目前,关于人口构成变化的可能影响,主观臆测要多过可靠结论。但这种情形应该会引起广泛的比较研究,而且这种研究可能会对欧洲和中国的政策制定具有非常重要的借鉴意义。

人口普查是当今世界搜集人口资料的一种最基本的科学方法,世界各国都异常重视,但基于国情的不同,各国的人口普查又各有特点。

世界人口结构中,欧洲将持续边缘化

人口构成的这些变化将给政治革新和社会研究带来更大的挑战。

人口构成变化的可能影响,目前还是臆测为主

人口构成变化还将产生其他影响。从农村向城市的地理性移民将会同时向高速发展的城市和遭遇净人口损失的农村提出挑战。比如男女比例失调,在中国,男女新生儿比例为117:100,农村地区这个比例更为悬殊。家庭模式也可能产生变化,比如婚龄推迟、离婚率上升等等,所谓的“第二次人口构成变化”也可能加剧(“第二次人口构成变化”是指同居、单亲家庭、非婚生育以及低生育率等现象大幅度增多,以及更多人不愿结婚和接受约束性行为的传统规范的现象)。

挪威社会学家、联合国教科文组织国际社会科学委员会主席古德蒙·赫内斯认为,目前,关于人口构成变化的可能影响,主观臆测要多过可靠结论。但这种情形应该会引起广泛的比较研究,而且这种研究可能会对欧洲和中国的政策制定具有非常重要的借鉴意义。

世界人口普查

俄罗斯 根据俄罗斯联邦《居民人口普查法》,俄罗斯每十年至少应该举行一次人口普查。人口普查的时间精确到时,即年、月、日、时。20xx年的人口普查是苏联解体后俄罗斯进行的首次人口普查,对于国家掌握居民情况和制定社会发展计划发挥了重要作用。那次人口普查使政府获得了关于人口数量、年龄、性别、婚姻状况、民族成分、受教育程度、家庭副业、就业与收入、住宅状况等资料,既有联邦范围的,也有地区的。最重要的是获得了社会民族结构方面的信息。政府根据这些信息及时调整了国家和地区的社会发展规划。

It is a fact that college is becoming more and more expensive and college life is becoming especially hard for the students who were born in needy families. However, there are several ways in which these students can cover their tuition that their parents are not able to afford. Finding a part-time job, for example, is an ideal way. Besides, one can ask the bank for a loan and repay it when he has the ability. Finally, one can seek assistance from the society.

For me, earning tuition by doing part-time jobs is the most suitable way. First, I learn to be independent both mentally and economically in this way. Apart from this, I no longer need to wor-ry my parents with so heavy a burden. Finally, since I earn my own living, I will be more confi-dent with myself and, therefore, I can live a busy but meaningful college life.

presently, the world is faced with serious water problems. but these problems witt become more intense and more comple in the future. our increasing population witt tremendously increase urban waters, primarily sewage. on the other hand, increasing demands for water witt decrease substantially the amount of water available for diluting wastes.

rapidly epanding industries which involve more and more comple chemical processes will produce large volumes of liquid wastes. many of thesewitt contain chemicals that are poisonous. to feed our rapidly epanding population, agriculture will have to be intensified.

this will involve ever increasing quantities of agriculture chemicals. from this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problems.

there are two ways by which these pollution problems can be lessened. the first relates to the treatment of wastes to decrease their pollution hazard. this involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes to permit the reuse to the water or best reduce pollution upon final disposal.

the second approach is to develop an economic use for all or part of the wastes. farm manure is spread in fields as a nutrient. wastes from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained.

liquid wastes from other processing plants may also be used as a supplemental source of water. only by doing these promptly now can we epect to solve the serious water problems in the future.

The human race has experienced a consistent increase in population since the beginning of its history. Famine and disease have done little to offset this steady increase. Too many people are added annually to the population of the world. So both the causes of population increase and the results of having more people are worth careful study.

Culture evolution is the major factor responsible for population increase. Early in human development, people invented tools to hunt animals. Later they built shelters to protect themselves. Step by step, they made life easier. As a result, fewer died from natural forces, such as harsh climate and disease.

In the past, when population grew, there was unexplored territory to inhabit. But now, almost all the habitable land has been explored.From joozone.com.

The worlds population may reach 8.7 billion in 2033. It is clear that world population is a serious issue that needs careful attention. Human beings are unique to solve problems through cultural evolution.Facing the world population explosion in the near future. We must carry out the birth control program in order to save the mankind and save the world.

Nowadays,with the rapid increase of population,the problems of overloading in cities is becoming more and more serious around the world.

In order to deal with the problems caused by overloading,in my opinion,Lowering the birth rate is the essential methods.On the other hand,another way which is executable to reduce the pressure of population in cities is to move people from cities to suburban areas.Of course,this need the help of governments.

2004 marks the 10th anniversary of the groundbreaking International Conference on Population and Development (ICPD) in Cairo, Egypt, in 1994.

Ten years ago, on the eve of World Population Day, a new campaign was launched to raise awareness of how international family planning helps save women and childrens lives, safeguard the environment, and slow population growth. 179 governments committed to it when they signed the Program of Action of ICPD, which prescribes the steps that will not only save millions of womens lives but empower(授权, 使能够)societies to achieve a better future.

Today, there are more than 6 billion people on the planet, with half of the worlds population under the age of 25-at or just reaching their childbearing(分娩)years.

Nearly 600,000 women still die each year from pregnancy-related causes. And an estimated 90 percent of infants whose mothers die at childbirth will not survive to their first birthday.

Wild species are becoming extinct 50 to 100 times faster than they naturally would, because of the impact of rapid population growth and increased population density in many countries.

Though population growth is slowing worldwide, more than 90 percent of current growth occurs in the developing world where needs are great and resources are scarce. And these nations have a huge unmet need for family planning services-over 150 million married women of reproductive age in the developing world indicate that they would prefer to postpone childbearing but are not using any method of contraception.

"Girl born today in the developing world faces better prospects than a girl who was born 10 years ago. School enrolment rates are increasing, mortality is declining and life expectancy(平均寿命) is rising, more and more women and couples are able to choose the number and spacing of their children and many countries are taking additional steps to confront HIV/AIDS. But progress is uneven, and in some cases slipping backwards. We need the strength and determination of a marathon(马拉松赛跑)runner to meet our goals during the next decade."

Population officials and demographers have much to worry about China’s increasingly aging population. It is estimated that the proportion of people aged 60 or older in China will rise to 11.8 percent in 2020. By the middle of this century, people aged beyond 60 will take up 27.4 percent of the total population — that means one out of every four people will be senior!

The aging population poses a serious challenge to families and the society. On the one hand, with families becoming smaller and living pace escalating, it is even graver for families to care for aged members adequately. On the other hand, aging causes a relative decline in working force. Consequently, the productivity of the whole society will be affected to some extent.

The rapidity of the population’s aging has made it more urgent for the adoption of countermeasures. There is no doubt that the key is to build a solid economic foundation. Meanwhile, importance should be attached to overall social progress by changing the backward situation in social security, welfare and service.

自改革开放之后,中国民众从小规模的地下方式开始自主进行人口流动。这股潮流越发猛烈,以至于政府在十几年之后不得不彻底取消了大部分对人口流动的严格限制。行政的控制无法阻挡经济利益的诱惑。因为多年控制的压抑,这一系列人口流动最终爆发成为了人类史上空前规模的迁移。中国的城市与乡村在建立社会主义制度之后完全隔绝了如此之久,以至于中国社会的城乡二元结构时至今日仍影响至深。城市是人类文明对自然环境改造的终极形式,是人类工商业活动的最集中场所。人口不断从乡村向城市迁移,而不同等级和发展水平的城市之间也存在着大量人口流动。大城市的梦想造就了数量庞大的流动人口。而这些流动人口的进入也使得城市变得更大更密更复杂。城市的活力在几十年的隔绝制度下已渐衰弱,而流动人口改变了这一切。城市被注入新的生机,重新成为经济活动的中心、文化碰撞融合的焦点,从而被丰富和多元化。中国的城市化水平在短时间内迅速提高,但更重要的是多数城市的生命被延续,并因此有助于打破几十年养成的城乡二元思维。

而所有被称为流动人口带来的不良后果,在我看来都是对城市管理不作为而找出的借口。这样的借口所编织的谎言是几十年来权威主义管理的惯性。所谓流动人口所带来的问题是普世的,即无论在哪个被界定的人群中,人类现有的文明也保证在相同条件下都可能会发生相同的或好或坏的事情。而那些谎言是最擅长“以偏概全”的。甚至有时候还会牵扯出流动人口的素质问题。这简直是无耻的。这是教育资源分配不均的问题,是教育机会不平等的问题。难道这是流动人口自身造成的?流动人口给城市带来的居住、交通、医疗、教育等等压力,再一次提醒了城市管理者如何才能合理分配城市资源。在城市中辛勤工作、依法纳税、遵纪守法的公民完全有资格公平而合理地利用到城市社会资源,而不会因为什么户籍问题沦为二等公民。讨论所谓流动人口所带来的弊端显然是带有偏见的,而如此的利弊二元思维也是极其可悲的。要知道,这个世界本是没有城市的。

近些年,教育出现了不少新情况,其中之一是在一些城市中,出现了各种各样的“打工者子弟学校”,专门流动人口子女就学。对于此显现,各方面的意见很不一致。一方面,在各大城市中打工的流动人口表现明显的欢迎。其原因在于:他们认为,上不起城市的公立中小学。公立学校如果接受外来人口的子女上学,在正常的学杂费之外,一般要收较高的借读费和赞助费。另外,他们认为自己的子女在公立学校上学还会受到城市孩子的歧视。而“打工者子弟学校”一方面收费比较低,而且服务也很热情,孩子也不会受到城市小孩的歧视。

关于办学条件问题,很多人认为应当考虑具体情况,相当于公立学校,这些“打工者子弟学校”的教学条件肯定比较差。然而,根据这些学生的家庭的收入水平和支付能力,我们是否一定要去那么高标准教学条件呢?如果政府不能负担这些孩子教育的费用,我们能看着它们失学吗?我们是否要拥有者的教学条件作为学生入校的门槛呢?只要能改这些孩子一个受教育的机会,条件简陋的学校应当是可以生存的。实际上,流动人口将子女送到这类学校主要是经济上的考虑,这类学校收费较低相当于贫民学校,使这些家庭的经济条件。

在我们班就有一位流动人口儿童,他跟着父母一起来到到这里。。起初,他在班上不怎么说话,上课只是认真听讲也不发言……过了一段日子,有几位同学“邀请他去玩,于是他露出了在校园里的第一张笑脸,随后他经过和老师同学的沟通慢慢变得开朗起来,学习也十分优异,现在成了我们班的尖子生。

如果给流动儿童一个学习的机会,一个沟通的机会,他们就会和别人平等。

From these graphs, we can draw a conclusion that, with the growth of human population, the number of species has decreased rapidly in America, and some species have even vanished from our planet.

Why does this phenomenon appear? There are several possible reasons for this. Above all, as the human population grows rapidly, a growing number of people came to live where some wild species have been living. Then these species have to move to other places. Some of them probably can not adapt to the new environment and die. In addition, although many people look on the wildlife as their friends, some people may not think so. They catch a lot of wild animals and sell them in order to get more money. Even worse/More importantly, as the result /consequence of the industry, the natural balance and the ecologic environment are destroyed. The clear cutting has become increasingly serious. So some of the wildlife become homeless and extinct.

In order to protect the wildlife, I have some suggestions. First, the governments should make laws to prevent them from being caught and killed. Second, the governments should educate people to love nature and protect it. Third, as for ourselves, we should take practical actions to protect our living environment.

导语:如今,盗版问题变得越来越严重。书籍,磁带,光盘和其他高科技产品已盗版。下面是yuwenmi小编为大家整理的相关英语作文,欢迎阅读与借鉴,谢谢!

Nowadays,the problem of piracy has become more and more serious. Books,tapes,VCDs and others high-tech products have been pirated. For instance,when a new product comes onto market,most probably,its pirated counterpart will soon put on its appearance in the market,too. Piracy has caused a great loss to legitimate producers,inventors and writers in many ways. To start with,the pirated products often cost much less than the genuine ones so that they enjoy a better trading position in spite of their relatively poor quality. The genuine products,on the contrary,sell poorly. Whats worse,pirated books sometimes do great harm to the authorsreputation due to some misprints. In the long run,pirated products may have a negative impact on customers. Those legitimate producerscreativity and enthusiasm may be deeply hurt by the fact that some customers are more interested in the pirated products for the sake of small gains. In my opinion,its high time that everyone started the battle against piracy.First,customers should develop their consciousness to resist the pirated products. Second,the government should take effective measures to put an end to piracy. Finally,laws must be strictly enforced to completely ban piracy. Only in this way can we wipe the pirated products out of our life.

【参考翻译】

如今,盗版问题变得越来越严重。书籍,磁带,光盘和其他高科技产品已盗版。例如,当一个新产品出现在市场上,最有可能的是,它的盗版产品很快就会出现在市场上。盗版行为在许多方面给合法的生产者、发明家和作家造成了巨大的损失。首先,盗版产品通常要比那些正版的要低得多,以至于他们在质量相对较低的情况下享有较好的交易地位。相反,真正的产品卖不好。更糟糕的是,盗版书有时危害巨大,由于一些作者错误的观点。从长远来看,盗版产品可能会对客户产生负面影响。那些合法的生产者的热情,也许是因为有些客户是在盗版产品为了少的收益更感兴趣,深深的伤害了。在我看来,每个人都开始了打击盗版的斗争,第一,客户应该发展他们的意识,抵制盗版产品。其次,政府应采取有效措施,结束盗版。最后,法律必须严格执行,完全禁止盗版。只有这样,我们才能把盗版产品从我们的生活中抹去。

篇19:说明文:中国人口问题

中国人口问题和环境问题几乎是同时被人们重视起来的。人们将中国人口数量过多作为环境恶化的根本原因,将人口与环境对立起来,使很多人认为,要想从根本上解决中国的环境问题,就应该努力地削减中国的人口。但是,我们可以举个简单的例子:中国的森林面积在逐年减少,沙漠面积在逐年扩大,空气和水体质量越来越差,如果我们单纯地与俄罗斯、加拿大、美国、澳大利亚等国家相比,是很容易得出“人口少则环境好”这样的结论的。然而如果我们与日本、新加坡这些国家相比,就只能承认我们在环保意识和环保工作方面的差距。所以,我们可以说人口数量不是根本问题!

要创造和谐的人口与环境,我认为提高人口素质是减缓环境恶化的关键。它一方面受遗传因素的影响。比如“母强儿壮”反映了先天因素对人口身体素质有重要影响。再如白化病等很多疾病都属于遗传病,两个携带致病基因的人结合很有可能给下一代造成不幸。所以社会提倡优生优育,禁止近亲结婚。另一方面受社会和自然因素的影响。比如我国封建社会妇女裹足对人身健康的摧残;古巴比伦王国由于社会伦理道德的败坏导致文明的衰落等等。人类社会发展到今天,人口身体素质的高低,越来越取决于社会环境因素。人们对身体素质的要求越来越高,到处可见人们晨练的身影,并且平时的问候语也经常听到:“身体好吗?”这样的话,人们不再追求吃饱,而是讲究吃得健康,“有健康才有将来”已经逐渐成为人们生活的信条;比如电信业的发展具有的微波辐射污染,现在家庭电脑普及,手机泛滥,电器设备应有尽有;交通业建筑业等噪音污染,特别是日益发达的交通事业,汽车成为代步工具,虽然加快了生活节奏,但也加速了尾气的排放,加大了环境污染;日益发展的工业企业排放的有毒物质,严重影响了土壤、森林、气候,破坏了生态平衡。导致很多地方出现泥石流,山体滑坡现象。以上这些引起的环境问题都会通过空气、呼吸携带传染物,传染到人体,给人造成致命的伤害。这些自然环境对人口身体素质的影响也都是决定性的。

所以,人口与环境的问题不是决定与被决定的关系,而是相互统一的关系。提高全民的人口素质,会使我们的环境更加的美化;同样创造更加美好的社会和自然环境会让人口素质迅速提升,只有这样,我们的社会才更加和谐,更加美丽!
