雷得福德对句法结构的探索

Radford’s Exploration of Syntactic Structure

乔姆斯基创建的句法结构理论已经经历了半个多世纪的考验,乔姆斯基和他的继承者对句法结构的理论不断进行修改和完善。雷得福德就是其中的一员。本文对他在1997、2004及2009的三部著作中的几处修正和完善进行介绍和评价：（1）明确句法结构的原则;（2）DP和NP;（3）从IP到TP;4,关于合并的问题。肯定了雷得福德对句法结构探索的杰出贡献。

Theory of Syntactic Structure by Chomsky has been experienced more than half a century and constantly revised and perfected by the founder and his followers. Radford is one of them. This paper tried to have comments on four problems in his recent works （1997, 2004, 2009）： 1, Made clear the principle of syntactic structure; 2, DP and NP; 3, From IP to TP; 4, Merger with syntax.
