参考答案与解析

答案: 地点。

表达迁移: 根据下面给出的原创文字情境,改写三句观察:小涟漪在浅盘中向四周扩散;到达盘边时,可见的波纹形态发生变化;这些描述只适用于这个模型。用 where 从句说明变化发生的位置,并在末句保留模型范围的限制,不补写文字中未给出的速度、高度或原因。

表达参考与点评

Small ripples spread across the tray. Where they meet the edge, the visible pattern changes. This observation describes our model and does not cover every kind of wave.

第一句改写文字情境中的扩散,第二句用 where 从句指出盘边这一变化位置,第三句保留模型边界。任务只依据本页文字,不要求实际演示或图示,也不把给定情境当作所有水波的普遍规律。
