D、major depression is suffered by the age of seventy-five by only one percent of Americans born before 1905, and by age twenty-four by the six percent born since 1955
E、Americans born before 1905 suffer major depression by the age of seventy-five only one percent of the time, but six percent of those born since 1955 did so by age twenty-four
答案
A
解析
由两个by时间短语,就可确定其对应修饰的动词均应用过去完成时,前面已提到,含by时间短语的句子要么用过去完成时,要么用一般将来时,此时,两个时间短语均为说话之前的时间,因而就只能用过去完成时。由此判定,仅A符合此要求,而B、C、D、E中的时态都是极其混乱的。
