大学英语听力5原文1--5课

大学英语5听力上海外语教育出版社 lesson 1 partA problems facing foreign students Today I'd like to talk about some of the problems that students face when they follow a cource of study through the medium of English--if English is not their mother tongue. The problems can be divided into three broad categories: psychological ,cultural and linguistic. The first two categories mainly affect those who come to study in Britain from Asia and Africa.I'll come to comment only briefy on these two categories and then spend most of the time looking at linguistic difficulties which apply to everyone. some of the common psychological problems really involve fear of unknown: for example,whether one's academic studies will be too difficult.Looking at the cultural problems,we can see that some of them are very practical nature, for example , arranging satisfactory accommodation.Others are less easy to define.

“英语听说课”教学方法

“英语听说课”教学方法交流探讨 现行外研版英语课本的每一单元的第一课安排的都是“听说课”。那么应该怎样上好一节英语听说课呢?首先教学目的要明确,教学目标要具体,突出课型。既是“听说课”,就应该体现听、说两个重要环节。不可以上成语法课或只是讲解其中知识点、做练习。备课时要列出本课要达到的目标及要掌握的语言点、功能及听说技能。 具体的教学步骤: 1.教学新单词。听说课不同于阅读课,它重点在于培养学生的听说技能,所以在真正听说之前要教会学生掌握新单词及一些重要的短语,特别是它们的发音。(此部分也可结合2 “听前活动”一起进行)。 2.听前活动 听前指听前准备阶段。即该阶段师生所进行的活动。其目的是介绍听说语篇的主题,文体或听力的目的,使学生对该语篇有所感知,这样学生就可以有备而听。而且可教学部分重要的新单词、词组。如初二上半学期,以莎老师在教Module4 Unit1时,通过一段与学生的free talk“Who is your good friend?”等问题自然引出like the same thing 和get on well with等短语,在教新单词的同时也对课文内容有所了解。有时我们也可以给出主题,让学生猜测将会听到什么内容。当然,我们也可通过图片、录像、录音、有关话题、引导性的问题等介绍课文有关的文化背景知识或设置与课文有关的情景,引出课文中的生词、句型及内容。 3.听中活动 要求学生不看书听录音磁带,包括泛听和精听。听第一次获取课文中的一般信息。(对话过长的教师可处理为2-3个独立部分);精听阶段要求学生在初步理解语篇基础上进一步理解语篇的细节和重要事实,所以听第二次时应提出一些具体的细节问题,以获取课文中的具体信息。根据学生的不同程度设计的检查学生理解能力的题型有难、易之分,其中包括单项/多项选择题、对错题、搭配题、改错题、问答题等。(有些较难的句子中间可停顿,让学生有思考的时间;开放型问题可逐渐增多)。 4.跟录音带朗读。 5.语言点的讲解。 6.读:其形式包括朗读、默读、对话、角色扮演等。 以上只是我们在英语听说课中的一些不成熟的尝试,希望大家共同交流探讨。

Unit 1 Parents Part B Listening Tasks Passage 1 Dating with My Mother (Part One) Exercise 1 Listen to the recording and choose the right answers to the questions you hear. After 22 years of marriage,I have discovered the secret to keep love alive in my relationship with my wife, Peggy. I started dating with another woman. It was Peggy's idea. One day she said to me, "Life is too short, you need to spend time with the people you love. You probably won't believe me, but I know you love her and I think that if the two of you spend more time together, it will make us closer." The "other" woman my wife was encouraging me to date is my mother, a 72-year-old widow who has lived alone since my father died 20 years ago. Right after his death, I moved 2,500 miles away to California and started my own life and career. When I moved back near my hometown six years ago, I promised myself that I would spend more time with mom. But with the demands of my job and three kids, I never got around to seeing her much beyond family get-togethers and holidays. Mom was surprised and suspicious when I called and suggested the two of us go out to dinner and a movie. "What's wrong?" she asked. "I thought it would be nice to spend some time with you," I said. "Just the two of us." "I would like that a lot," she said. When I pulled into her driveway, she was waiting by the door

大学英语听力教学心得

大学英语听力教学心得 庞静 相对于其他正规院校的本科生来说,高职生的英语基础较差,平均水平不高。从英语听力课的教学来看,其不足主要表现为词汇量少,语音语感较差,知识面窄,独立进行分析判断能力不足,从而反应较慢。除此之外,高职生在英语听力学习方面的不足还表现为缺乏良好的英语听力的自我控制能力和逻辑思维能力,缺乏良好的听力习惯,缺乏应有的自学能力,这一切都无形中构成了高职生英语听力学习的障碍。在我上的大学英语听力的部分系部表现的特别明显。教材是教学的依据,教材的选用和利用对于教学来讲意义重大。虽说我们学校的大学英语听力选用了不同的教材——外语系选用的大学英语听力;人文系选用的英语教程;音乐美术系选用的实用英语。但由于系部不同班级的学生水平也参差不齐,所以因材施教显得尤为重要。 外语系学生相对英语成绩相对较好,大部分学生的学习积极性都比较高。处在这个竞争愈来愈激烈的社会中,他们强烈地感受到自身的不足,从而有着很高的学习积极性。但同时也有相当一部分同学由于种种原因或自卑不前,或自满松懈,或心不在焉,学习态度和学习成绩均和前者有着很大差距,形成两极分化。外语系选用的教材中每个单元由三部分组成:第一部分通常是语音练习,它对于纠正学生的发音很有帮助。教师在完成这一部分的听力练习之后可以接着让学生跟读,模仿,从单词到长句,循序渐进。同时讲解相应的发音规则。第二部分通常是对话和短文。由于部分学生基础较差,如果按照机械的程序从讲解词汇,介绍背景,播放录音直至完成练习,他们会感到十分吃力。于是我一般在讲完词汇和介绍完背景之后,先把所要播放的录音内容概述一下,当然语速要慢。这样可以给学生留下一定的适应时间,帮助他们理解接下来的内容。第三部分是口头练习,这一部分往往会被忽略,我认为这是十分可惜的。不妨让学生根据所听的内容编排对话,复述大意或进行主题讨论,将听与说结合,把听到的内容用自己的语言表达出来。语言是交流的工具,而交流则包涵了由听到说的过程。听是说的基础,听最终要服务于说。 人文系现在的英语教程听力没个单元有不同的话题,围绕这个话题从report 来引出话题,这部分比较简单。然后10个段对话,1个长对话,1个短文听力。这部分听完,再简单讲解一下基本上要花一节课的时间。对于学生的认知,45分钟都在不停的听,做题目无疑会走神,事倍功半,往往是开始20分钟效率特别高,然后就思想松散了听的有一句没一句的。休息5分钟后按照课本内容是听电影片段做填词。这部分联系简单但由于是原声电影说话的语速很快而且连读,省略都很多,加之听力疲劳。所以效果也不佳。我觉得还是听与说要结合交替进
