同根形容词或副词作方法状语时，有什么不同?
譬如：
Brave and strong, the activists talked to workers outside the factory.
Bravely and strongly, the activists talked to workers outside the factory.
Nervous, she tore open the letter.
Nervously, she tore open the letter.
Helpless,we watched the house being destroyed before our eyes．
Helplessly,we watched the house being destroyed before our eyes．
它们每组表达相同的意思吗？
Brave and strong, the activists talked to the workers outside the factory.
理解修饰后面谓语动词talked to，等于其副词放在句子作状语的语法功能。
The activists talked to the workers bravely and strongly outside the factory
理解等于定语从句，修饰后面句子主语the activists
The activists,who are bravel strong, talked to workers outside the factory.
Bravely and strongly, the activists talked to workers outside the factory.
解答如下
brave and strong形容词作状语，用来修饰后面句子谓语动词,有时好等于非限制性定语从句，用来修饰后面句子主语。
bravely and strongly 副词作状语，是用来修饰后面整个句子内容，作评论性状语。
Nervous, she tore open the letter.
Nervously, she tore open the letter.
使用方法同上
Helpless,we watched the house being destroyed before our eyes．
Helplessly,we watched the house being destroyed before our eyes．
使用方法同上
