1、2009-9 Grammatical Hierarchy& Sentence Structure语法层次与句子结构 Introduction 导论Lecture 112013-9Grammatical Hierarchy Grammar is the structural system of a language. The grammar of the English language is organized in to five ranks: （五个层次） sentence 句子 clause 分句 phrase 词组 word 词 morpheme 词素 Each rank is com

2、posed of one or more than one grammatical unit of the immediate lower rank. A full sentence can generally be segmented rank by rank down to its smallest constituentsthe morpheme. Syntax (句法)Morphology (词法)2 我们可以通过切分把句子进行层层切分，分成最小的构成成分。例如：句子：Paul is one of the nicest schoolboys I know.分句：Paul is one

3、of the nicest schoolboys（主要分句） （who/whom) I know （从属分句）词组：one of the nicest schoolboys （名词词组） of the nicest schoolboys （介词词组） the nicest schoolboys （名词词组） is one of the nicest schoolboys （动词词组） know (whom) （动词词组）词： Paul, one, schoolboys, I, of, nicest, know, is, the词素：Paul, one, school, boy, -s, I,

Morphemes (词素)词素是最小的语法单位，也是最小的语义单位。The morpheme is the minimum or smallest grammatical unit, also the smallest meaningful element of speech. Morphem

5、es fall into two categories: （分为两大类）free morphemes and bound morphemes.5 the smallest meaningful element of speech (最小语义单位) free morpheme bound morpheme (自由词素) (粘附词素) complete meaning; incomplete meaning; stand by itself as cant stand alone, simple word attached to other forms e.g. boy, girl, take,

6、e.g. kindness, unkind, school, kind unkindness, kindlyMorpheme词素 61）Free morphemes (自由词素）本身具有完整意义并能作为“简单词”而单独使用的词素。e.g. boy girl desk kind give take2) Bound morphemes (粘附词素）本身没有完整意义，不能单独使用，必须粘附在自由词素或其他形式上才能表示出意义的词素。e.g. anti-war Marxist unlucky postwar movement co-existence72. Words (词)The word is c

7、omposed of one or more than one morpheme. Words can be classified in two ways: 1) Classification in terms of word-formation （根据构词法分类） 2) Classification in terms of grammatical function （根据语法功能分类）2009-99 1）简单词、派生词、复合词 In terms of word-formation, words can be divided into:a) Simple Word (简单词）b) Deriva

8、tive （派生词）c) Compound Word（合成词）2009-9102009-911 Simple Word (简单词）又叫“单词素词”（morpheme word), 由单一自由词素构成，多半是一些短小的词，如：at, by, foot, take, make 等b) Derivative （派生词）由词根加派生词缀构成，同一词根加不同词缀可表示不同的意义或不同的词性。如：unfair, nonsmoker, misjudge, overeat, international, belittle 等c) Compound Word（复合词）通常由两个或两个以上自由词素构成。如： de

9、adline, handbook, driveway, toothpick, downfall 等 2009-9132）封闭词类和开放词类In terms of grammatical function, words can be divided into two main groups:a) Closed Class (封闭词类) 封闭词类指所有的功能词，包括:介词 (Preposition), 如：in, of, on, without代词 (Pronoun), 如：you, he, one, which限定词 (Determiner), 如：a, the, this连词 (Conjunc

10、tion), 如：and, or, but助动词 (Auxiliary), 如：do，can, may2009-914 b) Open Class (开放词类）开放词类指各种实义词，包括：名词 (Noun)， 如：man, Paris, drama形容词 (Adjective), 如：old, big, cheap副词 (Adverb), 如：here, there, late 主动词 (Main Verb),如：work, give, make此外还有基数词 (Cardinal Numeral)，序数词(Ordinal Numeral)，感叹词(Interjection)是介乎“封闭”与“开

11、放”之间的词类2009-9153. Phrases （词组）词组是由一个或一个以上的词构成的语法单位The phrase is composed of one or more than one word.

18、) Independent and dependent clauses An independent clause (独立分句） is a clause that can stand by itself and act as a complete utterance. e.g. He knows everything about it.
