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.
- tend not to bother to recover a perishable treat if
- they tend not to bother recovering a perishable treat
- tending not to bother to recover a perishable treat it
- tends not to bother recovering a perishable treat
- tends not bothering to recover a perishable treat it
答案是D,后面读不懂,这个句子是什么意思啊?为什么treat后面就直接stored了? |
