It is well known that the vocabulary of English word is very large, so if learners just recite every word independently, they cannot keep their memory long. In order to keep the memory of word effectively and firmly, one should grasp the basic word-building elements, and then recite the word systemically and relationally according to its relationship with other words and its own pronunciation, form and meaning. It is also necessary to grasp the rule of the words' change and transform in every aspects, turn rote reciting into comprehension reciting, singleness reciting into colony reciting, stiffness reciting into agility reciting.
英语词汇数量之多是众所周知的,而彼此孤立的词是难保持长期记忆的,所以要更有效地、更牢固地记忆单词,只有抓住其基本构词成分,根据每个词的音,形,义及其与其他词之间的诸多联系进行有系统地、有联系地记忆,掌握英语词汇在各方面变化和转化的规律,化机械记忆为理解记忆,化单个记忆为群体记忆,化呆板记忆为灵活记忆。
