这是PERP08当中的一句正确句子:
A scrub jay can remember when it cached a particular piece of food in a particular place, researchers have discovered, and tends not to bother recovering a perishable treat stored long enough to have rotted.
我只有一个问题,为什么tend是单数形式,不可以理解成A scrub jay can remember… and (can) tend not to… 吗?
