2026年同步练习册智慧作业八年级英语下册人教版第45页答案
D
Here is a story: A man sees a butterfly. The butterfly tries to get out of its chrysalis(茧蛹). Feeling sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out easily. Surprisingly enough, the butterfly is unable to fly. If the butterfly doesn't struggle to leave the chrysalis, it can't fly! The struggle builds up the energy the butterfly needs to fly. Similarly, life's challenges bring out the best in young people and help them "spread their wings".
For young people, facing and overcoming challenges makes them strong and prepares them for life. When we look at successful people, we find that the most successful ones are those who have had to struggle. One famous businessman, who now owns many big supermarkets, used to carry clothes on his back and sell them door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. His father's passing forced him to mature(成熟) quickly. He had to support a family of nine. He faced challenges head-on and overcame them. Today, his brothers and sisters are all leading successful lives.
Sometimes challenges don't come our way because we shy away from them. That's why some parents and teachers encourage young people to face challenges. They might organize activities like rock-climbing, volunteer work, and more. However, just passing exams isn't enough to prepare someone for life. We must meet and overcome challenges. Today's young people will be tomorrow's leaders. To ensure our world keeps thriving for years to come, it's important that young people learn to face challenges and overcome them.
