三年的学习生活即将结束，回顾三年的学习生活，感受颇深，收获丰厚。在论文的写作过程中，有很多困难，无论是在理论学习阶段，还是在论文的选题、资料查四询、开题、研究和撰写的每一个环节，无不得到导师的悉心指导和帮助。借此机会我向导师表示衷心的感谢!同时，我要感谢陕西职业技术学院授课的各位老师，正是由于他们的传道、授业、解惑，让我学到了专业知识，并从他们身上学到了如何求知治学、如何为人处事。
同时我也要感谢我的同学给予我的帮助，他们为我撰写论文提供了不少建议和帮助。我要感谢，非常感谢我的导师韩莹老师。他为人随和热情，治学严谨细心。在闲聊中他总是能像知心朋友一样鼓励你，在论文的写作和措辞等方面她也总会以“专业标准”严格要求你，从选题、定题开始，一直到最后论文的反复修改、润色，韩老师始终认真负责地给予我深刻而细致地指导，帮助我开拓研究思路，精心点拨、热忱鼓励。
