{#blank#}1{#/blank#}

    We are drawn to people who smile. There is an attraction factor. We want to know a smiling person and figure out what is so good because anxieties can push people away, but a smile draws them in.

Smiling changes our mood

Smiling lowers your blood pressure.

    When you smile, there is a measurable reduction in your blood pressure. Give it a try if you have a blood pressure monitor (血压计) at home. Sit for a few minutes and take a reading. Then smile for a minute and read it again while still smiling. {#blank#}4{#/blank#}

Smiling lifts the face and makes you look younger.

The muscles we use to smile lift the face, making a person appear younger. Don't go for a face lift, just try smiling your way through the day — you'll look younger and feel better.

    There is an English saying: “{#blank#}1{#/blank#} Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body{#blank#}2{#/blank#}

    Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise{#blank#}3{#/blank#}If laughter exercises the body, it must be beneficial.

    Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated the pain for the longest time was the group which listened to a funny program.{#blank#}4{#/blank#}

    {#blank#}5{#/blank#}They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

A. Laughter can change one's life.

B. As a result of these discoveries, some doctors in the United States now hold laughter clinics in which they help to improve their patients' condition by encouraging them to laugh.

C. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.

D. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach and even the feet.

E. Although laughter helps cure the disease, doctors still can not put this theory into clinic practice.

F. Laughter is the best medicine.

G. They have found that laughter really can improve people's health.

    Larger brain size linked to longer life in deer. The size of a female animals' brain may determine whether they live longer and have more healthy later generations, according to new research led by the University of Cambridge.

    The study, published in the Royal Society Open Science journal, shows that female red deer with larger brains live longer and have more surviving later generations than those with smaller brains. Brain size is heritable and is passed down through the generations. This is the first extensive study of individual differences in brain size in wild mammals and draws on data comparing seven generations of deer.

    Across species of mammals, brain size varies widely. This is thought to be a consequence of specific differences in the benefits and costs of a larger brain. Mammals with larger brains may, for example, have greater abilities that enable them to adapt better to environmental changes or they may have longer lifespans. But there may also be disadvantages: for instance, larger brains require more energy, so individuals that possess them may show reduced ability to give birth to young babies.

    The researchers, based at the University of Cambridge's Zoology Department and Edinburgh University's Institute of Evolutionary Biology, wanted to test if they could find more direct genetic or non-genetic evidence of the costs and benefits of large brain size by comparing the longevity(长寿) and survival of individuals of the same species with different sized brains. Using the skulls of 1,314 wild red deer whose life histories and breeding success had been monitored in the course of a long-term study on the Isle of Rum, they found that females with larger endocranial volumes(脑腔容量) lived longer and produced more surviving offspring in the course of their lives.

    Lead author Dr Corina Logan, a Gates Cambridge Scholar, says, "The reasons for the association between brain size and longevity are not known, but other studies have suggested that larger brains are a consequence of the longer-lived species having longer developmental periods in which the brain can grow. These predictions were generated from cross-species correlations; however, testing such hypotheses requires investigations at the within-species level, which is what we did. "

    Dr Logan adds, "We found that some of the cross-species predictions about brain size held for female red deer, and that none of the predictions were supported in male red deer. This indicates that each sex likely experiences its own set of trade-offs(权衡,协调) with regard to brain size. "The study also showed that females' relative endocranial volume is smaller than that of males, despite evidence of selection for larger brains in females.

    Professor Tim Clutton Brock, who set up the Rum Red Deer study with Fiona Guinness in 1972 and started the work on brain size, points out, "The reason that this kind of study has not been conducted before is that it requires long term records of a large number of individuals across multiple generations and data of this kind are still rare in wild animals."

    The world we live in gets more mechanized every year. Some countries which were mainly agricultural a hundred years ago have now become industrial. New factories and towns have been built on good agricultural land. There are now fewer farms to serve a much greater population, so these farms must be more efficient in order to produce as much food as possible. There is no place in the modern agricultural world for the inefficient farmer. Unfortunately, many of the picturesque aspects of farming are disappearing in the search for efficiency. The more tractors are used, the fewer horses are needed. Everyone agrees that horses are far more pleasant to look at than tractors. But they are less efficient. Cows are usually milked by machinery nowadays, and even pigs are fed automatically. There is not much art or poetry on the modern farm, and the old traditional idea of a farm as a slow, peaceful, romantic place is totally wrong nowadays.

    The modern farmer has to be a mechanic, a scientist, an accountant and a gambler. The more mechanized farming becomes, the more expert the farmer has to be. He must understand what machinery is necessary for his kind of farm, and he must know how to use it efficiently. He must also understand the new technical advances in agriculture, and how to use chemical and synthetic products to improve his crops. The more workers a farmer employs, the more he must know about the problems of wages and taxes. As in any other industry, most modern farmers find it necessary to employ office staff to deal with these. But although he has more modern equipments and far more scientific aids than his grandfather had, the farmer is still dependent upon the weather. As he can never be sure what the weather will do, he must be prepared to take risks, and face the possibility of losing everything.

    The following are some of history's most inspirational women recommended by Therese Borchard.

    Who Was Mother Teresa? ￥66.00

    Born in Macedonia, Mother Teresa(1910—1997)taught at St. Mary's High School, in Calcutta, India, but was forced to do something about the suffering and poverty. In 1950 she founded the Missionaries of Charity. Although her devotion to the poor is inspiring, it's her persistence(坚持不懈)through years of doubt, as recorded in her private journals, that inspired me the most.

    The Diary of a Young Girl ￥55.10

    In The Diary of a Young Girl, Anne Frank (1929—1945) documented her life in hiding from 1942 to 1944 during the German Occupation of the Netherlands. She is a role model of honesty, strength, and hope for me — that even in the most miserable circumstances, you can lead with love.

    A Life of Discovery ￥111.10

    "Do one thing every day that scares you," wrote Eleanor Roosevelt (1884—1962). She had a lot to choose from, as her life was full of challenges. Eleanor inspires me to bravely deal with problems that matter to me, and to find her way through life's trials and hardships with gracefulness and determination.

    Story of My Life ￥32.50

    A deaf-blind author from Alabama, Helen Keller (1880—1968) provides a powerful example of a woman through two major disabilities to achieve a meaningful life. "We could never learn to be brave and patient if there were only joy in the world," she said. Her attitude of hope and optimism inspires me to use my suffering to become a better and wiser person, to go beyond my pain into service of others.
