Abstract: Based on WoS, we collected a total of 1,578 papers related to adolescent reading from 2000 to 2017. By selecting keywords as the units of analysis, using co-word analysis and cluster analysis as methods, and adopting SciMAT as the knowledge mapping tool, this paper identified the theme evolution paths of teenager’s reading since the 21st century. Research demonstrated that the most important evolution paths were “reading-disabilities” and “comprehension”. The two themes went through the process of“learningdisabilities”, “skills”, “instruction”, “reading-comprehension”, “phonological-awareness”, “individualdifferences”, and finally changed into themes of “reading-disabilities”, “comprehension” and “readingcomprehension”, which continued to be hot topics. The evolution path from “reading-motivation” through “achievement” and “motivation” to “intrinsic-motivation” hasbecome mature, whereas the professional themes, such as “gender-differencfs”, “indivduals” and “instructionai-strategies”, emerged at different times and soon disappeared.
