Application of Task-based Language Teaching in University Education of Functional Materials Specialty English Mingming Cheng1, a, Fei Wang2, b and Lijuan Wang2, c 1School of Humanities, Tianjin University of Finance and Economics，Tianjin 300222，China 2Institute of Power Source & Ecomaterials Science, Hebei University of Technology, Tianjin 300130, China achengmingming2011@126.com, bwangfei36777@163.com, cwljhh@yahoo.com.cn Keywords: functional materials, task-based language teaching, specialty English teaching Abstract.
Finally, teachers should generalize the common steps of preparation method for this kind of materials, which can be concluded as follows: choosing raw materials, pretreating raw materials, processing materials, characterizing and evaluating materials. 2.4 Effect of teaching practice Task-based language teaching establishes a relaxed and authentic context for communication, which can improve English listening ability, speaking ability and communication skills of students, and cultivate their self-learning ability and comprehensive skills of solving problems.
