GWD 第19套，做完后发现几道语法题 的答案很奇怪，比如第一题，

Although women’s wages are improving, Department of Labor statistics show that the ratio of their earnings with that of men have been roughly static since 1960.

A.    with that of men have been

B.    to that of men are

C.    to those of men have been

D.    with those of men is

E.     to those of men has been

答案是E，请问为什么选E? 我觉得不应该用those

是不是ratio ...to 的搭配好一点呢 ？ 而且since这样的logo应该暗示会用完成时吧。。。

我也菜鸟 随便说说 nn们别喷

哦，对，要用has been

切尔西

earnings 对应 those, ratio of ...to...

还原是show that the ratio of their earnings  to the earnings of men, 从句主语是ratio，用单数，后面有明显完成时标志since。E很完美
