I'm a Virus!

我是病毒！

Hi there! I'm Virus! No, not her. That's my hostess with the mostest. She has the sniffles. Whee! Off to a new host. I am not alone. Each virus particle is called a virion. Lots of us fly in droplets of snot to...

大家好!我是病毒!不，不是她。 这是我最喜欢的女主人。 她流鼻涕。哟!去找一个新的主持人。 我并不孤单。每个病毒粒子称为一个病毒粒子。 我们很多人乘飞机飞到…

your nose! Zoom in. Closer. That's a nose hair. That's a booger. nose hair booger Closer. Closer. You have trillions of cells. They are so small they can only be seen under a microscope. But together, they make up your body, from your blood to your bones and even the inside of your nose! me cells

你的鼻子!放大。近了。 那是鼻毛。那是鼻屎。 鼻毛鼻屎靠近点。近了。 你有数万亿个细胞。 它们很小，只有在显微镜下才能看到。 但它们共同构成了你的身体，从你的血液到你的骨头，甚至你的鼻子里面！我的细胞

This is Cell. And this is its friend Snot Cell. Snot Cell makes— you guessed it-snot! Cell pumps that snot away with hairlike things called cilia. me SNOT CELL CELL cilia nuclei *The parts of cells that tell cells what to do—like make more of me! Shhhh... don't tell Cell, but I am here to attack it. I am a rhinovirus. Rhino means "nose." I invade nose cells to cause the common cold.

我是Cell。这是它的朋友鼻涕细胞。 鼻涕细胞制造——你猜对了——鼻涕！细胞用毛发状的东西把鼻涕吸走，叫做纤毛。 细胞细胞纤毛细胞核*细胞的部分，告诉细胞做什么-使我更多！嘘…… 别告诉细胞，但我是来攻击它的。 我是鼻病毒。Rhino的意思是“鼻子”。 我侵入鼻腔细胞引起普通感冒。

I'm pretty simple, really—a strand of RNA surrounded by a spiky protein shell. My spikes fit perfectly onto Cell's surface. You might say we are a perfect match—like a key in a lock. Cell opens up and lets me in. virus receptor click Then I shrug off my spiky jacket so RNA can do its job. Off it goes to deliver its chemical code message to Cell: Make more of me. Lots more! RNA

我很简单，真的——一条被尖尖的蛋白质外壳包围的RNA链。 我的刺钉和“细胞”的表面完全吻合。 你可以说我们是天作之合，就像一把钥匙开在锁里。 牢房打开了，让我进去了。 然后我脱掉带刺的外套，让RNA来完成它的工作。 它开始向细胞传递它的化学密码：制造更多的我。 更多!核糖核酸

Uh-oh! It's getting crowded in here. Pop! Er, sorry about that, Cell. Now even more of us can... ATTACK! ATTACK! ATTACK!

啊哦!这里越来越拥挤了。 流行!不好意思，Cell。 现在更多的人可以…… 攻击!攻击!攻击!
