题目内容
7．They will try their best in the Dragon Boat Racing ______ they may fail．（ ）| A． | if | B． | although | C． | unless | D． | until |
分析 他们会在龙舟竞赛中尽一切努力，尽管他们可能会失败．
解答 答案：B 考查连词的用法．答案A中if"如果"引导条件状语从句；B是引导让步状语从句，它是状语从句的一种，也就是状语从句，although引导的让步状语从句位于主句之前较多句之前较多，和though可互换，是"尽管…，但是…"；C是"除非…"引导条件状语从句，含有否定的意思；D是"直到…才…"引导时间状语从句．分析前后两个句子的关系，They will try their best in the Dragon Boat Racing 和they may fail可知，前后存在转折关系，指尽管可能失败，但他们将会在龙舟竞赛中尽全力．所以应用although引导让步状语从句，意为尽管，虽然．故选B．
点评 本题使用的是分析比较法，这种方法适用于语法、句法较为复杂的题目，从时态、语义角度进行综合分析比较来确定正确的答案．
