I think the most attractive part of this class is the Writing system in East Asian countries, especially the Chinese writing system. I learned that Chinese is a Logographic system that means each symbol stands for a meaningful unit and optionally for a sound. English has a different writing system it calls the Phonographic system and that means each symbol stands only for a sound. Chinese also have simple characters and these characters have just one graphic element, such as “金，木，水，火，土”. I also learned the “Radical”-gives clue to meaning and phonetic element-gives clue to the intended pronunciation. For example, “钉”  has radical is “金”, written in a simplified form and means : metal. “丁” is the phonetic element. I think it ’s interesting for the teacher to invite some other professor to give some special lectures in the classroom. This will make me more impressed with this class. I usually read book before class and do quiz. I will watch this class lecture after. This makes me memory deeper. I think this course has changed my understanding of linguistics. Before I took this class, I thought that the language origins of East Asian countries were the same. But right now I know these countries’ language structure and writing systems are completely different. I think this lass changed my way of thinking, I prefer to watch the teacher’s lecture after class.
