We walked to the small shop near our block. The shopkeeper there is a kind old man. Grandpa took out his wallet and found only a little cash and one pound. 'Don't worry,' I said, and opened a payment app on my phone. The system received the money quickly, and grandpa paid for his breakfast in one second. He wanted to order fish and chips through the phone, because the delivery man could bring the food home. Later Mum used the oven to heat the dish, and nobody cooked except her. In this digital century, our city life is quite convenient. I often ride a shared bike to school. At school, our teacher will teach an online course when away. We check the homework on the class webpage anytime and anywhere. Internet education helps us make progress; a free lesson is a good first step. Even my little sister joins a fun activity at the weekend. But sometimes the network is offline, so we cannot watch the videos. In my opinion, the advantage of this new technology is that learning never stops. But new things also bring questions. Some people say the mobile phone has a bad effect on our eyes. My cousin was glued to his phone in his bedroom last night and played for three hours, so he had to charge his phone twice today. Via the Internet, anyone can read a great deal of news at home now. But some stories sound strange, and some of them are still not true, so each person should think twice. More than a million people read that news within one day. Last week a piece of news gave my grandpa a big shock, but in real life nothing had happened at all. B. 语境串记单词（汉语译文） 上周末，我在我们社区(neighbourhood)给爷爷演示怎么用智能手机(smartphone)付款(pay)。我们走到街区附近的小店，店主(shopkeeper)是位善良的老人。爷爷掏出钱包(wallet)，只找到一点现金(cash)和一英镑(pound)。「别担心，」我说着，在手机上打开了一款支付(payment)应用(app)。系统(system)很快(quickly)收到了钱，爷爷一秒钟就付好了早餐钱。他高兴得想通过这个应用点(order)炸鱼薯条，因为外卖配送(delivery)员能把食物送到家。后来(later)，妈妈用烤箱(oven)加热(heat)了菜，除了(except)她谁都不用做饭。 在这个数字(digital)世纪(century)，我们的城市生活相当方便(convenient)。我经常骑(ride)共享单车(shared bike)上学，父母坐地铁上班。在学校，科学老师外出旅行时能在线(online)教授(teach)我们课程(course)。我们随时(anytime)随地(anywhere)都能在班级网页上检查(check)作业。网络教育(education)帮助我们取得进步(progress)，一节免费课对初学者来说是很好的第一步(step)。就连(even)我妹妹周末也参加一些有趣的活动(activity)。但有时网络不在线(offline)，我们就看不了课程视频。在我看来，这项新科技(technology)的优点(advantage)是学习永不停止。 但新事物也带来问题。有人说手机(mobile)对我们的眼睛有坏影响(effect)。昨晚我表哥在卧室(bedroom)里盯着手机看(was glued to)，玩了三个小时，所以今天他不得不给手机充电(charge)两次。通过(via)互联网，任何人(anyone)现在在家都能读到大量(a great deal)新闻。但有些故事听起来奇怪(strange)，有些仍然(still)不是真的，所以每个人(person)都应该多思考。一天之内有一百多万(million)人读了那条新闻。上周一则新闻让爷爷大吃一惊(shock)，但现实(real)中根本什么都没发生。 第二部分：词形转变表 序号 原词 词形变化 1 pay v. 付款 payment n. 支付，付款 2 deliver v. 递送 delivery n. 递送 3 educate v. 教育 education n. 教育 4 shop v. 购物 shopkeeper n. 店主 / shopping n. 购物 5 quick adj. 快的 quickly adv. 很快，马上 6 convenient adj. 方便的 convenience n. 便利 7 digital adj. 数字的 digit n. 数字 8 order v. 点(菜) order n. 命令；顺序 9 check v. 检查 checkout n. 检验；结账台 10 real adj. 真实的 really adv. 真正地 / reality n. 现实 11 strange adj. 奇怪的 stranger n. 陌生人 / strangely adv. 奇怪地 12 teach v. 教 teacher n. 教师 第三部分：梯度复现与多题型练习 题型1：英汉互译（20题） 乐思英语 ·语境串记单词 1/8 学科网（北京）股份有限公司 子题A：英译中（12个） 1. digital → __________ 2. payment → __________ 3. delivery → __________ 4. education → __________ 5. advantage → __________ 6. effect → __________ 7. technology → __________ 8. progress → __________ 9. convenient → __________ 10. offline → __________ 11. shopkeeper → __________ 12. neighbourhood → __________ 子题B：中译英（8个） 1. 智能手机 → __________ 2. 钱包 → __________ 3. 现款，现金 → __________ 4. 应用程序 → __________ 5. 共享单车 → __________ 6. 课程 → __________ 7. 英镑 → __________ 8. 世纪 → __________ 题型2：词形变换（8题） 1.

I showed an old man how to pay with a smartphone at the small shop. The shopkeeper was kind, and the old man took out his wallet but had only a little cash and one pound. I opened a payment app, and the system received the money quickly. He paid for his breakfast in one second and wanted to order fish and chips. The delivery man could bring the food home later. Mum used the oven to heat the dish at home, and nobody cooked except her. In this digital century, city life is quite convenient. Many students ride a shared bike to school. Our teacher can teach an online course when away on a trip. We check homework anytime and anywhere on the webpage. Internet education helps us make progress; a free lesson is a good first step. Even my sister joins a fun activity at the weekend. Sometimes the network is offline, so we cannot watch the videos. In my opinion, the advantage of this new technology is that learning never stops. But new things also bring questions. Some say the mobile phone has a bad effect on our eyes. My brother was glued to his phone in his bedroom and played for three hours, so he had to charge it twice. Via the Internet, anyone can read a great deal of news at home. But some stories sound strange and are still not true, so each person should think twice. More than a million people read that news in one day. Last week a story gave my grandpa a big shock, but in real life nothing had happened. 1.
