参考答案及试题解析

Jenny knew she should just pick it up and return it to him, but she didn’t want to run after him. Jenny bent down quickly, picked up the watch and ran home. On arriving home, Jenny put it on almost without thinking. She was surprised it fitted so well. She walked to the mirror and started practicing her speech. Words just flooded out of her. “I’m going to talk about swimming. I have been lucky. I’ve won lots of competitions. But when I’m in a race, I’m not really thinking about winning. I’m just loving the feeling of being in the water...”Jenny laughed with excitement. She walked across the room. She suddenly seemed to have a certain sort of confidence. Turning back to the mirror, Jenny saw a flash of light from the watch in the glass. The flashes of silver seemed almost magical. So maybe Lee’s watch really DID have something magic.
The next day, as the lesson began, Miss Walker asked who was going to be brave and go first. No-body moved. Jenny slowly raised her arm. Before Miss Walker could say anything, there was a shout from behind. “She’s stolen my watch!” Lee said angrily, “It went missing at school yesterday.”
Paragraph 1: Everybody was fixing their eyes on Jenny, waiting for an explanation.
Paragraph2: At that moment, Miss Walker smiled and asked the class to listen to Jenny’s speech first.
范文
Everybody was fixing their eyes on Jenny, waiting for an explanation. Jenny's face paled, and her hands shook as she clutched the watch tightly. She bit her lower lip, trying to find the right words, but her throat felt dry and tight. Lee's eyes narrowed with anger, and he took a step forward, his fist clenched. "I saw it in your hand yesterday!" he shouted. Jenny's chin trembled, and she looked down at her feet, unable to meet anyone's gaze. The classroom was silent, and she could feel her heart thumping wildly in her chest. Just as she was about to burst into tears, Miss Walker's calm voice broke the tension.
At that moment, Miss Walker smiled and asked the class to listen to Jenny’s speech first. Jenny took a deep breath, her palms clammy with sweat. She stood up slowly, her legs feeling weak, and walked to the front of the class. As she looked up, she noticed the watch glinting on her wrist, and suddenly, the words came to her. "I want to talk about courage," she began, her voice steady. Her eyes sparkled with determination as she spoke, and she even gestured with her hands to emphasize her points. When she finished, the class erupted in applause. Lee's mouth dropped open in surprise, and a faint smile hovered on his face. Jenny took off the watch and handed it to him, her cheeks flushed but her head held high.
