How do you get a good night's sleep?

    You may put your pillow (枕头) at the proper height, drink a glass of hot milk or maybe listen to some light music before bedtime. {#blank#}1{#/blank#}When World Sleeping Day falls on March 21, it will be a good time to explore a long-ignored fact that may make you feel tired after you wake up. Scientists have discovered that the position of your spine (脊椎) is very important when you sleep.

    {#blank#}2{#/blank#}Let's have a look at the advantages and disadvantages of each position.

On your back

    Sleeping on your back is the ideal (理想的) position to be in. First of all, your spine is in the best position.{#blank#}3{#/blank#}The downside is the greater likelihood of snoring (打鼾) and sleep apnea (窒息).

Lying on belly

    {#blank#}4{#/blank#}Dr Vaclav Vojta, a US child development specialist, said this is bad for your back because it takes away the natural curve (曲线) of your lumbar (腰部的) spine. But he also noted that this helps to prevent some snoring and sleep apnea.

On your side

    Sleeping on our sides happened naturally while we were in the womb (子宫).{#blank#}5{#/blank#}Plus, sleeping on your side (the left side in particular) has been reported to reduce troublesome digestive problems like heartburn. The downside is the “dead arm” and finger numbness (麻木) from this position.

A. Lying face down with your legs straight and your arms right by your sides is a bad idea.

B. Sleeping on your side can be a quick fix for snoring and can help to improve breathing.

C. Do you and your friends ever talk about your sleeping position with each other?

D. And a new study suggests that the sleeping position has something to do with it.

E. Of the three sleeping positions, which one do you usually go for?

F. You are also less likely to have digestive (消化的) problems.

G. But one thing you may tend to ignore is sleeping positions.

    Valentine's Day, a day traditionally reserved for expressing romantic love, is observed practically all around the world. However, not many people are familiar with Sweetest Day. Actually it is a holiday, especially designed to express love and care for those who were routinely neglected（忽视）by society.

Sweetest Day was the idea of Herbert Birch Kingston, who worked for a company in Cleveland, Ohio. He felt that there were plenty of children, especially orphans and poor kids, who didn't necessarily get the attention they deserved. Thus in 1922, he launched the first Sweetest Day to give out boxes of candy to mainly poor children.

    Since the day picked was the third Saturday in October, this became the traditional time to celebrate Sweetest Day. The tradition was so enjoyed that people often looked beyond kindness to treating their own friends or family to treats on Sweetest Day.

    In the US, Sweetest Day is celebrated primarily in the Northeastern region of the US, still on the third Saturday of October. Yet news of the tradition, which began nearly 100 years ago, has spread to other parts of the country, especially as people who lived in those areas moved elsewhere. People may distribute candy or small gifts to those in patient homes, hospitals, foster homes, or mental institutions, and they may also treat friends and family to little gifts from the heart.

    In keeping with the original tradition, celebrating Sweetest Day should really be most focused on people who ordinarily don't have the good fortune of attention from friends or family, either due to difficult family circumstances or to poverty. This can be a great tradition to start if your community doesn't routinely celebrate the day, and there are many candy manufacturers that are willing to help donate or reduce costs on gifts intended for people in unfortunate circumstances.

    Far from the land of Antarctica (南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.

    For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.

    Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish's blood and measured its freezing point.

The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to

-2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.

    The scientists' next research job was clear: Find out what in the fish's blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.

    Study showed that it is an unusual kind of protein. It has many small sugar molecules（分子）held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.

    For a long time being happy was considered something that just happened, and there was nothing special about it. Now we know that getting along with other people is something that we can work at. It is possible to act in such a way that other people will like us better. One way is being unselfish, not wanting everything from our friends. Another way is to look for good points, not bad ones in other people. It is surprising how successful this treasure hunt can be.

    You don't have to be spineless (软弱的) in order to be popular. In fact, you will be liked and respected if you are not afraid to stand up for your rights. But do it politely and pleasantly. Being friendly and polite to your group, to other people and to strangers and especially to those who do not look important or do not interest you is one way to develop a good character.

    You can not expect to be perfect, and so you must learn not to be unhappy when you make mistakes. Everyone makes mistakes, and no one is to be blamed (责备) unless he refuses to learn from them. Many young people become discouraged when they know in themselves qualities (品格) that they do not like—selfishness, laziness, and other unpleasant qualities. Just remember that we all have some of these faults and have to fight against them.

    At the same time, it is important to remember that, while you are probably no worse than others, the best way to be happy is to think yourself above other people. When something is wrong, it is good sense to try to make it right. Perhaps you don't like a teacher or a classmate. Try to see why, and look at yourself, too. To be sure that you are not doing anything to make that person dislike you. Some day, things may turn out all right, then you will have to learn to get along the best with situation, without thinking too much about it. Worrying never helps in a situation you can't change.

    Confident, smart and high-tech, they're followers of pop culture and know what social networking is all about. They're tweens, children between the ages of 10 and 12. These young people are no longer little kids but they are not yet teenagers, because tweens are in a state of transition (转变).

    The tween years are hard for children. From a social point of view, tweens are dealing with quite a lot. They have to face changing relationships, middle school and a whole lot of pressure (压力) to succeed and fit in. They may become angry over seemingly small things. A bad test grade, an argument with a friend, a bad day on the ball field, or a request to clean a bedroom might set them off.

    Elizabeth Hartley-Brewer, a parenting expert in London and author of Talking to Tweens, says, "The tween years are when young people begin to realize the wider world and to see themselves as separate from their families."

    Right now, tweens' friends are everything to them. It's universal for the age, but they show it in different ways. For boys, the whole friendship thing is through technology and sports. Girls like to talk.

    Tweens are also a hot market. What do tweens consider cool? Music is at the top of the cool list, followed by going to the movies. "Being smart" comes third, tied with video games, followed by electronics, sports, fashion and protecting the environment, according to a report.

    Undoubtedly, tweens have great spending power in the United States. It was the tween market that made Justin Bieber and Harry Potter household names. Retailers(零售商) know tweens are a hot market for clothes, music and entertainment. Tweens have their own sense of fashion and enjoy their own parts of popular culture.
