Lesson48 Did you want to tell me something?
Dentists always ask questions when it is impossible for you to answer. My dentist had just pulled out one of my teeth and had told me to rest for a while. 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. He then asked me how my brother was and whether I liked my new job in London. In answer to these questions I either nodded or made strange noises. Meanwhile, my tongue was busy searching out the hole where the tooth had been. I suddenly felt very worried, but could not say anything. 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.

(3) 学音标/g/
1) 嘴巴张开,将舌后部隆起，紧贴软腭，憋住气。
2) 然后舌后部迅速降低，使气流冲出口腔。
3) 同时声带震动发出声音，送气力量较弱。
/g/是个浊辅音，声带震动发声。注意不要用汉语拼音中的"g（哥）"来代替,汉语拼音的g是口腔发音，音标是声带震动发音。
4) 单词练习
a、字母及字母组合g,gg通常发/g/音,例词：
game /geɪm/ n. 游戏
glade /gleɪd/ n. 林间空地
girl /gɜːl/ n. 女孩
luggage /'lʌgɪdʒ/ n. 行李
beggar /'begə/ n. 乞丐
golf /gɒlf/ n. 高尔夫球
b、字母组合"gu"或"gh"通常也发这个音，它们可以出现在元音前，与元音构成一个音节,例词：
catalogue /'kæt(ə)lɒg/ n. 目录
rogue /rəʊg/ n. 流氓
ghost /gəʊst/ n. 鬼
