Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks’ time. Ten inches of rain may be enough for many plants to survive if the rain is spread throughout the year. If it falls within one or two months and the rest of the year is dry, those plants may die and a desert may form.
Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes（沙丘）are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.
There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs（悬崖）and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing—very, very slowly—as these forces of nature continue to work on the rock.
Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.Many plants may survive in deserts when ________.
| A．the rain is spread out in a year | B．the rain falls only in a few weeks |
| C．there is little rain in a year | D．it is dry all the year round |
Sand dunes are formed when _______.
| A．sand piles up gradually | B．there is plenty of rain in a year |
| C．the sea has dried up over the years | D．pieces of rock get smaller |
The underlined sentence in the third paragraph probably means that in a desert there is ______.
| A．too much sand | B．more sand than before |
| C．nothing except sand | D．something else besides sand |
It can be learned from the text that in a desert _______.
| A．there is no rainfall throughout the year |
| B．life exists in rough conditions |
| C．all sand dunes are a few feet high |
| D．rocks are worn away only by wind and heat |

Can trees talk? Yes --- but not in words. Scientists have reason to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree (柳树) attacked in the woods by caterpillars (毛毛虫) changed the chemistry of its leaves and made them tasteless so that the caterpillars got tired of the leaves and stopped eating them. The even more astonishing, the tree sent out a special vapor--- a signal causing its neighbors to change the chemistry of their own leaves and make themselves taste also terrible.
Communication, of course, doesn’t need to be always in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar (花蜜) for honey. So shy shouldn’t trees have ways of sending messages?

People think being an artist must be a wonderful way to earn one's living. Of course, there are lots of great things about working for oneself, at home alone. What I really like is that nobody tells me what time to start in the morning, what to wear; or whether I can take the afternoon off and go to a football match.
But then, I have no one to chat with when I'm bored, no one to discuss last night's match with during the lunch-hour. Sure, I can spend the afternoon doing something I enjoy like swimming, walking the dog, or even sleeping, if I choose. But the work will still be there when I do finally get back home, and it's still got to be finished in time. Unfortunately, working at home means that people can always find me, whether I’m bored or not and once I’ve answered the doorbell, it's too late——my thoughts have been interrupted. No one would dream of calling if I worked in an office, but in an office I find myself making cups of coffee and listening to friends' troubles. As they talk, my ideas disappear and I feel increasingly stressed thinking of my work waiting to be done.

It was a warm April day when a big fat envelope came in the mail from the only college I had ever imagined attending. I tore open the packet. My eyes were fixed on the word "congratulations". I don't remember ever smiling so wide.
Then I looked at my financial (财政的) package. The cost of Dream School's tuition( 学费), room and board was around. $40,000—an impossible sum! How could I afford to attend? What good reasons did I have to go there when three other fine colleges were offering me free tuition? My other choices were good, solid schools even if they weren't as famous as my first choice.
In my mind, attending my dream university would be the only way to realize my dream of becoming a world-class writer. My parents understood how I felt. They told me that even though it would be a financial problem, I could go wherever I would be happiest. But as I was always careful with money, I wasn't sure what to do.
One of the schools that offered me a full ride had an informational dinner one night in the spring. Considering my parents' financial difficulties, I decided to drive the 45 minutes and attend. At first, all I’d planned to do was smile politely, eat free food, listen quietly. But I surprised myself.
At dinner the president of the university talked about the wonderful, activities on campus ( 校园 ) including guest lectures and social gatherings. He also made it perfectly clear that free food would be offered at all future events. He continued with explanations of professors, class sizes, activities, and sporting events on campus. As he spoke, I began to realize that this school, though not as good as my first choice, might be the best one for me. It seemed small yet with many great programs. It seemed challenging yet caring.
As the president ended his speech, we clapped politely and pushed back our chairs. As I walked out that door, a feeling of to comfort washed over me. Looking at the campus that night, I realized that I would be spending the next four years right there.
In all honesty, my university is not as well-known as my "dream" university. However, it turned out to be the right choice of schools for me.
62. How did he author feel when he started to read the letter?

C. He was worried about the money D. He was uncertain which school to go.
63. We can learn from the passage that the parents were_______.

A. would pay for transport to the school
B. would show me around the campus
C. would offer free meals at all events
D. would charge me nothing for tuition

B. You should consider comfort in your choice of schools.
C. You should try your best to attend your dream school.
D. Your choice of schools should be based on their fame.

A
It is natural that young people are often uncomfortable when they are with their parents. They say that their parents don't understand them. They often think that their parents are out of touch with modem ways; that they are too serious and too strict with their children; and that they seldom give their children a free hand.
It is true that parents often find it difficult to win their children's trust and they tend to forget how they themselves felt when young.
For example, young people like to act on the spot without much thinking. It is one of their ways to show that they have grown up and they can face any difficult situation. Older people worry more easily. Most of them plan things ahead, at least in the back of their minds, and do not like their plans to be upset by something unexpected.
When you want your parents to let you do something, you will have better success, if you ask before you really start doing it.
Young people often make their parents angry with their choices in clothes, in entertainment and in music. But they do not mean to cause any trouble—— it is just that they feel cut off from the older people's world, into which they have not yet been accepted. That's why young people want to make a new culture of their own. And if their parents do not like their music or entertainment or clothes or their ways of speech, this will make the young people extremely happy.
Sometimes you are so proud of yourself that you do not want your parents to say "yes" to what you do. All you want is to be left alone and do what you like. It is natural enough, after being a child for so many years, when you were completely under your parents' control.
If you plan to control your life, you'd better win your parents over and try to get them to understand you. If your parents see that you have a high sense of responsibility, they will certainly give you the right to do what you want to do.

One of the goals of American education officials is to have all public schools connected to the Internet computer system and have computer for all students .Government studies show that in 1994 only thirty-five percent of American public schools were connected to the Internet .Last year, that number reached eighty-nine percent.
Virginia Polytechnic Institute of State University is a large university in the southern state of Virginia. Officials at Virginia Tech say computers are very important to a student’s education. All students at Virginia Tech have been required to have a computer since 1998.
Each student’s living area at Virginia Tech has the necessary wires to link a computer to the Internet .The students can send and receive electronic mail, use the World Wide Web part of the Internet and link with other universities, all without leaving their room .They can also use their computers to send electronics copies of their schoolwork to their teachers .And they can search for books in the school’s huge library.
Most major American universities and colleges strongly urge or require new students to have a computer. Most colleges and universities also have large rooms where students can use computers for class work.
American high schools also have computers .Many have their own areas on the World Wide Web. If you have a computer you can learn about Fremont Union High School in Sunnyvale, California, for example .Its Web site provides information about the school, the teachers and their electronic mail addresses .It also lists student events and organizations.
Young children also use computer in school. Smoketree Elementary School in Lake Havasu, Arizona has given us a good example .The school also has a World Wide Web site .It tells about the school and the teachers and has a area for young children .These young children use computer in school to learn numbers and letters .They also learn how to use the computer they will need later in their education.
