    Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones, substances found in cocoa, tea and some kinds of vegetables, may improve age-related memory failure.

    Dr. Scott Small is a professor of neurology (神经病学) at Columbia University in new York City. He is the lead writer of a research paper describing the effects of cocoa flavones on brain activity. His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink made from cocoa beans or a low-level flavones drink. For a period of three months, some subjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study. Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memory tests.

    The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the lead researcher of a four-year study involving 18,000 adults. This study will use flavones capsules(胶囊). The study subjects will be divided into two groups and will take two pills per day. The capsules used will all look the same. But one group's capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo

    Dr. Manson says it's not necessary for people to start eating more chocolate, because a person would have to eat a huge amount of chocolate to get the same level of flavones given to the rest subjects. He adds many manufacturers have planned to remove the flavones from their chocolate products. Similarly, Dr. Manson says a cocoa-based flavones extract(提取)may be developed in the future But he says that more studies are needed to see how much flavones is good for our health.

(1)、What was done to the subjects after Dr. Small's study?

A、They were asked to take a high-level flavones drink. B、They were given capsules containing flavones. C、They were given brain imaging and memory tests. D、They were asked to take two pills of flavones capsules per day.
(2)、What's the similarity of the two experiments?

A、Both use high-level flavones capsules. B、The number of the subjects is the same. C、Drinks and placebos are used in both experiments. D、The subjects are divided into two groups in both experiments.
(3)、Why will Dr. Manson carry out the four-year study?

A、To prove the first experiment is wrong. B、To carry out the experiment further. C、To test how much flavones can improve our memory. D、To show eating chocolate is better to improve memory.
(4)、What can we learn from the last paragraph?

A、It's not necessary for us to eat chocolate. B、The more we eat flavones, the better our health will be. C、In the future we can get flavones without eating chocolate. D、It's easy for people to get the same level of flavones given to the test subjects.

    Recently, the TV show “Where are we going, Dad?” produced by Hunan SatelliteTelevision is a big hit across nation. Many famous stars brought their children to a strange village alone, and they had to spend 72 hours with their children there. The program fully showed us a modern version of the “how to be a good father”. As the young parents today are too busy to take care of their children, this new form of “Lost on the way” played by nanny Daddy and cute kids triggered(触发)a lot of people's emotional resonance(共鸣). Both the kids and their parents will find that their hearts are being drawn closer. But this kind of feeling has just proved that there is a big spiritual barrier between the modern parents and children.The TV shows like “Children are hard to support!”, “Where are we going, Dad?”, “hot mom” and “cute kids” are becoming more and more popular. All of these show the new parents' confusion in children's education and the appeal for the balance between career and family.

    In the real life, on the one hand, the young parents feel helpless because they are too busy to accompany their children under the pressures of work and life; on the other hand, they continue to do so. The data collected by HNTV shows that nearly two-thirds of their audience are female, among whom 36% are aged from 25 to 34.We can imagine such a scene that one evening a young mother is watching the show with her young children, while her husband is still at work or trapped in socializing, or maybe is just playing computer games in the bedroom. The story of a child without the company of father is still going on. In fact, it is sometimes the same to mothers. In a modern family, it is often the old who take the responsibility of raising a child. The participation of mother in the children's education is also very low.

    It is just this kind of confusion where the parents have gone in the modern family education, and where the parents will guide their children to go that “Where are we going, Dad?” shows us. If a child wants to grow up healthily and safely into a modern citizen with independent personality and free spirit, it is very important for him or her to follow the parents who serve as their first teacher. Maybe this is the real reason why such kind of TV programs could get hot. The truth is that children will go where their parents go; and society will go where the children go.

    Below is a selection from a popular science book.

    If blood is red, why are veins(静脉) blue?

    Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it's outside the body, when it's sitting in the vein near the surface of the skin, it's more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.

    Which works harder, you heart or your brain?

    That kind of depends on whether you're busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But in the long run, your brain probably tips it, because even when you're sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.

    Why do teeth fall out, and why don't they grow back in grown-ups?

    Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall our when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you're done. When they're gone, they are gone. This is because nature figures you're set for life, and what controls regrowth of your teeth switches off.

    Do old people shrink as they age?

Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effect of gravity(重力). Many (but not all) men and women do lose height as they get older. Men lose and average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don't really shrink! It is not that they are growing backwards —- their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little. Or, more often, become more bent and curved.

    Why does spinning make you dizzy(眩晕的)?

    Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you're spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you'removing while you're not.

    Where do feelings and emotions come from?

Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area —- from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet.

    If exercise wears you out, how can it be good for you?

    Because our bodies adapt to everything we do to them. And as far as your body is concerned, it's “use it, or lose it”! It's not that exercise makes you healthy, it's more that a lack of exercise leaves your body weak and easily affected by disease

    When I was eight, I got my first pair of glasses. Far from being made fun of at school, the only struggle I got was endless requests to try on my new glasses. Hearing about what happened at school, my father once looked at me and asked whether I had pretended to be the blindness just to look like Harry Potter?

    With my strange hair and glasses, I did nothing to avoid it, either. The Harry Potter books were the great pop cultural event of my generation, who began reading again. My school librarian, both confused and annoyed by us Potter fans, dealt with fights over the schools few old copies by setting a new rule: Harry Potter could be borrowed for only three days, instead of the whole week of borrowing period every other title was allowed.

    In the 20 years since the first book arrived on shelves, publishers and parents have been asking what has made J.K. Rowling's books so loved. It is better to look at the influence they have had on their readers. Yes, the books were about a boy taking on a dark and powerful enemy in the magical world, but they were also about love defeating hate, determination and choosing" between what is easy and what is right". Rowling's entire magical characters were all people we want to be.

    I grew up with Harry and together we became children with our own opinions, teens easy to get angry and young adults thinking of everything as normal. When the final book came out in 2007.I read it for 12 hours without a break and cried as I finished it. I felt something sad: the end of Harry's story signaled the end of my childhood. I was suddenly aimless. Meanwhile, my now Potter-mad father walked impatiently nearby, waiting for the proper moment to take the book away from his daughter.

    Harry Potter did shape my generation. As a girl who grew up mostly in peacetime, many of the ideas I found in these books were ones we had never come across before. The magical world's terrible treatment of non-human beings was the first description of slavery I knew. The treatment of Harry's teacher Remus Lupin, who hides his condition at work, is a metaphor(比喻) for the shame surrounding those who suffer from AIDS. And all settings like this may have real-world reflections .A study found that teenage Harry Potter readers showed more tolerance (包容) towards those who were suffering. Is it possible that Jeremy Corbyn's popularity among the young had anything to do with their literary education? Is it possible that Harry Potter, in the 20 years he has been with us, has inspired a generation to be more empathetic (感同身受), welcoming and socially open-minded than those before it? We will see, if not, at least my glasses are still cool.

    The flowers are blooming and the birds are singing as Melinda sits in the rose garden of the nursing home. She is recalling old times as she waits for her family's arrival. The nursing home has been Melinda's new settlement ever since Thomas passed away a week ago. Thomas had fought a long and hard battle against lung cancer for three years. Unfortunately, he has broken the promise that he and Melinda had made: to be with each other for every birthday. Melinda knew this was unrealistic (不现实的) but agreed to the promise for Thomas's sake.

    "Thomas, you are completely a dreamer." Melinda shouted to Thomas as he dragged on about living on an island with his beautiful wife. That's what she loved about him most—he had a vivid imagination. They got married at age eighteen and began having children right away. Mary came within the year, followed by Thomas Benjamin II, Lilly-Ann, and Joseph “Little Joey” George. The family lived an exultant life filled with laughter and love.

    "Mom!" Lilly shouted, but it really sounded like a howl. Melinda had lost herself in thinking about the life she had shared with her late husband. Lilly pushed her down the long dark halls of the nursing home until they arrived at the recreational room.

When the doors opened, Melinda put her hand over her mouth and was completely speechless. The room was crowded with the people nearest and dearest to her and the warmth and love was felt instantly. The night went on; stories and cocktails were shared and everything was perfect.

    However, when Melinda caught a moment to herself she looked around at her family. With a smile on her face, she raised her Manhattan and called out for a toast. “This one is for you, Thomas, though you are not here.”
