【简答题】
Cities can be frightened places. The majority of the population live in noisy massive tower blocks. The sense of belonging to a community tends to appear when you live thirty floors up in a skyscraper. Strange enough, whereas in the past the inhabitants of one street all knew each other, nowadays people on the same floor in high buildings even say hello to each other. Country life, on the other hand, differs from this kind of isolated existence in that a sense of community generally keep the inhabitants of small villages together. People have the advantage of knowing that there is always someone to turn to when they need help. So country life has disadvantages too. For example, shopping becomes a major problem, and for anything slightly out of the ordinary you have to go for an expedition to the nearest large town. The country has the advantage of peace and quiet, but suffers with the disadvantage of being cut off. The city has noise and pollution which do harm to human health. But one of their main advantages is that you are at the center of things and that life doesn't come to an end even at ten at night. Some people have found a compromise among the two; they expressed their preference for the quiet life by leaving the city and moving to the country within commuting distance of the large city. (1)
