Today, more and more kids are overweight （超重）. In China, one in ten kids has this problem.肥胖严重影响着儿童的健康。How can we keep fit?
Are you too heavy?
Let's take Nina as an example. Her height（身高） is 1.4 metres. Her weight（体重） is 50 kilograms. So: 50÷（1.4×1.4）=50÷1.96＝25.5
小于20 too thin
大于25 too heavy
Nina的检测结果高于25， 属于“超重”。She has to lose weight（减肥）!
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?
Mum gives me 20 yuan a week. 我把所有零花钱都用来买零食啦。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.
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，我就越不想动。Now I'm a couch potato. I don't know how to keep fit.
一对双胞胎，吃同样的饭菜，做同样的运动。One is too heavy. The other isn't. Why? 原来，肥胖除了和生活习惯、遗传有关外，还和新陈代谢能力有关。
