Question

【题目】Many companies don’t realize ____ important the customers are, which is why they lose their customers unconsciously.

A.whatB.whetherC.howD.which

Answer 1

【答案】C

【解析】

考查宾语从句。句意：很多公司都没有意识到顾客是多么重要，这就是它们在不经意间失去顾客的原因。A. what什么；B. whether是否；C. how如何，多么；D. which哪一。分析句子结构可知，此处是用感叹句作宾语从句，important是形容词，故用how引导，故选C项。
