First, my home has changed. We moved from a small flat to a bright apartment with a garden where I read and grow plants. Second, I no longer walk to school. My new school is far away, so I take the bus with my classmates every day. Third, my neighbourhood is nicer. In the past, there were only a few trees and no public parks nearby. But now, there is a lovely green space. Kids can run and play games there, and adults often take a relaxing walk after dinner. Although many things have changed, one thing has stayed the same: every evening, my family still gathers at the dinner table, happily chatting and sharing stories about our day. 板块三：Project ❶ Think of 10 things that are important in life Examples: technology, environment, transport, entertainment, education, shopping, housing, medical care, daily diet, public safety, study resources, travel ways, leisure activities, living accommodation, medical service, shopping methods, communication means, natural surroundings. Our 10 things: 1. __________ 2. __________ 3. __________ 4. __________ 5. __________ 6. __________ 7. __________ 8. __________ 9. __________ 10. __________ ❷ Design a survey 1. What was your daily diet like when you were my age? Could you eat your favorite food often? 2. What did you do to keep safe when you went out at night back then? 3. What learning materials could you use for your study when you were a student? 4. What transport did you take to get to school every day? How long was your commute? 5.

How? ❸ List the differences between their lives and your own Then Now Most people didn't have computers in their homes. Home computers are common, and many people use smart devices. People walked or cycled for school commutes with long travel times. Families have private cars, school buses and shared bikes. Festivals were almost the only chance to enjoy rich food. We can order takeout and buy fresh ingredients every day. People kept in touch only by handwritten letters. We make video calls and send messages instantly. Outdoor group games were the main leisure choices. We have mobile games, streaming shows, gym workouts and other leisure options. ❹ Presentation sample Good morning, everyone. Today I'll share the life differences between my mom's teenage years and my life now. First, let's talk about daily life and transportation. My mom walked 40 minutes to school every day, but I can take a convenient school bus and get to school in just 15 minutes. For food, she could only eat meat on big festivals, while I can have all kinds of tasty food whenever I want. Then about communication and entertainment. She wrote letters to contact faraway friends, but I can make video calls in seconds. Her free time was filled with outdoor games with neighbours, yet I could watch online courses, play mobile games or go to cinemas for fun. Housing and medical care have also changed a lot. Her big family squeezed into a tiny shared bungalow, but I have my own bright bedroom. Minor illnesses can be treated at nearby community hospitals easily now, while she had to travel far for better medical help back then. These changes make our life much more comfortable and convenient. I really appreciate the progress of our life. That's all for my presentation, thank you! 板块四：Reflecting 1.
