Passage TwoQuestions 29 to 31 are based on the passage you have just heard.

A. Because the mother supports climate experts’ idea.

B. Because the mother’s habits help reduce carbon emission.

C. Because the mother’s ideas were neglected by their children.

D. Because the mother was influenced by the energy crisis in the 1970s.

题目解答

答案

B. Because the mother’s habits help reduce carbon emission.

解析

本题为细节理解题，考查学生对听力材料中关键信息的捕捉能力。解题核心在于明确问题指向，即“为什么母亲的影响有助于减少碳排放”。需结合选项，锁定材料中描述母亲具体行为习惯的细节，判断其与减少碳排放的直接关联。破题关键是抓住“habits”这一关键词，而非泛泛讨论母亲的观点或外部影响。

选项分析

选项B正确，原因如下：

  1. 材料核心内容：母亲通过日常习惯（如节约用水、减少用电、避免食物浪费等）直接影响家庭成员的行为，这些习惯直接减少碳排放。
  2. 排除干扰项：
    • A错误：材料未提及母亲“支持气候专家的理论”，而是通过实际行动影响他人。
    • C错误：母亲的“被忽视”与减少碳排放无直接逻辑关系。
    • D错误：能源危机是母亲形成习惯的背景，但题目问的是“为什么有效”，而非“为什么形成习惯”。
