Question

【题目】 the government has promised to improve road safety, little has been achieved so far.

A. If B. Although C. Unless D. Because

Answer 1

【答案】B

【解析】

句意：尽管政府已承诺改善道路安全，但是到目前为止收效甚微。考查连词辨析。A. If如果，引导条件状语从句；B. Although虽然、尽管，引导让步状语从句；C. Unless除非，引导条件状语从句；D. Because因为，引导原因状语从句。根据句意可知，承诺得多，实现得少，所以要用让步状语从句，表转折意义。故答案选B。
