5.The Positive and Negative Aspects of Skyscrapers
In recent years with fast economic growth, many skyscrapers have appeared in big cities of China.People’s attitude towards the skyscrapers varies widely.Some think of them as a sign of economic progre and a miracle of modern architecture.They also believe that building skyscrapers helps to solve the problem of the growing scarcity of land in the city, for they can obtain the maximum space per square meter of ground and meanwhile offer to the tenants offices and apartments that please them.Yet others speak of the problems skyscrapers have brought.They complain that the monstrous edifices interfere with television reception, blot out the sun and create many dark sunle streets.Besides, exceively large maes of human beings working in a single gigantic building overburden public transportation.Lightening, heating, and air conditioning strain energy supplies, to the extent that skyscrapers become lavish consumers, and wasters, of electric power.Worst of all, their reflective glaes coated with silver or gold mirror films raise the temperature of the surrounding air.With these problems and the effect the skyscraper has exerted on the environment, more and more people have begun to wonder whether skyscrapers are neceary or desirable.6.If There Were No Advertisements
Nowadays, advertisements can be found everywhere in a big city such as Shanghai.They shout at us from the television screen and radio loudspeakers, wave to us from every page of the newspaper, signal to us from the roadside billboards all day and flash meage to us in coloured lights all night.Faced with a flood of advertisements, some people wonder whether it is neceary to have such huge sums spent on advertising.They often cite in illustration of it in attractive, but false and deceptive advertisements to which many consumers fall victim.They suggest that since advertising is an entirely unproductive industry and may even harm the customers' interest, why don't we stop advertising and use the money to reduce the price of goods? It sounds like a good idea, but they fail to noticed the contribution advertising makes to our society.Because the production of a better product to compete for customers' money is the goal of advertisers, customers are thus given a chance to compare their products and get the best and cheapest one.Besides, as the advertisement can provide people with a lot of immediate and detailed information as to the availability of a certain product, or a service or a job, it makes life much more convenient.And another thing we mustn't forget: the fact that we pay so little for our daily newspapers and TV programme is due entirely to the money spent by advertisers.Advertising performs such a useful service to our society that we can’t imagine what would happen if there were no advertisements.
