表示高度和长度的句子通常遵循以下结构：“基数词 + 单位词 + 形容词”或“基数词 + 单位词 + in + 长度或重量的名词”。例如：

1. The building is 50 meters high.

2. The table is 1 meter long.

3. The path is 200 meters long.

4. We walk up three floors, which is about ten meters high.

5. The well is about 30 meters deep.

这些句子清晰地表达了物体或距离的高度和长度。建议在实际应用中根据具体的语境选择合适的表达方式。
