[单项选择]Although it might have happened anywhere, my encounter with the green banana started on a steep mountain road in the interior of Brazil. My ancient jeep was straining up through spectacular countryside when the radiator began to leak ten miles from the nearest mechanic. The over-heated engine forced me to stop at the next village, which consisted of a small store and a scattering of houses. People gathered to look. Three fine streams of hot water spouted from holes in the jacket of the radiator. "That’s easy to fix," a man said. He sent a boy running for some green bananas. He patted me on the shoulder, assuring me everything would work out. "Green bananas," he smiled. Everyone agreed.
We exchanged pleasantries while I mulled over the ramifications of the green banana. Asking questions would betray my ignorance, so I remarked on the beauty of the terrain.

[单项选择] Origin of Vegetable and Animal Life in America
When the new world was first discovered, it was found to be, like the old, full of plants and animals, and a great many tribes and nations of men lived there. Yet the plants and animals, if not the men, were all essentially different from those known in the old world. This was unexpected; it was thought to be quite remarkable.
