A. until B. unless C. because D. although 【答案】A 【详解】句意：请待在这里直到我回来。本题考查until引导时间状语从句。until意为“直到……为止”，主句动词stay为延续性动词，符合用法，故选A。 4. I didn't know the truth ______ he told me. A. until B. unless C. when D. if 【答案】A 【详解】句意：直到他告诉我，我才知道真相。本题考查not...until...结构。know为短暂性动词，需用not...until表示“直到……才”，故选A。 5. ______ the last minute, we didn't give up. A. Until B. Till C. If D. Unless 【答案】A 【详解】句意：直到最后一分钟，我们都没有放弃。本题考查until与till的区别。句首用until，不用till，故排除B，故选A。 三、句型转换 6. We stayed in the classroom until the rain stopped.（对划线部分提问） ______ ______ you stay in the classroom? 【答案】How long did 【详解】句意：你们在教室里待了多久？本题考查对时间段提问。until引导的是时间段，用How long提问，原句为一般过去时，故填How long did。 五、although引导让步状语从句的用法 although意为“尽管、虽然”，是一个连词，引导让步状语从句，强调“前后语义对立”，主句通常为转折结果。 although引导的从句可以在前，也可以在后，从句在前，通常需要用逗号和主句隔开。 例：Although he was tired, he kept on working.（尽管他很累，他仍然继续工作。） She didn't give up although she failed many times.（尽管她失败了很多次，她并没有放弃。） 【注意】（1）although引导让步状语从句，这时主句不能再和but一起使用。 例：Although he is young, he knows a lot.（尽管他很年轻，他知道很多。）——正确 Although he is young, but he knows a lot.（×）——错误，although和but不能同时使用 （2）although和though 引导让步状语从句时通常来说可以互换，但although更正式，多用于书面语；though更口语化。 例（口语）：Although/Though he studied hard, he didn't pass the exam.（尽管他学习很努力，他没有通过考试。） Although/Though it was cold, he didn't wear a coat.（尽管天很冷，他没有穿外套。） 在固定短语：as though（好像）、even though（即使）中，不可用although替代though。 例：He looks as though he is tired.（他看起来好像很累。）——固定搭配as though，不可用as although Even though I was afraid, I still went in.（即使我很害怕，我还是走了进去。）——固定搭配even though，不可用even although 即讲即练 一、改错题 1. Although he is young, but he knows a lot. 【答案】去掉but 【详解】句意：尽管他很年轻，但他知道很多。本题考查although和but不能连用。although引导让步状语从句，主句不能再加but，故去掉but。 2. Even although I was afraid, I still went in. 【答案】将although改为though 【详解】句意：即使我很害怕，我还是走了进去。本题考查固定搭配。even though为固定搭配，意为“即使”，不可用even although，故将although改为though。 二、单项选择题 3. ______ he was tired, he kept on working. A. Unless B. Although C. Until D. As soon as 【答案】B 【详解】句意：尽管他很累，他仍然继续工作。本题考查although引导让步状语从句。although意为“尽管”，前后语义对立，符合语境，故选B。 4. She didn't give up ______ she failed many times.
