1、Unit 5Music Discovering Useful Structures,过去分词作表语和状语 【情境探究】,观察上面对话, 并类比填空: (1)The teacher was _(annoy)at what the boy had done in the class. (2)The film star got off the plane, _ (surround) by enthusiastic fans.,annoyed,surrounded,【要义详析】 一、过去分词作表语 (1)过去分词作表语主要表示主语的心理感觉或所处的状态。 The well is surrounded

2、with a wall only 12 inches high. 井被只有12英寸高的井台包围着。,(2)“get + 过去分词”也能用于被动结构和系表结构, 用于被动结构时, 它强调动作的发生; 用于系表结构时, 它强调状态的变化。 *Most of the skin on his face got burnt away in the fire. 在火灾中, 他脸上的皮肤大部分烧掉了。,(3)过去分词作表语与被动语态的差异。 作表语用的过去分词表示主语的特点或所处的状态, 强调主谓关系。这种结构中的过去分词前可加quite, very, rather等修饰词。被动语态表示动作, 强调动宾关系

3、, 绝大多数被动结构中的行为执行者还可以用by短语来表示。,*The novel is well written. (系表结构) 这部小说写得很好。 *The novel is written by Lu Xun. (被动语态) 这部小说是鲁迅写的。,(4)有些过去分词作表语时, 相当于形容词, 且大部分已转化为形容词, 常见的有: delighted, disappointed, discouraged, drunk, amused, astonished, hurt, interested, crowded, tired, satisfied, pleased, surprised, wo

10、n hour, he didnt turn up at the meeting.,Compared,supported,Waited,三、现在分词与过去分词作状语的区别 1. 逻辑关系 现在分词作状语与过去分词作状语的最主要区别在于: 两者与所修饰的主句的主语的逻辑关系的区别。,(1)现在分词作状语时, 现在分词所表示的动作与句子主语之间构成逻辑上的主谓关系。 * He went out, shutting the door behind him. 他出去后随手关上了门。(he是shut这个动作的发出者, 构成逻辑上的主谓关系) *Not knowing what to do, he went

13、所表示的动作发生在谓语动作之前, 或表示“一种状态”, 与谓语动作同时发生或存在。现在分词的一般式(doing)表示的动作与谓语动作同时发生或在说话时正在进行。,*Written in a hurry, this article was not so good. 因为写得匆忙, 这篇文章不是很好。 *Reading carefully, he found something he hadnt known before. 他仔细读书时, 发现了一些从前不知道的东西。,【知识延伸】 独立主格结构 非谓语动词作状语时, 它的逻辑主语应和句子主语保持一致。但有时非谓语动词带有自己的逻辑主语, 我们称之

14、为独立主格结构, 在句中作状语。,独立主格结构的特点: 独立主格结构的逻辑主语与句子主语不同, 它独立存在; 独立主格结构中作主语的名词或代词与后面的分词或不定式是逻辑上的主谓或动宾关系; 独立主格结构一般用逗号与句子隔开。 独立主格结构的构成: 名词/代词+分词; 名词/代词+不定式; with/without+名词/代词+分词/不定式。,*The test finished(=When the test was finished), we began our holiday. 考试结束后, 我们就开始放假了。 *The president assassinated(=Because the president was assassinat
