1、专业四八级英语专业四级考试语法汇总专业四八级英语专业四级考试语法汇总独立主格结构独立主格结构（Independent Genitive）有两部分组成，前一部份是名词或者代词，后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。前后两部分具有逻辑主谓关系。独立主格结构在句中做状语，多用于书面语。 独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。非谓语动词作状语，其逻辑主语须与主句主语保持一致。若不一致，非谓语动词形式须另带主语，从而构成复合结构的形式作状语。这种结构称为“独立结构”。其中，非谓语动词主动用现在分词，被动用过去分词。 非谓语动词及其
2、短语前面带有逻辑主语，逻辑主语的代词又是主格，故常称为“独立主格”。“独立结构”在句中起状语作用，相当于状语从句，表示时间、原因、条件、方式或伴随等情况。 功能独立主格结构主要用于描绘性文字中，其作用相当于一个状语从句，常用来表示时间、原因、条件、行为方式或伴随情况等。例如： 表示时间The meeting being over, all of us went home. 开完会后我们都回家了。 Her work being done, she sat down for a cup of tea. 她干完了活，坐下来喝茶。 表示条件The condition being favorable,

4、 conductors, and silver is the best of all.) 用法独立主格结构主要表示谓语动词发生的时间、原因、条件或伴随情况等，相当于一个状语从句或并列句。 用作时间状语The work done (=After the work had been done), we went home. 工作完成后，我们就回家了。 用作条件状语Weather permitting (=If weather permits), they will go on an outing to the beach tomorrow. 如果天气允许的话，他们将在明天组织一次海滨小游。 用作原

18、是星期天，我们去做了礼拜。 (2)在There being+名词的结构中。如：There being no bus, we had to go home on foot.因为没有公共汽车，所以我们不得不步行回家。 3. 在“名词（或代词）+介词短语”构成的独立主格结构中，一般不用形容词性物主代词和冠词。如： Miss Smith entered the classroom, book in hand.史密斯小姐走进了课室，手里拿着一本书。比较with的复合结构。如：Miss Smith entered the classroom, with a book in her hand. 4. 独立主
19、格结构没有所有格形式The chief-editor arriving, we began the meeting. 主编来了，我们开始开会。(比较动名词复合结构。) 示例请看下面一道题： Not far from the school there was a garden, _ owner seated in it playing chess with his little grandson every afternoon. A. its B. whose C. which D. that 【分析】此题很容易误选B，许多同学会认为句中逗号后是一个非限制性的定语从句，whose 在定语从句中用
20、作定语修饰其后的名词 owner。此分析从表面上看，似乎天衣无缝，但实质上是错的，原因是空格后根本不是一个句子，因为没有谓语。尽管句中有两个动词，但它们都是非谓语动词。也许有的同学认为，其中的 seated 可视为谓语动词，但是注意，seat 用作动词时，它总是及物的，其后要么接宾语，要么它就用于被动语态，所以若在 seated 前加上助动词 is，则可以选择B（当然若将 seated 改为sitting，也应选择A）。所以此题最佳答案选A。 请再看一个类似的例子： (1) He wrote a lot of novels, many of _ translated into foreign
21、languages. A. it B. them C. which D. that (2) He wrote a lot of novels, many of _ were translated into foreign languages.A. it B. them C. which D. that 第(1)应选B，而不能选C，是因为句中的 translated 是过去分词(非谓语动词)，若选C，则该从句无谓语；第(2)应选C，该句是典型的非限制性定语从句，因为该句修饰的是前面的novels，即指物，所以只能用which做of的宾语，故本题选C。 再请看下面一例： (3) He wrote
22、a lot of novels, and many of _ were translated into foreign languages. A. it B. them C. which D. that 【分析】此题与上面的第(2)题不同，两句间多了一个并列连词and，说明这是一个并列句，故应选B，则不能选C。 请做做以下三题(答案均为B)： (1) There I met several people, two of _ being foreigners.（独立主格结构） A. which B. them C. whom D. that (2) There I met several peo
23、ple, two of _ were foreigners. （非限制性定语从句） A. which B. whom C. who D. that (3) There I met several people, and two of _ were foreigners.（两个句子） A. which B. them C. whom D. that非限制性定语从句的五个“不能”一、 非限制性定语从句通常不能用that引导。如： 1. I like the book, which was bought yesterday. 我喜欢这本书，这是昨天买的。 2. I like the book whi
24、ch / that was bought yesterday. 我喜欢昨天买的那本书。 二、 非限制性定语从句不能用why引导。要用for which代替why。如： 1. I had told them the reason, for which I didnt attend the meeting. 我已经把理由告诉了他们，为此我没有去开会。 2. I had told them the reason why I didnt attend the meeting. 我告诉了他们我不去开会的理由。(限制性定语从句“the reason why.”是常见搭配。) 三、 非限制性定语从句置于句首
25、时，不能用which引导。关系代词as引导非限制性定语从句位置比较灵活，可以放主句前，也可以放主句后。如： 1. As I expected, he didnt believe me. 正如我所预料的，他不相信我。 2. She heard a terrible noise, which brought her heart into her mouth. 她听到一个可怕的声音，这让她把心都提到嗓子眼了。 四、 非限制性定语从句由“介词+关系代词”引导时，其中的关系代词不能用as。如： 1. He bought the car for more than $20,000, with which
26、his father was angry. 他花两万多美元买了这辆车，他父亲对此很生气。 2. I finished my work ahead of time, after which I sat some time reading the newspaper. 我提前干完了我的活，随后我坐着看了一会儿报纸。 五、 在非限制性定语从句中，指人的关系代词作宾语时，只能用宾格whom; 不能用who替换，也不能省略。如： 1. Do you know Tom, whom we talked about? 你认识汤姆吗? 我们谈到过他。 2. This book, which you can ge
27、t at any bookshop, will give you all the information you need. 这本书会给你提供所有你需要的资料，它在任何一家书店都能买到。(非限制性定语从句中引导词在从句中作宾语，无论指人还是指物都不能省略。)由who、whom、whose引导的非限制性定语从句1. who引导的非限制性定语从句Our guide，who was a French Canadian，was an excellent cook.我们的向导，一个法裔加拿大人，擅长于烹调。Then he met Mary，who invited him to a party.后来他遇到
28、玛丽，玛丽邀请他去参加晚会。My gardener，who is very pessimistic，says that there will be no apples this year.我家的园丁非常悲观，他说今年将不结苹果。2. whom引导的非限制性定语从句关系代词whom用于指人，在句中作动词宾语和介词宾语，作介词宾语时，介词可位于句末。如：Peter, whom you met in London, is now back in Paris.彼得现在回巴黎了，你在伦敦见过他。Mr Smith，from whom I have learned a lot，is a famous sci
29、entist.史密斯先生是一位著名的科学家，我从他那儿学了许多东西。3. whose引导的非限制性定语从句whose是关系代词who的所有格形式，在从句中作定语。whose通常指人，也可指动物或无生命的事物。如：The boy, whose father is an engineer, studies very hard.那位小男孩学习很努力，他的父亲是位工程师。Above the trees are the mountains whose magnificence the river faithfully reflects on the surface. 在树林的高处是山，其壮丽的景色完全映

They work hard, dont they? 句子类型：一种是反义的附加疑问句，一种是非反义的附加疑问句。 读法规则附加疑问句陈述部分用降调，问句部分可升可降。提问者对陈述部分把握较大时，问句部分用降调；反之用升调。 速记方法前肯后否，前否后肯，前be后be，前无be后助,时态一致。 主语一般词语附加疑问句中主语用和主句一致的主语，用主格。 附加疑问句随从句。 不定代词当陈述部分的主语时 ( 1 )用one时，后面的疑问句可用one/he. (2)everything, anything, nothing, something时， 附加疑问句中主语用it 不用 they （3）this, that,或those,
