    One day, gardeners might not just hear the buzz of bees among their flowers, but the whirr of robots, too. Scientists have managed to turn an unassuming drone into a remote-controlled pollinator by attaching horsehairs coated with a special, sticky glue to the under part of it.

    Animal pollinators are needed for the reproduction of 90% of flowering plants and one third of human food crops. Chief among those are bees-but many bee populations in the United States have been in steep decline in recent decades. Thus, the decline of bees isn't just worrisome because it could spoil ecosystems. but also, because it could spoil agriculture and economy. People have been trying to come up with replacement techniques, but none of them are especially effective yet.

    Scientists have thought about using drones, but they haven't figured out how to make free-flying robot insects that can rely on their own power source without being attached to a wire. “It's very tough work." said Senior author Elijio Miyako, a chemist at the National Institute of Advanced Industrial Science and Technology. His particular contribution to the field involves a kind of glue, one he'd considered a mistake 10 years before and stuck in a storage cabinet. When it was rediscovered a decade later, it hadn't dried up or broke down at all. “I was so surprised because it still had high viscosity,” Miyako said.

    The chemist noticed that when dropped, the glue absorbed an impressive amount of dust from the floor. Miyako realized this material could be very useful for picking up pollen. He and his colleagues chose a drone and attached horsehairs to its smooth surface to imitate a bee's furry body. They coated those horsehairs in the glue, and then controlled the drones over flowers, where they would pick up the pollen from one flower and then deposit the pollen at another one, thus fertilizing it.

    The scientists looked at the hairs under a scanning electron microscope and counted up the pollen grains attached to the surface and found that the drones whose horsehairs had been coated with the glue had about 10 times more pollen than those that had not been coated with the glue.

    Mivako does not think such drones would replace bees altogether, but could simply help bees with their pollinating duties. There's a lot of work to be done before that's a reality, however. Small drones will need to become more controllable and energy efficient, as well as smarter, with better GPS and artificial intelligence.

(1)、What does the underlined word “viscosity” in Para.3 probably mean?
A、Hardness. B、Stickiness. C、Flexibility. D、Purity.
(2)、We can learn from the passage that           .
A、bees disturb both agriculture and economy B、scientists invented automatic robot insects C、Miyako found the special feature of the glue accidently D、bees in the United States are on the edge of extinction
(3)、A drone works best in picking up pollen when ___
A、it is coated with the glue B、its body is made like a bee's C、researchers control it precisely D、horsehairs with the glue are attached to it
(4)、According to Eijiro Miyako, the drones____
A、are not yet ready for practical use B、may eventually replace bees in the future C、are much more efficient than bee pollinators D、can provide a solution to economic depression

    They wear the latest fashions with the most up-to-date accessories(配饰). Yet these are not girls in their teens or twenties but women in their sixties and seventies.A generation which would once only wear old-fashioned clothes is now favouring the same high street looks worn by those half their age.

    Professor Julia Twigg, a social policy expert, said, “Women over 75 are now shopping for clothes more frequently than they did when they were young in the 1960s.In the 1960s buying a coat for a woman was a serious matter.It was an expensive item that they would purchase only every three or four years — now you can pick one up at the supermarket whenever you wish to.Fashion is a lot cheaper and people get tired of things more quickly.”

    Professor Twigg analysed family expenditure(支出) data and found that while the percentage of spending on clothes and shoes by women had stayed around the same — at 5 or 6 percent of spending — the amount of clothes bought had risen sharply.

    The professor said, “Clothes are now 70 percent cheaper than they were in the 1960s because of the huge expansion of production in the Far East.In the 1960s Leeds was the heart of the British fashion industry and that was where most of the clothes came from, but now almost all of our clothes are sourced elsewhere.Everyone is buying more clothes but in general we are not spending more money on them.”

    Fashion designer Angela Barnard, who runs her own fashion business in London, said older women were much more affected by the celebrity(名流) style than in previous years.

    She said, “When people see stars such as Judi Dench and Helen Mirren looking attractive and fashionable in their sixties, they want to follow them.Older women are much more aware of celebrities. There's also the boom in TV programmes showing people how they can change their look, and many of my older customers do yoga to stay in shape well in their fifties.When I started my business a few years ago, my older customers tended to be very rich, but now they are what I would call ordinary women.My own mother is 61 and she wears the latest fashions in a way she would never have done ten years ago.”

    When you hear the word “recycling”, what comes to your mind? The color green or global warming?

    What if I were to tell you there is a dark side of recycling? A type of recycling that does more than good. The dark side of recycling has nothing to do with the environment but rather has a lot to do with the recycling of ideas.

Environmental unrest is not the only trouble we must face. Idea pollution is quickly becoming widespread across the online world.

    Think about it. When was the last time you read an original blog post? I'm guessing it has been quite a while. Why do you think top bloggers of today win so much respect? Do you think they recycle their ideas? With each recycled idea the online world becomes much more polluted. Used content contributes to the ever increasing mass of digital smog.

    The first step to reduce pollution is simple: stop recycling. When you stop recycling, you will then be forced to take up the task of creating from your own ideas. When you recycle an excellent idea, it soon becomes good. When you recycle a good idea, it soon becomes just OK. The chain continues until the key part of what used to make the idea good is saturated, leaving you nothing but a pile of mess.

    In order not to pollute, your ideas must go beyond “just recycled”. Your ideas must stand out from the pollution of the web. For your voice and talent to be heard and seen, you must go far beyond the standard copy of your neighbours' ideas.

    For the next week, make a promise not to recycle. Let your ideas flourish and flow. Believe in your ability to create, because the death of recycling starts with YOU.

    One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem — inability to read.

    In the library, I found my way into the “Children's Room.” I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.

    There on the book's cover was a beagle which looked identical(相同的)to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.

Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.

    My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.

    I never told my mother about my “miraculous” (奇迹般地) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.

    Anyone who is afraid of failure and afraid to face challenges will never taste success, so said our professor in marketing. I laughed it off at that time, but got frightened when it actually happened in my life.

    I landed in a small city in the Middle East to set up a firm, a world-class car rental firm. Having decided on the project, I earnestly settled in preparation. With a positive mind, I told myself nothing should stop me now, and was more than keen to make it a success.

    However, the least expected thing happened. Iraq invaded Kuwait. Tension ran high in the region. Eventually the war broke out, and many people fled the country, leaving my firm in deep trouble.

    As usual, "things become difficult, and every effort seems to bring disappointment, it can be tempting to lower your expectations or even water down your goals and ambitions." I was no exception. I thought of running away. I remembered the words of Thomas Edison, "Many of life's failures are people who did not realize how close they were to succeed when they gave up."

    I decided to hang on, telling myself, "I am not afraid of challenges and obstacles." I stayed on through months of uncertainty and insecurity. Finances ran low, and banks could not wait to get their dues. To add to all this, the banks even threatened to take all my vehicles. I felt I made a wrong decision to move there. I was now ready to face failure.

    I was living against all hopes, believing that something good would happen. After 2 months the war ended. My persistence paid off: people started flooding back and the car bookings picked up, five times over.

    Success comes to the one who dares, even after failure, to think positively and look forward confidently. After all, it is only the experience that makes a man tough. Failure does not mean you will never make it. It means that it will take a little longer. It provides us with a learning experience.

Accines (疫苗) may soon make their first film appearance. Led by expert Maria A. Croyle, researchers have developed a thin sheet that preserves vaccines for long periods without refrigeration. This means the carefully cooled small bottles now used to ship vaccines could potentially be replaced by lightweight films that can be mailed in an envelope and stored on a shelf.

Croyle's laboratory began developing the technology in 2007. Inspired by amber's ability to preserve the DNA of insects, the researchers set out to create their own version of the substance by mixing "a lot of sugar and a little bit of salt, much like hard candy," Croyle explains. The vaccine-containing film is administered by mouth—sweet news for many who dislike needles.

The film is tailored to suit each specific vaccine candidate and provide a protective coating. "We've learned over time that the key to really stabilizing whatever the film holds is to have it intermixed with all the components," Croyle says, adding that the process is quick and uses affordable, standard equipment. "We really wanted to come up with something that would be transferable to developing countries."

Immunization(免疫) programs depend heavily on keeping vaccines cold(2℃-8℃) as they are transported, sometimes over thousands of kilometers to far-away locations. Delivery can be difficult and costly, and transport disruptions can cause the vaccines to be ineffective.

But this new product can store live viruses, bacteria and antibodies for several months at 20℃. In a paper published in Science Advances, the scientists show that the live viruses in one vaccine were preserved in the film even after 36 months. They also find that a flu vaccine suspended in their film compares favourably with a traditional flu shot(流感预防针). "The study demonstrates early proof of concept for an exciting platform for vaccine product development," says Lisa Rohan, a pharmacologist, who was not involved in the study. She also notes that each vaccine type would need a custom formulation(配方) for future stages of development.

Finding partners to mass-produce for clinical trials is the researchers' most pressing problem, Croyle says. They are also exploring packaging methods to keep their films stable up to 40℃.

Size is a major advantage—a letter-sized sheet of the film can carry more than 500 doses(剂) of vaccine, about 1⁄900 the weight of the same amount of traditional doses. By making it easier and cheaper to ship and preserve vaccines efficiently, Croyle says, the technology could vastly improve immunization rates the world over, particularly in middle- to low- income countries.
