Full Sample Answer (2+ minutes) 🎤

One invention that I believe has changed the world in an incredibly positive way is the internet 🌐. It is, without a doubt, one of the greatest technological advancements of the modern era. The internet has fundamentally transformed the way we communicate, learn, work, and entertain ourselves.

At its core, the internet allows people to access unlimited information 📚, communicate instantly 📞, and connect with the world 🌍. Whether it’s students researching for school, professionals attending online meetings, or families staying in touch across different countries, the internet has bridged the gap and made everything more convenient.

In terms of popularity, it is used by people of all ages and backgrounds 👶👴. Young children watch educational videos and play interactive games, while adults rely on it for work, social media, and shopping. Even the elderly use it to stay connected with their loved ones through video calls.

I believe the internet has changed the world in a profoundly positive way because it has democratized knowledge 🎓, expanded opportunities 💼, and brought people closer together ❤️. In the past, people had to rely on books and newspapers for information, which was often limited and outdated. Now, we can access real-time news and learn anything we want with just a few clicks!

Of course, like any invention, the internet has its downsides, such as cybercrime and misinformation, making it a double-edged sword ⚔️. However, when used wisely, I truly believe that it is one of the most powerful tools for progress, education, and global connection!

4. Do you think AI will replace human teachers? Why? 🤖👩‍🏫

Ideas 💡

• AI can assist teachers, but cannot replace human connection
• Emotional intelligence and motivation require human interaction
• AI is great for personalized learning, but teachers provide guidance & mentorship

Collocations 🌟

1. Lack human emotions 😕 (thiếu cảm xúc con người)
2. Offer personalized learning experiences 🎯 (cung cấp trải nghiệm học tập cá nhân hóa)
3. Play a supportive role 🤝 (đóng vai trò hỗ trợ)

Sample Answer 🎤

I believe that AI can assist teachers but will never fully replace them 🤖👩‍🏫. While AI can offer personalized learning experiences 🎯 and provide instant feedback, it lacks human emotions 😕, which are essential for motivation and understanding students’ needs. A good teacher doesn’t just deliver lessons—they inspire, guide, and support students in ways that technology simply cannot. So, while AI will play a supportive role 🤝 in education, human teachers will always be irreplaceable!
