如何有效利用假期时间英语作文【一】
水是我们生活中必不可少的资源。没有了水，一切都是脏的；没有了水，人的生命将会中止；没有了水，地球上的一切都不复存在。
今天，我跟随着红晚小记者的工作人员走进了农博会的展厅，当走到设施农业站台，看到在桌子上一个奇怪的柱子在不停的伸缩，我立刻就被这奇怪的现象吸引住了。我凑上前去观察这个柱子。我发现：这根柱子在伸出来的时候还喷洒着小水滴，滋润着旁边的植物。它的伸缩及其有规律，每次伸出来还必定伴有小水滴。
经过工作人员细心的讲解，我知道了这根柱子叫喷灌，一个完整的喷灌系统一般由喷头，管网，首部，和水源组成的。
喷灌是借助水泵和管道系统或利用自然水源的落差，把具有一定压力的水喷到空中，散成小水滴或形成弥雾降落到植物上和地面上的灌溉方式。使用这种喷灌方法非常的节约水，因为喷灌可以自由的控制喷水量和均匀性，能保证所有植物都可以吸收到水，喷灌比漫灌节省水量大约在百分之五十左右，省水还意味着节约动力，降低灌水成本。
听完工作人员的讲解我一直在想，如果全国人民都在用这种喷灌系统呢？会有多少节约下来的水呢？如果是这样，多少喝不上水的偏远地区能喝上甘甜，解渴的水呢？我暗暗发誓，以后一定要设计出比这更节约水资源的灌溉系统。让全国人民都过上不缺水的生活。
节约水资源吧，水是我们生活总必不可少的东西，我们也只有一个地球，保护水资源，人人有责。

Time flies like an arrow before we realize it .It is known that nothing is more precious than time. The good old proverb "time is money" reminds us that time is valuable. When time goes by, it will never return. However, it is a pity that some people don't make full use of their time .They spend a lot of time in sleeping, chatting playing computer games or other unmeaning matters. . They don't realize that wasting time is actually equal to killing themselves. They always regret not having made great achievements. One of the reasons may be they do not make good use of time. Therefore, in order to be successful, they should first get into the habit of being on time. It’s a sign of cherishing time. Don't put off what can be done today until tomorrow. Being lazy will eventually lead to failure. Don't wait, because you don't know how long it will take when you put off your plan.
The more we are aware of the significance of this famous saying, the more benefits we will get in study or job.
如何有效利用假期时间英语作文【三】
水是生命的源泉！水的用处可大了，刷牙、洗脸需要水，洗衣、做饭需要水，养花、种树需要水，灌溉农田需要水……总之，水给我们的生活带来了不少的方便。
世界上的淡水资源是有限的。我们乐清就是个缺水的地方，如果长时间不下雨，这里就会干旱，生活用水也难以保证。有一次，我们家停水了。早晨，我拿起水杯，打开水龙头，咦？怎么没水了？我奇怪了。我去问妈妈，才知道停水了。停水了，牙当然不能刷了。我一个上午都没喝水，到了中午，我渴得受不了了，妈妈叫我去买两瓶矿泉水。我带了两块钱下楼，没想到矿泉水要一块五一瓶。我又得回家再拿一块钱下楼，终于买了两瓶矿泉水回家，唉，可真麻烦！
尽管这样，有些人却不珍惜水。在学校里，我就看见有些同学浪费水。有一天，我来到盥洗室里接水，只见一个同学拿着一个瓶子，瓶盖上有一个小洞眼。他接了满满一瓶水，捏住塑料瓶往别人身上射水，我们制止他，他却不听。这样，他一直玩到上课才回到教室。看到这种浪费水的现象，我真气愤。
水是万物之源。如果没有了水，土地会干裂；如果没有了水，花、草、树木将会枯萎；如果没有了水，人类将会渴；如果没有了水，就看不到这个美丽可爱的世界。
水看似很普通，但万物都离不开水。假如世界上的水用完了，那我们的眼泪将会成为人们争夺的最后一滴水。保护水资源，是每一个地球公民的责任。
