Referring to the current hostility toward smoking,smokers frequently express anxiety that their prospects for being hired and promoted are being stunted by their habit.
此题的考点其实不是refer的用法(我做题时在此处纠结了一下),而是express时态和anxiety后面跟that or about. 看非划线部分:are being决定了句子用一般现在时、用that 【模考V第一道,仍没进入状态 不够仔细】
frequently要用一般时
有current 用现在时
frequently 用一般现在时,从后面的prospect和前面的current可以确定; 另外 anxiety 后面可以加about,但是这样只能跟短语,that的话后面跟分句
