It first analyzed the words complication features of both language text books by words forms and words meaning and then studied the difference and the common place after the comparison of two language text books with a cognitive angle, which is divided into four parts-phonetic, writing, vocabulary .

There are two aspects of word meaning: referential meaning and connotative meaning.

Traditional approaches to lexical semantics, represented by componential analysis and semantic field theory, fail to give a satisfactory account of word meaning for they take word meaning as a stable and inherent attribute.

In this thesis I cope with the issue of word meaning.

In this paper, I shall explore the issue of word meaning together with its acquisition.

On the basis of the existing findings,the author divides words meaning into two categories: static meaning and pragmatic meaning.

In practical communications,the meaning system of the word does not stay in a self-closed or non-motion state but,in specific contexts,the meanings of words may change,thus forming particular pragmatic meanings.

The pragmatic meaning of the word is often unbalanced in realizing the value of the communicative function and the dominant degree is of difference.

This actual concept of a word in utterance,whether resulting in a narrower or broader literal concept or some combination of the two,is just the pragmatic meaning of a word in utterance.
