    Daylight-powered germ-killing equipment(杀菌设备)may someday help protect health workers from deadly virus like Ebola virus. That is a finding from a study published in the journal Science Advances.

    Study organizers say they've developed membranes(薄膜)that produce very small amounts of hydrogen peroxide(过氧化氢)when left in daylight. Membranes are thin plastic, structures that can serve as barriers. They let some things pass through, but other things art blocked. Hydrogen peroxide, a liquid sold in drug stores, works as a disinfectant(杀菌剂).

    Nearly 500 health workers were infected and died in 2014 when Ebola spread through parts of West Africa. Caregivers wear full-body protective suits when they come into contact with patients with infectious diseases. But the process of removing the suits is a time when infection can spread if the surface is covered with virus. “If there's any live bacteria or virus on the surface, it's still transmissible and could cause infection,” said Gang Sun of the University of California. He is one of the researchers that worked to develop membranes that could cover the outside of protective equipment.

    When the chemical molecules(分子)on the surface of these membranes are put in sunlight, they react with oxygen in the air to produce small amounts of hydrogen peroxide. Gang Sun explains that the process creates less hydrogen peroxide than what you would use to remove dirt on clothing, for example. But it is still enough to kill organisms.

    Rohan Tikekar is a food scientist with the University of Maryland. He described the development as “quite novel,” or new and different, Tikekar was not involved with the recent study. He said others have developed materials that produce disinfecting chemicals. But most only work under high-energy ultraviolet(U V)light, and not usual daylight. The new membrane also works in the dark for at least an hour or two because of chemical properties that can recharge its germ-killing powers. Tikekar called that an important improvement.

    Gang Sun said the new membranes, though still Far from perfect could be used for things other than protective equipment for health workers. They could also be added to packaging for fruits and vegetables to keep foods fresher and reduce the risk of being polluted. Some versions of the material use natural chemicals' Sun says that one of the next steps is to make it safe to sat

(1)、Which of the following statements is TRUE according to the passage?
A、Daylight helps to turn thin plastic barriers into germ-killing material. B、Gang Sun developed membranes alone because he was infected with Ebola, C、Hydrogen peroxide can kill live bacteria as it is a liquid. D、The membranes react with oxygen when pat in sunlight.
(2)、What is the attitude of Rohan Tikekar towards the new finding?
A、Cautious. B、Favorable. C、Doubtful. D、Critical.
(3)、What is the last paragraph mainly about?
A、The importance of the new membranes. B、The drawback of the new membranes. C、More probable uses of the new membranes. D、More influences of the new membranes.

    If you ever visit an English village, make sure to look out for morris dancing. Undoubtedly one of the strangest traditions of English culture, morris dancing is a form of folk dancing that dates back to the 15th century. If you ever get the opportunity, you really have to see it.

    Men and women wearing old-fashioned, shabby clothing dance in the streets of towns and villages across the country during the holiday periods. Women wear long, frilly (有褶皱边的) skirts and men wear short trousers with bells attached to them. They dance to traditional folk music which is often played on traditional musical instruments.

    Some groups carry heavy black sticks which they beat against each other while they dance. Other groups wave handkerchiefs in the air while they perform. The dances are usually performed near a pub so that when it's over, the dancers and audience can sing some traditional folk songs over a pint of beer. The celebrations will often continue long into the night, by which point most people are too drunk to think about performing again.

    Morris dancing is a great English tradition but it's facing a big crisis. As the years go by, fewer and fewer young people are joining morris dancing groups. The dancers are getting older and older and eventually. If you've ever had the fortune to see morris dancing, you may understand why teenagers aren't rushing to sign up. Putting it to the point, it's not exactly the coolest thing for an 18-year-old to be doing. Why dress up in bells and funny costumes when you could be going clubbing? Or playing sport? Or doing anything else?

However, it would be a great shame to lose such a fun and lively part of England's history and culture. It's important to look after some traditions and customs especially when it's something as harmless and happy as morris dancing. So here's a toast to the next generation of would-be morris dancers! Let's hope they don't leave it too late.

    Everyone takes drugs. Sometimes a drug might be called a herb but the effect is the same. Drugs and herbs can make life better for they are used to improve health. From the simplest headache to a cure for cancer, people believe that certain drugs can help them. But there is danger if the drugs are not used in a proper way.

    American teenagers sometimes use certain drugs to feel good. They call this “getting high”. The problem is that once a young man or a young woman has the feeling of “getting high”, they want to do it often. If school is boring or too hard, students might get depressed and a drug or herb might help them feel better. If the student takes too much of a drug, the body may change in a wrong way such as a confused mind, poor sight, a headache, and an uncomfortable stomach.

    Schools now have D.A.R.E.program which means Drug Abuse Resistance Education. This program was started so that young students from age 10 to 18 might understand how a drug affects their bodies. The main point of the program is education. Once a student understands certain drugs can cause ill health,he will know he should not use them.

    Education is the key to good nutrition as well. If a student eats correctly, he or she will be full of energy which leads to good study habits and good grades. Poor nutrition may cause the need for more sleep and poor concentration. Proper food is similar to the proper use of drugs. Both allow a healthy body to grow while misuse of them prevents a person from developing normally.

    One of India's top engineering schools has restricted Internet access in its boarding houses, saying addiction to surfing, gaming and blogging was affecting students' performance, making them lonely and even suicidal.

    Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. "Now, a student doesn't even know who lives two doors away from him because he is so busy on the Internet," said Prakash Gopalan, dean of Student Affairs. "The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion."

    IIT-Mumbai, with about 5,000 students, is one of the seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional lifestyles are known to be common among IIT students, and at least nine have committed suicide in the past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming.

    "Starting Monday, Internet access will be banned between 11 p.m. and 12:30 p.m. at IIT-Mumbai's 13 boarding buildings to encourage students to sleep early and to try and force them out of their shells." Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. "Now they will say we need to listen to a lullaby (摇篮曲) to go to sleep." said Rajiv, an electronics student.

Choose the one that fits best according to the information given in the passage you have just read.

    Why do so many Americans distrust what they read in their newspapers? The American Society of Newspaper Editors is trying to answer this painful question. The organization is deep into a long self-analysis known as the journalism credibility project.

    Sad to say, this project has turned out to be mostly low-level findings about factual errors and spelling and grammar mistakes, combined with lots of head-scratching puzzlement about what in the world those readers really want.

    But the sources of distrust go way deeper. Most journalists learn to see the world through a set of standard patterns into which they report each day's events. In other words, there is a traditional story line in the newsroom culture that provides a backbone and a ready-made narrative structure for otherwise confusing news.

    There exists a social and cultural disconnect between journalists and their readers, which helps explain why the "standard patterns" of the newsroom seem foreign to many readers. In a recent survey, questionnaires were sent to reporters in five middle-size cities around the country, plus one large metropolitan area. Then residents in these communities were phoned at random and asked the same questions.

    Replies show that compared with other Americans, journalists are more likely to live in upscale neighborhoods, have maids, own Mercedeses, and trade stocks, and they're less likely to go to church, do volunteer work, or put down roots in a community.

    Reporters tend to be part of a broadly defined social and cultural elite (精英), so their work tends to reflect the traditional values of this elite. The alarming distrust of the news media isn't rooted in inaccuracy or poor reportorial skills but in the daily conflict of world views between reporters and their readers.

    This is an explosive situation for any industry, particularly a declining one. Here is a troubled business that keeps hiring employees whose attitudes vastly annoy the customers. Then it sponsors lots of symposiums (讨论会) and a credibility project devoted to wondering why customers are annoyed and fleeing in large numbers. But it never seems to get around to noticing the cultural and class prejudices that so many former buyers are complaining about. If it did, it would open up its diversity program, now focused narrowly on race and gender, and look for reporters who differ broadly by outlook, values, education, and class.

阅读短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

    Florence, Italy

    Who should go: art lovers, Renaissance historians and leather handbag shoppers with high credit limits.

    When to go: spring or fall. Travelers usually avoid summer in Florence.

    Paris, France

    Who should go: starving artists, Henry Miller fans, traditional food lovers.

    When to go: spring is the best time. That's what they all say, anyway. Autumn isn't bad, either, but I'd rather be rooting around the south of France in search of truffles (松露) in autumn. Summer in Paris isn't bad, really.

    Amsterdam, Holland

    Who should go: lovers of Dutch Master (artists I mean, like Rembrandt, not cigars), bicyclists—it's a bike city in a flat land.

    When to go: it can rain at any time in Amsterdam, but that's not a reason for not visiting this fascinating city. Off season tourists will be rewarded with good enough weather to stick around. Summer is good for sun lovers.

    Madrid, Spain

    Who should go: night owls—Madrid never sleeps, art lovers—the Prado is second only to the Louvre in presenting serious art, party-goers.

    When to go: spring, when days are warm and the nights are pleasantly cool. Demand for outside eating and drinking starts becoming stronger in March or April. Street life peaks in June and then slows in July and August as the temperature peaks. Autumn is also good, although you'll risk some rains.

    Venice, Italy

    Who should go: romantic dreamers who like walking through automobile-free streets, your mother (she'll want you to take her there, trust me), almost anyone who wants to see something really different and romantic.

    When to go: February is the time when the famous Venice Carnival is held and the weather is usually cold and foggy—perfect weather for Venice. Summer? A large number of tourists in shorts and whiny children ruin the atmosphere. You'll greatly enjoy yourself there in spring and early fall.

    At the age of 14, James Harrison had a major chest operation and he required 13 units (3.4 gallons) of blood afterwards. The blood donations saved his life, and he decided that once he turned 18, he would begin donating blood as regularly as he could.

    More than 60 years and almost 1,200 donations later, Harrison, whose blood contains an antibody (抗体) that has saved the lives of 2.4 million babies from miscarriages (流产), retired as a blood donor on May 11. Harrison's blood is valuable because he naturally produces Rh-negative blood, which contains Rh-positive antibodies. His blood has been used to create anti-D in Australia since 1967.

    "Every bottle of Anti-D ever made in Australia has James in it," Robyn Barlow, the Rh program director told the Sydney Morning Herald. "It's an amazing thing. He has saved millions of babies. I cry just thinking about it." Since then, Harrison has donated between 500 and 800 milliliters of blood almost every week. He's made 1,162 donations from his right arm and 10 from his left.

    "I'd keep going if they let me," Harrison told the Herald. His doctors said it was time to stop the donations — and they certainly don't take them lightly. They had already extended the age limit for blood donations for him, and they're cutting him off now to protect his health. He made his final donation surrounded by some of the mothers and babies who his blood helped save.

    Harrison's retirement is a blow to the Rh treatment program in Australia. Only 160 donors support the program, and finding new donors has proven to be difficult. But Harrison's retirement from giving blood doesn't mean he's completely out of the game. Scientists are collecting and cataloging his DNA to create a library of antibodies and white blood cells that could be the future of the anti-D program in Australia.
