    Can exercise during childhood protect you against memory loss many decades later? Exercise early in life seems to have lifelong benefits for the brain, in rats at least.

    “This is an animal study, but it shows that physical activity at a young age is very important—not just for physical development, but for the whole lifelong track of cognitive (认知的) development during ageing,” says Martin Wojtowicz of the University of Toronto, Canada. “In humans, it may delay the appearance of Alzheimer's symptoms (阿兹海默氏症), possibly to the point of preventing them.”

    Wojtowicz's team divided 80 young male rats into two equal groups, and placed running wheels in the cages of one group for a period of six weeks. Around four months later-when the rats had reached middle age-the team taught all the rats to connect an electric shock with being in a specific box. When placed in the box, they froze with fear.

    Two weeks later, the team tested the rats in three situations: exactly the same box in the same room, the same box with the room arranged differently, and a completely different box in a different room.

    The rats without access to a running wheel when they were young now froze the same percentage of times in each of these situations, suggesting they couldn't remember which one was dangerous. But those that had been able to run in their youth froze 40 to 50 percent less in both changed box settings.

    “The results suggest the amount of physical activity when we're young, at least for rats, has influence on brain and cognitive health-in the form of better memories-when we're older,” says Arthur Kramer of Northeastern University in Boston, who has found that, in humans, exercise promotes the growth of new brain cells.

(1)、The study shows that       .
A、physical activity is important for physical health B、using the running wheels is of benefit to the rats' growth C、physical activity can prevent human's Alzheimer's symptoms D、the more exercise a rat has when young, the better memory it will possess when older
(2)、How are Paragraph 3 and 4 mainly developed?
A、By analyzing causes. B、By giving an example. C、By describing the process. D、By showing differences.
(3)、What does the underlined word “it” in Paragraph 2 refer to?
A、Exercise. B、Development. C、Benefit. D、Study.
(4)、What is the author's attitude towards the animal study?
A、Negative. B、Objective. C、Critical. D、Doubtful.

Tail Spin

    Two dolphins race around in a big pool in the Ocean Park. The smaller dolphin Grace, shown off a few of her tricks, turning around and waving hello to the crowd. The most amazing thing about her, however, is that she's even swimming at all. She doesn't have a tail.

Grace lost her tail as a baby when she got caught up in a fish trap. When the dolphin arrived at the Ocean Park in December 2005, she was fighting for her life. “Is she going to make it?” Her trainer, Abbey Stone, feared the worst. Grace did make it — but her tail didn't. She ended up losing her flukes and the lower part of her peduncle.

Over the past six years, she has learned to swim without her tail. Dolphins swim by moving their flukes and peduncle up and down. Grace taught herself to move another way—like a fish! She pushed herself forward through the water by moving her peduncles from side to side.

    The movement put harmful pressure on Grace's backbone. So a company offered to create a man-made tail for her. The tail had to be strong enough to stay on Grace as she swam but soft enough that it wouldn't hurt her.

    The first time Grace wore the artificial tail. She soon shook it off and let it sink in the bottom of the pool. Now, she is still learning to use the tail. Some days she wears it for an hour at a time, others not at all. “The tail isn't

necessary for her to feel comfortable,” says Stone, “but it helps to keep that range of motion(动作) and build muscles(肌肉).”

    Now, the dolphin is about to get an even happier ending. This month, Grace will star in Dolphin Tale, a film that focus on her rescue and recovery. Her progress has inspired more than just a new movie. Many people travel from near and far to meet her. Seeing Grace swim with her man-made tail gives people so much courage.

    It's comforting to think if you were somehow swallowed by a whale, you'd simply hang out in his stomach until he eventually spat you out, unharmed and whole. Unfortunately, your chance of ending up in this type of situation is pretty low.

    In 2012 reporter Ben Shattuck read the records at the New Bedford Whaling Museum Research Library. Despite his extensive research at one of the most comprehensive whaling archives(档案), he failed to find a single report of anyone ever being swallowed alive by a whale. He found plenty of reports of whalers who were bitten or injured by the creatures, and several who died after fighting with a whale, but none related to swallowing.

    With whales' large mouths, it certainly seems possible that a whale could swallow someone whole, so why is it so unlikely? Baleen whales, or whales without teeth, are some of the largest creatures on the planet. Despite their massive size, baleen whales could never get you into their bellies thanks to their relatively small esophagus(食道). These whales are designed to eat small sea creatures, and the opening in their throat is only about as large as a basketball, so you'd never make it that far.

    But what about toothed whales? Sperm whales eat whole seals, so you could easily fit down their throats and into their stomachs. However, once you reached the first of the sperm whale's four stomachs, your journey would probably end quickly. Not only would the whale's stomach acid make quick work of you, but you'd experience a distinct lack of air on the inside. Actually, you're more likely to get eaten or injured as you try to make it past the sperm whale's sharp teeth. Plenty of whalers, have fought with sperm whales and lost their hands or lives due to these mean teeth.

    America's top education official says many schools are spending too much time teaching the "basics"—reading, math and writing. It might seem opposite to what educators have been promoting. But U.S. Education Secretary John King says children really deserve access to a well-rounded education that includes music and arts because it will help them go into being well-rounded, well-educated persons.

    King spoke about his own education when explaining why schools need to teach more than math, reading and writing.

    King grew up in New York. Both his parents died when he was quite young. In his house, things were often crazy and frightening. It was his teacher, Mr. Osterwei, who helped him escape his difficult life. Quite often, the teacher took him and his classmates to the theater, the zoo, the ballet and famous Museum of Natural History. "Those were powerful, life-changing experiences, "King says. King graduated from Harvard University. He received his law degree from Yale University. He took charge of New York State public schools from 2011-2015. The U.S. Senate approved him as Education secretary last month.

    Many schools spend almost all funding on the "basics" because they lack money for other subjects, King says. Or they want students to do better on tests used to compare student performance.

    Students need to connect their studies and things that matter to them personally, such as music if they are to become "sophisticated(水平高的) thinkers". A 2013 report by UNESCO says today's world needs people able to solve new and unusual problems. It says arts can help students find those answers. In the report, UNESCO said teaching the arts in China, South Korea and Japan is different.

    From that in many Western countries, the emphasis(重点) in those three countries is "on joyful experiences and children's interests." In the West, educators are more likely to connect the arts to reading, writing and math. A 2014 report tried to compare how well countries teach children how to solve problems. It found Singapore, South Korea, Japan, China, Canada, Australia and Finland with the highest scores for 15-year-olds. Singapore led the way with a score of 562 out of a possible 1, 000. The average score was 500. The United States had a score of 508.

    The Broadcom MASTERS competition aims to find a balance between celebrating individual accomplishments and acknowledging that science seldom happens alone. The competition takes off when students from around the country are teamed up and have to solve a series of hands—on challenges in the spotlight.

    Nowadays, kids are fed with “the myth of the lone scientist”, so placing such challenges in the middle school period has a huge potential for impact. The focus on teambuilding skills gets students excited before more fears and stereotypes(成见)set in.

    The initial pool of qualified students comes from the participants in nation-wide science fairs. Those who score in the top 10%(about 10, 000 kids)have the qualification to apply. The judges select the top 300 young scientists, and that group is finally narrowed to 30 finalists.

    Selection at this stage is clearly an honor in itself, but it counts as step one for the finalists. They are then flown to Washington, D. C. and placed into teams of five for the hands-on part of the competition. Each team is made up of students with different talents and skills, including academic focus and experience.

    Unlike the science fairs, where most of the work takes place behind the scenes and students share a polished outcome, the hands-on challenges create a space where the work is the competition itself. The students take up a range of challenges in science, technology, engineering, math and so on. Each of the challenges will need the insight and skills of multiple team members.

    Judges observing the challenges aren't just looking for outcomes but also for leadership, teamwork and problem solving.

    The Broadcom MASTERS attracts increasing numbers of passionate and talented young people who are eager to take part in a program that helps them grow as scientists, engineers and inventors. It lets the students experience a sense of coming together with true peers. More importantly, it provides them with new skills to tackle future challenges.
