（作文开篇直接点出话题，给出了信息，完成了说明文开头的主要任务。）

②The first chart describes the situation of energy consumption in China. It indicates that coal is the dominant energy consumption, accounting for 70 percent of the total energy consumption. The other two major fossil fuels, oil and natural gas, take up 18 percent and 4 percent respectively. These three kinds of fossil fuels, in aggregate, already account for over 90percent of all the consuming energies, indicating that fossil fuels play a vital role in China’s energy consumption in the recent years. The remaining 8percent of energy consumption includes nuclear power and some kinds of renewable sources like hydroelectric and so on. Among them, nuclear power accounts for 1 percent. As for the renewable sources, hydroelectric takes up 5percent and another 1 percent taken up by other renewable sources.

④The analysis of the features of the two charts makes people perceive certain connections and comparisons between them. As for the connections, Just as mentioned earlier, consumption of the fossil fuels accounts for a great deal in both China and the United States. However, the two charts, if compared carefully, also show that the structure of primary energy consumption varies in the two countries.

（这一段简要介绍了题目的第二项任务，寻求两个图表之间的对比。在下两段进行具体分析。）

⑤Firstly, among the three major fossil fuels, coal is the dominant energy in China to a degree up to 70 percent, while in the United States, the number is much smaller-- only 22 percent, but oil and natural gas take up larger proportion.
