模仿文本： In fact, we've got billions of friends in us. From our mouth to the end of our large intestine, all of us are the warm, wet and well-provisioned host to a remarkable ecosystem of microbes, many of which aren't just friends, but essential partners in our lives.

 

译文：事实上我们有数十亿的朋友在我们身体里。从我们的口腔到大肠末端，我们都是温暖潮湿、储备充足的主人招待着一个超大的微生物生态系统，其中一些微生物对于我们而言并不只是朋友，而是我们生命中必不可少的伙伴。
