Unit 4 Journey across a vast land 4.2 Learning About Language 过去分词作表语和状语 [观察例句] 1.The girls were amazed to see such an open country. 2.Do you feel frightened when going into the wilderness alone? 3.Seen from the top of the mountain，the scenery was really fascinating. 4.Finally，the company—headed by its new manager—started to make a profit. [归纳用法] 1.例句1中的amazed和例句2中的frightened为过去分词作表语。 2.例句3中的Seen和例句4中的headed为过去分词作状语，过去分词与其逻辑主语之间是被动关系，往往含有完成的意思。 一、过去分词作表语 1.意义 位于系动词(如be，get，become，look，feel，seem等)之后，多表示主语的状态或状况，它所体现的是形容词的特性。 She looked disappointed. 她看上去很失望。 We were encouraged at the news. 听到这个消息我们很受鼓舞。 2.过去分词作表语与被动语态的区别 过去分词作表语时，强调主语所处的状态，而动词的被动语态表示主语是动作的承受者，强调动作。 The cup is broken. 杯子碎了。(系表结构) The cup was broken by Tom. 杯子是被汤姆打碎的。(被动语态) 3.现在分词与过去分词作表语的区别 过去分词 表示人自身的感受或事物自身的状态，常译作“感到……的” 现在分词 表示事物具有的特性，常译作“令人……的” They became so worried that they stayed awake all night. 他们变得如此担心，以至于一整晚都没有睡觉。 The situation became so worrying that something should be done at once. 形势变得令人担忧，应该立刻采取措施。
