听力原文：W：(19) You are an expert on urban problem. Mr. Cross. I wonder how you would describe the characteristics of these enormous cities．
M：The first point to make is that they are different from large cities in Europe and America.
W：Surly all large cities are essentially similar．
M：It's true that all large cities experience similar problems provisioning housing and services，but the difference lies in the time factor．
W：Surly some of the cities we are considering are just as old and, in some cases，much older, than cities in the United States，for instance.
M：Very true, but the large cities of Europe and the United States grew relatively slowly．(21) London had a population of more than a million at the beginning of the nineteenth century and this number of more than eight million. And this growth was parallel to industrial growth throughout the country．The same is true of New York, for example．
W：But this is not true of Mexico city or Buenos Aires？
M：No，it is not．(20) Throughout Latin America and in parts of Asia, cities have grown much faster than industry，or agriculture for that matter．Some of these cities have quadrupled in size in less than two decades，while industrial growth over the same period may have only reached thirty to forty percent．
W：What does this mean？
M: Essentially the population growth is not equal to the number of employment opportunities. Much of the increase is due to immigration from the countryside, a movement of people in search of better conditions.

Passage One
Why don't birds get lost on their long migratory (迁徙) flight？ Scientists have puzzled over this question for many years. Now they are beginning to fill in the blanks.
Not long ago, experiments showed that birds rely on the sun to guide them during day-light hours. But what about birds that fly mainly by night？ Tests with artificial (人造的) stars have proved conclusively that certain night-flying birds are able to follow stars in their long-distance flights.
One such bird--a warbler--had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use stars for guidance. The bird's cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.
Scientists think that warblers, when flying in daylight, use the sun for guidance. But stars are apparently their main means of directed flight in the night. What do they do when stars are hidden by clouds？ Apparently, they find their way by such landmarks as mountain ranges, coast lines and river courses. But when it is too dark to see these, the warblers circle helplessly, unable to find their way.
Which of the following is NOT true about migratory birds' flight？
A．The first teacher.B．The second teacher.C．The last teacher.D．The next teacher.
