One year, a college in the United States announced that it would offer a lot of money for the pure white marigold (金盏花). The high reward attracted so many people, but in the nature, besides golden, the marigold is brown, and it is not easy to get the white one. So after they were excited for a time, many people had forgotten the announcement.

One normal day after 20 years, the college received a letter and 100 seeds of pure white marigold. It was an old woman of over 70 years old. Some experts in the college doubted it, but in order not to let her down, those seeds finally took root (根) in the earth. The miracle appeared after one year; the field was covered by pure white marigold.

Therefore, the old woman who was always unknown to the public became a new focus.

The old woman was a flower-lover. When she read the announcement 20 years ago, she got very excited like others. But her eight children were totally against her decision. After all, a woman who never knew the seed genetics (遗传学) couldn't complete what the experts could never do, so her thought was only a day dream.

Still, the old woman didn't change her mind and went on working. She planted some of the most common seeds and took good care of them. A year later, when the marigold came out, she chose one faintest(最暗淡的) from those golden and brown flowers and got the best seed. The next year, she again grew them and chose. . . Day after day, year after year, through many seasons, the old woman's husband died, her children flew far, a lot of things happened in her life, but only the wish to grow the pure white marigold took root in her heart.

Finally, after 20 years on the day we all know, in the garden she saw a marigold, which was nearly white, but as white as silver or snow.

A problem even experts couldn't deal with was solved by an old woman who didn't understand genetics. Was it a miracle (奇迹)?

To take root in the heart, even the most common seed can grow into a miracle!

(1)、The passage mainly talks about       .

                                                                                         The University of Sheffield

    Back to its origin

    The University of Sheffield is a research university in the city of Sheffield in South Yorkshire, England. It is one of the original “red brick” universities, which are a group of top and famous old universities. The University of Sheffield was originally formed by the combination of three colleges. The Sheffield School of Medicine was founded in 1828, followed in 1879 by the opening of Firth College by Mark Firth, a steel manufacturer (制造商), to teach arts and science subjects. Firth College then helped to provide money for the opening of the Sheffield Technical School in 1884 to teach applied science. In 1897 the three institutions were joined together to form the University College of Sheffield, which in turn became the University of Sheffield by Royal Charter (特许) in 1905. This university is famous for its good education and boasts a number of Nobel Prize winners among its former students.

    More information

    System: The University has five departments: Arts and Humanities; Engineering; Pure Science; Social Sciences; Medicine, Dentistry and Health. Sheffield also has many research programs in fields including aerospace, environmental science, psychology, and biology.

    City show: Sheffield is a lively city in the north of England. Sheffield is known as the greenest city in Europe because of its 2 million trees. As a result, there are many parks and woods throughout the city and beyond. Sheffield is the greenest city in England with 150 woodlands and 50 public parks within the city. Once, in Sheffield, the folk hero—Robin Hood lived in Sherwood Forest with 150 of his loyal friends. And Charlotte Bronte, the English writer noted for her novel Jane Eyre was born in Sheffield.

    As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things.

    Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight, Very often the effects of pollution are not noticed for many months or years because the first organisms(生物体)to be affected are either plants or plankton. But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it's not until dead fish and water birds are seen at the river's edge or on the seashore that people realize what is happening.

    Where do the substances which pollute the water come from? There are two main sources of sewage(污水)and industrial waste . As more detergent(洗涤剂)is used in the home, so more of it is finally put into our rivers, lakes and seas . Detergents harm water birds, dissolving the natural substances which keep their feathers water - proof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead(铅).

    So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.

    Peter Skyllberg, a Swedish man, was trapped in his car for two months, with temperatures reaching -30oC, with no food or water, and yet he survived. The best explanation was that his vehicle created an “igloo (snow house) effect” and protected him from the extremely low temperatures and that his body would hibernate(冬眠) during this time.

    Can humans get into a low-energy consumption state like a bear by reserving energy, and reducing body temperature? Chinese scientists are looking for the key to regulating body temperature.

    Scientists have found the hypothalamus (下丘脑), an area in the central lower part of the brain, is responsible for regulating body temperature. Wang Hong, a brain scientist at the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences, led her team to mark the neurons (神经元) responsible for regulating body temperature in mice by means of a cutting-edge genetic biology technique. In the experiments, they injected (注射) drug into mice to make the body temperatures of the mice drop rom 37℃ to 27 in two hours. The team found the change in body temperature caused no harm to the health of the mice. “We don't know if we can develop a drug that can control human body temperature. We still need a lot of study.” Wang said.

    Chinese scientists are not alone in such research. Body-cooling techniques are being used in pioneering hospitals around the world. Dutch doctors are now using low temperatures for patients who have suffered brain injuries in accidents, According to doctors working in Florence, it may even help to save the brains of babies who are born suffering from severe epileptic fits (癫痫病发作).

Max Du won the Canada-Wide Science Fair. His project is a drone (无人机) to save people who go into cardiac (心脏的) arrest. Max got the inspiration during Christmas break last year. "I got a toy drone from my parents, but I couldn't fly it because it is snowy." Max said. "So I played with it at home, and it got me thinking how a drone could be used as an indoor robot that could help people."

About 35, 000 people have cardiac arrests in Canada each year. Most of those happen outside of a hospital, of whom fewer than 10 percent survive. Max believed a drone could offer faster support and life-saving medicine, but he had to build it himself to know for sure.

Testing his drone took about six months. Max's parents had to deal with their son's constantly flying and crashing in the home. Every time Max would create an exciting innovation, such as an extendable arm, it would add extra weight to his drone, causing it to break apart. Then Max would have to buy all new parts. Max tested using more lightweight materials until his design was more balanced.

Through trial and error, the 14-year-old boy finally got it right. His drone can open a door handle, fly in the air and then land softly on the ground. A new extendable arm can be released to administer a shot or hand a patient lifesaving medicine. A built-in camera could directly conference with an emergency response team whose members could monitor the patient remotely.

Max plans on applying for a patent (专利) so he can make connections in the health-care industry to get it made for real. He's spent his summer learning about artificial intelligence at California's Stanford University as one of 32 kids selected worldwide. He'll head next to the University of Pennsylvania to take a college-level robotics class before returning to high school in September.
