13、ication and versatility, which promises to reshape our lives and our world. It is an electronic revolution of sorts, made possible by the marriage of television and computer technologies. The word “television“, derived from its Greek (tele: distant) and Latin (vision: sight) roots, can literally be

14、interpreted as sight from a distance. Very simply put, it works in this way: through a sophisticated system of electronics, television provides the capability of converting an image (focused on a special photoconductive plate within a camera) into electronic impulses, which can be sent through a wir

15、e or cable. These impulses, when fed into a receiver (television set),can then be electronically reconstituted into that same image. Television is more than just an electronic system, however. It is a means of expression, as well as a vehicle for communication, and as such becomes a powerful tool fo

16、r reaching other human beings. The field of television can be divided into two categories determined by its means of transmission. First, there is broadcast television, which reaches the masses through broad-based airwave transmission of television signals. Second, there is non-broadcast television,

17、 which provides for the needs of individuals or specific interest groups through controlled transmission techniques. Traditionally, television has been a medium of the masses. We are most familiar with broadcast television because it has been with us for about thirty-seven years in a form similar to

18、 what exists today. During those years, it has been controlled, for the most part, by the broadcast networks, ABC, NBC, and CBS, who have been the major purveyors of news, information, and entertainment. These giants of broadcasting have actually shaped not only television but our perception of it a

19、s well. We have come to look upon the picture tube as a source of entertainment, placing our role in this dynamic medium as the passive viewer.（分数：10.00）(1).What is the literal meaning of the word “television“?（分数：2.00）A.Medium of the masses.B.Sight from a distance.C.Airwave transmission.D.Vehicle f

Although Benjamin Franklin demonstrated lightning as enormous electrical discharge more than 200 years ago, many puzzles still surround this powerful phenomenon. Lightning is generated

24、 when electrical charges separate in rain clouds, though processes are still not fully understood. Typically, positive charges build at the cloud top, while the bottom becomes negatively charged. In most instances of cloud-to-ground lightning, the negatively charged lower portion of the cloud repels

25、 negatively charged particles on the grounds surfaces, making it become positively charged. The positive charge on the ground gathers at elevated points. A flow of electrons begins between the cloud and earth. When the voltage charge becomes large enough, it breaks through the insulating barrier of

26、air, and electrons zigzag earthward. We see the discharge as lightning. Lightning can occur within a cloud, between clouds, or between clouds and the ground. The first variety, intra-cloud lightning, is the most frequent but is often hidden from our view. Cloud-to-ground lightning, making up about 2

27、0 percent of lightning discharges, is what we usually see. Lightning comes in several forms, including sheet, ribbon, and ball. Intra-cloud lightning can illuminate a cloud so it looks like a white sheet, hence its name. When cloud-to-ground lightning occurs during strong winds, they can shift the l

28、ightning channel sideways, so it looks like a ribbon. The average lightning strike is more than 3 miles long and can travel at a tenth of the speed of light. Ball lightning, the rarest and most mysterious form, derives its name from the small luminous ball that appears near the impact point, moves h

29、orizontally, and lasts for several seconds. Thunder is generated by the tremendous heat released in a lightning discharge. Temperatures near the discharge can reach as high as 50,000 F within thousandths of a second. This sudden heating acts as an explosion, generating shock waves we hear as thunder

30、. About 2,000 thunderstorms are occurring in the world at any tie, generating about 100 lighting strikes every second, or 8 million daily. Within the United States, lightning strikes are estimated at 20 million a year, or about 22,000 per day. You have a l-in-600,000 chance of being struck by lightn

31、ing during your lifetime. Lightning can strike twice or more in the same spot. The Empire State Building in New York is struck by lightning about two dozen times annually.A.

35、ful Not long ago, a poll was conducted among students in a middle school. They were asked to make a choice between these two sentences“No one can be happy “and “One can be happy“. Shockingly enough, about 60 percent of the students agreed to the first statement. But to live on, wed better say to our

36、selves that there is happiness in life. 1 The more I think, the more I am convinced that if we have a right attitude towards life, our lives can surely be happy and meaningful. It is true that all people have some bitter experiences. 2 Many people admire Madam Curie, and say with a sigh, “If I could

37、 live like her, I would be the happiest person in the world.“ But if we take a close look at her life, we will find her happiness is closely connected with her misfortunes. First of all, she did not have a happy childhood. 3 In her research work, she had to sit up late night after night. She experie

38、nced many losses, tooshe lost her beloved father, her dear husband, and later her eyesight. But she never complained and never stopped working for the benefit of mankind. That is why her life was happy and meaningful. 4 Some people complain that their work is insignificant and thus their lives are m

39、eaningless. But what kind of work is significant? Worker, peasants, teachers, and scientists, they are all working for the welfare of mankind, themselves included. That is where the meaning of life lies. 5 Once a friend of mine told me he felt very wretched for having to work as a teacher. “ Our liv

40、es can be compared to candles. While giving light to others, we ourselves are burning out. Our students may become famous one day, but what will become of us? We shall only remain what we arefameless and wealthless. “ Paradoxically, I would rather think he was giving a vivid description of the noble

41、ness of a teacher. Different people may think of life differently. But of one thing I am certain: happiness never favors those who merely care about themselves, and the meaning of life cannot be understood by those who refuse to sacrifice anything for others.A. But some people seem to think little o

42、f such a life.B. She awoke to the realities of life.C. When she was in France, she studied twice as hard as others but lived a poor and simple life.D. She fought against life s bitterness and difficulties and conquered them all.E. I have been thinking of this question ever since.F. But it is through

44、sked to be 1 as citizens rather than criminals. Senator John McCain held the opinion that the country should open a 2 to citizenship to immigrants (移民) who were already in the country illegally, while other politicians 3 for stricter measuresincluding rounding up undocumented immigrants and sending

45、them back to their home countries. Canadian officials say that immigration applications continue to rise. Some want to keep the doors 4 They need the labor. About 400,000 immigrants were allowed into the country in 2005, according to the Canadian Government statistics. 5,all this growth means that c

46、ities need to adapt. New comers dont always make a smooth transition into jobs for which they are skilled. So industries are using mentoring (辅导) programs to help new 6 find proper jobs.

47、has decided to get 7 There will be no more mass amnesties (特赦) for the illegal immigrants, and anyone coming to Spain without 8 will be sent back.
