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 botherrecovering a perishable treat (D) E. tends not bothering to recover a perishable treat it
答案 D 有没有NN可以帮忙解答一下正确选项 a perishable treat stored long enough to have rotted 中标亮部分是修饰treat省略了that吗,如果是的话 to have rotted是做什么成分呢?状语吗?
