Presentation 1.Look at the picture and answer the questions. (课本活动1) 1）What differences between the lives of ancient people and ours do you know 答案： 不同点1：Ancient: People walked, rode horses, used animal carts, or sailed boats. Travel was slow and dangerous (e.g., months to cross a country). Now: We have cars, bullet trains, airplanes, and electric scooters. We can travel across the world in one day! 不同点2：Ancient: People sent letters by hand or messenger. News took weeks or months to arrive. Now: We use phones, internet, social media, and video calls. We can talk to anyone on Earth instantly! 不同点3：Ancient: Cooked over fire, fetched water from wells, used candles for light, washed clothes in rivers. Now: We use electric stoves, refrigerators, light bulbs, running water, and washing machines. Life is much easier and faster! 2）What caused these differences 答案： The biggest reason is the development of science and technology! Our lives are faster, easier, healthier, and more connected than ancient times because of hundreds of years of scientific discoveries and technological inventions! 2. Look at the pictures and answer the questions. (课本活动2) 1）What are these inventions 2）How have they changed our lives 发明1：Safer Sea Travel: It helped ships find their direction, even far from land or in bad weather. This made ocean travel much safer. Exploration: Sailors could explore new lands across huge oceans because they wouldn't get lost easily. This connected the world. Finding the Way: It gave people a reliable way to know which direction was North, South, East, or West anywhere on Earth, not just at sea. Science & Maps: It helped people make better maps and learn more about navigation (finding the way) and the Earth itself. 发明2：1.Easier to Move Heavy Things: Before wheels, people carried or dragged heavy objects (like stones or crops). Wheels made it much easier to pull heavy loads. 2.Faster Travel & Transport: Carts with wheels could carry people and goods faster and further than walking or carrying by hand. 3.Basis for Future Inventions: The simple wooden wheel was the starting point for all the wheels we use today (on cars, bikes, machines, etc.). 发明3：1.Fast Information: Computers let us find information very quickly, like using the Internet instead of big books. 2.Easy Communication: We can talk to people anywhere instantly using email, messages, or video calls. 3. Entertainment: We use computers for watching movies, listening to music, and playing games. 4. Storing Things: Computers can keep huge amounts of photos, music, documents, and videos safely. 发明4：1.Always Connected: We can call or text people anytime, nywhere, not just from home. (Connected - 保持联系) 2.Easy Payments: In many places, we can pay for things in shops or order food just by using our phone. (Payments - 支付) 3.Entertainment On the Go: We can listen to music, watch videos, or play games while waiting for the bus or traveling. (Entertainment - 娱乐)
