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.
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。
但是也有部分学者多该文的真伪提出了质疑,因为该地人口主要为日耳曼人,大部分该地人还在使用德语,电视和报纸也以德语为主,不可能出现这样的状况。法国反而对该地居民实行严厉的种族同化政策,致使该地人民对法国人恨之入骨。所以,纳粹德国占领法国后,积极招募阿尔萨斯人加入军队。法国城镇加拉尼大屠***的实施者就是以阿尔萨斯和洛林人为主的党卫军第二师。电影《老枪》就反映了这段历史的一个局部。
这也从一个侧面反映了阿尔萨斯人和法国的关系。该地在战后一直积极寻求自治,最终迫使法国政府终止了这一行径。1871年后新的法德边界基本是按照语言分布的界线走的,只有在洛林西部,德国出于军事方面的考虑吞并了法语人口占多数的梅斯(Metz),这座城市是法国东北部的交通枢纽,而且有规模巨大的设防要塞。另一方面,贝尔福地区虽然在传统上属于阿尔萨斯,行政上也属于割让给德国的上莱茵省,但其人口中法语居民占绝大多数,因此德国并未吞并该地。
