第四十六章 寓教于练

青少年一般是在13—16岁之间开始变声，大约需要历经一年的时间。龙腾小说网ltxsba.com变声期间的主要表现特征有：声音嘶哑、音域狭窄、发音疲劳、局部充血水肿、分泌物增多等。进入这个时期，人的喉部就开始前后、上下、左右迅速的发展。男xìng的甲状腺软骨会向前突出形成喉结，女xìng的上下伸展显露喉头的突出不明显，这是男女变声后的较大差别。
这是从网络上，查到的关于变声期的变化。为什么查这些？文晸佑表面上不说，心里还是在意的。智商164，学习成绩好。跆拳道红黑带2级，汉语英语超级流利。这些是很多人一辈子都未必能达到的水准。
但是除了钢琴十级，吉他熟练，唱歌乐感不错不跑调以外，文晸佑做为练习生，很多事基本都要重头学起。被李洙英收为学生后，第一项测试的就是自己的嗓音。虽然处于变声期，测试的不准确。然而文晸佑依旧留意李洙英那个评价，音调偏低。
变声期之前，文晸佑貌似记得自己音调其实很高。有一次和他哥开玩笑比谁的声音能把对方压过，自己还完胜了呢。虽然也有一些他哥让着他的嫌疑。所以他想好好查一下，变声期要持续多久，什么时候结束。需要注意的事项。
见李顺圭也认真看着，文晸佑皱眉：“你还没变声？女生比男生还早吧，尤其是你还比我大……”
文晸佑说到这，突然笑了：“这么一对比，你好像什么都比正常孩子晚。我看你是输定了。”李顺圭瞥了他一眼，没理他继续看着。
不一会摸摸下巴，摇头开口：“看来得注意保养了。要不嗓子变声后估计影响音质。”
文晸佑抿起嘴角，突然看着李顺圭：“怎么保养？上面说应注意胶原蛋白和弹xìng蛋白的摄入。具体指的是什么？”
李顺圭握住鼠标拖拽页面：“上面不都写着吗？变声期的青少年应多吃些富含胶原蛋白和弹xìng蛋白质的食物，如猪蹄、猪皮、蹄筋、鱼类、豆类、海产品等……得让哦妈给我准备。”
文晸佑不动声sè地附和着，不一会眯起笑眼：“顺圭啊，让咱妈多准备一份不好吗？也不是多麻烦多贵，捎带手的事。”
李顺圭惊讶地张大嘴，失笑推他一下：“摸呀？！还咱妈？我发现你这人怎么这么厚脸皮，为了达到目的真是什么都能说出口。”
文晸佑耸耸肩：“很正常啊。社长现在是我老师，那他的夫人就是我师母。”
李顺圭撇嘴：“前面还有一个师字好吧？想吃找你自己哦妈……额。”
李顺圭突然意识到什么，停住话头。文晸佑面容平静地看着显示器，也没再说话。
气氛一时有些沉默。李顺圭咬着嘴唇，犹豫着要说什么，不一会终于吸了口气：“对不起。”
文晸佑转头看着她：“等你半天了，这很难吗？”
李顺圭微微偏头：“谁……谁能想到你这么小气。”
文晸佑失笑：“我还小气？貌似我没什么表现吧。”
摆手打断李顺圭的话：“我那份到底准不准备？”
李顺圭气愤瞪着他：“家人就可以这样被你利用，只换来一些吃的？”
文晸佑表情怪异：“我没有拿他们换东西啊。”
李顺圭语气一滞，站起指着他：“那你还让我道歉？”
文晸佑耸耸肩：“也是你自己主动的吧？我没要求。”
“你……”李顺圭努力想着什么要找回场子。
文晸佑笑着开口：“坐下吧，问你正事。”
李顺圭顺着台阶下来了，白他一眼：“什么事？”
文晸佑微微皱眉，突然看着她：“听说男生变声期过后，音调会下降八度的，是不是这样？”
李顺圭看着显示器：“上面怎么写着的……哦。是吧？你不都查到了吗？”
