　　Part 2 Check-it-out 趁热打铁

　　To eat or not? 吃还是不吃呢？

　　Simple and plain /ple?n/ food is often the best but it is not always true. For many of us food is a need. For others, food is a friend. And to some others, food is an enemy /?en?mi/ .

　　简单朴实的食物最好的，但是这个理论偶尔也不对。对于很多人来说，食物是基本需求。但是对于有些人来说，食物是朋友。对其他人来讲，食物是敌人。

　　Let’s say you’re feeling down. You had a tough day or a fight with a best friend. You decide to treat yourself to a bar of chocolate –nothing like chocolate could cheer you up.

　　假如你心情不好。一整天过得不开心或者跟朋友吵了一架。你决定奖励自己一块巧克力--没有什么食物更能比巧克力更能使人开心了。

　　But you’re getting a lot of calories /?k?l?ri/. That’s because chocolate /?t?ɑ:kl?t/ bars have much fat and sugar. They are going to take a long time to get out of your body. And caffeine /?k?fi:n/ in the chocolate will make you feel happy and relaxed for a while but it will make you feel bad when you’re getting fat.

　　但是不幸的是，你将会吸收很多卡路里。那是因为巧克力含有大量的脂肪和糖类。他们会在人体内部停留很长时间。巧克力中的咖啡因会在短时间内使得你感到幸福和放松，但是最后当你开始变胖的时候，你就会感觉比较槽糕。
