I've been back in the UK for three days, but it feels like a century! It's amazing to see my family. Also, I really love Christmas and the delicious food. However, I've had some digital problems here. 先扬后抑，表达作者的真实生活感受。 中国高度依赖无现金支付，日常生活几乎不需要现金。英国虽然也有移动支付，但更依赖于信用卡、现金，作者遇到的digital problems暗含她对中国数字生态、科技效率的依赖。 2 Today, I wanted to get some vegetables and meat from a shop. I decided to ride a shared bike to get there. But it took forever to find a bike! I finally found an old one. But that 20-minute ride cost me an arm and a leg - 4.8 pounds! 用夸张的手法形容“找车久”。E.g. The bus took forever to come. It takes (sb)... to do sth意为"(某人)做某事花费了……(时间、金钱或努力等)”，这个结构中的it真正指代的内容是后面的to do sth。E.g. It takes me 20 minutes to get to work every day. / It takes a lot of patience to teach young children. 2 Today, I wanted to get some vegetables and meat from a shop. I decided to ride a shared bike to get there. But it took forever to find a bike! I finally found an old one. But that 20-minute ride cost me an arm and a leg —4.8 pounds! an arm and a leg是个英语习语，指很多钱。cost sb an arm and a leg意为“代价高昂，价格非常高”。句子中破折号后则补充说明了an arm and a leg的具体所指。 cost sb sth意为“花费某人……”，常用来表示花费钱、时间、精力等。E.g. The trip cost him all his savings. 3 In the shop, I quickly got everything I needed. I wanted to pay with my smartphone. I asked the shopkeeper to show the QR code, but she didn't understand! Next, I tried to use my digital wallet, but the shop's payment system didn't work. The shopkeeper told me to use cash. As I always make digital payments in China, I never carry my wallet. I had to go home to get some cash. 一些列动作清晰地描述了事件发展的过程，用两个but转折，突出冲突和无奈。 作者的情感从从容(quickly got everything)—焦急(tried to use)—无奈妥协(had to go home)变化自然，容易引起共鸣。 3 In the shop, I quickly got everything I needed.

The writer's digital shock in the UK Shared bikes was hard an arm and a leg Digital payment payment system cash app slow Think and Share 1. Why does the writer say that technology makes life more convenient in China? Because in China, mobile payment apps like Alipay and WeChat pay are widely accepted, however, in the UK, cash and credit card are still commonly used. In China, the shared bikes and other public transportation are easy to find and affordable（负担得起）, but in the UK, finding a shared bike is difficult and the cost is higher. In China, food delivery is fast and reliable（可靠的），but in the UK, the delivery is very slow. 2. Why do you think digital technology is so popular in China? Because it’s super convenient. You can pay for anything using your phone. No need to carry cash or card. Many young people in China love trying new technologies, so new apps and digital services spread very quickly. www.aliyun.com - Media Transcoding $
