本文是一篇说明文，全文为“分—总”结构。文章主要介绍了野生动物进入城市这一现象的原因和野生动物在城市中的生存状况以及遇到的问题等，说明了人类城市化进程给野生动物带来的影响，最后强调人类应理解、欣赏野生动物并与其和谐相处。课文由事件到分析，再到结论，这种行文模式在说明文中极为常见，读文时应分析首段的事例明意图，梳理主体部分的阐述明道理，根据尾段的结论明主旨。 02 课文写法借鉴 (一)赏用词之妙 1．As our cities become greener， they offer increasingly appealing spaces to animals looking for new habitats. 赏析：本句中increasingly一词与前面的greener相呼应，强调了城市对动物们来说越来越有吸引力的原因。 2．There is evidence that urban racoons are more intelligent than their wild cousins， as they frequently have to figure out difficult problems such as how to open rubbish bins and other containers which they would not find in the wild. 赏析：本句中使用了such as举例阐明了前面的difficult problems，使读者更容易理解城市里的动物为了在城市生活下去不得不做出的改变。 [提能训练|完成句子] ①With the environment getting worse， water is becoming ___ ____________________________. 随着环境的恶化，水正成为越来越珍贵的资源。 ②It protects against environmental factors ___________________. 它可以防范风、太阳等环境因素的危害。 increasingly precious resource an such as wind and sun (二)赏句式之高 1．However true this is， we also need to consider that some of these so-called “urban animals” have never moved at all — it's we humans who have moved into their territory. 赏析：本句中never ...at all及强调句型的使用，着重强调了动物进入城市的原因是由人类造成的。 2．There is evidence that urban racoons are more intelligent than their wild cousins， as they frequently have to figure out difficult problems such as how to open rubbish bins and other containers which they would not find in the wild. 赏析：本句中使用了that引导的同位语从句，对名词evidence进行解释说明，向读者说明和野生的浣熊相比，城市里的浣熊更聪明；同时运用as引导的原因状语从句解释了城市里的浣熊聪明的具体原因，以及which引导的定语从句进行补充说明。 3．Only then can we look towards harmoniously sharing our urban habitats. 赏析：此处倒装句的使用使作者的观点更加鲜明突出：若人类不理解动物、不懂得欣赏动物，我们就无法与动物和谐共享我们的城市栖息地。 [提能训练|完成句子] ①I never buy things online at all — _________________________ I buy what I need. 我从不在网上买东西——我需要的东西都是在超市里买的。 ②____________________ Earth is warming at an unprecedented rate.有证据表明，地球正在以前所未有的速度变暖。 ③_____________________ the significance of protecting wild animals.直到那时我们才意识到保护野生动物的重要性。 it is in the supermarket that There is evidence that Only then did we realize (三)赏修辞之功 With foxes in London， mountain lions in San Francisco and wild pigs in Hong Kong， it is almost as if our cities are being taken over by wild animals. 赏析：本句中的take over运用了拟人手法，把事物人格化，突出了城市中野生动物越来越多的现象。 [提能训练|翻译下列句子] ①The wind whispered through the grass. _____________________ ②The horses thundered across the valley floor. _____________________ ③The flowers nodded in the breeze. ___________________ 风在草丛中窃窃私语。 马群从谷底呼啸而过。 花儿在微风中点头。 (四)赏描摹之韵(场景描写) The crime took place in a seaside suburb of Cape Town.Spotting the car with its window left open， the greedy thief didn't hesitate.Within seconds， he had reached inside and run away with a bag of shopping.No matter how many crimes he committed， the police were powerless to arrest him.You see， this was no ordinary criminal：it was a chacma baboon. 赏析：此处作者运用幽默风趣的语言描述了发生在开普敦一个海滨郊区的一起“犯罪”活动，引发读者阅读的兴趣。文中使用了spot， greedy， didn't hesitate， within seconds， reach， run away等一系列的词语准确而又形象地描绘了狒狒的形象和动作，使得“狒狒盗窃”这一场景活灵活现，跃然纸上。 [提能训练|完成下列场景描写的语段] ①Mac ___________ his bike and ________ for the back door of the RV.It was locked.He _____ around to the passenger door， but it was locked， too， so he ______________ through the open window. 迈克跳下自行车冲向房车后门。门锁着。他跑向副驾驶室的门，但门也锁上了，所以他开始从开着的窗户爬进去。 jumped off dashed ran began to climb ②Mac was _________ hard now.He ___________________ passing motorists but was careful not to slow down. 现在迈克在使劲地蹬着自行车踏板。他向路过的司机挥手大喊，但同时小心地不减速。 pedaling waved and yelled at 03 美文阅读润心 在距离北极点约1 000 公里的挪威斯瓦尔巴群岛的地下深处，有一座保存全世界农作物种子的贮藏库。它也被形象地称为“末日粮仓”“世界末日种子库”。这座种子库可存储22.5亿颗种子，旨在保护农作物多样性和应对小行星撞击地球、核战争等灾难，是确保全球粮食安全的最后一道防线。种子库建于冻土地带的岩石中，因此不受气温变化的影响。其位置高于海平面130米左右，即便格陵兰的冰盖融化，或者南极洲的冰层完全消融，海平面上升61米，它仍然安然无恙。 Close to the North Pole， the remote and rocky Plateau Mountain in the Norwegian archipelago of Svalbard seems an unlikely spot for any global effort to safeguard agriculture.In this cold and deserted environment， no grains， no gardens， and no trees can grow.Yet at the end of a 130-meter-long tunnel cut out of solid stone is a room filled with humanity's most precious treasure， the largest and most diverse seed collection — more than a half-billion seeds. A quiet rescue mission is under way. With growing evidence that unchecked climate change will seriously affect food production and threaten the diversity of crops around the world， the Svalbard Global Seed Vault (地窖) represents a major step towards ensuring the preservation of hundreds of thousands of crop varieties.This is a seed collection， but more importantly， it is a collection of the traits found within the seeds：the genes that give one variety resistance to a particular pest and another variety tolerance for hot， dry weather. ① Few people will ever see or come into contact with the contents of this vault. In sealed boxes，behind multiple locked doors，monitored by electronic security systems，enveloped in below-zero temperatures， and surrounded by tons of rock ， hundreds of millions of seeds are protected in their mountain fortress.Frozen in such conditions inside the mountain， seeds of most major crops will remain viable for hundreds of years， or longer.Seeds of some are capable of retaining their ability to grow for thousands of years. ② Everyone can look back now and say that the Seed Vault was a good and obvious idea， and that of course the Norwegian government should have approved and funded it.But back in 2004， when the Seed Vault was proposed， it was viewed as a crazy， impractical， and expensive idea. We knew that nothing would provide a definite guarantee.But we were tired， fed up， and frankly scared of the steady losses of crop diversity.The Seed Vault was built by optimists who wanted to do something to preserve options so that humanity and its crops might be better prepared for change.If it simply resupplied seed gene banks with samples those gene banks had lost， this would repay our efforts. The Seed Vault is about hope and commitment — about what can be done if countries come together and work cooperatively to accomplish something significant， long-lasting， and worthy of who we are and wish to be.

She even made friends at the center — another injured swan.Sadly， even with all that loving care， the swan didn't pick up.Two months after Rojas came to her aid， she passed away.It's a disappointing ending， but the real story is just how far some people are willing to go to save a swan in the big city.In all， Rojas traveled two hours by foot， car， and subway while dragging her bike. 语篇解读：本文是一篇记叙文。文章讲述了Ariel Rojas营救一只受伤天鹅的故事。 1．What does the underlined word “predator” in paragraph 1 mean？ A．A potential volunteer.　 B．A likely audience. C．A potential killer. 　 D．A likely helper. √ 解析：词义猜测题。根据画线词后文“and attack her ”以及“but as she approached this one， it didn't move ”可知，正常情况下天鹅会把她当成可能的敌人而攻击她，从而推知句中画线单词意思是“可能的敌人”，C项“潜在的杀手”与之最为接近。 2．According to the passage， which of the following statements is true？ A．It was easy for Ariel to carry the little swan. B．The swan ran into her way and was hit. C．Rojas sent the swan to the center all by herself. D．The swan was kindly and lovingly treated. √ 解析：细节理解题。根据最后一段中的“Sadly， even with all that loving care， the swan didn't pick up.”等内容可知，这只天鹅是温顺的，并且受到了热情体贴的关爱。 3．Which of the following can best describe Rojas？ A．Kind-hearted and imaginative. B．Caring and helpful. C．Strong-minded and energetic. D．Positive and creative. √ 解析：推理判断题。根据最后一段中的“It's a disappointing ending， but the real story is just how far some people are willing to go to save a swan in the big city.In all， Rojas traveled two hours by foot， car， and subway while dragging her bike.”可知，Rojas为了救助天鹅，不辞劳苦，从而推知，她是个有爱心、乐意施助的人。 4．What may be the best title for the passage？ A．A Poor Swan Saved by a Taxi Driver B．A Volunteer Loving and Saving Birds C．Loving Honks to Save a Poor Swan D．A Poor Swan Surrounded with Strangers √ 解析：标题归纳题。通读全文可知，文章讲述了Ariel Rojas在散步时发现了一只需要救助的天鹅。最终在陌生的司机等人的接力帮助下，她成功将天鹅送到了康复中心。这个故事展示了人们为拯救野生动物所付出的努力。C项“挽救天鹅的爱的鸣笛”为最佳标题，充分体现了在Ariel Rojas救助天鹅途中各个陌生司机给予的帮助和Ariel Rojas的爱心。 B To grow sugary dates (椰枣)in the sand， Siwa's farmers must first make the desert suitable for farming.As an oasis (绿洲) in Egypt， Siwa has been home to humans for thousands of years.Since ancient times， the oasis has had farms producing some of the most valuable dates in Egypt， and sugary dates have appeared on Egyptians' tables. The desert environment in Siwa is not quite fit for plants to grow.For example， the water there contains much salt.However， with local people's efforts， the Siwa oasis contains complex agricultural fields， where date trees， crops and other plants grow in harmony.That impressed me a lot during my visit to the oasis.To make a new piece of field， farmers first move away the top soil and replace it with a mixture of sand and waste matter from animals.The first plants are medicinal plants.Then， farmers plant date trees and olive trees.These farming skills are passed down from generation to generation. To grow date trees is demanding.And it takes 10 years for a new date tree to grow up， but once it does， the tree produces generous fruit：around 110 pounds of dates per year.Each farmer picks dates with the skilled hands.They climb the trees using nothing more than a belt.In total， Siwa gets more than 25，000 tons of dates from 280，000 trees per year. The dates can be eaten fresh， or made dry.Every part of the date tree is important in Siwa， from leaves made into beds and boxes to wood used to build houses.And then， of course， there's the fruit itself.The dates can be cooked with goat meat or mixed with eggs for breakfast.They can also be mixed with flour， water， and olive oil， and boiled slowly to make a local dessert. Local farmers once developed many unique date varieties， which their camels carried to Cairo.But later many of those varieties ________. And today only several major varieties remain and some have become quite rare and been at risk.The construction of a road in the oasis made the survival of local agricultural tradition even harder. 语篇解读：本文是一篇记叙文。文章主要讲述了Siwa绿洲的农民克服地理环境上的困难，用智慧和努力在沙漠上种甜椰枣的故事。 perished 5．What can we learn about sugary dates from paragraph 1？ A．They have existed for a long time. B．They prefer the desert environment. C．They're introduced to Egypt from abroad. D．They're the most valuable fruit in Egypt. 解析：细节理解题。根据第一段中的“Since ancient times， the oasis has had farms producing some of the most valuable dates in Egypt， and sugary dates have appeared on Egyptians' tables.”可知，甜椰枣已经存在很长时间了。 √ 6．What impressed the author a lot during his visit to Siwa？ A．The great variety of plants grown there. B．The hard but happy life of local people. C．The difficulty in developing the local agriculture. D．The farmers' wisdom and contribution to farming. √ 解析：细节理解题。根据第二段第三、四句可知，作者在Siwa访问期间，当地农民的智慧和对农业的贡献给作者留下了深刻的印象。 7．What do the figures mentioned in paragraph 3 show？ A．It is easy to pick dates from the trees. B．It is worth the effort to plant date trees. C．It costs a lot to grow date trees in the oasis. D．It is necessary to develop agriculture in Siwa. √ 解析：写作意图题。根据第三段的首句(主题句)可知，本段中提到的数字是为了说明种植椰枣树是值得的。 8．What does the underlined word in the last paragraph mean？ A．Improved.　　　　　　 B．Died. C．Became expensive. 　 D．Remained unique. √ 解析：词义猜测题。根据最后一段可知，许多椰枣品种都消失了，现在仅有主要品种存活着，而且有些品种还很少见。由此推测，画线单词表示“死亡”，与died同义。 Ⅱ.阅读七选五 Urban Wildlife Cities are diverse ecosystems.In addition to visitors from the wild， a large number of species share our urban areas.As our cities spread， we need to think about what it is like for other species to have human neighbors. Cities are built for humans. ____ For example， most city parks are kept neat and tidy so that humans will find them beautiful.But when we cut grass or plant flowers， we destroy natural habitats. 9 ____ When a bridge in Austin， Texas was repaired， engineers added small gaps running along the length of its bottom.This made a good home for bats， and soon the bridge was the home of thousands of bats. ____ Now， they have come to value their winged (有翼的) neighbors.The bats are a tourist attraction， and they eat lots of bugs every night. 10 11 There are also structures built with the aim of bringing wildlife into the city.The Olympic Forest Park is a good example.The park used native plants and created open， natural space for wildlife.The result is a zone in Beijing with over 160 species of birds.In many ways， the park is the opposite of a zoo. ____ If we learn to share our space， we can become better neighbors to the wildlife around us. ____ Our own future will be endangered， too. 12 13 A．They are built to protect birds. B．Our actions sometimes help other species. C．If we do not， more species will become extinct. D．They do not always provide suitable habitats for wildlife. E．Instead of being kept in cages， wildlife can move freely. F．At first， people were afraid of the bats and tried to get rid of them. G．They would sit on it and their droppings would fall into the water. 语篇解读：本文是一篇说明文。城市是多样化的生态系统，我们需要考虑其他物种与我们为邻的情况。 9．选D　根据空前一句及空后所举的例子，尤其是最后一句“但当我们割草或种花时，我们破坏了自然栖息地”可知，选项D符合语境。 10．选B　根据空后所举的例子，尤其是“这为蝙蝠提供了一个很好的家园，很快这座桥就成了成千上万只蝙蝠的家园”可知，选项B符合语境。 11．选F　根据空后一句中的时间标志词“Now”可知，空处所填句子应与下文内容形成对比，故选F。 12．选E　根据本段的内容——尤其是空前的“The result is a zone in Beijing with over 160 species of birds.In many ways， the park is the opposite of a zoo.”——可知，空处内容应与空前一句存在话题一致、内容上承接的关系，故选E。 13．选C　空前一句表述人类与野生生物共享城市空间的好处，空后一句与空前一句形成对比，再结合空后一句中的“too”可知，选项C符合语境。 本课结束 更多精彩内容请登录：www.zghkt.cn $
