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
