非谓语动词:过去分词 过去分词(短语)作状语 过去分词表示完成或被动,作状语时,表示动作发生的背景或者情况,在意义上相当于一个状语从句,其省略的主语(逻辑主语)就是主句的主语,且与主语之间存在被动关系。过去分词作状语可以表示时间、条件、方式、原因、让步等。过去分词的否定式就是将not放在其前面。 一、过去分词作状语时的具体用法: 1)过去分词作时间状语时,相当于一个时间状语从句。有时过去分词前可加连词when或 while来强调时间概念、 例:1、Asked (When he was asked) what had happened, his face turned red、 当她被问及发生了什么的时候,她的脸红了。 2、When heated (When it is heated), water changes into steam、当加热时,水变成水蒸气。 3、Told that his mother was ill(When he was told that his mother was illl), Li Lei hurried home quickly、李蕾得知母亲生病了时,马上赶回了家。 4、Seen from the moon(When it is seen from the moon) , the earth looks green、从月亮上 瞧时,地球就是绿色。 2)过去分词作原因状语时,相当于一个由as, since, because等词引导的原因状语从句。例:1、Deeply (Because they were) moved by the movie, the children began to cry、由于被电影深深地感动,孩子们哭了起来。 2、Frightened (Because she was frightened) by the horror movie, the girl didn't dare to sleep alone、因为被惊悚电影吓坏了,这个女孩不敢单独睡觉。 3、Caught in a heavy rain (Because he was caught in a、、、), he was all wet、 4、Satisfied with what he did (Because the teacher was satisfied with、、、), the teacher praised him in class、由于老师对她所做的事情很满意,于就是在班上表扬了她。 3)过去分词作条件状语时,通常放在句子的前面,相当于if, unless等引导的条件状语从句。例:1、Compared with you (If we are compared) , we still have a long way to go、
分词作状语用法小结 在高中英语语法中，非谓语动词的学习是一个重点，同是也是一个难点。而其中的分词的用法更是重中之重了，掌握了分词的运用对于我们突破阅读理解中的长句子，以及写作水平的提高都会很有帮助，下面就分词作状语的用法作以下总结。 分词在语法功能上相当于形容词和副词，分词或分词短语作状语时，可以表时间，原因，结果，条件，让步，行为方式，伴随状况等。表示时间关系的分词短语有时可由连词while 或when引出。（一般情况下过去分词不作结果状 的动作同时发生或两者之间时间间隔并不长。例如： I stayed up very late yesterday, preparing my speech on greenhouse. Hearing the good news, the students were wild with joy. He sends me an e-mail, hoping to get further information. Being written in haste, the composition is full of mistakes. 从所给的例句是我们可以看出，现在分词的一般主动式所表达的是：分词与句中主语构成逻辑上的主谓关系，也就是我们常说的主动关系，而其一般被动式却表达的是：分词与句中主语构成逻辑上的动宾关系，也就是我们常说的被动关系。并且现在分词的一般被动式一般作原因状语位于句首，请看以下例句：Being a student, he was interested in books. Being very small, computers are widely used. Being tired, I can’t go on walking. 2. 现在分词的完成式：表示分词的动作在句中谓语动词所表示的动作或 状态之前就已发生。例如： Having done the work, he went home. Having worked in the country for three years, he knew how to grow vegetables Having been bitten by a snake, she was frightened at it. Having been told many times, he still repeated the same mistake. Having been deserted by his guide, he could not find his way through the jungle. 从以上例句中我们可以看出，现在分词的完成主动式表达的是：分词与句中主语构成逻辑上的主谓关系，先于谓语动词发生。而其完成被动式却表示分词与句中主语构成逻辑上的动宾关系，也是先于谓语动词发生。 3．过去分词：分词与句中主语构成逻辑上的动宾关系，不强调一定要先于谓语动词之前就已发生。例如： Heated, this kind of wood gives off much smoke. The teacher entered the lab, followed by the students. Given a chance, I can surprise the world. Founded in 1936, Harward is one of the most famous universities in the United States.
分词作状语需要注意的问题: 一. 表示伴随，行为方式 He ran to me, holding a letter in his hand. Accompanied by his friends, he went to the railway station. He scratched his head, wondering how to solve the problem. She came back running. 二．表示时间，相当于when, after 引导的时间状语从句 Seeing this, we became worried. (When we saw this, we became worried.) Taking a key out of his pocket, he opened the door. (After he took a key out of his pocket, he opened the door.) Heated to 100 degree, water boils. (When water is heated to 100 degree, it boils.) 三．表示原因，背景，状况，相当于because引导的状语从句Not having enough hands, we turned to them for help. Born in a poor family, he had only two years of schooling. Absorbed in his work, he neglected food and sleep. Not having received a reply, he decided to write again. Having finished the experiment, he left the lab. Having been giving such a good chance, hw could she let it slip away. 四．表示条件和假设，相当于if引导的状语从句 Taken in time, the medicine will be quite effective. 五．表示结果 He fell down, striking his head against the ground and hurting it. 六．独立主格形式（分词复合结构或独立结构） 当上述的分词结构中主句的主语不是现在分词的动作发出者或过去分词的动作承受者时，分词有自己的主语 Mother (being) ill, he didn’t go to school. With mother being ill, he didn’t go to school. Cf: Being ill, he didn’t go to school. Weather permitting, we shall go to the city park. Cf: Permitted, we shall go to the city park. The question (being) settled, we wound up the meeting. With the question being settled, we wound up the meeting. He came into the room, his face (being) red with cold. He came into the room, with his face being read with cold.
小结过去分词作状语 [讲一讲] 1. 过去分词作状语表示被动或完成，但有些过去分词（短语）因来源于系表结构，作状语时不表动作而表状态。这样的过去分词（短语）常见的有: lost (迷路); seated (坐); absorbed in (全神贯注于); dressed in (穿着); tired of (厌烦)等。如：Absorbed in deep thought, he didn’t hear the sound. 因为沉浸在思考之中,所以他没听到那个声音。 2. 过去分词作状语来源于状语从句，在句中一般能作五种状语，即时间、原因、条件、让步和方式状语。如： Caught in a heavy rain, he was all wet. 因为淋了一场大雨，所以他全身湿透了。(Caught in a heavy rain 相当于原因状语从句Because he was caught in a heavy rain) Grown in rich soil, these seeds can grow fast. 如果种在肥沃的土壤里，这些种子能长得很快。 (Grown in rich soil相当于条件状语从句If these seeds are grown in rich soil) 注意： ①当从句的主语与主句的主语一致时，才可以把从句的主语省略，且省略掉的主语与其逻辑谓语是被动关系或如第一段中所讲的表示状态。 ②把状语从句改为过去分词作状语时有时还可保留连词，构成“连词+过去分词”结构作状语，即“while (when, once, until, if, though等连词)+过去分词”结构。如：When given a medical examination, you should keep calm. 当你做体格检查时要保持镇定。 Though beaten by the opposite team, the players didn’t lose heart. 尽管这些球员被对方球队打败了，但他们并没有灰心。 [练一练] I. 用所给词的适当形式填空，并与A-D的汉语翻译相匹配。 1.
