11、面;单个过去分词作定语往往置于被修饰词前面,过去分词短语作定语置于被修饰词后面。1)不定式作定语往往表示未发生的动作或通常发生的动作例句:The school to be built next month is intended for disabled children.下个月要建的学校是专为残疾儿童建的。例句:He is always the first to come and the last to leave.他总是第一个来最后一个走。2)动名词作定语往往表示某种用途A walking stick拐杖(=a stick which is used for

16、o be done,being done,done,having been done作定语的区别这四种形式都可以表示被动,同时都可作定语,但它们在作定语时,是有明显区别的。To be done表示“即将被做”,being done表示“正在被做”,done表示“已被做完”或表示“完成”,having been done一般不作限制性定语,作定语时,其前常用逗号与被修饰词隔开。例句:The question to be discussed tomorrow involves pollution.明天要讨论的问题涉及污染问题。例句:The question being disc

21、,never to return.他离家出走,再也没回来。例句:We arrived there only to find the meeting over.我们到达那里时却发现会议已经结束了。例句:The snow lasted a month,causing great damage.雪下了一个月,造成了巨大损失。例句:The pop star didn't turn up,disappointing all her fans.那位流行歌星没有露面,让她所有的歌迷都很失望。2)done,being done,having been done作状语的区别三者都表示被动,一般
22、说来表示伴随的状语可以用being done,但一般被done取代。Having been done往往强调发生在主句谓语动作之前完成,或已经持续一段时间的动作或状语,如果不强调时间先后或持续一段时间,则直接用done形式。例句:The boy was running along the street,(being) followed by a dog.小男孩沿着街道跑,后面跟着一条狗。例句:(Being) Led by the local guide,we went further into the virgin forest.在当地向导的带领下,我们走进了原始森林的深处。例句:Brough
23、t up abroad,he knows little about his hometown.他在国外长大,因此对自己的故乡了解得很少。例句:Having been well tended for half a year,the patient became far better.被细心照料半年后,这位病人情况好转了很多。(七)独立主格结构独立主格结构是一种特殊的结构,可以理解为一个在句中作状语的短语,主要有两部分构成:逻辑主语和逻辑谓语。独立主格结构用于修饰整个句子。其位置相当灵活,可置于主句前、主句中或主句末,常由逗号将其与主句分开。需特别注意的是,独立主格结构与主句之间不能使用任何连接词
24、。独立主格结构具有两个特点:独立主格的逻辑主语与句子的主语不同,它独立存在;独立主格结构一般用逗号与主句分开。独立主格结构主要分为两种,一种为“逻辑主语+非谓语动词”结构,一种是“逻辑主语+名词/形容词/副词/介词短语等”结构。此外,“with+复合宾语”结构也看作是独立主格结构的一种形式。1.非谓语动词独立主格结构“名词或代词+非谓语动词”结构构成的独立主格结构称为非谓语动词的独立主格结构。名词或代词和非谓语动词具有逻辑上的主谓关系。1)不定式构成的独立主格结构不定式构成的独立主格结构往往表示还未发生的行为或状态,在句中常作原因状语,偶尔作条件状语。例句:No one to wake me
25、up,I might be late for the first class.如果没人叫醒我,我会错过第一节课的。(=If no one wakes me up.)例句:Lots of work to do,I have to work extra hours.由于有很多工作要做,我不得不加班。(=As/Because I have lots of work to do.)2)现在分词构成的独立主格结构现在分词在句中作状语时,其逻辑主语必须是主句的主语;如果现在分词的逻辑主语与主句的主语不一致时,就应在动词的-ing形式前加上逻辑主语,这便构成了现在分词的独立主格结构,在句中常作时间状语、原因
26、状语、条件状语和方式状语。例句:All the students having sat down,the lecture began.(=After all the students having sat down.)所有学生坐好之后,讲座就开始了。(时间状语)例句:His hand waving in the air,the little boy ran away.(=As his hand was waving in the air.)小男孩的手在空中摇晃着跑开了。(伴随状语)例句:Time permitting,we will answer your questions after th

29、eading it.这本书包括很多有趣的图片,所以很多孩子喜欢阅读。表示条件例句:The book written in simple English,we can accept it more easily.(=If the book is written in simple English.)如果这本书用简易英语写的话,我们会更容易接受。例句:More time given,we can finish the book.(=If more time is given.)如果给我们更多的时间,我们能完成这项工作。注意!“名词/代词+非谓语动词”构成的独立主格结构中,运用不定式、现在分词和过去
30、分词意义是不同的。不定式往往表示没有发生或即将发生的动作或状态,现在分词表示正在进行的动作或状态,过去分词往往表示已经完成的行为。例句:So much work to do,I will have to work this Sunday.有这么多工作要做,这个星期天我不得不加班。例句:So much work done,I had a nice holiday.这么多的工作做完了,我过了一个愉快的假期。例句:So much work being done,I can't spare any minute.我正在做这么多的工作,一分钟也腾不出来。2.其他形式
31、的独立主格结构英语中最常见的独立主格结构是“逻辑主语+非谓语动词”结构,这种独立主格结构称为“有动词独立主格结构”,另外还有一类无动词独立主格结构,在英语中运用也比较频繁。这种结构往往看作是“名词/代词+being+表语”结构中省略了being,主要有如下几种情况。1)逻辑主语+名词名词或代词构成的独立主格结构形式为“逻辑主语+名词”,主要用于补充说明某一情况或表示方式。例句:Many people come to visit the city,most of them foreigners.很多人来参观这个城市,其中大多数是外国人。例句:Many Christmas gifts were s
