  1. SyntaxChapter 4

  2. Origin Syntax came originally from Greek. In linguistics, syn- "together” + tax- "an ordering” = "arrangement" is the study of the principles and rules for constructing sentences in natural languages.

  3. (Par. 4, p. 98) Formal accounts of syntax are based on establishing the basic constituents, namely, categories, from which word strings are formed.

  4. Phrase Structure Rules Phrase-structure rules are a way to describe a given language's syntax. They are used to break a natural language sentence down into its constituent parts (also known as syntactic categories) namely phrasal categories and lexical categories.

  5. Phrasal categories include the noun phrase, verb phrase, and prepositional phrase, etc.; lexical categories include noun, verb, adjective, adverb, and many others.

  6. Phrase structure rules are usually of the form A →B+C, meaning that the constituent A is separated into the two subconstituents B and C. Some examples are: S →NP+VP The show + rocks. NP →Det +N1 plenty of + snow

  7. Phrasal Categories • Noun phrase—NP: a tall man, the student, Kennedy • Verb phrase—VP: read, hit the ball, walk with a stick • Prepositional phrase--PP: with a stick, in the park • Adjective phrase—AdjP: quite rude • Adverb phrase—AdvP: very fast, swiftly

  8. S • NP VP The student V NP • likes the new linguistics professor.

  9. S • NP VP • V S • NP VP • V NP John insists (that) Mary take the piano class.

  10. To make a structural description of sentences, we shall describe various kinds of relations between words and phrases of sentences. There are two kinds of relations between them.

  11. Sequential Relations(顺序/横向关系)Par. 2, p. 98 i. Definition: In syntax, sequential or syntagmatic relation refers to the linear ordering of the words and the phrases within a sentence. ii. That is, a sentence is composed of minimal grammatical units called ultimate constituents (最终成分)in a particular order. iii. The---man---hit---the---ball linear

  12. Sentences are made up of clauses, which are made up of phrases, which are made up of words, which are made up of morphemes. Clauses, phrases, words are all constituents of a sentence on different levels.

  13. Hierarchical Relations(等级关系)par. 3, p. 98 i. Definition: Hierarchical relation shows us the inner layering of sentences. ii. What means can we use to reveal the hierarchical structure of a sentence? -- It’s IC analysis(直接成分分析法). iii. The // man /// hit // the / ball. hierarchical

  14. Background • In linguistics, immediate constituent analysis or IC analysis is a method of sentence analysis that was first mentioned by Leonard Bloomfield and developed further by Rulon Wells. The process reached a full blown strategy for analyzing sentence structure in the early works of Noam Chomsky.The practice is now widespread. Most tree structures employed to represent the syntactic structure of sentences are products of some form of IC-analysis.

  15. Immediate constituent This refers to the two parts that are yielded after each cut. An immediate constituent can be further segmented until we obtain the smallest grammatical unit—ultimate constituents.

  16. IC Analysis The analysis of a sentence in terms of its immediate constituents-- word groups (or phrases), which are in turn analyzed into the immediate constituents of their own, and the process goes on until the ultimate constituents are reached.

  17. Examples • Poor John ran away. • John left yesterday. • dis place ment

  18. More Examples • These apples are very sweet. These apples are very sweet These apples are very sweet very sweet

  19. Little Tom runs very fast. • Little Tom runs very fast. little Tom runs very fast Little Tom runs very fast very fast

  20. The advantages of IC Analysis Demonstrate the internal structure of sentences; Reduce ambiguity. (The same phrase or sentence may have two or more interpretations depending on the hierarchical arrangement of its constituents. Such a case is called structural ambiguity. 结构歧义)

  21. Leave the book on the shelf. Leave it there Don’t touch it

  22. My small child’s cot(小床) My small cot for a child. My cot for a small child The cot of my small child

  23. The son of Pharaoh’s daughter is the daughter of Pharaoh’s son.

  24. Problems of IC analysis 1 Binary division is not always effective. 首先,开始的时候有些提倡者坚持二元切分。任何结构体在任何层面都分成两个部分。但实际上并不总是如此。比如,old men and women是有歧义的,既可以是old + men and women的意思,也可以是 old men + and women。这两种方法中的任何一种都需要三分:第一种解释里的 men + and + women,第二种解释里的 old men + and + women。and只跟前边的部分组合或只跟随后的部分组合都是不可能的。

  25. Problems of IC analysis 2 • It cannot divide constructions with discontinuous constituents, e.g., make it up

  26. Summary My litter sister bought an old bike last week. NP/Sb VP/P My little sister bought an old bike last week Det/M NP/H VP/H NP/M My little sister bought an old bike last week A/M N/H V/V NP/C A/M N/H little sister bought an old bike last week Det/M NP/H an old bike A/M N/H old bike

  27. Construction (p. 99) Constituents are what a construction is made up of, and a construction is considered to have a hierarchical organization of constituents. Immediate constituents are immediately, directly, below the level of a construction.

  28. Endocentric and Exocentric Construction向心和离心结构 • The syntactic constructions analyzed are of two types: endocentric and exocentric constructions, depending on their distribution and therelation between their constituents.

  29. Endocentric(向心结构) • ENDOCENTRIC construction is one whose distribution is functionally equivalent to that of one or more of its constituents, i.e., a word or a group of words, which serves as a definable CENTER or HEAD. • An endocentric construction: a headed construction.

  30. 至少有一个直接成分与整体在语法功能上相同、在语义上受到相同的语义选择限制的句法结构。向心结构中与整体功能相同并且受到相同的语义选择限制的直接成分是它的核心。至少有一个直接成分与整体在语法功能上相同、在语义上受到相同的语义选择限制的句法结构。向心结构中与整体功能相同并且受到相同的语义选择限制的直接成分是它的核心。 • 结构的整体功能与其构成部分的一个成分功能相同。

  31. Typical endocentric constructions: noun phrases (the three small children), verb phrases (will have been working), adjective phrases (really very late) • The head: 1) the last constituent, or 2) at the beginning • the book on the shelf, • the man about whom I’ve been talking, • walked away immediately, • hot beyond endurance, • afraid of the talk

  32. Exocentric(离心结构) • EXOCENTRIC construction is just the opposite of endocentric construction. • It refers to a group of syntactically related words where none of the words is functionally equivalent to the group as a whole, that is, there is no definable “Center” or “Head” inside the group.

  33. Exocentric construction usually includes basic sentence, prepositional phrase, predicate (verb + object) construction, and connective (be + complement) construction. • Ex. • She likes dancing. • on the shelf • wrote a book • Is a teacher • The whole construction has a different grammatical function from either of its immediate constituents. They cannot substitute for each other.

  34. 系连式:直接成分一个是系连成分,另一个是表述成分:is a big man(是个大人物);is tired(疲劳了);became excited(激动起来);1ay in the corner motionless(躺在角落里不动)。

  35. 主谓式:直接成分一个是话题,另一个是说明:He is a big man(他是个大人物);She sings beautifully(她唱得极好);I saw him(见到他);That man just I don’t like(那个人我就是不喜欢);(She watched) us cross the street(〔她注视着〕我们穿过大街)。

  36. More Examples • 引导式:直接成分一个是引导成分,另一个是轴心:in the box(在盒子里);on the table(在桌子上);if he is going(如果他去);while we were there(我们在那儿的时候);saw John(看到了约翰);asked me a question(问我——个问题);asked me(问我)。

  37. Two subtypes of Endocentric constructions: COORDINATE constructions (并列结构) SUBORDINATE constructions (主从结构) • Coordinate construction: 1) there are more than one head 2) all are capable of serving as the head • Subordinateconstructions: There is only one head, with the head being dominantand the other constituents dependent.

  38. Coordination • A common syntactic pattern in English and other languages formed by grouping together two or more categories of the same type with the help of a conjunction such as and, but and or. This phenomenon is known as coordination. • These two or more words or phrases or clauses have equivalent syntactic status; each of the separate constituents can stand for the original construction functionally. • That is, in a coordinate sentence, two (or more) S constituents occur as daughters and co-heads of a higher S.

  39. Subordination • SUBORDINATION refers to the process or result of linking linguistic units so that they have different syntactic status, one being dependent upon the other, and usually a constituent of the other. • Thus the subordinate constituents are words which modify the Head. Consequently, they can be called modifiers.

  40. A subordinating construction contains a subordinator, which is a prep. (1), a particle (2), a subordinating conj. (3), and a dependent unit (4): (1) A teacher at the podium (2) A play to be performed by them (3) They left because they were tired. (4) A bird singing in the woods

  41. Sentence Types (句子类型) p. 100 simple Sentence complex non-simple compound 41

  42. Simple sentence 简单句 Definition:also called independent clause, which contains a subject and a verb, and it expresses a complete thought. Ex.: Jim and Mike play football every afternoon. Mary goes to the library and studies every day.

  43. Coordinate sentence并列句 Definition: contains two independent clauses joined by a coordinator(并列连词) : for, and, nor, but, or, yet, so (fanboys). Coordinators are often preceded by a comma. Ex.: I tried to speak Spanish, and my friend tried to speak English.  Lily went to play football, but Maria went shopping.

  44. Complex sentence 复杂句 Definition:A complex sentence has an independent clause (matrix clause) joined with one or more dependent clauses (embedded clause) by one or more subordinators(从属连词) , such as if, when, because, although. Ex.: As he is growing old, he seldom goes out. He isgrowing old, whereas he becomes healthier.

  45. Review of Terms • Immediate constituent; ultimate constituent • Construction -- endocentric / exocentric construction • Primary grammatical categories -- parts of speech=lexical categories • Secondary grammatical categories -- number, gender, concord, etc. • Functional categories -- subject, predicate, object, etc.

  46. Prescriptive Rules Don't start a sentence with a conjunction. Don't use contractions. Don't use sentence fragments. Don't end a sentence with a linking verb. Don't use dangling participles. Don't end a sentence with a preposition. Don't use an object pronoun for a subject pronoun in a conjoined subject. Don't use a plural pronoun to refer back to a singular noun like everyone, no-one, someone, and the like. Don't split infinitives. Use whom, not who, as the object of a verb or preposition.

  47. Choose the best answer 1. The head of the phrase : the city of Rome” is ___. A. the city B. Rome C. city D. the city and Rome.

  48. 2. The phrase “on the shelf” belongs to _____ construction. A. endocentric B. exocentric C. subordinate D. coordinate

  49. 3. The sentence “ They wanted to remain quiet and not to express themselves” is a ____ sentence. A. simple B. coordinate C. compound D. complex
