Part 2 Check-it-out 趁熱打鐵
To eat or not? 吃還是不吃呢？
Simple and plain /pleɪn/ 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 /ˈenəmi/ .
簡單樸實的食物最好的，但是這個理論偶爾也不對。對于很多人來說，食物是基本需求。但是對于有些人來說，食物是朋友。對其他人來講，食物是敵人。
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。一整天過得不開心或者跟朋友吵了一架。你決定獎勵自己一塊巧克力--沒有什么食物更能比巧克力更能使人開心了。
But you’re getting a lot of calories /ˈkæləri/. That’s because chocolate /ˈtʃɑ:klət/ bars have much fat and sugar. They are going to take a long time to get out of your body. And caffeine /ˈkæfi: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，你將會吸收很多卡路里。那是因為巧克力含有大量的脂肪和糖類。他們會在人體內部停留很長時間。巧克力中的咖啡因會在短時間內使得你感到幸福和放松，但是最后當你開始變胖的時候，你就會感覺比較槽糕。
