常见的作表语的V-ed有:用法1.过去分词可放在连系动词be，get，feel，remain，seem，look，become等之后作表语，表示主语所处的状态,相当于一个形容词。Tomwasastonishedtoseeasnakemovingacrossthefloor.汤姆很惊讶地看到一条蛇正爬过地板。Finallythebabyfelttiredofplayingwiththosetoys.终于婴儿厌倦了玩那些玩具。用法2.V-ed作表语，构成的系表结构与被动语态的区别:V-ed作表语，强调主语的特点或状态，相当于形容词；被动语态中，句子主语是动作的承受者，后面常跟by。Eg：Thelibraryisnowclosed．(状态)图书馆现在关闭了。Thecupwasbrokenbymylittlesisteryesterday．(动作)昨天我妹妹把杯子打碎了。有些过去分词（短语）源于系表结构，作状语时不表动作而表状态。bedressedin
