问题 单项选择题

在心理层面上,中国人对自身的确认,有“身体发肤,受之父母,不敢毁伤,孝之始也”的观念,使生命受之于一个体细胞的“克隆”,可能使人们难以接受,并且失却对生命的神圣感。在技术层面上,有性繁殖是自然进化的结果,它所包含的确定性和不确定性,基本上能够保证人类适应自然的生存条件;但是,“克隆人”在进化上的不确定性,是否有利于他们适应自然而生存,人们还难以预料。对这段文字的主旨概括最确切的是()。

A.“克隆”技术面临的难关

B.中国人的生命观念与“克隆人”技术的冲突

C.有性繁殖与无性繁殖的主要区别

D.中国人难以接受“克隆人”技术的原因

答案

参考答案:B

解析: 整个文段主要从心理和技术两个层面分析人类不能接受克隆技术的原因。A项,克隆技术面临的难关虽然在文中提及,但显然并非文段主要表述的意思,且表达太过片面,所以A项不正确。C、D两项未涉及,故选B。
