求翻译：母语负迁移的产生主要源于是在第一语言系统即母语已经形成的基础上建立起来的目标语言系统。在第二语言系统的学习中，会下意识参照母语的思维模式和语言习惯，其中也包括对母语里出现的文化语境进行学习。这种情况在中国人学习英语时也是如此，我们国家现在的英语学习开始于小学高年级，此时学生已经能熟练掌握母语语言系统（包括其地方方言），母语发音（甚至是地方方言发音）已经成为一种根深蒂固的习惯，这个时候把他们放在英语的目标语进行学习，他们会很自然地将汉语的发音、结构和功能知识与英语“挂钩”，或者直接把两种语言体系相似之处相互替换，这样对目标语的语音语调学习造成了难度，负迁移的影响也开始显现。是什么意思？
