and binding is a theory of syntax in the tradition of transformational grammar developed principally by Noam Chomsky in the 1980s.This theory is a radical revision of his earlier theories and was later revised in The Minimalist Program(1995)and several subsequent papers,the latest being Three Factors in Language Design(2005).GB Theory(管辖与约定理论)第6页,共38页,编辑于2022年,星期二The name refers to two central sub-theories of the theory:government,which is an abstract syntactic relation,and binding,which deals with the referents of pronouns,anaphors,and referential expressions.GB was the first theory to be based on the principles and parameters model of language,which also underlies the later developments of the Minimalist Program.GB

example of an interpretable feature is the plural inflection on regular English nouns,e.g.dogs.The word dogs can only be used to refer to several dogs,not a single dog,and so this inflection contributes to meaning,making it interpretable.English verbs are inflected according to the number of their subject(e.g.Dogs bite vs A dog bites),but this information is only interpretable once a relationship is formed between the subject and the verb,so movement of the subject is required.The Principle of

Representation第28页,共38页,编辑于2022年,星期二Bare Phrase Structure(BPS),is a minimalist theory of phrase structure(sentence building in simple terms).It was developed by Noam Chomsky.This theory contrast with the X-bar theory:Bare Phrase Structure第29页,共38页,编辑于2022年,星期二Contrast:1.BPS is explicitly derivational.2.BPS does not have a preconceived phrasal structure,while in X-Bar Theory,every phrase has a specifier,a head,and a complement.3.BPS permits only binary branching,while X-Bar Theory permits both binary and unary branching.4.BPS does not distinguish between a“head”and a“terminal”,while some versions of X-Bar Theory require such a distinction.第30页,共38页,编辑于2022年,星期二BPSincorporatestwobasicoperations:Merge(合并)andMove(移动).Merge is a function that takes two objects(say and)and merges them into an unordered set with a label(either or,in this case).The label identifies the properties of the phrase.Merge(,),。Bare Phrase Structure第31页,共38页,编辑于2022年,星期二For example,Merge can operate on the lexical items drink and water to give drink water.Note that the phrase drink water behaves more like the verb drink than like the noun water.That is,wherever we can put the verb drink we can usually put the phrase drink water.I like to _(drink)/(drink water).(Drinking/Drinking water)_ is fun.Bare Phrase Structure第32页,共38页,编辑于2022年,星期二So,we identify the phrase with a label.In the case of drink water,the label is drink since the phrase acts as a verb.For simplicity,we call this phrase a verb phrase or VP.Now if we were to Merge cold and water to get cold water,then we would have a noun phrase or NP with the label water.The reader can verify that the phrase cold water can appear in the same environments as the noun water in the three test sentences above.So,for drink water we have
