(单词翻译:单击)

一、单元综述:


本单元重点是张大嘴巴跟老师一起读,感受美语。练习我们的脸部肌肉,并体会美语发音的方式和技巧。

二、 美语发音:


1、4个双元音


美语音标最大的区别在于其中的元音,过去学过的元音是单元音,但美语中所学的是双元音


1){e}-{ei}


age, game, day
sentence: More haste, less speed.欲速则不达
第一步把每个音发准
第二步加上声调
练习: It’s pay day today 今天是发工资的日子

2){o}-{ou}结尾停在u


boat, note, so
美语发音的特点:尽量在口腔的后部把音发出来。
sentence: I hope so.
练习:He posed for a group of photo with his old fellows.
注:美语中常常对a和the进行变音,目的是为了强调
eg:
This is the best opportunity we ever have to enter the market.

3) {a}-{ai}


bike, mine, flight
this bike of mine
sentence: All right.
注:all不要卷舌
练习:Out of sight, out of mind 眼不见,心不烦

4) how


out, now about
sentence: Let’ s get out of here.
It’s kind of tough.
It’s kind of torture to read mathematics everyday.
练习: This is out-and-out power politics. 这是彻头彻尾的强权政治


2、2个后元音


1){半圆两点}


发音技巧:尽量往最里吞这个音
not, bottle, hot, job, hospital
sentence: It’s a promise.
练习:little red lorry 红色小卡车

2){u}


good ,book, should
sentence: She’s looking at a good book.
更多例子: new  student  attitude  due
I am for this position.

3、辅音t的发音
writer, letter, better, city,

发音变化一:浊化

浊化原则1:t处在非重读音节要浊化
如:writer, letter, better, city,

浊化原则2:t处在重读音节不能浊化
如:Italian, attack, atomic, Latino, photographer

浊化对比:
Italy, attic(阁楼)
atom(原子), Latin, photograph

发音变化二:t在词组中的发音变化:
练习:pick it up
I got it.
right away


发音变化三:t发音的特殊情况:


当t发的很快,就会变成n的音
internet
interview
interesting
representative

发音变化四:失去爆破
right now, just now

发音变化五:t的音从鼻子里出来(美音,英音都有的一种特殊情况)
Britain, mountain, fountain 

4、r的发音


1)r在单词中的发音


练习: Rolly rolled a round roll around the road.
spare, burglar, dirty, porch, more

2)r带动后面元音的发音


world  girl  pearl
The girls are the pearls in the world.

原则:只有字母r存在才能卷舌
经常发错的音:China, America, idea
