We live in a sweet world. The average American kids eat more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today thati they did in the 1970s. We all know that too much sugar isn^t good for us. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to do a study on the bad effects of sugar. They found it could have serious effects on people's health.

Sugar is found not only in sweets and candies, but also in many house?hold items like pasta and crackers.

During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice produced 25% fewer offspring (后代)than the other mice.

Scientists often use mice for research because they have a similar genetic(基因的)structure to humans. "Since most substances (物质)that are danger?ous in mice are also dangerous in people, it's likely that those physical prob?lems that cause those mice to have increased deaths also work in people," says study author James Ruff of the University of Utah. Findings from this study show bad effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives.

Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation's sugar need will provide for a truly sweeter future.

This could be the perfect gift for the partner who embarrasses you on the dance floor. Smart socks, which can teach you to dance, may be the an?swer for anyone with two left feet.

The socks have been developed as a running tool to help runners im?prove their skills. Thanks to the socks, users can accurately (精确地)re-cord not only how far and fast they run but also how well. It means the user maximizes(最大化)his/her performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibres (纤维)that watch the movements of your feet. They look, feel and can be washed like normal clothes.

Sensors (传感器)record each movement and send it by an ankle trans?mitter (脚裸发射器)to a smart phone. Then a "virtual coach" application shows the information and can tell the users,what they are doing wrong, aijd help improve skills in any task with feet.

The socks should be useful to athletes and weekend joggers. "People think running is so easy and of course everybody can do it but not necessarily safely and well," Dr Da vide Vigano said. A recent study showed that be?tween 60 and 80 per cent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such as golf? or even to help to teach women to walk better in high heels.

Mr Vigano said, "People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely.,,

Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around $ 120, which will go on sale in March.

12.  What does the underlined part "anyone with two left feet" refer to?

  A.  People who are disabled.

B.  People who are interested in dancing.

C.  People who are not good at dancing.

D.  People who invented the socks.

13.  What's special about fibres that the socks are made of?

  A.  They feel much softer than normal clothes.

B.  They can monitor the movements of feet.

C.  They are expensive to produce.

D.  They act as a smart phone for users.

14.  Which of the following is NOT mentioned about the socks?

  A.  They can improve the skill of running.

B.  They can help women walk better in high heels.

C.  They can teach people to dance well.

D.  They can be worn for days without washing.

15.  According to Dr Vigano, _______ .

  A.  everyone can make good use of the smart socks

B.  users can run as fast as they like with the socks

C.  60 to 80 per cent of runners would like to buy the smart socks

D.  no runners will get hurt, thanks to the socks

  This may be music to your ears.

  Researchers P. Jason Rentfrow and Samuel Gosling gave3,500 people a personality quiz. Then they asked them to name their favorite kind of music. "We found that the musical style people like are closely linked to their personalities," Gosling says.

 In choosing a friend, one should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair weather friends. They will be with you as long as you have money or luck,but when you are down,they will run away. How do I know when I have found a good friend? I look for certain quali?ties(品盾)of character,especially understanding, honesty and reliability(可靠).

  Above all else,I look for understanding in a friend. A good friend tries to understand how another person is feeling. He is not quick to judge. Instead, he tries to learn from others. He puts himself in the other person's place, and he tries to think of ways to be helpful. He is also a good listener.

  At the same time,however, a good friend is honest. He does not look for faults(过错)in others. He notices their good points. In short,a friend will try to understand me and accept me.

Another quality of a friend is reliability. I can always depend on a good friend. If he tells me he will meet me somewhere at a certain time,I can be sure that he will be there. If I need a favor, he will do his best to help me. If I am in trouble, he will not run away from me.

  There is a fourth quality that makes a friend special. A special friend is someone with whom we can have fun. We should enjoy our lives, and we would enjoy our friendship. That is why I especially like friends who are fun to be with. A good friend likes the same things I like. We share experience and learn from each other. A good friend has a good sense of humor (幽默),too. He likes to laugh with me. That is how to share the joy of being friends. And I know that he is looking for the same quality in me.

  When I meet someone who is reliable, honest, and understanding, I know I've found a friend!

 English idioms(习语)are widely used,especially in the spoken language. Here are some examples for you. Do you know what they mean? By the skin of your teeth

  Ask for the moon

  If someone tells you not to ask for the moon,they mean you can't ask for something that you cannot get or have,or try for something impossible. On cloud nine
