Using Language
Unit 5
Into the wild
Students will understand how relative adverbs help express clear logical relationships in English descriptions of events or scenarios.
Students will be able to identify the functions of relative adverbs in sentences and correctly use them.
Teaching objectives
Students will learn to summarize the usage rules of relative adverbs independently by sorting out text-related examples.
Students will develop logical thinking and analytical ability to choose appropriate relative adverbs for different contexts.




The teaching focuses on enabling students to proficiently utilize the basic sentence components and patterns in practical language use, as well as mastering the key listening skill of accurately making notes of crucial information.
The anticipated difficulties lie in students' comprehensive application of various basic sentence structures and their accurate and rapid extraction of key information while listening.
Key and difficult points


PART Ⅰ
Grammar
Attributive clauses (Ⅱ)
Enjoy the song!
Remember the first day ______ I saw your face.
Remember the first day______you smiled at me.
There’s a place downtown______the freaks all come around. It’s a hole in the world.
Oh, she must be the reason_____god made a girl.
She is so pretty all over the world.
when
when
where
why
Look at the sentences from the reading passage and answer the
question.
1. What do “where”, “when” and “why” refer to in each sentence
“where” refers to “the places” in sentence (a).
“when” refers to “a time” in sentence (b).
“why” refers to “the main reason” in sentence (c).
Compare them with the following sentences and answer the questions.
2. What is the difference between the two groups of sentences
Sentences (a), (b) and (c) contain a clause defining a noun or pronoun in the sentence. Sentences (d), (e) and (f) are constructed with a pair of simple sentences, with one defining a noun or pronoun in the other sentence in each pair.
Compare them with the following sentences and answer the questions.
3. Why does the author choose to use sentences (a), (b) and (c) in the reading passage
Because there is a closer link and connection between the item and the clause defining it in sentences (a), (b) and (c). It will also make the passage clearer, and create an emphatic effect on the location, time and reason being defined.
Now look for more sentences with attributive clauses in the reading passage.
These two pieces of information—the time of day and the point where the sun is in the sky...
In many of the places where the butterfly can be found, people are destroying the natural environment.
...there may come a time when the number of monarch butterflies increases once again.
关系副词
关系副词 先行词 功能
when 先行词通常为表示时间的名词,如time、day、occasion 等。 作时间状语
where 先行词通常为表示具体或抽象地点的名词,如place、position、situation、point 等。 作地点状语
why 先行词通常为 reason(s)。 作原因状语
关系副词与关系代词的区别
对比维度 关系代词 关系副词
核心作用 连接主从句并替代先行词 连接主从句,说明从句时间、地点或原因
从句成分 作主语、宾语、定语(如who/whom/which/that/whose) 作时间、地点、原因状语(如when/where/why)
常见先行词 人或物 时间、地点、原因类名词
判断关键 从句缺主宾定→用关系代词(The book (which) I read) 从句主谓宾完整→用关系副词(The day when I arrived)
where的用法
关系副词 where 引导定语从句时,在从句中充当地点状语。其先行词既可以是 place(地方)、house(房子)、city(城市)、country(国家) 等具体地点名词,也可以是 society(社会)、situation(情形)、stage(阶段)、point(程度)、case(情况) 等抽象地点概念的名词。在多数情况下,where 可与 “介词 + which” 结构同义替换。
There comes a stage where you have to face the challenges alone.
作地点状语
= at which
注意:
当先行词为具体地点名词时,若关系词在定语从句中作主语或宾语,则需使用 that/which 引导定语从句;若关系词在从句中充当地点状语,则应用 where 引导。
作宾语:This is the house that/which he bought last year.(他去年买的房子)
作状语:This is the house where he lived for 10 years.(他住了十年的房子)
当先行词是抽象地点概念的名词时,若定语从句中缺少地点状语,则用where引导从句,此时 “where” 相当于 “介词 + which” 。
We are in a position where we must make a decision.
=We are in a position in which we must make a decision.
where的用法
when的用法
在定语从句中,关系副词 when 用于修饰表示时间概念的先行词(如 time、day、year、moment、period 等),在从句中充当时间状语,此时 when 通常可与 “时间介词 + which” 结构互换。
核心规则:先行词为时间名词;从句结构完整(不缺主语 / 宾语);when 在从句中相当于 “时间介词 + which”。
时间状语:I’ll never forget the day when (= on which) we met.
(从句主谓完整:we met)
宾语成分:I’ll never forget the day that/which (= 省略) we spent together.
(从句缺宾语:spent the day)
注意:
当先行词是时间名词时,定语从句看关系词在句中的成分确定,如作状语,则用when 引导;如关系词作主语或宾语,则用that 或which 引导。
I still remember the days when we chatted with each other all night.
I still remember the days that /which we spent together on the farm.
作状语
作宾语
when的用法
why的用法
在定语从句中,why专门用于表达原因,在从句内充任原因状语。其引导的从句通常修饰 reason、excuse 等明确表示原因或理由的先行词。绝大多数情况下,why 与 for which 可以相互替换。
She couldn't give a good excuse why she missed the deadline.
作原因状语
= for which
注意:
若先行词 reason 的关系词在定语从句中不作状语,而是充当主语或宾语,则用 that 或 which 引导定语从句
I won’t listen to the reason that /which you have given us.
作原因状语
宾语
why的用法
介词的选择
1. 依据先行词与从句中动词的搭配来选择
This is the house where I lived last year.
=This is the house in which I lived last year.
2. 依据先行词与从句中名词的搭配来选择
I know the reason why he left.
=I know the reason for which he left.
“live” 常与 “in” 搭配,构成 “live in”
“reason” 常与 “for” 搭配,构成 “for the reason”
3. 依据先行词所表达的含义来选择
This is the city where I was born.
=This is the city in which I was born.
4. 考虑句子所表达的逻辑关系来选择
The year when he graduated from college was 2010.
=The year in which he graduated from college was 2010.
“be born” 通常搭配 “in”,表示 “在某个城市出生”
这里表示 “在某一年”,用 “in” 符合时间上的逻辑关系
介词的选择
5. 表示“所有”或“整体的一部分”时通常用both/none/some/most...+介词 “of ”+which/whom 翻译成:其中两个都,其中没有,其中一个,其中大部分等
He has two sons, _____________ graduated from Peking University.
他有两个儿子,他们都毕业于北京大学。
2) Tom wrote many children’s books, half __________ were about campus culture.
汤姆写了很多儿童书籍,其中一半是关于校园文化的。
both of whom
of which
介词的选择
关系代词or关系副词?
This is the reason _____________ I didn't come.
why/for which
指时间,地点或原因的先行词在定语从句中作状语时,用关系副词。
指时间,地点或原因的先行词在定语从句中作主语或宾语时,用关系代词。
The reason ___________ she gave was not true.
which/that
判断依据:先行词在从句中所作成分
① 从句缺少主、宾、定
② 从句缺状语
关系代词
关系副词
Read the passage and underline the words that where, when and why refer to.
In April 2017, two giant pandas from China arrived at a zoo in the Netherlands. There, they were welcomed to the Chinese-style compound where they were to live. On 30 May, after the preparations were complete, the day finally came when the pandas met their fans for the first time. People were excited – the zoo is the only place in the country where it is possible to see pandas. In fact, the last time there were pandas in the Netherlands was in 1987. And of course, the main reason why they were so excited is that pandas are just so cute!

Look at the pictures and complete the idioms with animal names.

cats
Complete the paragraph with the animal idioms in Activity 4.
English idioms are a way of adding colour to the language. For example, instead of saying “It’s raining heavily”, you could say “1_________________________”. Another reason to use idioms is that they are concise. For example, to describe someone who is always working or busy doing something, we can say they are 2________________. If they’re rushing into something and should wait and be patient, you could say “3__________________”. Learning idioms can be fun, especially when we compare them to Chinese equivalents. Take, for example, “4___________________________________” (people do what they want and have fun when someone in authority is absent) and “5____________________________” (solve two problems with one action) – are there corresponding idioms in Chinese
It’s raining cats and dogs
as busy as a bee
hold your horses
When the cat’s away, the mice will play
kill two birds with one stone
Work in pairs. Find more animal idioms. Choose an idiom and describe a situation with it.
put the cart before the horse 本末倒置
lock the stable door after the horse has been stolen 亡羊补牢
birds of a feather flock together 物以类聚
look a gift horse in the mouth 吹毛求疵
ride the high horse 趾高气扬
let sleeping dogs lie 莫惹是非
a black sheep 害群之马
She’s as busy as a bee.

Transcript
DJ: Joining us today we have zookeeper Max Wilson, and Amy Lee from the organisation Keep Wild Animals Wild. They are here to discuss whether we should keep wildanimals in zoos, Max, let's start with you.
Max: As a zookeeper, I’ve seen how zoos help protect animals in danger of dying out. For example, my zoo is well-known for its programme to save tigers.
Amy: I’m afraid I don’t agree that these programmes are always successful. We’ve seen a lot of examples where the animals start to depend too much on humans, and are unableto live on their own when returned to the wild. We’ve seen a lot of examples that have failed.
Max: But you must admit there are successful ones. And zoos are also a good way to educate people about animals. That’s killing two birds with one stone.
Transcript
Amy: Oh, I totally agree that people should learn as much as possible about animals because we share the planet with them.
Max: Exactly. Zoos allow us to observe animals in places that are similar to their natural environments.
Amy: I’m sorry, but that’s just not true. No zoo can offer its animals an environment that’s as good as their natural one. Elephants, for example, need a huge amount of space to live happily. On the whole, I think zoos do more good for people than for animals.
DJ: Well, I think we all agree that we should do our best to help protect animals and teach people more about them, Let’s continue this discussion after a short break.
Work in pairs. Hold a debate on whether we should keep animals as pets.
Student A: Turn to Page 107.
You are in favour of keeping animals as pets. You have the following arguments:
Keeping pets develops a kind and caring attitude towards animals.

Student B: Turn to Page 110.
You are against keeping animals as pets. You have the following arguments:
Caring for other people is more important than caring for animals.
It is bad for animals’ physical and mental health to be kept as pets.
Animals kept at home can cause trouble for neighbours.
Work in pairs. Think of another topic that is related to animals and hold a debate.
