Составить план к тексту. Sometimes you may think that city life is better than village. However there are many advantages and disadvantages of living either in a city or in a village.
There are a lot of facilities for people in the city and they have more opportunities for making money. Children can get a good education. Living in a big city with a large population, you get used to making contacts and in this way you become more socialized. There are large shops, banks, offices, cinemas, hotels, clubs, hospitals etc in and around a city. People have better transport facilities. There are the facilities or electricity, highways, communication, telecommunication, and plumbing. So people can lead a comfortable and enjoyable life.
But there are some disadvantages too. The cost of living is very high in the city. Most goods and food products are expensive. There is no fresh air and pure water. The pace of life is high. The environment is polluted with dust, smoke, garbage and dioxide gases from factories. The streets are dusty and unclean. So it is hard to lead a healthy life. Many criminal activities often take place in the city. The city is always busy and noisy. There are a lot of vehicles and people on the roads.
There are also many advantages in village life. Generally, people there live in harmony and peace. They have more friends in the community since it is small. The village people always try to protect their traditional habits and culture. The village has clean air, less noise, pollution and rush, and the environment is very beautiful. The village has few vehicles, so roads are less dangerous for driving or cycling. People can easily get fresh vegetables, fruits, meat and milk.
Village life also has its bad points. Some people are not well-education. Villagers’ children go to the village school. They have difficulty in keeping up with new developments in their field or profession. They have to face many difficulties in their everyday lives, like travelling problems, entertainment and culture. They have to go to the city to supply some of their needs.
