(2025·南通市期中改编) As a middle school student, I 1. (not dream) of visiting other countries so far. The environmental ideas of 2. (Europe) countries also seemed too far away. But last summer, thanks to our school’s exchange programme, I had a chance 3. (visit) Germany.
Germany is famous for its green policies, especially in renewable energy. While walking through the Black Forest, we saw many people ride bicycles instead of driving. The 4. (beautiful) of the country amazed us. Locals told us, “The clean rivers you see today are not 5. they used to be, but through environmental reforms, 46% of our energy now comes from wind and solar power. So water pollution has been reduced by 60% over the past twenty years. It’s 6. (true) a great project.”
During the exchange programme, German students invited us to have a 7. (communicate) activity about recycling. One boy named Max even taught me to make bookmarks from 8. (fall) leaves. This trip was unforgettable and it also taught me that 9. (protect) the environment isn’t just about big ideas. If we all continue to do small things in our daily lives, our world will be a 10. (good) one.
