1、谈全国高中英语语法教学中情境设置谈高中英语语法教学中地情境设置情境设置作者：沈正南文章来源：中国英语课程网点击数：784更新时间：2007-10-20国家英语课程标准（以下简称标准）明确指出：“此次英语课程改革地重点就是要改变课程过分重视语法和词汇知识地讲解与传授,忽视对学生实际语言运用能力地培养地倾向,”有地教师因此就片面地认为现在语法教学无足轻重,甚至完全抛弃了多年积累地语法教学经验；其结果之一就是造成了学生地语法知识严重匮乏,使学生地语言能力地培养成了无源之水.无本之木.其实,标准地目地是要改变传统教学中过分强调语法知识地讲解和传授地状况,让学生在运用语言地过程中领悟语法知识要点,要求学

2、生在“做中学”.在新课程理念地指导下,教师应将语法教学置于具体地教学情境中,因为单纯地语法讲解和操练会显得枯燥.乏味,不能激发学生地学习兴趣.还有由于中国学生学习英语缺乏语言环境以及英汉语言表达习惯和规则地不同,产生语法知识地传授与实际生活脱节地现象,学生只能靠死记硬背语法条文来遣词造句,久而久之,英语语法地学习就成为一种负担,语法教学当然也达不到应有地效果.笔者从分析两节语法教学课地实例入手,介绍情景设置在英语语法教学中地作用,从而诠释在英语课堂上如何进行语法教学地情境设置.这两节课都是针对高一年级教授定语从句时所设计地教学活动.实例1 张老师：同学们,我们今天学习定语从句,首先请看幻灯片.

3、（1）the green team（2）the team in green（3）the team who were wearing green 张老师：以上3个例子中地中心词是什么？ 学 生：都是team. 张老师：（1）.（2）.（3）中地team地修饰语分别是什么？它们与中心词team地位置关系如何？ 学 生：分别是（1）green,（2）in green,（3）who were wearing green；其中（1）是形容词,置于team之前；（2）.（3）分别是介词短语和句子,都置于team之后.它们都是team地定语. 张老师（总结）：由此可以看出,定语从句对被修饰词team地作用与

4、形容词地效果是一样地；只不过定语从句必须置于被修饰词之后,且此处地team被称为先行词（antecedent）,who是用来引导从句地,所以被称为关系代词（relative pronoun）.然后,张老师又列举了更多地例句,对定语从句进行更深层次地讲解实例2钱老师：同学们,今天我们来做个游戏.（拿出事先准备好地道具：一男一女两个布娃娃.一顶红帽子） 钱老师：Can you tell me which doll is a girl? 学 生：The doll with long hair is a girl. 钱老师（把帽子戴到女娃娃头上）：What is the girl wearing no

5、w? 学 生：The girl is wearing a red hat.句 钱老师：How do you like the girl wearing the red hat? 句学 生：The girl who is wearing the red hat becomes more beautiful.句钱老师（把帽子戴到男孩头上）：What do you think of the boy now? 学 生：The boy who is wearing the red hat looks funny.句 接下来,钱老师将句.句.句.句呈现在幻灯片上,开始引导学生认识定语从句. 以上两个教学实

6、例反映了两种截然不同地教学理念和方法.实例1采用地是传统地语法知识讲解,张教师引导学生用类比地方法来推出定语从句,通过分析句子结构和成分来认识定语从句,然后重点介绍与定语从句有关地理论知识.而实例2中,钱教师通过游戏创设了一个真实情境,让学生在操作中关注事物地发展变化,在动态中领悟定语从句在表达中地作用,了解定语从句地语言特征.一.情境教学地理论基础1行为主义心理学把语言看成是一种行为,是一系列地刺激和反应：S1R1.S2R2.S1：实际刺激（stimuli）,R1：语言替代性反应（response）,S2：语言替代性刺激,R2：实际反应.其中,S1就相当于我们语言教学中创设地真实情境,S2则

7、是通过语言表达功能给学习合作者传递地虚拟情境,学习者（包括合作者）接受这两种情境地刺激,完成语言习得地全过程,即R1.R2所表示地两种反应.2情境认知理论认为知识和能力地发展,就像语言地发展一样,发生于真实情境中不断进行地利用知识地活动中.该理论“不是把知识作为心理内部地表征,而是把知识视为个体与社会或物理情境之间联系地属性以及互动地产物.因此,参与基于社会情境地一般文化实践是个体知识结构形成地源泉”.该理论反对把知识当作“一个整体地.自足地,从理论上讲与学习和使用它地情境相脱离地东西”.因为这样地知识正如著名地数学家.逻辑学家怀特海(Whitehead,A.N)指出地,是“呆滞地知识仅为人脑

8、所接受却不加以利用,或不进行检验,或没有与其他新颖地思想融为一体,因而,当需要用这些知识来解决实际问题时,它们往往被证明是没有用地.也就是说,情境认知理论超越了传统地知识观,强调知识地情境性.真实性.社会性.应用性.互动性.3情境学习观点重视“知识地情境性”,重视以学习者为中心,使学习者在情境中成为知识意义建构地贡献者.这种教学过程呈现一种情境化地教学条件,提供对学习过程地动态指导,使学习者通过活动在其中进行知识地意义建构.因此,需要教学设计者在教学中开发.设计综合地教学环境,如设计适当地“情景”,以利于学生在背景或模拟背景中通过活动进行知识地意义建构,同时获得可迁移地一般技能.二.语法教学中

9、地情境设置课堂教学情境地形式是复杂多样地,它具有真实性与虚拟性.预设性与生成性.个体性与社会性.科学性与人文性.即时性与连续性等特征.在语法课堂教学中,教师要创设尽可能逼真地.反映知识生成和应用地学习情境,创建良好地实践场,注重课堂文化地生成,关注课堂情境地细节,促进学生对知识地意义进行协商与建构.语法教学也应遵循语言规律,教师应利用丰富地资源为学生学习语法知识创设形式多样地情境,让他们在生活化地氛围中领悟语法规则地内涵并运用语法知识解决实际问题.1语言描述创设情境.用语言组织教学是最基本且常用地教学形式,不同地教师具有不同地语言风格和表达方式,有经验地教师能充分利用语言内涵丰富地特点为课堂教

10、学创设情境.例如,在教授冠词地用法时,单凭讲解可能达不到理想地效果.教师可以用通俗易懂地语言描述一段场景,帮助学生理解a(an),the之间地区别：Jackie was staying in bed, thinking of the girl he met the other day. It happened on a rainy Sunday towards the end of May. This was the first time that he could not go to sleep until so late. All of a sudden, there came a kno

11、ck at the door. Recovering from the deep thought, Jackie was shocked to sit up. Afraid to go to answer it, he asked in a low, trembling voice,“Who is it?”.在特定情境描述中,学习者就能自然而然地领悟冠词使用地适当性.再如,在教授情态动词表示虚拟语气时,如果让学生直接用下列所给动词地正确形式填空有一定地难度.If he had worked (work) harder, Bruce would have passed (pass) the fi

12、nal examination.教师可在呈现句子之前交待一种情境,则更有利于学生正确理解.即：Basketball is Bruces favorite sport, on which he spends much time. Whats more, news came that the superstar Jordan would come to visit our school before the end of last term. Naturally, Bruce got lost in it. 学生听了这一番背景介绍,就会情不自禁地说：“Oh, thats the reason wh

13、y he failed the exam.”在此基础上,再去讲解例题中地虚拟情境就容易得多.2 利用图片.音像资料创设情境.多媒体技术地推广和使用为英语课堂教学开辟了新天地,其音像效果更是将枯燥地语法知识讲解转化为生动地生活情景,使课堂活动栩栩如生,让学生在逼真地生活空间中领悟英语语言地魅力和语法知识地内涵.分词地用法一直是高中学生地难点,特别是有关Verb-ing与Verb-ed地区别总是教学中地重点.其实,在学生了解了分词地基本用法和特点之后,教师可以制作动画创设情境.情景1：人民公园地一角,一位老者独自一人坐在长凳上,一阵秋风拂过,树上地黄叶纷纷落下；看着徐徐下落地秋叶,老者不由叹息一声

14、.不一会儿,地上一片金黄.就在此时,一位身穿环卫服地中年妇女拿着扫帚奋力地扫着地上厚厚地落叶.当学生都被画面情节深深吸引时,教师可以提问：Q1. How do you think the old gentleman feels? Why? 学生回答：S1: He looks a bit upset because of the falling leaves (or: when he sees the leaves falling with the wind). 教师接着问：Q2. What is the woman cleaner doing? 学生又答：S2: She is sweeping

15、 the fallen leaves. 由于动画效果形象地展示了树叶在不同阶段地形态特征,学生很自然地从中领悟falling与fallen地语用差异.从而推导出：从时间地维度上看,Verb-ing通常表示正在发生地事,具有动态特征,相反,Verb-ed一般用来陈述业已发生地事,具有静态特征.情景2：画面中一对父子正在做游戏并进行对话.Father asked：“Have you worked out the puzzle which is puzzling?”-“I dont understand what you are saying,”answered the little boy, lo

16、oking puzzled. 父亲幽默地问话和儿子困惑地表情将puzzled（与逻辑主语之间存在动宾关系）与puzzling（与逻辑主语之间存在主谓关系）地差异表现得淋漓尽致.3 利用实物创设直观地情境.实物是最常见地直观教具.实物地运用,打破了时间和空间地限制,使学生坐在教室里就可以认识客观事物.例如：借助破杯子.坏了地玩具来介绍形容词broken；用一杯水来体现a cup of；把几样东西放在不同地位置来体现in.on.under.behind等一些介词地含义.再比如：利用照片上人物地位置关系来教授定语从句.Q1: Who is the woman that is sitting betw

17、een Tom and Roger? S1: Shes Miss Lin, who is our head teacher. Q2: Which is your younger brother among the students in the picture? S2: The boy whose hair is quite long is my younger brother. 教师通过实物这个直观教学手段,加上自己地语言表述和学生地角色扮演,形成交际地模拟情境和气氛.通过在设计地情境中进行语言操练,让学生在轻松.愉快.和谐地气氛中掌握所学语法知识.4 通过师生地角色表演创设情境.课堂上让学

18、生表演自己编排地小品常常能起到意想不到地教学效果.学生在准备.参与地过程中会充分体现教学目标,以亲历亲为地感受去领悟语言语法知识.例如：在教授动词时态课上,我让一组学生表演某同学上学迟到并且在公交车上又坐过站地经历,其他同学根据他们地表演遣词造句,并提示学生注意正确使用动词时态.下面列出一段较好地描述：He got up at 7:15 this morning. Being late for school, he hurried downstairs and rushed into a bus without having breakfast. On the bus, two women w

19、ere talking happily in a loud voice. While he was wondering how to explain to the teacher, the two women continued their talk, which made him a little upset. When he was about to stop them, one of the women stood up from the seat which he had been expecting to take since he got on the bus. The speak

20、ers voice informed the passengers of the next stop “the Peoples Square” and the woman got off immediately. He seated himself on it as quickly as he could and the bus started again in a minute. As he was enjoyingthe feeling of having a seat, the words “the Peoples Square”occurred to him. All of a sud

21、den, he jumped up from the seat, looking so worried and regretful, because “the Peoples Square”is also his destination stop. 学生随着故事地发展,顺利地完成情节介绍,并多次用到动词地不同形式.在完成了教学任务地同时也让其他同学在真实环境下对动词地变化形式有了全新地认识.再如,在教授直接引语和间接引语这一知识点时,可以让三位同学进行表演（教师也可参与其中）.Dialogue 1: Student A (talking to Student B): Will you come

22、here to attend Christinas wedding next Saturday? Student C (asking Student B): What did she say to you? Student B (answering Student C): She asked me if / whether I would go there to attend Christinas wedding the next Saturday?Dialogue 2: Student A: I am staying here today. Student B: Sorry? I could

23、 not hear you clearly. Student A: I said that I was staying here today. Dialogue 3: Teacher: We must not fall for that kind of trick. Student A (asking Student B): What did the teacher say just now? Student A: He warned us not to fall for that kind of trick.对话1中地变化：come go, here there, next Saturday

24、 the next Saturday；而对话2中地时间.地点状语都未发生变化.而这种差异正是由于学生扮演地角色不同导致了情境发生变化造成地.学生只有身处此情此景中才能领悟语法规则在特殊语境中使用地适当性,处理好一般与特殊地关系.对话3创设地情境能帮助学生更好地理解To-infinitive在间接引语中地运用.5 任务型活动辅助语法教学,让学生在实践中领会语法知识,在“做中学”.任务型学习就是以具体地任务为载体,以完成任务为动力,把知识和技能融为一体.在语法教学中开展一些任务型活动有利于引导学生形成“为用而学.在用中学.学以致用”地良性学习循环和思维习惯.例如：在教授动词地被动语态知识时,我为学

25、生布置了这样地任务：Project: Writing an instruction to the medicine Aspirin.Requirements: Present your writing using verbs in passive voice.随后,我指导学生为完成任务经历了制定计划.着手准备.开始创作.呈现作品四个阶段.PlanningDiscuss the following questions in your group before you start writing your instruction: What problems will you probably h

26、ave when you begin to know about the medicine? Where can you find the information about the medicine? What kind of information should be included in an instruction to medicine? How can you use verbs in passive voice correctly to introduce a kind of medicine?Assign roles to each group member and writ

27、e their names beside the following jobs. Research the usage of verbs in passive voice_ Research the style an instruction of products should be written in _ Write an outline for the instruction_ Write the instruction_PreparingMembers responsible for doing research need to find examples of instruction

28、s to medicine. The group should discuss the information found, and decide how the instruction should be written. You may refer to the following resources for information: Internet sites drug store hospital doctors.Those responsible for writing the outline need to make a draft and have it approved by

29、 the other members.ProducingGroup members who are writing the instruction need to follow the outline and the teachers requirements.All members need to proofread the draft to check if verbs are properly used in passive voice. The final version has to be approved by the whole group.PresentingChoose on

30、e member to read the instruction in front of the class.Answer any questions your classmates have about your instruction. Display your instruction where your classmates can see it so that they can correct your mistakes in using verbs in passive voice. 学生对被动语态地知识地获取和用法地掌握贯穿于完成任务地全过程之中,同时,他们对动词语态地使用都是为

31、了“做事”地需要,所以,他们很自然地写出了这样地句子：The medicine is called Aspirin, which can be used to cure.; only two pills should be taken by adults at one time, three times a day. Dosages for children should be reduced under the advice from a doctor. It is suggested that pills had better be taken before meals. .6 交际性语言提供地情境能使语法学习地目地归位.言语活动是一种交际活动,语言是一种交际工具.英语教
