13. Science and Human Life
科學和人類生活
With the development of science, human life has changed tremendously. People living in the 18th or 19th centuries would never imagine the advanced household appliances we are now able to enjoy. Every aspect of our lives, for instance, in the field of medicine or agriculture, has witnessed the great improvement through the application of science.
隨著科學的發展，人類的生活發生了巨大的變化。18世紀和19世紀的人無法想像我們現在所享用的家用器具。我們生活的各個方面，比如醫藥、農業，都經歷了科學所帶來的改善。
However, many people complain that science has also brought disasters to human life. Some evil scientists have used their knowledge to do some illegal things. They may use science for the creation of weapons to destroy thousands of lives in wars; they might also use their knowledge to produce drugs to make a lot of money for themselves.
然而，也有人抱怨科學帶給人類許多災難。有些邪惡的科學家利用他們的知識做一些非法之事。他們用科學知識制造武器在戰爭中摧毀成千上百的生命；他們用其知識制造毒品賺取錢財。
Generally speaking, science has provided us with many valuable things. But if used wrongly, it can also lead to harm. We should try to keep science under our control and put it to the best use for mankind.
總的說來，科學為我們帶來許多有價值的東西。但是一旦被錯誤地使用，它也能導致傷害。我們應該使之置于我們控制之下，使其為人類發揮出最大作用。
