问题     The tree people in the Lord of the Rings—the Ents—can get around by walking. But for real trees, it’s harder to uproot. Because they’re literally rooted into the ground, they are unable to leave and go【C1】______.
    When a tree first starts growing in a certain area, it’s likely that the【C2】______envelope—:the temperature, humidity, rainfall patterns and so on—suits it. Otherwise, it would be unable to grow from a seedling. But as it【C3】______, these conditions may change and the area around it may no longer be suitable for its【C4】______.
    When that happens, many trees like walnuts, oaks and pines, rely【C5】______on so-called "scatter hoarders," such as birds, to move their seeds to new localities. Many birds like to store food for the winter, which they【C6】______retrieve.
    When the birds forget to retrieve their food—and they do sometimes—a seedling has a chance to grow. The bird Clark’s nutcracker, for example, hides up to 100,000 seeds per year, up to 30 kilometers away from the seed source, and has a very close symbiotic(共生的)relationship with several pine species, most【C7】______the whitebark pine.
    As trees outgrow their ideal【C8】______in the face of climate change, these flying ecosystem engineers could be a big help in【C9】______trees. It’s a solution for us—getting birds to do the work is cheap and effective—and it could give【C10】______oaks and pines the option to truly "make like a tree and leave. "
A)ages I)legacy
B)breathing J)notably
C)climatic K)offspring
D)elsewhere L)replanting
E)exclusively M)subsequently
F)forever N)vulnerable
G)fruitful O)withdraws
H)habitats [br] 【C5】

选项

答案 E

解析 空格位于主句的谓语动词rely——on之间,据此判断可填入副词。又根据句意“当这种情况发生的时候,很多树,比如核桃树、橡树和松树,就会——依靠所谓的‘会播种的寄宿伙伴’,比如鸟的帮助,鸟会把树种带到新的地点”可知,答案为E)exclusively“专有地,排外地,唯一地”。备选项中,forever意为“永远”,notably意为“显著地,尤其”,subsequently意为“随后,后来”,均无法体现出原文中的逻辑关系,故排除。
