weikai_cn在2号发贴问了0209阅读的45题。
我手头还有新东方的黄皮材料,现在又翻了一下,发现跟网上广泛流传的版本不一样,比网上常见的版本第三段多了一句话,现发贴补遗(我相信这句应该是网上版本缺失的)
第三段应为
Deer, turkey, wild pigs, and bears also feed heavily on acorns, but do not store them, and are therefore of no benefit to the trees. Flying squirrels, chipmunks, and mice are also unlikely to promote tree dispersal, as they often store seeds in tree cavities and underground burrows. Only squirrels --- whose behavior of caching (hiding) acorns below the leaf litter often promotes successful germination of acorns --- and perhaps blue jays, important long-distance dispersers, seem to help oaks spread and reproduce.
红色为缺失部分,此处缺失对46和47两题的回答造成了影响

A).they store their acorns where they cannot germinate B). they consume most of their stored acorns C). their stored acorns are located and consumed by other species D). they cannot travel the long distance required for dispersal
47. According to the passage, which of the following do squirrels and blue jays have in common?
A). They travel long distances to obtain acorns. B). They promote the reproduction of oak trees. C). They bury acorns under fallen leaves. D). They store large quantities of acorns.
