大作文（环境类）
The burning of fossil fuels is universally recognized as the largest source of the emission of greenhouse gases and one of the key factors responsible for global warming. And with the development of technology and economy, more and more modern transport (such as automobiles) that run by petrol have been put into use, which inevitably leads to tremendous traffic problems and environmental pollution. Thus, some people maintain that the best approach to deal with this problem is to increase the price of gasoline. In my opinion, this measure might work to some extend, however, other resolutions should also be given equal consideration.
