英语翻译
After Dolly(多利羊)was born,cloning could no longer be dismissed as science fiction.The ability to create an identical twin of a lamb is but one step short of cloning humans,which many find terrifying and offensive.However the technology holds great potential for medical application.Scientists could cultivate a batch of cells and direct them to grow into whole organs or even limbs that will be genetically identical to the patient,thus eliminating the problem of rejection caused by immune reaction when they are transplanted into his body.Or they could take an organ from animals such as a pig that has been genetically altered so that it will be tolerated by the recipient.Then the lives of thousands of patients who die every year before a replacement heart,liver or kidney becomes available would be saved.

多利羊出生之后,克隆就再也不能被当成一个科学幻想而被忽视.有了制造一只和原来一模一样的羊的能力,离克隆人类就只差一步之遥了.这让很多人觉得恐惧和愤怒.但是克隆技术却在医疗应用方面有着巨大的潜力.科学家能够(用克隆技术)培养一组细胞并使他们长成与病人基因完全匹配的完整的组织甚至四肢,从而在进行移植时避免免疫反应带来的排异.或者,科学家们能从动物,例如猪的身上获得经过基因修饰的、受体能够接受的器官.这样一来,每年就能够挽救数以千计的病人的生命,使他们不必因等不到可供移植的心脏、肝脏或者肾脏而死亡.
