摘　　要：计算机辅助考试系统在英语考试中占有重要的地位。开发人员在对当前计算机辅助英语系统现状调研和分析的基础上,针对系统跨平台及考生对考试系统人机交互性的需求,设计和开发了基于Qt计算机辅助系统考试作答子系统。详细描述了系统的设计和实现,介绍了系统的通信设计方案、音频处理方案以及界面美化和提升人机交互效果的实现方法,特别是在试题的显示、交互形式的多样化上做了较为深入的研究,为计算机英语辅助考试系统的考试作答进行了新的尝试。Computer-assisted examination system plays an important role in English examination. On the basis of survey and analysis on existing computer-assisted English system, and according to the cross-platform of the systems and the requirements of examinees in human- computer interaction of examination system, the developer designs and develops an answering sub-system which is based on Qt computerassisted system. The dissertation describes in detail the design and implementation of the system. At the same time it introduces the system communication designing pattern, the audio processing scheme and the method of optimising the interface and human-computer interaction. Particularly, the paper puts intensive focus on the display of test questions and the diversity of interactive models, which makes a new attempt on answering the questions in the system of computer-assisted examination.
