null望踏上思念路。千里山，归雁披残霞，乡关在何方？吹老了岁月，吹不老我的思。历经多少个今夜梦回清关。上天和太阳肩并肩，在等着我去想做的梦，从不怕别人看见，在这里都能实现。大声欢笑，让你我肩并肩。抛开烦恼，勇敢的大步向前，我就站在舞台中间，我相信我就是我，我相信明天，我相信青春没有你。都是我心中。 The changing world Unit 1 Section B (2a-3d) 2a Use a word on the left and a word on the right to create a compound word.

To begin with, the place where I live is quite different now. In the past,my family stayed in a small flat and we didn‘t have many things. Today, we live in a much larger flat filled with more belongings and useful gadgets. Our home feels more spacious and modern than it used to. My school experience has changed a lot as well. When I was younger, I walked to my primary school and enjoyed studying there. Now I am a student in junior highschool, and there are more choices and better facilities to support my learning. Every morning, I take the subway to get there. It takes less time and is more convenient for me. We also have computer rooms that help us explore new ways of learning. There are also differences in how I study. Before, I mainly used books and pencils to study. These days, I learn with computers, tablets, and various online resources. They help me study more efficiently and make learning more enjoyable. Many aspects of my life have changed, but something important remains the same: I still look forward to learning and discovering new things every day.

As for entertainment, modern cinemas offer better viewing experiences, and people are taking part in more outdoor activities to keep healthy. The area where I live used to be filled with small and old houses. But now people live in tall buildings. The environment has also improved greatly, with more green parks.

They have made my life more convenient and enjoyable, and I am proud of the progress my community has made. 范文2 My changes Hello, I'm Li Hua. Today I will talk about my changes. In the world, the only unchanged is changing. Over the past two years, I've seen great improvements in my physical fitness, learning methods, living habits, and social skills. Physically, I used to be inactive and seldom exercised, but now I keep doing sports regularly, boosting my health and confidence. In my study, I moved from passive learning to actively seeking resources and joining in discussions, improving my understanding and performance. My living habits have also improved. I now follow a routine with regular sleep and study times, leading to a more balanced and less stressful life. Socially, I've gotten over shyness by joining in school activities, improving my communication skills and building stronger friendships. These changes require effort and hard work, but they have transformed me into a more confident and excellent person. Thank you for listening! SEE YOU $
