as we know , water is very important to man, we can’t live without water. the amount of water which is suitable to drink is less and less. but some people don’t care about it .they waste a lot of water in their daily life. even worse, they pour dirty water in to rivers. they throw rubbish into rivers , too. many rivers and lakes are seriously polluted.something must be done to stop the pollution. only in this way can we live happily. if we don’t save water, the last drop of water will be a tear-drop of us.
we know that despite the fact that seventy percent of the earth's surface is covered with water, only a little part of it is fresh water. yet the demand for fresh water in our daily life and in industry seems great. moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even rapidly. it is estimated that if such a trend continues, the fresh water on earth will be exhausted very soon. what is worse, more and more water resources are being polluted, making the water unfit to use.
in addition,we must warn the people of the importance of water and the danger we are facing.for example, in most asian societies where rice is the staple food, the water used after cleaning rice contains various nutrients for plant growth and is an excellent detergent to flush the toilet. furthermore, the intriguing idea of converting the inexhaustible sea water to fresh water supplies will be the ultimate solution.
在我十岁生日的时候,妈妈让我吹灭一个个燃烧中的蜡烛,我闭上眼睛许愿,妈妈就在我许愿时拿出一个盒子,上面有几个圆形的小洞,让我猜里面是什么,妈妈看我疑惑不解的样子,慢慢地打开了盒子。啊,里面是一只白色的小狗,毛绒绒的好可爱,这可是我一直梦想能得到的,我把它抱在怀里,心里那个美呀!
它成了我的朋友,妈妈不在的时候,他是我忠实的玩伴。天空中不知不觉下起了白色的雪花,和我的孤独一起堆积在我心底。而我的宠物狗好像明白了我的心思,让我和它一起玩耍,在陪它玩的过程中,它一点一点、一层一层的剥开我心中的积雪,一片一片的点燃喜悦的烟花。我带它去公园玩,它那一身的白色和天空中的雪花相照应。它在前面跑,我在后面追,是它带我去了一个不再让我忧伤的世界,在那个世界里云朵是糖果状的,还时不时的有流星划过,我们坐在云朵上玩耍,它那几声可爱的叫把我们又带回现实生活中。春天的时候,我们在嫩草上玩耍,我们坐在草地上,它还时不时的钻进我的怀里,和我撒娇。玩了一天了,好累啊!来我们一起洗澡吧!我为它洗澡,它很听话,坐在盆里一动不动的,像个雕像一样。我把它抱到它的小床上,它便呼呼大睡起来早上还知道我起不来床,所以用它那光滑的舌头舔我,叫我起床。夏天我带它出去的时候,它还老是和邻居家的小花狗玩耍,追着人家跑。一两岁的小弟弟看到了它,用手轻轻的去摸它,便马上笑了起来。它总是跟在我身后,去商场买东西也要带上它。秋天的时候,树叶落到了它的头上,它便要撒了欢的跑起来。
如今,我是一个中学生了,学习的科数增加了,时间受到了限制,不能再像以前一样带着它去玩了,它好像读懂了我的心思,不像以前一样撒娇,而是只坐在一边看着我学习。它是我的宠物,但也是我的朋友,无论什么时候它总是在我身边,陪伴我学习和生活。

水的重要性(一)
the importance of water(一)
it is well-known that water is indispensable in existing, in producing and in living. and we should
not waste of a drop of water.
众所周知,在生产和生活中水是必不可少的。我们不应该浪费一滴水。
first, water is definitely important for life. as is known to us all, water is necessary to sup
port life. without water, human beings, animals and plants cannot exist at all.
首先,水对生命是非常重要的。众所周知,水是维持生命所必需的。没有水,人类,动物和植物都不复存在。 second, water is also significant for producing. for one thing, industrial production needs a lot of water, such as using water to generate electricity. for another, agricultural production is also in need of water, especially in irrigation.
现在十分流行爬宠,所以我家也养了一只小乌龟。它全身除了背甲外都是黑色的,脑袋尖尖的,四条腿很粗壮,可能是吃得太多了吧。脖子上有独一无二的花纹,就像指纹一样。最漂亮的就是它的背壳了。背壳呈椭圆形,中间几块甲是有些偏黑的灰色,外面围了一圈黑色的鳞甲,就像一块名贵的猫眼石,所以我叫它“宝贝”。
虽然小宝贝很可爱,但他是冷血动物。养它的最大乐趣,那就是长大了。今年冬眠过后,细心的妈妈发现小宝贝的甲片之间有了白色的生长纹,这说明它又要长大了,妈妈高兴得又跳又笑,急忙兴冲冲地网购了龟粮,还买了一个更大的盆子来养它。在妈妈的不懈努力下,小乌龟整整长大了一圈,背上的甲片也增加了好几片。妈妈开心极了。我心里也痒痒的。想帮助小乌龟的那一天。
一天,妈妈又来给小乌龟喂食,却发现它一点都没动,就走开了。过了一天,妈妈又过来看了看,小宝贝还是“只出不进”,妈妈急得焦头烂额。我一看,心中一惊,不会像书上说的那样得了“抑郁症”了吧?急忙在客厅中划了一块约3平方米的区域,里面放上网购到的“小乌龟游乐设施”,再拿几本大部头的书围起来,在一个角落里放了一些小鱼干,这样就不怕它饿肚子了。
有一次,我们一家要出远门。我就把小乌龟放在游乐场里,并在书籍和地板上铺了一层防水的保鲜膜,再把食盆调离地面3厘米,并放上10粒龟粮和10条小鱼干,最后再注上水,小龟的水中乐园就大功告成了。我们放心地走了。10天后,我们回来了,一看,只见游乐场里半个小乌龟的影子都没有,食盆里空空如也。我赶紧找了起来:沙发下、客厅里、卧室里……都找了,就是找不到它的踪影,我正准备放弃时,耳朵忽然捕捉到从厨房传来的声音,去那一看,小宝贝就在那里,还在扒拉装咸鱼的袋子呢!
这就是我家那聪明可爱的小宝贝——小乌龟。
