People who are cheerful and relaxed are less likely to suffer from colds.It's   1   that being full of vim(活力) and vigor(精力)helps the body   2   illnesses, say the researchers from Carnegie Mellon University(CMU)in Pittsburgh.

"We need to take more seriously the possibility that a   3   emotional style is a fighter player in disease risk," says psychologist Sheldon Cohen, the study's lead researcher.

In a previous study, Cohen and his colleagues found that people who   4   to be cheerful and lively were   5   likely to develop sniffles, coughs, and other cold symptoms (症状).

Those findings were interesting, but they didn't prove that a person's   6   affects whether he or she gets sick. it was still possible that a person's underlying personality is   8   matters.

 9   suggests, for instance, that certain people are naturally more likely to be outgoing(外向的)and   10  , with high self-respect and a sense of  11   over life.This would mean that who we are, not how we feel, finally decides our   12   of catching colds.

To figure out which mattered more (personality or  13  ), the CMU team   14  193 healthy adults.The researchers talked to each person over the phone every evening for 2 weeks.They told the researchers about the positive and negative   15   they had experienced that day.

The results showed that everyone in the study was   16   likely to get infected.Their symptoms(征兆), however,   17   depending on the types of emotions that they had reported over the   18   2 weeks.

Scientists   19   about whether negative emotions or positive emotions have a stronger   20   on how healthy we are.For now, it can't hurt to look on the bright side more often than not!

Did you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s.Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent(聪明的)than women.Right? Wrong.Men and women always score similarly on intelligence tests, despite the difference in brain size.Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain.The brain consists of “grey matter” and “white matter”.While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes.

It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women.This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time.When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.

There are other important differences between two sexes.As white matter is the key to spatial(空间的) tasks, men know better where things are in relation to other things.“A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher.That may explain one of life’s great mysteries: why men refuse to ask for directions…and women often need to!

The differences begin when fetuses(胎儿) are about nine weeks old, which can be seen in the action of children as young as one.A boy would try to climb a barrier (障碍物)before him or push it down while a girl would attract help from others.These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills.It may all go back to our ancestors(祖先), among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.

If all this disappoints you, it shouldn’t.“The brain changes throughout our lives according to what we do with it.” says a biologist.

Runners in a relay(接力)race pass a stick in one direction.However, merchants passed silk, gold, fruit, and glass along the Silk Road in more than one direction.They earned their living by traveling the famous Silk Road.

The Silk Road was not a simple trading network.It passed through thousands of cities and towns.It started from eastern China, across Central Asia and the Middle East, and ended in the Mediterranean Sea.It was used from about 200 B.C.to about 1300 AD, when sea travel offered new routes(路线).It was sometimes called the world’s longest highway.However, the Silk Road was made up of many routes, not one smooth path.They passed through what are now 18 countries.The routes crossed mountains and deserts and had many dangers of hot sun, deep snow and even battles.Only experienced traders could return safe.

The Silk Road got its name from its most prized product.Silk could be used like money to pay taxes or buy goods.But the traders carried more than just silk.Gold, silver, and glass from Europe were much found in the Middle East and Asia.Horses traded from other areas changed farming practices in China.Indian merchants traded salt and other valuable goods.Chinese merchants traded paper, which produced an immediate effect on the West.Apples traveled from central Asia to Rome.The Chinese had learned to graft(嫁接)different trees together to make new kinds of fruit.They passed this science on to others, including the Romans.The Romans used grafting to grow the apple.Trading along the Silk Road led to world-wide business 2,000 years before the World Wide Web.
