由于我们每个人头脑中的观念和想法主要是由我们的母语来构建的,一个语言学习者的母语对中介语有着很大的影响。这些影响可能是积极的,也有可能是消极的。有时候,一个语言学习者的母语会让二语的学习变得简单,甚至是促进二语的学习。但是,语言学习者在学习的过程中遇到的很多困难,诸如在目标语言的语音、词汇以及语法上遇到的困惑是由于母语的影响造成的。 Since the concepts and ideas in each of us minds are mainly constructed in our native language, the mother tongue of a language learner has a great influence on the interlanguage. These effects may be positive or negative. Sometimes, the native language of a language learner makes the learning of a second language easier and even promotes second language learning. However, many difficulties faced by language learners in their studies, such as the confusion in the pronunciation, vocabulary and grammar of the target language, are caused by the influence of their mother tongue.
