Question

【题目】I had hardly rung the bell ________ the door was opened suddenly, and my son rushed out to greet me.

A. before B. until

C. as D. since

Answer 1

【答案】A

【解析】考查固定搭配。句意：这个女孩刚一(几乎还没有)按门铃，门突然就被打开了，她的朋友冲出来迎接她。hardly...before“几乎还没有……就……”，“刚一……就……”，暗含“快”的意思。此处等于when表示“一……就”、“刚刚……就”.与hardly．scarcely连用o故选A。
