Part 2: 场景化助学短文
（读文章，结合语境，写出加粗词汇含义）
On a rainy weekday, Tom hurried to school. He had to arrive on time because there was an important exam. In the hallway, he almost slipped on a sweet wrapper someone had littered. "This is awful!" he thought. If people don't treat the school with respect, how can we build a good learning environment
During the break, Tom's friend asked to lend him a pencil. "Of course," said Tom. The teacher reminded everyone: "Focus on your papers, and turn off your mobile phones." After school, Tom met Dr. Chen at the clinic. The doctor gave him advice: "Practise deep breathing to relax when stressed." Walking home, Tom saw people queuing politely for buses. No one tried to jump the queue – it showed the city's spirit of mutual respect.
That night, Tom hung his wet jacket to dry and made the bed neatly. He thought about his dream to become an architect. "I need to understand math better," he decided. Before sleeping, he smiled: "Every person can build a wonderful future if they work hard!"
