[讨论]大全上的一题，答案选A，我觉得是E，给些意见。

1.     
An attempt to ratify the
Equal Rights Amendment, begun almost two decades ago, has been unsuccessful
despite efforts by many important groups, including the National Organization
for Women.

(A) to ratify the
Equal Rights Amendment, begun almost two decades ago,

(B) begun almost
two decades ago, for ratifying the Equal Rights Amendment

(C) begun for
ratifying the Equal Rights Amendment almost two decades ago

(D) at ratifying
the Equal Rights Amendment, begun almost two decades ago,（A）

(E) that has begun
almost two decades ago to ratify the Equal Rights Amendment

The answer can not be E: 凡时间状语中出现ago，主句动词肯定要用一般现在时。而E中that 从句中的主句为现在完成式。so E is wrong.

时态正确是非常重要的，所以E 肯定错。

a 中begun two decades ago 的逻辑主语是attempt，意思是说the attempt was begun two decades ago, 解释得通的。
