答案 On the Development of Science and Technology It is widely acknowledged that the development of science and technology makes our life more comfortable and convenient. The modern telecommunications shorten the distance between people, various transportation modes ensure smooth travel, and advanced medicine and medical treatment promote people’s health and prolong people’s lifespan. However, many severe problems arise in the process of scientific development. For one thing, environmental pollution is one of the most serious problems, some of which are caused by the advanced science and technology. For another, food safety is an increasingly important public health issue. It is reported that food-borne diseases are a widespread and ever-growing public health problem, both in developed and developing countries. In short, the development of science and technology is a double-edged sword, which brings about both positive and negative influences. First and foremost, sustainable development can be greatly promoted. In addition, we can make full use of its advantages to develop more "green" food for the public.

    第二段阐述了科技发展带来的一些问题，如环境污染严重，食品安全令人担忧。
    第三段阐明自己的观点，即科学技术是把双刃剑，只有充分利用其优点，才能有效促进可持续发展。
