As one of the required courses, grammar has been taught to English majors in universities and colleges for years. It is known that “grammar is a set of rules that define how words (or parts of words) are combined or changed to form acceptable
units of meaning within a language” (Penny, 2000). Guaranteeing the accuracy of the sentences mainly depends on
the learner’s mastery of grammar. Grammar, which is an indispensable part of a language, is so important that the
teachers and students have always attached great importance to grammar teaching and learning. For the
above-mentioned reasons, how to make grammar teaching and learning effective and efficient is an important task
for both English teachers and researchers.
