汉语成语一直被认为是中华文化的精华,是汉语学习过程中不可忽视的一部分。现在学习汉语的越南人越来越多。对越南学生来说,仅会简单说一点汉语是不够的,他们希望了解更多成语,更深层次地了解汉语成语背后的文化,提高汉语运用能力。但由于动物成语的丰富性、结构的稳定性、意义的整体性和语法功能的多样性以及汉语文化背景、风俗习惯的多元性,再加上两国的地理环境及国家的民族思维方式存在差异,两国人民对同一种动物的联想在认知和理解上也存在很多差异。这导致越南学生很难掌握动物成语知识,在应用成语中常常出现偏误。因此,笔者作为越南学生,为了帮助越南学生更深入地学习和理解汉语动物成语,拟研究越南学生在汉语动物成语习得过程中遇到的偏误,归纳偏误类型,分析偏误原因并提出针对性的学习策略。本研究通过深入分析汉语与越南语动物成语的构词特点和文化内涵差异,揭示了语言结构和文化背景理解不足是导致越南学生在学习汉语动物成语时产生偏误的主要原因。通过设计并实施调查问卷,详细分析了越南学生在汉语动物成语学习中的具体偏误类型,包括语义偏误、语法偏误和语用偏误。调查结果显示,这些偏误不仅影响了学生运用语言的准确性,也限制了他们对汉语文化深层次的理解。针对发现的问题,本文提出了相应的对策,旨在帮助越南学生克服学习障碍,深化对汉语动物成语及其背后文化的理解。这些对策包括加强文化背景知识学习、采用成语分类和归纳法,以及通过多样化的学习活动和资源创造丰富的学习环境。研究强调通过多媒体资源、实践互动和中越文化交流活动等手段,激发学生的学习兴趣,提高其汉语成语的实际应用能力。本研究对于汉语作为第二语言的教学实践具有重要意义。通过实施本研究提出的学习对策,不仅可以有效减少越南学生在汉语成语学习中的偏误,还可以促进中越文化的交流与理解,为越南学生提供一条深入学习汉语、提升跨文化交际能力的有效途径。

《汉语》是越南汉语教学的常用教材,出版于2002年。本研究针对越南汉语教材《汉语》中高级阶段的练习题,着重探讨其在提升学生语言水平和实际应用能力方面的效果。考虑到当前对该教材练习题的研究相对不足且缺乏与其他教材的对比,本研究选择了《汉语》教材作为研究对象,并与其他汉语教材进行对比研究,旨在揭示其独特特点和可能存在的不足之处。本文对《汉语》三册教材中的语言知识习题和言语技能习题进行了统计分析,总结了其编排特征。首先,语言知识习题主要集中在句型和语段习题上,词汇习题较少,汉字习题缺乏,反映了中高级阶段的特点,但存在分布不均衡的问题。题型设计新颖,但高频题型有限,语段习题功能性和趣味性不足。其次,言语技能习题的数量分布不均衡,阅读和口语习题比例最高。写作习题题型数量少,影响学生的写作能力发展和学习体验,教学内容缺乏多样性和灵活性。综上所述,教材在题量和题型分布上存在改进空间,需要在设计时予以重视和调整,以提升学生的语言运用能力和教学效果。本文研究了《汉语》教材中的习题内容,重点分析了语音、词汇、句型、语段和文化等方面的特点。语音习题强调声调和语调训练,词汇习题注重词语运用,句型习题培养灵活运用能力,语段习题重视组织结构和逻辑思维,文化习题通过写作和翻译增强跨文化交际能力。研究发现,教材习题设计全面,注重基础知识和综合运用能力,具有实用性和趣味性,涵盖日常生活和文化因素,有助于提升综合语言素养。建议在教学中灵活运用,进行差异化教学。本文对比了《汉语》教材与范杨洲的《汉语教程》在习题形式和习题内容方面的差异,本文得出了结果:在内容方面,《汉语》还存在不足之处:第一,教材缺乏相应的听力理解习题;第二,在口头表达能力方面,分角色对话习题的数量相对较少;第三,在书面表达能力方面,习题形式相对传统,缺乏创新;最后,在文化方面可以进一步扩展和丰富这方面的内容。在习题形式方面,教材充分考虑了学习者的学习阶段和需求,设计了机械性、理解运用性和交际性三类习题。特别是在理解运用性和交际性习题方面,教材设计了丰富多样的题型。在观察与分析过程中,本人还发现了一些不足之处。特别是在《汉语》(10册)教材中,机械性习题和交际性习题的数量明显不足,而理解运用性习题的比重过大。通过对《汉语》使用者进行问卷调查和访谈,本文发现他们对《汉语》教材习题相对满意。尽管如此,他们也提出《汉语》教材习题还存在一些问题:第一,一些课文的主题内容已显得陈旧;第二,需要增加听力和口语习题;第三,在习题中添加插图;最后,尽管他们对文化因素很满意,但他们还建议增加文化因素。综上所述,本研究的结果对于越南《汉语》教材习题的修订和再版,以及未来越南教材习题的编写具有重要的参考价值。通过对《汉语》教材习题的深入分析和评估,并与范杨洲的《汉语教程》进行对比研究,结合师生对《汉语》习题的使用情况、习题编排的满意度和需求,本研究提出了一系列改进建议。这些建议涵盖增加听力习题、加强文化因素的融入、提高习题的趣味性和多样性等方面。尤其需要加强对中高级水平学习者的习题设计和使用分析,以更好地满足他们的学习需求。本文期望这些建议不仅能够协助改进现有教材的质量,也能够为未来教材编写提供借鉴和参考,进一步促进汉语教学质量的提升。
