Some people think studengts need not do any housework。They think the only thing students need do is to study well。 I don’t think so。 It is good for students to do some housework for three reason。
Firstly,to do some housework can make you independent。You can’t depend on others all your life。So,you should learn to do some housework now。
Secondly, to do some housework can keep you healthy and strong ,some hard housework can be regarded as a kind of physical exercise。
Finally, to do some housework can share your parents’ work 。They must be happy if you say” Have a rest ,and I will do the housework”
So I think it is good for students to do some housework。

水是一切有机体的主要组成部分,全球动植物和40亿人体内含有约11200亿吨水。人类社会依赖水而生存发展。古代,人类对水取利避害,适应水而生存;近代,人类对水兴利除害,兴建工程,开发水利,控制水害;现代,随着社会和生产的发展,地球上可资利用的水日趋短缺,水体受到污染,严重影响人类生存的环境,人类逐渐认识到水是一种重要资源和环境因素,从而在更高的水平上开始对水开展了新的兴利避害活动。
世界气象组织1996年初指出:缺水是全世界城市面临的首要问题,估计到2050年,世界2/3以上的人口将生活在城市,而全球有46%的城市人口缺水,必须平衡社会经济发展和城市淡水供应管理二者之间的关系,进行水资源的储存、输送和管理的大规模工程建设。

你看!邻居的小狗,不也是和我们一样很热吗?只是我们热了会张大嘴巴苦苦哀求妈妈“开冷气”;它呢?只有热得伸出又红又大的舌头,调节自己的体温。
你再看!路上的.行人,不是撑阳伞就是带扇子,一心一意的尽量让自己凉快,可是酷热的太阳却不肯罢休,任凭我们呼天唤地,它还是依然故我,热气蒸人,就连乌云也拿它没办法。
在炎热的夏天里,虽然可以吃冰,但是冰吃多了,对身体不好。虽然也可以开冷气,但是冷气中的“冷媒”,会使大气层里的臭氧层破裂,因此我们还是少吃冰,少开冷气的好,事实上,只要我们记住一句话:“心静自然凉。”烦躁的情绪,就会缓和下来。朋友们,你不妨试试看!
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.
夏天的太阳把大地烤得火热火热,把衣服晒得发烫,把杯子里的水晒没了,把鱼儿晒得直往水里钻,晒得小猫躲得远远的,把知了晒得叫个不停,把人晒得不敢出门,特别是女孩,不涂几层防晒霜出去,准变成“小黑妹”!把柳树的“头发”晒成拖把似的,把小草和树叶晒蔫了。夏天可真热呀!
八月盛夏,晴空万里,天上没有云彩,太阳把地面烤得滚烫滚烫的。不论是在大路上,还是在树木的阴影处,那暑日的炎热总是伴随着你,让人心烦。花儿瘫在地上,好象在洗日光浴;柳叶打着卷儿,湖水上冒着热气,低头看看水中的鱼儿,小鱼该不会被煮熟吧?
每当午后,人们总是特别容易感到疲倦,就像刚睡醒似的,昏昏沉沉不想动弹,连树木里的小鸟,也张着嘴巴趴在树上,懒得再飞出去了。老柳树上的知了也举行了一场合唱比赛,老柳树下躺者一只大黄狗,它伸出红红,长长的舌头,一颤颤的,仿佛在说:“天太热了,天太热了!”坐在大黄狗身后的许多老爷爷老奶奶们,一边拿着扇子散热,一边与人闲谈。
路上的中小学生,穿着校服,有的戴着帽子,有的打着洋伞,似乎都在怨这天气太热。有几个小孩子热得实在受不了,跑到小区里的泳池边,“扑通,扑通”跳进水里。他们像一只只小鸭子,在水里游来游去,相互泼水、嬉戏!
这时,妈妈带我回家了,在路上,我再次往天空望去,心想:这种天气啊,真热,真烦躁啊!今天天气真热呀!火辣辣的太阳吓得风和云都躲得无影无踪。大地被烤得滚烫滚烫的。大树晒得受不了了,你看,原本精神抖擞的树叶,现在已经无精打采。地上花儿那娇嫩的身躯被太阳光烤得垂头丧气的。地上连一只虫子也难寻,原来虫子也受不了这热的煎熬呀!再听听树上的知了,正在不停地叫,好像在说:“真热呀!真热呀!”在树丛里仔细寻找,才找到那些鸟,它们都躲在阴凉处乘凉呢!
此时,走在路上的人们,就像热锅上的蚂蚁一样,来也匆匆,去也匆匆。路边的小狗呢,它热得喘不过气来,它比人们还要热。它穿着一身毛皮大衣,不像人们穿短袖,挺凉快的。它吐出舌头来,发出“哈哈哈”的声音,眼巴巴地看着人们,心里想:要是我能剃掉这身毛,那该有多好啊!
你瞧,那个小男孩已经出来十几次了,难道他一点都不觉得热?不,这不可能,原来他一直去小卖部,到那里去干什么呢?看,他出来了,手里拿着一支冰棒,一袋小冰块,一支雪糕……哎!他也受不了这热的折腾呀!
路上的行人们有的穿着披肩,有的戴着太阳帽,还有的索性打着太阳伞,走在街上。老爷爷、老奶奶都在树下乘凉,都在议论着天的热,都期盼着老天爷再一次降大雨,让空中刮着台风,那是多么令人神往啊!
即使是下雨天,这大街也不会平静。人们打着花花绿绿、各式各样的伞,给大街增添了无限生机。有些小朋友撑着伞,穿着雨鞋,跑到水沟里,把腿伸进水里,使劲一踢,水沟里的水就像大炮一样射向另一个小朋友,他们开心地叫道:“打水仗咯咯······。”有些者撑着伞,慢悠悠地走着,连自己被雨了,眼睛都不眨一下,还有一些行道树贪婪地吮吸着春天的乳汁来一饱自己的'口福。
我喜欢这条街,因为在这能买到自己喜欢的东西。
这条街离幼儿园很近,一直向右拐就到这条街了。我现在一看到幼儿园就想到这条街。
我爱我的家,我的家在幼儿园上面,我出生的卧室,光线很暗,地上很干燥,我很爱它。我的玩具存放地就在左边的房间里,哪儿空气流通散发着阳光的温暖。春天,打开窗户探出头来,往左边看一墙的爬山虎又长了点。秋天,打开窗户一阵风吹来,凉爽极了。
那些美好的印象,我一辈子也不会忘记。
