Unit 45 Steer clear of junk foods.

　　Unit 45 与垃圾食物划清界限

　　They're not really foods,anyway,Chips,dips,crunchies,munchies-sounds like something you throw to the animals at the zoo.Junk food is low in nutrition high in calories and almost guaranted to pack on the pounds.

　　反正它们也称不上是真正的食物。洋芋片、沾酱、脆片、脆饼-听起来好像那些你丢给动物园里的动物吃的东西。垃圾食物营养价值低，卡路里高，而且保证几乎全是大包装的。

　　健身短语
