please examine my essay, Schools should pay to support students' social activities or improve their meals? They should support students' social activity to allow them to become good citizens. There are many citizen who could not learned in schools during the 1960 that they deserve better treatment from government as citizens. A historical example supports my view that they must learn social activities in schools. In spite of the founding principle of the US that all men born equal, '' separate but equal'' was a legal doctrine in the US during mid of 20th century which allowed a legal racial discrimination. Under this doctrine. black citizens were treated unjustly. They are not learned that they should not be discriminated because of their skin color in the school. The majority did not object their status as second class citizens and often resorted to their subservient roles in society. The society did not changed until an man who educated about social activities in his university declared that they deserved better. This example shows that people will be suffered if they are not learned their legitimate rights. Student have to learn about social activity to be not ignorant. another example,novel 1984, supports my point of view that school should support student's social activities. the novel set in a omnipresent and omniscient nation which monitors everyone's daily life. There are people who are only allowed to learn manipulated history. if the dictator says that there will be no reduction of ration of chocolate but there is he deletes the part he lied in history books. They cannot think independently because they do not know about social activity. They hate changes because they are learned to do so. They eventually lead Winston who plans to save the masses to fail. This example demonstrates how the society becomes when they is no change and no one who want to change the society. The two examples mentioned demonstrate that student ought to learn about social activity in their school to not make the society corrupted

please check my essay ! Nowadays, neighbors depend on each other less than the people in the past. yes, neighbor do not rely on each other because they all are busy. I firmly believe that modern people cannot help but live lonely because they are too busy. They waste their time to succeed in their careers. In other word, they do not have time to talk to each other, For example, a research done by the New York Times shows that modern people are suffered from mental deceases such as nervous breakdown and depression. The study shows that modern people opt to forsake their happiness to survive in society. In sum up, they don't rely on each other because they are too busy to live their own lives . I believe people are under too much pressure. Neighbors are not allowed to depend on each others. In globalized society, they are required to do something beyond their capability because there are increasing number of people who have a degree but can have not job because the capacity of workforce has a limit . For example, a research done by CNN news shows that modern people forgo marriage because they cannot afford it.This example shows that one can not spare time to the other so neighbors do not depend on each other. In sum up, the two examples show that neighbors who are under great stress and pressure do not have enough time to depend on each other.

please examine my essay. ~! A thought provoking issue concern the way to get information. Some people believe that television have affected people's lives greater than books. Let us examine the truthfulness of this belief. for the following reasons, I personally prefer to get informations from books. because book's information are more reliable than television. First, television is not reliable resource to get information. Nowadays we are living flooding of information because of latest technology. and this also included uncertified sources. For example, I watched a beauty program, It introduced a way to cleaning face. The way was use of milk, when cleaning face, so i did, and I get terrible troubles. So, I could not help my self to meet a facial doctor. This example shows, that the television have indefiniteness informations Second, viewing television a lot can bring about addictness. It can liken a fast-food. everyone knows that fast-food can damage to health. but we can not turn to right side. And we all too familiar such cheap information and falling in so fast. This may sound old-fashioned way. but it is true. So, I am willing to participate to reading book. Please do not hesitate to mention to give your advice to me that approve my writing skills!
