No one lives without food. For centuries, people grew their own food and (吃) it themselves. But now most people buy food in shops and (超市). The next time you have dinner, look (近) at the food on your plate. If you're dining in summer, it's possible that some of the food comes from small (私人) farms, but more of it comes from large farms and companies.
How do you know where your food is from? You can check by (你自己). Most food gives information on its packet. And you may be surprised at what you (收集) because it comes from places around the world. You can enjoy a(n) (柑橘；橙) from South Africa and a tomato from Mexico. You can (甚至) enjoy a pizza from Italy. And you needn't travel to these places. Instead, the food travels to you.
Thanks to modern trucks, trains, ships, and (飞机) , the food travels fast. So the food is still (新鲜) and healthy when it reaches your dinner table. Also, new technology helps the food last long while it travels.
