新教材语法教学交际化是每位英语教师所向往和追求的目标。但是，迄今为止，只有少数教师跨入这个神圣的殿堂，使学生的语法知识在能力训练中得以内化，流畅输出。语法教学要改变过去“满堂灌”的现象，关键在于教师应具有语法教学交际化的意识和技巧。现以湖州一中副校长李冬梅老师去年在丽水地区松阳县执教的初二（下）册第 28 单元第110课语法教学为例，简述如下。
一、从学生生活实际出发，激活元认知。
课堂教学中，特别是语法教学中，教师要注意激活（activate）学生的元认知（meta－knowledge）， 通过日常对话，谈论学生最感兴趣的话题，将学生的原有知识活跃出来，使其具有粘合新知识、构成新认知结构的活力。话题必须从学生生活实际出发，教师循循引导，积极鼓励，多加表扬，拉近师生距离，形成一种浓浓的学习英语的氛围。
二、从已学知识着手，找到最近粘合点。
同样，在语法教学中，教师不要直奔主题，急于求成。相反，应从学生已学过的语法能力着手寻找最近的粘合点。这个过程是师生双方交际的过程，是学生对以往具有的语法能力输出的过程，也是学生为填补教师（或学生）所提问题中所含信息沟的过程，也为新语法能力的培养铺平道路。
三、在学生语言输出中，加深对语法意识的体验。
在语法教学中，教师不应将注意力集中在语法规则或用法上；而应将注意力放在学生对新语法意识成功的体验上。其途径并非体现在教师对该语法项目滔滔不绝或绘声绘色的讲解，而是表现在学生对教师有针对性的语法情景设计（具体以问题形式出现）能作有意义的语言反应上。这种有意义的语言反应，因为有该语法概念作为内核，因此可以使学生的语法意识（不是语法知识）得到体验。这种精心设计的问题越多，学生语法意识（awarenss）的成功体验便越深刻。等到这种成功的体验积累到一定数量时，教师或优秀学生对语法规则或用法（usage ）上的稍加点拨便会使这种体验升华到理性高度，深层地储存在大脑的记忆库中。
至此，语法知识与语法技能已合二为一。但是，问题尚未到此结束，语法能力还未形成。
四、站在语篇层面上，达到自动化输出的境地。
语法能力的培养不能满足于单句训练，那只是语法技能的即席反应，我们还须将语法技能放在一个陌生的语境中加以运用，进一步得到体验。具体地说，即将该语法技能放在语篇中的诸多语法群中加以选择，流畅输出，得以证实。如教师可以设计一个话题，让学生运用所学语法技能，或对课文中某一情景要求学生加以描述。这时候，新学的语法技能融合到众多已学到的语法能力中去并成为其要素之一。如此循环往复，使语法知识、技能和能力螺旋上升，达到自动化的境地。
下面是这堂课的教案和我们的粗略点评。
Teaching Plan for Lesson 110,Unit28(JEFC2B)

点评：
（1）从学生身边之事切入，贴切自然。 在听说和交际中复习和学习了may,can,could,have to,must,mustn't,need 等情态动词，旧中有新，新中有旧，衔接自然，环环紧扣，一气呵成。
（2）设计的话题切合学生实际，使学生讲得出东西。 老师一步步引导，学生用英语讲出了许多好的句子，初步开启了学生的思维之门。
（3）语法知识在大量的口头训练以后加以点拨、归纳，恰到好处。
（4）操练先简后繁、先易后难，有一个铺垫和梯度。
（5）语法知识在交际中运用和提高，使课堂教学出现了高潮。
（6）转折多么自然！ 由于在前面的操练中这道题基本上都在口头练过了，所以学生做起来很容易。
（7）从口头落实到笔头是书面表达能力培养的最佳方法！
