21. TransForm allows the teens to____________.
- A. select workshops for their parents
- B. prepare track topics for the camp
- C. design programme activities
- D. attend hands-on sessions
答案：D
答案句：TransForm allows you to get to focus on your chosen track through subject matter talks, hands-on workshops, and off-site experiences.
参考译文：TransForm让你通过主题讲座、动手实践工作坊和校外体验来专注于你选择的轨道。
定位线索：题干“TransForm allows the teens to”→答案句“TransForm allows you to...”；文中“hands-on workshops”对应选项D“attend hands-on sessions”。
解析：题干问TransForm允许青少年做什么，答案句直接说明通过“hands-on workshops”（动手实践工作坊）等活动，与选项D“attend hands-on sessions”（参加动手实践环节）同义对应。选项A“select workshops for their parents”在原文中虽提到父母可参加工作坊，但未说青少年为父母选择；选项B“prepare track topics”和选项C“design programme activities”均无原文依据，属于无中生有。
22. According to the schedule, which activity can the teens participate in?
- A. Keynote Speech on 17 July.
- B. Youth Panel on 18 July.
- C. Celebration on 19 July.
- D. Programme Showcase on 20 July.
答案：B
答案句：18 July … 13:00-14:15 Youth Panel … 17 July … 14:00-15:00 Lead to Change Kick-off … 19 July … 15:15-16:45 Adult Workshops … 20 July … 13:30-16:00 Keynote Speech
参考译文：7月18日……13:00-14:15 青年小组讨论……7月17日……14:00-15:00 变革启动会……7月19日……15:15-16:45 成人工作坊……7月20日……13:30-16:00 主题演讲
定位线索：题干“According to the schedule”→答案句取自日程表；文中“18 July ... Youth Panel”对应选项B“Youth Panel on 18 July”。
解析：根据日程表，Youth Panel安排在18日13:00-14:15，与选项B完全一致。选项A“Keynote Speech on 17 July”错误，Keynote Speech在20日；选项C“Celebration on 19 July”错误，Celebration在20日；选项D“Programme Showcase on 20 July”错误，Programme Showcase在17日。这些选项均将活动日期混淆，属于偷换概念。
23. What can the teens do in the Programming Tracks?
- A. Build urban communities.
- B. Serve as guides on a farm.
- C. Learn about healthy living.
- D. Volunteer in a science lab.
答案：C
答案句：·Healthy Living: Empowering you to make healthy decisions in such areas as nutrition and emotional well-being, and lead healthy lifestyles
参考译文：·健康生活：赋予你在营养和情绪健康等领域做出健康决定的能力，并引领健康的生活方式。
定位线索：题干“Programming Tracks”→答案句取自“Programming Tracks”部分；文中“Healthy Living”对应选项C“Learn about healthy living”。
解析：题干问在Programming Tracks中青少年能做什么，答案句直接列出“Healthy Living”轨道，内容为学习健康决策和生活方式，与选项C“Learn about healthy living”直接对应。选项A“Build urban communities”在Agricultural Science中提及“urban farming”但非“build communities”，属于偷换概念；选项B“Serve as guides on a farm”无原文依据；选项D“Volunteer in a science lab”在Science Lab中未提及“volunteer”，属于无中生有。
