空气差，体变胖

Air might lead to obesityy

To make the things we talk about more vivid，rhetoric is often used.For example，when seeing a friend or a person we know whose body becomes huge in a short period of time，we would say he is just like a balloon full of air. Here metaphor and exaggeration are adopted.

But the reality is that air does have some effect on body figure.

Breathing in and out is the thing we do every minute. And without air we won’t live long.But that life-giving air might just be pushing you towards diabetes and obesity.

Two people can eat the same foods，and do the same exercise，but over the course of a few years，one may put on more weight and develop a faulty metabolism thanks to the atmosphere around their home.

Traffic fumes and cigarette smoke are the chief concerns，with their tiny，irritating particles that trigger widespread inflammation and disrupt the body’s ability to burn energy.

Researchers did experiment with laboratory mice. They divided mice into two groups.Some breathed filtered，clean，air，while others had to live with the kinds of fumes you might find next to a motorway or busy city centre.

After just 10 weeks，the effects were already visible. The mice exposed to the air pollution showed greater volumes of body fat，both around the belly and around the internal organs.What’s more，they seemed to have become less sensitive to insulin the hormone that signals to cells to convert blood sugar into energy.

为了让描述的事物更加生动形象，我们经常用到修辞。比如：看到朋友或熟人突然发福，我们会说他就像“充满气的气球”。这里使用了比喻和夸张。

但现实是，空气真的会影响我们的体型。

我们每时每刻都在呼吸，离开了空气，我们无法生存。但是，我们赖以为生的空气可能引起糖尿病和肥胖。

让两个人吃一样的食物，进行一样的锻炼，但是几年后，其中的一个可能因为自己周围的空气而重量增加，新陈代谢变差。

研究人员用小白鼠进行了实验。他们把小白鼠分为两组。一组呼吸经过过滤的、干净的空气；另一组则生活在类似于机动车道或者城市中心空气的环境中。

仅仅10周后，效果开始显现。呼吸污染空气的小白鼠胖了很多，腹部和体内器官都有脂肪增加。更重要的是，这些小白鼠似乎对胰岛素已经不太敏感，而胰岛素的作用就是指示细胞把血糖转换为能量。
