[单选题]请阅读短文,完成此题。
I am one of the many city people who are always saying that given the choice we should preterto live in the country away from the dirt and noise of a large city. I have managed to convincemyself that if it weren't for my job I would immediately head out for the open spaces and go backto nature in some sleepy village buried in the country. But how realistic is the dream?
Cities can be frightening places. The majority of the population live in massive tower blocks,noisy, dirty and impersonal. The sense of belonging to a community tends to disappear when youlive fifteen floors up. All you can see from your windows is sky, or other blocks of flats. Childrenbecome aggressive and nervous--cooped up at home all day, with nowhere to play; their mothefeel islated from the rest of the world. Strangely enough, whereas in the past the inhabitants of one street all knew each other, nowadays people on the same floor in tower blocks don't even say hello to each other.
Country life, on the other hand, differs i~om this kind of isolated existence in that a sense of community generally binds the inhabitants of small villages together. People have the advantage of knowing that there is always someone to turn to when they need help. But country life has disadvantages too. While it is true that you may be among fiSends in a village, it is also true that you are from the exciting and important events that take place in cities. There's little possibility of going to a new show or the latest movie. Shopping becomes a major problem, anti for anythingslightly out of the ordinary you have to go on an expedition to the nearest large town. The city dweller who leaves for the country, is often oppressed by a sense of unbearable stillness and quiet.
What, then, is the answer? The country has the advantage of peace and quiet, but suffers ti'om the disadvantage of being cut off; the city breeds a feeling of isolation, and constant noise batters the senses. But one of its tnain advantages is that you are at the centre of things; and that life doesn't come to an end at half past nine at night. Some people have found(or rather bought) a compromise between the two: they have expressed their preference for the"quiet life" by leaving the suburbs and moving to villages within commuting distance of large cities. They generally have about as much sensitivity as the plastic flowers they leave behind--they are polluted with strange ideas about change and improvement which they force on to the unwilling original inhabitants of the villages.
Which of the following is not the disadvantage of country life?

A.It is inconvenient to buy something.
B.Villagers can't enjoy the exciting events.
C.Villagers have little opportunity to see a film.
D.There are many friends around each villager.
[填空题]
So at least the historical evidence seems to suggest. When I was graduating from college, my 1 also found the world in a mess. The economic machinery had 2 down almost everywhere: In this country 3 a quarter of the population was out of work. A major war seemed all too 4 . As a college newspaper editor at that time, I protested 5 this just as vehemently as student 6 are protesting today. But today she passed the baker’s by, climbed the 7 , went into the little dark room—her room like a cupboard—and sat down on the red eiderdown. She sat 8 for a long time. The box 9 the fur came out of was 10 the bed. She unclasped the necklet quickly; quickly, 11 looking, laid it inside. But when she put the 12 on she thought she heard something crying. The Watts-as-a-way-station mentality has a firm hold on 13 those who remain and those who leave. Such as 14
