题目：
Which of the following statements is tree about his friend a. Writing exhausts his friend. b. His friend collects a lot of things to write. c. His friend always has enough material to write on. d. His friend is doing research to write a paper.
答案：
参考答案：C
解析：[听力原文]His friend never runs out of things to write.
[分析]： 固定搭配。 根据原文“His friend never runs out of things to write．”，译文为：他朋友的写作素材永远不会枯竭(用完)。关键在于理解固定搭配run out of，run out of的意思是：用完，耗光。c选项是对原文的正确解释。a选项“Writing exhausts his friend．(写作耗尽了他朋友的灵感。)”正是对原文的否定。exhaust意思是：用完，耗尽。
