This platform encourages more and more people from various continents and countries to talk or “type” in English. Thus, the accuracy and proficiency of English command takes on greater and greater importance. It is the very reason why online dictionary appeared and thrived rapidly. Under this situation, I try to make an investigation into the frequency of use of the online dictionary among English major students in junior and senior. The subjects of my research are English major undergraduates in junior and senior who are skillful in English basic skill (listening, speaking, reading, writing and translating.)62378

   Although online dictionary has become an indispensable part of daily life, we have limited knowledge about them. A great amount of people cannot distinguish online dictionary, electronic dictionary and paper dictionary. Many scholars have done a lot of researches on the topic of online dictionary. However, previous researches of online dictionaries are normally from the aspects of advantages and disadvantages of online dictionaries and research subjects are often English major students or non-English major students. This thesis is from the aspects of positive and negative influences of online dictionary. I try to find the influences of online dictionary in advanced English learning.

在线词典在英语专业学生中使用调查及利弊分析

伴随着智能技术的快速发展，互联网成为一个无处不在的交流平台并且极大地促进了人们的工作、学习以及生活的方方面面。互联网平台的发展促使着世界各地的人们用英语进行交流。因此，使用英语的准确性和熟练度显得尤其重要。这也就是为什么在线词典出现以及快速发展的原因。在这样的背景下，我试着做一个在线词典在大三、大四本科生使用情况的调查。我的研究对象是英语专业本科生大三，大四学生——这是一群熟练掌握英语听、说、读、写、译基本功能的学生。

虽然在线词典成为了我们生活中不可或缺的一部分，但是我们依旧对其知之甚少。很多人无法区别在线词典，电子词典以及纸质词典。也有很多学者做了关于在线词典的研究报告。然而，很多先前的研究报告的落脚点往往是在线词典本身的优缺点上。研究对象往往也是英语专业学生或者非英语专业学生。这篇论文的落脚点在于研究在线词典的对应于学习产生的正效应和负效应。笔者尝试研究在线词典在对高级阶段英语学习的一些影响。
