“Cross-media reading literacy” refers to an individual’s comprehensive ability to acquire, perceive, reflect on, transfer and create linguistic symbolic information by integrating traditional media and electronic media. It is related to the development of national reading ability and even the promotion of China’s cultural soft power. It is a new challenge and new requirement of the information age. At present, constructing “cross-media reading literacy” in China still faces some predicaments, such as cramming as the main teaching method, the main bodies of education having weak critical consciousness and lack of media environment, making it difficult for people to adapt to the information society. Therefore, based on the MIL competency assessment framework by the UNESCO, this paper proposes that “cross-media reading literacy” can be constructed from five dimensions: reading receptivity, reading perception, reading reflection, reading transfer and reading creativity.
