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. [br] What will happen if someone is treated with De Grey’ s technology?

选项 A、He will stay young for a longer time.
B、He will no longer grow old.
C、He will live up to at least 60 years old.
D、He will not get ageing-related diseases.

答案 A

解析 细节题。根据文章第三段最后一句可知,由于格雷的疗法不是永久性的修复,因此,30年后,他们的细胞将会再次变成60岁时的样子,因此选项A(他的年轻会保持更长时间)符合文章意思。选项B(他不再变老)与文章意思不符。选项C(他至少会活到60岁)和选项D(他不会得与衰老相关的疾病)文中均未提及。故本题选A。
