尽管被人嘲笑尽管这次被打败过去分词短语作状语时，前面有时可以加上when,if,while,though,asif等连词，这种结构可以看作是一种省略的状语从句（省略部分多为“主语+be的多种形式”）。需要注意的是，省略的主语必须和主句的主语相同，如：If/When(wateris)heated,waterchangesintosteam.Evenif(Iam)invited,Iwon’tgo.Wewillnotattackunless(weare)attacked.Thegirlisveryshy,andneverspeaksuntil(thegirlis)spokento.Part3过去分词作表语Whenpeoplearedeterminedtheycanovercomeanything.——南非前总统曼德拉人心齐，泰山移。——中国谚语，出自《古今贤文》要点一：

表状态：addicted,broken,gone,lost,seated,absorbed,dressed,separated,engaged…表主观心理感受：excited,moved,puzzled,disappointed,surprised,frightened…过去分词作表语表示主语所处状态或主观心理感受，相当于形容词的作用。此类常见词有：TheyoungNBAbasketballstarismarried.Thewindowofmyroomisbroken.Don'tbesodisappointed.Weareexcitedtohearthegoodnews.Wearealwayspleasedtobeabletohelp.状态主观心理感受要点二：

过去分词作表语时，与谓语动词构成系表结构，该结构易与被动结构混淆：一般情况下，作表语用的过去分词前可加quite，very，rather等修饰语。而被动语态强调动宾关系，多可后接by短语。Theboywasabsorbedinthebook.男孩沉浸在书中。（系表结构）Theboywassavedbyapoliceman.男孩是被一名警察救的。（被动语态）要点三：个别情况下，主语是人也可表示“令人/使别人感到...”；主语是物也可表示“感到/觉得...”。Heisterrifying.
