Unit 5 Into the wild对于动物的灭绝，很多人猜测是气候的原因，其实，有时候人类才是动物生存最大的威胁。

我们要保护动植物，与它们和谐相处。

Climate change, not human hunting, may have wiped out the thylacine (袋狼), according to a new study based on DNA from thylacines' bones.The meateating marsupials (有袋动物) died out on mainland Australia a few t housand years ago, but survived in Tasmania, an island of southeast Australia se parated from the mainland, until the 1930s. Until then, scientists had believed the cause of this mainland extinction (灭绝) was increased activity from native Australians and dingoes (Australian wild dogs)．Scientists behind the University of Adelaide study, which was published in t he Journal of Biogeography on Thursday, collected 51 new thylacine DNA samples f rom fossil bones and museum skins — the largest data set of thylacine DNA to da te. The paper concluded that climate change starting about 4,000 years ago — in particular drier seasons caused by the weather systemsknown as El Niño — Southern Oscillation (南方涛动) — was likely the main cause of the mainland extinction.The ancient DNA showed that the mainland extinction of thylacines was rapid, and not the result of loss of genetic diversity. There was also evidence of a p opulation crash in thylacines in Tasmania at the same period of time, reducing t heir numbers and genetic diversity.Associate Professor Jeremy Austin said Tasmania would have been protected fr om mainland Australia's warmer, drier climate due to its higher rainfall. He arg ued that climate change was “the only thing that could have caused, or at least started, an extinction on the mainland and caused a population crash in Tasmani a.”“They both happened at about the same time, and the other two things that h ad been talked about in the past that may have driven thylacines to extinction on the mainland were dingoes and humans. So the only explanation left is climate change. And because the population crash happened at the same time and the speci es went extinct on the mainland, our argument is that there's a common theme the re and the only common theme is that there is this change in climate.”。

Unit 5 Into the wild动物是人类的朋友。

保护野生动物，不让它们遭受灭绝的厄运是人们的责任。

Wild animals are our friends, but many of them are getting fewer and fewer.We should try to protect them.The four animals below are now in danger.Tibetan Antelopes(藏羚羊)Tibetan antelopes are mediumsized animals.They mainly feed on grass.They are usually found in groups of about 20.They are killed for their wool, which is warm, soft and fine and can be made into expensive clothes.The number of them is dropping year by year.There are less than 75，000 Tibetan antelopes left in the world, down from a million 50 years ago.Golden MonkeysGolden monkeys are mainly found in Sichuan, Gansu, Shanxi provinces and Shennongjia mountainous area of Hubei Province.They all have goldenorange fur.They move around in the daytime, usually in groups of as many as 100 to 200 heads, or 20 to 30 heads.But people are destroying the environment where they live.Trees and bamboos are disappearing, so golden monkeys have less and less to eat.ElephantsElephants are very big and strong.They are bigger than any other animal on land.They are gray and have long trunks and tusks.They have poor eyesight, but very good hearing and smell.They can lift heavy things and break down branches with their trunks.Now, there are very few elephants in the world.The number of them is becoming smaller and smaller because their living areas are used for farming.WolvesWolves are not very big.They have gray fur.Wolves have very good eyesight, hearing and smell.Wolves' food is various.They eat animals, insects and snails.They arefriendly to each other and hardly attack people.They do not kill for fun.Wolves are in danger, too.They are losing their living areas because people cut down forests.Soon they will have no home or food.[诱思导读]1．What are Tibetan antelopes killed for?They are killed for their wool.2．What happens to golden monkeys，elephants and wolves when they lose their living areas?The number of them becomes smaller and smaller.Section Ⅰ Reading (Starting out & Understanding ideas)Ⅰ.匹配下列单词的词性及汉语意思( )1.movement A．adv.终于，最终( )2.mass B．v.活下来，幸存( )3.measure C．v.量，测量( )4.position D．adv.不幸地，令人遗憾地( )5.determine E．v .测定，确定( )6.eventually F．n.动作，活动( )7.solution G．v.破坏，毁掉( )8.unfortunately H．n.位置( )9.destroy I．n.解决，解决方法( )10.survive J．adj.大量的，大规模的[答案] 1.F 2.J 3.C 4.H 5.E 6.A 7.I 8.D 9.G 10.BⅡ.选择下列句中词组的汉语意思( )2.The solution to the problem lies with you.( )3.I'll inform you by mail when necessary.( )4.The doctor told him to cut down on his drinking.( )5.All roads lead to Rome.( )6.Birds feed on nuts and berries in the winter.( )7.I do hope you'll be able to come to the wedding.( )8.John would, sooner or later, cause him in serious trouble.

2019_2020学年新教材高中英语Unit5IntothewildPartⅡUsinglanguage——定语从句(2)课件

二、主要用法精讲 1.when 指时间，在从句中作时间状语。它的先行词通常有：time, day, week, year 等
。 I can not forget the day when (on which) I first saw you. 我不会忘记第一次见到你的日子。 2.where 指地点，在从句中作地点状语。它的先行词通常有：place, street, house, city, country 以及一些抽象意义的名词，如 point, case, position, condition, situation。 This is the house where (in which) they lived a week ago. 这是一个星期前他们住过的房子。
4.why指原因或理由，它的先行词只有reason。 The reason why (for which) I don’t trust him is that he often tells lies. 我不信任他的原因是他常常撒谎。
如何区别关系代词和关系副词？
正确区分关系代词和关系副词，关键是要弄清楚它们在定语从句中担当什么成分，而不仅仅取决于先行词是什么。如果关系词在从句中作主语或宾语，就用关系代词；如果作定语，就用whose；如果关系词在定语从句中作状语，就用关系副词。
名师提醒这三个关系副词在意义上都相当于“介词＋which”结构： ①when＝on (in, at, during...) ＋which ②where＝in (at, on...) ＋which ③why＝for which

Period ⅠStarting out & Understanding ideas课前自学导引黑脉斑蝶的旅程许多动物在一年中的某些特定时期从一个地方迁移到另一个地方。

这种每年一次的活动叫作迁徙。

他们迁徙的目的是寻找食物，寻找伴侣，或者寻找更温暖的天气。

北美的黑脉斑蝶的迁徙是大自然中最令人惊奇的迁徙之一。

每年秋天，数以百万计的这些美丽的昆虫，有着精致的黑色和橙色翅膀，开始了漫长而艰难的旅程。

不知怎么地，它们成功地向南行进了4,000公里，到达了加利福尼亚或墨西哥。

然而，直到最近才有人知道它们是如何做到这一点的。

由华盛顿大学的Eli Schlizerman教授领导的一组科学家现在已经找到了答案。

他们发现黑脉斑蝶能分辨出白天的时间。

它用眼睛测量太阳的位置。

这两条信息——白天的时间和太阳在天空中的位置——使得蝴蝶决定它走的路。

最终，它成功到达了它过冬的地方。

解决黑脉斑蝶神奇能力之谜的办法出现在它陷入严重困境的时候。

在过去的几年里，其数量锐减了90%。

不幸的是，人类活动是黑脉斑蝶数量下降的主要原因。

在许多可以找到黑脉斑蝶的地方，人们正在破坏着自然环境。

他们砍伐树木，使用化学物质杀死黑脉斑蝶幼虫吃的植物。

然而，对黑脉斑蝶行为的研究带来了对这种生物更多的认识。

人们一直在共同努力记录它的迁徙情况，确保它有足够的植物食用。

如果这项工作奏效，黑脉斑蝶数量可能会再次增加。

我们对这种美丽的生物了解得越多，它生存的可能性就越大，并且可以在未来很长一段时间内保持其在自然界中的地位。
