The major findings were: 1) The inter-group comparison of picture vocabulary showed that low achievers were inferior to middle and high achievers on both 3 and 6 �� grade. 2) The comparison of oral repetition ability showed that, on both grade, high achievers were superior to middle achievers and middle achievers were superior to low achievers. 3) The percentage correct of four sentence patterns of oral repetition were all increased from low to high achievers. 4) The correlation coefficients between oral repetition and reading comprehension were.663 and.484 for 3 and 6 �� graders. The coefficients between picture vocabulary and reading comprehension were.572 and.596 for 3 and 6 �� graders. 5) The development of picture vocabulary was different among three achievement level students.
