16 D hardly……when no sooner……than 意思是一……就如果位于句子首位，用部分倒装

Answer 2

1. D,the first引导时间状语从句，for the first time只能做状语，不能引导从句，at first独立用，不能与句子直接相连，until由句意排除

2. A,before long 的意思是“不久，很快”
   . long before有两个用法：
   (1) 老早，早就(单独使用，表示比过去某时早得多的时间)

   (2) 在……的很久以前，在还没有……的很久以前

       long ago很久以前，从前；悠远；早；早已

      after long 无固定用法
