问题 On average women lived longer than men 100 years ago.
People now enjoy longer lives for unknown reasons.

选项 A、Right
B、Wrong
C、Not mentioned

答案B

解析 直接借助常识判断该句说法错误,因此该句答案很可能是B。同样题干中有两个较明确的细节信息,因此考虑把题干内容分成2层:People now enjoy longer lives+for unknown reasons,注意观察文章中有没有提到关于原因的句子,这样发现答案相关句:Do you know that we live a lot longer now than the people who were born before us?(该句内容显示信息1正确)One of them main reasons for people living longer is that we know how to look after ourselves better.(该句内容显示信息2错误:该句直接提到了人们寿命增加的原因,显然与题干中所说的“由于未知的原因”相矛盾)
