点评：
范文首段指出，有关电子辞典的讨论从来没有停止过;第二段阐述优点，即电子辞典便于查询，而且随着技术的发展，电子辞典功能也越来越多，另外价钱也越来越低;第三段提出缺点，电子辞典让学生产生依赖心理，而且有些解释不准确，另外技术的进步不一定带来学习上的进步;最后一段总结，电子辞典本身无对错，关键在于正确使用以便为我们服务。
第二段第三句中的illustrate表示用图或例子来说明第三点中的afford表示买得起。第三段第一点中的relytoomuchon表示过分依赖putonesheartintodoingsth.表示专心致志于某事第二点中的accurate表示精确的，misleading表示使人误解的第三点第二句中的decisivefactor表示决定因素。
