Question

【题目】Too much fast food is bad for us. But I only have it ________.

A.all the timeB.from now on

C.once in a whileD.at the moment

Answer 1

【答案】C

【解析】

句意：吃太多快餐对我们身体有害。但是我只是偶尔吃一次。

考查副词短语。all the time一直；from now on从现在起；once in a while偶尔；at the moment此刻，现在。根据but可知，前后文应为转折关系。上文是“吃太多快餐对身体不好”，所以下文应是“我只偶尔吃一次”，故此处应为once in a while偶尔。故选C。
