Violet is a 9 -year -old little girl.She recently1 got taught about volcanoesin school， and she would like tosee one of them up close. That day，when Violet was leaving school， she puther hand in her pocket2 to take out thehouse keys， but suddenly3 the keys fellout of her hand and fell into a hole！

No matter4 how much Violet triedto get her key out of the hole， shecouldn’t！ A strange5 sound could beheard from inside the hole. Violet gotscared and quickly ran away！ But thewhole night， she was thinking about thesound she heard from that hole.

The next day， Violet was goinghome from school with her friendHannah. The apple in Hannah’shands fell into the hole when theyarrived at the hole. Hannah bent6down to pick up the apple， but Violetshouted， “Not！ Do not get close tothat hole！ It is a volcano！ ”“Whatare you saying？ A volcano must be abig mountain！ But this is only a littlehole！ ”Hannah said in surprise.

Violet was afraid and said，“Well， maybe this is a child volcanoand has not grown up yet！ ”Hannahsaid， “Where do you know？”Violetreplied， “Because yesterday heswallowed7 my keys and when Iwanted to take them off， I heard astrange sound！ ”

Hannah， who couldn’t believe8Violet’s words， bent down to pickup her apple， but suddenly sheheard the strange sound thatViolet had said. They ran awayand thought about how to savethe city from this dangerous9volcano. How should they notlet that volcano grow big？

The next day in science class，Violet and Hanna decided to ask theirteacher some questions about volcanoes：How does a volcano form？ How todestroy10 a volcano？ How to take careof a volcano？ How to bury11 a volcanoin the middle of the street？ Theirteacher was surprised by thesequestions; she didn’t know the answerto many of them.

After school， Hanna and Violetwent back to their little volcano andnoticed that the hole was bigger thanthe day before！ Hannah and Violet，who were very scared， went home asfast as they could.

At dinner， Violet asked her bigbrother， “What will you do if you findout that a volcano is growing in thestreet？”Violet’s brother， who did notbelieve her words， said with a laugh，“Iwill blow it， so it goes out！ ”Violet，who was angry12， said， “I am notkidding13！ I do not know！ Maybe I’llcall the fire department14！ ”

The next day， Violet and Hannadecided to go to the city fire station. Nomatter how hard they tried， they could notmake the firefighters15 believe that avolcano had appeared16 on the street！ Butone of the firemen agreed17 to go with themandseethelittlevolcano.

When they got to the hole， they saw ithad become bigger， and water was runningout of it！ Hannah and Violet shouted“， Thevolcano has erupted18！ ”And then they hid19 behind the fireman！ But the firemansaid with a laugh， “Do not be scared！ Thisis not a volcano！ The water pipe20 isbroken！ But you did a great help to thecity with this good work！ I will work it outvery quickly now！ Don’t worry at all！ ”

Hannah and Violet looked at eachother. Violet said to Hanna， “I think youwere right！ Volcanoes are in the mountains，not holes in the middle of thestreet！ ”

維奧萊特是一個9 歲的小女孩。她最近在學(xué)校學(xué)了關(guān)于火山的知識，她想近距離觀察其中一座火山。那天，當(dāng)維奧萊特離開學(xué)校的時候，她把手放進口袋里拿出家里的鑰匙，但鑰匙突然從她手中掉了下來，落進了一個洞里。

不管維奧萊特怎么努力想把鑰匙從洞里拿出來都做不到，她還可以聽到洞里傳來一種奇怪的聲音。維奧萊特嚇壞了，趕緊跑開了。但是整個晚上，她都在想從那個洞里聽到的聲音。

第二天，維奧萊特和她的朋友漢娜一起從學(xué)校回家。當(dāng)她們到達那個洞口時，漢娜手中的蘋果掉進了洞里。她彎下腰去撿蘋果，但維奧萊特喊道：“別靠近那個洞！那是個火山！”“你在說什么？火山得是一座大山！但這只是一個小洞！”漢娜驚訝地說。

維奧萊特感到害怕，說：“嗯，也許這是一個幼年火山，還沒有長大！”漢娜說：“你從哪里知道的？”維奧萊特回答說：“因為昨天它吞下了我的鑰匙，當(dāng)我想把它們拿出來的時候，我聽到了一種奇怪的聲音?！?/p>

漢娜不相信維奧萊特的話，彎腰撿起她的蘋果，突然她聽到了維奧萊特說的那個奇怪的聲音。她們逃跑了，思考著如何把這座城市從這個危險的火山中拯救出來。她們怎么才能不讓那個火山長大呢？

第二天的科學(xué)課上，維奧萊特和漢娜決定問老師一些關(guān)于火山的問題：火山是如何形成的？如何摧毀一座火山？如何處理一座火山？如何掩埋一座街道中間的火山？她們的老師對這些問題感到驚訝；許多問題她都不知道答案。

放學(xué)后，漢娜和維奧萊特回到她們的小火山那兒，然后注意到這個洞比前一天更大了！漢娜和維奧萊特非常害怕，以最快的速度回家了。

吃飯的時候，維奧萊特問她哥哥：“如果你發(fā)現(xiàn)街上有座火山在變大，你會怎么做？”維奧萊特的哥哥不相信她的話，笑著說：“我會吹口氣，然后它就熄了！”生氣的維奧萊特說：“我不是在開玩笑！我不知道怎么辦！也許我應(yīng)該給消防部門打電話！”

第二天，維奧萊特和漢娜決定去市消防局。無論她們怎么努力都無法讓消防員們相信街上出現(xiàn)了火山。但有一個消防隊員同意和她們一起去看看那個“小火山”。

當(dāng)她們到達那個洞口時，發(fā)現(xiàn)洞口越來越大，水正從洞里流出來。漢娜和維奧萊特喊道：“火山爆發(fā)了！”然后她們就躲到消防員身后。消防員大笑著說：“不要害怕！這不是火山！是水管破了！但是你們做了一件好事，對這個城市有很大的幫助！現(xiàn)在我會很快解決它！一點都不用擔(dān)心！”

漢娜和維奧萊特面面相覷。維奧萊特對漢娜說：“我想你是對的！火山只會在大山里，不會是街中間的一個洞！”
