[会发现] ①过去分词refreshed放在系动词get之后作表语，表示逻辑主语you所处的状态。 ②过去分词 discouraged放在系动词become之后作表语，表示逻辑主语great thinkers的心理感受。 ③过去分词worried放在系动词look之后作表语，表示主语He的心理感受。 ④过去分词excited放在系动词be之后作表语，表示主语we的主观心理感受。 [明规则] 过去分词(短语)作表语时，可放在系动词be， get， feel， remain， seem， look， become等之后作表语，表示主语所处的状态或心理感受，相当于形容词的作用。 [对点练] (1)用所给词的适当形式填空 ①—Are you sure you're ready for the test? —No problem. I'm well (prepare) for it. ②We got a little (sunburn), but the day had been so relaxing that we didn't mind. ③While waiting for the opportunity to get (promote), Henry did his best to perform his duty. prepared sunburned/sunburnt promoted (2)完成句子 ④Why do you always ? 你为什么总是看上去很疲劳？ ⑤I at the film I saw last night. I had expected it to be better. 我对昨晚看的电影很失望。我原以为它能更好些。 look tired was disappointed (二)过去分词(短语)作表语时与被动语态的区别 过去分词(短语)作表语时，强调主语所处的状态或特征，后面不接by短语，但可以接其他的介词；而动词的被动语态表示主语是动作的承受者，强调动作，后面常接by短语。 ①The cup is broken. 这个杯
