Unlike her junior high school, where she had been one of the top students, here everyone seemed more confident and better prepared. She worried that she would fail to impress anyone. During the first week, Sarah found it hard to concentrate in class. Her mind kept wandering back to her old school and friends. However, a turning point came when her English teacher, Mr. Thompson, announced a group project that required students to explore a topic of personal interest and present their findings formally to the class. Sarah, driven by curiosity, chose to research how music affects learning. She was eager to discover whether listening to music could actually help students improve their memory and concentration. Her group partner, David, was well-organised and kept good company during long study sessions in the library. As they worked together, Sarah's confidence grew steadily. She discovered that having a supportive partner made a significant difference — it turned a daunting task into an exciting journey of exploration. When they finally delivered their presentation, Mr. Thompson praised their research as truly impressive. Sarah realised that the key to overcoming her anxiety was not to avoid challenges but to face them with curiosity and determination. 1. What made Sarah feel anxious at her new school? A. She had no friends there B. The unfamiliar environment and competitive atmosphere C. Mr. Thompson was too strict with her D. She failed all her exams in the first week 2. What does "kept good company" mean in paragraph 3? A. Worked for a good business company B. Charged David a lot of money C. Provided pleasant companionship during study sessions D. Organised a formal company meeting 3. How did Sarah's attitude change over the project? A. She became more anxious and wanted to quit B. She grew more confident as she worked with a supportive partner C. She lost her curiosity and stopped exploring D. She decided to avoid all future challenges 4. What is the main lesson Sarah learned from the experience? A. Music can always improve learning efficiency B. Group projects are the only way to succeed in high school C. Facing challenges with curiosity and determination helps overcome anxiety D. Having a formal presentation is more important than doing research 【答案与解析】 1. B — 细节理解题。第一段明确指出 Sarah 感到 anxious 的原因是"the unfamiliar campus, the strict teachers, and the competitive atmosphere"，即不熟悉的校园环境和竞争激烈的氛围让她感到焦虑。选项A"没有朋友"虽然与焦虑有关但不是文中直接原因；选项C"老师太严格"只是部分原因；选项D与文中事实不符，文中并未提及她考试不及格。综合判断B最全面准确地概括了原文信息。 2. C — 词义理解题。kept good company 此处意为"提供了愉快的陪伴"，company 取熟词生义"陪伴/同伴"，而非基本义"公司"。文中语境是"在图书馆长时间学习期间David提供了好陪伴"，说明David作为学习伙伴让Sarah感到愉快和有支持感。选项A"为好公司工作"是company的基本义，不符合学习场景；选项B"收费"完全无依据；选项D"组织正式公司会议"与图书馆学习场景无关。这是高考典型的熟词生义考查方式，需要在具体语境中判断词义。 3. B — 推理判断题。第三段写道"Sarah's confidence grew steadily"，且明确说明"having a supportive partner made a significant difference"，表明Sarah在找到支持性伙伴后信心逐步增长。第四段进一步证实她从anxious转变为"overcoming her anxiety"和"face them with curiosity and determination"。选项A"更焦虑想放弃"与原文信心增长相反；选项C"失去好奇心停止探索"与文中"driven by curiosity"矛盾；选项D"决定回避所有挑战"与结尾"not to avoid challenges but to face them"直接冲突。 4. C — 主旨推断题。文章结尾明确写道"the key to overcoming her anxiety was not to avoid challenges but to face them with curiosity and determination"，这是全文核心主旨——面对挑战时用好奇心和决心可以帮助克服焦虑。选项A"音乐总能提高学习效率"是对文中研究话题的过度概括，原文并未得出此结论；选项B"小组项目是高中成功的唯一途径"过于绝对化，文中只是个案；选项D"正式展示比研究更重要"与原文强调的探索过程核心价值相矛盾，原文赞赏的是研究成果本身。 Part 8 复现知识点 — 英译汉 请根据英文写出对应汉语释义： 乐思英语 ·高考高频知识点 1 学科网（北京）股份有限公司 1. anxious — ____________ 2. impress — ____________ 3. concentrate — ____________ 4. confident — ____________ 5. explore — ____________ 6. improve — ____________ 7. curious — ____________ 8. company — ____________ 9. formal — ____________ 10. organise — ____________ 11. anxiety — ____________ 12. impression — ____________ 13. impressive — ____________ 14. concentration — ____________ 15. confidence — ____________ 16. exploration — ____________ 17. improvement — ____________ 18. curiosity — ____________ 19. companionship — ____________ 20. company (熟词生义: 陪伴) — ____________ 【参考答案】 1. 焦虑的；渴望的 2. 使印象深刻 3. 集中注意力 4. 自信的；肯定的 5. 探索；考察 6. 改善；提高 7. 好奇的 8. 公司；陪伴 9. 正式的；正规的 10. 组织；筹备 11. 焦虑；不安 12. 印象 13. 令人印象深刻的 14. 专注；集中 15. 信心；自信 16. 探索 17. 改善；进步 18. 好奇心 19. 陪伴；友谊 20. 陪伴；同伴 Part 9 写作运用 — 词汇升级 用本专题学案词汇替换下列句中的普通词，提升写作表达： 1.
