Four types of punctuation errors are listed as follows: 1) errors caused by negative transfer from the native language;2) errors related to syntactic-semantic structures;3) errors with regard to lexical-semantic structures,and 4) errors resulting from stylistic misuse.

Semantic primitive is an important concept in lexical semantics.

In nutshell,the paper argues for the probability and necessity of a renewed cooperation between etymology and lexical semantics in the academic context of contemporary Chinese linguistics in particular.

This article reviews the publication background and highlights the thoughts of Syntactic Structures (Chomsky 1957), the comments of European and American scholars, its development over the structural linguistics and its influence on Chomsky s later works.

The paper concludes four parts:the developing academic background of structural linguistics,concerning the research of Saussure s linguistic theory,structural linguistics:interpretation and critique,and construction of research procedure.

Saussure was the first person who put forward the concept of "systems" for linguistics,as most linguists later saw as "structures",which opened a new era of linguistics the era of structural linguistics.

Reviewing the past, Chinese grammar study has changed from traditional grammar to historical grammar, from structuralism grammar to "Duoyuan Hubu" theories system.

To understand the development of linguistics must start from historical comparative linguistics and structuralist linguistics, which can outline the development of linguistics in Europe and the United States.
