选项
A、the exposure of DNA to the public is unnecessary
B、the tiny cell in DNA is a neat little machine
C、mart knows nothing about DNA
D、man has much to learn about DNA
答案
D
解析
细节辨析题,通过理解原文即可推判得知答案。承接第4段末尾人们对DNA的再认识(But just in the last few years has become almost unbelievably complex, filled with strange parts whose functions are beyond today’s imagining),作者在第5段指出了对DNA研究的态度:继续深入地开展下去。由此确定答案为D。
