天气转冷 是时候来穿上厚厚的衣服 好好照顾自己了
When it gets cold outside, it’s time to bundle up and take good care of yourself.
Because cold-weather time is cold and flu season!
You’ve heard of colds — everyone gets them!
感冒的时候 你会打喷嚏 咳嗽 还可能会发热
That’s when you get sneezy, and cough-y, and maybe you’re running a temperature.
The flu is just another kind of cold, and it’s really no fun — it makes you
流感让人浑身酸痛 高烧不退 总之一副惨兮兮的样子
feel achy and sore, and hot, and all-around miserable.
But have you ever wondered what causes a cold and the flu?
Well, they’re both caused by something called a virus.
Viruses are very small…too small to see even with most microscopes.
They can make a big difference in your body, though, because they can make you sick!
是的 吱吱 既然病毒可以让我们生病那有时候我们也把它们叫做病菌
Yes, Squeaks, since viruses can make us sick, we sometimes call them germs.
But, not all germs are viruses… but the ones that can cause the flu and colds definitely are!
Now, in order to make you sick, the flu virus has to get into your body first.
它们通常从鼻子 嘴巴 眼睛等进入身体
It usually gets in through our nose…our mouth…or our eyes.
And once it gets in…the virus starts to make copies of itself until there are lots and lots
of them in there.
But don’t worry!
Your body has lots of ways to fight back!
It might seem kind of weird, but sometimes it’s the things that your body does to fight
the virus and other germs that makes you feel kind of yucky.
举个例子 比如黏液吧 就是那些从鼻子里流出来黏黏的东西
Take, for example, mucus …that’s the sticky, runny stuff that comes out of your nose.
Your bodies makes mucus to trap the flu virus and other germs that are in your nose and
When mucus runs out your nose, it carries the flu virus with it, along with other stuff
your body has used to knock them out!
Gross, maybe…but it works!
When mucus runs down the back of your throat, after a while it can make it hurt, too — that’s
why you sometimes get a sore throat when you’re sick.
然而 面对病毒 我们的身体并非只有用黏液冲走它们这一招
But washing out the virus isn’t the only thing your body can do to fight the flu!
好好想想 当我们生病时 还有一件什么事？
Can you think of another thing that most of do we’re not feeling very well?
说的对 吱吱 我们会打喷嚏
That’s right, Squeaks – we sneeze!
When you sneeze, air comes out of your mouth and throat really quickly.
As the air goes by, it picks up some of the virus pieces and carries them outside of your
因此 打喷嚏 就是我们的身体送病毒和细菌上路的好方法
So sneezing is your body’s way of sending viruses and other germs on their way!
Now, if you’ve ever had the flu, you probably know what a fever is!
A fever is another way that our bodies try to get rid of the virus.
When germs are inside your body, it can make itself hotter than normal.
And guess what?
Viruses hate that!
Because when it gets hot, it’s harder for the viruses to make copies of themselves.
And /that/ helps your body get rid of germs more easily!
So, your body has lots of cool ways to defend itself.
那么 在我们生病时 还有哪些办法可以让自己舒服一点呢？
But what else can you do to make yourself feel better when you get sick?
Well, getting lots of rest is one of the best things you can do when you’re not feeling well.
When you rest, you save energy — and your body can use that energy to get rid of the virus!
Another thing you can do is drink a lot.
健康的东西 比如说水 果汁 甚至是汤
Healthy things like water, some juices, and even soup will give your body the things it
needs to help you feeling better soon!
当然 最有效的措施是 不要生病
Of course, the best thing to do is to not get sick in the first place.
And to help with that, the number one thing to do is…
…wash your hands!
老生常谈的两样东西 温水和肥皂 就能帮助我们抵御疾病
Plain old warm water and soap can go a long way in keeping you from getting sick.
It’s especially important to wash your hands when you get home from school, or the store.
And remember how we said the flu virus often gets in through your nose, mouth, or eyes?
The other thing you can do is to keep your hands away from these parts of your body as
much as you can…even though it can be hard to remember to do sometimes!
And you can also keep of germs from spreading to other people by covering up your coughs
记住 在咳嗽和打喷嚏时 病菌会离开你的身体 传播到空气里去
Remember, germs are leaving your body and going into the air when you cough and sneeze.
So, if you can, cover your mouth and nose with a tissue, throw the tissue away, and
then wash your hands.
如果不能及时得到纸巾 那么请对着手肘咳嗽 而不是对着手掌
If you can’t get to a tissue in time, then cough into your elbow instead of your hands.
只要注意个人卫生 保持健康 你就能出门 尽情享受寒冷天气了！
So try to keep clean, and stay healthy, so you can go outside and enjoy the cold weather!
