159.
                               时态：过去完成时
                /  代词指代 /  逻辑含义

The first detailed study of magpie attacks in Australia indicates that by the time they had reached adulthood, 98 percent of men and 75 percent of women born in the country have been attacked by the birds

A. by the time they had reached adulthood, 98 percent of men and 75 percent of women born in the country
            have been attacked by the birds

B. by the time they reach adulthood, 98 percent of men and 75 percent of women, who were born in the country, had been attacked by the birds

C. by the time they reached adulthood, 98 percent of men and 75 percent of women born in the country had been attacked by the birds

在这些人成年之前，他们都被鸟攻击过。

时间上是
        过去的过去，所以
        一般过去时
        搭配
        过去完成时，时态正确。

看题目的时候，看到indicates是一般现在时，以为讲得是一个现在的事实，觉得要用一般现在时或现在完成时，当时直接就把B,C排除了，嗨，一定要认真读意思再排除不晚。

D. 98 percent of men and 75 percent of women that were born in the country were attacked by the birds by the time they reach adulthood

E. 98 percent of men and 75 percent of women who were born in the country, by the time they reached adulthood had been attacked by the birds

C对，具体分析间选项下面的解释。

另外有个疑问：

正确答案C里有问小问题，born in the country 只修饰了women，是不是应该修饰整个的“98 percent of men and 75 percent of women”才对？

这样会不会算修饰错误啊？

感觉如果是
            98 percent of men and 75 percent of women, who were born in the country,

反而不会有这个修饰的问题存在。这样看来，C也不完美啊，但只有C的时态是对的！

请大家一起来分析下这个修饰的问题吧。
