Chapter Four Discussion and Analysis

4.1 Basic Statistics
The total number of word tokens in NEC amounts to 667,821 and the number ofword types in NEC is 21,541. The average frequency of NEC comes to 31,The number of words that appear in both NEC and CET4 wordlist is 3,954,accounting for 18.4% of the total words in NEC; their total frequencies in NEC amount‘ to 567,098, making up 84.9% of the total frequencies in NEC. The statistics aboveindicate that CET4 words occur fairly frequently in NEC although these words onlytake up 18.4% of the total words in NEC. It reveals that CET4 words do play a criticalrole in NEC and could be regarded as a precondition to have a good grasp of nauticalwords. Of the 3,954 overlapping words, the frequencies of 1,756 words are above the ,average frequency of NEC, which require extra emphasis during the process of learningCET4 words.In NEC words，17,574 words make no occurrence in CET4 wordlist. Their totalfrequencies amount to 100,723 in NEC words，making up 15.1%. Interestingly enough,the frequencies of words in NEC varies greatly ranging from 1 to 475 with the averagefrequency being 31; but the words with frequencies of 10 and below account for about91% of the whole non-CET4 words in NEC. It indicates that most words in NEC are notcommonly used, and the study of high frequency words is more meaningful andpractical.

Conclusion

Among the words which appear in NEC but not in CET4，399 words are above theaverage frequency，which are the focus of the research. They can be classified into fivecategories in terms of word formation. 144 of them fall into the category of derivation，accounting for 36.3%. Words of abbreviation come next to derivation with the numberof 37，making up 9.3%. The number of words formed in compounding is similar to thatof abbreviation, which is 33，accounting for 83%. Words formed in clipping come tofive，taking up 1,3%. And there is only one word formed in blending.NEC has its own word formation pattern although it shares a great deal ofcharacteristics with general English. Like in general English, derivation remains themost important means of word formation，bu本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
