上一课学了比较状语从句 —— than 比不同程度，as...as 比同级，分清比什么和谁比。
这节课进入最后一节状语从句：让步状语从句。中文说"尽管...但是..."，英语里却见不到 but。
让步状语从句
Although, No Matter & As
though、no matter、as 倒装这三种让步怎么用？
🔍 让步状语从句类型
引导词①
although
= 尽管 —— 不见 but
引导词②
no matter
= 无论 —— 退让条件
引导词③
as 倒装
= 倒装 —— 表语提前
🎯 英语让步从句见不到 but
though、although、no matter 引导让步状语从句，as 引导需倒装（Strong as he is = Though he is strong）。关键一点：英语里见不到 but，让步连词和 but 不能同时出现。
让步状语从句三步
although 表尽管
although 表"尽管"，引导让步状语从句。Although she is young, she leads the team well 里，年轻是退让，带队好是结论。注意英语里见不到 but，although 和 but 不能同时出现。 although
no matter 表无论
no matter what / where / when 表"无论什么/哪里/何时"，引导让步从句。No matter what happens, we will stay together 里，无论发生什么都要在一起，退让的是条件，结论是不分开。 no matter
as 引导需倒装
as 引导让步状语从句时，表语要倒装到句首。Strong as he is = Though he is strong，意思是尽管他很壮。学不会倒装就继续用 although，although he is strong, he is not happy 一样可以。 Strong as he is

把所有类型放在一起，一眼看清它们的区别。
本节要点：把所有类型放在一起，一眼看清它们的区别。
为什么 although 后不能加 but？
英语里见不到 but。although 已经表达了让步转折，再加 but 就重复了，二选一即可。
as 引导需倒装（Strong as he is），学不会倒装就用 although。
