X-bar理论
2011-09-18 20:42阅读:
X-bar理论试图揭示语言的词组结构的普遍规律,即所有的短语结构都按照一种模式进行组合。中心词(
head)X跟
补足语(
complement)形成一个结构X-bar。这个X-bar结构再跟一个
附加语(
adjunct)组合,形成一个更大的X-bar。这个X-bar跟一个
指别语(
specifier
)组合,形成一个短语结构XP。
例如:
(1) He studied linguistics at the university. /dje ndjtaem nza ltaeng
nxza-rxum.
V-bar: study (head) + linguistics
(complement). /njtaem(haed)+nza(complement)
V-bar: study linguistics (V-bar) + at the
university (adjunct). /njtaem nza
(v-bar)+ltaeng nxza-rxum(adjunct)
VP : he(specifier) + study linguistics at the university
(V-bar). /dje(specifier)+ndjtaen nza
ltaeng nxza-rxum(v-bar)
(2) The student of linguistics at the university.
//gtoeng ndjtaem nza ltaeng nxza-rxum hqi
nji
N-bar: student (head) + of linguistics (complement).
//gtoeng(head)+ndjtaem
nza(complement)
N-bar: student of linguistics (N-bar) + at the university
(adjunct). //gtoeng ndjtaem nza
(n-bar)+ltaeng nxza-rxum(complement)
NP: the (specifier) + student of linguistics at the university
(N-bar).//gtoeng ndjtaem nza ltaeng nxza-rxum
+hqi nji(specifier)
X-bar 在树形图上经常用 X', X''表示,前者代表
X+complement形成的结构,后者代表由X'+adjunct形成的结构。
X-bar的理论目标是:X-bar的结构模式应适用于各类具体的短语结构,如VP,NP,AP,PP,……;也适用于各种语言中的短语结构。
