Abstract: An English word is composed of three parts, i.e. pronunciation, form, and meaning. During the process of learning a new word, its pronunciation and form should be made acquaintance before its meaning. The method of cycle training in learning English vocabulary is introduced in this paper, which includes three steps such as the P-F cycle training, the P-F-M cycle training, and revision of the new words. As a result, both the efficiency of word memory and the training of English language skills could be improved.
