2020年7月大學英語六級作文范文：中國天然氣含量

Natural Gas Output in China

As can be seen from the above graph, there have been a steady increase in the output of natural gas since 1999. In 1999, there was only 15.5 billion cubic meters of natural gas produced in China. After that, almost every year witnessed a steady increase by 0.5 billion cubic meters. By 2013, the output had increased to 17.5 billion cubic meters, an increase by about 13% over that of 1999.

There are many factors leading to this sharp increase in its output. To name only a few, the first one is the convenience and cleanness in itself which meet the demands of housewives for daily use and thus stimulate its output increase. The second one is that there has been an increasingly great demand for fuel resources from industries and factories because of the rapid economic growth in China.

In conclusion, we can safely predict the output will continue to increase in the foreseeable future because of the greater demands for it.
