问题    Throughout history, humans have suffered from a condition that they have never been able to escape—ageing. Some researchers, however, believe we may be thinking about it in the wrong way. They say we should start treating ageing itself as a disease—one that can be prevented and treated.
   Their hopes are founded on recent discoveries that suggest biological ageing may be entirely preventable and treatable. From a biological perspective, the body ages at different rates according to genetic and environmental factors. Tiny errors build up in our DNA and our cells begin developing faults that can grow into tissue damage, which leads to ageing and ageing-related diseases.
   One of the leading figures in human life research, Aubrey De Grey, explains in an interview that their goal is to develop a set of therapies for middle-aged and older people that will leave them physically and mentally equivalent(相当的) to someone under the age of 30. "Of course, without wiping their memories, " he adds. But he doesn ’ t think that will be possible to stop ageing altogether. He sees a future where "rejuvenation technologies" can be applied to old people in order to revert their cells to what they were like when they were in their youth, buying them extra time. The idea is that someone who is treated at the age of 60 will be biologically reverted to 30. But because the therapies are not permanent fixes, their cells will end up becoming 60 years old again in another 30 years time.
The goal of De Grey’ s research is to______.
选项 A、freeze people’ s age
B、make people younger
C、stop ageing altogether
D、adjust people’ s memories
答案B
解析 细节题。根据文章第三段第一句可知，奥布里．德．格雷他们的目标是开发一套疗法，使中年人和老年人的身心相当于30岁以下的人，因此选项B(使人们更年轻)符合文章意思。根据文章第三段第二句可知，不会清除人们的记忆，因此选项D(调整人们的记忆力)错误。根据该段第三句可知，奥布里-德-格雷认为该治疗不可能完全阻止衰老，因此选项C(完全阻止人们变老)和选项A(冻结人们的年龄)均不符合文章意思。故本题选B。
