    四级辅导讲座听力第一页,讲稿共四十五页哦复合式听写之题型分析复合式听写之题型分析 1.官方公告上明确指出,原复合式听写调整为单词及词组听写单词及词组听写,短文长度及难度不变。要求考生在听懂短文的基础上,用所听到的原文填写空缺的单词或词组共10题。短文播放三遍播放三遍。但客观地说,单从出题形式上讲,改革之后的题型的确比之前的句子在难度上有所降低难度上有所降低。但不代表大家可以轻视,因为越是看似简越是看似简单的题目越容易丢分单的题目越容易丢分。第二页,讲稿共四十五页哦 2.改革后的听写题型较像目前国内的两大口译考试的笔试部分,一是上海市中高口,二是人事部三口。这两个考试含金量都不低,故四六级的改革初衷可见一斑。3.说它难度降低了,不是因为单词短语比长句子听起来简单(貌似简单,实易丢分貌似简单,实易丢分),主要是因为文章仍然读三遍,再难的东西只要能听三遍都不是什么大事了,前提是单词关过了单词关过了。第三页,讲稿共四十五页哦 4.如果像口译考试一样只读一遍,考生不仅要具备坚实的单词和短语基础,还要有扎实的短时记忆能力和速记能力。而四六级只需要有较为扎实的词汇功底扎实的词汇功底。这些能力主要体现在:单词的掌握,不仅是看了认识的视觉词汇,更包括听后听后能迅速反应出来的听觉词汇能力能迅速反应出来的听觉词汇能力以及快快速记下并将所听单词拼写正确的能力速记下并将所听单词拼写正确的能力。否则,在考场上听不出来或是下笔忘词的感受恐怕很让人心烦。第四页,讲稿共四十五页哦新东方备考建议:新东方备考建议:1.单词是硬道理单词是硬道理,用什么记忆方法不是重点,关键是在短时间内快速的多次重复记忆,而且记忆单词的时间也不宜过长,2-3月为宜。2.在四六级考试的大纲词汇范围内,重点记忆名词、动词、形容词名词、动词、形容词,以及大纲上与真题中反复出现的高频词和重点短语高频词和重点短语。记忆单词和短语时要看、读、听看、读、听三者结合,遇到长难单词和真题中反复出现的常考词汇和短语,更要习惯在纸上动笔写一写在纸上动笔写一写。第五页,讲稿共四十五页哦 3.最后词汇的应用当然不能指望单词书上的例句,而是真题真题。通过反复做真题反复做真题,揣摩出题思路、体会词语的实际用法,通过做题加深记忆印象。而听的时候,同音词、近音词、单复数、过去分词同音词、近音词、单复数、过去分词在听的时候都会是一个不小的挑战,因为这将涉及到语音的问题。所以有时间弹性的同学不妨每天花点时间(20分钟亦可)通过跟读和模仿标准的语音材料跟读和模仿标准的语音材料来提高自己的语音水平,并且每周至少抽出3-4天时间,每天30分钟坚定地进行听写练习进行听写练习,这样一来,前后不用半年,你的听力实力将足够你去应对任意一个听力考试。第六页,讲稿共四十五页哦英语四级听力备考误区英语四级听力备考误区 原因一:原因一:泛听多、精听少泛听多、精听少 有的同学每天听得那叫个天昏地暗,上哪都放着听力,走路听,吃饭听,睡觉听,看似非常努力,但是效果却不理想。要在有限的时间内提高听力,多精听少泛听更好。因为四六级考试40多分钟的听力需要你集集中注意力精听,在限定的时间内听懂内容选择出中注意力精听,在限定的时间内听懂内容选择出答案答案。平时越习惯泛听的同学可能在考场上越会遇到走神,注意力涣散的问题。建议同学们每天早上每天早上抽出一个时间段,抽出一个时间段,40分钟到一个小时即可,安静地分钟到一个小时即可,安静地坐着,练习听力坐着,练习听力。远比每天带着耳机,貌合神离的效果好。第七页,讲稿共四十五页哦 原因二:原因二:只动耳、不动手只动耳、不动手 很多考生反映,平时练习听力的时候感觉还行,考试就写不出正确答案,或者老师讲授的方法都明白,做题时却无从下手。这其实是备考听力时一个致命的误区导致的,只动耳不动手。要知道听力考查的一个重要方面是瞬间记忆和速记的能力瞬间记忆和速记的能力,所听所想最终要落实到卷上的答案。这种能力主要就是体现在耳朵到手写的转化过程中,试问你只听不看题不写,中间省略掉这么大的过程,怎么能提高四六级的听力分数呢?四六级听力是应试考试,做题技巧很重要,老师讲授的方法只是启发,唯有在亲自动亲自动手练习手练习中才能慢慢摸索和积累。第八页,讲稿共四十五页哦 原因三:原因三:无的放矢,头痛医脚无的放矢,头痛医脚 相对于阅读等类型的题,听力考查的语言能力更为全面。词汇的拼写,读音,语法,材料的理解和记忆能词汇的拼写,读音,语法,材料的理解和记忆能力力等都有包含。很多同学听不懂再听,听不懂再听,最后还是有很多地方听不懂,所谓一鼓作气再而衰三而竭,信心倍受打击。其实这时候应该停下来,看看自己听不懂究竟是在哪一块上出了问题。比如是不是单词的读音,句子的语调,或者是是不是单词的读音,句子的语调,或者是连读弱读爆破音等原因影响了连读弱读爆破音等原因影响了?明确问题后,有的放有的放矢的进行突破矢的进行突破。如果是语音语调上的问题,多朗读而不是花时间在单词拼写上,一定要找出自己真正的问题,切忌陷入头痛医脚的误区。第九页,讲稿共四十五页哦 原因四:原因四:娱乐至上娱乐至上 一些同学备考四六级听力的常态是音乐与电影齐飞音乐与电影齐飞,娱乐学习两不误,娱乐学习两不误。听英文歌曲和电影对白对听力提高肯定有帮助,但是过程太慢,尤其是四六级。很多同学到最后就只剩娱乐只剩娱乐了,因为我们很容易就被歌曲美妙的调子和电影扣人的情节给吸引去了,而忘记了练习听力的初衷,看过几百部英文电影的看过几百部英文电影的人听力不一定多好人听力不一定多好。而且歌曲和电影可能出现很多口语俚语的表达,对四六级来说帮助不是很大。所以建议同学们先把娱乐放一放,踏踏实实的做些有用的听力练习。第十页,讲稿共四十五页哦英语四级听力三大绝技英语四级听力三大绝技 综合来说,四六级听力从技巧上,只考三项:1.视听一致视听一致(长对话和短文听力的中低难度题目)2.同义替换同义替换(对话和短文听力的剩余题目)3.听写听写(复合式听写)第十一页,讲稿共四十五页哦 题目序号:11-18 及格数量:5-6道 推荐准确数量:6-7题 重点主题:Campus life;job-hunting 重点场景:Restaurant;hotel 核心技巧:1.后句比前句重要,回答比提问重要2.若选项中个别单词或短语被明显播读,此项多为错项;同义词替换选项正确可能性大。3.同义词替换(最保险考点)4.关注对话潜在规则:例如东西断货、房间爆满、考试失败、课程作业抱怨、交通工具迟到、邀约失败.第十二页,讲稿共四十五页哦例一:2010年12月 原文:M:Hows the new job going?W:Well,Im learning a lot of new things,but I wish the director would give me some feedback。Q:What does the woman want to know?A)her new responsibilities in the companyB)what her job prospects(前景)areC)what the customers feedback isD)the directors opinion of her workKEY:D 本题中,第二句为考点,feedback 直接换成答案的opinion,而C项的feedback是明显干扰。第十三页,讲稿共四十五页哦例二:2009年12月第16题原文:W:Ive been working out the gym since January.I was a bit out of shape.M:You look terrific.It seems that your effort has paid off.(你看起来棒极了,看来努力没有白费.)Q:What does the man imply about the woman?She must have paid a lot for the gym.B)She is known to have a terrific figure.C)Her gym exercise has yielded good results.(她的健身房练习取得好的结果)D)Her effort to keep fit is really praiseworthy.解析:关注第二句,期间读到的单词全部在错项中有所体现。答案是C。第十四页,讲稿共四十五页哦 Longer ConversationsLonger Conversations

adoptions each year in the United States alone.Some people prefer to adopt infants.Others adopt older children.Some couples adopt children from their own families,they all adopt children for the same reason.They care about children(第第26题题)and want to give their adopted child a happy life.第二十一页,讲稿共四十五页哦Most adopted children know that they are adopted.Psychologists and childcare experts generally think this is a good idea.However,many adopted children or adoptees have very little information about their biological parents.As a matter of fact,it is often very difficult for adoptees to find out about their birth parents because the birth records of most adoptees are usually sealed.The information is secret,(第第27题题)so no one can see it.Naturally,adopted children have different feelings about their birth parents.Many adoptees want to search for them,but others do not.The decision to search for birth parents is a difficult one to make.Most adoptees have mixed feelings about finding their biological parents.(第第28题题)Even though adoptees do not know about their natural parents,they do know that their adoptive parents want them,love them and will care for them.(第第29题题)第二十二页,讲稿共四十五页哦Questions 26 to 29 are based on the passage youve just heard.26.According to the speaker,why do some couples adopt children?A)They care a lot about children.B)They need

much to do with love.第二十四页,讲稿共四十五页哦 Compound DictationCompound Dictation
