" Is your air on?" asks Josh

“你空气瓶开了吗？”乔希问道。

" Is your air on?" asks Anne." Okay, let's go!"

“你空气瓶开了吗？”安妮问道。“好了，我们出发吧！”

Today Josh and Anne are taking us on a scuba-diving adventure near the Similan Islands in Thailand

今天，乔希和安妮要带我们在泰国斯米兰群岛附近进行一次水肺潜水冒险。

旁白 neutral

The water here is so clear that we can see things thirty meters away, and that's pretty far for being underwater!

这里的水非常清澈，我们能看到三十米外的东西，在水下这算是相当远的了！

旁白 neutral

Whenever people go scuba diving, they swim in a group for safety, so we had better stay together!

人们水肺潜水时，通常会结队同游以确保安全，所以我们最好待在一起！

旁白 neutral

There are hundreds of great places to scuba dive in the world, and each of them is different

世界上有数百个绝佳的水肺潜水地点，而且每个地方都各不相同。

旁白 neutral

Some places are very cold, or are filled with seaweed, or have only very small animals

有些地方非常寒冷，或者长满了海藻，又或者只有非常小的动物。

旁白 neutral

The Similan Islands, however, are great because the water is 28 degrees Celsius and crystal clear, and there are lots of big fish

不过，斯米兰群岛很棒，因为这里的水温有28摄氏度，而且清澈见底，还有许多大鱼。

旁白 neutral

In fact, look over there! Josh has found a moray eel hiding in the rocks

其实，看那边！乔希发现了一条躲在岩石里的海鳝。

旁白 neutral

Don't worry; it is more frightened of us than we are of it

别担心，它怕我们，胜过我们怕它。

旁白 neutral

Look at its sharp teeth!

看它锋利的牙齿！

旁白 neutral

It has two sets of jaws to pull its prey in, so keep your hands far away!

它有两副颌骨来吞食猎物，所以把手放远点！

旁白 neutral

Eels aren't very friendly creatures, as you can tell, and they mostly live alone

你看得出来，鳗鱼不是非常友好的生物，它们大多独居。

旁白 neutral

So we probably won't see another eel for quite a while

所以我们很可能好一阵子都看不到另一条鳗鱼了。

旁白 neutral

Did you know that there are hundreds of plants that live underwater?

你知道吗，水下生活着数百种植物？

旁白 neutral

Thailand has many kinds

泰国有许多种类。

旁白 neutral

One plantlike creature is called coral, and there are two kinds: hard coral and soft coral

有一种像植物的生物叫珊瑚，分为两种：硬珊瑚和软珊瑚。

旁白 neutral

A coral is built from live cells that stack on top of each other in layers

珊瑚是由活的细胞一层层地堆叠而成的。

旁白 neutral

When the outer layer gets old, a new layer of cells forms around it so the plant grows taller or wider

当外层变老时，周围会形成一层新的细胞，这样植物就能长得更高或更宽。

旁白 neutral

Like their names suggest, hard coral is stiff, while soft coral is able to sway with the ocean current

顾名思义，硬珊瑚质地坚硬，而软珊瑚能够随洋流摇曳。

旁白 neutral

Both soft and hard coral grow very slowly

软珊瑚和硬珊瑚都长得非常缓慢。

旁白 neutral

Look, this fan coral grows about one centimeter each year, so Anne is careful not to touch it as she swims by

看，这棵扇形珊瑚每年大概只长一厘米，所以安妮游过时很小心不去碰到它。

旁白 neutral

Touching a coral can kill it, and sometimes it can hurt us too so we stay far away

触碰珊瑚可能会让它死掉，有时也会伤到我们，所以我们离得远远的。

旁白 neutral

Look, down at the bottom — there's a whale shark, the biggest fish in the world!

看，在底下——有一条鲸鲨，世界上最大的鱼！

旁白 neutral

Anne is trying to get her picture taken with it, but don't worry, this shark won't bite

安妮正试着和它合影，不过别担心，这条鲨鱼不会咬人。

旁白 neutral

Whale sharks only eat small animals and tiny plants that float in the water called plankton

鲸鲨只吃水里漂浮的小动物和微小植物，这些叫浮游生物。

旁白 neutral

Still, we're careful not to disturb the shark since this is its home

不过，我们还是很小心地不去打扰它，因为这里是它的家。

旁白 neutral

Josh is checking his pressure gauges, and signals to Anne that he is almost out of air

乔希正在查看他的气压表，然后向安妮示意他快没气了。

旁白 neutral

Men use up air faster than women because their lungs are bigger and because they have more muscle

男性用气比女性快，因为他们的肺更大，肌肉也更多，

旁白 neutral

but I think we have enough time to look at just a couple more creatures

但我觉得我们还来得及再看上一两种生物。

旁白 neutral

Oh no, Anne is giving the danger signal! She found a sea snake

哦糟了，安妮发出了危险信号！她发现了一条海蛇。

旁白 neutral

This underwater creature may be tiny, but its venom is twenty times more poisonous than any snake on land!

这种水下生物虽然可能很小，但它的毒液比陆地上任何一种蛇都要毒上二十倍！

旁白 neutral

It eats mostly small fish by paralyzing them first with one quick bite

它主要吃小鱼，先用飞快的一口把鱼麻倒。

旁白 neutral

It takes less than a second for its venom to work

它的毒液起作用还不到一秒钟。

旁白 neutral

The sea snake seems to be a little hungry, so we'll move on

这条海蛇好像有点饿了，我们继续往前走吧。

旁白 neutral

Here is Josh's favorite animal, the cuttlefish

这是乔希最喜欢的动物，墨鱼。

旁白 neutral

Many people eat cuttlefish thinking it is an ordinary squid, but it is really an amazing animal

很多人吃墨鱼，以为它就是普通的鱿鱼，但它其实是一种很神奇的动物。

旁白 neutral

Watch carefully. The mother cuttlefish is trying to protect its baby by distracting us

仔细看。这只墨鱼妈妈想引开我们的注意，好保护自己的宝宝。

旁白 neutral

See how its skin is changing colors so that we can see it better?

看到它的皮肤在变色了吗？这样我们才能把它看得更清楚。

旁白 neutral

Cuttlefish can change the color and texture of their skin to match anything around them

墨鱼能改变自己皮肤的颜色和质地，变得和周围的任何东西一样。

旁白 neutral

For example, if there is a field of black rocks nearby, their skin will turn bumpy and black

比如说，如果附近有一片黑乎乎的石头，它们的皮肤就会变成凹凸不平的黑色。

旁白 neutral

If they swim by green seaweed, they will turn smooth and green

要是它们游过绿色的海草，就会变成光滑的绿色。

旁白 neutral

If you put down a purple polka-dot blanket, their skin will have polka dots!

假如你铺下一张紫色圆点图案的毯子，它们的皮肤上就会出现圆点！

旁白 neutral

It looks like Josh is low on air

看来乔希的空气不够了。

旁白 neutral

It's time to return to our own world above-water, but don't be disappointed

是时候回到我们水上的世界了，不过别失望。

旁白 neutral

There will always be another adventure!

总会再有下一次冒险的！
