PREP2008 Q 200 呼唤大牛~~

A scrub jay can remember when it cached a particular piece of food in a particular place, researchers have discovered, and tend not to bother to recover a perishable treat if stored long enough to have rotted.

A.tend not to bother to recover a perishable treat if

B.they tend not to bother recovering a perishable treat

C.tending not to bother to recover a perishable treat it

D.tends not to bother recovering a perishable treat(D)

E.tends not bothering to recover a perishable treat it

我想请问下A为什么不对？可以看做A scrub jay can do....,and (can) do的省略呀~请教NN~~

是呀~是挺有道理的，自己看的时候对于意思总把握的不好，只在于知道他在说什么，但逻辑上对不对就常常一掠而过了~~哎~就是觉得自己对英语反应迟钝~~

是这么回事，听你一讲我就明白了，这个知识点我也知道，怎么自己就做不对呢？~~当时一看就觉得A特好，又没有代词指代问题，if...读上去也特通顺，结果，结果就悲剧了~~~~

stored long enough to have rotted作定语修饰 perishable treat 没有问题的呀，有没有if对逻辑含义都没有影响~如果要补上if，必须得把主语补出if the perishable treat was stored long enough to have rotted.
