n. 水文循环
1. The hydrologic cycle(Figure 1.1),also known as the water
cycle or H2O cycle,describes the continuous movement of water on,above and below the n. surface of the earth.Water 水汽 can change states among liquid,vapour,and solid at various places in the water cycle.
2.2 Important sentences
（第三段）3. The sun,which drives the wateFra Baidu bibliotek cycle,heats
water in oceans and seas. Water evaporates as water vapour into the air.Ice and snow can sublimate directly into water vapor.Evapotranspiration is water transpired from plants and evaporated from the soil.Rising air currents take the vapor up into the atmospere where cooler temperatures cause it to condese into clouds.

2.2 Important sentences
（第三段）5. Not all runoff flows into rivers,much of it soaks
into the ground as infiltration.Some water infiltrates deep into the ground and replenishes aquifers,which store freshwater for long periods of time.Some infiltration stays close to the land surface and can seep back into surface-water bodies(and the ocean)as groundwater discharge.Some groundwater finds openings in the land surface and comes out as freashwater springs.Over time,the water returns to the ocean,where our water cycle started.

译：并不是所有地表径流都流向河流，很多渗入地下形成渗滤。部分水渗透到地 下深处补充能长时间储存淡水的地下蓄水层。一些地表附近的渗透可以以地下水 排放渗出到地表水体（海洋）中。可以在地表发现泉水口等一些地下水的出口。
随着时间的推移，水会回到水循环开始的地方—海洋。

（第三段）4. Air currents move water vapor around the
globe,cloud particles collide,grow,and fall out of the sky as precipitation.Some precipitation falls as snow or hail,sleet,and can accumulate as ice caps and glaciers,which can store frozen water for thousands of years.Most water falls back into the oceans or onto land as rain,where the water flows over the ground as surface runoff.
译：太阳可以通过加热海洋中的水来推动水循环。水蒸发成水蒸气进入空气中。 冰和雪能直接升华成水蒸气。土壤水分蒸发蒸腾损失包括植物蒸腾和土壤水蒸发。 上升气流将水汽带入大气中，使其受低温影响冷凝成云。
New Words & Expressions:
oceans and seas n. 洋和海 sublimate v. 升华 Evapotranspiration n.土壤水分蒸发蒸腾损失
译：气流将水汽带到世界各地，云团会碰撞聚集扩大，最后会从空中沉降掉落。 雪，冰雹，雨夹雪等的降落，可以积累成能冷冻水数千年的冰帽和冰川。大部分 的水以雨的形式回到海洋，和存在地表径流的土地上。
New Words & Expressions:
Collide vi. 碰撞，冲突 precipitation n.沉淀;（雨等）降落 glaciers n.冰河，冰川
境中吸收能量使其冷却。相反，在冷凝过程中，水通过对周围释放热能使环境温 度升高。
译：水循环包括能导致温度变化的热能交换。例如，在蒸发过程中，水从周围环

2.2 Important sentences
2.
The water cycle involves the exchange of heat energy,which leads to temperature changes.For instance,in the process of evaporation,water takes up energy from the surroundings and cools the environment.Conversely,in the process of condensation,water releases energy to its surroundings,warming the environment.
