When she was asked why she was late for class again, she hung her head in shame. 一、过去分词作状语 2．过去分词作原因状语 过去分词作原因状语时，可转换为由since，because或as引导的原因状语从句，这类状语多放在句子的前半部分。 Moved by the heroic deeds, the children couldn’t help crying. Because they were moved by the heroic deeds, the children couldn’t help crying. 3．过去分词作条件状语 过去分词作条件状语时，可转换为由if，once或unless等引导的条件状语从句。 Given more time, he would be able to do better. If he was given more time, he would be able to do better. 4．过去分词作让步状语 过去分词作让步状语时，相当于一个以though/although引导的让步状语从句。 Laughed at by many people, he continued his research. Though he was laughed at by many people, he continued his research. 5．过去分词作方式/伴随状语 过去分词作方式或伴随状语时，通常不能转换为状语从句，但可用并列分句代替。 The teacher stood there, surrounded by the students. 有些过去分词（短语）因来源于系表结构，作状语时不强调被动而重在描述主语的状态。这样的过去分词（短语）常见的有：lost(迷路)；seated(坐)；hidden(躲)；lost/absorbed in(沉溺于)；dressed in(穿着)；tired of(厌烦)。 Lost/Absorbed in thought, he didn’t hear the bell． 由于陷入沉思之中，他没有听到铃声。 Practice 1. Everyone was silent, ____________ (wait) to see who would be called upon to read his or her paragraph aloud. (2018•全国卷Ⅲ) 答案：waiting 解析：考查非谓语动词作状语。主语Everyone与wait为主动关系，故用现在分词作状语，故填waiting。 2. ____________ (give) a few minutes, I’ll finish the report. 答案：Given 解析：考查过去分词作条件状语。主语I与give为被动关系，故用过去分词作状语，故填Given。可转换为条件状语从句“If I am given a few minutes...”。 过去分词与句子的主语之间存在逻辑上的动宾关系，即表示被动； 现在分词与句子的主语之间存在逻辑上的主谓关系，即表示主动。 三、过去分词与现在分词作状语的区别 当过去分词的逻辑主语和句子的主语不一致时，过去分词可以有自己独立的主语，二者构成独立主格结构。 其结构：名词或代词的主格+过去分词 其功能：在句中做状语 其位置：句前、句中或句后 四、独立主格结构 The test finished (=When the test was finished), we began our holiday. 考试结束后，我们就开始放假了。 The president assassinated (=Because the president was assassinated), the whole country was in deep sorrow. 总统被暗杀了，全国上下沉浸在悲痛之中。 四、独立主格结构 1. ____________ (give) some advice by a famous musician, the young singer was not __________ (worry) about his performance any more. 2. Thousands of ____________(excite) fans welcomed the famous star. 3. The ___________(alarm) passengers rushed to help the __________(injure) woman. Given worried excited alarmed injured Practice Practice 4. ___________(move) by the peaceful music, he decided to study classical music in university. 5. __________(form) by some teenagers, the band soon became popular among students __________(interest) in hip-hop. 6.
