By using the Implicational Scale and Cluster Analysis, the paper compartmentalizes the acquisition process of 12 types of Chinese existence constructions by Thailand learners, and analyses their speech processing strategy during the acquisition process. The Chinese existence constructions that is a kind of special sentence types in Chinese grammar system is a indispensable and difficult part in the process of Chinese learning. On the one hand, dividing the acquisition process of Thailand learners and analyzing their speech processing strategy can improve the research of teaching Chinese as a second language. On the other hand, the study can make suggestions to the establishment of the outline, the compilation of the textbook, the method of the teaching and testing.The paper, at first, figures out the coefficient of three of the Implicational Scale by Thailand learners, which proves the three levels with the containable relations. And second, the study divides the acquisition process of The Chinese existence constructions into four stages by Cluster Analysis of SPSS. The three levels of Thailand learners all uses canonical order strategy, substitution strategy, appending strategy, insertion strategy, and elliptical strategy, but they can't partly or absolutely jump the restriction of these speech processing strategies. With the Chinese learning deeply, the three levels of Thailand learners could be out of some strategies of last acquisition progress and be into the next advancement. |
