  • 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 oneˊs 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 oneˊs free time digging, plant?ing, 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.
