医疗卫生事业的发展使得人口出生率和成活率迅速提高,死亡率大幅度下降,引起全球人口急剧增长。
世界人口递增的时间越来越短。工业革命时期1800年到1839年,世界人口由10亿增加到20亿,到1960年为30亿,1975年为40亿,1987年7月为50亿。发展中国家占世界人口比重由50年代的66,8%上升到80年代的74,9%。至20xx年全球人口增加到61亿,其中85%的增加大多集中在亚洲、非洲和拉丁美洲。
而在未来的30年中,人口增加率将会减缓,到20xx年时,世界人口的总数将为80亿。人口增长率将达到历史性的低点。
从文化教育程度看,目前,全球有9,6亿文盲,其中1,3亿儿童。发达国家许多成绩优秀的高中毕业生不愿选择理工等相对艰苦的专业,使得在培养艰苦岗位上所需合格人才陷于困境。发展中国家无力培养更多的人才,而人才从发展中国家向发达国家的流失更加剧了发展中国家的人才危机。以印度为例,到1990年为止,在外谋生的科学家和熟练技术人员达41万,到20xx年达54万。
从健康的.角度看人口素质,许多疑难病、奇特病的增加表明人口素质的下降。如艾滋病、变异链球菌、奥罗凯病毒、登革热病毒、非典病毒等,正以惊人的速度吞噬人类的生命。
发达国家的人口问题:人口总规模萎缩,人口老龄化。1991年,瑞典老人比重18%,英国16%,日本12%。造成的问题:①社会经济负担加重②劳动力老龄化③生产率低④社会问题多。
发展中国家的人口问题:农业人口多,出生率高,“越穷越生,越生越穷”恶性循环。引发的社会问题是,①贫穷与饥饿②失业③奇型城市化,其后果是失业加剧,人口分布奇型,出现大量工棚区。
Bicycle is a convinient means of transporation. It has been very popular in China. During the rush hours, particularly in big cities, you can often see a sea of bicycle riders in the streets. People can ride bicycles to their working places, to schools, to shopping centers and so on. In a word, bicycles play an important role in daily life.
Compared with cars, bicycles have many advantages. Firstly, they are not so expensive as cars and almost every family can afford to buy and repair them. Secondly, riding bicycle is a healthy form of exercise. They do good to our health. Thirdly, bicycles can save energy and does not cause any pollution, while cars will cause serious air pollution, which makes the air in our living place very dirty and makes a lot of people suffer from lung cancer. As we all know, China is a country with a large population. Ifeach family has a car, a large amount of energy would be wasted and air pollution would become more and more serious. Finally, most Chinese people don’ t live far away from where they work or study, it is convenient to ride bicycles. I think that is why bicycles are used so much.
Bicycles are so popular in China that China is often referred to as the kingdom of bicycles. I hope more and more people can ride bicycles in order to make our planet better and cleaner.
自行车是一种方便的交通工具。它在中国非常受欢迎。在高峰期间,尤其是在大城市,你可以经常在街上看到自行车骑手。人们可以骑自行车上班,学校、购物中心等等。总之,自行车在日常生活中起着重要的作用。
与汽车相比,自行车有许多优点。首先,他们不是很昂贵的汽车,几乎家家都能买得起和修理它们。其次,骑自行车是一种健康的运动。他们对我们的健康有益。第三,自行车可以节约能源,不会造成任何污染,而汽车会造成严重的空气污染,使我们生活的地方的空气变得非常脏,使很多人患有肺癌。我们都知道,中国是一个人口众多的国家。如果每个家庭都有一辆汽车,就会浪费掉大量的能源,而且空气污染会越来越严重。最后,大多数中国人不远离他们工作或学习生活,骑自行车很方便。我认为这就是自行车在中国大量使用的原因。
自行车在中国如此受欢迎,中国通常被称为自行车王国。我希望越来越多的`人可以骑自行车为了让我们的地球更好的和更清洁的。
