The two graphs show the main sources of energy in the USA in the 1980s and the 1990s.
思路：
1. 采用折线模式描述
2. 注意重点数据的选取(max, min)
3. 注意分段原则：一段写上升，一段写下降，一段写保持不变。
答案：
The two graphs show that oil was the major energy source in the USA in both 1980 and 1990 and that coal, natural gas and hydroelectric power remained in much the same proportions. On the other hand, there was a dramatic rise in nuclear power, which doubled its percentage over the ten years.
Oil supplied the largest percentage of energy, although the percentage decreased from 42% in 1980 to 33% in 1990. Coal in 1990 was the second largest source of energy, increasing its proportion to 27% from 22% in the previous decade. Natural gas, the second largest source in 1980 at 26%, decreased its share very slightly to provide 25% of America’s energy ten years later. There was no change in the percentage supplied by hydroelectric power which remained at 5% of the total energy used. Nuclear power the greatest change: in 1990 it was 10%, twice that of the 1980s.
In conclusion, during the decade, the structure of energy resources remained, and the proportion of 3 aspects varied a lot, except natural gas and hydroelectric power.（180）
Information on UAE government spending in 2000. The total budget was AED 315 billion.
思路：
1. 分段原则较为灵活，可以分，也可以不分;
2. 注意数据的描述顺序为：从大到小;
3. 描述的过程中注意数据的对比：大小关系，倍数关系等;
答案：
The graph tells us about the budget of the UAE government in 2000. In general, the most important targets were social security, health, and education.
The biggest slice of the pie chart is taken up by social security including pensions, employment assistance and other benefits which made up slightly under one-third of total expenditure. Health and personal social services was the second highest budget cost. Hospital and medical services accounted for AED 53 billion, or about 15% of the budget. Education cost UAE AED 38 billion which comprises almost 12% of the whole budget. The government spent about seven percent of revenue on debt, and roughly similar amounts went towards defence (AED 22 billion) and law and order (AED 17 billion). Spending on housing, transport and industry totalled AED 37 billion. Finally, other expenditure accounted for AED 23 billion.
All in all, the bulk of UAE government spending goes on social welfare and health. However, education, defence, and law and order are also major areas of spending.（167）
3.消费模式
The pie charts show changes in U.S. spending patterns between 1966 and 1996.
思路：
1. 主要采用折线模式，重点描述数据的改变和趋势
2. 留意极值(MAX, MIN)的描述
3. 分段的原则可为：上升的一段，下降的一段，保持不变的一段。
答案：
The two pie charts above give information about the change of the spending on 6 fundamental aspects of life in U.S from 1966 to 1996.
It is noticeable that the proportion of 3 parts, namely Cars, Restaurants and Computers, increased during the period. Specifically, the expenditure on Cars rose sharply from 23% to 45%, becoming the largest in 1996. Similarly, the percentage of Restaurants also doubled. In addition, Computers, which took up the smallest proportion only at 1% in American budget of 1966, soared up by 10 times to 10% by 1996.
For the rest 3 areas, however, the 3-decade period saw an opposite downward-trend. For example, in terms of Food which played a dominant role in consumption in 1966, there was a slump from 44% to only 14%. This was followed by Patrol and Furniture, in both of which a slight drop was found. In comparison, Books cost least money in 1996, which amounted to merely 1% in total, only one-sixth of relevant spending in 1966.
In conclusion, increased amounts spent on cars, computers, and eating out were made up for by drops in expenditure on food and books.（190）
