Many people believe the glare from snow causes snowblindness. Yet, dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness, when exposed to several hours of “snow light”. The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country. A man's eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain(地域). So his long look continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and eyeballs become sore and the eye muscles ache. Nature offers this discomfort by producing more and more liquid which covers the eyeball. The liquid covers the eyeball in increasing quantity until vision became not clear, and then is not easily seen and the result is total, even though not very long, snowblindness.
Experiments led the Army to a simple method of solving this problem. Scouts, ahead of a main body of troops, are trained to shake snow from evergreen bushes creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their eyes focus on a bush and have something to see. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white terrain is solved.

Staying positive through the cold season could be your best defense against getting ill, new study findings suggest.
In an experiment that exposed healthy volunteers to a cold or flu virus, researchers found that people with a generally sunny character were less likely to fall ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a “positive emotional style” can help to protect us from suffering the common cold and other illnesses.
Researchers believe the reasons may be both objective — as in happiness improving immune function — and subjective — as in happy people being less troubled by a sore throat or runny nose. “People with a positive emotional style may have different immune responses to the virus,” explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. “And when they do get a cold, they may interpret their illness as being less severe.”
Cohen and his colleagues had found in a previous study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional style itself had the effect.
For the new study, the researchers had 193 healthy adults complete standard measures of personality characteristics, self-felt health and emotional style. Those who had a tendency to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy, tense and aggressive had a negative style.
The researchers gave them nasal (鼻腔的) drops containing either a cold virus or a particular flu virus. Over the next six days, the volunteers reported on any aches, pains or sneezing they had, while the researchers collected objective data. Cohen and his colleagues found that based on objective measures of nasal troubles, happy people were less likely to develop a cold. Which is the best title for the passage? ______
| A．Stay Away from Being Negative |
| B．Positive or Negative？It’s Up to You. |
| C．Emotional Style and Flu. |

In Washington D.C., 1600 Pennsylvania Avenue is a very special address. It is the address of the White House, the home of the president of the United States.
Originally the White House was gray and was called the presidential Palace. It was built from 1792 to 1800. At this time, the city of Washington itself was being built. It was to be the nation’s new capital city. George Washington, the first president, and Pierre Charles L'Enfant, a French engineer, chose the place for the new city. L'Enfant then planned the city. The president's home was an important part of the plan.
A contest was held to pick a design for the president's home. An architect named James Hoban won. He designed a large three-story house of gray stone.
President Washington never lived in the Presidential Palace. The first president to live there was John Adams, the second president of the United States, and his wife Mrs.Adams did not really like her new house. In her letters, she often complained about the cold. Fifty fireplaces were not enough to keep the house warm.
In 1812 the United States and Britain went to war. In 1814 the British invaded Washington. They burned many buildings, including the Presidential Palace.
After the war James Hoban, the original architect, partially rebuilt the president’s home. To cover the marks of the fire, the building was painted white. Before long it became known as the White House.
The White House is one of the most popular tourist attractions in the United States. Every year more than 1.5 million visitors go through the five rooms that are open to the public.The White House was built in Washington_____.
| A．because a French engineer was invited to design it |
| B．because President George Washington liked to live in it |
| C．because the British invaders lived in it in1812-1814 |
| D．because it was to be the nation’s capital city |
The president’s home and the city of Washington were______.
| A．built by the American army | B．built by the British troops |
| C．planed by George Washington | D．planned by the French |
The original home of the president needed to be rebuilt______.
| A．because John Adams’ wife did not like it |
| B．because it was cold in winter even with 50 fireplace |
| C．because it had been burned down during the war |
| D．because George Washington was not willing to live in it |
The new presidential home was painted white to ______.
A. cover the marks of fire B. attract tourist from France

In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Bad events like "serious illness of a family member" were high on the list, but so were some helpful life-changing events like marriage.
When you take the Holmes-Rahe test you must remember that the score does not show how you deal with stress －it only shows how much you have to deal with. And we now know that the way you deal with these events dramatically (戏剧性的) affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women's magazines ran titles like "Stress causes illness".
If you want to stay physically and mentally healthy the articles said avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous , many — like the death of a loved one — are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription (处方) for staying away from chances as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The idea that all stress makes you sick also takes no notice of a lot of what we know about people. It supposes we' re all vulnerable and not active in the face of the difficult situation. But what about human ability and creativity? Many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change or challenge can lead to boredom and physical and mental pressure.

In bringing up children, every parent watches eagerly the child's acquisition (学会) of each new skill m the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.
Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe (严格的) over time of coming home at night or punctuality for meals. In general, the controls represent the needs of the parents and the values of the community as much as the child's own happiness.
As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practice what they preach (说教), their children may grow confused when they grow old enough to think for themselves, and realize they have been to some extent fooled.
A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.
