This study selected two kinds Chinese ambiguous sentence to discuss sentence comprehension strategy, from the view of reaction time and accuracy as dependent variables. The experimental results show that: 1. in both sentences, the subjects of reading time and the correct rate do not differ; 2. in both sentence structure, the reaction time of reconciliation words and ambiguous discrimination ones is significantly different; 3. the difference between two reaction time is very significant; 4. verb modifier structure and sentence structure in different locations on the reaction solution differ; 5. main effect of gender is not significant, and there is no interaction between sentences. These results prove when people are beginning to read, the syntactic structure has been established, and the understanding of the sentence is the result of integration, but some ambiguity in reading is immediate.
