Unit 2 Why don't you talk to your parents？
核心语法：although和though引导让步状语从句
一、基本概念
although和though都表示"虽然"，引导让步状语从句，用于表达主句与从句之间的转折关系。
共同点：
都表示"尽管...但是..."
引导的从句可放在主句前或后
不能与but连用（英语中一个句子不能有两个连词）
区别：
although更正式，多用于书面语
though更口语化，且可用于句末作副词（=however）
二、基本句型结构
Although/Though + 从句, 主句
Although it was raining, we went out.（虽然下雨了，我们还是出去了。）
Though he is young, he knows a lot.（尽管他年轻，但他懂得很多。）
主句 + although/though + 从句
We went out although it was raining.
He knows a lot though he is young.
注意：
中文习惯说"虽然...但是..."，但英语中although/though不能与but连用！
Although it was cold, but we went swimming.
Although it was cold, we went swimming.
三、特殊用法
though作副词（句末，用逗号隔开）
The movie was long. It was interesting, though.（电影很长，不过很有趣。）
even though（语气更强，"即使"）
Even though she was tired, she kept working.（即使很累，她仍继续工作。）
as though（=as if，"好像"）
He talks as though he knew everything.（他说得好像什么都知道。）
四、易错点提醒
避免与but连用（重要考点！）
Though he tried hard, but he failed.
Though he tried hard, he failed.
although/though不能与however连用
Although it's expensive, however I'll buy it.
Although it's expensive, I'll buy it.
位置灵活但意义不变
Although the task was difficult, we finished it.
We finished the task although it was difficult.
五、记忆口诀
"Although/though表让步，'虽然'意思要记住；
从句主句前后放，but同现必错误；
though还能放句末，even though更强调！"

50．C
【详解】试题分析：按英语语法，although为从属连词，用以引导让步状语从句，它表明整个句子为复合句；而but为从属连词，用以引导让步状语从句，它表明整个句子为复合句；而在表示"但是"时，它是并列连词，用以连接两个简单句使之成为并列句。由于在同一句中既用了从属连词although，又用了并列连词but，使得该句一半像复合句，一半像并列句，从而导致错误。所以我们要记住although和but不能同时使用，故排除A和D，结合句意，尽管他很累，但是他还是坚持工作，排除B，故选C。
考点：连词辨析
