[[abstract]]Drawn on the perspective of Systemic Functional Linguistics (SFL), this study aimed at analyzing students' writing characteristics of answering TIMSS 2003 constructed-response items, the relations among students' writing characteristics, and the differences of students’ writing characteristics between correct and incorrect responses, and further created a regression model on foregoing findings to predict if the response of an item is correct. The quality and quantity of students' writing responses were analyzed in terms of the syntax units, the syntax structure under the ideational function of SFL, and the textual function of SFL, nineteen writing characteristics in three categories in all were investigated. After getting rid of blank response data, one thousand and thirty-seven data from the responses of Taiwan 8th grade students participating in TIMSS 2003 main survey were stratification randomized by the percentage of correct and incorrect response data and analyzed statistically. Major findings were as followed : (a)The current conditions of nineteen writing characteristics of TIMSS 2003 entire, correct, and incorrect students’ responses. (b)The writing characteristics of correct students' responses were better than incorrect ones, but there was no significant difference between correct and incorrect students' responses in the three aspects of lexical density, the number of zero pronouns, and within-clause reasoning getting rid of responses with no reasoning. (c)The difference of writing characteristics between correct and incorrect response reflected that students whose answers were correct used a specific way of science language. (d)The prediction accuracy of the model created by students' writing characteristics was 87.8%, and the regression model was as followed : Logit(y)=-4.351-0.058×[the number of words] +1.198×[the number of clauses] +0.753×[the average depth of nominal groups] +0.987×[the average depth of clauses] -0.504×[the number of zero pronouns] -2.370×[the number of irretrievable zero pronouns] +1.997×[the number of correct reasoning] -2.757×[the number of incorrect reasoning]
