Writing task 1: The various sources of electricity in the U.S.A


The two pie charts represent the various sources of electricity in the USA.
Describe the information by selecting the main infoemation and make comparisons where relevant. (150 words)












The pie charts indicate the variety of electrical origins in the USA in 1970 and 1984 by percentages. There are many ways to produce electricity which are by coal, by oil, by hydro – power and by nuclear. As can be seen, the electricity which is manufactured by coal had the biggest proportion in both 1970 and 1984, with 46% and 55.5%

According to the pie charts, in 1970, besides the biggest percentages of electricity made by coal, with 46%, most of electricity was produced by natural gas, hydro – power and oil. It was just 12.1 percent of electricity made by oil, which was about a half of the percentages of the electricity produced by natural gas, with 24.3%. There was very small amount of electricity made by nuclear, just 1.4%

It was clear that in 1984, electricity made by coal was still the most used electricity in USA with 55.5%. However, there were many changes in other origins of electricity. The percentage of electricity produced by natural gas was just as a half of the ones in 1970, with 12.3%. Electricity manufactured by hydro – power and oil were also lower than they were in 1970 with 13.7% of electricity made by hydro – power and just only 7% of electricity produced by oil. But the electricity made by nuclear was increased sharply, just from 1.4% in 1970 to 13, 5% in 1984.

To sum up, the electricity made by coal still had the biggest proportion. Other origins of electricity which was hydro – power, oil and natural gas was decreased gradually while the proportion of electricity produced by nuclear was rise sharply.

Essay: Teaching children how to become good members of society

Topic: Some people think that parents should teach children how to be good members of society. Others, however, believe that school is the place to learn this.
Discuss both these views and give your own opinion 
It is unarguable that nowadays teaching children how to have a good manner is becoming more and more difficult. There are many debates globally that parents should take responsibility to make their children become good members of society. However, other people think that this duty has to be taken by schools. From my point of view, it is a responsibility of both schools and parents.

It is clear that parents have a big effect on their children. If parents are bad, their children will have a bad behavior. So they have to live in good way if they want their children to grow well. Another principal reason is that parents are the only people who the children can share their secrets and help them get over their troubles. Recent researches show that the more parents listen to their children the better they are in future.

 Furthermore, beside parents, children are also affected by many other things such as society, friends and especially schools. If children go to school everyday and they are only taught knowledge about maths, literature, history etc they will be bored quickly. They want to prove themselves in many ways so if schools teach them the right ways, they will follow them. Another point I want to add is that friends also have a large impact on the children. Maybe friends have an effect as large as parents do so a good school will have a right method to choose students who are good enough.

In general, I think that children are affected by a plenty of things and teaching them how to become good members of society is always very difficult and takes a long time. However, I believe that with the patience and advice from both parents and school, children will become good members of society in future.
