参考答案
正确答案：D
句意猜测题。问题是问在文章中具体句子的具体含义。通过题干部分的信息可将解题范围定位于文章第三段倒数第四句，而正确理解这一句的关键所在是作者的表述，即：We used to think that reaching seventy years old was a remarkable achievement，．．．(我们过去常常认为人活到70：岁是极不寻常的事情)。而前半句中的remarkable和后半句中的normal构成了一对反义词，但此处normal一词不应理解为“正常的”而应理解为“不足为奇”。又因为此句中的life-span(寿命)一词与选项[D]中的life expectancy构成语义重现，故入选。
