1. Today, many people do not know their neighborhoods in large cities. What problems does this cause? What can be done about this?

13.Nowadays more and more children are being brought up in single parent families. What are the causes of this? What effects can be seen as a result of this?
Today, raising children in single parent families is becoming a common trend in society. Some of the main reasons are divorce because of imbalance between family and work and early marriage. The consequence of this trend is low self-esteem in children and an inability to develop to their full potential. There are two main reasons leading to divorce which are parents' workload and getting married too soon. When society is developing day by day, parents also have to work harder to be able to compete with others at work. In that way, they have a place in society and make money easier. When they spend too much time at work, they don't have time for family. Controversy is inevitable and the final result is divorce. The next reason for divorce is getting married at a young age. When parents fall in love and get married too soon, they may drop out of school and give up the diploma. Nowadays, a diploma is indispensable when applying for a job; therefore, it will be difficult for them to find a job with a good salary. Financial difficulties are also a cause of divorce when the amount of money spent for the family is not small. For example, a recent survey found that those who married early had a significantly higher divorce rate than those who married late.The consequences of divorce are the children's lack of adequate love from both mother and father. That lack will have a significant impact on children's psychology and thinking. Children raised in single parents families will not receive enough love and affection from their parents, which will affect their character and behaviour in the long run. Children will become self-esteem and afraid to communicate with people around them. In addition, they do not reach their full potential. When the family has only a mother or a father, the family's finances will be limited; therefore, investing in children will become harder. The physical and mental needs of children are also more difficult to meet when they lack a parent. For example, children raised in single parents families often do not have the opportunity to explore the world around them. In conclusion, two common reasons for divorce are the imbalance between family and work and early marriage. Being raised by single parents makes children with low levels of self-esteem and unable to reach their full potential.
14.Some young people are leaving the countryside to live in cities and towns, leaving only old people in the countryside. What problems are caused by this issue? What can be done to solve this situation?
Deciding where to live is one of the most difficult choices in life. Rising economy levels resulted in expanding urban areas and the younger population leaving the countryside. This has caused social problems ant the government should take measures to tackle this case.First and foremost, massive migration to cities and towns caused immense difficulties in relationships between the adolescents and the seniors. For instance, an elder who is not capable of using state-of-the-art technologies was forced to move with his offsprings who were looking for a lucrative position at one of the town's companies. Seniors are not able to fully take care of themselves, therefore they are either forgotten and visited only occasionally or unwillingly torn from their home.This situation can be solved with meddle of the government. As youngsters are in search of a prosperous job, various local companies, encouraged by the government, could open new factories in rural areas. This would bring benefits for both sides: workforce for the businesses and vacancies for the local dwellers. Moreover, the government ought to offer welfares for the ones willing to start their own business in the countryside. By doing this, the younger part of the population will be attracted to move to villages.To sum everything up, the countryside becomes less and less populated with young people. This causes problems for the elderly and social relations between generations. The government must take action to prevent this situation from getting adverse. Otherwise, cities will become overcrowded and most of the citizens remain unemployed
15.Many working people get little or no excercise either during the working days or in their free time, and have health problems as a result. Why do many working people not to get enough excerise? What can be done about this problem?
Heathy problems have been an outcome due to lack of exercise either on weekdays or spare time for workers. Heavy assignments and insufficient fitness facilities have been limited factors that become the main reasons for this phenomenon. What’s more, relative suggestions will also be discussed in the passage.The primary reason for this is that they face great pressure. it comes from a huge living competition which becoming more and more severe. With the increasing house price, employees who don’t try their best to make money will be knocked out. For this, they will be motivated to spend all their energy on their job rather than doing exercise. The other cause would be small quantities of playgrounds and facilities limiting their inspiration to do sports. It’s been usual that the running courses or basketball courses are full of people when they squeeze their time to be there. In this case, they are difficult to join in. To come up with this problem, I advise the government and corporations to take cooperation actions. As for the government, outputting the policies of controlling the high price of the real estate market will be a useful method to ease the burden taken by the workers. This can let them have a chance to take care of their self-fitness. Co-funding could be launched by companies and public departments which invest in adding fitness installations on large scale. In this way, residents can acquire convenient services. In conclusion, the blocks including high pressure and unabundant facilities which lead to doing exercise less can be dealt with by lowering the soaring living price and increasing the fitness devices. I believe that great progress will be made in the near future.
