Recently government agencies in some big cities have been studying the possibility of putting a "pollution tax" on private cars. The amount of tax private car owners would have to pay would depend on the emissions levels, i. e. engine or vehicle size. This has caused quite a stir among the public. Some regard it as an effective way to control the number of cars and reduce pollution in the city. But others don't think so. What is your opinion？
Write on ANSWER SHEET THREE a composition of about 200 words on the following topic :
Should Car Owners be Taxed for Pollution？
You are to write in three parts.
In the first part, state specifically what your opinion is.
In the second part, support your opinion with one or two reasons.
In the last part , bring what you have written to a natural conclusion or a summary.

听力原文： How do the birds manage to find their way？ There seems to be no single answer: (32)they use many methods. Some we are beginning to understand; and there may be some that depend on abilities we have not yet suspected. (33) Many birds certainly follow major geographical features. Migrants follow recognized land, fly over familiar sea and arrive at their summer homes.
But all birds cannot use such straightforward methods. An Arctic sea bird, for example, has to fly at least 3,000 kilometers across the Antarctic Ocean with no land to guide it. We know that some birds flying at night, (34) navigate by the star for on cloudy nights they tend to get lost.
Day-flying birds may use the sun. If they are to do so, they must (35) have a precise sense of time. Still others appear to be able to use the earth's magnetic field as a guide. So it seems that many migrating birds must carry in their brains a clock, a compass and the memory of a map.
(33)
A．They use many different methods.
B．All birds follow major geographical features.
C．All birds use their memory of a map.
D．We have no information about this.

Not long ago, experiments showed that birds depend on the sun to guide them during day-flight hours. But what about birds that fly by night？ Tests with man-made stars have proved that certain night-flying birds are able to follow the stars in their long-distance flights.
A dove spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under a man-made star-filled sky. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the make-believe stars caused a change in the direction of his flight.
Scientists think that doves, flying ill daylight, use the sun for guidance. But the stars are obviously their most important means of navigation (or flying). What do they do when the stars are hidden by clouds？ Obviously, they find their way by such landmarks as mountains ranges, coastlines, and river courses. But when it is too dark to see these, the doves circle helplessly, unable to get their bearings.
The reason why birds don't get lost on long flight ______.
A．has been discovered recently
B．is known by everybody
C．still remains a mystery
D．has been known to scientists for years
Task 2
Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.
Why don't birds get lost on their long flights from one place to another？ Scientists have puzzled over this question for many years. Now they are beginning to fill in the blanks.

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．Some birds fly mainly by night.
B．Some birds fly mainly by day.
C．Birds depend on the sun or stars to guide them.
D．Birds like to fly during daylight hours.
