ABC，听着。
ABC listen.
你好。
Hello.
我叫Nij。
My name is Nij.
今天在《想象一下》这个节目里，我在帮人带孩子。
And today on Imagine This, I'm babysitting.
哎呀，真可爱的小宝宝。
Aw, cute baby.
她挺吵的。
She's loud.
是啊。
Yeah.
乖，别怕，小宝贝。
You're okay, little one.
咱们哄她睡觉吧。
We can put her to sleep.
再给她喂点奶。
Can give her some more milk.
说不定她该洗个澡了。
Maybe she needs to have a bath.
你累不累啊？
But you okay?
要不唱首歌？
Sing a song?
我来唱《小星星》吧。
I would sing my twinkle twinkle little star.
哎，我真好奇你是个什么样的小家伙。
Oh, I wonder what you are.
嘿。
Hey.
嘿。
Hey.
有效果了。
That's working.
挺好。
Good.
宝宝真可爱。
Babes are cute.
是啊。
Yeah.
她太招人喜欢了。
She's adorable.
但他们还能让她这样吗？
But could they still let her?
咕咕咕咕。
Goo goo goo goo.
想想看，我们所有人当初都是从同一个起点开始的，真不可思议。
It's amazing to think we all started out the same way.
我爸爸小时候也是个婴儿？
Even my dad was a baby?
对啊。
Yeah.
但在我们变成现在这么可爱、流口水、咕咕叫的阶段之前，到底发生了什么？
But what happens before we get to this cute, drooly, gurgling stage of life?
这其实正是很多人的疑问。
That's what a lot of you have been wondering.
嗨。
Hi.
我叫莉齐，今年七岁。
My name is Lizzie, and I'm seven years old.
我叫麦肯齐，今年九岁。
My name is Mackenzie, and I'm nine years old.
嗨。
Hi.
我叫露丝，今年七岁。
My name is Ruth, and I'm seven years old.
我是阿奇，十一岁。
I'm Archie, and I'm 11 years old.
我是麦克，八岁。
I'm Mack, and I'm eight years old.
嗨，想象一下。
Hi, Imagine This.
我叫鲁本，八岁。
My name's Reuben, and I'm eight years old.
嘿。
Hey.
我叫卢安娜。
I'm Luana.
我四岁了。
I'm four years old.
嗨。
Hi.
我叫格雷森，五岁。
My name's Grayson and I'm five years old.
我想知道宝宝是怎么来的。
I would like to know how babies are made.
宝宝到底是怎么来的？
How are babies really made?
我想知道宝宝是怎么在妈妈肚子里长大的？
I wanna know how do babies grow on mommy's tummies?
咱们去问问图乌赫瓦卡·凯图乌·林诺教授吧。
We should talk to Professor Tu'uhevaha Kaitu'u Lino.
她是墨尔本大学妇产科的副主任。
She's the deputy head of the Department of Obstetrics and Gynecology at the University of Melbourne.
产科学就是研究怀孕和分娩的。
Obstetrics is the study of pregnancy and childbirth.
我觉得图乌赫瓦哈能帮我们解答所有这些问题。
I think Tu'uhevaha will be able to help us with all these questions.
不过我得先把这个小家伙送回去。
But let me go drop off this little one first.
嘿，尼吉。
Hey, Nij.
教授好。
Hi, professor.
大家好。
Hi, everyone.
嗨。
Hi.
你好。
Hello.
见到你真好。
Nice to see you.
你在这儿医院工作吗？
Do you work at the hospital?
对，我在这儿医院当科学家，帮准爸妈们顺利生下健康的小宝宝。
I do work here at the hospital as a scientist, helping families with their pregnancies to deliver healthy babies.
宝宝都是在这儿出生的吗？
Is this where babies come from?
在医院里？
In a hospital?
他们来这儿之前，在哪儿呢？
Where were they before they get here?
在我们出生之前，可发生了很多事，通常得花九个月左右。
A lot happens before the day we are born, and it usually takes about nine months.
是从妈妈肚子里出来的吗？
From someone's belly?
大肚子啊。
A big belly.
对。
Yep.
孕妇的肚子确实会变得很大，但宝宝可不是长在胃里。
A pregnant belly can get really big, but the baby isn't growing inside the stomach.
宝宝是在一个叫子宫的地方长大的。
It all happens in a body part called the uterus.
子宫。
Uterus.
听着像颗星球。
Sounds like a planet.
不是。
No.
那是你的阴茎。
That's your penis.
从外面很难看清楚里面到底发生了什么。
It can be hard to see what's happening from the outside.
咱们得发挥想象力，才能明白这一切是怎么运作的。
We'll have to use our imaginations to see how it all works.
对。
Yeah.
走吧。
Let's go.
好黑啊。
It's so dark.
啥也看不见。
I can't see anything.
哦，是宝宝吗？
Oh, is it, baby?
一开始可不是。
Not at first.
这一切始于两个特别的细胞——一个卵细胞和一个精子细胞，分别来自两个人。
It all starts with two very special cells, an egg cell and a sperm cell that come from two different people.
那是什么？
What is that?
是宝宝的心跳吗？
Is that the baby's heartbeat?
我们听到的是大人的心脏。
That's the grown up's heart we can hear.
嘿，快看。
Hey, look.
前面那是什么？
What's that up ahead?
看起来像只蝌蚪。
It looks like a tadpole.
它在变化呢。
It's morphing.
这是精子细胞。
That's a sperm cell.
它特别特别小，但特别重要。
It's really, really small, but it's very important.
里面带着DNA。
It carries DNA inside it.
我们以前学过DNA。
We've learned about DNA before.
就是决定身体怎么长的那东西。
It's the stuff that says how our bodies should be put together.
每个人都有自己的DNA。
Everyone has their own DNA.
它就在你身体里。
It's in your body.
是从你爸妈那儿来的。
It comes from your mom and dad.
是的
Yep.
我们体内的DNA，有一半就来自这一个小小的精子。
Half of our DNA comes from just one of these little sperm cells.
它要进入一个大球里。
It's going inside a big ball.
那是什么？
What's that?
那是卵细胞。
That's an egg cell.
鸡蛋？
An egg?
像鸡下的蛋那样？
Like a chicken.
人也是从卵细胞来的。
Humans come from eggs too.
它们就在身体里面，外面没有硬壳。
They're just inside the body, and they don't have a hard shell.
宝宝是从蛋里破壳出来的，他们还跟我说，我准备孵化了。
Babies crack out of eggs, and they tell me, I'm ready to hatch.
不是的。
No.
根本不是。
No.
从一个蛋开始，然后慢慢长大，越来越大，再继续长。
Start from an egg, and then they, like, grow bigger and bigger and bigger and then bigger.
对。
Yep.
我们现在看得很清楚，但现实中，卵细胞小得跟沙粒似的。
We're seeing this up close, but in real life, an egg cell is a tiny speck, smaller than a grain of sand.
而精子还要再小一万倍。
And a sperm cell is 10,000 times smaller than that.
这一切都太小了。
It's all so tiny.
可我们后来却长得这么大。
And we grow up to be so big.
卵细胞提供了我们另一半的DNA。
The egg cell is where the other half of our DNA comes from.
哇哦。
Woah.
精子细胞没了。
The sperm cell's gone.
它已经完全融入卵细胞里了。
It's disappeared inside the egg cell.
等等。
Wait.
继续。
Go.
一切就是从这儿开始的。
This is how it all starts.
这叫受精。
It's called fertilization.
这两种特殊的细胞结合在一起，形成了一个新的细胞——受精卵。
These special cells join together to create this one new cell, a fertilized egg cell.
我现在身体里有多少个细胞啊？
How many cells am I made of now?
五万两千个。
Five Twenty thousand.
远不止这些。
Way more.
我们身体里有数万亿甚至更多的细胞，全都紧紧黏在一起，拼命工作来构建我们的身体。
We're made of trillions and trillions of cells, all stuck together and working hard to make our bodies.
真不敢相信，我们所有人居然都来自一个细胞。
I can't believe we all just come from one cell.
但咱们可不会一直保持那样。
But we don't stay that way for long.
你瞧。
Look.
卵子在动呢。
The egg is moving.
它刚裂开了？
Did it just break?
对。
Yes.
它分裂成了两个一模一样的。
It split and made two of itself.
它又来一次了。
It did it again.
现在变成四个了。
Now there's four of them.
不。
No.
不。
No.
不。
No.
等等。
Wait.
别动。
Hang
等等。
on.
8。
8.
9107。
9107.
哇哦。
Woah.
哇哦。
Woah.
16。
16.
32。
32.
太多了，数不过来。
So much to count.
我快跟不上了。
I can't keep up.
对。
Yep.
几乎一眨眼的功夫，卵细胞就开始不断分裂，一个变两个，两个变四个。
Almost immediately, the egg cell starts to make lots of copies of itself by splitting into two.
然后这两個又各自分裂成兩個，就这样一直持续大约五天。
Then those two make another two and on and on for about five days.
因为宝宝会哭啊。
Because the babies cry.
对。
Right.
对。
Right.
对。
Right.
对。
Right.
大概一周后，这一小团细胞就会往下移动到子宫里，找个舒服的地方安顿下来，一直待到生孩子。
About a week, this tiny collection of cells moves down lower into the uterus and finds a comfy place to stay for the rest of the pregnancy.
哇。
Woah.
我们开始了
We're on
在移动呢。
the move.
现在算宝宝了吗？
Is it a baby yet?
还没呢。
Nope.
已经从一个细胞长到大概三百个了，但还是比一粒米还小。
It's grown from that one cell to about 300 cells, but it's still smaller than a grain of rice.
好小啊，跟碎屑似的。
That's so small, like crumsy.
现在还没成型，连器官都还没有呢。
It doesn't have any shape yet, and there are no body parts.
喂。
Hey.
它在慢慢消失了。
It's disappearing.
我再也看不见它了。
I can't see it anymore.
它去哪儿了？
Where's it going?
它正往子宫壁里钻，好跟妈妈的身体连上。
It's burying itself into the side of the uterus so that it can connect the mother's body.
从这儿开始，我们就再也看不到它了。
We won't be able to see it anymore from here.
那咱们跟着它看看。
So let's follow it.
接下来八周，这些细胞会一直分裂、越来越多。
For the next eight weeks, the cells will keep growing and making more of themselves.
现在还称不上是宝宝呢。
It's not a baby yet.
这是个胚胎。
It's an embryo.
现在发生什么了？
What's happening?
是不是像胚胎在长根一样？
It's like the embryo is growing roots?
是的。
Yes.
差不多就是这么回事。
It's a bit like that.
怀孕的头两个月，全都在建立妈妈和胚胎之间的连接。
These first two months of a pregnancy are all about setting up a connection between the mother and the growing embryo.
胚胎。
Embryo.
什么样的连接？
What kind of connection?
这叫胎盘。
It's called a placenta.
它长得有点像跟宝宝一起长出来的枕头。
It looks a bit like a pillow that grows alongside the baby.
这是怀孕期间身体长出来的一个全新器官。
It's a whole new organ the body grows during pregnancy.
哇哦。
Wow.
胎盘是干什么用的？
What does a placenta center do?
它把妈妈体内的氧气和营养传给胚胎，让它能继续发育。
It moves oxygen and nutrients from the mother's body to the embryo so that it can keep growing.
因为胚胎长得可快了。
Because it's growing a lot.
你瞧。
Look.
胚胎里的所有细胞都在不停地移动。
All the cells are moving around inside the embryo.
对。
Yes.
胚胎的细胞会自己组织起来，形成将来会长出不同器官的区域。
The cells of the embryo organize themselves into the areas where different body parts will grow.
脊髓和大脑的细胞聚在一起，马上开始工作。
Spine and brain cells huddle together and get to work.
来形成大脑。
To make a brain.
对。
Yes.
肺部的细胞则开始搭建呼吸用的管道。
And lung cells start to create tubes for breathing.
肺部发育得慢，所以这些细胞得特别早就开始干活。
Lungs take a long time to grow, so those cells have to get started really early.
那所有细胞是怎么知道自己该变成什么的呢？
How do all the cells know what to become?
就像是它们在互相交流一样。
It's kind of like they talk to each other.
怎么交流？
How?
通过读取DNA，然后互相传递大量信号。
By reading the DNA and sending lots of messages to each other.
这个胚胎阶段大概持续十周。
This embryo stage lasts about ten weeks.
这时候主要是在搭建身体的框架，就像画画之前先勾个轮廓。
It's all about setting up the structure of the body, kinda like drawing an outline before you color in the picture.
这哪像婴儿的轮廓啊。
That doesn't look like an outline of a baby.
它还有条尾巴呢。
It's got a tail.
你确定我们是在人身体里吗？
Are you sure we're in a human body?
当然了。
Yes.
人类胚胎是有尾巴的。
A human embryo has a tail.
你怎么知道的？
How'd you know that?
说不定是我弄丢的。
Maybe I dropped it.
它确实没了。
It did go away.
但你尾巴还留了一小截呢。
But a little bit of your tail is still there.
我们现在可没有尾巴了。
We don't have tails now.
不是。
No.
但你确实有个尾骨。
But you do have a tailbone.
哇哦。
Woah.
现在这个胚胎看起来更像个小婴儿了。
The embryo looks more like a small baby now.
十周之后，我们就叫它胎儿了。
After ten weeks, we start calling it a fetus.
越来越多的细胞长出来，形成了头、身体、胳膊和腿。
More and more cells have grown and created a head, body, arms and legs.
但它还不能算个婴儿。
But it's not a baby yet.
现在只有草莓那么大。
It's only the size of a strawberry.
哇哦。
Woah.
那是什么？
What's that?
那是心跳声。
That's the heartbeat.
嗨，小胎儿。
Hi, little fetus.
你好。
Hello.
嗨。
Hi.
克勒图斯，小胎儿。
Cletus the fetus.
嗨，尼克。
Hi, Nick.
你长得真好。
You're growing so well.
你真结实。
You're so strong.
继续加油啊。
Keep up the hard work.
现在他还听不见你说话。
It can't hear you yet.
耳朵还在长呢。
The ears are still growing.
这里面怎么这么多液体？
What's all this liquid in here?
就像泡个温水澡一样。
It's like a warm bath.
现阶段嘛， mostly 就是水。
For now, it's mostly water.
这能保护胎儿，不让它被撞到或戳到。
It helps keep the fetus safe so it doesn't get bumped or poked too much.
还能保持温暖。
And it keeps things nice and warm.
躺在背上漂着，真舒服放松。
Nice and relaxing, floating on my back.
那胎儿在水里怎么呼吸啊？
But how can the fetus breathe underwater?
它不呼吸。
It doesn't.
胎儿的氧气和所有营养都是通过脐带从胎盘获取的。
The fetus gets its oxygen and everything it needs from the placenta through the umbilical cord.
一根连着妈妈身体的脐带，营养顺着下来，直接通到宝宝的肚子上。
A cord that connects down to mom's body, and then the food runs down, and it connects to the baby's belly.
没错。
Exactly.
就在这儿。
There it is.
像一根管子，一头连着肚脐，另一头连着胎盘。
It's like a tube that goes into the belly button, and the other end of the tube connects to the placenta.
一头连着宝宝，另一头连着妈妈。
So one's connected to the baby and one's connected to the mommy.
对。
Yep.
胎儿不需要的废物，也通过这根管子排出去。
Any waste or things the fetus doesn't need gets sent back out that way too.
胎盘在妈妈的身体和胎儿之间来回交换物质。
The placenta swaps things back and forth between the grown up's body and the developing fetus.
水桶、针头、番茄酱。
Bucket, needles, tomato sauce.
但无聊的是，他们根本尝不到味道。
But the boring thing is that they don't get to taste it.
我听到音乐了。
I can hear music.
听着像在开派对。
Sounds like a party.
嘘。
Shh.
宝宝在睡觉。
The baby's sleeping.
你看到了吗？
Did you see that?
宝宝在动。
The baby's moving.
看到了。
Yes.
大概四到五个月后，胎儿就能听到声音，甚至能认出熟悉的声音。
After about four or five months, the fetus can hear sounds, even recognise familiar voices.
现在真的看起来像个宝宝了。
Definitely looks like a baby now.
宝宝小小的，正安静地躺着睡觉呢。
The baby is little, and it's sitting there asleep.
它偶尔还会踢妈妈的肚子，不过还裹在羊水囊里呢。
And it sometimes pokes mama's belly, and it's in the sack.
我现在能出来了吗？
Can I come out now?
还不能呢。
Not yet.
现在也就芒果那么大。
It's still only the size of a mango.
虽然看着像个小人儿了，但肺还没发育好，没法自己呼吸，大脑和其他器官也还在长呢。
Even though it now looks like a baby, its lungs aren't strong enough to breathe on their own, and the brain and the other organs are still growing.
哇哦。
Woah.
它在动。
It's moving.
是特里。
It's Terry.
我太累了。
I'm so down.
这儿越来越挤了。
It's getting a bit crowded in here.
感觉一点空间都没有了。
It feels like there's no space at all.
经过九个月的发育，从一个细胞长成数万亿个细胞，构成了皮肤、肌肉、器官和骨骼，现在是时候来到这个世界了。
After about nine months of growing, from that one single cell to the trillions that shape the skin, muscles, organs and bones, it's time to get out into the world.
哇哦。
Woah.
身体好像在催我们该出去了。
It feels like the body is telling us to leave.
差不多就是这么回事。
It is a bit like that.
身体给子宫发了好多信号，叫它准备迎接
Lots of messages are being sent to the uterus to get ready for
分娩。
birth.
分娩？
Birth?
哎呀，木头走了。
Oh, the wood is leaving.
尼吉，你把虫子从虫子里弄出来没？
Nij, did you take the bug out of the bug?
没有。
No.
不是我干的。
It wasn't me.
子宫里流出的所有液体，叫破水。
All the liquid leaving the uterus is called the water breaking.
东西破了？
Something's broken?
别担心。
Don't worry.
这本来就是正常的。
That's supposed to happen.
快了，就在这时候。
It's almost time.
接下来该我们退场了，让胎儿自己完成这段旅程。
And it's our cue to leave and let the fetus do this next part of the journey on its own.
呼——
Phew.
真是够刺激的。
What a wild ride.
接下来会发生什么？
What happens next?
妈妈们得使出浑身力气推孩子出来。
The mummies have to try and push the baby out so hard.
妈妈跟我说，他们用吸盘把孩子吸出来的，那会儿他脑袋红得厉害。
Mama told me they had to push him out with the suction cup, and he had a very red head.
对。
Yep.
有些宝宝是靠子宫收缩、从阴道生出来的。
Some babies are born when they are pushed from the uterus and out through the vagina.
还有些是通过剖腹产手术，医生帮忙安全接生的。
Others are born with a special operation called a cesarean section, where doctors help them to get out safely.
有些宝宝早产了，得在医院住一阵子，等身体更强壮了才能回家。
Some babies arrive a little early and might need to stay in hospital while they grow stronger before they can go home.
也有宝宝是在家出生的，有的在床上，有的甚至在浴缸里。
Some babies are born at home, some in bed and some in the bath.
来到这个世界的方式可多了。
There are lots of ways to enter the world.
哇哦。
Wow.
欢迎你，小宝贝。
Welcome, little one.
我没听见。
I didn't hear it.
没有。
No.
这完全正常。
That's totally normal.
宝宝身上通常会有点血，因为胎盘刚从子宫壁上剥离下来。
There is usually some blood on the baby from the placenta because it had to detach from the uterus.
可是宝宝不是需要胎盘吗？
But doesn't the baby need the placenta?
现在不用了。
Not anymore.
如果宝宝在子宫里完整待了九个月，他们的肺就已经足够强壮，可以自己呼吸了。
If babies have spent their full growing time, around nine months, inside the uterus, their lungs are now strong enough to breathe on their own.
特别。
Very
强壮的肺。
strong lungs.
我们每个人经历的这段旅程，真是不可思议。
What an incredible journey we all go on.
当然啦，每个人的旅程并不完全一样。
It's not exactly the same journey for everyone, of course.
我们每个人都不太一样。
We're all a little bit different.
我特别喜欢，家庭的形成有这么多不同的方式。
I love that there are so many ways to make a family.
展开剩余字幕（还有 33 条）
我也是。
Me too.
感谢Anytime。
Thanks to Anytime.
所以莉齐、麦肯齐、露丝、阿尔奇、麦克、鲁本、卢安娜和格雷森，宝宝都是在妈妈身体里长大的。
So Lizzie, Mackenzie, Ruth, Archie, Mack, Reuben, Luana, and Grayson, babies grow inside the body.
在子宫里。
In the uterus.
一开始是一颗卵子和一个精子。
It starts with an egg and a sperm.
两个特别的细胞。
Two special cells.
它们带着DNA，里面藏着怎么长出一个身体的全部信息。
These cells carry DNA, the information on how to build a body.
卵子和精子结合在一起，形成一个新的
The egg and sperm cells join together to make one new
细胞。
cell.
受精。
Fertilization.
这个细胞一分为二，然后又分，再分。
That one cell splits to become two cells, and then it happens again.
再分。
And again.
再分。
And again.
再分。
And again.
直到
Until
变成胚胎。
they become an embryo.
胚胎会构建出身体的结构。
The embryo creates the structure of the body.
就像一幅画的草图一样。
Like an outline of a picture.
细胞读取DNA，互相传递信号。
Cells read the DNA and send messages to each other.
这里长出来。
Grow like here.
把大脑放这儿。
Put the brain there.
它们忙活着发育，直到变成胎儿。
They get busy making until a fetus grows.
这时候有草莓那么大了。
It's the size of a strawberry.
接下来几个月，胎盘会帮助胎儿继续长大。
Over months, the fetus will keep growing with the help of a placenta.
它提供氧气和营养。
It gives oxygen and food.
胎儿会越长越大。
The fetus will get bigger and bigger.
长得像芒果那么大。
As big as a mango.
再长到西瓜那么大。
And a watermelon.
虽然我们每个人来到这个世界的方式都不太一样，但一开始都是一样的。
Until we all come into the world a little differently, but we all start out the same.
从一个细胞开始，长成今天你身体里那几十亿、几万亿个细胞。
From the one single cell that grows to make the billions and trillions that make you today.
