1) People are very excited about-and proud of-the new developments of modern technology. But when they see scientists take a cell from an adult sheep and clone an exact copy of it, they feel a danger: if scientists can clone sheep and monkeys, why can't they clone humans? The concern mirrors an ambivalent feeling towards the development of modern technology.(从克隆羊引出主题,人们对现代技术的发展持有矛盾心理)

2) No one will deny that the introduction of modern technology has helped man to gain increasing control over his environment and huge benefits in his life.(主题句)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 herds.(现代技术造福于人类,用克隆技术加以说明)

3) Robots are another example. They can be programmed to perform many industrial tasks such as loading and unloading hot, heavy metals, and handling radioactive materials in nuclear power plants. Assembled with a sense of touch and the ability to see and make decisions, robots can be used to explore for minerals on the ocean floor or deep areas of mines. Obviously they free people from difficult, dangerous work.(继续用机器人来说明)

4) The growing concern over the negative effect of modern technology, however, is not without reason. If humans could be cloned, how to deal with moral and ethical problems accompanied with it? And worse, haw to prevent persons like Hitler from being cloned? The same applies to robols. Will they become smarter than the designers-humans themselves? Will they turn to evil monsters which man can't control?(现代技术带来的问题和担忧)

5) The concern is good for it calls for adequate attention to the problems of modern technology and the steps to be taken to guide the direction of its development. It is important, especially for scientist, to come up with the ways to control it instead of being controlled by it.(表明平衡看法,并提出建议。)
