梯田除了种地，还能怎么帮大山“止血”防水土流失？
Besides farming, how do terraces stop a mountain's bleeding of soil?
一级级田坎像台阶拦住径流，减缓流速、增加下渗，让雨水还没冲走泥土就被田块“接住”了。
Each terrace step slows runoff and boosts infiltration, catching rain before it can wash soil away.

京杭大运河为什么能连通南北、跨越好几个水系？
How could the Grand Canal link north and south across several river systems?
古人用一系列水闸、弯道和补给湖泊，把海河、黄河、淮河、长江、钱塘江串起来，靠逐级调水保持通航水位。
With locks, bends and feeder lakes, it chained the Hai, Yellow, Huai, Yangtze and Qiantang rivers, using staged water control to keep navigable levels.

都江堰的“鱼嘴”是怎么把岷江一分为二的？
How does Dujiangyan's fish mouth split the Min River in two?
江心那道像鱼嘴的石堤把水引向内外两江：外江走洪水、内江进灌区，再靠飞沙堰和宝瓶口调节，自动分水排沙。
Midstream, a fish-mouth-shaped stone levee splits the flow between inner and outer channels - the outer carrying floods, the inner feeding the irrigation district - with the Feishayan spillway and the Baopingkou inlet regulating automatically, apportioning water and discharging sand.

黄土高原的窑洞为什么算一种“古老节能建筑”？
Why is the Loess Plateau cave dwelling an ancient energy-saving building?
它直接利用黄土的隔热保温，冬天不用烧太多煤、夏天不用空调也舒服，几乎不消耗额外能源。
It uses loess's natural insulation, needing little heating in winter or cooling in summer—almost no extra energy.

都江堰修了两千多年，为什么到今天还能用？
The Dujiangyan was built 2,000+ years ago—why does it still work?
它不用大坝硬堵，而是用“鱼嘴”分水、“飞沙堰”排沙、“宝瓶口”控流，顺水势而为，所以历久弥新。
Instead of a dam, it uses a levee to split flow, a spillway to dump silt and a channel to control it—working with the river, so it endures.

新疆的坎儿井为什么要把水渠挖在地下？
Why are Xinjiang's karez channels dug underground?
地面太晒太干，明渠的水会大量蒸发；坎儿井用暗渠把雪山融水引到绿洲，既保水又少蒸发。
The surface is scorching and dry, so open channels lose water to evaporation; underground karez carry meltwater to oases with little loss.
