What does it actually claim? 4. Which card is the strongest evidence about this school decision, and why? Give TWO reasons. 5. Is Card C necessarily a lie? Does it prove the school has made a decision? Explain the difference. 6. Write a 25–35-word reply to the forwarded message.

B应标出the computer room、from 1 to 5 November及Classroom computers will work as usual。C可圈I find和I think等。 3. 核查记录参考 Check Card A Card B Card C Author Not given School IT office A parent Evidence Hearsay only; no original notice A dated notice with scope and a contact office Personal experience and opinion Claim No computers anywhere in school Computer room closed 1–5 November; classroom computers continue The parent thinks the school should remove computers 4. Card B。在这个模拟材料中,它来自负责相关事务的部门,有明确日期、场所、期限和联系渠道;A只有转述,C不是学校决定的证据。来源权威不意味着现实中永远不会出错,关键仍是核对原文与适用范围。 5. Not necessarily. Card C expresses a personal preference and suggestion. It does not prove that the school has made that decision. 个人意见、虚假信息和已经核实的事实不是同一回事。 6. 示例,共30词:According to the school IT office, only the computer room will close from 1 to 5 November for repairs. Classroom computers will work as usual. Please check the original notice. 7. a. Eight. b. 4/8 = 1/2,即50%。c. No. The sample is small, and the question is about yesterday’s main activity, not everyone’s preference. 只指出样本小亦可;能同时发现“行为不等于偏好”应给予肯定。 U3 跨学科探究课 参考答案 2 Think before you click and share 短帖示例与评价 8. 示例,共45词 Eight students online We asked eight students about their main online activity yesterday. Four chose learning, two chose chatting, one chose games and one chose reading news. These practice data describe only this small group on one day. They do not show what all students usually do online. 9. B更有用。它回应观点、交代数据范围并邀请提供证据,没有攻击个人。自拟例:People enjoy different activities. Our small survey only describes yesterday, so we need more evidence before making a wider claim. 10. 可选三项:check the author/source;check the date;check the evidence;read the whole message;compare it with the original notice;check the scope;use kind language。选项合理且可执行即可。 第8—9题综合评价共8分 观察点 达成表现 分值 数据准确 人数及活动对应正确,无夸大 2 范围清楚 说明八人、昨天,并指出局限 2 表达清楚 短帖有信息,英文可理解 2 交流得体 回应观点,礼貌且能寻求证据 2 挑战作业核对:横轴四类活动,纵轴人数;柱高依次为4、2、1、1;纵轴从0开始,建议刻度0—4。图题应说明是八名学生昨日主要网络活动的练习数据。 课堂组织:信息核查、计算和短帖均可个人完成;评论回应只需同桌交换一次。学生无需账号、手机或联网条件。 材料说明:三个探究维度取自教材第48页Digital literacy。学校通知、转发信息、评论及调查数据均为专门编写的课堂模拟材料,不对应真实学校政策或调查结果。 第 页 学科网(北京)股份有限公司 $
