This study examined "signals" of relationships between sentences that might be helpful in teaching reading to non-native speakers of English. Logical relationships were given special attention and classified to determine if they could be contained within a limited list to be used for teaching purposes. Five hundred paragraphs (2,720 sentences) were examined using a list based on the "meaningful relationships" discussed by Jones and Faulkner in "Writing Good Prose." The relationships examined were found to be adequately covered by 18 categories: Alternative, Amplification, Answer, Cause, Comparison, Contrast, Definition, Evaluation, Evidence, Example, Generalization, Inference, Parallel Idea, Question, Related Action, Restatement, Result, and Summary. Also examined were the structural and lexical signals of subordination; a marginal marking system was used to indicate coordination, subordination, and levels of generality. The analysis was exploratory, and findings were expected only to indicate promising possibilities for further investigation. (Author/LH)
