大学英语教学大纲(修订本)规定大学英语教学分为基础阶段(一至二年级)和应用提高阶段(三至四年级)。应用提高阶段的教学包括专业英语(Subject．Based English，简称SBE)和**英语(Advanced English，简称AE)两部分。大纲明确指出：“大学英语教学的目的是培养学生具有较强的阅读能力和一定的听、说、写、译能力，使他们能用英语交流信息。……以适应社会发展和经济建设的需要。”新世纪对人才在外语方面提出了更高的要求。抓好大学英语应用提高阶段的教学已势在必行。编写本教材的目的是帮助理工科学生在应用提高阶段进一步发展、巩固和提高基础阶段已掌握的读、听、写、说、译五种技能，并使部分有一定口语基础的学生在听说能力方面也能有较大的提高，以适应21世纪对**人才的需求。
本教材主要适用于已完成基础阶段学习的高等学校理工科本科生，为应用提高阶段的必修课和选修课教材，也可用作研究生教学或工程技术人员的外语培训教材。
全套教材由专业教师和英语教师合作编写而成。它以英国语言学家H．G．Widdowson的交际法理论为依据，着重解决语言运用能力的培养问题，使学生将基础阶段已掌握的英
