Last summer, my at a loose end does not have a thing, outside looking at a window green the tree that must shine, listening to “ cicada, of cicada ” one in succession euphonic and pleasant cicada cries, curiosity is driving me, why can cicada keep singing? I go asking father, father is laughing to say “ when I see cicada is crying only, abdomen rouses, and cicada's wings is in as the rhythm of abdomen fan, as to why can sing, I am not clear also. ” is taking this mystery that indissoluble, my think hard is worn.
去年暑假，我闲着没事，望着窗外一棵棵绿得发亮的树木，听着“知了，知了”的一声声悦耳动听的蝉鸣，好奇心驱使着我，蝉为什么会不停地唱歌呢？我去问爸爸，爸爸笑着说“我只看见蝉在叫的时候，肚子一鼓一鼓的，而且蝉翼随着肚子的节奏在扇动，至于为什么会唱歌，我也不明白。”带着这个不解之谜，我冥思苦想着。
What does cicada rely on to sound? To reveal this secret, I often hide in the stealthily observation below the tree. When discovering cicada bleats in observation, always like “ to look up ” , “ holds out ” of pectoral ” , “ wing end. Is this why?
蝉靠什么发出声音呢？为了揭开这个秘密，我常常躲在树下悄悄地观察。在观察中发现蝉鸣叫时，总是喜欢“抬头”、“挺胸”、“翅尾”。这又是为什么呢？
Honest An Nai does not live my curiosity, one day, I thought a way caught a cicada, had careful observation and research. I first pick off the big wing of cicada, put it to the ground, it is worn in the desperately beat on the ground, crying ringingly, look it is not the sound that gives out from big wing. I broke off again the mouth of cicada, but it still exerts all its strength the ground is crying, I think also do not sound from its mouth. Is cicada what to pronouncing rely on after all? Observe through relapsing, I discover this sound is like come out from bosom hair. Then, I discover it is sunken the two side of the ministry have a scale each like incrustation, like Qian Jia, there are a pair of transparent films inside. When cicada cries, frivolous case vibrates back and forth, I hold this place gently with handle gently, cicada cried, I keep holding, cicada keeps giving out that deafening cry, my composition thinks: This film should be its acoustic generator! I defeat filmy thorn, held again next, it also did not cry again. Really strange!
实在安奈不住我的好奇心，一天，我想了个法儿捉到了一只蝉，进行了仔细观察和研究。我先摘掉了蝉的大翅膀，把它放到地上，它在地上拼命地扑打着，清脆地叫着，看来它并不是从大翅膀里发出的声音。我又折断了蝉的嘴，可它仍然使劲地叫着，我想也不是从它嘴里发出声音的。蝉究竟是靠什么发音的呢？经过反复观察，我发现这声音好像是从胸部发出来的。于是，我发现它凹部的两侧各有一片鱼鳞似的硬壳，像钳甲一样，里面有一对透明薄膜。蝉鸣时，薄壳来回地颤动，我用手轻轻一捏这个地方，蝉就叫了，我不停地捏，蝉就不停地发出那震耳欲聋地叫声，我作文想：这片薄膜应该就是它的发声器吧！我把薄膜刺破，然后再捏了一下，它再也不叫了。真奇怪！
Later, I consulted data. In the abdomen of male cicada two side are giving birth to ” of two “ musical instrument each, upper part of abdominal alveolus acupuncture point has thin thin cover, have inside like tympanic pronunciation film, this is the “ castanet ” with male peculiar cicada, also be the acoustic generator of male cicada, systole of muscle of pronunciation film interior is oscillatory, cicada can sound. Cicada does not have Hou ministry, also do not have vocal cords, be impossible to sing. It can sound the ” of “ musical instrument that relies on abdomen completely. Female cicada does not have “ castanet ” , won't sound, so people calls it cicada of “ dummy ” .
后来，我查阅了资料。在雄蝉的腹部两侧各生着两付天然的“乐器”，腹部的小孔穴上方有一块薄薄的盖片，里面有像鼓皮似的发音膜，这是雄蝉特有的“响板”，也是雄蝉的发声器，发音膜内部肌肉收缩振动，蝉就会发出声音。蝉没有侯部，也没有声带，是不可能唱歌的。它之所以能发出声音全靠腹部的“乐器”。雌蝉没有“响板”，就不会发出声音，所以人们叫它“哑巴”蝉。
At this moment, I just understand, when cicada cries, why to often love “ to look up ” , “ holds out pectoral ” , “ to become warped end ” . Original, cicada gentleman won't “ sings ” , it just is performing ” of “ musical instrument just ah!
这时，我才明白，蝉叫的时候，为什么老爱“抬头”、“挺胸”、“翘尾”了。原来，蝉先生不会“唱歌”，它只是在演奏“乐器”而已啊！
I picked a floret in scientific garden, a small fish was caught in intellectual ocean. Ah, there is science everywhere in the life, want you to have a pair of eyes of discovery only, can find it.
我在科学的园地里摘到了一朵小花，在知识的海洋里捕到了一条小小鱼。啊，生活中到处都有科学，只要你有一双发现的眼睛，就能找到它。
The contain in the thing beside us is worn lots and lots of science, awaiting us to discover. Why can the young writer of the article sing to can solve cicada and catch designedly come a male cicada undertakes observing carefully study, consult data, the result discovers cicada euphonic interjectional origin ” of its abdominal “ musical instrument. Picture is meticulous and true, the language is fluent, dramatic image. Young writer seeks knowledge exploration, attentive observation is really commendable.
我们身边的事物中蕴涵着许许多多的科学，等待着我们去发现。本文的小作者为了能解到蝉为什么会唱歌而特意捉来一只雄蝉进行仔细观察研究，查阅资料，结果发现蝉悦耳地叫声来源它的腹部“乐器”。描写细致真实，语言流畅，生动形象。小作者求知探索，细心观察确实可贵。(文/余佳金)
