　　I. Introduction
　　Learning is a complicated process in which every condition and each factor perform their own functions. English learning has its own characteristics and methods in terms of psychology. A small vocabulary is an intractable problem for Chinese students and the only solution is to find excellent approaches under the guidance of which the students can enlarge their vocabulary effectively. Some English learners strengthen their memory continuously， but forget parts of the knowledge they have learned gradually. English words study is connected with forgetting tightly. In this article，， I point out the knowledge of forgetting firstly， and then analyze the causes of forgetting from the psychological aspect， and finally put forward six suggestions accordingly in the only hope that readers can be enlightened.
　　II. Forgetting theory and the causes of forgetting
　　“So many words need remember and I keep forgetting.” We often hear sentences like this. That’s the complaint by the pitiful students. Forgetting is obnoxious！ If we want to gain a large vocabulary， the biggest enemy for us to defeat is forgetting. Forgetting is the opposite course of retention.
　　Many causes of forgetting have been put forward by psychologists. Information， despite being received by the senses， may be forgotten， because it has not reached long term storage for two main reasons： multi-store model information processing limitations and insufficient information processing. The multi-store model can be thought as a set of filtering mechanisms that reduce the vast amount of information received by the senses down to manageable and useful proportions. Thus information not paid attention to in sensory memory will decay， while due to the limited capacity of 7 plus or minus 2 items in the short term memory， any information not rehearsed or passed into long term memory will be displaced by new coming material and will therefore be lost. According to the levels of processing model if information is only processed at a shallow level， then the resulting memory is unlikely to persist for very long and will be forgotten. Material may reach long term memory storage but may then become unavailable either rapidly because it has failed to be consolidated or slowly because that consolidated memory trace fades in strength over time. Forgetting is harmful， so we should try to prevent what we have memorized from forgetting.
