| As a fundamental discipline in linguistic study, the metrical study of vocabulary usage and distribution should be given significant emphasis in the study of basic vocabulary. Nowadays the metrical study in vocabulary is rare in China. Most of the studies focus on the usage of vocabulary and grammar and ignores the metrical study, which is the most fundamental methodology and is able to reflect problems in the most scientific way.This paper gets the statistics about the part of speech of vocabulary, grammar usage and their frequency of occurrence which appear in "primary Korean". Then this paper contrasts what is found in this paper with the findings in some other Chinese, North Korean, South Korean books and examines the causes for the difference and similarity among them."primary Korean " two volumes of a total of 23,071 words, not repeat the word as 3965, an average of 6.3 times the number of repeat. Repeated use of which is synonymous with the highest number, more than 50 times, followed by the interjection, adverb higher, followed by adjectives, verbs, word reached the average crown-shaped and, finally, slightly lower than the average of numerals and nouns.The first chapter of this paper mainly concentrates on the metrical study of the part of speech of the words and finds that nouns account for 2284 the most and about 45.76%, with verbs 1037 the second and accounting for 28.37%. This finding is congruent with our predication that the most frequently used words in the primary vocabulary structure (nouns+verbs) must be nouns and verbs. The paper lists all the vocabulary with all the eight parts of speech. The second chapter focuses on the metrical study on etymology. The findings are as follows:the indigenous words account for 36.97%, words from Chinese account for 59.63%, words from other countries except China account for 3.40%. This is roughly consistent with the percentage in the classification of etymology. Chapter vocabulary from semantic areas were classified respectively, from the people, clothes and medicine, social life, education, and physical arts, nature, feeling, understanding, action, status and so on are analyzed with the inherent common vocabulary words in account the conclusions of higher rates. Chapter IV of the book there were high-frequency words were summarized, respectively, corresponding to the number and frequency by the corresponding standards and the "Korean frequency dictionary," "Korean Education Vocabulary" and Chinese "Korean vocabulary grading standards" were analyzed.100 appear in textbooks and high-frequency words "North Korea frequency dictionary" of 100 words compared to repeat 43 words and repeat rate of 43%; textbooks, there 1,2 and 4 times more than the "Korean education, the term "repetition rates were obtained compared 16.17%,28.71%,47.39%, textbooks in more than one word in 3965 and" Korean vocabulary classification standard 1 "of 1115 words compared to repeat 51 words, repetition rate However,1.2%; and "Korean vocabulary classification standard 2" 2085 words compared to word repetition only 66, but 1.7% repeat rate. The fifth chapter conducts a poll among 16 students who was admitted in 2008 to Fudan University and finds the 100 most frequently used words. Based on this, the paper analyzes this with the 100 most frequently used words which appear in "primary Korean".25 repeated, repeat rate is 25%To sum up, the "primary Korean", the quantitative analysis showed that the frequency distribution of the material terms and higher repetition rate, we can see that the materials selected relatively objective appropriate vocabulary.Based on the metrical studies mentioned above and the statistics acquired, the paper assesses the vocabulary selection in "primary Korean" in an objective way and provides a statistical research base for vocabulary selection in the future education of the Korean language. |
