Abstract：Abstract:By adopting Skehan’s list of salient features for describing language tasks as the theoretical framework, the present study examines how CET 4 testtakers in China understand the descriptors of reading proficiency at the levels from B1 to C1 in the CEFR (Common European Framework of Reference for Languages). The study results show that the task features of code complexity (language difficulty), topic familiarity, time pressure and task control (task conditions and limitations) have significant impacts on the subjects evaluation of the descriptors. The effect of task processing complexity (cognitive loading) is, however, equivocal. The study is expected to provide insights for the development and revision of Chinas Standards of English.
