7、: painter谓语: was exposed to宾语: history and cultures二、句子的三种基本类型如果按照句子的结构分类, 英文句子可分为三个类别: 简单句(Simple Sentence)、并列句(Compound Sentence)和复合句(Complex Sentence)。这里所说的结构, 主要是指句子中主语和谓语之间所构成的关系。1. 简单句(Simple Sentence)简单句只有一个主谓结构。句子可能有两个或更多的主语, 也可能有两个或更多的谓语, 但是句子中的主谓关系只有一个。简单句还可以有定语、状语等句子成分。*The people in the

8、meeting room remained silent. 会议室里的人保持沉默。*Many young artists are advised to learn by copying the masters. 许多年轻艺术家们被建议通过临摹大师们的作品来学习。2. 并列句(Compound Sentence)并列句有两个或两个以上存在并列、对等关系的主谓结构。从语法上讲, 这些主谓结构都能独立地表达意思, 没有从属关系。但是它们在意思或逻辑上有一定程度的内在联系, 使它们有必要构成并列句。在并列句中, 并列连词用来连接两个或几个主谓结构, 即连接平行对等(即互不从属)的分句。*Compute

9、rs are used widely in most countries now, and they are a sign of progress. 现在计算机在大多数国家被广泛使用, 它们是进步的标志。*She is tall, while her elder sister is short. 她很高, 而她姐姐很矮。3. 复合句(Complex Sentence)复合句由一个主句(Principal Clause)和一个或一个以上的从句(Subordinate Clause) 构成, 即有一个(或更多)主谓结构充当句子的某一(些)成分, 如主语、宾语、表语、定语、状语、同位语等。主语从句、

10、宾语从句、表语从句、同位语从句、定语从句和状语从句都属于复合句, 主句是全句的主体, 通常可以独立存在, 从句则只用作句子的一个成分, 不能独立。(1)主语从句作句子主语的从句叫主语从句。主语从句通常由从属连词that, whether, if和连接代词what, who, which, whatever, whoever以及连接副词how, when, where, why等词引导。that在句中无词义, 只起连接作用; 连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用, 在从句中充当从句的成分。有时为避免句子头重脚轻, 常用形式主语it代替主语从句放于句首, 而把主语从句置于句末

11、。*What the doctor is uncertain about is whether my mother will recover from the serious disease soon. 医生不能确定的是我母亲是否会很快从这个严重的疾病中康复。*It is recommended that the project not be started until all the preparations have been made. 建议在所有准备工作完成后再开始这项工程。(2)宾语从句用作宾语的从句叫宾语从句。宾语从句的引导词与主语从句、表语从句大致一样, 在句中可以作谓语动词或介

12、词及非谓语动词的宾语。that引导宾语从句时, that在句中不担任任何成分, 在口语或非正式的文体中常被省去, 但如从句是并列句时, 最后一个分句前的that不可省。在demand、order、suggest、decide、insist, desire, request, command, doubt等表示要求、命令、建议、决定等意义的动词后, 宾语从句常用“(should+) 动词原形”。who, whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等引导的宾语从句相当于特殊疑问句, 但句

13、子语序要用陈述语序。(3)表语从句在句中作表语的从句叫表语从句。表语从句的引导词与主语从句大致一样, 表语从句位于系动词后, 有时用as if引导。其基本结构为: 主语 + 系动词 +从句(若用that引导从句时, 不能省略)。(4)同位语从句同位语从句说明其前面的名词的具体内容。后跟同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。同位语从句和定语从句的区别: that引导

14、定语从句, 充当句子成分, 在从句中作宾语时可以省略; that引导同位语从句时, 没有实际意义, 不充当句子成分, 一般不能省略。如: *I had no idea that you were here. (that引导同位语从句, 不能省略)我不知道你在这里。*Have you got the idea (that) this book gives you of life in ancient Greece? (that引导定语从句, 作宾语, 可以省略)你明白这本书让你了解古希腊的生活了吗? (5)定语从句定语从句(Attributive Clauses)在句中作定语, 修饰一个名词或代

15、词, 被修饰的名词, 词组或代词即先行词。定语从句通常出现在先行词之后, 由关系词(关系代词或关系副词)引出。(6)状语从句状语从句 (Adverbial Clause) 指起副词作用的句子。可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其意义可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由从属连词引导, 也可以由词组(如the moment等)引起。从句位于句首或句中时通常用逗号与主句隔开, 位于句尾时可以不用逗号隔开。 【即学活用】在空白处填入适当的引导词(1)Nowadays consumers become more and more practi
