php怎么记录cook,如何学习音标?

音标是学习英语的第一步,想要学好音标需要认识音标、会读音标,这样以后才能认识单词。在学习音标前,我们要先知道国际音标有48个,元音有20个,辅音有28个,元音又分为单元音和双元音,单元音有12个,双元音有8个。

音标数目

在上表中,我们可以看到音标有48个,现在我们常说的国际音标也是48个。

元音部分

辅音部分

音标的分类

最实用的分类方式是:元音=长元音+短元音+双元音;辅音=清辅音+浊辅音。

英语一共有48个国际音标,包括20个元音,28个辅音。

20个元音包括5个长元音:/i:/、/ɜ:/、/u:/、/a:/、/ɔ:/;

7个短元音:[i] [ə] [ɔ] [u] [ʌ] [e] [æ];

8个双元音:/eɪ、/aɪ/、/ɔɪ/、/ɪə/、/eə/、/ʊə/、/əʊ/、/aʊ/;

注意:

1、长元音顾名思义就是发的音比较长而饱满;短元音则发的音比较短而急;

2、双元音就是两个单元音拼在一起,成为组合音。双元音发音的特点是前面的单元音发音长,后面的发音比较短。

28个辅音包括:轻辅音/p/ /t/ /k/ /f/ /θ/ /s/ /ʃ/ /ts/ /tʃ/ /tr/ /h/

浊辅音 /b/ /d/ /g/ /v/ /ð/ /z/ /ʒ/ /dz/ /dʒ/ /dr/ /r/

鼻音 /m/ /n/ /ŋ/

半元音 /j/ /w/

边音 /ǀ/

5个长元音/i:/、/ɜ:/、/u:/、/a:/、/ɔ:/发音技巧。

(1)/i:/发音技巧:

发音时舌尖抵下齿,口形扁平。在发音的时候要尽量拉长,就像古人喝醉酒以后吟诗的感觉。

单词举例:bee [biː] n. 蜜蜂;see [siː] v. 看见,参看

(2)/ɜ:/发音技巧:

/ɜ:/是长元音,近似于北京腔的“儿”话音,如“花儿”的“儿”。发好这个音,关键在于卷舌!

单词举例:shirt [ʃə:t] n. 衬衫,男士衬衫;nurse [nə:s] n. 护士,保姆

(3)/u:/发音技巧

发这个音时双唇用力向前突出,有点像拉长了音说“乌”,但要注意,“乌”的口形较扁。

单词举例:moon [mu:n] n. 月球,月亮;room [ruːm] n. 房间,空间

(4)/a:/发音技巧

发音时口张大,双唇稍收圆。发音时可以照着镜子,说“啊”,看看嘴巴张得够不够大,记得要将嘴巴尽量张大。

单词举例:ask [a:sk] v. 问,询问; far [fa:r] adj. 远的

(5)/ɔ:/发音技巧

发这个音时,双唇稍稍收圆,并向前突出,发音接近于汉语“嗷”。这是个长元音,记住:长元音一定要拉长,发出来才好听。

单词举例:door [dɔ:r] n. 门; short [ʃɔ:t] adj. 短的

学习步骤

抄写

抄写音标,并了解音标特点。

对音标的基本认知

1、区别长短音带“:”的音标发音相对较长不带“:”的音标发音相对较短。

2、区别清辅音和浊辅音核心区别:清辅音声带不震动,浊辅音声带振动。

模仿练习

找合适的视频学习学习跟读。例如b站上《【赖世雄48个英语音标朗读示范,美音英音对照版-哔哩哔哩】 【https://b23.tv/sHYQFZ3】》、《【李咏梅老师英语(音标部分)——最牛的初中英语老师!没有之一!李咏梅国际音标 (完整版发音篇)-哔哩哔哩】 https://b23.tv/U1pmjNE》、《【纯正英式发音】这是BBC出品的到现在为止最棒的英语发音教程(完整版)-哔哩哔哩】 https://b23.tv/gZzDKl5》,以上几个视频都非常不错,详细讲解每个音标的读法。注意视频一定至少跟读5遍,才能确保你的学习效果。

也可以通过下面这个视频观察发音口型的变化。

《【48个英语音标示范读音-哔哩哔哩】 https://b23.tv/mt9vVaK》

1、模仿练习,学习国际音标的发音,要注意观察老师的口型,观察发音部位的变化,主动模仿发音,初学可以对着镜子模仿练习,特别是元音发音的舌位高低,口腔开口度大小与音色关系十分密切,可以通过镜子观察口型上的区别,观察舌尖、舌面、舌叶的活动情况,比如u和o、i和e、e和ε等等,掌握准确口腔开口度,对于准确发音具有非常重要的意义。

2、听音训练:学习国际音标需要认识48个音标,通过反反复复的听力练习,达到强化记忆。听音训练,如果有条件,可以多听老师朗读音标,也可以使用录音带反复听音,本课件中的每个音素,都可以循环倾听,强化记忆。

3、多动口,动口是加强实践的关键和核心,听音也好,模仿也好,比较也好,最终要归结到自己发音这一目标上来,所以勤动口是掌握国际音标发音的关键。俗话说,"三天不写手生,三天不念口生",说的就是要加强动手动口能力的培养。因此学习国际音标,要时时加强语音训练,勤动口,反复实践练习,在实践中比较,在实践中体会差别,做到熟能生巧,这样自然就掌握国际音标的发音了。

重点音标讲解

单元音

[i:] =“一”

[ɪ]:[ɪ]开口要比[i:]稍大,注意比较两图口型。

[e] 嘴张45°,[æ]嘴张90°

[ɜ:r] [ər]=“二”

[ə]=额(不卷舌)

[ʌ]:开口比“啊”略小

[ɑ:r]=卷舌的“啊”

[ɑ] =“啊”

[ɔ] =开口稍大的“哦”

[ɔ:r]=卷舌的“哦”

[u:]核心:双唇由半开微突,过渡到合嘴圆唇

[ʊ] 发成噘嘴的[ə],气流向外。

双元音

双元音较简单,大多数可进行类比,注意双元音的重音在第一个音标,即前一个音读的稍重,后一个音读的较轻。

[eɪ]=“A”

[aɪ]=“I”

[əʊ]=“O”

[ɔɪ]=“哦一”

[ɪə]=ear

[eə]=air

[ʊə]=“乌尔”

辅音

大部分辅音跟“汉语拼音”都有相似之处,直接看视频模仿即可,这里只讲解易错发音。

爆破音:

[t] [p] [k] 不要读成[tə] [pə] [kə] 注意:它们声带不震动

摩擦音:

[f][v] 咬唇音,注意上齿咬下唇

[θ][ð]

上下齿轻咬舌头,发音时能看到你的舌头露出

[ʃ]=不发音的“诗” [ʒ]= “日”

[r]=撅嘴+卷舌的“热” [h]=不发音+舌头平放的“喝”

鼻音

[m] 合嘴

[n] 舌前部抵住上颚

[ŋ] 嘴巴张开

舌侧音[l]

元音前:跟拼音“l”发音一致元音后:发“l”的前半段

半元音

[j] “也”

[w] =圆唇噘嘴的“我”

破擦音

[tʃ]= 不发声的“吃”

[dʒ]= “居”

[ts]=不发声的“次”

[dz]=“子”

[tr] 先发“t”,在发“r”,最后结合在一起

[dr] 同上

词汇拼读

1、规划拼读任务,拿出单词书或课本词汇表,找只含1~2个音节的单词拼读,20个为一组,每天练习3组,当然如果有时间,多进行几组也OK,加强效果。后期难度逐渐加大。

2、输入法识别词汇,每拼读一个词汇,都对着X飞输入法的语音识别功能朗读,看能否被输入法识别出单词,用机器来检测是否读的准确。

3、听词汇跟读,不管输入法识别出单词,还是没识别出单词,都要查手机字典,来听一遍听力,并跟读,模仿语调和轻重读音。

例如:Cash driver apartment money breakfast lawyer agency

学习计划

1、国际音标,一共48个,每天学4个,12天学完,元音和辅音每天各学习两个。

2、学完以后结合和音标相关的单词,每天坚持读一个小时,第二天要把第一天的一块儿读,第三天要把前两天的一块儿读,依次类推,坚持学完所有的音标,就可以读字典上任何一个单词。

3、长期坚持下去,会发现其实很多字母和音标有着关联,比如ph都发音标f的音,字母u发尖a的音,类似的规律,当大家坚持下来以后会发现很多,同时你甚至可以听到单词的发音就能把单词拼出来,直接就把背单词的问题解决了,音标会读,单词会读,单词会背,听力当然也不再是问题。自己总结出来的规律说明真的学会了,同时自己得出来的结论要比老师直接告诉你印象更深刻,同时最重要的是用起来更容易。

注意事项

1、了解发音要领,模仿老师口型

学习语音,一定要注意口型,并仔细揣摩每个音标的发音要领,特别是相似音标的发音区别。

零基础学员不要以为盯着老师的口型就好了,其实发音很多都是内部器官看不到的, 所以需要老师正确的发音示范,跟着老师一起读,然后再加上老师给的一些技巧,继续跟读,老师感觉哪有问题,再帮着纠正,这样一系列过程才是练成标准发音的秘籍。

2、 单词拼读实战,一对一纠正错误

养成一口纯正口语最重要的还是练习练习再练习,单词拼读实战训练,巩固你的发音。不断读,不断纠正,训练单个音标到训练多个单词,在学习语音的过程中,再掌握一些基础的词汇。

3、辩音练习,纠正错误,掌握发音规律

训练难度会随着课程的深入不断加强,但还是训练相同的内容,一节课很多类似的训练内容。音标中很多类似的发音,将相似音放在一起对比再练习,舌头和耳朵在这很重要。

为什么针对小孩子的编程课突然间这么流行?

少儿编程的热度,我相信所有家长都能感受到。不确定要不要“赶这个时髦”的家长,不妨来了解一下,儿童编程课为什么会突然流行起来。

这场风潮,来自英国和美国。

英国

Simon Peyton Jones是英国儿童编程浪潮的发起人,也是剑桥微软研究院的计算机科学专家,现在成为了英国国家计算机教育中心的负责人。

2007年的某一天,他突然发现,自己的孩子们虽然都会用电脑,却完全不知道电脑运转的原理。孩子们并不知道,他们常用的软件是怎么被做出来的。而且孩子在学校上的电脑课,与他工作中接触的计算机科学,完全没有关联,早已过时。

Simon认为,不会编程的孩子,长大以后会被懂编程的人牵着鼻子走。

于是,他创建了一个社区组织,“学校里的编程课(computing at school)”,在英国的中小学里推广。希望将传统的学习word、excel的电脑课,替换成实用的编程课,并且讲解计算机运行的原理、培养孩子们的计算机思维。

很快,英国教育局将编程课纳入了国家教学大纲。目前,根据BBC提供的数据,英国有13万中小学生,在学校里学习编程。

美国

美国的少儿编程浪潮,背后的主要推手是一家叫做code.org的编程教育机构。该机构先后得到了微软、脸书、谷歌、Salesforce等超过6000万美元的投资。code.org用这笔钱,推动了美国二十四个州的教育改革、给全世界超过一亿名学生提供了免费编程入门课、对将近6万名老师进行了编程教育培训。

连当时在任的奥巴马总统,都帮他们宣传编程课。

code.org创办于2012年,创始人是一对双胞胎兄弟,Hadi Partovi 和 Ali Partovi。Hadi是Facebook和Airbnb的天使投资人,Ali是Zappos和Dropbox的天使投资人,可见两兄弟在硅谷的地位。他们现在的目标是,让美国的每一所公立学校都有编程课。

Partovi兄弟幼年跟随父母,从伊朗移民到美国。两个人都考上了哈佛大学,获得计算机科学的学士及硕士学位,从此改变了自己和家人的命运。他们希望现在的小孩,也有机会接触到编程,像他们一样获得成功。

2013年,code.org做了一个病毒式传播的网红视频。邀请了比尔.盖茨(微软创始人),马克.扎克伯格(Facebook创始人),杰克.多尔西(Twitter创始人),德鲁·休斯顿(Dropbox创始人),克里斯.波什(NBA球星)等人出镜,讲述他们是如何学编程的,以及为什么现在的孩子应该学编程。

在YouTube播放一周后,该视频就达到了900万的观看量。自此掀起学习编程的热潮,各种编程机构便如雨后春笋般涌现出来。

目前,根据code.org提供的数据,美国有3600万中小学生,在学校里学习编程。

除了编程教育机构,各大科技公司也在开发自己的编程教学大纲。比如说苹果,开发了免费编程软件Swift Playgrounds供孩子们学习;在全世界的苹果店里开设免费编程课,由工作人员使用Swift Playgrounds开展教学;并且在苹果网站上,也提供了很多供老师使用的教学素材。

苹果CEO,Tim Cook,还在去年的“白宫科技巨头聚会”上发言表示,“编程是现代社会非常稀缺的技能”;并给特朗普总统提建议,“编程课应该成为每一所公立学校的必修课”。

对于少儿编程浪潮的质疑

当科技公司大佬们都在推动少儿编程的时候,不禁让人怀疑他们的动机。

code.org的创始人也承认,“如果你经营过一家科技公司,就知道招聘到、并留住好的工程师有多难”。按照扎克伯克的话来说,Facebook的招聘原则就是,优秀的工程师我们都要。

特朗普政府收紧的移民政策,让外聘程序员更加困难,也促进了本土编程教育的发展。

另外,还有说法认为科技公司推动少儿编程,是为了向学校售卖自己的硬件、软件产品,以及推广自己公司开发的编程语言。

《纽约时报》称,美国的中小学售卖硬件、软件产品的市场,在2020年预计可达到210亿美元的市场价值。比如说苹果的Playground软件最适合在iPad上使用,能够一定程度上促进iPad的销售。

至于编程语言,为爱达荷州制定编程教学大纲的甲骨文公司,的确主要教授的是该公司开发的编程语言Java。不过,Java也的确是行业内运用广泛的语言。

总的来说,对于少儿编程最大的质疑是,为什么我们要拿孩子的教育,去为科技行业的发展买单。

关于少儿编程浪潮的思考

面对编程热,我们要冷思考。不盲从,但也不要急于否定。

编程可以改变孩子的命运,让他们成为下一个比尔.盖茨吗?我想未必,毕竟成为比尔.盖茨是一个小概率事件。

编程可以培养孩子的逻辑思维、拥有计算机思维吗?我想是肯定的,虽然我们无法预测,自己家的孩子会如何把这种思维运用到ta未来的生活、工作中。

编程会成为和看书、写字一样重要的技能吗?我想也未必。每个人都懂一些编程,应该是21世纪的技能需求,因为各行各业都会涉及到代码;可是每个人都像看书、写字那样精通,应该是不需要的。

我小时候常常质疑学校对学科的选择,“我将来又不会去测量木块下滑的速度,为什么要学物理”。我想大家都有过这样的想法吧。

而现在少儿编程在做的就是,让我们重新思考孩子应该学习什么样的科目,是否应该把计算机科学加到孩子们的课表里。

学校里的科目,应该教给孩子们一种看世界的方式、一些解决现实问题的方法论、并且随着时间推移该学科不会消失。计算机科学这门课,都完全符合这些要求。特别是在未来的人工智能时代,科技渗透到人类生活的方方面面,这个学科会越来越重要。

在中国的中小学开设编程课之前,家长们可以让孩子不出家门,在网上学习、接触编程。介于编程语言大多基于英语,学习编程的同时,也得学习英语。
