30、除。Fossilizationn It refers to the phenomenon in which second language learners often stop learning even though they might be far short of native-like competence.The term is also used for specific linguistic structures that remain incorrect for lengthy periods of time in spite of plentiful input(e.g.

37、ruction SVO is easily understood and positively transferred into Enlish. Positive transfer is termed as fascilitation and facilitates learning. 1. 我我 学学 英语英语 (S+V+O) 2. I study English (S+V+O) It is exceedingly important to remember that the native language of a second language learner is often posi

38、tively transferred. Chinese students of English can easily understand the meaning and constrction of the English sentence and make the positive transfer because the Chinese sentence is the same in structure as the English one.Language TransferPage 34本文档所提供的信息仅供参考之用，不能作为科学依据，请勿模仿。文档如有不当之处，请联系本人或网站删除。
