A．that

B．which

C．how

D．what

Answer 1

D

解析试题分析：考查表语从句：句意：面对挑战，你的能力是产生影响的东西。表语从句中缺少主语，用what连接表语从句，that在表语从句中不做成分，which是“哪个”，how是“怎样”，不符合句意，选D。
考点：考查表语从句
点评：连接表语从句的连接词有：that, what, who, when, where, which, why, whether, how, whoever，whomever，whichever ，whatever等。还有如because, as if, as though等。解答这类题目，关键在于分析清楚句子结构。通过判断引导词在从句中所作的成分及意义，来选择正确的引导词。
