81.        Although fruit can no longer grow once it is picked, it continues for some time to respire, taking in oxygen and giving off carbon dioxide, similar to the way human beings breathe.

(A) similar to the way human beings breathe

(B) similarly to human beings who are breathing

(C) just like the breathing of human beings

(D) as human beings when breathing（E）

(E) just as human beings do when they breathe

答案解释为：此句是两个动作的比较，所以只有E对，just as引导一个句子和主句对照。

但是我选A，请问为什么错？

一般出现SIMILY TO，错。

而且E太完美了：as 表动作的相似性；as....sb do 非常准确；

GMAT是选择相对最佳答案，没理由选A舍E阿。

多谢！
