Lesson 16-2 The modern city 现代城市
The shape and dimensions of the skyscrapers depend entirely on the necessity of obtaining the maximum income per square foot of ground, and of offering to the tenants offices and apartments that please them．This caused the construction of gigantic buildings where too large masses of human beings are crowded together．Civilized men like such a way of living．While they enjoy the comfort and banal luxury of their dwelling, they do not realize that they are deprived of the necessities of life．The modern city consists of monstrous edifices and of dark, narrow streets full of petrol fumes and toxic gases, torn by the noise of the taxi-cabs, lorries and buses, and thronged ceaselessly by great crowds. Obviously, it has not been planned for the good of its inhabitants.
