话题语篇导读
• After a couple has had their first child，to their disappointment they become infertile and cannot have more children.Many couples have difficulty in having children，and sometimes it is impossible for couples to have children because they are infertile.Fortunately， cloning would allow these couples to have children.This is one reason why it is difficult to decide if cloning is ethical or not.The following are some of the reasons why cloning should be allowed.
Cloning organs for organ transplants is one of the major practical reasons that cloning should be allowed.There is always a high demand for organs.Some argue for the cloning of humans to create spare body parts.Others talk of just wanting to clone an organ to replace an imperfect organ.

很多人反对克隆人，甚至有的国家禁止科学家对克隆人进行研究。

So we are unable to resist it.。
