在上周六1月15日场托福线下考试的时候，出现了一道环保类的独立写作题目（多走路和骑单车；废物循环利用；购买有机食品），根据学生反馈，考试整体的难度不大，之前也训练过相应的话题，虽然不怎么难，但是这里我们还是想给大家说一下试题分析及写作范文，给需要的同学们作一些备考参考。

原题：

Which one do you think is the most useful for individuals to do in their daily life to help improve the environment?

1.walking or bicycling to reduce driving a car;

2.recycling and reusing wastes instead of throwing them away;

3.buying locally grown organic foods(without pesticide);

这道题目属于利弊分析，主要围绕“个人保护环境”来展开写作。思路提示：

1、三个选项之中，我们最容易尝试和做到的选项是？为什么？
骑单车最好操作，结合生活实际

2、三个选项之中，有哪些做法相对不切实际？为什么？
废物利用可能效果不好

托福独立写作范文：环保类话题

From where I stand, walking or bicycling should be the top priority in people's daily life in terms of environmental protection.

Firstly, both walking and riding bicycles help to decrease people’s use of private cars, thus reducing harmful gas emissions. These exhaust emissions can reduce the quality of the air, particularly in big cities that are congested with cars. If people can reduce such emissions, this would mean better air quality and less air pollution. A good case in point is what Guangzhou citizens did last year. Specifically, encouraged by local government officials, people from all walks of life actively chose to use shared bikes to commute to and from work. As it turned out, such practice on a large scale proved very effective in curbing noxious fumes and the sky became much clearer as a result.

Secondly, it is true that buying organic foods is environmentally friendly because these foods may not involve extensive use of pesticides. However, there is a critical factor that goes unnoticed: affordability. By that I mean, in some regions, organic foods tend to be more expensive and inaccessible than processed foods like cans. Seeing the high price tag may already discourage a large number of consumers from purchasing organic products. Worse, limited availability makes it even more difficult for the general public to change their diet by using organic foods. Therefore, the idea of consuming organic foods may seem theoretically feasible at best but impractical in reality.
