答案 Science and Human Life In modem times science to human beings is like food to our bodies. It is science that frees us from the bondage of Nature. More than fifty years ago, aero planes, cars, steamers were in the course of development. Man’s life was not as convenient as today. So science is our benefactor. But when it is wrongly used, its destructive power is uncontrollable and terrible. For example, atomic energy can help us to change deserts into seas, to remove mountains, and so on, yet it can also destroy thousands and thousands of lives in a split second. We must make science serve us for our benefit. People are trying hard to make better use of science. One scientist said, "In the past, man studied science because he wanted to understand Nature. But to day, to study science is to master Nature." What he said is really true. Today more and more achievements have been obtained, in science, this makes it possible for us to realize our dreams.
解析     这是一篇典型的段首句作文。作者在第一段运用举例说明法对所给的主题句“Science to human beings is like food to our bodies.”进行论证。在第二段作者用原子能(atomic energy)的例子说明：如果使用不当，科学会给人类带来难以控制的可怕的灾难。作者在第三段引用一位科学家的话“过去人类是因为要认识自然而研究科学，而现在研究科学是为了掌握自然”来论证，人类应努力更好地利用科学，实现自己的梦想。
    全文长短句结合，读起来很有节奏感。作者使用了举例法和列举法，论证充分有力，过渡自然。
