求问一道语法题 来自prep08

415lethe

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 recover bering a perishable treat
C. tending not to bother to recover a perishable treat it
D. tends not to bother recovering a perishable treat
E. tends not bothering to recover a perishable treat it










正确答案选D  prep08上的解释整句话的结构是A scrub jay can remember ..., …, and tends not to bother recovering a treat…
有个疑问是 ，and后面的动词不和前面的情态动词can平行 而应该用tend嘛？

解题思路：
主语是A jay, 所以谓语应该是单数，A错了（tend）。B也错了（they不能代指a jay). 此外tend to  ...

对我的意思是tend为什么不可以和remember不平 不用tends  如果给了一个tend开头的选项的话可以正确吗？
