  • 题型描述: 阅读理解Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening.  One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one’s own.  Then, in the country one can really get away from the noise and hurry of busy working lives. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one’s free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has got the reward together with those who have shared the secret of Nature.  Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight’s (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night.  1、 The underlined phrase get away from in the 3rd paragraph refers to _ _ _ _ _ _ _ _ .  A. do away with B. escape from C. prevent from D. deal with  2、 People who think happiness lies in the town would feel that _ _ _ _ _ _ _ if they had to live  outside London.   A. their life was invaluable  B. their life was meaningless C. they were not worthy of their happy life  D. they didn’t deserve a happy life 3、 When the garden is in blossom, it means that one _ _ _ _ _ _ _ _ has been rewarded. A. having a garden of his own B. living in the country C. having been digging, planting and watering  D. having spent time working in the garden  4、 With the same money _ _ _ _ _ _ _ _ , one can buy a little house with a garden in the country.  A. getting a small flat with a garden B. having a small flat with a garden  C. buying a small flat without a garden  D. renting a small flat without a garden 5、 Which of the following statements is NOT true? _ _ _ _ _ _ _ _ _ A. People who love Nature prefer to live outside the city.   B. Some people enjoying city life prefer to work and live inside London.   C. People who work in London prefer to live in the country.   D.
