A、Tiring. B、Enjoyable. C、Boring. D、Surprising. B

In general, city life is relatively convenient and comfortable. The supply of water and electricity is continuous. Whenever one wants, all he has to do is just turning on a tap or pressing a button. There is also a variety of vehicles for transportation, from buses and cars to trains and planes, which help people move about efficiently. Shopping centers are seen here and there in cities. Thanks to the amazing diversity of commodities, going shopping is often fun for city dwellers. Besides the fun of making purchases, there are also countless theatres, cinemas, art galleries and restaurants providing residents with various kinds of fascinating entertainment.
    It is true that to some extent, city life is divorced from nature. It is sometimes very exhausting because of its fast-moving pace. But on the other hand, nothing in the world is perfect; neither is city life. Viewed positively, the disadvantages should still be outweighed by its attractions. In fact, the disadvantages can be regarded as challenges to make the life in city more interesting, more exciting and more meaningful. To me, moving away from the city would mean the loss of excitement and the dynamic nature of modern life.
