Abstract: In the light of "Bilingual Structure" theory, the paper explores the embodiment of interaction between language and thinking in Chinese college students' English reading process.Based on an experiment, it makes a statistic analysis on the involving force between mother language and foreign language.The results show that Chinese has not only direct impact on college students' reading process, but indirect influences on it by affecting their English level; and college students' awareness and ability of knowing how to understand English by making full use of Chinese are expected to be improved.
