【题目】His statement was so ______ that it was difficult to make out that he was trying to express.
A.vague； what was itB.ambiguous； what it was
C.explicit； what it wasD.clear； what was it
在线课程【答案】B
【解析】
考查形容词词义辨析和强调句。句意：他的陈述太模糊了，以至于我们都无法理解他到底想要表达什么。A. vague模糊的；B. ambiguous模糊不清的；C. explicit明确的；D. clear清楚的。根据it was difficult to make out（很难理解）可知， 他的陈述模糊不清，故可先排除CD，再分析句子结构可知，第二个空后的句子是宾语从句，it was+被强调的部分+that……是强调句句型，其中被强调的部分是what，又因what是连接代词，宾语从句要用陈述语气，故选B。
