Today， more and more kids are overweight（超重）. In China， one in ten kids has this problem. 肥胖嚴(yán)重影響著孩子的健康。How can we keep fit?

Are you too heavy?

按照下面這個(gè)公式來檢測一下吧。

體重÷（身高×身高）＝結(jié)果

Let's take Nina as an example. Her height（身高）is 1.4 metres. Her weight（體重）is 50 kilograms. So: 50÷（1.4×1.4）=50÷1.96＝25.5

結(jié)果是多少

小于20 too thin

20~25 good

大于25 too heavy

Nina的檢測結(jié)果高于25，屬于“超重”。She has to lose weight（減肥）!

What about you?

Ask your best friend to do the test. If he/she is too heavy， give him/her some advice.

Why do we get fat?

Nina 我就愛吃零食

Mum gives me 20 yuan a week. 我把所有零花錢都用來買零食啦。I like eating. Chips are my favourite. When I'm hungry， I eat them. When I'm not hungry but have nothing else to do， I eat them too. Mum asks me to stop eating like that， but I don't listen. Now， I can't run fast. Maybe mum is right.

Sam 動(dòng)都不想動(dòng)

I don't like swimming. I don't like playing football. What I like is to lie on the couch and watch TV. Cartoons are my favourite. I'm getting heavier. 越胖，我就越不想動(dòng)。Now I'm a couch potato. I don't know how to keep fit.

一對(duì)雙胞胎，吃同樣的飯菜，做同樣的運(yùn)動(dòng)。One is too heavy. The other isn't. Why? 原來，肥胖除了和生活習(xí)慣、遺傳有關(guān)外，還和新陳代謝能力有關(guān)。
