Part ⅡReading Comprehension (Skimming and Scanning) (15 minutes)Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1.For questions 1~7, markY (for YES) if the statement agrees with the information given in the passage;N (for NO) if the statement contradicts the information given in the passage;NG (for NOT GIVEN)if the information is not given in the passage.For questions 8~10, complete the sentences with the information given in the passage.The T rouble with T elevisionIt is difficult to escape the influence of television. If you fit the statistical averages, by the age of 20 you will have been exposed to at least 20,000 hours of television. Y ou can add10,000 hours for each decade you have lived after the age of 20. The only things Americans do more than watch television are work and sleep.Calculate for a moment what could be done with even a part of those hours. Five thousand hours, I am told, are what a typical college undergraduate spends working on a bachelors degree. In 10,000 hours you could have learned enough to become an astronomer or engineer. Y ou could have learned several languages fluently. If it appealed to you, youcould be reading Homer in the original Greek or Dostoyevsky in Russian. If it didn t, you could have walked around the world and written a book about it.The trouble with television is that it discourages concentration. Almost anything interesting and rewarding in life requires some constructive, consistently applied effort. The dullest,the least gifted of us can achieve things that seem miraculous to those who never concentrate onanything. But television encourages us to apply no effort. It sells us instantgratification（满意）. It diverts us only to divert, to make the time pass without pain. Television s variety becomes a narcotic（麻醉的）, nor a stimulus. Its serial, kaleidoscopic （万花筒般的）exposures force us to follow its lead. The viewer is on a perpetual guidedtour: 30 minutes at the museum, 30 at the cathedral, 30 for a drink, then back on the bus to the next attraction—except on television, typically, the spans allotted arc on theorder of minutes or seconds, and the chosen delights are more often car crashes and people killing one another. In short, a lot of television usurps（篡夺；侵占）one of the mostprecious of all human gifts, the ability to focus your attention yourself, rather than just passively surrender it.Capturing your attention—and holding it—is the prime motive of most television programming and enhances its role as a profitable advertising vehicle. Programmers live in constantfear of losing anyone s attention—anyone s. The surest way to avoid doing so is to keep everything brief, not to strain the attention of anyone but instead to provide constantstimulation through variety, novelty, action and movement. Quite simply, television operates on the appeal to the short attention span.It is simply the easiest way out. But it has come to be regarded as a given, as inherent in the medium itself; as an imperative, as though General Sarnoff, or one of the other augustpioneers of video, had bequeathed（遗留；传于）to us tablets of stone commanding that nothing in television shall ever require more than a few moments Concentration.In its place that is fine. Who can quarrel with a medium that so brilliantly packages escapist entertainment as a mass marketing tool? But I see its values now pervading this nationand its life. It has become fashionable to think that, like fast food, fast ideas are the way to get to a fast moving, impatient public.In the case of news, this practice, in my view, results in inefficient communication. I question how much of television s nightly news effort is really absorbable and understandable.Much of it is what has been aptly described as “machine gunning with scraps.”I think the technique fights coherence. I think it tends to make things ultimately boring (unless theyare accompanied by horrifying pictures) because almost anything is boring if you know almost nothing about it.I believe that TV s appeal to the short attention span is not only inefficient communication but decivilizing as well. Consider the casual assumptions that television tends tocultivate: that complexity must be avoided, that visual stimulation is a substitute for thought, thatverbal precision is an anachronism. It may be old fashioned, but I was taughtthat thought is words, arranged in grammatically precise.There is a crisis of literacy in this country. One study estimates that some 30 million adult Americans are “functionally illiterate” and cannot read or write well enough to answer thewant ad or understand the instructions on a medicine bottle.Literacy may not be an inalienable human right, but it is one that the highly literate Founding Fathers might not have found unreasonable or even unattainable. We are not only notattaining it as a nation, statistically speaking, but we are falling further and further short of attaining it. And, while I would not be so simplistic as to suggest that television is thecause, I believe it contributes and is an influence.Everything about this nation—the structure of the society, its forms of family organization, its economy, its place in the world—has become more complex, not less. Y et itsdominating communications instrument, its principal form of national linkage, is one that sells neat resolutions to human problems that usually have no neat resolutions. It is allsymbolized in my mind by the hugely successful art form that television has made central to the culture, the 30 second commercial: the tiny drama of the earnest housewife whofinds happiness in choosing the right toothpaste.When before in human history has so much humanity collectively surrendered so much of its leisure to one toy, one mass diversion? When before has virtually an entire nationsurrendered itself wholesale to a medium for selling?Some years ago Y ale University law professor Charles L. Black. Jr. wrote: “… forced feeding on trivial fare is not itself a trivial matter. I think this society is being forced, fed with trivialfare, and I fear that the effects on our habits of mind, our language, our tolerance for effort, and our appetite for complexity are only dimly perceived. If I am wrong, we will havedone no harm to look at the issue skeptically and critically, to consider how we should be residing it. I hope yo u will join with me in doing so.”注意：此部分试题在答题卡1上作答；8~10题在答题卡1上。

Part I Writing （写作参考范文）
Dear Zhang Hong: Congratulations on your successful admission into Renmin University. I’d like to share with you some of my experience and opinions about university study. University study differs greatly from high school in the following aspects. Firstly, university allows more freedom and expects students to take responsibility for their own decisions, actions and lifestyles. There are fewer rules and regulations imposed in university, and professors seldom take attendance in class. However, students are held accountable for their own behavior. The second major difference exists in the way of teaching. We were supposed to memorize a lot of knowledge and facts in high school while the university teachers aim to develop students’ critical thinking ability and practical skills. For example, our English teacher encourages us to practice using the language constantly and critique literary works. Of course, different teaching approaches and focuses lead to our different learning strategies in university. I remember having a hard time adapting to the new environment in the first semester. In order to meet the course requirements and deadlines, I set up and stick to my own schedule. Whenever learning something new, I always question myself the why and the how. Besides reading and thinking independently, I find talking and sharing with others quite helpful for deeper understanding of the new concepts and information. Good luck and best wishes for your university study!
