Many of the most damaging and life threatening types of weather torrential rains, severe thunderstorms, and tornadoes(龙卷风,)--begin quickly, strike suddenly, and disappear rapidly, destroying small regions while leaving neighboring areas untouched. Such event as a tornado struck the north eastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $ 250 million, the highest ever for any Canadian storm.
Conventional computer models of the atmosphere have limited value in predicting short lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the subtle (微妙的)atmospheric changes that come before these storms. In most nations, for example, weather - balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.
Until recently, the observation intensive approach needed for accurate, very short - range forecasts, or "Now casts", was not feasible. The cost of e quipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were hard to overcome. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modem computers can quickly compile and analyze this large volume of weather information. Meteorologists(气象学者) and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, now casting is becoming a reality.

The banana "tree" is actually not a real tree. This is because there is no wood in the stem(树干) rising above the ground. The stem is made up of leaves growing very close together, one inside the other. The leaves spread out at the top of the stem and rise in the air.
Banana plants need a lot of care and attention. They must be provided with water if the normal rainfall doesn't supply enough. The area around the plants must be kept free of weeds and grass.
About nine or ten months after planting, a flower appears on the banana plant. This flower is at the end of a long stalk(茎), which grows from the base up through the center of the stem and turns downward when it comes out from the top. Small bananas form. on this flower stalk as it grows down- ward. Bananas really grow upside down. As the small bananas form. on the stalk, they point down- ward, but as they grow they mm and point upward.
Bananas are harvested while they are still green. Even when they are to be eaten where they are grown, they are not allowed to ripen on the plant. A banana that turns yellow on the plant loses its taste.
The first paragraph in the text mainly discusses ______.
A．why the banana tree is not a tree
B．how the banana grows on the stem
C．why the stem of the tree is wood
D．how the leaves grow out of the stem

I used to think education was the most important thing in my life. Recently my attitude has begun to change, although I still hold that it is essential for everyone in the world today. As a top junior student in my college, I was asked to make a speech on how to learn English well. Standing in front of the audience and facing so many freshmen, I was trembling. I didn&39;t remember any word that I had prepared. I ran out of the conference room without finishing my speech, leaving everyone puzzled. I cried that night in my room, feeling that I was a loser. Studying takes so much of my time that I feel unable to really develop myself. I am just storing knowledge; yet fail to communicate with others. I have received many awards in school, but they don&39;t necessarily reflect anything about me. I don&39;t know how to socialize. When I leave school I fear I will be of no use to society.
I realize that everyone has her or his own way of living. I want to change my lifestyle. Of course I will keep studying. Yet I plan to look for a part-time job, which might turn out to be a good chance to get to know society. I still believe that working my hardest does make me happy. I will still stay on in college, but I will not allow it to shelter me from the real world.
