题目内容
14．Honk!Squeak!What is that？If you're going through puberty（青春期），it could be your voice．Both boys and girls experience voice changes as they grow older，but girls'voices get only a little deeper．A boy's voice，on the other hand，may change quite a bit-from sounding like a little kid to sounding like somebody's dad!
How does this happen？The larynx，your voice box，actually gets bigger during puberty．One of its jobs is to let you talk，sing，hum，yell，laugh，and make all sorts of noises．
When a boy reaches puberty，his body begins making lots of testosterone（睾丸激素），which causes his larynx to grow and his vocal cords（声带） to get longer and thicker．
Before puberty，your larynx is pretty small and your vocal cords are kind of small and thin．That's why your voice is higher than an adult's．As you go through puberty，the larynx changes．As your body adjusts to this changing equipment，your voice may"crack"or"break"．But this process lasts only a few months．
Not only do older guys and men sound different from boys，but you can also see the difference in their necks．When the larynx grows bigger，part of it sticks out inside the neck．You can see it at the front of the throat．This is known as the Adam's apple．For girls，the larynx also grows bigger but not as much as in boys，so you can't see it through a girl's skin．
Everyone's timetable is different，so some kids'voices might start to change earlier and some might start a little later．Some voices might drop gradually，while others might drop quickly．
If this hasn't happened to you yet，don't worry．And if you're going through this now，try not to stress too much about the funny noises you make．It can help to talk to a parent，or a friend who's already gone through the voice change．Before you know it，your voice will sound clear，strong，and more grown-up!

分析 本文为科教类说明文，文章介绍了青春期男孩和女孩声音的不同变化，分析变化的原因以及如何变化；并且分析男孩在声音变化的同时喉结的产生，青春期女孩没有发育长出喉结的原因；最后作者安慰孩子们，这是生理的自然现象，不必担心，这段时期很快就会过去．
解答 60．答案为C．主旨大意题；本文旨在说明青春期男孩和女孩声音为什么发生变化以及如何变化的；他们应该如何对待这个现象；故选C．
61．答案是B．推断题；由第四段的最后一句"which causes his larynx to grow and his vocal cords（声带） to get longer and thicker这使得他的喉生长，声带长长、变厚"和第五段的前两句"Before puberty，your larynx is pretty small and your vocal cords are kind of small and thin．That's why your voice is higher than an adult's．青春期前，你的喉咙小，声带小而细，那就是你的声音比成年人高的原因"推断，成年人声音低是因为声带长而厚，故选B．
62．答案是C．细节理解题；由第六段中"Not only do older guys and men sound different from boys，but you can also see the difference in their necks．不仅仅年龄大点的小伙子和男人的声音与男孩不同，你还能看到他们的脖子也不同"，下文分析了具体的不同，即the Adam's apple（喉结），由此判断答案是C．
63．答案是A．推理判断题；由最后两段分析可知，每个人都会出现这种现象，时间早晚不同，无论是早或晚，不要担心，这段时期很快过去；可见作者认为这是生理的自然变化，无需担心，故选A．
