Period 2 Using language(1)—Grammar Into the wild Unit 5 1 内容索引 情境导读 语法精讲 达标检测 作业2 情境导读 阅读以下短文，体会加颜色部分，完成下面的练习 Do you remember a time ①when you had no worries stopping you from getting a good night’s rest？Unfortunately，your happy childhood is probably a thing of the past. A recent study has found that many people suffer from sleep problems. Some are unable to fall asleep，some wake up in the middle of the night，and others simply do not get enough sleep. One of the reasons ②why people fail to get a good night’s sleep is pressure from school or work. Noise pollution and light pollution in big cities may also contribute to sleep problems. In the short term，people with sleep problems often feel tired and have trouble concentrating. In the long term，they may be at increased risk of having a poor memory，being overweight and suffering a heart attack. Sleep problems are especially dangerous for teenagers. They are still growing and night is the time③when their bodies grow faster.Teenagers who do not sleep well may experience situations ④where body development slows down and their health suffers. So，if you have trouble getting a good night’s sleep，it might be time to make some changes in your lifestyle. 以上加颜色的定语从句的关系词都是关系副词，分别是：_____________ ______，这些词在从句中都作状语，如果先行词是表示时间的名词，关系词要用 ，如： ；如果先行词是表示地点或抽象地点的名词如situation，stage等时，关系词要用 ，如： ；如果先行词是reason，关系词要用 ，如： 。 返 回 when，where， why when ①③ where ④ why ② 语法精讲 定语从句(二) 一、语法图解 二、关系副词引导的定语从句 关系副词 先行词 功能 when 表示时间的名词 时间状语 where 表示地点的名词 地点状语 why reason(s) 原因状语 (1)关系副词when引导定语从句时，先行词往往是表示时间的名词(如time，day，week，month，year等)，关系副词在从句中作时间状语。 I hope there are moments when I forget all my worries and pains. 我希望有那么一刻，我能忘记所有的烦恼和痛苦。 Tom will never forget the days when he lived in China with his family. 汤姆永远不会忘记他和家人在中国生活的日子。 (2)关系副词where引导定语从句时，先行词往往是表示地点的名词(如place，room，house，spot，school，country等)，关系副词在从句中作地点状语。 They went into the hall where the meeting was being held.他们走进正在开会的大厅。 The professor wrote a letter where he explained how he found the solution to the problem. 教授写了一封信，在信中他解释了他是如何找到这个问题的解决办法的。 注意：当先行词是抽象名词，如case，point，condition，situation等，且关系词在从句中作地点状语时，仍然用where引导定语从句。 We have reached a point where a change is needed.我们已经到了需要做出改变的地步。 What are the situations where body language is the only form of communication? 在哪些情形下肢体语言是唯一的沟通方式？ You will reach a point in any project where you just want to get the thing finished.在任何一个项目中，你都会达到一个你只想把事情做完的阶段。 (3)关系副词why引导定语从句时，先行词常为reason，关系副词在从句中作原因状语。可用for which代替。 Do you know the reason why(＝for which) swallows migrate to the south? 你知道燕子迁徙到南方的原因吗？ 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。 [即时演练1]　用合适的关系词填空 1.It was 10 o’clock they went out of the cinema. 2.Can you tell me the reason you didn’t come to the party? 3.The factory my father works is not far from our village. 4.There was a time Anne was so crazy about everything to do with nature. 5.Singapore is one of the few countries people drive on the left there. 6.She dreams of a life she can travel around and experience different cultures. when why where when where where 三、注意事项 表示时间、地点及原因的名词作先行词时，定语从句可用关系代词引导，也可用关系副词引导。若先行词在定语从句中作状语时，应用关系副词；若先行词在定语从句中作主语或宾语时，则应用关系代词。试比较： Do you remember the days when we chatted with each other all night？你还记得我们整夜聊天的那些日子吗？(when在从句中作状语) Do you remember the days that/which we spent together on the farm? 你还记得我们在农场一起度过的那些日子吗？(that或which在从句中作spent的宾语) The talented pianist returned to the city where he grew up.这位天才钢琴家回到了他成长的城市。(where在从句中作状语) The talented pianist returned to the city that/which he visited last year. 这位天才钢琴家回到了他去年去过的城市。(that或which在从句中作visited的宾语) I don’t know the reason why he didn’t turn to his good friend for help yesterday.我不知道昨天他为什么没向他的好朋友求助。(why在从句中作原因状语) I won’t listen to the reason that/which you have given us.我是不会听你给我们的那个理由的。(that或which在从句中作give的直接宾语) [即时演练2]　用合适的关系词填空 1.The secret meeting was held in the house he used to live. 2.This is the house was built by my grandfather forty years ago. 3.The reason he explained at the meeting was not sound. 4.The reason he was late was that he missed his train. 5.I will never forget the days we spent together. 6.Newspapers are trying to attract readers in an age most people read news online for free. 返 回 where which/that that/which why that/which when 达标检测 There was a time 1.

Donkeys tend to live longer than horses live，and this comes down to biological reasons and species differences.As equines(马科动物) age，it becomes more difficult for them to bite their food into pieces and take in the energy they need to maintain a healthy body weight.For horses，this can be a real problem.However，a donkey’s digestive system is much more efficient，meaning a donkey only requires 50%－75% of the food that a horse of a similar size would need.Their ability to get the energy out of their food will be able to help them survive on a diet that wouldn’t support a horse of the same size and weight. Domestic donkeys first came from the African wild donkeys，who lived in the difficult，dry environment of areas of Northeast Africa.This means they are better suited feeding on bushes and are better suited surviving on wild vegetation. That is one of the reasons why domestication has helped both species，and how specific feed，such as short cut，enables both species to get the nutrition they need.At international animal welfare charity，The Donkey Sanctuary，part of their ongoing care as donkeys age is to alter their diet as suitable.The care they get there will hopefully see them living a healthy，happy life. 1.Over what age do donkeys start to be considered old? A.20. B.30. C.40. D.50. √ 细节理解题。根据文章第一段中“It’s generally considered that an aged donkey is one that is over 20 years old”可知，超过20岁的驴就被认为是老龄驴。故选A。 解析 2.What affects how long a domestic donkey lives according to the text? A.Its size. B.Its food choice. C.Which country it comes from. D.Whether it’s a pet or a working animal. √ 细节理解题。根据文章第一段中“It’s generally considered that...This is more the case in donkeys kept as pets rather than as working donkeys.”可知，作为宠物饲养的驴比作为工作动物饲养的驴活得更久。故选D。 解析 3.Why do donkeys live longer than horses? A.Donkeys like eating short-cut plants. B.Donkeys have better digestive ability. C.Donkeys prefer various kinds of food. D.Donkeys have better living conditions. √ 推理判断题。根据文章第二段中“However，a donkey’s digestive system is much more efficient，meaning a donkey only requires 50%－75% of the food that a horse of a similar size would need.”可知，驴的消化能力更好，意味着驴能够从食物中获得比马更多的能量，从而寿命更长。故选B。 解析 4.What does the underlined word “alter” in the last paragraph mean? A.Increase. B.Reduce. C.Doubt. D.Change. √ 词义猜测题。根据画线词alter前文的内容“That is one of the reasons why domestication has helped both species，and how specific feed，such as short cut，enables both species to get the nutrition they need.”可知，前文提到需要特定的喂养方式，因此随着驴年龄的变化，护理它们的工作也在变化，需要改变它们的饮食，故此处画线词alter与D项“改变”意思相近。故选D。 解析 B(此篇精读) (2025·湖北高中联盟高一上期中) With human activities expanded，more and more animals are getting affected.In order to survive hunger，they have to leave their habitat.A group of wandering wild elephants have become an overnight Internet hit globally. 语篇解读　本文是一篇新闻报道。文章讲述了一群流浪的野生大象一夜之间在中国和全球互联网上引起轰动，并且分析了大象流浪的原因以及引发的关注和影响。 While the original group was made up of 16 elephants，two decided to return home after a week.The rest continued their journey northward，stopping only for a short break in November 2020 to allow a newly-born elephant and its mother to recover. Since leaving the reserve，the elephants have walked over 500 kilometers.Along the way，they entered farms for food and water，walked through urban streets，and even paid a visit to a car dealership and a retirement home.No animals or people were hurt.However，they destroyed more than $ 1 million worth of crops. Researchers are not sure why the elephants decided to leave or where they are headed.While they are known to leave their habitat in search of food，this is the longest migration of wild elephants recorded in China. Because of this，some guess that the elephants may be lost.However，others think the elephants were forced to move due to deforestation(砍伐森林).Successful conservation efforts have almost doubled the elephant population in the Xishuangbanna National Nature Reserve.However，their natural habitat has been greatly reduced. “As their populations increase，they search for more food，” Becky Shu Chen said.“You could say that the increase in agricultural land in their region is like finding a big sweet shop，right on their doorstep.” The wandering herd’s search for a suitable home was noticed by locals who eagerly followed their daily movements on social media.Adam Chang，assigned to deliver food to the elephants，says，“Before this meeting，I just felt curious about animals.Now，I think I would volunteer in animal rights groups to preserve those giant creatures.” 5.Why did the wild elephants stop temporarily in November 2020? A.To enjoy the food given by local people. B.To pay a visit to a car dealership. C.To figure out whether they were in the right direction. D.To wait for a baby elephant and its mom to recover. √ 细节理解题。根据第一段最后一句“The rest continued their journey northward，stopping only for a short break in November 2020 to allow a newly-born elephant and its mother to recover.”可知，野生大象在2020年11月暂时停止活动的原因是等待新生的小象和它的妈妈恢复。故选D项。 解析 6.Which is TRUE according to the text? A.Scientists know why the elephants leave their home. B.The elephants couldn’t find their way home. C.Elephants population has decreased because of human activities. D.This group of elephants did great damage to the crops during the migration. √ 细节理解题。根据第二段最后一句“However，they destroyed more than $ 1 million worth of crops.”可知，这群大象在迁徙过程中对庄稼造成了极大的破坏。故选D项。 解析 7.What do Adam Chang’s words in the last paragraph mean? A.The elephants have the rights to move. B.The elephants help to raise people’s awareness of animal protection. C.The elephants are helped by locals to find a suitable home. D.The elephants are annoyed of being followed. √ 推理判断题。根据最后一段中“Before this meeting，I just felt curious about animals.Now，I think I would volunteer in animal rights groups to preserve those giant creatures.”可知，在与大象群见面前，他只是对动物好奇。但现在他愿意加入动物权利保护团体来保护那些体型庞大的生物，由此可推知，流浪的大象群提高了人们保护动物的意识。故选B项。 解析 8.What is the text mainly about? A.China’s wild elephants are always on the move. B.China’s wandering wild elephants attract the world. C.China’s wandering elephants are losing their way. D.China’s wild elephants are touring through cities. √ 主旨大意题。根据文章第一段中“A group of wandering wild elephants have become an overnight Internet hit globally.”以及全文可知，文章讲述了一群流浪的野生大象一夜之间在中国和全球互联网上引起轰动，即中国流浪的野生大象吸引了全世界。故选B项。 解析 1.overnight(合)＝over＋night adj.一夜之间的，突然的 2.hit熟义：v.打击，撞击 生义(文义)：n.很受欢迎的人或事物 3.nature n.自然 →natural adj.自然的 4.suitable(派)＝suit＋able adj.合适的 词汇积累 Researchers are not sure why the elephants decided to leave or where they are headed. 分析：此句是复合句。why 和where 引导宾语从句。 翻译：研究人员不确定大象们决定离开的原因，也不知道它们要去往何处。 句式分析 (2025·浙江绍兴高一上期中) How to Be a Successful Teenager Everybody wants to be successful in life. 语篇解读　本文是一篇说明文。文章主要介绍了青少年取得成功的一些方法。 Ⅳ.七选五阅读 A.Live life to the fullest.
