2、，is，are）表感官（feel，look，smell，sound，taste）表似乎（seem，appear），表变化（get，become，turn，grow，make，come，go，fall，run）表保持（remain，keep，stay，stand，lie）一、过去分词作状语的位置总是在系动词之后，构成系表结构，表示主语所处的状态或感受。例：1.The store is now closed. 商店已关闭了。2.The novel is well written. 这部小说写得很好。二、用法1. 过去分词可放在连系动词be，get，feel，remain，seem，look，bec

4、atisfied, surprised, married, known等。2. V-ed作表语，构成的系表结构与被动语态的区别:V-ed作表语，强调主语的特点或状态，相当于形容词;被动语态中，句子主语是动作的承受者，后面常跟by。例：The library is now closed(状态) The cup was broken by my little sister yesterday(动作)有些过去分词（短语）源于系表结构，作状语时不表动作而表状态。be dressed in; be lost in; be devoted to; be supposed to; be located in

5、; be buried in; be compared with; be seated; be prepared for; be determined to do; be tired of; be absorbed in; be born in; be occupied in 3. V-ed与V-ing作表语的区别：过去分词作表语多表示人自身的感受或事物自身的状态，常译作“感到的”；现在分词多表示事物具有的特性，常译作“令人的”。We are _(interest) in the film./ The film is _ (interest) to us. Michelle sounded _

6、(excite) to hear the news./ The news sounded _(excite).三、即学即练1. _ (seat) at the table, my father and I were talking about my job. 2. _ (dress) in her most beautiful skirt, the girl tried to make herself _ (notice) at the party.3.

8、ease） expression on his face we can guess he has passed the driving test.9. _(lost) in the forest, the boy burst into tears.10. You may be _ (worry) if you have a _ (worry) problem.过去分词作状语一、 过去分词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）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

9、等。过去分词的否定式是将not放在其前面。1.时间状语Looked at from a distance, the painting seems much more beautifulWhen it is looked at from a distance, the painting seems much more beautiful2.原因状语Done in a hurry, his homework was full of mistakes.Because it was done in a hurry, his homework was full of mistakes.3.条件状语Giv

11、wife.Summary:1. 作时间状语，可转换为when, while或after等引导的状语从句。2. 作条件状语，可转换为if, once或unless等引导的状语从句。3. 作原因状语，可转换为as, since或because等引导状语从句。4. 作方式或伴随状语 ，则可转换为and并列结构。5. 作让步状语 ，可转换为although, though或even if等引导的状语从句。二、注意事项: 1. 过去分词作状语: 过去分词作状语时，过去分词所表示的动作与句子的主语之间是逻辑上的动宾关系，即表被动。现在分词作状语:现在分词作状语时，现在分词所表示的动作与句子的主语之间是逻辑

12、上的主谓关系，即表主动。例：Seeing from the hill, you will find the city looks like a big garden.Seen from the hill, the city looks like a big garden.2. 过去分词作状语时，有时为了强调，前面可带有连词，如：when, while, if, though, as if, unless, until等，以使句意表达得更清楚。例：Unless constantly repeated, the English words are easily forgotten. When as

13、ked why she came here, the girl kept silent.3. 有些过去分词(短语)来源于系表结构，作状语时不表示被动而重在描述主语的状态。这样的过去分词及短语常见的有:lost (迷失的), seated (坐), hidden (隐藏的), lost/absorbed in (沉浸于), dressed in (穿着)等。例：Lost in thought, he didnt hear the bell.三、高考链接1.
