Happiness is for everyone. You don't need to care about those people who have beautiful houses with large gardens and swimming pools or{#blank#}1{#/blank#} and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.

    In fact, happiness is always around you if you put your heart into it. {#blank#}2{#/blank#} When you study hard at your lessons, your parents are always taking good care of your life and your health. When you get success, your friends will say congratulations to you. When you do something wrong, people around you will help you to correct it. {#blank#}3{#/blank#} All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.

    Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can't be bought with money. {#blank#}4{#/blank#}, because you have more chances to challenge yourself. So you cannot always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转的)door. When it closes, it also opens. {#blank#}5{#/blank#}

    Our brains work in complex and strange ways.There are some people who can calculate the day of the week for any given date in 40,000 years,but who cannot add two plus two.Others can perform complex classical piano pieces after hearing them once,but they cannot read or write.

    Dr.J.Langdon Down first described this condition in 1887.He called these people idiot savants.An idiot savant is a person who has significant mental impairment（损伤）,such as in autism（孤独症，自闭症）or retardation.At the same time,the person also exhibits some extraordinary skills,which are unusual for most people.The skills of the savant may vary from being exceptionally gifted in music or in mathematics,or having a photographic memory.

    One of the first descriptions of a human who could calculate quickly was written in 1789 by Dr.Benjamin Rush, an American doctor.His patient,Thomas Fuller,was brought to Virginia as a slave in 1724.It took Thomas only 90 seconds to work out that a man who has lived 70 years,17 days,and 12 hours has lived 2,210,500,800 seconds. Despite this ability,he died in 1790 without ever learning to read or write.

    Another idiot savant slave became famous as a pianist in the 1860s.Blind Tom had a vocabulary of only 100 words,but he played 5,000 musical pieces beautifully.

    In the excellent movie Rain Man,made in 1988 and available on video cassette,Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise,with his ability to perform complex calculations very rapidly.

    Today we more clearly recognize that the idiot savant is special because of brain impairment.Yet not all brain impairment leads to savant skills.Some studies have shown that people who have purposeful interruption of the left side of the brain can develop idiot savant skills.However few people wish to participate in such experiments.There are many excellent reasons for not undergoing unnecessary experimentation on one's brain.The term idiot savant is outdated and inappropriate.Virtually all savants have a high degree of intelligence and are thus not idiots.

    A new study shows that rising levels of planet-warming gases may reduce important nutrients in food crops.

    Researchers studied the effects of one such gas—carbon dioxide—on rice. The researchers grew rice plants in a controlled environment. They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century. They found that the resulting rice crops had lower than normal levels of vitamins, minerals and protein. The researchers said the effects of planet-warming gases would be most severe for the poorest citizens in some of the least developed countries. These people generally eat the most rice and have the least complex diets, they noted.

    In the experiment, scientists grew 18 kinds of rice in fields in China and Japan. They pumped carbon dioxide gas over the plants in an effort to create the atmosphere of the future. Rice grown under high carbon dioxide conditions had, on average, 13 to 30 percent lower levels of four B vitamins and 10 percent less protein. The crops also had 8 percent less iron and 5 percent less zinc（锌）an rice grown under normal conditions. However, vitamin E levels increased by about 13 percent on average.

    The results are bad news, “especially for the nutrition of the poorer population in less-developed countries,” said the University of Tokyo's Kazuhiko Kobayashi, who helped to write the report. That includes about 600 million people in Indonesia, Cambodia, Myanmar, Bangladesh, Laos and other nations, mainly in Southeast Asia, the report said.

    One of the scientists is Sam Myers of Harvard University in the American state of Massachusetts. He said that findings like this are an example of the surprises climate change create. “My concern is there are many more surprises to come,” he said.

    Myers noted that pollution, loss of some species, destruction of forests, and other human activities are likely to produce unexpected problems. He said that you cannot completely change all the natural systems that living organisms have grown to depend on over millions of years without having effects come back to affect our own health.

    The new study suggests a way to lower the nutritional harm of climate change. One way, Kobayashi said, is grow different forms of rice that have shown to be more resistant to higher carbon dioxide levels.

    During an earthquake, you should know what to do. If the earthquake strikes while you're inside a house, you should lie on the floor under a strong table or other furniture. If there is no furniture, you can cover your head with your arms and keep still in the corner of the room. You should keep away from windows, glass walls, or anything that can fall.

    If you are in bed, hold firmly onto your bed and make use of a pillow to safeguard your head. You may use a doorway but only when it is close to you. It should also be considered whether it is strong enough to deal with the load.

    If you are running out, do not use lifts, even if they work. Electricity may go out at any time. Many injuries happen when people try to rush out. This means you ought to stay in your house or perhaps wherever you are.

    When you stay outdoors, you should stay far from buildings, power wires or lights. You should be in the open until the quake stops. Remember that many earthquake deaths outside the house come from falling-apart walls, flying glass and other falling things.

    If an earthquake strikes and you are driving, you should pull up to the side of the highway and stop as quickly as possible. You ought not to stop under trees, buildings or energy wires. Don't stop in the middle of the street as it could trouble others.

    When trapped, you shouldn't move. Your mouth should be covered with a piece of clothing or a handkerchief. This is because it is possible for you to breathe in some dust. Do not shout whenever possible. You should only shout in the end to get help from rescuers.

    Nine years ago, when the closest and largest full moon fell on March 19, 2011, many people used the term, "supermoon", which we had never heard before. In 2012, we heard this term again to describe the year's closest full moon on May 6, 2012. Supermoons also appeared in 2013, 2014, 2015, 2017 and 2019.

    What does "supermoon" mean exactly? And how special was the March 19, 2011 supermoon?

    The word "supermoon" didn't come from astronomy. Instead, it came from astrology (占星学). In 1979, astrologer Richard Nolle defined it as a new or full moon which occurs at or near its closest point to the earth in its orbit. In short, the earth, moon and sun are all in a line, with the moon at its nearest point to the earth.

And the full moon of March 19, 2011 was the largest moon of that year. This "supermoon" was at perigee (近地点) — its closest point to the earth in its orbit. It was bigger and brighter than other full moons of 2011. Astronomers call this sort of close full moon a perigee full moon.

    That doesn't sound very special, does it? In fact, the March 2011 full moon lined up much more closely with perigee than Nolle's original definition. But were you able to notice with your eyes alone that this full moon was bigger or brighter than usual? Astronomers said no. But it was fun to stand outside under this full moon and know that the moon was closer than ever.

    In 2019, there were three supermoons. The first supermoon of 2019 was the Super Blood Wolf Moon on January 21, which occurred with a total lunar eclipse (月全食) at the same time, also known as a "blood moon". The second supermoon of 2019 was on February 19, also called the Snow Moon, which was the closest full moon of the year. The third and final supermoon of 2019, known by Native Americans as the Worm Moon, occurred on March 21. It fell on the day of the vernal equinox (春分), which signals the end of winter and the beginning of spring.

We've all heard the advice to "get out of your comfort zone" by taking on a new challenge. A recent study goes a step further: Make discomfort a direct goal. That's more likely to motivate you {#blank#}1{#/blank#} if you only focus on what you hope to learn.

In the first of five experiments, the researchers assigned several hundred students training at Second City Chicago {#blank#}2{#/blank#}（participate） in a small-group improvisation（即兴） exercise, and then instructed half of the group that their goal during the session was "to feel awkward and uncomfortable." The rest, {#blank#}3{#/blank#}（that） in the control group, {#blank#}4{#/blank#}（tell） to "feel yourself developing new skills." Members of the first group kept at the exercise longer than the others did and took {#blank#}5{#/blank#}（great） risks.

Experiments {#blank#}6{#/blank#}（involve） other dimensions of personal growth—engaging in expressive writing, learning about gun violence, and hearing about opposing political {#blank#}7{#/blank#}（belief）—produced similar results.

Reframing anxiety as excitement has been proven a way to improve singing in front of strangers, and thinking of stress as {#blank#}8{#/blank#} means to boost achievement demonstrated a stress-management technique.

"When people reinterpret negative experiences as {#blank#}9{#/blank#}（function）, they are more willing to engage in tasks that call forth those experiences," the researchers explain. "Instead of seeing discomfort as unrelated to the goal {#blank#}10{#/blank#} a signal to stop, they will start perceiving it as a sign of progress toward their goal."
