17、是我们如何用心、用脑、用手去做。 我国基础教育课程改革的趋势之一是加强课程与学生生活和现实社会的联系。 本次课程改革的内容强调联系生活、 社会、 学生实际， 在方法上强调探索、实践、活动，实现课程生活化、社会化和实用化，但这并不是让课程脱离学术轨道， 而是让课程和学生生活和现实社会更有效地融合起来，给已有充分发展的学术课程增添时代的源泉和生活的活力。我们有理由相信：怎样有效的把课堂与生活紧密联系在一起，化课堂为生活，融生活于课堂，是一个值得我们老师好好利用却时时困扰我们的话题。只要我们做有心人，充分挖掘生活中的可利用资源。相信孩子们在学习中会获得乐趣，在游戏中获得知识，在课堂中除了学到语言，更多的是学会用语言的方法。真正使英语贴近生活，运用于生活，服务于生活。
