1.节水常识 中、英文版
1、浴室如何节约用水？ 不要把烟灰、剩饭、废纸等倒进马桶用水冲。
安装一个贮水量小的抽水马桶。这样每冲一次水可节省5-7公斤水。
淋浴器安装节水龙头，选择较短，不用太长水管的淋浴器。 经常检查自来水管的水龙头和水管，看看是否漏水。
即使是漏一小滴水，一个月就白白流掉1500公斤。 2、厨房和洗衣间如何节约用水？ 只有在自动洗碗机里装满要洗的器皿时才使用。
自动洗衣机也是如此。 洗蔬菜时不要一直开大水龙头，而是先在清水槽中洗干净再用水冲洗一遍。
如果不用洗碗机清洗盘、碗，也不应直接用水冲洗。把要洗的食具先放入一个水槽洗净后，再放入另一个水槽快速冲洗。
3、室外如何节约用水？ 只在需要浇水时才给草坪浇水。可以先站到草坪上，如果抬起脚后，草能自然伸直，说明尚不需浇水。
天气凉爽时浇水，清晨为浇水的最佳时间。 把洒水装置直接安装到草坪上，这样洒出的水也可直接浇到草坪上。
种植抗干旱的草或树木，并在树木或植物周围培一层护根的土，以减少水份蒸发。 应该擦洗汽车，而不是用水管冲洗后再擦。
4、家庭节水的主要方法有哪些？ 一是使用水冲厕所的家庭，可在水箱内放置1-2块砖，以减少排水量，达到节水的目的。 二是少用洗衣机，因为用洗衣机洗衣服要比手工洗衣服耗水量多一倍。
为节约用水，除被子、床单等大件用洗衣机洗，其他小件衣服用手工洗为好。 三是采取综合利用、一水多用的办法节水。
如淘米水可用来浇花；洗脸水可用来洗衣或洗脚。 5、家庭节水应注意哪些事项？ 及时关紧正在滴水的水龙头。
在厕所蓄水箱里装一个节水装置。 不要在中午浇花，因为中午阳光强，水易蒸发。
在水龙头上装个流水控制器，可以节约大量用水。 告诉全家成员，在洗蔬果、洗手绢、刮胡子时，不应让水龙头开着。
在你家水龙头处写上“请注意节约用水”。 停电停水后，当你外出时请拧紧水龙头。

6.一篇关于水的作用的英语作文
Water is essential to living things. For instance, if there is no enough water in a human body, a person may feel uncomfortable or get sick easily. To make matters worse, one may die of thirst. Similarly, plants may wither or die for lack of water. It is apparent that all living things need water to keep alive.
Judging from the importance of water, we should know how to conserve water. The first thing is to stop polluting water because what we really need is clean water. At the same time, be sure to turn off the faucet immediately after using water. And we should make efficient use of water to avoid wasting it. One way is to recycle as much water as possible. To sum up, we should economize on water so as to maintain the abundance of water, which is an indispensable element of life.

7.简单的流体学知识,英文版这是一个有关水流为什么在窄的地方流速
speed of water 是水的速度，rate of flow 是流量，水的速度是用m/s来定义的.流量是用m^3/s来定义的.它们之间的关系时 流量=水速*管子的截面积其实你说的是伯努利方程（Bernoulli equation） 流体力学中的物理方程（p/ρg）+(v^2/2g)+h=常量 （p是管子中任何一点的压强，h是管道中任何一点与参考平面的高度，ρ是密度，g是重力加速度）对于一个管子来说，设有A,B两点，那么A,B两点的高度差是确定的，所以（p/ρg）+(v^2/2g)=常量-h等式的右端为一个常量，所以p大的时候，v就减小，p小的时候，v就增大.“窄的地方流速快，宽的地方流速慢”对于这个问题，很好理解，假设管子内有水在流动，设在窄的地方的截面积为S1，宽的地方的截面积为S2，设单位时间内有体积为M的水流入管子，由于水是不可压缩的，所以在窄的地方流速为M/S1，宽的地方为M/S2，显然M/S1>M/S2.。
