练习材料：Lesson 72 A car called Bluebird 时长：98s
The great racing driver, Sir Malcolm Campbell, was the first man to drive at over 300 miles per hour.

He set up a new world record in September 1935 at Bonneville Salt Flats, Utah.

Bluebird, the car he was driving, had been specially built for him.
ˈbluː bɜːd, ðə kɑː hiː wɒz ˈdraɪvɪŋ, hæd biːn ˈspɛʃəli bɪlt fɔː hɪm.
It was over 30 feet in length and had a 2500 horse-power engine.

Although Campbell reached a speed of over 304 miles per hour, he had great difficulty in controlling the car because a tyre burst during the first run.
ɔːlˈðəʊ ˈkæmb(ə)l riːʧt ə spiːd ɒv ˈəʊvə θriː ˈhʌndrəd ænd fɔː maɪlz pɜːr ˈaʊə, hiː hæd greɪt ˈdɪfɪkəlti ɪn kənˈtrəʊlɪŋ ðə kɑː bɪˈkɒz əˈtaɪə bɜːst ˈdjʊərɪŋ ðə fɜːst rʌn.
After his attempt, Campbell was disappointed to learn that his average speed had been 299 miles per hour.

However, a few days later, he was told that a mistake had been made.
haʊˈɛvə, ə fjuː deɪz ˈleɪtə, hiː wɒz təʊld ðæt ə mɪsˈteɪk hæd biːn meɪd.
His average speed had been 301 miles per hour.
hɪz ˈævərɪʤ spiːd hæd biːn θriː ˈhʌndrəd ænd wʌn maɪlz pɜːrˈaʊə.
Since that time, racing drivers have reached speeds of over 400 miles an hour.
sɪns ðæt taɪm, ˈreɪsɪŋ ˈdraɪvəz hæv riːʧt spiːdz ɒv ˈəʊvə fɔː ˈhʌndrəd maɪlz ən ˈaʊə.
Following in his father's footsteps many years later, Sir Malcolm's son, Donald, also set up a world record.
ˈfɒləʊɪŋ ɪn hɪz ˈfɑːðəz ˈfʊtstɛps ˈmɛnijɪəz ˈleɪtə, sɜː ˈmælkəmz sʌn, ˈdɒnəld, ˈɔːlsəʊ sɛt ʌp ə wɜːld ˈrɛkɔːd.
Like his father, he was driving a car called Bluebird.

知识笔记：/v/
1）上齿轻触下嘴唇，发音和/f/口型基本相同。
2）气流从口腔通过唇齿间的缝隙，引起摩擦。
3）同时声带震动发出声音，送气力量较弱。
tyre burst 爆胎
L2点评：
@[000]卫芳-北京 您好~听了您的朗读，觉得是不是还对文章不够熟悉？一个很明显的错误是hundred 的后半部分 drəd 读成了 dri:d ，还有reached 那里读成了reach，建议可以再练习一下/æ/的发音，听起来had 和flats 的/æ/发的不一样，不太稳定。
@[015.48]践行-云南-IT 您好！听了您的朗读~觉得您的重音给的很明显，断句很棒~然后有一个问题是per 的元音部分ɜː发成了e。
@[000]月映沙丘-武汉-交通 您好~听了您的朗读，和我一样也是v的部分不够明显，driver 的后半部分er 听起来读成了al ，/ə/的音没有发出来， 然会hundred 的drəd 读成了 dri:d 。
收到的点评:
@［00］ziq 西安 学生 你好，听了你的朗读，比较明显的问题是V跟th的音都没有发到位，还有great双元音不明显，world中L音不清晰
练习感悟：
今天被点评了之后又反复听了自己的录音，发现record 的读音好像读成了美音，但我要练习的应该是英音。
这几天懈怠的有点多，要重新提高标准了。
