Sample 2 Writing 1 Almost everyday we see something on TV about the new exciting developments in science and technology. The latest one, perhaps, is cloning. News has come from England that researchers have succeeded in creating a lamb from a cell in an adult ewe, a young lamb which is in essence her mother’s identical twin. Although people cheer the embryonic cloning as a breakthrough in reproductive technology, they also feel a danger: if scientists can clone sheep, why they cannot clone people? As I see, the mixed feeling is a mirror of their concern over the development of technology. No one will deny that the introduction of modern technology has improved the structure of society, and helped man to gain increasing control over his environment. The technology of cloning, for example, opens up many exciting possibilities, from propagating endangered animal species to producing replacement organs for transplant patients. Agriculture stands to benefit as well: dairy farmers could clone their champion cows, making it possible to produce more milk from smaller herds. Another example of the benefit man gains from technology is the computer. The development of computer technology leads to the creation of robots which provide man with much help in many aspects. For instance, with the aid of robots, the components of a car can be assembled more quickly and more accurately than that done by human hands, thus lower cost of cars and better quality too. The growing concern over the effect of technology, however, I believe, is not without reason. It is clear that many major problems we are confronted with today are either a direct or indirect consequence of technological development. For example, severe air pollution brought on by the wide application of modern technology in factories has posed a threat to human survival. It not only causes much acid rain but also the loss of the ozone layer in the atmosphere, which will expose human beings directly under the solar ultra-violet rays. To the well-known example of air pollution, two more may be added: the depletion of energy resources and the military space race. From my point of view, since seeking for better living environment is one of the chief desires of human beings, it is necessary that steps should be called for to guide the direction of technological development and to improve our protection against harmful uses of technology. Among other things, the political system must exert more effective control over technology. better means must be found to anticipate its consequences. and more reliable information about technological developments must be available to people at large, so that a human clone won’t emerge in the future.

Writing 2 Whenever we mention modern technology, people’s opinions always vary differently. Technology refers to the skills, knowledge and technique that human beings use in heir daily life and in production. They have both advantages and disadvantages. It solves many human problems and makes life much better. For example with computer technology, we can do work more efficiently and more quickly than before. With cloning technology we can prevent many animals and plants from being extinct. With modern drugs and advanced surgical techniques, we have cured many diseases and prolonged life. With modern jet planes, traveling to different parts of the world takes only few hours or days instead of weeks and months. We owe all this to modern technology. But technology has created a number of new problems. The computer makes life easy, but deprives people of the chance to contact with each other. The airplane makes traveling easy, but exposes people to accidents which have become so numerous and claim many lives daily. The machine makes work easy, but they give out many poisonous gases which expose us to lung diseases, and even cancers. In conclusion, I think that although advances in technology may seem desirable and favorable, there are also a lot of problems which it introduces into our ways of life.
