英语中让步状语从句如何使用（1）

我们以一个题目引入今天的课程。_______ reading this book took much time, I think it's worth it.A. AlthoughB. AfterC. If onlyD. In case

那么什么是让步状语从句呢？指的是在从句中作让步状语的从句，什么是让步，本身带有妥协的味道在里。这种状语位置可防御句首或者句尾。例子：Although I love you, I can't marry you now.

让步状语从句有哪些引导词？n1. though/although两者有什么区别？Although更为正式。

例句：Although/Though it was raining, they stil play happily.Young though she is , she has accumulated much knowledge.在上述的句子中，Although一般可以和Though互换，但是反之未必可行。

n2.even though和even if这两者与其更为强烈区别：Even though 一般后面放事实情况Even if 后面一般是假设情况

例句：Even though he was late, he is the manager of the company.Even if there is a risk of failure,I still choose to try.从这两句可以分析得出：第一句，他迟到是一种客观事实。第二句，有失败的风险只是一种可能性。
