选项
答案 The past decade has witnessed a boom in Internet-based instruction both at home and abroad. Online education with or without record of formal schooling is readily available. The attraction of the fenceless school for students is obvious. Learners can cast aside the restriction of age, profession or educational background and select freely according to their own need the studying contents. Additionally, with the instructors posting syllabi, reading assignments, and schedules on Websites, and students sending in their assignments online, time and space are no obstacles to anyone. Meanwhile, expenses and resources are accordingly saved for both students and schools. Obviously, webucation broadens the channel of knowledge reception, realizes learner-centered auto-study and enhances the learners’ ability of knowledge acquisition and knowledge updating. As for me, to enhance integrated quality by selecting some popular web courses annually will be a long-term mission.
解析     这是一篇重点在于分析某现象的原因的文章。
    第一段用两句话简单说明了过去十年里国内外网络化学习发展迅速这一现象。亮点词汇decade “十年”，比用ten years显得有水平；witnessed“见证”，以时间地点作主语，事件作宾语，表示在某个时间或者地点发生了某事，属于拟人化的用法；boom“蓬勃发展”；(at) home and abroad“国内外”。Internet-based, instruction和Online education是“网络教育”的两种不同表达，体现了用词的多样性。
    第二段分析这一现象的原因。第一句是承上启下的过渡句。第二句详细说明了第一条原因：学习者可以不受年龄、职业、教育背景等的限制，自由选择课程。随后一句用Additionally引出了第二条原因：由于教学活动都在网上进行，师生都不受时空限制。紧接着用Meanwhile引出了第三条原因：费用和资源得到节省。最后用Obviously进行升华、小结：网络教育拓宽了接受教育的渠道、实现了以学生为中心的自主学习、提高了学习者获取知识和更新知识的能力。这一段中的the fenceless school 和webucation又是“网络教育”的另外两种表达。其他亮点词汇还有：cast aside, obstacles, accordingly, broadens the channel, learner-centered, enhances the ability, knowledge acquisition, knowledge updating等。
    第三段简明扼要地说明自己的打算：每年选几门受欢迎的网络课程来提高自己的综合素质。亮点词汇有：enhance, integrated, annually, long-term mission。
