过去分词作状语

1过去分词（短语）作状语的用法

过去分词（短语）作状语表示被动和完成的动作，即句子主语与过去分词之间存在逻辑上的被动关系。过去分词（短语）作状语，可放在句首，也可放在句后，一般用逗号同其他成分隔开，在句中可作时间、原因、条件、让步、方式或伴随状语。;Whenaskedherfutureplans,thegirlsaidthatshewantedtobeadoctor.

Disappointedbyhisbehaviour,Isaidallthistomybestfriend.

Approachedinthisway,youaresuretosolvetheproblem.

Encouragedbyhisparents,hestillhasnoconfidenceinovercomingthedifficulties.

=Whentheseproductswerefirstintroducedtothemarket,theseproductsenjoyedgreatsuccess.

=Unlesssheisspokento,shewon’tsayaword.
