2、chnology has improved television. From the silent film centuries ago to three-dimensional videos, technology also changed the role TV sets have played in peoples daily life. Developments in electronic circuits have resulted in TV sets that have sharper pictures, brilliant colors and clearer sound. F

3、rom the smallest portables to wide-screen home theater systems, televisions continue to work better and better as visual innovations are introduced. In addition, various TV programs, from current news to entertainment programs, from talk shows to TV series, all have greatly enriched peoples leisure

4、life. When assessing the impact that certain media have on public audiences, we must recognize that TV is the more “socially accepted“ media with greater appeal to us than radio. So is there anyone who can deny the importance of TV even in this fast- developed century? Unfortunately, a televisions p

5、icture is only as good as the broadcast its receiving, and even the worlds best televisions cannot make up for a weak or distorted signal. Antenna technology has not kept pace with television design, and the rabbit ears from the 1950s are not far removed from whats available today. Well, theres fina

6、lly been a quantum leap in the design of antennas, and its the result of two patented components developed by scientists. These improvements are the secret behind Emersons revolutionary new antennas.Cable subscription solves the problem of getting the signal to your television, but storms and other

7、factors can result in cable outages. If you prefer not to pay the rising monthly fees for cable or live in an area where its not available, your picture is likely to be weak, undefined and distorted.One way to improve your reception would be to mount a large antenna on you roof. Unfortunately, most

8、roof antennas are not particularly pleasing to the eye and may even be prohibited in the area where you live. Rabbit ear antennas dont improve your picture to any great degree and make your room look like something from an earlier decade. Most antennas need to be aimed at the source of the broadcast

9、 and require tuning mechanisms to pick up the signal dearly.Whether you live miles out in the country or in a concrete building next door to a broadcast tower, bad reception can rob you of the definition and color you were intended to see. The Optima antenna gives you the signal-grabbing power of a

10、large antenna in an unobvious, low-profile size.In the past, creating an antenna with optimal (最佳的) reception meant making it big, with a large amount of surface area. This resulted in products that were large and unattractive or small and ineffective. Either way, the aesthetic look of your room or

11、house suffered. Research and development tended to focus on the television, not on signal reception.until now.Recently, a brilliant scientist in Colorado developed an antenna that would maximize reception without being overly conspicuous. Emerson, a leader in electronic technology, has now made this

12、 innovation available to the public.At a lab in Colorado, they developed two patented design improvements that made the Optima antenna possible. First, they created a flexible circuit board with a serpentine (弯曲的) antenna, resulting in a large surface area confined to a small space. Second, they dev

13、eloped a technique that converts the copper shielding on the attached cable to an additional signal receiver. This greatly enhances the antennas reception power and allows you to tune the antenna by simply moving the cable! The antenna works best at a range of up to 30 miles from the signal source.

14、We recommend an amplifier for reception up to 45 miles away. Ask your representative for details.The handmade assembly is encased in aircraft-grade plastic and high-density foam. The weather-resistant cover is a neutral white and can be painted to match the color of the house or room. Plus, the omni

15、 directional (全方位的) design allows you to mount the unit anywhere you please. The Optimas universal design makes it adaptable to any component, and installation is a snap (迅速，容易).

30、_填空项 1:_填空项 1:_九、Section B(总题数：0，分数：0.00)十、Passage One(总题数：1，分数：44.50)Humans are forever forgetting that they cant control nature. Exactly 20 years ago, a magazine cover story announced that “scientists are on the verge of being able to predict the time, place and even the size of earthquakes“. The

31、people of quake-ruined Kobe learned last week how wrong that assertion was.None of the methods praised two decades ago have succeeded. Even now, scientists have yet to discover a uniform warning signal that precedes all quakes, let alone any sign that would tell whether the coming quake is mild or k

32、iller. Earthquake formation can be triggered by many factors, says Hiroo Kanamori, a seismologist (地震学家) at the California Institute of Technology. So, finding one all-purpose warning sign is impossible. One reason: Quakes start deep in the earth, so scientist cant study them directly.If a quake pre

33、cursor (预兆) were found, it would still be impossible to warn humans in advance of all dangerous quakes. Places like Japan and California are filled with hundreds, if not thousands, of minor faults. It is impossible to place monitoring instruments on all of them. And these inconspicuous sites can be

34、just as deadly as their better-known cousins like the San Andreas. Both the Kobe and the 1994 Northridge quakes occurred on small faults.Prediction would be less important if scientists could easily build structures to withstand every new quake reveals unexpected weaknesses in “quake-resistant“ stru

35、cture, says Terry Tullis, a geophysical at Brown University. In Kobe, for example, a highway that opened only last year was damaged.In the Northridge earthquake, on the other hand, well-built structures generally did not collapse. But engineers have since found hidden problems in 120 steel-frame bui

36、ldings that survived. Such structures are supposed to sway with the earth rather than crumple (崩溃). They may have swayed, but the quake also unexpectedly weakened the joints in their steel skeletons. If the shaking had been longer or stronger, the buildings might have collapsed.A recent report in Sc

37、ience adds yet more anxiety about life on the fault lines. Researchers can computer simulations to see how quake-resistant buildings would fare in a moderate-size tremor, taking into account that much of a quakes energy travels in a large “pulse of focused shaking“. The results: Both steel-frame bui

38、ldings and buildings that sit on insulating rubber pads suffered severe damage.More research will help experts design stronger structures and possibly find quake pressures. But it is still a certainty that the next earthquake will prove once again that every fault cannot be monitored and every highw

39、ay cannot be completely quake-proofed.（分数：44.50）(1).Which of the following statements is NOT true?（分数：8.90）A.Scientists have not discovered one single warning sign for all quakes.B.Scientists have not yet discovered any sign that would tell the size of quakes.C.Scientists claimed that they had found

40、 some methods of predicting earthquakes, but they didnt work.D.The methods scientists boasted of 20 years ago of predicting quakes didnt produce desired results.(2).According to the passage, quakes _.（分数：8.90）A.can in no way be studied fullyB.can be warned of beforehandC.can trigger minor faultsD.on

41、 small faults cannot possibly be as deadly as those best known quakes(3).It is implied in the passage that _.（分数：8.90）A.well-erected structures do not collapseB.the existent quake-resistant buildings need to be redesignedC.steel-frame buildings survive any earthquakesD.seismic (地震的) engineering has

42、improved well enough for structures to resist quakes(4).The best tide for this passage could be _.（分数：8.90）A.“Nature Is Beyond Humans Control“B.“No Method or Stronger Structures Are Founds to Predict and Withstand Quakes“C.“Cant We Predict Earthquakes?“D.“Earthquake, Hard to Predict!“(5).It is impos

43、sible to warn of all dangerous quakes in advance because _.（分数：8.90）A.small faults can trigger just as fatal quakesB.nothing is found that precedes and shows quakes comingC.no structures will withstand quakesD.all of the above十一、Passage Two(总题数：1，分数：44.50)Concern with money, and then more money, in

44、order to buy the conveniences and luxuries of modern life, has brought great changes to the lives of most Frenchmen. More people are working than ever before in France. In the cities the traditional leisurely midday meal is disappearing. Offices, shops, and factories are discovering the great effici

45、ency of a short lunch hour in company lunchrooms. In almost all lines of work emphasis now falls on ever-increasing output. Thus the “typical“ Frenchman produces more, earns more, and buys more consumer goods than his counterpart of only a generation ago. He gains in creature comforts and ease of li

46、fe. What he loses to some extent is his sense of personal uniqueness, or individuality.Some say that France has been Americanized. This is because the United States is a world symbol of the technological society and its consumer products. The so-called Americanization of France has its critics. They

47、 fear that “assembly-line life“ will lead to the disappearance of the pleasures of the more graceful and leisurely (but less productive) old French style. What Mil happen, they ask, to taste, elegance, and the cultivation of the good things in life - to joy in the smell of a freshly picked apple, a

48、stroll by the river, or just happy hours of conversation in a local card?Since the late 1950s life in France has indeed taken on qualities of rush, tension, and the pursuit of material gain. Some of the strongest critics of the new way of life are the young, especially university students. They are concerned with the future, and they fear that France is threatened by the triumph of t
