问题 PASSAGE ONE
According to the first paragraph, what’s the unexpected thing that a wheat plant did?
选项
答案It absorbed phosphorus from the desert dust covering its leaves.
解析 细节题。由题干定位至原文第一段。第一段最后两句提到，人们发现小麦做了件不可思议的事情：当它的叶子被覆盖上一层沙尘时，它竟帮自己获得了所需的磷。也就是说，小麦从覆盖其叶子的沙尘中吸收了磷，因此答案为“It absorbed phosphorus from the desert dust covering its leaves. ”。
