1、精选优质文档-倾情为你奉上英语句子结构句子是按照一定的语法规律组成的,表达一个完整的意义。一个句子一般由两部分构成,即主语部分和谓语部分,这两部分也叫做句子的主要成分。句子的次要成分包括宾语,定语,状语,表语等。句子成分是句子中起一定功用的组成部分。一句子成分分析1 主语(subject)句子的主体,全句述说的对象。一般由名词,代词,数词,不定式,动名词,从句担任,常置于句首。Professor Zhang is a famous scientist.(名词)I like football. (主格代词)Two plus five is seven. (数词)To swim in the Li
2、jiang River is a great pleasure. (不定式)Smoking dose harm to the health. (动名词)When we are going to have an English has not been decided.(主语从句)2. 谓语(predicate)对主语加以陈述,表示主语的行为或状态,常用动词或者动词词组担任,放在主语的后面。谓语分为简单谓语和复合谓语(1).简单谓语由一个动词或者动词短语构成The train leaves at 6 oclock.(动词)She takes good care of her mother.(动词
3、短语)(2).复合谓语由情态动词或其他助动词加动词原形构成You may keep the book for two weeks.(情态动词+动词原形)She doesnt seem to like dancing.(助动词do+动词原形)He has caught a bad cold.(助动词has+动词原形)补充:协助主要动词构成谓语动词的词叫助动词(Auxiliary Verb)。被协助的动词称作主要动词(Main Verb)。最常用的助动词有:be, do, have, shall, will, should, would. 助动词自身没有词义,不可单独使用,例如: He doesn
4、t like English. 他不喜欢英语。 (doesnt是助动词,无词义;like是主要动词,有词义)由系动词加表语构成(即主系表结构)We are students. (状态系动词be+表语)He looked a bit excited.(表象系动词look+表语)补充:亦称联系动词(Link Verb),作为系动词。有些不具词义;有些具有词义,但不能单独用作,后边必须跟(亦称),构成系表结构说明主语的状况、性质、特征等情况。1状态系动词 用来表示主语状态,只有be一词,例如: He is a teacher.他是一名教师。(is与补足语一起说明主语的身份。) 2持续系动词 用来表示
5、主语继续或保持一种状况或态度,主要有keep, rest, stay, lie, remain, stand. 例如: He always kept silent at meeting.他开会时总保持沉默。 This matter rests a mystery.此事仍是一个谜。 3表像系动词 用来表示看起来像这一概念,主要有seem, appear, look, 例如: He looks tired.他看起来很累。 He seems (to be) very sad.他看起来很伤心。 4感官系动词 感官系动词主要有feel, smell, sound, taste, 例如: This kin

8、actises speaking English every day. (动名词)I enjoy listening to popular music. (动名词短语)Can you tell me where the No.3 bus stop is? (宾语从句)补充:宾语的种类:(1)直接宾语表示动作的承受者或结果,通常指物。Lend me your dictionary, please. (me是间宾,dictionary是直宾)(2)间接宾语表示动作所向或所为的人或物,通常指人。间接宾语一般位于直接宾语之前,也可位于之后,但此时在它前面必须加介词toThe company sent
9、us a few computers last year.He sent a birthday gift to me yesterday.(3)复合宾语有些动词出了接宾语外,还需要一个词来说明宾语的身份或状态,以补充其意义的不足,这样的词或短语叫做宾语补足语。宾语和宾语补足语一起构成复合宾语,他们在逻辑上有主谓关系。如果直接宾语是不定式,动名词或从句,常用it作形式宾语)They elected him their monitor.(代词+名词)I found the baby always happy. (名词+形容词)I find it easy to answer this questi
10、on. (it作形式宾语)4. 宾补(objective complement) 有些及物动词,除有一个直接宾语外还要有一个宾语补足语来补充说明宾语的情况 。这些及物动词常见的有make, let, have, get, find, call, see, consider, cause等。Electricity can make a machine run.I consider the book too expensive.5. 表语(predicative)用来说明主语的性质,特征或状态。一般由名词或者形容词担任。置于系动词之后。He is a student. (名词)This table
11、 is long. (形容词)6 定语(attributive)对名词或代词起修饰、限定作用的词、短语或句子,汉语中常用的表示,通常位于被修饰的成分前(注意:它和表语的区别在于定语后面可以直接接名词,表语必须接在系动词之后)This is a red sun.He is a tall boy.说明1:当定语修饰不定代词如:nothing , anything , everything , something 等时,定语要放在其后作后置定语。 I tell him something interesting .说明2:不定式、短语或从句作定语时,也放在被修饰的名词之后。 The boys in
12、the room are in Class Ten. 7 状语(adverbial)用以修饰adj. /adv. /v.及整个句子,说明动作或状态特征的句子成分,位置灵活。修饰形容词或副词时放在它们之前。修饰动词时可以放在动词之前,也可以放在动词之后。通常由副词担任。The bag is too heavy.(修饰形容词heavy,置于之前)He went out just now. (修饰副词now,置于之前)I often write to him. (修饰动词write,置于之前)The students study hard.(修饰动词 study,置于之后)小结:通常情况下,主语和宾
13、语前的成分是定语,谓语前的成分是状语,时间词作状语放在句子后面。句子的成分分布如下:(定语) 主语 (状语) 谓语 (定语) 宾语 (状语)如:(The tall) boy (often) go (to the big) zoo.(The happy) child went (his) home(yesterday).二句子类型句子主要有三种类型:简单句,并列句,复合句。(一)简单句英语句子看上去纷繁庞杂,但仔细观察不外乎五个基本句式。这五个基本句式可以演变出多种复杂的英语句子。我们常说的五大句型就是指的简单句的五种类型。换言之,绝大多数英语句子都是由这五个基本句式生成的。这五个基本句式如下:
14、1. Things changed.主 + 谓2. Trees are green.主 + 系 + 表3. We dont beat children.主 + 谓 + 宾4. He gave his sister the piano.主+谓 +间接宾语+直接宾语5. I found the book easy. 主+谓 + 宾 + 宾补(二).并列句由并列连词连接、含有两个或更多主谓结构的句子叫并列句。一、表示转折对比关系的并列连词1. but但是,可是,而,却连接两个简单句,有时句中某些词可以省略;连接两个并列成分,可以放在一个句子的句首,后面不接逗号。例:I hope you dont m
15、ind me asking,but where did you buy those shoes?2. yet但是;尽管如此可连接两个句子,用逗号分开,也可在yet 前加and ,还可以放在一个句子的句首。例:The car is old, yet it is in good condition. 这辆车旧了,但车况很好。3. while而,但是,可是,却while 作连词用时,可表示对比或转折关系。例:I do every single bit of housework while my husband Bob just does the dishes now and then.二、表示因果关
16、系的并列连词1. for因为由并列连词for 引导的分句常置于句子后部,而且常用逗号与前面的分句隔开。for 分句主要是对前一分句补充说明理由或推断原因。for 分句不能用来回答why 问句。例:I did my best not to show pleasure,but what I was feeling was pure happiness,for my words had the power to make people laugh.2. so 因此可以连接两个句子,中间有时用逗号隔开;也可在so前加and ;还可以放在一个句子的句首。例:The shop doesnt open un
17、til 11 a.m.,so it loses a lot of business.三、表示选择关系的连词oror连接并列成分时,意为“或者,还是”;用于否定句中,意为“也不”,这时不宜用and ;还有“否则,要不然”之意,相当于otherwise.例:Would you like a cup of coffee or shall we get down to businessright away?四、表示并列关系的并列连词1. and和,同,与,又,并且例:Stand over there and youll be able to see it better.2. not only but
18、also 不仅而且例:Not only I but also Jane and Mary are tired of having one examinationafter another.3. neither nor既不也不例:They worked neither for fame nor for personal gains.他们工作一不为名,二不为利。4. both and既又例:A man should have both courage and wisdom.人既要有勇气又要有智慧。五、其他并列连词1. not but不是而是It was not the bones of an an
19、imal but of a human being. 这不是一只动物的骨头,而是人的骨头。2. rather than而不是;与其宁愿Rather than ride on a crowded bus , he always prefers to ride a bicycle.3. when 正当那时,相当于and at that timeJasmine was holidaying with her family in a wildlife park when shewas bitten on the leg by a lion.(三) 复合句复合句是由一个主句加上一个或一个以上的从句构成的
