【正确答案】 C

【答案解析】[听力原文]17-20
A small girl and his mother were having a walk in the country when it suddenly began to rain very hard. They did not have their umbrellas with them, and there was nowhere to hide form the rain, so they were soon very wet, and the small girl did not feel very happy.
For a long time while they were walking home through the rain, the girl was thinking. Then at last she turned to her mother and said to her, "why does it rain, Mother? It isn't very nice, is it?"
"No, it isn't vey nice, but it's useful, "answered her mother. "It rains to make the fruit and the vegetables grow for us, and to make the grass grow for the cows and sheep."
The girl thought about this for a few seconds, and then she said, "Then, why does it rain on the road too, Mother?"

独白第一句即指出小女孩和她母亲散步的地点是在乡村：... were having a walk in the country，故本题答案是[C]。

【正确答案】 C

【答案解析】独白第一句指出开始下雨了，第二句则说她们没有带伞(They did not have their umbrellas with them)，并且没有地方躲雨(nowhere to hide from the rain)，因此很快就淋湿了。因此，[A]、[B]都是她们淋湿的原因，选[C]。

【正确答案】 B

【答案解析】独白第三段母亲的回答中直接指出：it's useful，其中的it指代的就是女孩询问时指的rain。在后面，母亲还解释了说it's useful的原因。因此本题答案是[B]。

【正确答案】 A

【答案解析】独白最后说，女孩考虑了几秒钟，然后又提出了一个问题。由这一点可以推断出，女孩对母亲的回答和解释是没有理解的，否则就不会再提出问题了，因此答案应选含否定义的[A]。
