[10:49.86]Section B
[10:51.69]Directions: In this section, you will hear 3 short passages.
[10:57.05]At the end of each passage, you will hear some questions.
[11:00.55]Both the passage and the questions will be spoken only once.
[11:04.82]After you hear a question,
[11:06.57]you must choose the best answer from the four choices marked A), B), C) and D).
[11:13.79]Then mark the corresponding letter on Answer Sheet 2 with a single line through the centre.
[11:20.02]Passage One
[11:21.45]One of the greatest mysteries of nature is the instinct to migrate.
[11:26.48]Every year, millions of creatures feel the need to migrate
[11:29.98]and most people have seen the arrival or departure of migrating flocks of birds.
[11:35.12]In England, for example, we always know when autumn is coming,
[11:39.39]because flocks of swallows sit on the telegraph wires.
[11:43.33]Migration is not only seen in birds but also in reptiles.
[11:47.37]For example, turtles, and frogs; insects, such as butterflies;
[11:52.73]and mammals, such as seals, whales and bats.
[11:56.45]Many of these creatures can find their way over long distances.
[12:00.72]And how they do it is a mystery and a wonder to everyone,
[12:04.55]especially for those of us who have difficulty even reading a map covering 100 miles.
[12:10.56]There are several suggestions about how they navigate. Firstly, it is suggested,
[12:16.58]they navigate by using stars and planets for guidance.
[12:20.30]Secondly, some people think that these migrating mammals find their way
[12:25.23]by following the pole of the earth's magnetic field.
[12:28.51]Thirdly, some people think that migrating birds,
[12:31.90]insects and animals follow a certain smell or scent.
[12:35.62]Fourthly, another group of people believe that animals migrate by recognizing the geographical features.
[12:42.84]Fifthly, some people think that animals migrate by following the changes in temperature.
[12:48.63]And finally, there are people who following suppose they migrate by following a sound.
[12:54.21]Questions 16 to 19 are based on the passage you have just heard.
[12:59.24]16. What is the sign of autumn coming in England?
[13:20.53]17. What mammals migrate according to this talk?
[13:39.64]18. Why is migration a mystery according to the talk?
[14:00.56]19. Which of the following isn't among the suggestions about how the creatures migrate?
[14:21.42]Passage Two
[14:23.72]With the introduction of radio, newspaper publishers wondered how broadcasting would affect them.
[14:30.17]Many feared that radio as a quick and easy means of keeping people informed
[14:35.53]would take the place of the newspaper industry.
[14:38.37]Others hoped that the brief newscast heard on the radio
[14:42.32]would make the listeners interested in the story
[14:45.27]so they would buy the newspaper to get more information.
[14:48.66]This second idea turned out to be closer to the truth.
[14:52.60]Radio and newspapers actually supported each other.
[14:56.86]In most cases, when one new media comes out,
[15:00.80]it will weaken the function of the former one.
[15:03.43]Take television and movies for example,
[15:06.16]with the popularization of TV, the movie industry suffered greatly.
[15:11.42]Movie attendance dropped when audience members chose to stay at home and be entertained.
[15:17.54]Likewise, when a football game was shown on TV,
[15:20.50]the stands were often empty because fans chose to watch the game at home.
[15:25.64]Many people believe that watching a game through TV
[15:29.25]will make them better observe the whole situation.
[15:32.31]Internet is very popular for the time being,
[15:35.37]will it affect the newspaper or TV industry greatly?
[15:39.42]In general, perhaps the answer is yes.
[15:42.48]Many people won't buy newspapers for they can read news and watch programs online.
[15:48.17]However, reading newspaper and watching TV have their advantages, which can not be replaced.
[15:54.52]All the media types will coexist and have impact on each other.
[15:59.22]Questions 20 to 22 are based on the passage you have just heard.
[16:04.25]20. What is the main topic of this talk?
[16:22.57]21. According to the speaker, how did the introduction of television affect movies?
[16:45.52]22. Which of the following view is true according to what the speaker said?
[17:04.42]Passage Three
[17:07.38]To us, the environment in which fish dwell often seems cold, dark and mysterious.
[17:13.29]But there are advantages to living in water.
[17:16.89]The cold and dark water played an important role in making fish what they are.
[17:21.81]One is that water doesn't change much to the sudden temperature changes in the air.
[17:26.96]Therefore it makes an excellent living place for a cold blooded animal.
[17:31.33]Another advantage is the water's ability to easily support body weight.
[17:36.26]A fish in water is almost weightless. This weightlessness in turn means two things.
[17:42.60]One, a fish can get along with a light weight and a simple bone structure.
[17:47.96]Because of water's floatation, whatever the size of the fish, it can swim very freely.
[17:54.30]Yet there is one basic difficulty to living in water the fact that it can't be pressed.
[18:00.43]For a fish to move through water, it must actually push the water aside.
[18:05.25]Most can do this by wiggling back and forth in snakelike motion.
[18:09.51]The fish pushes water aside by the forward motion of its head
[18:13.56]and with a curve of its body and its tail moving to right and left.
[18:18.16]Water helped to shape the development of fish.
[18:21.33]An irregular shape can be moved through water only with difficulty.
[18:25.81]And for this reason, fish have a basic shape that is beautifully adapted to deal with the fact
[18:32.05]that it can swim freely in the water without difficulties.
[18:36.20]Questions 23 to 25 are based on the passage you have just heard.
[18:41.35]23. What is the talk mainly about?
[19:00.62]24. What creature did the speaker compare to a fish's movement?
[19:22.11]25. What aspect of a fish does the speaker discuss in the most detail?
