1、意志细菌寰宇:看不见的生物、藏在饭菜中

2、学会食品保存:降温变质、巧用雪柜

3、养成卫生风气:勤洗手病、隔离坏菌

哎呀,你有莫得过这样的经验?早上姆妈给你作念了碗香喷喷的蛋炒饭,你急着去上学,就把它留在桌子上。比及下昼下学总结,你饿得肚子咕咕叫,开碗看——咦?怎样回事?炒饭闻起来有点怪怪的,上头概况还长了点绿绿的小毛毛。

Oh, have you ever had this happen? In the morning, your mom makes you a bowl of yummy egg fried rice. You are in a hurry to go to school, so you leave it on the table. When you come back from school in the afternoon, your tummy is rumbling with hunger. You open the bowl and look—huh? What's going on? The fried rice smells a little strange, and there seems to be some little green fuzzy stuff growing on top.

你皱着眉头凑近闻了闻,“哇,这滋味…”难吃得你连忙把碗开了。未必刻啊,你可能会听到奶奶或者姆妈慨气说:“哎,天气太热了,饭菜容易馊掉。”馊掉是什么事理呢?即是饭菜变坏了、变臭了,不可再吃啦。

You wrinkle your nose and lean in to sniff. "Wow, this smell..." It tastes so bad that you quickly push the bowl away. Sometimes, you might hear your grandma or mommy sigh and say, "Oh, it's so hot. The food can go bad easily." What does "go bad" mean? It means the food has turned yucky and smelly, and you can't eat it anymore.

然而,为什么天气热,饭菜就这样不听话呢?小凉菜、红肉、白米饭,它们明明好好的,怎样就一刹变得让东说念主念念潜逃呢?别急,我们逐渐来猜猜看。你知说念吗,其实饭菜内部住着许多许多看不见的小住户。

But why, when the weather gets hot, does the food become so naughty? The little cold dishes, the red-braised meat, the white rice — they were all fine just a moment ago. Why do they suddenly make us want to run away? Don’t worry. Let’s take our time and guess. You know, there are actually many, many tiny invisible residents living inside the food.

它们超越小超越小,小到什么进度呢?你用眼睛看,压根看不到;用鼻子闻嘛,未必刻也闻不到。得用放大镜,致使锐利的显微镜才气瞧见。这些小住户的名字叫——细菌。“细菌?听着好啊!”你可能会这样念念。

They are very, very tiny. How tiny? You cannot see them with your eyes. Sometimes you cannot even smell them with your nose. You need a magnifying glass, or an even stronger microscope, to find them. These little residents are called — bacteria. "Bacteria? That sounds so scary!" you might think.

其实呀,不是系数细菌齐是坏的。有些细菌还帮我们作念酸奶、发面团呢。但有些小伙,超越可爱干预。它们趁我们不防备,悄悄溜进饭菜里,驱动大口大口地吃啊、喝啊,然青年许多许多宝宝。

You know, not all germs are bad. Some germs even help us make yogurt and make dough rise. But there are some little ones that really like to cause trouble. They sneak into our food when we're not paying attention. They start gobbling up food and drinks, and then they have lots and lots of babies.

等你发现的时刻,它们照旧堵满了整碗饭,吃得饱饱的,还拉出些臭臭的东西。那些臭臭的东西啊,即是让你闻到怪味、饭菜变馊的“首恶祸”。但是,为什么天热的时刻,细菌就超越捣蛋呢?

By the time you see them, they’ve already filled the whole bowl of rice. They eat until they’re full and then make some stinky, yucky stuff. That stinky stuff is the real troublemaker — it’s what makes your food smell funny and go bad. But why do germs love to be so naughty when the weather is hot?

我们来个比吧。你有过在雪地里玩雪的经验吗?冬天的时刻,外面超越冷,你穿得像个小熊样,如故冻得直发抖。其时刻,你念念跑啊、跳啊,齐认为好累,作为慢吞吞的。细菌也差未几。

Let's imagine something together. Have you ever played in the snow? In winter, it is very, very cold outside. You put on thick clothes and look like a cute little bear. But you still shiver and shake. You want to run and jump, but you feel so tired. You move slowly, like a sleepy snail. Well, germs are a lot like that too.

冬天天气冷,这些小伙就像被冻僵了似的,顾后瞻前的,动齐懒得动潍坊隔热条设备厂家家,别说跑去饭菜里大吃大喝了。是以冬天的饭菜,放天可能也没什么大事儿。然而夏天呢?我的天!

In winter, it is very cold. These little critters are like they are frozen. They curl up tight and do not want to move at all. They do not even want to run to the food and eat a lot. So in winter, food can sit out all day and nothing really happens. But in summer? Oh my!

太阳火辣辣的,热得你恨不得整天齐泡在游池塘里。这时刻的细菌们,就像刚从蛰伏中醒过来样,精神超越好!“哇,太棒啦!天热,我们起开派对!”它们狂地爬啊、跑啊、飞啊,找到你吃剩的饭菜,险些像发现了矿藏。

The sun is so hot and strong. It makes you want to stay in the swimming pool all day long. At this time, the germs are like they just woke up from a long nap. They are full of energy! "Wow, this is great! It’s hot — let’s have a party!" They crawl, run, and fly around like crazy. When they find your leftover food, they act like they just found treasure.

它们爬进米饭里,钻进菜汤里,在肉块上连蹦带跳,边吃边生宝宝,速率快得不行——你能念念象吗?个细菌宝宝,惟有环境适,过个十几二额外钟,它就能造成两个;再过会儿,两个变四个;四个变八个…哎呀,险些比变魔术还快!

They crawl into the rice. They squeeze into the soup. They hop and jump on the meat. They eat and have babies at the same time — so, so fast! Can you imagine? One little germ baby, if the place is just right, in about ten or twenty minutes, it can turn into two. A little later, two become four. Four become eight… Wow, it’s even faster than magic!

几个小时以前,你碗里的细菌可能比全寰宇的东说念主口还要多!是以啊,天气越热,细菌越怡悦,它们繁衍得越快,饭菜馊得也越快!你可能会问:“那为什么雪柜里的饭菜就阻扰易馊呢?”哈哈,这个问题问得好。

After just a few hours, the germs in your bowl could outnumber all the people in the whole world! So, the hotter the weather, the more excited the germs get. They multiply super fast, and your food goes bad much quicker! You might ask, "Then why doesn't food in the fridge spoil so easily?" Haha, that's a very good question.

雪柜里的温度很低,就像把细菌丢进了冰寒的冬天,它们下就顾后瞻前,慢下来了,隔热条PA66生产设备致使许多坏伙齐被冻得不敢动了。是以饭菜放雪柜里,就能多保存几天。不外,也有小一又友会问:“我前次把饭放在空调房里,也没馊啊!”

The inside of a fridge is very cold. It's like throwing germs into a freezing winter. They quickly become slow and stiff. Even many bad germs are frozen and too scared to move. So潍坊隔热条设备厂家家, food in the fridge can stay fresh a few more days. But some kids may ask, "Last time, I left my rice in the air-conditioned room, and it didn't go bad!"

嗯,空调房里比外面凉快,是以细菌活动会慢些。但也不是对安全的哦。因为空调房里的温度还不够低,挡不住超越闹的那些细菌。是以好的方针啊,如故吃不完的饭菜连忙放雪柜。

Well, an air-conditioned room is cooler than outside, so germs move more slowly. But it’s not completely safe. The room is not cold enough to stop very active germs. So the best way is to put leftover food into the fridge quickly.

未必刻,你可能会看到菜汤上漂着层细细的东西,或者米饭变黏黏的、拉丝了。那齐是细菌们在开派对留住的陈迹。它们把正本健康的饭菜,造成了让东说念主肚子疼的坏蛋。是以,如果饭菜闻起来怪怪的、看起来分手劲,千万别念念吃吃看,连忙倒掉,还要洗干净碗。

Sometimes, you might see a thin layer floating on your soup, or your rice might get sticky and stringy. That's the mess left by bacteria having a party. They turn fresh food into yucky stuff that can give you a tummy ache. So, if the food smells strange or looks weird, don't taste it. Throw it away quickly, and wash your bowl clean.

你猜怎样着?其实细菌不光可爱热,还可爱湿气。夏天又热又潮,就像个慈悲的游水馆,细菌在内部游来游去,玩得别提多欣喜了。是以夏天的时刻,厨房里的抹布、案板、还有你吃生果的盘子,齐要接续洗干净、晒干,否则也会长出细菌,让我们生病。

Guess what? Bacteria not only like heat—they also like wet places. Summer is hot and humid. It’s like a warm swimming pool. Bacteria swim around and have so much fun there. So in summer, kitchen towels, cutting boards, and the plates you use for fruit must be washed often and dried well. If not, bacteria can grow and make us sick.

有些小一又友吃完西瓜肚子疼,很可能即是因为西瓜切怒放深刻,细菌悄悄爬上去玩了个欢欣。好啦,目下你显明了吧?饭菜馊掉,不是因为饭菜我方不满了,也不是什么魔法捣的鬼。

Some kids get a tummy ache after eating watermelon. That’s usually because the watermelon was cut and left out too long. Germs quietly climbed on it and had a little party. Okay, now you know why, right? When food goes bad, it’s not because the food gets angry. And it’s not a magic trick!

它是因为天气热的时刻,细菌们太活跃了,它们跑来跑去,又是吃又是生宝宝,还制造出怪味来。是以,下次你不错赋闲肠告诉姆妈:“我知说念为什么饭菜会馊了——是天太热,细菌在开派对呢!”

It's because when the weather is hot, germs get very busy. They run around, eat, have babies, and make yucky smells. So next time, you can proudly tell your mom, "I know why the food goes bad — it's too hot and the germs are having a party!"

不外,别光知说念了这个机密,还要动手作念点什么。比如,吃饭的时刻,尽量吃完,不要剩太多。如确实的有剩菜,别盘桓,连忙放进雪柜。还有,吃饭前铭记洗干净手,因为手上也可能藏着看不见的细菌小来宾呢!

But don't just know this secret—you should do something, too! For example, when you eat, try to finish your food and don't leave too much. If you really have leftovers, don't wait—put them in the fridge right away. Also, remember to wash your hands before eating, because your hands might be hiding some invisible little germ guests!

念念念念看,其实细菌也挺折腾的。它们那么小,要辛勤找吃的,怕冷又怕热。然而啊,我们不可让它们在我们吃的饭菜里开派对,对吧?我们要当饭菜的“小卫士”,保护好我们的食品,不让坏细菌干预。这样,饭菜就能香香的、安全的进到我们的肚子里,给我们力气和痛快。

Think about it. Germs have a pretty hard life, too. They are so small. They try hard to find food, and they don't like being too cold or too hot. But we can't let them have a party in our meals, right? We have to be little food protectors. We must keep our food safe from bad germs. Then our food stays yummy and clean. It goes into our tummies and gives us energy and joy.

如果有天,你看到碗摆在太阳下面的饭菜,你不错悄悄摸摸地凑近它,小声告诉它:“别怕,我去把你放进雪柜里,保护你!”然后,你就帮了它个大忙。因为雪柜固然冷飕飕的,但对饭菜来说,那是它的安全屋呀!

If one day, you see a bowl of food sitting under the sun, you can tiptoe close to it. Whisper to it, “Don’t be scared. I’ll put you in the fridge and keep you safe!” Then, you’ve done it a big favor. The fridge might feel cold, but to the food, it’s a safe little home.

对啦,如若你里养了小猫小狗,也别让它们吃馊了的饭菜哦。它们也会肚子疼的。你不错领导里东说念主,巨额防备下,就不会有吃到馊饭的危急了。好啦,这个故事就讲到这里。
