Analyzing the Features of Spoken English Grammar

The three major factors, namely, shared context, constraints of real-time speech production, and the interactive nature of conversation, account for the emergence of spoken English grammar. These factors, to some extent, make spoken English grammar display the following features： low lexical density, restricted vocabulary, normal dysfluencies, simplicity of structure,and a high frequency of ellipsis,pronouns, particles, noun phrases, adjacency pairs, co-constructed units, questions and imperatives. Understanding spoken English grammar is important to the teaching of English language.
