Question

those who have weven

______I feel sorry for those who have met with the trouble，I can't really do very much to help them out．（　　）

A. Unless

B. As

C. While

D. Even

Answer 1

答案：C．
根据选项 unless除非，as 正如，因为，当…时，while当…时，尽管，然而（前后对比），even 甚至，再结合句意，然而，尽管我的确感觉很遗憾，但是我也无法做太多的事情帮助他们摆脱困境，可知此处缺少了一个引导让步状语从句的连接词，故本题中的while表示尽管=though．故C正确．
