I.Introduction

As we all know,in recent years,English teaching has almost spread to every school in our country,and the phonetic teaching has also attracted high attention.However,at the present,the speech sound in English teaching has not been valued enough,especially in the western rural poor areas,instead,it was almost ignored in primary schools.This paper mainly focuses on the problem and discusses some proposals for it.The research on phonetic teaching at home and abroad,which was out of question laying a foundation for the research,but the temporary research at home and abroad still exist some shortcomings.The study abroad considered that “the younger,the easier to learn a language”,and did neither mention the classroom teaching of specific speech sound,nor discuss it with different regions.Although the domestic researches mentioned the problems existing in the primary school English phonetic teaching and emphasized the importance of the primary school English teaching,the method was not concrete, for they rarely discussed the regional differences of primary school phonetic teaching.In view of this,the author tried to employ the methods of survey and interview to carry out investigation,in which he found out the main problems existing in the primary school English phonetic teaching in rural areas.Meanwhile,combining with the research results of phonetic teaching both at home and abroad,the author summarizes the methods how to carry out the pronunciation teaching in primary school effectively.

Of course,we can see pronunciation as the foundation of both listening and speaking.So you must have very good command on pronunciations before you can speak;and only when you articulate the target languages clearly and correctly,can you understand other people’s pronunciation ability.Critical period is also known as the sensitive period,which refers to the individual development process,when the environment has the greatest impact on learning Language.In the critical period,the acquisition of language is the easiest.However,if you miss it,the ability of the pronunciation acquisition will be limited.For elementary school students who learn English at first time,a solid foundation of speech is the step stone for the mastery of English in the future.However,not all English teachers value the importance of phonetic teaching,especially in rural elementary school in the western poor regions such as villages, where phonetic teaching is usually ignored.In the second academic semester of2014,the author was assigned to Zhezhuang Central Primary School of Hezhang County in Guizhou Province to do his teaching practice for three months,during which he was an English teacher of3classes in Grade four.In his spare time,he went to attend other English teachers’lessons in different classes and grades.He found some problems existing in some teachers’English pronunciation, and inadequate attention being paid to English phonetic teaching.After communicating with the

teachers there,the author arrived at a conclusion:they thought it is unnecessary to attach too much importance of phonetic teaching in elementary schools,especially in rural ones.

In addition,the author also discovered the pupils in Grade Four and other grades had very poor knowledge of English pronunciation.In view of the present situation and out of curiosity, the author decided to take Zhezhuang Primary School as a case,with an attempt to carry out some investigations on the existing problems of English phonetic teaching in the rural primary schools and the strategies for them.The author hopes the findings in his research will contribute to improve students’ability of English pronunciation in rural primary school.

II.Problems of Guizhou Rural Primary School English Phonetic Teaching In terms of the present development of the education in China,English teaching has been popularized in almost every school.However,a lot of primary schools in the western underdeveloped regions still didn’t have English class;a case in point is some rural schools in Bijie city.According to the author’s knowledge,in Zhezhuang village,Hezhang County,Bijie city,except for the central primary school,other schools almost had no English class.Even though some primary schools had English class,they took English as an auxiliary subject,having only two classes a https://www.360docs.net/doc/5711510316.html,st year,the author had the honor to come to Zhezhuang village township central primary school of Hezhang County in Province to do his teaching practice for three months.He taught English in3classes in Grade four,which provided him the opportunity to carry out a preliminary investigation on students’English pronunciation.The findings, however,was not encouraging.Meanwhile,the author also attended other English teachers’class in different classes and grades,where he found no more encouraging situation for students’English pronunciation.The problems were summarized as the follows.

To begin with,the teachers did not formulate an overall pronunciation teaching goal,nor did they have any systematic teaching plan.In the classes of middle and high grades,the teachers basically went by the books,ignoring English phonetic teaching in the junior stage,for the teachers failed to attach adequate attention to phonetic teaching.Secondly,the teachers’awareness of phonetic teaching was quite weak;they didn’t take the speech sound elements implied in the textbooks into consideration seriously.Besides,as they had very poor knowledge about English pronunciation,they didn’t often teach speech sound actively.Thirdly,although most of the teachers had strong ability of pronunciation,they did not have a good command of relevant knowledge of voice,or they were lack of the basic knowledge,which made it difficult to carry out the phonetic teaching.It was influenced on the dialectal accent accounts was another important factor,which led to the students’mispronunciation.What’s more,their self-independent learning ability was poor and the external condition of English speech sounds

were relatively weak;therefore,they would not take the initiative to find suitable extracurricular video and audio data,etc.to help them to improve their pronunciation.

2.1The Difficulty in Carrying out Phonetic Teaching in Primary School

The elementary school students are naughty and active.When you go into an English classroom to teach them English,you will find that it is not an easy work to be a primary English teacher.However,it is not only the students themselves that make it hard to teach the English speech sounds;at the same time,there are also many other factors.We can discuss some of them as the following aspects:(1)The attention to the phonetic teaching varies in different schools. Although English teaching almost reaches every primary school,phonetic teaching is still ignored in most of them.It is thought unnecessarily to teach the speech in elementary school, and it is taken for granted that having the ability to use simple English words and sentences for pupils is enough.(2)The teachers themselves have different degrees of speech sound knowledge. Students who are taught by the teachers with rich knowledge and experience of teaching can obviously learn much more knowledge of speech sounds and can improve their own pronunciation gradually.(3)The differences in individual students’interest.As a matter of fact, not every student is interested in English,much of them don’t know the importance of English for primary school students,nor do they know how important of learning English speech sounds. Because of individual differences,the ability of grasping the skills for improving speech sounds is different as well.Some students have stronger ability to acquire English speech sound,and they can also control the voice well.(4)Parents’different attitudes towards English phonetic teaching.The requirements of different families for children minders learning are different.The parents who think English very important will supervise and urge their children to study hard, while some other parents consider that English far less important than Chinese and mathematics. Especially the parents of the students in the primary school think it is enough for their children have a good command on Chinese and mathematics,as to English,they can learn it in junior high school.

2.2The Prevalent“Dumb English”in Primary School English Teaching

“Dumb English”is common in foreign languages teaching,the learners study English mainly by writing and paper-testing instead of speaking and listening,and over emphasize the examination and neglect the training of listening and speaking.As a result,“the deaf-mute phenomenon”is quite common.The problems existing in the phonetic teaching has a long history.In many areas,“Dumb English”is still a very common phenomenon in the English teaching of primary and secondary schools.Of course,there must be some reason for this.In the actual teaching process,you will find that the first obstacle to the pupils at the beginning of English learning is the pronunciation problems.During the last year when the author did the

teaching practice in Hezhang County,he found students were very poor in pronouncing English words.Teaching English word“toy”is a good demonstration,in which it would require the teacher to teach students for dozen times before they could read it.The reason is that they don’t understand it,they can’t read it out,and thus we get the so-called“Dumb English”.The pupils without accepting special introductory of speech teaching usually may get into trouble during the speech sound learning,so they will take some special measures.It is a good example that to use a Chinese characters or pinyin to replace the pronunciation of an English word.Actually,there are a certain rule between the pronunciation and spelling of English words,but for pupils who don’t know the phonetic symbols,they frequently use Chinese characters or pinyin to take the place of the pronunciation of a word,such as substituting“赖尺”for“light”,“喔奥”for“wall”,“死壮”for“strong”,etc.Thus they tend to make some mistakes in the process of spelling. What’s worse,they cannot read the sentences and dialogues accurately both with proper pronunciation and intonation.

2.3The Difficulty in Memorizing Words for Pupils

During the internship period,the author taught English in grade four,where he had students dictated English words three times respectively in each class.For each dictation,he gave them ten simple words such as“key”,“feel”,“fan”,“wall”and“toy”.However,each time about one fifth of the students didn’t hand in their dictation books.Even among the students who handed in their books,no one could spell the whole words,and very few students could correctly write more than three words.So what is the reason that makes it difficult to remember the words for primary school students?According to the author’s experience of having been learning English for over10years and the communication with other English learners,and English teachers,he comes to a general conclusion:the memorization of English words is closely associated with combining the sound,form and meaning together,in which sound(refers to the ability to read and spell the words)is the premise.As a matter of fact,most pupils can neither read nor spell. They don’t know the rules of pronunciation,and even do not understand the phonetic symbols. In addition,they not only memorize words slowly,they will also soon forget the words that they have https://www.360docs.net/doc/5711510316.html,ually,students are inclined to employ the inefficient methods to memorize words.A common method is mechanically copying a word many times.Another is combining letters with the pronunciation of English words.In the author’s class some students copied a word for dozens of times,which was a waste of time,for they got half result with twice effort, especially for the long words.Suppose the students memorized the English words in accordance with the rules of pronunciation,they would get twice the result with half the effort.

III.The Methods of Improving the Teaching of English Speech Sounds in Primary School

3.1Teaching the Phonetic Symbols and Letters together

In the process of teaching English letters,the teacher may teach students the letters’pronunciation of phonetic forms at the same time.Especially the vowel letters,such as A/ei/,E/i:/,I/ai/,O/?u/,U/ju:/,thus the students can learn the English phonetic pronunciation as they learn English letters’pronunciation.English letters contain most of the English phonetic symbols.Actually,most speech sounds had been taught after teaching letters pronunciation.Here we can classify the26English letters by speech sounds as follow:/ei/, A-H-J-K;/i:/,E-B-C-D-G-P-T-V;/e/,F-L-M-N-S-X-Z;/ju:/,U-Q-W;I,O,R was special.In the primary school,we often found that many students cannot remember the words,nor were they willing to read and memorize words.But many teachers often ascribed the problem to the students’laziness.Even they did not understand what the teacher taught.Given the fact that some students had their anguish,how could we force them to read,or to memorize new words? That the students cannot remember the word can be attributed to their lack of necessary knowledge of speech sounds.The author had such a kind of experience.As we all know,English words are different from Chinese characters.The shape of English words has a direct connection with its pronunciation,so we can remember a lot of words according to the pronunciation.For another thing,if one cannot read the word,it will be difficult for him/her to remember it as well. If the students can learn English speech sounds,they will be able to find out the corresponding pronunciation by letter combinations,and they can easily spell words and read the text fluently and accurately.Therefore,we must value the teaching of phonetic knowledge to make it to be a tool for students to memorize English words.

3.2Putting the Phonetic Teaching of the Speech,Letters and Words together

This method was based on“Teaching the phonetic symbols and letters together”.To be specific,the teacher put those words of the same pronunciation by letter,or in accordance with the basic rules of English pronunciation,spelling simpler words to teach together at the same time.It aimed at making the students learn some basic words while learning letters’pronunciation and the phonetic pronunciation.Such as the letter“A”/ei/,name,cake,date;the letter“I”/ai/,five,time,kite.Meanwhile,the improvement of listening and speaking skills benefited from speech sounds.If students failed to develop a good sense of speech sound,it would be difficult to improve their spoken English and listening ability.This is because only when the students learn speech sounds well,can they understand phonetic materials well and can they speak English confidently.Thus,they did not only enhance the confidence of learning

English,but improved their enthusiasm to learn English.So we could say that to learn English speech sounds were the premise to improve one’s listening and speaking ability.

3.3The Phonetic Teaching of Classifying Phonetic Symbols and Vocabulary

Teachers should teach the words in accordance with the same pronunciation rules. Classification can be repeated many times,usually will be a word in vowels,consonants,syllable stress,unstressed syllable multiple classification.The classification aims to help students to master the phonetic symbols and pronunciation to remember these words.As/ei/:cake,face, name,make,hate;/ai/:I,like,kite,five,rice,nine.Certainly,speech sound is a factor that cannot be ignored in the primary school English teaching.However,in actual teaching practice, many English teachers want to teach the speech sounds but they can’t find a good teaching method.And it is also necessary to do a lot of boring practice for primary school English phonetic teaching;so if the teachers do not deal with it properly,it may discourage students’study enthusiasm.So we need to pay more attention to the proper methods and techniques in the phonetic teaching.The following methods are proposed by the author in the hope of providing some references to improve English phonetic teaching in the rural primary schools.

3.4Applying Heuristic Teaching

The heuristic teaching means that the educators do the education of the inspiration,the initiative to obtain knowledge,develop intelligence,cultivate personality,forming the process of the perfect personality.It is a kind of teaching method which can make the students to study positively and develop both physically and mentally.In an English class,teachers ought to inspire the students to find out the connection between sound and sound,letter and letter,word and word,even between the two languages;and do more practice to deepen the understanding and consolidate students’memorization.Here the author would like to illustrate this point with the search of the pronunciation rules about the letter“I”.We can divide the whole class into two groups and ask them go to look for the laws of the two patterns of the pronunciation rules about the letter“I”,while the first group work on the English words“six,his,big,pig,fish,swim,this, etc”.While the other group“ice,five,kite,bike,rice,nine and the like,and so on”.Within the time given,the teacher can judge which group find out more relevant words and sum up the laws and give them some rewards.Finally the teacher provides a summary to let students know what the two main pronunciations of the letter“I”in different words.

In the process of the authors’teaching practice,he applied some of the methods above in two classes,where he found that the students’pronunciation had improved quite a lot comparing to their performance three months ago,but the other class made little progress.Therefore,the author hope that all the rural primary school English teachers to use more vivid and interesting teaching methods,so as to improve the level of elementary students’phonetic ability,and to

narrow the gap with the students from other regions.

IV.Conclusion

This paper mainly discussed the existing problems of English phonetic teaching in rural primary schools and the teaching strategies for them.And the author worked out the problems on the basis of communication with the teachers and students in this school,as well as his observation in the classrooms.In view of this,the author tried to employ the methods of survey and interview to carry out investigation,in which he found out the main problems existing in the primary school English phonetic teaching in rural areas.Firstly,it is still difficult to carry out phonetic teaching in the primary School.Besides,the“Dumb English”is prevalent in the primary school.What’s more,memorizing words is a hard job for the pupils.Meanwhile, combining with the research results of phonetic teaching both at home and abroad,the author summarizes the methods how to carry out the pronunciation teaching in primary school effectively.The main methods are to apply the heuristic teaching,to teach the phonetic symbols and letters together,to put the phonetic teaching of the speech,letters and words together and to classify phonetic symbols and vocabulary in the phonetic teaching.In addition,the paper aims to attract certain attention from more experts,scholars to the rural primary school English phonetic teaching,which will encourage them to carry out more researches on the related problems,and provide the reference for the rural primary school English phonetic teaching,thus to a certain extent,improving the rural primary school students English ability.

However,because of the author’s personal shortages in both knowledge and ability,this paper still had the following deficiencies.To begin with,the author only carried out the investigation on the small part of the primary schools in the township Hezhang County,the data perhaps was not so representative enough.Secondly,the author had not collected enough literature for the https://www.360docs.net/doc/5711510316.html,st,since this was a tentative research,the arrangement of the investigation and interview was not so perfect,and the analysis of the investigation was not so thorough.Therefore,whether the research conclusion was adaptable for all of the English phonetic teaching in the rural middle schools or not still needed more specific cases to verify.

In the future,the author will constantly improve the knowledge structure and the ability of research,and continue to concentrate on finding out the problems of English phonetic teaching in rural primary school and searching the teaching strategies.What’s more,in the future research the author will try to do the surveys among more areas and more schools,so as to work out more findings.

W:您教英语多少年了?

T:三年了,之前教的是语文,后来缺英语教师学校就让我教英语。

W:那么您教英语的这些年对于英语教学有什么感想吗?

T:前两年英语被当作主要科目,后来就被当作副科了,一周只有两节课。W:请问您认为英语语音对学生英语学习有多重要?

T:我认为很重要,但是在小学并不那么重要。

W:您为什么认为在小学并不是很重要?

T:一方面,小学生对学习语音不感兴趣;另外一方面,初中有更系统的语音教学。

W:在你的教学过程中有涉及语音教学吗?

T:有。

W:您认为小学英语语音教学主要包含哪些方面?

T:我认为语音教学包括字母的读音,单词的发音,字母组合的发音和一些发音规律,清辅音,浊辅音发音规律,发音部位以及节奏。

W:您认为对于小学生来说什么样算是好的语音?

T:在日常生活中自然渗透到学生脑海中的,听起来很舒服的,应该算是好的语音。

W:在小学英语教学阶段是否进行音标教学或者是拼读单词教学?

T:是,三年级就开始讲授了。

W:您教的学生英语语音发音状况怎么样?

T:好的较少。少部分学生一教就会,但是多数学生要重复好几遍才能勉强掌握。所以针对大多数学生的情况,要尽量多重复几遍才可以。

W:语音不好的学生比例占有多少?什么原因呢?

半张纸合集

《半张纸》给了我们什么? ——浅评张悦老师《半张纸》的课堂教学 浙江慈溪中学黄孟轲 一、探讨外国现代派小说教学中有关文本的几个要素:从张悦《半张纸》堂课教学探讨说起 1、贴着文本教:以内容激活教法,让学生自由进入 (1)以一条激情线引领学生自由进入。整堂课从老师一张白纸切入,围绕主人公两年间的人生涌动着的一条感情激流,让学生循着人物感情从愉悦幸福——痛苦低沉——抬头坦然快乐,让学生一层层一步步地去凸显感悟他们这短短两年间“爱”的心路历程,生命价值意义。 (2)以内容激活其个性化的教学技艺。教法技巧服从于教学的内容听课。许多老师也常常看重教师的教学技艺、教学风采,上课如何精致、如何精彩。我们老师的好多课,老师看似运用多种技术手段,师生进行着多种活动,师生对话频繁,但仔细考察,其所教内容被热热闹闹掩盖了,而文本却一直在表面滑行,这样的课对学生的智性发展,对听说读写,对文学作品的欣赏难以产生实质性的作用。王荣生教授说这是“乱耕别人的田,荒了自己的地”。 (3)整堂课,贴着文本让学生在还原想象中贴着主人公的灵魂去体悟欣赏文本内涵。 老师在教学中,因着文本结构的空白、文本语言的未确定性,因着大量的隐含在文本语言背后内容,非常注重学生的智性想象还原本文内容,实现对斯特林堡在文本语境中达到多义之功能。如关于“艾丽丝”这个名字,15,11与50,50 两个电话号码,给马车行老板打电话等等,看歌剧前后的情景就让学生在自由的想象中读出自己的理解想象,或填上自己的阅读感悟。 这样以冰山八分之一角去挖掘语言背后的八分之七。课堂中有几个精彩互动对话片段,譬如老师同学生之间的英文名字对白,结尾处想象几年以后在艾丽丝的墓前主人公会对他的妻子说些什么,这样丰富了作品的内涵拓展了其容量与意义,其实也有所触动文本的节构是艺术,是思想与精神的容器。这是与作家所以这样写的意义由写相吻合,也是作为现代小说艺术功能的阅读教学意义。 2、预设精当,生成自由 (1)整堂课流程从爱切入,一线牵全篇——还原作品的情景,挖掘小说灵魂。老师、学生、文本互为贯穿,教师自身充分发挥其机智灵动、自如美声的教学风格,使其教学内容的选择和谐共生,她牢牢抓住小说中主人公婚恋,从“爱”字入手,对教学内容所做的创造性的开发,即在半张纸的世界中展开的发挥。 (2)师生自由探讨,灵活对话,愉悦体验,在合作探究共享中享受文学之美丽。没有借用其他媒体手段,教师的一支粉笔一颗心一张嘴关联着和谐者学生在阅读鉴赏过程中智性个性,把经典小说的爱之痛爱之美,把生命中不能承受之重,阐释得美妙淋漓。让学生真正体验到经典的魅力。 3、“爱”的轻与重:凸出文本生命要素,还原空白背后之美之痛。 板书中有一核心词:“化轻为重”,就是生命中不能承受之轻。这一轻一重都围绕“爱”感悟而展开。小说情节结构的时时断裂或隐匿,师生一道在想像联想中填补,完成爱的轻与重的艺术整体的构成。 整堂课都以在努力地打开文本褶皱处,突显爱的美丽,两年生活种种魅力,

半张纸阅读练习及答案

[瑞典]斯特林堡 最后一辆搬运车离去了;那位帽子上戴着黑纱的年轻房客还在空房子里徘徊,看看是否有什么东西遗漏了。没有,没有什么东西遗漏,没有什么了。他走到走廊上,决定再也不去回想他在这寓所中所遭遇的一切。但是在墙上,在电话机旁,有一张涂满字迹的小纸头。上面所记的字是好多种笔迹写的;有些很容易辨认,是用黑黑的墨水写的,有些是用黑、红和蓝铅笔草草写成的。这里记录了短短两年间全部美丽的罗曼史。他决心要忘却的一切都记录在这张纸上——半张小纸上的一段人生事迹。 他取下这张小纸。这是一张淡黄色有光泽的便纸条。他将它铺平在起居室的壁炉架上,俯下身去,开始读起来。 首先是她的名字:艾丽丝——他所知道的名字中最美丽的一个,因为这是他爱人的名字。旁边是一个电话号码,15,11——看起来像是教堂唱诗牌上圣诗的号码。 下面潦草地写着:银行,这是他工作的所在,对他说来这种神圣的工作意味着面包、住所和家庭,也就是生活的基础。有条粗粗的黑线画去了那电话号码,因为银行倒闭了,他在短时期的焦虑之后又找到了另一个工作。 接着是出租马车行和鲜花店,那时他们已经订婚了,而且他手头很宽裕。 家具行,室内装饰商——这些人布置了他们这寓所。搬运车行——他们搬进来了。歌剧院售票处,50,50——他们新婚,星期日夜晚常去看歌剧。在那里度过的时光是最愉快的,他们静静地坐着,心灵沉醉在舞台上神话境域的美及和谐里。 接着是一个男子的名字(已经被划掉了),一个曾经飞黄腾达的朋友,但是由于事业兴隆冲昏了头脑,以致又潦倒到无可救药的地步,不得不远走他乡。荣华富贵不过是过眼烟云罢了。 现在这对新夫妇的生活中出现了一个新东西。一个女子的铅笔笔迹写的“修女”。什么修女?哦,那个穿着灰色长袍、有着亲切和蔼的面貌的人,她总是那么温柔地到来,不经过起居室,而直接从走廊进入卧室。她的名字下面是L医生。 名单上第一次出现了一位亲戚——母亲。这是他的岳母。她一直小心地躲开了,不来打扰这新婚的一对。但现在她受到他们的邀请,很快乐地来了,因为他们需要她。 以后是红蓝铅笔写的项目。佣工介绍所,女仆走了,必须再找一个。药房——哼,情况开始不妙了。牛奶厂——订牛奶了,消毒牛奶。杂货铺、肉铺等等,家务事都得用电话办理了。是这家的女主人不在了吗?不,她生产了。 下面的项目他已无法辨认,因为他眼前一切都模糊了,就像溺死的人透过海水看到的那样。这里用清楚的黑体字记载着:承办人。 在后面的括号里写着“埋葬事”。这已足以说明一切!——一个大的和一个小的棺材。 埋葬了,再也没有什么了。一切都归于泥土,这是一切肉体的归宿。 他拿起这淡黄色的小纸,吻了吻,仔细地将它折好,放进胸前的衣袋里。 这两分钟里他重又度过了他一生中的两年。 但是他走出去时并不是垂头丧气的。相反地,他高高地抬起了头,像是个骄傲的快乐的人。 因为他知道他已经尝到一些生活所能赐予人的最大的幸福。有很多的人,可惜,连这一点也没有得到过。 7.下列对这篇文章有关内容的理解和赏析,不正确的两项是( ) ( )(5分) A.以“最后一辆搬运车离去了;那位帽子上戴着黑纱的年轻房客还在空房子里徘徊”开头,为全文奠定了一个悲情低沉的情感基调,同时设置了悬念,吸引读者的阅读兴趣,还与后文相关情节形成了照应。 B.第一段中说:“没有,没有什么东西遗漏,没有什么了。”这句话意在表明主人公东西搬得非常干净,做事十分细心。 C.作者在第十一段中写道:“下面的项目他已无法辨认,因为他眼前一切都模糊了,就像溺死的人透过海水看到的那样。”意在表现男主人公情感已极度哀伤,像溺水之人窒息的感觉,为后文他积极乐观地振作起来做铺垫。 D.《半张纸》采用倒叙的方式回忆了男主人公的家庭琐事,情节波澜起伏,情感真实动人。 E.《半张纸》以一千五百字的简短篇幅,用十来个电话号码展示一幅幅生活画面,表现主人公一生中充满悲欢离合的两年,旨在表现20世纪初的瑞典资本主义社会里小人物无法掌握自己的命运却又对幸福充满坚定乐观的期待,选材别致,语言平实,构思新颖。 8.小说的结尾画线句子“相反地,他高高地抬起了头,像是个骄傲的快乐的人。”请结合文章谈谈你对这句话的理解。(4分) 9.文章为什么以“半张纸”为题目?请结合文本加以探析。 (5分) 答案: (三)文学类文本阅读(14分) 7.(5分)B C (选B得3分,选C得2分)本题考查鉴赏小说的能力,主要是对小说的文体特征和主要表现手法的分析。B项句意重在表现妻子双双离世后男主人公一无所有,情绪极度低落,同时准备告别过去。C项句子的作用不是为后文做铺垫,而是与后文男主人公振作起来形成反衬,哀伤愈深,振作弥坚,更具感染力。 8.(4分)本题考查小说的语言艺术鉴赏,理解重要词句的含义。答案:①“相反地”一词意在进行一种对比,当经历了人生的大不幸后很多人将悲痛延续无法自拔,但本文的男主人公却更加坚定乐观。(1分)②“高高地抬起了头”这个动作塑造出男主人公不屈服于厄运,经历失去亲人的痛楚后依然积极向上的形象。(1分)③卒章显志。不幸的,我们任它随时光流逝,更重要的是把握现在拥有的,去开拓更美好的未来。(2分) 9.(5分)本题考查小说的主旨理解和小说标题的作用。答案:①从主题上看,半张纸浓缩了主人公两年喜乐悲愁,半张纸上记录的内容折射出人生的无常和幸福对人的积极意义。(2分)②从

《半张纸》阅读答案

半张纸【瑞典】斯特林堡最后一辆搬运车离去了;那位帽子上戴着黑纱的年轻房客还在空房子里徘徊,看看是否有什么东西遗漏了。没有,没有什么东西遗漏,没有什么了。他走到走廊上,决定再也不去回想他在这寓所中所遭遇的一切。但是在墙上,在电话机旁,有一张涂满字迹的小纸头。上面所记的字是好多种笔迹写的;有些很容易辨认,是用黑黑的墨水写的,有些是用黑、红和蓝铅笔草草写成的。这里记录了短短两年间全部美丽的罗曼史。他决心要忘却的一切都记录在这张纸上――半张小纸上的一段人生事迹。他取下这张小纸。这是一张淡黄色有光泽的便条纸。他将它铺平在起居室的壁炉架上,俯下身去,开始读起来。首先是她的名字:艾丽丝――他所知道的名字中最美丽的一个,因为这是他爱人的名字。旁边是一个电话号码,15,11――看起来像是教堂唱诗牌上圣诗的号码。下面潦草地写着:银行,这里是他工作的所在,对他说来这神圣的工作意味着面包、住所和家庭――也就是生活的基础。有条粗粗的黑线划去了那电话号码,因为银行倒闭了,他在短时期的焦虑之后又找到了另一个工作。接着是出租马车行和鲜花店,那时他们已订婚了,而且他手头很宽裕。家具行,室内装饰商――这些人布置了他们这寓所。搬运车行――他们搬进来了。歌剧院售票处,50,50――他们新婚,星期日夜晚常去看歌剧。在那里度过的时光是最愉快的。他们静静地坐着,心灵沉醉在舞台上神话境域的美及和谐里。接着是一个男子的名字(已经被划掉了),一个曾经飞黄腾达的朋友,但是由于事业兴隆冲昏了头脑,以致又潦倒到无可救药的地步,不得不远走他乡。荣华富贵不过是过眼烟云罢了。现在这对新婚夫妇的生活中出现了一个新东西。一个女子的铅笔笔迹写的“修女”。什么修女?哦,那个穿着灰色长袍、有着亲切和蔼的面貌的人,她总是那么温柔地到来,不经过起居室,而直接从走廊进入卧室。她的名字下面是L 医生。名单上第一次出现了一位亲戚――母亲。这是他的岳母。她一直小心地躲开,不来打扰这新婚的一对。但现在她受到他们的邀请,很快乐地来了,因为他们需要她。以后是红蓝铅笔写的项目。佣工介绍所,女仆走了,必须再找一个。药房――哼,情况开始不妙了。牛奶厂――订牛奶了,消毒牛奶。杂货铺,肉铺等等,家务事都得用电话办理了。是这家女主人不在了吗?不,她生产了。下面的项目他已无法辨认,因为他眼前一切都模糊了,就像溺死的人透过海水看到的那样。这里用清楚的黑体字记载着:承办人。在后面的括号里写着“埋葬事”。这已足以说明一切!――一个大的和一个小的棺材。埋葬了,再也没有什么了。一切都归于泥土,这是一切肉体的归宿。他拿起这淡黄色的小纸,吻了吻,仔细地将它折好,放进胸前的衣袋里。在这两分钟里,他重又度过了他一生中的两年。但是他走出去时并不是垂头丧气的。相反地,他高高地抬起了头,像是个骄傲的快乐的人。因为他知道他已经尝到一些生活所能赐予人的最大的幸福。有很多人,可惜,连这一点也没有得到过。(选自人教版《外国小说欣赏》)15.下列对这篇小说有关内容的理解和赏析,不正确的两项是()()(4分)A这是一篇富有怀旧气息的微型小说,基调是悲伤的,浮在表面的字和沉在深处的情,仅由半张记录主人公一生中两年“全部美丽的罗曼史”的纸条存着。B小说主体情节是那半张纸上的字引起的回忆。忘却和怀念构成了对比;主人公将这段爱情认定为人生最大的幸福,这幸福之大和纸条之小又构成了对比。C小说聚焦于“那一刻”:一生中的“两年”那一刻;两年中的“一个大的和一个小的棺材”出现的那一刻;两分钟里主人公“高高地抬起了头”走出去的最后那一刻。D 小说注重肖像、心理、细节的刻画。半张纸让他重温诸多的人生欢乐,给予了他精神慰藉,他吻着淡黄色的小纸等细节描写,写出了主人公对半张纸的珍爱。E作者不惜笔墨,精细地描绘了半张纸的大小、形状、颜色、质地,甚至连纸上的字迹也一一作了说明,这样,半张纸像电影特写镜头似的强烈吸引着读者。 15.AD(A项,小说的基调应该是温暖的。D注重肖像的刻画不对。)16. “半张小纸上的一段人生事迹”有哪些“事迹”,请简要概括。(6分)初恋的热情,失业的恐慌,新婚的甜蜜,妻子的怀孕,即将做父亲的惊喜与忙碌,丧妻夭子的巨大悲痛……(一点1分,共6分,如还答到别的“事迹”,只要符合

网站设计方案定稿

一、项目目标 1、树立全新企业形象 企业网站的形象往往决定了客户对企业产品的信心。建立具有国际水准的网站能够极大的提升企业的整体形象。 2、增强销售力 销售力指的是产品的综合素质优势在销售上的体现。销售的成功与否,除了决定于能否将产品的各项优势充分地传播出去之外,还要看目标对象从中得到的有效信息有多少。由于互联网所具有的“一对一”的特性,目标对象能自主地选择对自己有用的信息。这本身已经决定了消费者对信息已经有了一个感兴趣的前提。使信息的传播不在是主观加给消费者,而是由消费者有选择地主动吸收。同时,产品信息通过网站的先进设计,既有报纸信息量大的优点,又结合了电视声、光、电的综合刺激优势,可以牢牢地吸引住目标对象。因此,产品信息传播的有效性将远远提高,同时亦即是提高了产品的销售力。 3、提高附加值 购买产品不仅买的是那些看得见的实物,还有那些看不见的售后服务。这也就是产品的附加值。产品的附加值越高,在市场上就越有竞争力,就越受消费者欢迎。因此,企业要赢得市场就要千方百计地提高产品的附加值。在现阶段,传统的售后服务手段已经远远不能满足客户的需要,为消费者提供便捷、有效、即时的24小时网上服务,是一个全新体现项目附加值的方向。世界各地的客户在任何时刻都可以通过网站下载自己需要的资料,在线获得疑难的解答,在线提交自己的问题。 总结上述几点,****机械有限公司网站建设目标可总结如下: 1) 帮助企业建立有效的企业形象宣传、企业风采展示、公司产品宣传,打造“****有限公司”新形象。 2) 充分利用网络快捷、跨地域优势进行信息传递,对公司的新闻进行及时的报道。 1.3 网站设计原则 商业性原则 作为企业商业运作的一个组成重要部分,服务于****机械有限公司企业文化的对外传播,服务于企业与客户、企业与员工沟通渠道的建立,完善企业服务体系,创造更多的商业机会,为企业经营者提供科学决策辅助。 品牌性原则 为客户提供有价值的产品和服务,充分体现“****机械有限公司”品牌优势,重点塑造企业网络品牌的个性化形象,使注意力资源尽可能地转化成品牌消费,建立忠诚“****机械有限公司”消费群体。 经济性原则 建立适合****机械有限公司自身需求的网络平台,提供广泛的涵盖用户多种需求的功能,数据处理方式灵活以满足高度用户化的需求,节省网站建设成本,并确保其较好的拓展性和开放性;同时网站具有基于WEB界面的管理后台,企业能够自主的对网站中大部分内容作更新、修改操作,节省了企业网站的运营成本,提高了信息更新、传播效率。 扩充性原则

网站设计方案定稿范文

网站设计方案定稿

一、项目目标 1、树立全新企业形象 企业网站的形象往往决定了客户对企业产品的信心。建立具有国际水准的网站能够极大的提升企业的整体形象。 2、增强销售力 销售力指的是产品的综合素质优势在销售上的体现。销售的成功与否,除了决定于能否将产品的各项优势充分地传播出去之外,还要看目标对象从中得到的有效信息有多少。由于互联网所具有的“一对一”的特性,目标对象能自主地选择对自己有用的信息。这本身已经决定了消费者对信息已经有了一个感兴趣的前提。使信息的传播不在是主观加给消费者,而是由消费者有选择地主动吸收。同时,产品信息经过网站的先进设计,既有报纸信息量大的优点,又结合了电视声、光、电的综合刺激优势,能够牢牢地吸引住目标对象。因此,产品信息传播的有效性将远远提高,同时亦即是提高了产品的销售力。 3、提高附加值 购买产品不但买的是那些看得见的实物,还有那些看不见的售后服务。这也就是产品的附加值。产品的附加值越高,在市场上就越有竞争力,就越受消费者欢迎。因此,企业要赢得市场就要千方百计地提高产品的附加值。在现阶段,传统的售后服务手段已经远远不能满足客户的需要,为消费者提供便捷、有效、即

时的24小时网上服务,是一个全新体现项目附加值的方向。世界各地的客户在任何时刻都能够经过网站下载自己需要的资料,在线获得疑难的解答,在线提交自己的问题。 总结上述几点,****机械有限公司网站建设目标可总结如下:1) 帮助企业建立有效的企业形象宣传、企业风采展示、公司产品宣传,打造“****有限公司”新形象。 2) 充分利用网络快捷、跨地域优势进行信息传递,对公司的新闻进行及时的报道。 1.3 网站设计原则 商业性原则 作为企业商业运作的一个组成重要部分,服务于****机械有限公司企业文化的对外传播,服务于企业与客户、企业与员工沟通渠道的建立,完善企业服务体系,创造更多的商业机会,为企业经营者提供科学决策辅助。 品牌性原则 为客户提供有价值的产品和服务,充分体现“****机械有限公司”品牌优势,重点塑造企业网络品牌的个性化形象,使注意力资源尽可能地转化成品牌消费,建立忠诚“****机械有限公司”消费群体。 经济性原则 建立适合****机械有限公司自身需求的网络平台,提供广泛
