8、ht on the problem we are investigating.Task III Reading Comprehension Directions: There are 9 short passages in this section. Each passage is followed by some questions. There are four choices for each question and you should decide on the best choice Passage One The human brain contains 10 thousand

9、 million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace, we can be less sure. Quite soon, in onl

10、y 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software or by altering the architecture, but that, too, will happen. I think it certain that in deca

11、des, not centuries, machines of silicon will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbons long control. And we will no longer be abl

12、e to claim ourselves to be the finest intelligence in the known universe. As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, har

13、mful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our

14、power. 1. In what way can we make a machine intelligent? A) By making it work in such environments as deserts, oceans or space. B) By working hard for 10 or 20 years. C) By either properly programming it or changing its structure. D) By reproducing it. 2. What does the writer think about machines wi

15、th human-like ability? A) He believes they will be useful to human beings. B) He believes that they will control us in the future. C) He is not quite sure in what way they may influence us. D) He doesnt consider the construction of such machines possible. 3. The word carbon (Sentence 4, Paragraph 2)

16、 stands for _ A) intelligent robots B) a chemical element C) an organic substance D) human beings 4. A robot can be used to expand our frontiers when _ A) its intelligence and cost are beyond question B) it is able to bear the rough environment C) it is made as complex as the human brain D) its arch

17、itecture is different from that of the present ones 5. It can be inferred from the passage that _. A) after the installation of a great number of cells and connections, robots will be capable of self-production B) with the rapid development of technology, people have come to realize the possibility

18、of making a machine with human-like ability C) once we make a machine as complex as the human brain, it will possess intelligence D) robots will have control of the vast, man-made world in space Passage Two A new study by US researchers suggests that the ocean, in particular the epic ebbs and flows

19、of sea level and sediment（沉积) over the course of geological time, is the primary cause of the worlds periodic mass extinctions over the past 500 million years. The expansions and contractions of those environments have pretty profound effects on life on Earth, says assistant professor of geology and

20、 geophysics at the University of Wisconsin-Madison, who is the author of the new report published in the latest issue of the journal Nature. In short, says the professor, changes in ocean environments related to sea level exert a driving influence on rates of extinction, which animals and plants sur

21、vive or vanish, and generally determine the composition (结构）of life in the oceans. Since the advent of life on Earth 3.5 billion years ago, scientists think there may have been as many as 23 mass extinction events. During the past 540 million years, there have been five well-documented mass extincti

22、ons, primarily of marine plants and animals, with as many as 75 95 percent of species lost. For the most part, scientists have been unable to pin down the causes of such dramatic events. In the case of the demise (消亡)of the dinosaurs, scientists have a smoking gun, an impact crater (火山口) that sugges

23、ts dinosaurs were wiped out as the result of a large asteroid （行星）crashing into the planet. But the causes of other mass extinction events have been murky, at best. Arnold Miller, a professor of geology at the University of Cincinnati, says the new study is striking because it establishes a clear re

24、lationship between the tempo of mass extinction events and changes in sea level and sediment. The new Wisconsin study, Peters says, does not preclude (排除)other influence upon extinction such as physical events like volcanic eruptions or killer asteroids, or biological influences such as disease and

25、competition among species. But what it does do, he argues, is to provide a common link for mass extinction events over a significant stretch of Earth history. 6. What does the phrasethose environment refer to in the beginning of the second paragraph？ A) Periodic mass extinctions. B) Flows of sea lev

26、el. C) Sediment. D) Ocean environments. 7. According to the passage, most of the mass extinctions are A) well-known to scientists B) adequately-documented C) well-recorded in the past 540 million years D) not well-recorded 8. 1t can be inferred from the passage that _ . A) scientists have found out

27、the causes of most mass extinctions B) the asteroid crashing into the Earth is pinned down as the cause of most mass extinctions C) most mass extinctions are caused by impact craters such as the vanishing of dinosaurs D) the causes of most mass extinctions are still unknown to scientists 9. The new

28、study is quite impressive as. A) it provides the causes of mass extinctions B) it suggests the causes of mass extinctions and the changes of ocean environments C) it excludes other influences on extinctions D) it involves physical and biological influences on extinctions 10. According to the passage

29、, the authors attitude is A) negative B)critical C)positive D)satiric Passage ThreeThe most noticeable trend among todays media companies is vertical integration.an attempt to control several related aspects of the media business at once, each part helping the other. Besides publishing magazines and

30、 books, Time Warner, for example, owns Home Box Office (HBO), Warner movie studios, various cable TV systems throughout the United States and CNN as well. The Japanese company Matsushita owns MCA Records and Universal Studios and manufactures broadcast production equipment. To describe the financial

31、 status of todays media is also to talk about acquisitions. The media are buying and selling each other in unprecedented numbers and forming media groups to position themselves in the marketplace to maintain and increase their profits. In 1986, the first time a broadcast network had been sold, two n

32、etworks were sold that year 一ABC and NBC. Media acquisitions have skyrocketed since 1980 for two reasons. The first is that most big corporations today are publicly traded companies, which means that their stock is traded on one of the nations stock exchanges. This makes acquisitions relatively easy. A media company that wants to buy a publicly owned company can buy that companys stock when the st
