許昌翻譯公司看微細(xì)菌
you are full of bugs.
你身上好多細(xì)菌！
No, not cockroaches and ants. These bugs are tiny, single-celled bacteria you can't see. They blanket your skin. They also fill your stomach, intestines, lungs and mouth.
它們既不是蟑螂也不是螞蟻，這些小蟲(chóng)子很小，肉眼難見(jiàn)的單細(xì)胞細(xì)菌，它們不僅覆蓋在你的皮膚上，而且也出沒(méi)于你的胃、腸、肺口腔內(nèi)。
In fact, roughly 100 trillion of these microscopic critters live in (and on) the human body. A typical person contains only about 37 trillion human cells. In other words, bacteria might outnumber human cells in an average person by roughly three to one.
事實(shí)上將近約100萬(wàn)億此類(lèi)微生物寄居在你的身體內(nèi)外。一個(gè)人僅有37萬(wàn)億人類(lèi)細(xì)胞。換句話(huà)說(shuō)，人類(lèi)身體上的細(xì)菌遠(yuǎn)遠(yuǎn)超出了細(xì)胞數(shù)量以1:3的比例存在著。

Bacterial cells are very small. All of these bugs make up only between 1 and 3 percent of your body weight.
細(xì)菌細(xì)胞非常小。但是這些討厭鬼足足占了你體重的1%到3%呢！
We even pick up bacteria from family members - for example, when someone kisses us on the cheek.
此外，這些細(xì)菌還會(huì)通過(guò)家人侵入我們的身體-例如，有人親你臉蛋的時(shí)候。
You pick up some microbes from your mother during birth. As you grow, your body acquires more. For example, new microbes hop on when you play in the dirt or when a family member kisses your cheek.
分娩的時(shí)候媽媽便給寶寶留下了這些微小細(xì)菌，隨著你長(zhǎng)大，你身上的細(xì)菌會(huì)變得更多。比如說(shuō)，當(dāng)你在較臟的環(huán)境下玩耍的時(shí)候或者家人親親臉蛋時(shí)這些細(xì)菌都會(huì)趁虛而入。
At this point, you might be starting to wish you could get rid of all those germs. But that wouldn't be a very good idea. The microbes in your body are crucial to your health. They churn out nourishing vitamins. They help digest your food. Some even keep other, dangerous bacteria from multiplying so you don't get sick.
如此說(shuō)來(lái)，你可能開(kāi)始想要擺脫這些細(xì)菌。這種做法不太明智，因?yàn)檫@些細(xì)菌對(duì)你的健康還起著至關(guān)重要的作用，比如說(shuō)他們會(huì)產(chǎn)出富含營(yíng)養(yǎng)的維他命，幫助你消化食物，有的甚至還阻止其他危險(xiǎn)細(xì)菌的繁殖來(lái)幫助你躲過(guò)感冒一劫。
In return, the bacteria get nutrients and a place to live. "It's a tit for tat," says Margaret McFall-Ngai. She is a microbiologist at the University of Wisconsin-Madison.
對(duì)于細(xì)菌而言，我們?yōu)槠涮峁I(yíng)養(yǎng)以及居所作為回報(bào)。美國(guó)威斯康星大學(xué)微生物學(xué)家Margaret McFall-Ngai無(wú)奈的感慨道：對(duì)于我們來(lái)說(shuō)微生物細(xì)菌是一柄雙刃劍！
