With the rapid change of social outlook and the emergence of new things, neologisms and neologisms have also become an eye-catching and vigorous field of vocabulary research. Since the reform and opening up, the social outlook has greatly changed , and new things have emerged one after another. New words and new expressions have also become an eye-catching, changing and vigorous field of vocabulary research. According to the definition of neologisms and neologisms, the author sorted out 100 neologisms and neologisms released in the past ten years (2011-2020) of "Chinese inventory of the top ten neologisms and neologisms of the year", supplemented some examples with reference to the report on the living conditions of Chinese language (2005-2020), and selected 200 high-frequency neologisms and neologisms in the past 15 years based on the standard of modern Chinese neologisms and neologisms (including more than 10000 entries from 1990 to 2016). From definition to Motivation and semantic classification, phonetic　and grammatical word-building features, word-making methods and teaching strategies ,all of the above are thoroughly analyzed from theory to practice.

There are many changes appeared with the Chinese degree adverbs as languages evolve over time, such as the emerging degree adverb ‘ju(巨)’ and the phrase structures like ‘巨多’, ‘巨好’, ‘巨痛’ are used in our daily communication commonly. This article discussed about the evolution mechanism of the Chinese emerging degree adverb ‘ju(巨)’s meaning in perspective of cognitive linguistics. First, we focused on the prototype meaning of ‘ju(巨)’ which is a adjective and the existing meaning of ‘ju(巨)’ which is used as a degree adverb. Second, we compared the image schema of the adjective ‘ju(巨)’ with the image schema of the degree adverb ‘ju(巨)’ and managed to find the differences between them. Then we studied the evolution mechanism of the degree adverb ‘ju(巨)’s meaning that is metaphor and made ‘ju(巨)’s metaphor mapping model. Third, we chose ‘巨多’, ‘巨好’ and ‘巨痛’ as examples by corpus-based study and used the conceptual blending theory to compared the conceptual blending spaces of them. Lastly, we found a general rule that can have reference significance to the study about the evolution of the other emerging degree adverbs, such as ‘狂’, ‘神’and so on. 저 자

Chinese tones has always been one of the key and difficult points in teaching Chinese to speakers of other language, therefore, the method of Chinese tones has always been the hot topic and focus in the field of teaching Chinese to speakers of other language too. Scholars have put forward advice and suggestions based on their own teaching practice, some of these methods are helpful in teaching Chinese tones. However, most of them are still relatively abstract and difficult for non-native Chinese learners (hereinafter referred to as “learners”) to learn tones, it is difficult to reach a consensus in the end. In recent years, more and more attentions have been paid to how to enhance learners' perception of tones. So, this paper will also start with strengthening the learners' perception about tones, elaborate that there is a corresponding relationship between the 5 degrees of the Method of Five Degrees Notation and the Numbered Musical Notation 1 (do), 2(re), 3 (mi), 4 (fa), 5 (sol), and put forward a teaching method, which combines the numbered musical notation as the tones' value of the four Chinese tones to sing and read(it is called "The Method of Singing and Reading in Combining the Numbers Musical Notation" in this paper). At the same time, combined with the author's teaching practice，this paper argues that the Method of Singing and Reading in Combining the Numbers Musical Notationand can make learners percept Chinese tones more directly, understand them more easily, and make their learning interest stronger, thus to get a good teaching result.
