Many people fear the effects cloning could have on our society. They imagine masses of identical people, and the production of "perfect" humans for warfare or slave labor. With such thought-provoking possibilities for the 21st century, human cloning will no doubt continue to receive widespread attention and scrutiny.
许多人担心克隆对社会带来影响。他们想象可能会出现一大群长得一模一样的人，和因战争或苦役需要而制造出的“完美”人类。我们甚至可能看到，存放在医院中作备用的无头人体。在21世纪具有如此能激发思考的种种可能性的情况下，克隆人类毫无疑问会继续受到广泛的关注及审视。
Some of the great hopes for cloning include the ability to perform transplants, whenever they are needed, using cloned organs. For example, people with lung cancer may simply have their lungs replaced with healthy ones. Scientists also look forward to the day when people in wheelchairs can walk again, and illnesses such as Alzheimer's and Parkinson's Disease can be prevented.
人们对克隆的一些伟大希望包括在需要进行移植手术时人们能使用克隆器官。例如：肺癌患者可能仅需换个健康的肺。科学家也期待着有一天长期坐轮椅的人能再站起来，老年痴呆症及帕金森氏症等疾病也都能事先预防。
