City Life and Suburban Life
1． 最近几年越来越多的人迁往近郊居住
2． 城市生活和近郊生活各有特点
3． 比较起来，我喜欢的是…
(1)In recent years more and more homes are being pushed outwards as the activities of business, government and pleasure tend to be concentrated in the centers of the cities. (2)Although most people are reluctant to move to the outskirts of the cities, I feel like living in the suburbs.
(3)It is true that the city can provide much convenience and entertainment, the very reason people can’t bear to part with city life. (4)But the cost for the privilege of living in the city is also high. (5)Just think of the places where we live, full of petrol fumes and toxic gases, torn by the roar of buses and lorries day and night, and thronged ceaselessly by great crowds. (6)Besides, as the housing problem in the central city gets more serious, people have to pay high rents for very tiny flats which I would certainly disdain to live in. (7)In contrast, living near the countryside one can enjoy the clean atmosphere, the closeness to nature and the quiet, peaceful surroundings—the essentials of a healthy life. (8)Nothing can be compared, as the pace of modern life is getting quicker, with the first cock crow, the twittering of birds at dawn, and sight of the rising sun glinting on the trees and green fields. (9)Although living in the suburbs you may suffer a little discomfort brought about by the necessity of traveling miles to work every day, the situation will change soon as many highways and subways are being constructed.
(10)The new suburban life is fast becoming a predominant pattern of living in most cities; and with the development of traffic and the perfection of services, it will prove to hold great superiority over city life.
