问题 The original purpose of developing artificial skins, bones and tissues is to ______ .
According to Ian Pearson, ______ .
选项 A、brain will be replaceable by the end of the 21st century
B、the entire body can be replaced by 2030
C、people will be able to get a fully working replacement body part by 2020
D、people will be able to have a new face and skin by 2020
答案D
解析 细节题。根据文章结尾部分，到2020年人体96%的体重将可以被取代，只有大脑是唯一不能取代的器官。到2030年，身体部位可以被取代，而且功能完全正常。到21世纪末，人们可以换成一个全新的身体。因此只有D与此相符。
