Television hasnt been with us all that long, but we are already beginning to forget what the world was like without it,

10、Before we admitted the one-eyed monster into our homes we never found it difficult to occupy our spare time. We used to enjoy civilized pleasures. For instance, we used to have hobbies, we used to entertain our friends and be entertained by them, we used to go outside for our amusements to theatres,

11、 cinemas, restaurants and sporting events, We even used to read books and listen to music and broadcast talks occasionally. All that belongs to the past. Now all our free time is regulated by the “goggle box“. We rush home or gulp down our meals to be in time for this or that programme. We have even

12、 given up sitting at table and having a leisurely evening meal, exchanging the news of the day. A sandwich and a glass of beer will do anything, providing it doesnt interfere with the programme. The monster demands absolute silence and attention. If any member of the family dares to open his mouth d

13、uring a programme, he is quickly silenced.Whole generation are growing up addicted to the telly. Food is left uneaten, homework undone and sleep is lost, The telly is a universal pacifier. It is now standard practice for mother to keep the children quiet by putting them in the living room and turnin

14、g on the set. It doesnt mater that the children will watch rubbishy commercials or spectacles of sadism(性虐狂)and violenceso long as they are quiet.There is a limit to the amount of creative talent available in the world, Every day, television consumes vast quantities of creative work, That is why mos

15、t of the programmes are so bad : it is impossible to keep pace with the demand maintain high standards as well. When millions watch the same programme, the whole world becomes a village, and society is reduced to the conditions which obtain in pre-literate communities (有文字之前的时期). We become utterly d

16、ependent on the two most primitive media of communication: pictures and the spoken work.Television encourages passive enjoyment. We become content with second-hand experiences. It is so easy to sit in our armchair watching others working. Little by little “television“ cuts us off from the real world

17、. We get so lazy, we choose to spend a fine day in semi-dark-ness, glued to our sets, rather than go out into the world itself, Television may be a splendid medium of communication, but it prevents us from communicating with each other. We only become aware how totally irrelevant television is to re

24、 say they have discovered hints of alien life on the Saturns moon. The discovery of a sort of life was announced after researchers at the US space agency, NASA, analyzed data from spacecraft Cassini, which pointed to the existence of methane-based form of life on Saturns biggest moon.Scientists have

25、 reportedly discovered clues showing primitive alien beings are “breathing“ in Titans dense atmosphere filled with hydrogen.They argue that hydrogen gets absorbed before hitting Titans planet-like surface covered with methane lakes and rivers. This, they say, points to the existence of some “bugs“ c

26、onsuming the hydrogen at the surface of the moon less than half the size of the Earth.“We suggested hydrogen consumption because its the obvious gas for life to consume on Titan, similar to the way we consume oxygen on Earth,“ says NASA scientist Chris McKay. “If these signs do turn out to be a sign

27、 of life, it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth. “To date, scientists have not yet detected this form of life anywhere, though there are liq-uid-water-based microorganisms on Earth that grow well on methane or produce

28、it as a waste product. On Titan, where temperatures are around 90 Kelvin (minus 290 degrees Farenheit), a methane-based organism would have to use a substance that is liquid as its medium for living processes, but not water itself. Water is frozen solid on Titans surface and much too cold to support

29、 life as we know it.Scientists had expected the Suns interactions with chemicals in the atmosphere to produce a coating of acetylene on Titans surface. But Cassini detected no acetylene on the surface.The absence of detectable acetylene on the Titans surface can very well have a non-bio-logical expl

30、anation, said Mark Allen, a principal investigator of the NASA Titan team.“Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed,“ Alien said. “We have a lot of work to do to rule out possible non-biological expla

31、nations. It is more likely that a chemical process, without biology, can explain these results. /（分数：15.00）(1).What have scientists found about Saturn?（分数：3.00）A.They have found methane-based life on Saturn.B.They have found a new moon orbiting Saturn.C.They have found methane-based life on Titan.D.

32、They have found earthlike life on a Saturns moon.(2).What do scientists say about Titan?（分数：3.00）A.Water on Titan exists in the form of ice.B.There are life clues there.C.Rivers and lakes there contain life forms.D.There is acetylene ther(3).To date, scientists have not yet detected this form of lif

33、e. (paragraph 5) What does “this form of life“ refer to?（分数：3.00）A.Gas-based life.B.Methane-based life.C.Water-based life.D.Liquid-water-based microorganisms.(4).What can be inferred from what Allen said?（分数：3.00）A.Scientists have different arguments over whether there is life on Titan.B.Scientists

36、ain nasty. That compulsion has resulted in roboticsthe science of conferring various human capabilities on machines. And if scientists have yet to create the mechanical version of science fiction, they have begun to come close.As a result, the modern world is increasingly populated by intelligent gi

37、zmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by

38、 tireless robo-drivers. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracyfar greater precision that highly skilled physicians can achieve with their hands a

39、lone.But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselvesgoals that pose a real challenge. “While we know how to tell a robot to handle a specific error, “says Dave Lavery,

40、manager of a robotics program at NASA, “we cant yet give a robot enough common sense to reliably interact with a dynamic world. “Indeed the quest for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transis

41、tor circuits and microprocessors might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries.What they found, in attempting to model thought, is that the human brains roughly one hundred billion nerve cells a

42、re much more talentedand human perception far more complicated-than previously imagined. They have built robots that can recognize the error of a machine panel by a fraction of a millimeter in a controlled factory environment. But the human mind can glimpse a rapidly changing scene and immediately d

43、isregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of winding forest road or the single suspicious face in a big crowd. The most advanced computer systems on Earth cant approach that kind of ability, and neuroscientists still dont know quite how we do it.（

44、分数：15.00）(1).Human ingenuity was initially demonstrated in _.（分数：3.00）A.the use of machines to produce science fictionB.the wide use of machines in manufacturing industryC.the invention of tools for difficult and dangerous workD.the elites cunning tackling of dangerous and boring work(2).The word “g

47、 monkey to argue that robots are _.（分数：3.00）A.expected to copy human brain in internal structureB.able to perceive abnormalities immediatelyC.far less able than human brain in focusing on relevant informationD.best used in a controlled environment七、第三篇(总题数：1，分数：15.00)The Rising Oil PriceCould the ba

48、d old days of economic decline be about to return? Since OPEC agreed to sup-ply-cuts in March, the price of crude oil has jumped to almost $ 26 a barrel, up from less than $10 last December. This near-tripling of oil prices calls up scary memories of the 1973 oil shocks resulted in double-digit infl

49、ation and global economic decline. So where are the headlines warning of gloom and doom this time?The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the dame time as winter grips the northern hemisphere, could push the price higher still in the short term.Yet there are good reasons to expect the economic consequences now to be les
