Those who grow up is worried. 　
　　So my child 's sound in the class worthwhile beautiful.You listen ,When read the text , the most resounding of sound ,That certainly is I ;When class of music sings ,Man student the most beautiful of voice ,Certainly is I ;Suitable for reading aloud of Physical education wailed the most with great energy son ,That certainly is my …。…。At that time ,I is really very proud of myself having so a pair of good voice ,But now.-- 　
　　During Chinese class ,You again out of hearing I exceeded a lot of of the sound than others ;During class of music ,I sing always than others low 8 degrees ;During Physical education ,Though I shout shout oneself hoarse ,But you heard is only one."Boss duck."Voice in very yell.Perhaps you can ask ,What is the matter son ?Very simple ,I changed the voice. 　
　　According to reason say ,Change the voice is a normal phenomenon of physiology ,Men and women gives birth to and come to puberties can change the voice ,But but I very is not used to.I change voice than other schoolmates become early a lot of ,Schoolmate s in our class nearly didn't change ,And but I led once."Tide.",Although schoolmates have not so and too much."Pay close attention to."I ,But I frenqent cover up my voice consciously ,Dare not make a big clamor.If my voice is only to become more and more deep ,It isn't a evil deed to fall ,Perhaps like that schoolmates can say ：。"Yu ,When does your voice become so experienced ?"It is a pity that my voice just becomes more hoarse 、。Rough voice thick air ,Even some half overcast not sun.So tell word come ,Not only others heard at adds ,Itself feels oppressed too.What way may have again ?So a pair of voice ,Only himself and everybody endured. 　
　　All right ,Change the voice and let me so worried !
