You will hear a selection of recorded materials and you must answer the questions that accompany them. There are th
2、ree parts in this section, Part A, Part B and Part C. Remember, while you are doing the test, you should first put down your answers in your test booklet, NOT on the ANSWER SHEET. At the end of the listening comprehension section, you will have 5 minutes to transfer your answers from your test bookl
3、et onto ANSWER SHEET 1. If you have any questions, you may raise your hand NOW, as you will not be allowed to speak once the test has started. Now look at Part A in your test booklet. Part A You will hear a talk about a different culture. As you listen, answer Questions 1-10 by circling TRUE or FALS
4、E. Youll hear the talk ONLY ONCE. You now have 60 seconds to read Questions 1-10. (如需获取本MP3听力录音请搜索标题名) 1. Evidence can be used to prove indirectly the existence of black hole.答案:A听力原文1-10 We cant see a black hole directly, since light cant get past the horizon. That means that we have to rely on ind
5、irect evidence to prove that black holes exist. Suppose you have found a region of space where you think there might be a black h01e. How can you check whether there is one or not? The first thing youd like to do is measure how much mass there is in that region. If youve found a large mass concentra
6、ted in a small volume, and if the mass is dark, then its a good guess that theres a black hole there. There are two kinds of systems in which astronomers have found such compact, massive, dark objects: the centers of galaxies(including perhaps our own Milky Way Galaxy) ,and X-ray-emiting binary syst
7、ems in our own Galaxy. Accoridng to a recent review by Kormendy and Richstone, eight galaxies have been observed to contain such massive dark objects in their centers. The masses of the cores of these galaxies range from one million to several billion times the mass of the Sun. The mass is measured
8、by observing the speed with which stars and gas orbit around the center of the galaxy: the faster the orbital speeds, the stronger the gravitational force required to hold the stars and gas in their orbits. These massive dark objects in galactic centers are thought to be black holes for at least two
9、 reasons. First, it is hard to think of anything else they could be: they are too dense and dark to be stars or clusters of stars. Second, the only promising theory to explain the mysterious objects known as quasars and active galaxies assumes that such galaxies have supermassive black holes at thei
10、r cores. If this theory is correct, then a large fraction of galaxies all the ones that are now or used to be active galaxies must have supermassive black holes at the center. Taken together, these arguments strongly suggest that the cores of these galaxies contain black holes, but they do not const
11、itute absolute proof. Two very recent discoveries have been made that strongly support the hypothesis that these systems do indeed contain black holes. Flint, a nearby active galaxy was found to have a water maser system(a very powerful source of microwave radiation) near its nucleus. Using the tech
12、nique of very-long-baseline interference, a group of researchers were able to map the velocity distribution of the gas with very fine resolution. In fact, they were able to measure the velocity within less than half a light-year of the center of the galaxy. From this measurement they can conclude th
13、at the massive object at the center of this galaxy is less than half a light-year in radius. It is hard to imagine anything other than a black hole that could have so much mass c6ncentrated in such a small volume. A second discovery provides even more compelling evidence. X-ray astronomers have dete
14、cted a spectral line from one galactic nucleus that indicates the presence of atoms near the nucleus that are moving extremely fast(about 1/3 the speed of light). Furthermore, the radiation from these atoms has been redshifted in just the manner one would expect for radiation coming from near the ho
15、rizon of a black hole. These observations would be very difficult to explain in any other way besides a black hole, and ff they could be verified, then the hypothesis that some galaxies contain supermassive black holes at their centers would be fairly secure. 2. Black hole possibly exists where comp
16、act mass can be found in a small volume.答案:A3. Up till now, astronomers have found two black holes.答案:B4. The eight galaxies observed are much bigger than the sun in volume.答案:B5. The stars move at a faster speed around the cores of the galaxies observed.答案:A6. Compared with the eight galaxies, the
17、suns gravitational force is so stronger.答案:B7. Astronomers believe they have found black holes in other galaxies because they can not explain what they have seen.答案:B8. The new technique helps astronomers to affirm the presence of black holes in other galaxies.答案:A9. The radiation of atoms near the
18、galactic nucleus is difficult to explain.答案:B10. No one can be certain of the presence of black hole until those ob-servations are verified.答案:APart B (如需获取本MP3听力录音请搜索标题名) 1.

He also called for a Federal government wide effor
29、t to explore how Federal programs can better support the use of technologies for lifelong learning. A few weeks later, in his state of the Union address, the president commended the Congress for passing a lifelong learning tuition tax credit which he had proposed, and he offered new initiatives to e
30、nable Americans to continue their education. In November 1997, Vice President Albert Gore, Jr. addressed a national conference on Creating a Nation of Lifelong Learners, where he spoke of the importance of lifelong learning as a key to success in Americas new economy. The Vice President announced th
31、at in 1998 the White House will convene a Summit on lifelong learning a conference where leaders from business, labor, higher education, government and philanthropy will address ways to help all Americans gain access to quality lifelong learning. Both the President and Vice President of the United S
32、tates recognize the importance of lifelong learning for the nations success, and they are working to make lifelong learning opportunities more widely available to all Americans. Today increasing numbers of Americans are engaged in lifelong learning. A 1995 survey of participation in adult education
33、found that during the 12 months preceding the study, approximately 40 percent of adults aged 17 years and older had participated in a program of adult education (excluding full-time enrollment in higher education credential programs). Adults are also going to college in larger numbers. Of the 14.3 m
34、illion students enrolled in post-secondary institutions in the fall of 1995, nearly 6 million, or 42 percent, were between the ages of 25 and 64. Between 1985 and 1995, the enrollment of students over 25 increased nearly twice as fast as the enrollment of students under 25. According to the Commissi
35、on for a Nation of Lifelong Learners, the emergence of adult learners as a major constituency in American higher education has been one of the most dramatic changes in the United States in the past 25 years. Although more adults are engaged in lifelong learning and educational opportunities have gro

However, this total represents a participation rate of only 9 percent of the adult target population of 44 million individua
37、ls aged 16 years and older who have not earned a high school diploma or equivalent and are not currently enrolled in school.
