答案是D没有问题，固定搭配associate with。但是expectancy是可数名词吗？前面加a？

（不好意思，基础的知识全忘记啦～

Women almost always have higher life expectancies than men. Currently, the worldwide life expectancy for all people is 63 years but for males it's 61 years and for females it's 65 years, a difference of four years. The sex difference ranges from four to six years in North America and Europe to as much as 14 years between men and women in Russia.

谢谢楼上两位！

申请进行时，你老师说的有依据吗？

查到张道真书里的解释(P41)：有些抽象名词意思可以转变，来表示比较具体的东西，这时就可以有复数形式。Expectancy本意是“期望”，是不可数抽象名词，但在这里应该是固定词组，表达具体意思“平均寿命”。
