| Cambodian has the syntactic component of complement, also has directional complements in the form of Chinese directional complements. Research of other foreign students acquisition of Chinese directional complements has attracted the attention of scholars, but it is blank to fill in directional complements acquisition of Cambodian students.The basis of this paper is that classification of fourteen lower Sentences of Chinese directional complements. From comparative analysis on the numberã€structure and semantics of the Chinese and Cambodian directional complements, we come to the correspondence of the Chinese and Cambodian’s directional complement and we predict sentences of Chinese directional complements learning difficulty level:sentence3,sentence5difficulty levels for one; sentence1, sentence7difficulty level for three; sentence2,4,6,8,10,12,14difficulty levels for four; sentence9, sentence11sentence13difficulty levels for five.Then through the study of correct sentences and wrong sentences on the fourteen lower Sentences of Chinese directional complements in Cambodian six grades (Primary Section:grade four, grade five, grade six; Secondary Section:grade seven, grade eight, grade ninth) student essay corpus of420,000, we use methods of the proper use of the relative frequency,the acquisition order interval and the implication scale method to test sentences acquisition order; and come to the final acquisition order and then use the Spearman correlation to inspect the prediction order and acquisition order and revise sentences acquisition order, the following conclusions:14lower sentences of Chinese directional complements can be divided into three acquisition interval:sentence8,sentence5>sentencel,sentence6,sentence7> sentence3,2,14,11,12,13,9,10,4.Examining wrong sentences, we find that misuse of V lai V qu is an unique type in the Cambodian students Acquisition; Alternatives error (46.7%) is the first category;Missing error class (38.6%), wrong order (13.6%), redundant order (1.1%) are in descending order. Then the reasons of migrate from the language learning strategies, teaching materials and teaching misleading are investigated.Finally we investigate the occurrence of sentences of Chinese directional complements in low-grade materials, the give the suggestions above the compilation of teaching materials and teaching graded recommendations focused on the different stages of learning. Then according to the acquisition situation of sentences of Chinese directional complements in different grades, we give the focus of teaching. We hope it is useful to the compilation of teaching materials and teaching. |
