【答案解析】[范文]

When faced with the question of whether science is good or evil, someone insists that science is good in terms of the convenience and swiftness it creates, while others hold the opposing view that science is evil with regard to the large number of problems it brings about. Nevertheless, as far as I am concerned, science is just like a coin which has two sides and it is extremely unwise for us to look at one side while neglecting the other.
On the one hand, owing to modern science, the conditions of our daily life have been greatly improved. With science, we are equipped with the ability to solve the most complicated mathematical problems and put thousands of unrelated facts in order. Also, we can get in touch with somebody who is miles away at any time, and the housewives are emancipated from tedious household chores with the help of a washing machine, a dish washer, a dust cleaner and so on.
On the other hand, a lot of annoying problems come along with modern science. Radiation is affecting our health in a bad way, the noise pollution tightening our nerves, the loud conversations on mobile phones in public places invading our thoughts, and the use of pesticides and fertilizers producing unhealthy products and so on.
In a nutshell, all things are invariably divided into two and science is no exception. Thus, in the future, we should be more cautious when introducing a new instrument invented by science. [解析]
