My grandma suggested drinking ginger tea, but I refused because its taste was too bitter. She told me it’s a magic natural food, and it is said that ginger can warm the body and relieve coughs. I decided to try it. Grandma boiled ginger with honey, and the smell was surprisingly nice. After drinking it for three days, my cough disappeared! I also searched online and found that ginger can also help with digestion. This experience teaches me that natural foods are full of surprises. It is true that many common plants around us have amazing health benefits. We should learn more about them and live a healthier life. 【译文】 发现天然食材的神奇功效 去年冬天，我得了重感冒，咳嗽不止——就像课本里张薇了解大蒜的那个场景一样。 奶奶建议我喝生姜茶，但我拒绝了，因为它的味道太苦了。她告诉我生姜是一种神奇的天然食材，而且据说生姜能驱寒、缓解咳嗽。我决定试一试。奶奶把生姜和蜂蜜一起煮，味道竟然出奇地好。喝了三天后，我的咳嗽就好了！我还在网上查了资料，发现生姜还能帮助消化。 这次经历让我明白，天然食材充满了惊喜。的确，我们身边很多常见的植物都有着惊人的健康功效。我们应该多了解它们，过更健康的生活。 亮点词块 1.natural food 天然食材 2.relieve coughs 缓解咳嗽 3.warm the body 驱寒 4.help with digestion 帮助消化 5.health benefits 健康功效 6.boiled ginger with honey 生姜煮蜂蜜 7.full of surprises 充满惊喜 高分句子 1.She told me it’s a magic natural food, and it is said that ginger can warm the body and relieve coughs.（运用it 作先行主语的主语从句，贴合单元语法重点） 2.It is true that many common plants around us have amazing health benefits.（再次运用主语从句，升华主题，贴合单元内涵） 3.Last winter, I caught a bad cold and couldn’t stop coughing—just like the situation in the textbook where Zhang Wei learned about garlic.（呼应课本主题场景，贴合单元核心话题） 【拓展1】 你的外国笔友Peter对中国传统天然食材很感兴趣，想了解它们的健康功效。请你写一封邮件，分享你发现某种天然食材神奇功效的经历，词数不少于60。 Dear Peter, I’m glad you’re interested in Chinese natural foods!
