单选题 When customer service representatives speak to customers over the phone, they should always speak ______.
A. hardly
B. clearly
C. respectably
D. respectively

【正确答案】 B
【答案解析】中级问题 遇到副词,要考虑它和动词的搭配。speak clearly意为“说得很明确”。hardly用在be 动词和助动词的后面、一般动词的前面,所以出现在speak的前面才对。respectably意为“可 敬地”,如果是respectfully则可以被选。(是不是该背背单词?)
