【三条补充说明】

1. 这类倒装的让步状语从句可用as, though 来引导，但不能用although来引导；但是，未倒装的让步状语从句则可用though, although来引导，而不能用as来引导。也就是说，although引导让步状语从句时不能倒装，as引导让步状语从句时必须倒装，而though引导让步状语从句时可以倒装也可以不倒装。如：

虽然很晚了，但我们还是继续工作。

正：Late as [though] it was, we still went on working.

正：Though [Although] it was late, we still went on working.

误：Late although it was, we still went on working.

误：As it was late, we still went on working.

2. 上面提到的倒装结构有时也可用来表示原因，区别的办法主要看句子的内容：让步从句的内容大多数与主句在意义上相反，而原因从句则与主句之间有因果关系。比较：

Tired as he was, he sat up late studying at night.
昨晚他虽然很疲倦了，但还是学习到很晚才睡。(表让步)

Tired as he was, he went to bed early.
因为很累，所以他睡得很早。(表原因)

Young as he was, he was equal to the task.
他虽年轻，却能胜任这项工作。(表让步)

Young as he was, he was not equal to the task.
他因为年轻，所以不能胜任这项工作。(表原因)

3. 在美国英语中，人们通常用as…as引导让步状语从句。如：

Cold as it was, we went out.=As cold as it was, we went out.
尽管天气冷，我们还是出去了。

Successful as he is, he is not proud.=As successful as he is, he is not proud.
他虽成功了，但不骄傲。
