English learning involves memorization and practice of vocabularies. It is widely known that English learning should pay great attention to vocabulary learning, and what´s more, the vocabulary learning is considered to be a key issue for English learning because vocabularies are fundamental in an English sentence. This study proposes a study system of English vocabulary learning based on theory of depths of processing. The paper chooses 120 freshmen majoring in English, as the participants. Different vocabulary learning methods are employed for comparison. The vocabulary learning method based on theory of depths of processing is proved to be the most effective way for vocabulary learners to enlarge their lexical size and improve their retention rate of vocabulary.
