In many countries of Europe 0-there has been a steady drift of people away from villages to large cities.These people,many of 1-whom have grown up in great poverty and deprivation,hope to improve their standart of 2-life and see the metropolis as the 3-solution to all their problems.In many ways,they find what they are looking for.Large cities do offer a huge number of facilities,4-....... which better education,better health care and improved housing are perhaps the most important.Large companies and factories,the vast 5-majority of which pride 6-them on looking after the interests of their employees, also open up any 7-.......... of career opportunities for those willing to work hard.Inevitably,however,there comes a time when people begin to long for the simplicity of the village or small town. Traffic problems and pollution 8 - all of which affect most large cities today,cause the most unhappiness.For people 9- of whom fresh air,unpolluted water and beautiful countryside are distant 10-at nonetheless painfull clear - memories of a previous,peaceful life in a village, the solution must at 11-least be unbearable.The pressure of overpopulation has meant that, in the last thirty or forty years, thousands 12- by thousands of new flats have been built, often with 13- no regard to architectal beauty, and the surrounding countryside has all 14- but disappeared in many cases.It is no 15-........ such an easy matter to escape the noise and turmoil of the street and find a field or a forest where the children can play in safety.

In bold is where there is a gap.This is the model that I think must be and 4/7/15 It's too difficult to me to guess what must be !
