Not long ago, people thought babies were notable to learn things until they were five or six months old．Yet doctors in the United States say babies begin learning on their first day of life．

Scientists note that babies are strongly influenced by their environment．They say a baby will smile if her mother does something the baby likes．A baby learns to get the best care possible by smiling to please her mother or other caregiver．This is how babies learn to connect and communicate with other human beings．

One study shows that babies can learn before they are born．The researchers placed a tape recorder on the stomach of a pregnant woman．Then, they played a recording of a short story．On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother．They did this by placing a device in the mouth of the newborn baby．

The baby would hear the story if he moved his mouth one way．If the baby moved his mouth the other way, he would hear a different story．The researchers say the baby clearly liked the story he heard before he was born．They say the baby would move his mouth so he could hear the story again and again． 

Another study shows how mothers can strongly influence social development and language skills in their children．

Researchers studied the children from the age of one month to three years．The researchers attempted to measure the sensitivity of the mothers．The women were considered sensitive if they supported their children’s activities and did not interfere unnecessarily．They tested the children for thinking and language development when they were three years old．Also, the researchers observed the women for signs of depression．

The children of depressed women did not do as well in tests as the children of women who did not suffer from depression．The children of depressed women did poorly in tests of language skills and understanding what they hear．

These children also were less cooperative and had more problems dealing with other people．The researchers noted that the sensitivity of the mothers was important to the intelligence development of their children．Children did better when their mothers were caring, even when they suffered from depression．

The First Americans
There was a time long ago when a land bridge connected Asia and North America．The first settlers in North America crossed this land bridge from what is now Siberia to Alaska．The people who made this initial crossing were probably following the animals they used for food．
Finally, the oceans rose and the land bridge between the continents disappeared．The settlers, who I shall call the "First Americans" , could not return to their homeland．  1  
For the next few thousand years, the First Americans moved south and east throughout North and South America．They made the journey all the way from Alaska to the southern tip of South America, a distance of more than 10,000 miles．    2   
In the far north, above the Arctic Circle, the First Americans became hunters of the ocean．  3 __  In the summer, they gathered berries and other plants．In the winter, they stayed in lodges much of the time preparing for the next summer．It was a hard life, but they learned to survive in these terrible conditions．
Farther south, in what is now Arizona, Utah, Colorado, and New Mexico, the First Americans became cliff dwellers．They began by living in caves that already existed in the cliffs．  4  The dwellings they built in many ways resembled today's apartment buildings．
5    They built a system of dams and canals so they could store and use water almost any time of the year．They were so successful that they could raise fruits and vegetables that were not found naturally in the desert．

The National Gallery of Art in Washington, D.C., is one of the world's greatest art museums. Millions of people have entered its doors to see paintings by the world's fine artists. But if these priceless masterpieces are to be preserved, the Gallery must protect them carefully. The Gallery's 135-man guard force has successfully prevented them from being stolen, but protecting the paintings from nature is a greater problem.

In past times, the owners of paintings did not protect them from damaging changes in humidity (湿度) and temperature. As a result, the life of these paintings were shortened. In the National Gallery, however, humidity and temperature are carefully controlled. The building is air-conditioned in summer and heated in winter. The air-conditioning and heating system are so important to the life of the painting that the Gallery has two of each system. If one should fail, the extra one can take over.

Light is another enemy of paintings. Ultraviolet rays (紫外线) in light cause paintings to fade (褪色).  Long ago, paintings often hung in dark churches and palaces. A coat of varnish (清漆) was a protection from the weak light. But when museums took over the care of many paintings, they were often hung in brighter light than before. Soon they were in danger of fading. The damaging effects of light were increased when the museums removed the varnish coating, yellowed with age.

To protect its paintings, the National Gallery put a special kind of glass in its skylights. This glass allows visible lights to enter the building but it keeps out harmful ultraviolet rays. The Gallery has also developed new and better varnishes which help to keep paintings from fading. Thanks to these new precautions, many of the world's greatest paintings are being well protected for future generations to enjoy.

A．the guard force in the National Gallery

I will never forget the year I was about twelve years old. My mother told us that we would not be _21_ Christmas gifts because there was not enough money. I felt sad and thought, “What would I say when the other kids asked what I’d  22  ?” Just when I started to  23  that there would not be a Christmas that year, three women  24  at our house with gifts for all of us. For me they brought a doll. I felt such a sense of  25  that I would no longer have to be embarrassed when I returned to school. I wasn’t  26  . Somebody had thought  27  of me to bring me a gift. 

      Years later, when I stood in the kitchen of my new house, thinking how I wanted to make my  28  Christmas there special and memorable, I  29  remembered the women’s visit. I decided that I wanted to create that same feeling of  30  for as many children as I could possibly reach.

      So I  31  a plan and gathered forty people from my company to help. We gathered about 125 orphans (孤儿) at the Christmas party. For every child, we wrapped colorful packages filled with toys, clothes, and school supplies,  32  with a child’s name. We wanted all of them to know they were  33  . Before I called out their names and handed them their gifts, I   34  them that they couldn’t open their presents  35  every child had come forward. Finally the  36  they had been waiting for came as I called out, “One, two, three. Open your presents!” As the children opened their packages, their faces beamed and their bright smiles  37  up the room. The  38  in the room was obvious, and  39  wasn’t just about toys. It was a feeling –the feeling I knew  40  that Christmas so long ago when the women came to visit. I wasn’t forgotten. Somebody thought of me. I matter.

When we can see well, we do not think about our eyes often. It is only when we can not see perfectly that we come to see how important our eyes are.

People who are nearsighted can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly.

People who are farsighted face just the opposite problem. They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses too.

Other people do not see clearly because their eyes are not exactly the right shape. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

When night falls, colors become fainter to the eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction. This is because when you turn your head, you are looking? at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they can not see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark.

A. we think about our eyes      B. we cannot see clearly

C. we wear glasses               D. we have to do much reading
