Why do you think these places changed so much? lead in eg:I see dry land and green land. I see shabby classrooms and modern classrooms. I see old green trains and modern high-speed trains. eg:People planted trees and protected the land. The government made their efforts to protect the land. People are more aware of protecting nature. Where is your hometown? Are there any changes in your hometown? lead in 01 · EDUCATION 03 / 08 From old Desks to Smart Classrooms Children once studied in drafty wooden shacks with cracked desks. Today, modern classrooms are equipped with interactive screens, VR headsets, and high-speed internet. THEN Blackboards · Shared books · Long walks to school NOW Smart screens · VR labs · Digital learning resources LEFT: a worn rural classroom. RIGHT: a modern VR-enabled classroom with immersive learning. 过去，孩子们就读于破旧的木制简陋校舍，课桌布满裂痕；而如今，现代化的教室配备了交互式屏幕、VR头显以及高速互联网。 lead in 从破旧课桌到智慧教室 1.7.2013 Look at this powerful side-by-side comparison. On the left, a typical rural classroom from decades ago — drafty, with broken wooden desks and a cracked blackboard. On the right, a modern smart classroom where students wear VR headsets and explore virtual worlds. The transformation is not just about buildings — it is about what children can imagine and reach. Today, even remote villages have access to digital learning resources that were unimaginable a generation ago. ‹#› 02 · HEALTHCARE 04 / 08 Four panels: early CT scanners vs. modern high-resolution MRI machines at a county hospital. From Stethoscopes to Precision Imaging Decades ago, a doctor relied on a stethoscope, blood pressure cuff, and thermometer — the "old three pieces." Today, even county hospitals have CT and MRI machines. THEN "Three pieces" only · Long travel for diagnosis NOW CT · MRI · Telemedicine close to home Photo: Yingjing County People's Hospital · Healthcare Development Over Four Decades 从听诊器到精准成像 几十年前，医生仅依赖听诊器、血压袖带和体温计——这被称为“旧三件套”；而如今，即便是在县级医院，也已配备了 CT 和 MRI 设备 lead in 1.7.2013 Healthcare is another area where the transformation is truly remarkable. Not long ago, local doctors only had the "three old pieces" — a stethoscope, blood pressure cuff, and thermometer. Patients had to travel for hours to the nearest city just for a basic scan. Today, the four-panel image on the left shows how county hospitals have moved from early CT scanners to modern high-resolution MRI machines. People no longer need to leave their hometown for advanced diagnosis — quality care is now available locally. ‹#› 03 · COMMUNICATION 05 / 08 From Letters and Pagers to Smartphones Old pager vs. modern smartphone 1978 · 1998 · 2018 — three decades of communication Once, families waited weeks for a letter. Then came pagers and brick-sized "mobile phones." Today, video calls connect relatives across the world in an instant. MAIL → PAGER → SMARTPHONE 曾几何时，家人会等待数周才收到一封家书；随后出现了寻呼机，以及砖头大小的“手机”；如今，视频通话已能让世界各地的亲人瞬间建立联系。 lead in 从信件与寻呼机到智能手机 1.7.2013 Communication is perhaps the most intimate change in daily life. A generation ago, sending a letter home meant waiting weeks for a reply. Then came the pager era — people rushed to find a public phone the moment the device beeped. The first "mobile phones" were heavy bricks that only the wealthy could afford. Today, every pocket holds a supercomputer. Video calls, instant messaging, and live streaming have made distance disappear entirely. The world feels smaller, but closer. ‹#› 04 · TRANSPORTATION 06 / 08 Top: steam-era station. Bottom: modern high-speed rail platform. From Slow Trains to High-Speed Rail Once, a trip home meant hours on a crowded green-skinned train. Today, high-speed rail covers hundreds of kilometers in comfort. Left: crowded spring festival travel in the 1980s. Right: orderly high-speed rail boarding today. lead in 从慢速列车到高速铁路 过去，回家一趟意味着要乘坐拥挤的绿皮火车数小时；而如今，高铁可舒适地覆盖数百公里的行程。 1.7.2013 Transportation is perhaps the most visible change. The left image shows the Huanggang Railway Station — the upper photo from the steam era, the lower from today's high-speed rail platform. For decades, traveling home for the Spring Festival meant squeezing onto a green-skinned train with thousands of others, often standing for hours. Today, the bottom image tells the new story: clean, quiet high-speed trains board in an orderly fashion. A journey that once took a full day now takes a few hours. Distance has collapsed. ‹#› 1a .图片中展示了哪些变化？ The photos show changes in Li Rui’s hometown over the years. What are the changes? How do they make you feel?
