英语口腔训练
英语口语模仿
英语口语模仿1.自我口腔训练在自学英语的过程中，很多同学的发音是通过一遍又一遍地模仿磁带练出来的，这个过程比较辛苦，需要灵敏的听觉和超强的模仿能力才能够模仿得唯妙唯肖，而为了练发音，可能会用坏好几台复读机。
练发音的目的是为了先把自己的嘴巴打通，使口腔肌肉和发音器官适应英语的发音，经历完这个过程不代表你遇到外国人就能够流利地沟通，因为讲一口流利的英语不单单只是嘴皮子灵活或背很多单词和句子就能搞定的，但这个过程至关重要。
2.自我训练标准首先，要把每一个单词的发音都发准确，要认真地模仿一些慢速而且简单的材料，目前市面上的慢速英语读物很多，自己要耐着性子认真模仿发音，这个过程比较艰苦，但是不经历这个过程，以后积累的单词、句子和文章说出来就一错再错，最后讲出来的英语只有自己听得懂。
如果你觉得自己没有什么模仿天赋，或者自己怎么练都练不好，或者发现自己的发音真的无药可救，那么说实话，别人也帮不上忙，纠正发音是很浪费时间的，就算当时发音纠正股哟了，过了3分钟，不标准的发音再次会被打回原形。
接下来，在确定对单词发音已经准确的前提下，开始模仿大量句子和文章，在模仿过程中练好英语的语调intonation, 中文的发音和语调是一致的，我们四个调把发音钉死了，所以单字读好了，句子也能读得好。
但是英文不一样，一个单词的发音发好了还不止，单词放到句子中还需要变调，叫做语调。
那么如何选择、使用和定义口语练习标准：1. 如何选择口语书籍既然是口语书籍，肯定不能少的就是有mp3录音的书籍，还有书本涵盖的是你想学习的那个行业的英语口语。
提醒一下：不要买那些美国街头口语类的书籍，因为你学了也没地方用，只能自娱自乐或忽悠时用用。
2. 如何学习自己选择的口语书首先，看书中有多少音频文件，先拿两三个放到自己的mp3播放器里;然后，先不要看书，把这两三段mp3音频好好利用时间听个几十遍，一段也就几分钟，所以不会花你很长时间，在听的过程中尝试跟读模仿(声明：即使你不知道什么意思也可以模仿跟读，因为婴儿就是这么模仿父母讲话的)，看自己能听懂多少，能跟读多少内容;接下来，你带着你听不懂的疑问去翻开书看看自己到底哪里听不懂，我相信你第一个反应肯定是“哦!原来是这个单词，怎么我听不出来呢” 这样带着疑问去看书会比单调地背有意思多了;最后，看着书本跟着录音模仿跟读。

英语口语练习方法十篇
【导语】提⾼英语⼝语需要养成⼤胆开⼝、认真听的习惯，还要给⾃⼰创造⼀个良好的学习环境以及养成快速阅读的能⼒。
不管是学习什么语⾔，都要求能够达到流畅的听、说、读、写的⽔平，英语的学习也不例外。
以下是⽆忧考整理的英语⼝语练习⽅法，欢迎阅读！1.英语⼝语练习⽅法 1、养成⼤胆开⼝的习惯 ⾸先要做的是消除⼼理障碍，⼤声说出来。
我们都知道，任何语⾔都是先有声⾳，再有⽂字的，如果发⾳不准确，别⼈就听不懂，所以想要学好英语，⼀定要⼤胆地开⼝说、开⼝读。
2、养成认真听的习惯 说的习惯是在听的基础上养成的。
听说结合可以快速地将单词和句⼦的⾳、形、义结合在记忆中。
学习⾳标，要注意观察⽼师的⼝型动作，然后⾃⼰学习，反复练习。
学习单词时，听⽼师朗读或跟着磁带朗读，尽量准确流利地发⾳。
不要⽤汉语来标记单词的谐⾳，这样记忆单词的效果不⼤。
3、创造良好的学习环境 试着去英语⾓和别⼈交流。
这样不但可以练习⼝语，还可以交流英语学习经验，开拓视野，提⾼英语学习兴趣。
如果找不到同学或者参加英语⾓的机会⾮常少，那么你可以利⽤其他⽅法来继续练习英语⼝语。
例如⼝语作⽂和5分钟强化训练法。
找好⼀个题⽬作⼀分钟的⼝语表达，同时将其录⾳。
4、经常速读 频繁快速的阅读，⼀⽅⾯可以锻炼⾃⼰的⼝腔肌⾁，提⾼灵活程度，另⼀⽅⾯也有助于掌握语感，使⾃⼰讲出⼀⼝流利的英语。
但快速阅读并不是⼀种孤⽴的能⼒，它必须基于⼀定的基础知识，⼀定的词汇和基本的语法，以及⼀些重要的阅读技巧。
2.英语⼝语练习⽅法 1、练习⽅法之演讲 练习⼝语的⽅法就是做英⽂演讲。
我们⽣活在⼏乎可以称得上是纯中⽂的环境，平时并没有练习英语⼝语的条件和机会，所以，⼤家需要多参加⼀些可以锻炼⾃⼰⼝语能⼒的活动，⽐如英⽂演讲⽐赛。
⼤部分演讲活动都是在⾼压条件下进⾏的，即使已经提前组织好了语⾔，也可能出现遗忘或是记错的情况，不过这种练习⽅法也是最锻炼⼈的。
2、练习⽅法之词汇量检测 英语单词是英语的基础，如果我们在演讲中只能⽤最简单的词汇来组织语⾔，那么会显得我们的整个演讲内容不够⾼级，甚⾄不够地道，很难得到较⾼的评价。
英语口腔后部发声训练方法
英语口腔后部发声训练方法你知道哪些唱歌的基本要领?那么你知道口腔后部发声法是什么?下面是店铺!小编我和你们一起去了解一下相关的资料吧，希望能帮助到你们!口腔后部发声法的基本知识对于我之前提到的‘口腔后部发声法’，很多朋友都表示感兴趣。
看我之前文章的朋友，应该记得，我是先自己看电视慢慢领悟出来。
还有一点我还没提过，那是，我在国外教学生汉语拼音时，外国学生发汉语拼音的特点是：一，声音浑厚低沉二，声音主要是在口腔后部形成，因为他们的语言都是使用口腔后部发声。
我自己概括是，他们好像是用嗓子眼说话。
那天，我教汉语拼音：d, t, n, l, g, k, h, 他们总发成英语的d, t, n, l, g, k, h。
我就模仿他们的声音念拼音，并告诉他们，那是英语，不是汉语拼音。
之后，我自己感受拼音的发音方法和发音部位后，突然的冒出一句：舌头整体往口腔前部移一点(其实是劲使在舌头前部)，再发声，这样出来的声音就像汉语拼音了，结果，学生试着这样发声，声音效果确实像汉语拼音了。
下课后，我突然感觉茅塞顿开。
那么，说英语，要是把舌头整体往口腔后移(劲使在舌头后部)，是不是出来的声音也就像欧美人的声音了。
就这样，才有了我看电视发现“口腔后部发声法“的那一幕。
大家最最关心的是怎么练。
其实，我也是摸着石头过河的感觉。
因为这是舌头在起重要的作用。
那么，我先跟大家打打比方吧，然后，大家想想，自己慢慢感受，试着去练习。
大家都知道，感冒的时候，说话声音低沉，沙哑，那时候，你说出来的英语肯定比你正常时候好听。
说汉语，就像是音乐里中国的民族唱法，说英语，就像是美声唱法。
民歌，声音又尖又高，声音从舌尖和嘴唇那部位出来的;而美声，则是浑厚，从口腔后部和喉部出来的声音。
现在，我想让大家试一试：您现在试用一下民族和美声的唱法唱“啊---------”，感受一下是不是声音明显的不同，舌头的位置也是放在不同的位置!(我自己概括:舌头往后移了，这也是大家很迷惑的地方，都觉得舌头怎么能后移呢，哈哈哈。

These is also great variation in each individual’s response to treatment and this can, on occasions, affect the final result.RiskAs with any form of treatment there are some risks associated with orthodontic treatment. While every effort is taken to minimize these risks, you, the patient, can help to minimize them by following treatment advice carefully and fully.1. Tooth decay and enamel damageTooth decay and enamel damage can occur if sugary or acid foods are eaten and tooth brushing is not maintained at a high standard. This damage can occur at any time but is more likely when fixed appliances are attached to the teeth.2. Root resorptionOrthodontic tooth movement involves light pressure being placed on the teeth and roots. In some patients changes such as root shortening may occur. The causes of this are not well understood and it is not always possible to identify susceptible patients in advance. In the majority of cases where this occurs there are so significant consequences.3. HeadgearIf not worn correctly, headgear may cause injury. It is imperative that the written instructions are necessary when using a headgear appliance.4. Joint discomfortSome individuals may experience jaw joint discomfort during orthodontic treatment. This is usually a transitory phase and indeed such symptoms also occur in patients who are not wearing orthodontic appliances.5. Post–treatment changesThroughout life the position of teeth alters regardless of orthodontic treatment.Some aspects of orthodontic treatment are particularly prone to post–treatment changes.Following fixed appliance treatment retainers will need to be worn. There are other changes, particularly the degree of crowding of the lower incisors, that may progressively alter throughout life.6. Medical historyGeneral medical pro blems may influence an individual’s response to orthodontic treatment. It is important to inform your orthodontist of any changes in your medical health.Instructions for Patients Wearing Fixed AppliancesYou are now wearing a fixed appliance. You must take great care it.You must:1.Clean your teeth with a brush, immediately after every meal and before going to bed. If yourteeth are not kept clean damage will occur.2.Avoid eating hard foods (such as crusty bread), and sticky food(such as toffee and nougat).3.Since it will be necessary to use a toothbrush after eating, most patients find it best to avoidsnacks taken between main meals.4.Contact the orthodontist if the appliance hurts, becomes loose, or if any part however small isbroken.5.Continue with your routine dental visits.Initially there will be some difficulty in eating and speaking but this will soon pass.You may experience some discomfort for a few hours following the placement of new archwires. This may be eased with a mild analgesicQuestion:1. The orthodontic treatment may have good effect on a person except (C)A. maintaining good oral healthB. improving a person’s face appearanceC. ensuring every individual patient to have the same attractive smileD. making teeth easier to keep clean2. What would doctors advise on the procedure of orthodontic treatment? (B)A. Eat sugary or acid foods and maintain tooth brushing at a high standard.B. Conform the instructions when using a headgear appliance.C. Be scared by root resorption and joint discomfort.D. Wear retainers irregularly after fixed appliance treatment.3. When will the tooth decay and enamel damage happen? (C)A. only when eaten too many sugary or acid foodsB. when tooth brushing maintained at a high standardC. the damage can occur at any timeD. especially when flexible appliance are attached to the teeth4. What kind of food can you eat when you are now wearing a fixed appliance? (D)A. crusty breadB. toffeeC. nougatD. orange5. Which of the following statement in not true? (B)A. Clean your teeth immediately after you have a meal.B. You can repair it by yourself when the appliance is broken.C. You should avoid eating hard food.D. Contact your dentist if the appliance becomes loose.TEXT 2So far we have discussed mostly about the dental profession and society. Now we will look at dentistry as a possible profession for you.Can you answer "yes" to the five questions below? If so, you have passed a simple, but very important, test --a sort of entrance requirement for dental school.Are you skillful with your hands?Do you like to work with people?Is your health good?Does science interest you?Would six years of college be alright with you?Let us look at the first four questions right nowClever Hands. To even get into dental school, you must pass a test of "manual dexterit". A dentist must use his hands skillfully in very small spaces, and use them with controlled strength and gentleness.If you are very good at precise, detailed work with your hands --and like such work -- but cannot answer "yes" to the other questions.Working With People. Many people choose dentistry because they do not like to work for other people, but want to be their own boss. Working with people is, of course, something quite different. Dentists work with people under very difficult conditions every day. They need patience to put up with a patient's needless worries. They need calm to match his anxiety. Dentists must also have sympathy -- or at least a sympathetic manner -- like a physician's "bedside manner".Suppose you do not like taking all these pains with people. You could still enter dentistry if you chose a proper specialty. For instance, oral surgeons and oral pathologists have very little contact with patients. Dental teachers need to communicate with people, but in a much more relaxed way. If you are solitaryminded, you could be a research scientist.Good Health. Dentists stand on their feet a lot. They often work in awkward positions. They need a lot of stamina. Robust general health is a prime requirement for dentistry.Dentists need particularly good eyesight. This does not mean that you cannot wear glasses. With or without glasses, you have to identify some very small changes and very tiny structures in some corners that are difficult to see.The Scientific Mind. Do you like the science courses you have had in school? Do you enjoy the science columns and features in the news magazines?Good grades in all your subjects are important. They show that you have two qualities that you may get into dental field. Those qualities are intelligence and persistence.1. what would be the best title for the text? CA. A Test for CollegeB. Features for College StudentsC. Is Dentistry for YouD. The Benefits of Good Healthy and Skillfull Hands2. It is indicated in paragraph 2 that___. DA. the five questions are a test of every dental schoolB. if you say "yes' to the five questions you will be a dentistC. if you say "yes' to the five questions, you will get an entrance for a dental school that you wantD. the five questions are a simple ,but very important test for students who want to go to dental school3 dentists don’t have to possess _____ BA skillful handsB pass all the testsC good healthD group spirit4 which one is wrong according to the text? AA I wear glasses so I can’t be a dentistB dentistry is related to scienceC to be a dentist need intelligence and persistenceD not all people is suitable to be a dentist5 The word “stamina” is closest in meaning to ______. Bknowledge B endurance C characteristics D muscle翻译The pulp. The pulp consists of loose connective tissue and carries the blood, lymphatic and nerve supply to the tooth. Where it meets the dentine ,the surface of the pulp is covered by a layer of odontoblasts. These are columnar cells with oval nuclei, and each cell has a process that lies within a corresponding tubule in the dentine. Immediately internal to the odontoblast layer there is a narrow cell-free zone.Dentine. Physically and chemically dentine is very similar to bone, consisting of 30 percent organic material. As in bone ,the organic fraction consists of collagen fibrils embedded in a mucopolysaccharide cementing substance, and the inorganic fraction consists mainly of calcium phosphates in the form of apatite crystals. Unlike bone ,however, dentine contains no cell bodies but only cell processes, those of the odontoblasts ,in the dentinal tubule .The dentinal tubules are 2to3 um diameter and each runs through the whole thickness of the dentine from the cell body of the odontoblast to the surface of The dentine. There are cross-communications between the tubules, containing anastomosing branches of the odontoblast processes. Where calcification is incomplete, the separate globules can be seen, with the uncalcified or hypocalcified ground substance in between them. Such areas are referred to as interglobular dentine.Enamel. Mature enamel can be studied only in ground sections unless special methods are employed, since it is completely removed by routine histological decalcification. The inorganic material is an apatite and small organic fraction is mainly of keratinous nature. Enamel consists of rods or prisms in an interprismatic substance that is slightly less mineralized than the rods themselves. Each rod runs from the enamel-dentine junction through the whole thickness of the enamel to its surface, following a slightly wavy course. The rods have a “fish-scale” appearance in cross-section, with an average diameter of 4 um.牙髓。

就像跑步必须快速才能起到锻炼肌肉的作用一样，“最快速”使你的口腔肌肉得到“强行的刺激和锻炼”，“落后、僵硬部分的肌肉”变得灵活，而且因为语言是连贯的，不是一个字一个字独立“蹦”出来的，所以“最快速”还能帮助你形成说英语的连贯性，该省略的要省略，该连读的要连读。
{疯狂对象}
一切实用的句子、段落、短文、文章。
{疯狂场所}
洗手间、阳台、厨房。
学生最好在操场和树林，顺便赶走幽会的人。
{疯狂时段}
早中晚！走路的时候，等车、坐车和堵车的时候！失恋的时候！只要卡
片随身带，随时随地都可以进行“三最”操练。
{疯狂标准}
“三最”之后，要达到脱口而出，并能够中英文自由转换！口译笔译不在话下！这是验证英语水平最好的“试金石”。
{疯狂目标}
把中国肌肉锻炼成国际肌肉。
把亚洲人脆弱的薄脸皮锻造成欧美人天真的厚脸皮。
{疯狂比赛}
每次记录时间，争取打破（break）上次成绩，这样更加刺激！
{疯狂手段}
第一，可以在舌面上放上硬的水果糖（1，3-4块不等）。
第二，在上下齿之间咬上一枚硬币、牙签、筷子或其它的类似物。
这样可以强行发展口腔肌肉，早日达成地道美语“信口开河”！
第三，不需要道具的方法：咬住上下牙齿，“咬牙切齿”地说美语，几天之后就会发现你不再是用中国嘴唇而是用美国口腔肌肉来说话了，绝对有效！
学习外语就是训练（train）口腔肌肉，使之轻松地发出陌生的（strange；unfamillar）外国声音，变成灵活的国际肌肉；学习外语就是苦练脱口而出！只有这样才识真正地拥有语言！。
