How many different animal sounds can you make?

你能發出多少種不同的動物聲音？

I like to quack like a duck. Quack, quack, quack, quack...

我喜歡像鴨子一樣嘎嘎叫，或者像牛一樣哞哞叫。

而Squeaks真的很擅長......。[Squeaks squeaks] 

Lots of animals make noises, and in the summer, I like to listen for one of my favorite animal sounds.

很多動物都會發出聲音，而在夏天，我喜歡聽我最喜歡的動物之一的聲音聲音。 

你能猜到它來自什麼動物嗎？[蟬鳴] 

This noise does sound loud, so I can see why you would think it comes from a big animal.

這種聲音聽起來確實很響，所以我明白為什麼你會認為它來自於一個大動物。

The animal that makes this noise is smaller than my hand.

發出這種聲音的動物比我的手還小。

Cicadas are a type of insect that live all over the world, and they're famous for the noises that they make when it's hot out.

蟬是一種生活在世界各地的昆蟲，它們因以下原因而聞名：1.當外面很熱的時候，他們會發出聲音。 

A lot of people only hear the cicadas, though, and never actually see them.

不過，很多人只聽到蟬的聲音，而從未真正看到它們。它們不是

They're not very big insects, and many cicadas use camouflage to blend in with the trees and plants.

非常大的昆蟲，許多蟬使用偽裝，與樹木和植物融為一體。

But you can recognize them by their big eyes and clear wings that lie across their back.

但你可以通過它們的大眼睛和橫臥在背上的清晰翅膀認出它們。

Cicadas may be small compared to humans, or even Squeaks, but they still make some of the loudest animal sounds in the world, and there's a very good reason why.

蟬與人類相比可能很小，甚至與Squeaks相比也是如此，但它們仍能製造一些世界上最響亮的動物聲音。 [Squeaks is impressed] 而且有一個非常好的理由！這也是為什麼。 

我們在樹上看到的那些蟬？它們實際上是很古老的昆蟲，但它們已經他們的一生幾乎都在地下度過。 

They're actually pretty old for insects, but they've spent almost all of their lives underground.

It takes a baby cicada either 13 or 17 years to grow up, and while they're growing, they stay underground, where it's safe from predators that might want to eat them.

蟬寶寶需要13年或17年才能長大，而在它們成長的過程中，它們留在地下，以免被可能想吃它們的捕食者吃掉。 

Then, when they're old enough and it gets warm outside, they finally crawl up out of the ground.

然後，當他們長大了，外面變暖了，他們就真的爬出來了。地的。 

Can you imagine seeing the world for the first time after years underground in the dark?

你能想象在黑暗的地下生活多年後第一次看到這個世界嗎？

The thing is, once they come up above the ground, cicadas don't live for very long, usually just a few weeks.

問題是，一旦它們出現在地面上，蟬就活不長了。- 通常只有幾個星期。他們真的想找到另一隻蟬來擁有更多的蟬 但他們必須儘快完成! 

They really want to find another cicada to have more cicada babies with, but they have to do it quickly.

So, the male, or boy cicadas, make a really loud noise so the female, or girl cicadas, will know they're there.

是以，雄蟬，或稱男蟬，會發出非常大的噪音，所以雌蟬，或稱女蟬會知道他們在那裡。 

But cicadas make noises a bit differently than other animals.

但是蟬發出的聲音與其他動物的聲音有點不同。

For example, if I wanted to make a loud noise, I could use my voice and shout⏤although, I won't, since we're only using our inside voices in the Fort.

例如，如果我想發出響亮的聲音，我可以用我的聲音喊叫--儘管我不會，因為我們只在堡壘裡使用我們的內部聲音。 

But cicadas can't make noises with their mouths like we do.

但是蟬不能像我們一樣用嘴發出聲音。

Instead, they use a special body part called a tymbal to make their sound.

相反，他們使用一個特殊的身體部位，稱為鼓槌，來發出他們的聲音。

Cicadas have two tymbals, one on each side of their body.

蟬有兩個鼓點，在其身體兩側各一個。

Each tymbal is made of a very thin material called a membrane.

每個鼓都是由一種叫做膜的非常薄的材料製成。

Along the tymbal, there are stripes of thicker membrane, creating what look like ribs down the cicada's side.

沿著鼓膜，有一些較厚的條紋，形成看起來像肋骨的東西。蟬的身邊。 

When the cicada wants to make noise, they pull the ribs of their tymbal close together very quickly, creating clicking sounds as each rib hits the one next to it.

當蟬想發出聲音時，它們會把鼓槌的肋骨拉近。非常快，當每根肋骨撞擊到旁邊的肋骨時，會產生咔嚓聲。 

It's a lot like how you can make sounds with a bendy straw.

這很像你可以用一根彎曲的吸管來發聲。

If you move it back and forth really quickly, it makes a noise.

當你把彎曲的部分快速地移到一起或分開時...它發出了噪音。 

Cicadas can pull apart the ribs on their tymbals and then click them together again so quickly that each clicking sound runs into the next, creating one big, loud sound.

蟬可以拉開輪胎上的肋骨，然後又迅速地把它們合在一起。每一個點擊的聲音都會進入下一個，形成一個大的、響亮的聲音。 

Can you hear each click in the cicada song, Squeaks?

你能聽到蟬鳴中的每一聲嗎，吱吱？[Squeaks聽著，然後搖搖頭] 。 

Neither can I! They're so fast that it becomes almost impossible to tell each click apart.

我也不能!它們是如此之快，以至於幾乎不可能將每一次點擊區分開來。

Not to mention almost painfully loud⏤some cicadas can be as loud as a motorcycle engine!

更不用說幾乎是痛苦的聲音了。有些蟬可以像摩托車發動機一樣響亮！這是很正常的。 

One of the loudest cicadas in the world is the Walker cicada, which lives in North America.

世界上最響亮的蟬之一是沃克的蟬，它生活在北美洲。美國。 

Walker cicadas can be as loud as a honking car horn, and that sound can hurt your ears after a while.

沃克的蟬可以像汽車喇叭一樣響亮，而且聲音會傷害你的耳朵一段時間後。 

But if there's a female cicada around, she'll definitely hear it!

但是，如果周圍有一隻雌性蟬，她肯定會聽到的！然後她就可以飛過去。然後她就可以飛過去以找到發出這種聲音的蟬。 

Then, she can fly over to find the cicada making that sound.

So, if you hear that loud buzzing sound in the trees this summer, now you'll know where it's coming from.

是以，如果你在今年夏天聽到樹上的巨大嗡嗡聲，現在你會知道在哪裡它是從哪裡來的。這意味著附近有一隻蟬! [Squeaks squeaks的警告] 

你也要發出響亮的聲音？[Squeaks發出響亮的吱吱聲]。 

Have you ever heard any cicadas in your neighborhood?

你在你的鄰居中聽到過任何蟬嗎？

What's the loudest sound you've ever heard?

你所聽到的最響亮的聲音是什麼？
