【题目】A Cambodian boy has become famous on the Internet. When ________ about how he picked up so many languages, he said he learned them from other tourists.
A. asked B. asking
C. being asked D. having asked
在线课程【答案】A
【解析】
考查非谓语动词。句意：一个柬埔寨男孩在互联网上出名了。当被问及他是如何学会这么多语言时，他说他是从其他游客那里学来的。ask的逻辑主语是he，它们之间是被动关系，用过去分词作时间状语，故选A。
