IX. Read the passage and answer the questions. (2.5p)

           Many people who work in London prefer to live outside it, and to go into their offices, factories or schools every day by train, car or bus, even though this means they have to get up earlier in the morning and reach home later 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 rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep well at night, and during weekends and 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 other things that are needed in a garden. Then, when the flowers and the vegetables come up, one has the reward of one who has shared the secrets of Nature.

        *True (T) or false (F)

1. ------- One disadvantage of living outside London is that houses are expensive.

2.-------- In the country people can rest from the noise and hurry of the town.

3.  ------ People in the country get fresh air.

4.  ------- People in the country usually spend their free time gardening.

        * Choose the correct answer

5.   Where do most people who work in London prefer to live?

  a. London                                         b. London’s suburbs

  c. London’s towns                            d. London’s urban areas

6.   Why do they have to get up early in the morning?

 a. Because they have to catch the early train or bus.

 b. Because they want to avoid traffic-jam.

 c. Because they live far from train or bus station.

 d. Because it often takes them a lot of time to get to their offices, factories or schools.

7. What are the advantages of living outside London?

 a. Houses are cheap                           b. There’s peace and quiet

 c. Air is fresh                                    d. All are correct
