Australia:An introduction
In land area,Australia is the sixth largest nation after Russia,Canada,China,the United States of America and Brazil.It has,however,a relatively small population.
Australia is the only nation to govern an entire continent and its outlying islands.The mainland is the largest island and the smallest,flattest continent on Earth.It lies between 10掳 and 39掳 South latitude.
The highest point on the mainland,Mount Kosciuszko,is only 2228 metres.Apart from Antarctica,Australia is the driest continent.
Australia is the driest inhabited continent on earth.Its interior has one of the lowest rainfalls in the world and about three-quarters of the land is arid or semi-arid.Its fertile areas are well-watered,however,and these are used very effectively to help feed the world.Sheep and cattle graze in dry country,but care must be taken with the soil.Some grazing land became desert when the long cycles that influence rainfall in Australia turned to drought.
The Australian federation consists of six States and two Territories.Most inland borders follow lines of longitude and latitude.The largest State,Western Australia,is about the same size as Western Europe.
Natural environment
Australia has a remarkable diversity of life forms seen nowhere else in the world.Australian plants and animals evolved in isolation from other parts of the world.When the super-continent of Gondwanaland split up about 160 million years ago,Australia joined Antarctica and drifted towards the South Pole,where glaciers formed a barrier between it and other land masses.
Over the past 45 million years,Australia has moved away from Antarctica towards the equator and become warmer and more arid.About 35 million years ago,eucalypts began to displace the dense forests of the cool,damp Tertiary era.
Today Australian eucalypts account for more than half of all eucalypts found throughout the world.
The marsupials native to Australia have a different chromosome structure than mammals in other parts of the world.Typically,they suckle their young in a pouch.
Like the eucalypts,marsupials occupied a wide range of ecological niches in Australia.The first kangaroo marsupials seem to have appeared about 15 million years ago.They vary enormously in size and adaptation.A species of tropical kangaroo lives in trees,but most kangaroos are tough,efficient users of dry bush.
As the world climate warmed and glaciers melted,oceans gradually rose to their current level and the land bridges to New Guinea and Tasmania were cut.Corals colonised a flooded coastal plain,forming the Great Barrier Reef of Queensland.
Ancient plants still grow in the wild.Large "Antarctic" tree ferns are common in damp,shaded gullies on the south sides of ridges.Cycad palms form an understorey to tall,silvery spotted gums (eucalypts) along the south-east coast.Rare relics from earlier geological eras are found in small,special habitats,such as desert canyons.
Pressure on native habitats from agriculture and introduced pests like the fox and rabbit have resulted in extinctions of some native species in the past 200 years.Australia now has a strong scientific and legal framework to deal with these issues.Australians care about their unique environment.
History
More than 60 000 years before the arrival of European settlers,Aboriginal and Torres Strait Islander peoples inhabited most areas of the Australian European settlement in 1788.However,there were an estimated 300 000 Indigenous Australians living on the continent.
Until recently,Western historians focused on early European contact with the Australian continent during the 16th and 17th centuries.
In recent years this approach has been balanced by the recognition that Asian and Oceanic explorers and traders had contact with Indigenous Australian people long before the European expansion into the eastern hemisphere.
After the American War of Independence,Britain looked to establish new penal settlements to replace the north Atlantic colonies.The First Fleet of 11 ships with 1500 aboard,half of them convicts,arrived at Botany Bay in January 1788.Sydney grew from that first British penal settlement.
Transportation of British convicts to New South Wales ceased in 1840,but continued to Western Australia until 1868.About 160 000 convicts arrived over 80 years.That compares with free settler arrivals as high as 50 000 a year.
During the 1850s,settlement was boosted by gold rushes.Scarcity of labour,the vastness of the bush,and new wealth based on farming,mining and trade all contributed to the development of uniquely Australian social institutions and sensibilities.
In 1901 the Australian colonies federated to become the Commonwealth of Australia.As in Canada,the British monarch remains the monarch of Australia,which is now an independent,democratic nation with a tradition of religious tolerance and free speech.
Immigration
Australia"s culturally diverse society includes its Indigenous peoples and settlers from countries all around the world.
Immigration is an important feature of Australian society.Since 1945,over six million people from 200 countries have come to Australia as new settlers.Migrants have made a major contribution to shaping modern Australia.People born overseas make up almost one quarter of the total population.
The federal government sets immigration intake numbers on a yearly basis.Australia"s immigration policies are non-discriminatory and all applicants to migrate must meet the same selection criteria.

Economy
Australia has had one of the most outstanding economies of the world in recent years.As a high-growth,low-inflation,low interest rate economy,it is more vibrant than ever before.There is an efficient government sector,a flexible labour market and a very competitive business sector.
With its abundant physical resources,Australia has enjoyed a high standard of living since the nineteenth century.It has made a comparatively large investment in social infrastructure,including education,training,health and transport.
The Australian workforce has seen many improvements over the last decade,leading to the surge in productivity in the 1990s.The complex and centralised award based industrial relations system has given way to a more decentralised one with many employees working under workplace agreements tailored to meet enterprise needs.

information could be (sent through another part).sent不是动词吗?为什么be后?

sent是动词啊,是send的过去式和过去分词形式
could是情态动词,情态动词必须后面接实义动词一起构成谓语(即复合谓语)
be后事构成被动语态即be done 结构
括号意思是“通过另一部位(被)发送”

after 2 females leave a party ,there are twice as many males as females.then 9 males leave and there are twice as many femails as males.The totle number of prople left at the party after the 9 males leave.
twice as many ..as 到底是谁是谁两倍,

twice as many males as females男人是女人的两倍多.
从后面推起,原来男为女的2倍,离开九人后男为女的一半,设男为X个女为Y个,9=3/2(Y-2),Y=8
Y-2=X/2,所以X=12.

人类可以长生不老吗?怎样做才可以延长寿命?人类长生不老的重点是什么?
有谁知道人类长生不老要做到几点,多少年才可以做到,长寿要怎样做,怎样才可以长生不老,例如基因科隆,转基因.越详细越好!
现在的科隆技术这么好,科隆人体然后移植我们的大脑是可以的我认为;还有根据研究细胞有选择死亡的物质,消除他不知道可不可以.还有啊,人类的意识真的不可以保存并使他长存么?你们帮找下,谁找到好的就给分啊!

我敢打赌,现在还活着的人中,肯定会有不少人能活到1000岁!”上个月,英国“基因狂人”奥布里·德格雷发出了这个惊世骇俗的断言.
实际上,这不是41岁的德格雷最惊世骇俗的言论.早在今年一月份,他就预言说,2100年后出生的“未来人类”有望活到5000岁.
5000岁是德格雷大胆的预言,1000岁则是德格雷的坚定信念.德格雷宣称,他已经破解了人类老化的公式,分析出导致人类老化的七个因子,如果利用分子生物学、基因学和纳米技术对这七个因子成功进行干预,就可以停止老化过程,从而令人类的寿命延长到不敢想象的地步.
德格雷说,他相信他的研究小组能够在10年内为老鼠延长寿命,然后再花10年将新技术运用到人类身上.那样的话,现年60岁左右的人就有望享受他的研究成果.
他是个天才,还是个疯子?
美国“滑石板”新闻网站(www.slate.com)的文章煞有介事地称,“最起码,你要相信,德格雷是一个严肃的科学家”.
如果一个又高又瘦、留着2尺长棕色络腮胡子的家伙在酒吧里对你说,他是一名科学家,能帮助你实现长生不老的愿望,你肯定会想,这是个疯子.
奥布里·德格雷给人留下的就是这种印象,尽管他的确是英国剑桥大学的基因学家,并被美国麻省理工大学评为“全球最优秀的‘老化学家’”.
没有导师的博士研究生
德格雷是一名半路出家的生物学家,他原来是一名软件工程师.1985年,他从剑桥大学拿到了计算机学位.1991年,德格雷同一位校友结婚,他的妻子是一名基因学家,在剑桥大学基因学院工作.随即,德格雷被邀请加入基因学院做“计算机助理”,帮助学院建设基因数据库.
很快,德格雷对妻子的研究领域产生了兴趣,于是整天泡在图书馆里猛啃基因学的文献.书读得越多,德格雷就越坚信,传统的“老化学家”们一直缺乏整合整个“老化学”研究领域的“大视角”,在这个领域,一直没有人整合各个分支的研究成果,并将其整合到一起.
于是,德格雷决心来做这个整合的工作,“我认为我能够做出贡献”.
德格雷的第一个“贡献”就引起了基因学界的轰动.1997年,他发表了一篇论文,对线粒体(细胞内部的“动力工厂”,给细胞的提供能量,维持各项活动)的老化过程提出了新解释.德格雷的工作得到了一致认可,生物学家承认,他的确找到了一个新发现.

这是可能的.人体的衰老主要是由细胞再生能力的逐步减弱或逐步失去功能.
而造成衰老最主要的原因,就是自由基.在周衰老的斗争中,植物已经找到了对付自由基的有效方法,而动物还不能.因此植物的寿命很长,但终于有一天也会死亡.

我赞成!初中上生物的时候我就希望有人可以控制细胞无限再生了!
