Now satellites are 36 to forecast（预报）the weather. They are in space, and they can 37 any part of the world. The satellites take pictures of the atmosphere（大气），38 this is where the weather forms（形成）. They send these 39 to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say 40 the weather will change.Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier 41 . Perhaps they may find that the clouds have changed during the last few hours. This may mean that the 42 on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.So the weather satellites are a great 43 to the meteorologists. 44 __satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may 45 forecast the weather for a week or more ahead（提前）.36.________________A. help B. to help C. helped D. helping

第一篇Computer LiteracyThere is no denying that students should learn something about how computers work,just as we expect them at least to understand that the internal-combustion engine（内燃机）has something to do with burning fuel, expanding gases and pistons（活塞）being driven. For people should have some basic idea of how the things that they use do what they do.Further,students might be helped by a course that considers the computer's impact on society. But that is not what is meant by computer literacy. For computer literacy is not a form of literacy（读写能力）。It is a trade skill that should not be taught as a liberal art.Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers.But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun,and while our society needs some people who are experts at it,the same is true of auto repair and violin-making.Learning how to use a computer is not that difficult,and it gets easier all the time as programs become more"user-friendly".Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen.What does the phrase"learning to use a computer" mean? It sounds like"learning to drive a car",that is,it sounds as if there is some set of definite skills that,once acquired,enable one to use a computer.In fact,"learning to use a computer" is much more like"learning to play a game",but learning the rules of one game may not help you play a second game,whose rules may not be the same. There is no such a thing as teaching someone how to use a computer. One can only teach people to use this or that program.To be the competent citizens of tomorrow,people should_______.A:try to lay a solid foundation in computer scienceB:be aware of how the things that they use do what they do,C:learn to use a computer by acquiring a certain set of skillsD:understand that programming a computer is more essential than repairing a car

单选题Passage3 Questions 11 to 15 are based on the following passage. Many of the most damaging and life threatening types of weather, such as torrential rains and severe thunderstorms, begin quickly, strike suddenly, and disappear rapidly, destroying small regions while leaving neighboring areas untouched. (79) Conventional（普通） computer models of the atmosphere have limited value in predicting short-lived local storms because the available weather data are generally not detailed enough to allow computers to see clearly the small atmospheric changes that come before these storms.In most nations, for example, weather-balloon observations are taken just once ever3r twelve hours at location 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 nowcasts, was impracticable. The cost of equipping 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 beyond overcoming.Fortunately, scientific and technological advance have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observations over large regions at a relatively low cost. Communication satellites can transmit data around the world cheaply and immediately, and modern computers can quickly compile and analyze this large volume of weather information. (80) Meteorologists（气象学家）and computer scientists now work together to design computer programs and video equipment capable of transforming r.aw 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, nowcasting is becoming a reality.14 Things have been changed by the following EXCEPT______.A

问答题Practice 4 Read the following text(s) and write an essay to 1) summarize the main points of the text(s), 2) make clear your own viewpoint, and 3) justify your stand. In your essay, make full use of the information provided in the text(s). If you use more than three consecutive words from the text(s), use quotation marks (“ ”). You should write 160—200 words on the ANSWER SHEET. The information and computer technologies have boosted the efficiency and convenience of people’s work and study. Their application in school education has provided teachers and students with new approaches to knowledge and information. There is a heated discussion about whether computers will replace teachers. The following are the supporters’ and opponents’ opinions. Supporters: With the advanced computer and Internet, children can get the learning material whenever they want. Online teaching is becoming more and more popular that students can get planned lessons online. After each class, there is homework for them to do. Both the learning and practice can be done on computers. From computers students can learn something that they are interested in so that they won’t be restricted to the subjects that they are taught at school. Therefore, students will have the opportunity to achieve an all-around development. Opponents: Students need to communicate with teachers and get instructions from them whenever they have troubles in their study. Computers are only cold devices that will affect children’s ability to have face-to-face communication. Education is not only about imparting the knowledge, but also being a useful person. So students need to learn some useful values to be a good person which sometimes cannot be easily learned from computers. Children who use computer will learn to communicate with machines instead of people. There is a risk that they will be a generation of social illiterates.
