参考答案

正确答案：B
解析：第五段中当作者提到“learning moments”时，在同样的一句话里他说到 I had just experienced two of them atonce。Two 分别指 green banana 和 the center of the world。这两个例子都是为了说明 every place has special meanings for the people in it (第七段)和 The cultures of the world arc full of unexpected green bananas with special value and meaning (第八段)，所以文章最后一句话说 In fact, a green banana is waiting for all of us who leave our own centers of the world in order to experience other places，也就是答案B的意思。
