六、范文精讲
Penicillin: An Accidental DiscoveryThat Changed the World
One of the greatest ideas that changed the world is the discovery of penicillin. It has solved the problem of treating bacterial infections.
Before penicillin, a simple cut or insect bite could lead to serious infection and even death. In 1928, Alexander Fleming was studying bacteria in his laboratory. When he came back from holiday, he noticed that mould was growing in some dishes. To his surprise, there were no bacteria around the mould. He realized that the mould was killing the bacteria. He called this substance penicillin.
Since then, penicillin has been widely used to treat infections. Thanks to this accidental discovery, millions of lives have been saved.
中文翻译改变世界最伟大想法之一是青霉素的发现，它解决了细菌感染治疗的难题。在青霉素出现之前，简单伤口、蚊虫叮咬都会引发严重感染甚至死亡。1928 年，弗莱明度假归来，发现培养皿长出霉菌，霉菌周围没有细菌。他意识到霉菌可以杀灭细菌，将该物质命名为青霉素。自此青霉素被广泛用于抗感染，这项意外发现拯救了数百万人的生命。

题目A Brilliant Idea That Solved My Problem
A Brilliant Idea That Solved My Problem
Last month, I faced a big problem. My cat always scratched my new sofa, and I didn't know what to do.
I tried many ways to stop her, but nothing worked. One day, I remembered that cats don't like the smell of oranges. Suddenly, I had a brilliant idea. I made a spray with orange peel and water. Then I sprayed it on the sofa. To my surprise, the cat never scratched the sofa again!
This experience taught me that we should think creatively when we face problems. A small idea can make a big difference.
中文翻译：上个月我遇到麻烦：家里的猫总抓新沙发，我试了很多办法都无效。忽然想到猫讨厌橘子气味，于是用橘子皮加水自制喷剂喷在沙发上。令人惊喜的是，猫再也不去抓沙发了。这件事教会我：遇到难题要创造性思考，小小的想法，也能带来巨大改变。
