一、过去分词
过去分词作状语的用法是高考英语单项选择题的命题热点之一，也是许多考生的丢分点之一。请看近几年来的考题：
【考题探究】
例1 an important role in a new movie, Andy has a chance to become famous.
A.Offer B.Offering C.Offered D.To offer
【解析】由句子结构分析，此处应为过去分词短语作原因状语，相当于状语从句As she is offered an important role in a new movie,Andy has a chance to become famous.又因为主语Andy 与分词之间是被动关系，故选C。
例2. ______ into English, the sentence was found to have an entirely different word order.
A. Translating B. Translated C. To translate D. Having translated
【解析】由句子结构分析，此处应为过去分词短语作时间状语，相当于状语从句When it was translated into English , the sentence was found to have an entirely different word order. 又因为主语 the sentence 与分词之间是被动关系,故答案应选B。
例3._____ from the top of the tower, the south foot of the mountain is a sea of trees .（2010陕西）
A. Seen B. Seeing C. Having seen D. To see
【解析】由句子结构分析，此处应为现在分词短语作时间状语，相当于状语从句When it is seen from the top of the tower, the south foot of the mountain is a sea of trees .又因为主语the south foot与分词之间是被动关系，故选A。
例4.Though_________to see us, the professor gave us a warm welcome. （2010全国Ⅱ）
A. surprising B. as surprised C. surprised D being surprised
【解析】本题考查省略结构和非谓语动词考查。补完整为：Though he was surprised，主语一致，省略主语和系动词,即：分词在此作让步状语。故答案是C。
