①Thirsty, he went into a tea house. (thirsty 是形容词,可看成是分词短语being thirsty的省略,对主语he进行补充说明)
②She sat quietly in her seat.(quietly是副词,修饰动作sat)
【注】 形容词通常不作状语,偶尔有形容词作状语,通常表示原因、方式、伴随、时间、让步等。如:
③He came in, full of fear. (表伴随,相当于When he came in, he was full of fear.)
④Ripe, the fruit tastes better. (表时间,相当于When the fruit is ripe.)
⑤Right or wrong, I will stand on your side. (表让步,相当于Whether you are right or wrong.)
(2)非谓语动词(短语),可转换成状语从句。如:
①Lost in the mountains for a week, the two students were finally saved by the local police. =句中黑体部分可补充为:After they were lost in the mountains for a week.
②It was unbelievable that the fans waited outside the gym for three hours just to have a look at the sports stars.
句中黑体部分可改为:in order that they could have a look at the sports stars
(3)状语从句。

②Roses need special care so that they can live through winter. (表目的)
