1、学习内容：过去分词作状语过去分词在英语学习中是较难掌握的语法知识，同时又是高考中的热点之一。 过去分词兼有动词副词和形容词的特征。 过去分词作状语时，表示被动的或已完成的动作，在句中可作时间原因条件让步方式伴随状语等。掌握过去分词作状语可从以下几个方面考虑。 一理清过去分词作状语时与句子的主语的关系 1)过去分词作状语时，过去分词与主句中的主语形成逻辑上的被动关系，有时也表示动作已完成。 例如： Seen in the dark night， lights on top of tall buildings look like stars in the sky.(seen 表示被动，分词的动作与

2、谓语动词的动作同时发生) Scolded by the teacher， the girl began to cry. 被老师责怪，女孩哭了起来。(scolded 表示被动且动作已完成) 【考例 1】_ into use in April 2000， the hotline was meant for residents reporting water and heating supply breakdowns.(2005 年上海卷) A. Put B. Putting C. Having put D. Being put 【解析】选 A。主句主语 the hotline 与 put into

3、 use 逻辑上是被动关系，排除 BC；D 项表示正在进行的被动与句子意思不符。所以用过去分词 put 短语作状语。 2)有些过去分词已经形成了系表结构，因此他们作状语时与主句的主语之间是逻辑上的主动关系，但仍然用过去分词形式。例如：Lost in thought， she nearly ran into a tree. 陷入沉思，她差点撞到树上。 (lost 意为“迷失的” ，与逻辑主语连接起来相当于 Because she was lost，作原因状语 )与 lost 类似的过去分词还有 disappointed， dressed， determined， devoted， tired，

4、exhausted， prepared， seated， caught 等。 【考例 2】After his journey from abroad， Richard Jones returned home， _. A. exhausted B. exhausting C. being exhausted D. having exhausted 【解析】选 A。exhausted 意为“ 筋疲力尽的 ”，由过去分词演变成形容词作伴随状语。 二注意过去分词作状语时在句中的位置 作状语的过去分词或短语可置于句子的前后或中间，但是必须用逗号隔开以便与主句分开。 The PE teacher stoo

5、d in the middle of the playground， surrounded by a group of students. 那位体育老师站在操场中间，被一群学生围着。(过去分词作伴随状语) 【考例 1】 _ by the beauty of nature， the girl from London decided to spend another two days on the farm. (2004 年辽宁卷) A. Attracting B. Attracted C. To be attracted D. Having attracted 【解析】选 B。句子的主语 the

6、 girl 与 attract 是动宾关系或说是被动关系，所以要用过去分词短语作状语。 三掌握过去分词作状语与状语从句的变换 过去分词作状语在功能上相当于状语从句，在句中表示时间原因条件方式伴随让步等。所以经常会遇到过去分词前带有once， when， while， if， as if， even if， though， unless 等连词，我们将这种结构看成在连词与过去分词之间省略了与主句相同的主语和系动词 be。例如： Once published， this book will be popular with the students.=Once it is published， th

7、is book will be popular with the students.这本书一旦出版，它将会受到学生们的欢迎。(过去分词作时间状语。注：分词前 once 可省略) 【考例 1】_ with the size of the whole earth， the biggest ocean does not seem big at all. A. Compare B. When compared C. Comparing D. When comparing 【解析】选 B。主句中的 the biggest ocean 与 compare 形成逻辑上的被动关系，因此要用过去分词。 【考例

8、2】No matter how frequently _， the works of Beethoven still attract people all over the world. (2006 广东卷) A. performed B. performing C. to be performed D. being performed 【解析】选 A。动词 perform 与句子的主语 the works 是动宾关系，故要选过去分词 performed，实际上相当于让步状语从句 No matter how they are frequently performed， 。 四独立主格结构 如果

9、句中过去分词的逻辑主语不是句子的主语，这时必须在过去分词前加上主格的逻辑主语。这就叫作独立主格结构。例如： The town seen from the hill， we can see it more clearly.=If the town is seen from the hill， we can see it more clearly. 如果从山上看这座城市，我们能看得更清楚。 Everything taken into consideration， the party was a success. 将所有的事情考虑在内，晚会算是成功的。 (taken 的逻辑主语不是 the part

10、y， 所以添加其真正的主语everything) 【考例 1】He sat silently， _. A. eyes are closed B. his eyes closing C. eyes closed D. eyes to close 【解析】选 C。眼睛闭着表示伴随状态，如果只用过去分词closed，则前后逻辑主语不一致，所以在其前面加上 eyes 作逻辑主语，eyes closed 还可用介词 with 引导，eyes closed=with his eyes closed。1.
