【让步状语从句是什么】让步状语从句是英语中一种重要的从句类型,用于表达“尽管……”、“虽然……”的意思。它用来引出与主句相反或不一致的情况,表示让步关系。让步状语从句在句子中充当状语,说明主句动作发生时的背景或条件。
一、让步状语从句的基本概念
让步状语从句的作用是说明主句内容虽然存在某种情况,但并不影响主句所表达的意思。这种从句通常由特定的连词引导,如 although, though, even if, even though, no matter what, as 等。
例如:
- Although it was raining, we went out.
(虽然下雨了,我们还是出去了。)
- Even though he is rich, he lives simply.
(即使他很富有,他生活也很简朴。)
二、常见让步状语从句引导词及用法对比
引导词 | 含义 | 用法说明 | 例句 |
although | 虽然 | 引导让步状语从句,语气较正式 | Although he is tired, he continues working. |
though | 虽然 | 与although基本相同,语气更口语化 | He is late, though he promised to come on time. |
even if | 即使 | 表示假设性让步,强调可能性 | Even if it rains, we will go. |
even though | 即使 | 强调事实性的让步,比even if更常用 | Even though she was tired, she stayed up. |

as | 尽管 | 用于倒装结构,放在句首 | Child as he is, he knows a lot. |
三、让步状语从句的使用注意事项
1. 不能与but同时使用:在英语中,让步状语从句不能和but连用,因为两者都表示转折,会造成重复。
- ❌ Although he is rich, but he is not happy.
- ✅ Although he is rich, he is not happy.
2. as 的特殊用法:当使用as引导让步状语从句时,通常要将表语或副词提前到句首,形成倒装结构。
- 正常语序:He is a child, and he knows a lot.
- 倒装语序:Child as he is, he knows a lot.
3. no matter 的用法:no matter + 疑问词(what, who, when, where, how, which)可以引导让步状语从句,表示“无论……”。
