of creating hydrogen is pure drinking water—something that is very scarce in many parts of the world ,But that is not where the good news ends, Once the costs of producing hydrogen have been brought down ,it will possibly provide power for a third of the Earth ‘s population that has no electricity.
And electricity creates wealth, In South A frica over the last decade there has been a large programme of electrification, Thanks to the programme , people do not have to spend their days looking firewood to burn for heat, And with electric light , they can work long into the night.
Some scientists see radical changes in the way the human race co-operates, Hydrogen creates clectricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it ,Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web”, which it supplies with electricity ,A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car, Hydrogen could be the first democratic energy source.
Like all dreams of the future, it seems very far away, But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to edn oil dependency and spend more time and money on hydrogen resource, So maybe the threat of war is not a completely bad thing for the future of the human race.
【小題1】What does the underlined word “it”in the last but one paragraph refer to?
A.wealth | B.hydrogen | C.electricity | D.fuel |
A.It has by-products |
B.It has to be separated from other materials |
C.It will make energy too cheap |
D.It is too far away from us |
A.To tell us that we produce energy while using hydrogen power |
B.To tell us that hydrogen power does not produce pollution |
C.To show hydrogen power can stop war |
D.To show hydrogen power is cheap |

The fourth round of heavy smog to hit Beijing in four weeks has sent more people to the hospital with respiratory (呼吸的) illnesses and led to calls for laws to control the pollution.
Pan Shiyi, a celebrity, said he is planning to propose a Clean Air Act to the local government. As a representative to the Beijing Municipal People's Congress, he started an online survey at 9:20 a.m. Within three hours, more than 25,000 web users, or 99 percent of total respondents (應(yīng)答者) , welcomed his proposal.
They have good reasons to stand alongside Pan. The latest round of haze(霧霾)reduced visibility to under 500 meters in many parts of the city. The smog has also led to a great increase in respiratory illnesses, particularly among children and the elderly. Anxious parents and doctors almost all blame the smoggy air for the illnesses. Though most schoolchildren are home for the winter holidays, the bad air can easily move indoors. Besides, ordinary medical masks fail to provide enough protection, so some people have turned to gas masks.
The causes of the frightening smog are rather mysterious, though experts blame too much emissions (排放) and the mountains around Beijing that trap pollution in winter, unless there is enough wind to clear it away. Some critics blamed China’s top two oil firms, China National Petroleum Corp and China Petrochemical Corporation, saying the companies’ outdated production technologies produce large quantities of high-polluting gas fuel.[來源:學(xué)|科|網(wǎng)]
Meanwhile, some Beijingers have moved their brainstorming discussion to computers. If Pan’s proposal for a Clean Air Act is adopted, netizens say the new law should include items providing for “car-free days” in times of smog, higher standards for vehicle fuel, stricter limit to industrial and engine gas emissions, and more effective protection for the public.
Beijing is not the only city that has ever lost the blue sky. Five days of thick fog caused thousands of deaths in Britain in December 1952, urging the government to pass the first Clean Air Act in 1956, which introduced smokeless zones and cleaner fuels to reduce pollution. That may provide some experience for Beijing to refer to.
【小題1】Why did Pan Shiyi started an online survey?
A.To know the public’s opinions on pollution |
B.To tell people the danger of the smoggy weather |
C.To call on people to support his proposal |
D.To collect supporting evidence for his proposal |
A.People are clear about the causes of the smoggy weather. |
B.Children staying indoors will not get respiratory illnesses. |
C.Smog is worse for people with lower resistance to diseases. |
D.Masks can give people protection against the smoggy weather. |
A.suggest Beijing should learn from other countries |
B.let people know many places have this problem |
C.tell people the situation in Britain is worse |
D.call on the government to pass Britain’s Clean Air Act |
A.The Use of Gas masks and Engines |
B.Beijingers Call for Clean Air Act |
C.Effective Protection for Blue Sky |

Electrical devices(儀器)could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine
that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers(起搏器). It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version shou1d be ready in one year.
The developers hope the device will one day help developing countries. Near1y twenty five
percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from wa1king.The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.
【小題1】 The second paragraph mainly talks about .
A.who developed the device |
B.how the device works |
C.several possible uses for the devices |
D.how much electricity the device can produce |
A.produces power without adding more loads to the walker |
B.can produce more power in a much shorter time |
C.needs to be equipped with a battery |
D.can help the walker wa1k faster |
A.help housewives operate the washing machine |
B.make it much easier for us to go online |
C.produce more electricity than that invented by Larry Rome |
D.be applied in medicine to operate heart pacemakers |
