Lesson48 Did you want to tell me something?
Dentists always ask questions when it is impossible for you to answer.
ˈdɛntɪsts ˈɔːlweɪz ɑːsk ˈkwɛsʧənz wɛn ɪt ɪz ɪmˈpɒsəbl fɔː juː tuː ˈɑːnsə.
My dentist had just pulled out one of my teeth and had told me to rest for a while.
maɪ ˈdɛntɪst hæd ʤʌst pʊld aʊt wʌn ɒv maɪ tiːθ ænd hæd təʊld miː tuː rɛst fɔːr əwaɪl.
I tried to say something, but my mouth was full of cotton-wool. He knew I collected match boxes and asked me whether my collection was growing.
aɪ traɪd tuː seɪ ˈsʌmθɪŋ, bʌt maɪ maʊθ wɒz fʊl əv ˈkɒtn-wʊl. hiː njuː aɪ kəˈlɛktɪd mæʧˈbɒksɪz ænd ɑːskt miː ˈwɛðə maɪ kəˈlɛkʃən wɒz ˈgrəʊɪŋ.
He then asked me how my brother was and whether I liked my new job in London.
hiː ðɛn ɑːskt miː haʊ maɪ ˈbrʌðə wɒz ænd ˈwɛðər aɪ laɪkt maɪ njuː ʤɒb ɪn ˈlʌndən.
In answer to these questions I either nodded or made strange noises.
ɪn ˈɑːnsə tuː ðiːz ˈkwɛsʧənz aɪ ˈaɪðə ˈnɒdɪd ɔː meɪd streɪnʤ ˈnɔɪzɪz.
Meanwhile, my tongue was busy searching out the hole where the tooth had been.
ˈmiːnˈwaɪl, maɪ tʌŋ wɒz ˈbɪzi ˈsɜːʧɪŋ aʊt ðə həʊl weə ðə tuːθ hæd biːn.
I suddenly felt very worried, but could not say anything.
aɪ ˈsʌdnli fɛlt ˈvɛri ˈwʌrid, bʌt kʊd nɒt seɪ ˈɛnɪθɪŋ.
When the dentist at last removed the cotton-wool from my mouth, I was able to tell him that he had pulled out the wrong tooth.
wɛn ðə ˈdɛntɪst æt lɑːst rɪˈmuːvd ðə ˈkɒtn-wʊl frɒm maɪ maʊθ, aɪ wɒz ˈeɪbl tuː tɛl hɪm ðæt hiː hæd pʊl daʊt ðə rɒŋ tuːθ.
录音时长：1m2s（1m3s）
任务配置： L0+L1+L3+L4
知识笔记：
/θ/（bbc音标视频con_voiceless_6）
1）舌尖微微伸出，置于上下门齿之间，舌身成扁平。
2）气流由舌齿间泻出，摩擦成音，舌尖和下齿之间的气流通道非常窄小，气流从舌齿间的窄缝中泄出。
注意：/θ/是个清辅音，声带不震动。要注意与/ð/,/s/,/z/的区别，发这个音主要是舌尖与上齿之间的摩擦，所以千万不要紧紧咬住舌尖，应该是上齿轻触舌尖。
anything/ˈɛnɪθɪŋ/ teeth/tiːθ/ something/ˈsʌmθɪŋ/ mouth/maʊθ/
单词：tooth（单数）teeth （复数）
练习感悟：
1./θ/这个音哦，我一直咬舌太紧，以致于气息出不来，所以发音很难受，今天才发现，你说气不气人。气死我了哈哈哈哈。
2.最近一直休息不好，今天六点睡了会儿，精神好多了，也有精力把134一起做了。真的，以后太累还是得休息不能硬撑。
3.今天的朗读是半蹲着读的，效果很好！不过因为腹部力量不足，声音有点抖，录音里可能听不出来，但我自己是觉得在控制气息上有些费力。这个方法很棒，明天继续尝试。
4.加油~
