2026年阳光假日暑假七年级英语外研版第51页答案
B
When cultures meet, not just their language or clothing may be different. Often their food will be greatly different too. People on both sides can discover new chances for trading. This text tells how some common food plants spread around the world.
As early as 5,000 BC, potatoes were used in South America as a valuable type of food. They were taken to Europe in the 1500s and their use soon spread across it.
Tea drinking started in China. By the early 1600s, traders had begun to ship tea from China to Europe. Tea drinking soon became fashionable there but because of its high price, it remained a drink for the wealthy.
Sugar cane(甘蔗) was first used to produce a kind of sweet juice over 8,000 years ago on the island of New Guinea. Its use soon spread across South East Asia and then to the wider world.
Cocoa(可可粉) was used to make a cold, spicy drink in Central America over 3,000 years ago. The Europeans brought it back with them in the 1520s and added sugar to make the sweet, hot drink we know today. Though it's expensive, many people still love it.
Cultural exchanges are like a warm bridge for food plants. They carry potatoes, tea and other delicious foods to tables around the world, making our diets more colourful and connecting different places closely.
