Ⅱ.[參考范文] 　　As far as I know, people differ greatly on cloning technique, especially on cloning human beings. Some people are in favour of its development, believing the technique is bound to benefit the medical development. On the contrary, others are afraid that it will raise a series of moral problems, thus causing damage to the social development. However, in my opinion, cloning will pay off as long as all the people obey rules and promise to use it properly. In addition, it will make more contributions to the development of society and the scientists’ efforts will not be in vain.
