Cambridge 6 Test 1Task 1
The graph shows the differences of the water used worldwide in different parts from 1900 to 2000.
In the 20th century,the water used by agriculture was the most important part.The amount of the water increased from 500 km3 to 3000 km3 duing 100 years,especially from 1950,the amount had a rapid increase.The industrial use grew up very slowly from 1900 to 1950,but from 1950 ,it had a shape increase.At the end of the 20th century the amount of industrial use reached 1200 km3.Domestic use didn't have a clear rise during the 20th century.The amount only increased to 400 at the end of the century.
The table illustrates the discrepancy between Brazil and Democractic Republic of Congo about water consumption in 2000.In Brazil,the number of population was 176 million at that time and the number of irrigated land was 26500 km2.At the same time , numbers of population and irrigated land were 5.2 million and 100 km2.Maybe these two factors influence the Water consumption,because the number of water consumption per person in Brazil was 359 m3,but in Congo,it was only 8 m3.
In summary,the number of population is the most important factor on water use.
Task 2
As far as I know, we can see many advertisements wherever we go. Many people believe that the power of advertisements can make consumers buy something unnecessary. This opinion has its reason, it is clear to see, celebrities and popular stars are always performing in advertisements. Many people, especially young people think that if their idols think the goods are perfect they should buy them to support their idols.
I think there is another reason make people buy something without consideration. In advertisements, the factories always show the best things to consumers, they tell the consumers that their productions are with high quality and can never be broken. But in fact, many productions are not very well, even some of them can’t pass the standards that set up by our government. And people want to follow the fashion, if one of them buys it, they will buy it as soon as possible.
On the other hand, there are many different opinions against these arguments. Some people don’t believe that advertisement is a factor, which can make people buy something unnecessary. Different people have different habits. No one can be absolutely right, they will buy something they don’t need. Income is the most important element on people’s buying habit, if you don’t have enough money, you can’t afford the things you like.
In my opinion, every consumer should take care his own conditions, for example, do I have enough money or dose it necessary to me? Advertisement is a tool that attracts you. It can’t help you to make the decision whether you really need it. And it is also very important to help children and youngsters to keep good shopping habits.
