The Hong Kong Government has set up Urban Council Libraries and study

rooms in various districts. There is no doubt when books arc wisely selected. 【S4】______

The libraries and study rooms have a great educational value, and have done

much to courage the habit of reading among the people. 【S5】______

For setting up libraries, some factors should be taken to consideration. In 【S6】______

fill it books. The library building itself must be attractive in structure, desira- 【S7】______

A compact disk (CD) is used to store music. Suppose that both the two independent channels of the true stereo music with the highest frequency 22.05 kHz are sampled at the Nyquist sampling rate, then the sampling rate for each channel is f (kHz). The encoded PCM is to have an average SNR of at least 96 dB. Then, the minimum number of the uniform quantization of the sampled data should be R bits. If the Beethoven's Symphony No. 9 with 74 minutes in PCM data can be stored in CD, the minimum storage capacity of the CD should be T (MB, Megabyte). (Hint:).

A、f=44.1, R=16, T=783

B、f=22.05, R=16, T=392

C、f=44.1, R=15, T=700

D、f=44.1, R=16, T=392

Task 1

Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice.

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're beginning to fill in the blanks.

Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night? Tests with artificial stars have proved that certain night-flying birds are able to follow the stars in their long-distance flights.

A dove had 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 an artificial 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 artificial stars caused a change in the direction of his flight.

But the stars are apparently their principal means of navigation. When the stars are hidden by clouds, they apparently find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.

The reason why birds don't get lost on long flights ______.

A．have been known to scientists for years

B．have only recently been discovered

C．are known by everyone

D．will probably remain a mystery

SECTION B ENGLISH TO CHINESE

Directions: Translate the following text into Chinese.

Opera is expensive: that much is inevitable. But expensive things are not inevitably the province of the rich unless we abdicate society's power of choice. We can choose to make opera, and other expensive forms of culture, accessible to those who cannot individually pay for it. The question is: why should we? Nobody denies the imperatives of food, shelter, defence, health and education. But even in a prehistoric cave, mankind stretched out a hand not just to eat, drink or fight, but also to draw. The impulse towards culture, the desire to express and explore the world through imagination and representation, is fundamental. In Europe, this desire has found fulfilment in the masterpieces of our music, art, literature and theatre. These masterpieces are the touchstones for all our efforts; they are the touchstones for the possibilities to which human thought and imagination may aspire; they carry the most profound messages that can be sent from one human to another.
