12.普遍语法General grammar
A system of linguistic knowledge which consists of some general principles and parameters about nature language.
13.移动α 规则Move α
  A general movement rule accounting for the syntactic behavior of any constituent movement.
14.句法移位Syntactic movement
  Syntactic movement occurs when a constituent moves out of its original place to a new position.
15.转换原则Transformation rules
  Syntactic movement is dictated by rules traditionally called transformational rules, whose operation may change the syntactic representation of a sentence.
16.X标杆理论X-bar theory
  A general and highly abstract schema that collapses all phrases structure rules into a single format :X”→（Spec）X(Compl).
一种泛指的、高度抽象的图示，它把所有的词组结构规则概括为一种程式
X”→（Spec）X(Compl)
 
   a:        X”                    b: X”      Spec X’
 Spec      X’                        X’       X compl
        X          complement  
 
NP ’the student who likes linguistics’ consists of Det, N and S with Det being the Specifier ,N the head, S the complement. NP(…)有冠词、名词和子句组成，冠词是指示语，名词是核心词，子句是补足语。
二、知识点
1.syntax这个单词源于Greek,本义是arrangement.
2.我们把syntax的学习看作 a system of rules that govern the formation of grammatical sentence.
3.A major goal of linguistics is to show with a consistent and explicit grammatical theory how syntactic rules account for this grammatical knowledge.
4.判断题：the syntactic rules of any language are finite in number ,and yet there is no limit to the number of sentences native speakers of that language are able to produce and comprehend.
5.判断题:A finite verb, informally called the main verb of a sentence, expresses existence, action or occurrence which is limited by person, number, tense and mood.
一个限定动词被非正式称为句中主要动词，表达了人称、数、时态、语气限定的存在、行动或事件。
6.句子的分类             simple sentence
 Types of sentences   coordinate or compound sentence
                                Complex sentence
简单句---It consists of a single clause which contains a subject and a predicate and stands alone as its own sentence.
并列句合成句-It contains two clauses joined by a linking word called coordinating conjunction, such as “but”, ”and”. ect.
复合句—It contains two or more clauses, one of which is incorporated into the other.
复合句的特点：
  ⑴An embedded clause functions as a grammatical unit in its matrix clause
⑵Most embedded clauses require an introductory word called a Subordinator, such as ”that”
⑶An embedded clause may not function as a grammatically well-formed sentence if it stands independently as a simple sentence unless its form changes.
  子句是一个语法单位，大部分子句要带一个被称为从属连词的引导词，如果子句作为秒年第秒年句单独存在，它可能不是一个合乎规范的句子，除非改变他的形式。
7.when a sentence is uttered or written down, the words of the sentence are produced one after another in a sequence.
8.The hierarchical nature of sentence structure句子结构层次特点
sentences are organized with words of the same syntactic category, such as noun phrase NP or verb phrase VP, grouped together.
 9.The points at which the tree braches at various levels are called Branching    nodes分叉点
10.In addition to the use of structural tree diagrams, linguists may show the hierarchical structure of sentences by using brackets and subscript labels.
