The following is HKCEE 1975 English Lan-
A model guage Paper II (Syllabus B). precis is given at the end.
Read the following passage carefully un- til you feel von have s general under- standing of it, and then answer the ouan ation set: at. the end.
> Thé.exact date. when people first left. the countr side to live together in cities is unknown. Some historians say this development began in western Asia: about five thousand years ago. They re- gard the formation of cities as the the ird stage in a civilizing process that took men from hunter, to peasant, to ci- tizen. They also point out that the words (city' and civilization' are clo- sely. related and suggest that only in cities can civilivation truly take root.
For ever one who accepts. this point. view there is alwas another who opp- oses it. Why do people feel so
f
differ-
ently about cities?
·Those who defend cities accept the suggestion of close relationship bet- ween cities and civilization. They poi nt out too, the, effect that citien have had on the economic conditions under which men have lived. These have been substantially improved over the centuri ea by a large number of inventione Many of these may have originated out- eide the city but they could only hayé developed within its bounds, where ade-
Cities have nuate facilities existed. had a similar effect on man's physical well-being. It too has been greatly im/ proved by the important and far-reaching discoveries of medtoine, most of which have been made in the laboratories and hospitals of the city...
And this is not all, the argument continues. Cities bring people into close contact with one another. Many of these people find that outside the city the code of every man for himself is a satisfactory one to live bye Inside the city, however, things are different. If he wishes to live in peace, a man has to learn to accept the limitations imposed on him by the law. For the same reason, he has to learn to live in harmony with
It is argued that these his neighbours. are the most important. thinge the city has taught its inhabitants.
Critics of the citys accept that. much of what its defenders say was true once but declare it is true no longer. For them the city bears a close resembl-
One ance to the popular. idea of Hell. of their many criticisms is that the de- crease in bodily disease for which the cities claim credit has been acoompanied: by an incrense in mental: disease. This has come about as a result of the count- less difficult problems created by liy- ing inja city. They point also to the alarming effect of excessive noise in cities: prolonged exposure to it can lead to violent behaviour and bring per- fectly ordinary people into conflict with the law.
Another common criticism of cities. ia that their buildings lack grace, and have no variety of light, ahape or colo- ur. They create an environment which prevents city-dwellers from developing that awareness and appreciation of beau- ty which is a mark of the civilized mang Finally, the frightening rate of expans- ion of many cities, especially in Asia. and South Americe, is giving rise to a different type of problem Indeed, in. some of these cities it ia now no longer possible to enjoy things which were once taken for granted, such as electric
Light and running water.
QUESTIONN
Summarize the arguments of those who defend cities and those who critici- ze them. Do not use more than 150 words "altogether.
Answer. Cities,
"as depicted by their defenders, are the true sites of civilization which for centuries, have housed men's econo- mic development and improvementa" upon better facilities for their, well-being: hospital, electricity, and water supply. City-dwelling has helped to bring people into a closer relatlonship. and to teach them. to be more considerate and toleran nt towards one another.
But cities have alad been criticized.as hell-like places for breeding mental illness. City-dwellers are more susce-- ptible to becoming violent and committ- ing crimes as a result of constant ex- Dosure to noises and tension. City bui- ldings are described as ugly, dull, and monotonous, contributing to the indiffe erent attitude towards art and beauty, symbols of civilization of their occup-
