(2)When he heard the _______(move) story, he was deeply ______(move). (3)Tom was more _________(surprise) than ____________(disappoint) at this news. (4)Both he and I are ________(satisfy) with the result. ;三、过去分词作宾语补足??? 　　过去分词作宾语补足语与宾语有着动宾关系, 宾语是过去分词所表示的动作的承受者。 *He watched the TV set carried out of the room. 他看着电视机被搬出了房间。 *Last year they had the house rebuilt. 去年他们让人重建了房子。;几类能够接过去分词作宾语补足语的动词(短语) 1. 表示感觉或心理状态的动词(短语), 如see, watch, observe, find, look at, hear, listen to, feel, notice, think等。 *I heard the song sung in English. 我听到有人用英语唱这首歌。;2. 表示“致、使”意义的动词, 如have, make, get, keep, leave等。 *They managed to make themselves understood by using very simple English. 他们用了很简单的英语以使别人能听懂。 *Don’t leave tho
