雅思大作文题目：飞机限制问题
雅思大作文范文：
The argument that the flights should berestricted is invalid. Clearly, it is unconvincing tocompare the volume of pollutants an airplaneproduces with that generated by an automobile,because an airplane is shared by many passengers while an automobile is usually for one or, atthe best, several passengers.
Suppose a visitor drives 1,000 miles, burning 100 liter gasoline and emitting 10 cubicmeter carbon dioxide, this very passenger is totally responsible for such an environmentproblem. But to what extent should another passenger, who travels the same distance by air,take environment responsibility? If the airplane consumes 10,000 liter gasoline and produces1000 cubic meter carbon dioxide and if altogether 300 passengers share the flight, thentraveling by air causes less environmental damage.
Another thing must also be in the list of consideration: the time. Traveling by air savestime. The point is that even if traveling by automobiles consumes less energy and produces lesspollutants, traveling by air has a variety of reasons. For instance, a patient is transported byair from where she is injured to the hospital.
The opponents might argue that this is not the “unnecessary flights”. Nevertheless it isambiguous and vague to use such a term. How to define an “unnecessary” flight? Is therea legal or generally accepted criterion against which the feature of a flight can be clearly andcorrectly labeled as “necessary” or “unnecessary”? Nay.
Therefore, the argument mentioned in the topic is neither logically sound nor practicallysignificant.
