常考释义

Nitrates leach from the soil into rivers.
硝酸盐由土壤渗入江河。
Once the humus layer disappears, nutrients cannot be recycled and leach from the soil, converting soil from fertile to infertile and making it suitable only for savanna vegetation.
一旦腐殖质层消失了，营养物质便不能循环并渗入土壤中了，土壤由肥沃变得贫瘠，这就使它只适合热带草原植被的生长了。
来源于：阅读OFFICIAL31 P3Because of rain leaching, most tropical rain forest soils have low to very low mineral nutrient content, in dramatic contrast to mineral-rich grassland soils.
由于雨水浸出，大多数热带雨林土壤的矿物质含量都很低，与富含矿物质的草地土壤形成鲜明对比。

封闭的营养系统发展，以应对热带降雨的严重浸出效应。
来源于：阅读OFFICIAL53 P2The heavy metals are still there, but instead of leaching into the water system and contaminating the water underground, large amounts of these metals may remain bound to the chitin, to the cell walls of filamentous fungi in the soil, and thus remain chemically inactive for as long as 30 years, perhaps longer.
重金属还是在那，但是大量的重金属也许会一直黏着在角素中，黏在土壤里丝状真菌的细胞壁上， 而不是渗透到水系统中污染地下水，因此可以保持化学性稳定30年，甚至更久。
来源于：听力OFFICIAL42 L5Sandy soils are prone to the leaching of nutrients and minerals and so tend to be nutritionally poor.
砂质土壤更易于营养物和矿物质的过滤渗漏，这就导致土壤缺乏营养。
来源于：阅读OFFICIAL31 P3When mineral nutrients do not spend much time in the soil, they cannot be leached into streams.
当矿物质营养素在土壤中消耗的时间不多时，它们不会被浸出进入溪流。
