【正确答案】
Modern science and technology render people many advantages. For example, modern telecommunication shortens the distance between people and makes communication much easier. The Internet is widely used now not only for collection of abundant information but also for correspondence. For another example, modern transportation, such as airplanes and high-speed trains, makes our journey smooth and fast. With the help of modern transportation, the journey to outer space and other planets is not a dream any more. In one word, the development of science and technology makes our life more comfortable and convenient.
However, the process of scientific development also arouses many severe problems to our human beings. Firstly, the Internet, though widely used in modern communication, is easy to be destroyed by computer viruses. In addition, outer space exploration has produced much waste in the space. Last but not least, industrialization is making natural resources become scarce. Consequently, science has brought many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources.
In my opinion it is a double-edged sword. On the one hand, not only need we acquire knowledge and skill of science and technology, but also we need apply them into the practice which may bring benefits to our human beings. On the other hand, we must be confronted with these problems and try every means to seek prompt and feasible solutions to these problems. The development of science and technology brings about both positive and negative effects to us. We must eliminate the negative effects to the least extent.
