Talking About Mysteries The Unknown in English Spoken English Lesson

Hi, I’m Molly. Welcome to Oxford Online 
English! In this lesson, you can learn to  

talk about mysteries and things we can’t explain.
Do you like a good mystery? Perhaps you read a  

book, saw a film, or watched a documentary 
about something which can’t be explained? 

Think about the last mystery that had 
you wondering…what happened there?! 

In this lesson, you’ll learn about describing,  

responding to and speculating about mysteries. 
You’ll also hear about some interesting ones. 

Also, do you want English subtitles 
while watching this video?  

Click the ‘CC’ button in the bottom right now 
to turn on English subtitles if you need them. 

Now, let’s look at useful language that will 
help you talk about exciting mysteries. 

Ever heard of Dan Cooper? An unknown criminal who hijacked an airplane in the 70s? 

No, never heard of him.
I just watched a fascinating documentary  

about him on YouTube. His crime is still one of 
the greatest unsolved mysteries in US history! 

Okay, so what happened?
Well, the story of Dan Cooper is an intriguing  

one. So this guy, Dan Cooper, hijacked a plane 
full of passengers flying over the U.S. No one  

knows who he was and the case has baffled the FBI 
for over 50 years. Why did he do it? Terrorism? 

For money! During the flight, Cooper said he had a 
bomb in his briefcase and demanded parachutes and  

$200,000. The plane landed in Seattle and the 
passengers were exchanged for the money. Now,  

this is where the story gets really interesting!
Go on. 

The plane took off again for Mexico with 
instructions from Cooper to fly at 10,000 feet.  

At some point during the flight, they think 
Cooper jumped out of the plane with all the cash. 

Okay, so this guy escaped with the money?!
Well, that’s still unexplained. There are  

theories about what happened to him but 
the case remains a mystery to this day. 

So that’s it? They must know 
more about what happened? 

Well…
You’ll hear more about  

what happened to Dan Cooper later, in part three 
of the lesson. But now, let’s look at the useful  

language you heard to describe the mystery.
A great way to introduce a mystery you want  

to talk about is to say: ‘Ever heard 
of…?’ or ‘Have you heard about…?’ 

These mean you’re going to tell 
the listener something of interest. 

When you introduce a mystery, you might also 
use phrases like ‘no one knows’ or ‘no one  

knows for sure’. For example: ‘no one knows 
for sure who Jack the Ripper really was.’ 

‘No one knows where Cleopatra’s tomb is.’ 

Can you think of anything else 
‘no one knows’ the answer to? 

Next, you heard some adjectives beginning 
with U-N in the conversation which described  

the mystery of Dan Cooper.
Can you remember them?  

There were three; what were they? 

You heard ‘unknown’, ‘unsolved’ and 
‘unexplained’. You can use these words  

to talk about situations we can’t explain.
One of these words is commonly used together  

with the word ‘mystery’ to make a 
collocation. Do you know which one? 

‘Unsolved mystery’ is a common 
collocation. For example,  

the Dan Cooper incident is an ‘unsolved mystery’, 
because we still don’t know what happened. 

Correct use of collocations is a great 
way to expand your communication skills  

and express yourself more clearly. There are 
other useful collocations with the word ‘mystery’. 

For example, to describe a situation where 
there are unexplainable elements, you can say:  

‘There is an air of mystery to it’, or, 
‘The situation is shrouded in mystery’. 

If a mystery has been solved, then you 
can say the mystery has been ‘cleared up’. 

If it looks like the mystery will stay unsolved, 
you can say it will ‘remain a mystery’. 

Let’s look at other adjectives 
from the conversation. 

‘Fascinating’ means that something 
is extremely interesting.  

What was the last unsolved mystery 
you thought was fascinating? 

‘Intriguing’ has a similar meaning to 
‘fascinating’; if something is intriguing,  

it’s interesting and it makes you feel 
curious. You want to know more about it. 

‘Mysterious’ describes something you find hard to 
explain. You can use it with many different words:  

a mysterious noise, a mysterious stranger, 
a mysterious disappearance, and so on. 

Finally, you heard the speaker say:
‘The case has baffled the FBI for 50 years’. 

‘Baffled’ means extremely 
confused about something. 

Got it? Don’t forget that you 
can review any part of the lesson  

which you find difficult! Let’s 
move on to our next mystery. 

Have you heard of the Mary 
Celeste? The ghost ship? 

Ghost ship? No. What is that?
It was a ship, found drifting in the  

middle of the Atlantic Ocean, totally empty.
Sounds interesting! Tell me more! 

Well, this has baffled historians for over a 
hundred years. The ship left New York in December  

1872, sailing for Italy. They found it 
a month later with all the crew missing! 

Hmmm… Okay, so something happened on 
board, and everyone abandoned the ship? 

Well, it’s not that straightforward. When they 
found the ship, there was nothing wrong with it.  

What’s more, there were plenty of supplies and 
all the crew’s possessions were still on board. 

How could that be?
No one knows for sure,  

but there are some interesting theories 
as to what might have happened. 

Such as?
Some people believe  

pirates killed the crew. Others suspect that 
two of the crewmen killed the rest of the crew  

because their possessions weren’t found.
The passengers were murdered?  

This is giving me the creeps.
Other theories suggest mother nature, a storm  

maybe, caused the crew to abandon ship, but that 
doesn’t explain why they left everything behind. 

Yeah, that’s so weird.
Some people believe there  

must be a supernatural explanation, and 
the crew were taken by aliens, ghosts  

or some other type of creature from the deep!
Creatures from the deep? Surely not!  

Anyway, I’ve heard enough. Monsters 
from the ocean freak me out. 

A great way to show interest in a mystery 
story is to tell the person you’re interested.  

Can you remember how I did this? 

Look at some phrases you 
heard. Can you complete them? 

Pause the video and think about your answers. 
If you want, you can also go back, listen to the  

dialogue again, and find the missing words.
Did you get all four? Let’s check. 

The listener also responded to 
‘pirates killed the crew’ and ‘crewmen  

killed the crew’ by echoing this with a 
question: the passengers were murdered? 

These phrases show the speaker that you are 
listening and interested in what they are saying. 

Let’s do some practice. We’re going 
to use the conversation from part one.  

If you haven’t watched part one, that’s 
okay. You can still complete this task. 

Imagine: someone is telling 
you a story about a mystery. 

See if you can respond show more interest 
using the language you’ve just seen. 

Read and repeat the responses that you see on 
the screen. Then, to make it more difficult  

for yourself, you can rewind, close your 
eyes, and try and respond without looking. 

Ready? Here we go. 

His crime is still one of the greatest 
unexplained mysteries in US history. 

The case has baffled the FBI for over 50 years! 

They think Cooper parachuted out 
of the plane with all the cash. 

Nice job! Now try it again but this time 
don’t read the responses. Also: focus on your  

intonation. Intonation is essential to express 
interest. If you say ‘Really. I’m intrigued now’,  

you won’t sound interested. You need 
intonation: ‘Really? I’m intrigued now!’ 

Learning how to respond to 
mysteries and stories with interest  

will help you in your everyday conversations too. 

Next, you will learn how to speculate about 
a mystery. You speculate when you talk about  

something you don’t know about; maybe you have an 
idea, or you just want to guess about what happened. 

Using past modal verbs is a good way to do 
this: you can use the modal verbs ‘must’,  

‘might’, ‘may’, ‘could’ and ‘can’t’ 
to speculate about the past. 

So, let’s go back to the story 
about the mysterious Dan Cooper. 

While you listen to this conversation,  

think about these two things. 
What are the speakers sure about? 

And, what are the speakers unsure about?
Got it? Let’s listen. 

They must know more about what happened?
Well… for starters, they know so little  

about the man that Dan Cooper 
might not ‘ve been his real name 

Okay. So did they figure anything out?
So many things are uncertain.  

As the plane was flying over the Washington 
mountains at night, he probably parachuted  

out. They’re not completely sure.
You mean he could’ve hidden 

on the plane and escaped later?
Possibly, but police searched the  

plane and didn’t find him.
So he must’ve jumped out! 

But he can’t’ve survived the jump from 10,000 
feet into the mountains! Did they find his body? 

No body or parachute was ever found. They did find 
a bag containing $6000 in a river. It may have  

belonged to Cooper but even that wasn’t certain.
Wow. Great story! I wonder what really happened  

to him? Maybe he’s sitting on a beach in 
Mexico right now laughing at all of us? 

Haha…maybe.
So, the speakers gave their  

ideas about what happened to Dan Cooper. What were 
they sure about and what were they unsure about? 

If you are unsure yourself, go back 
and listen to the conversation again. 

Firstly, let’s look at the 
things they were sure about  

and how they used past modals to communicate that. 

Can you fill in the blanks 
with the modal verbs you heard? 

He must have jumped out! 

This means the speaker is certain that 
Cooper did jump out of the airplane. 

He can’t have survived the jump. 

This means the speaker is certain 
that Cooper didn’t survive the jump. 

Why is the speaker so sure Cooper 
jumped out of the airplane? 

Because the police didn’t find 
Cooper when they searched the plane. 

Why is the speaker so sure that 
Cooper can’t have survived the jump? 

Because the speaker assumes it’s impossible 
to survive a jump into the mountains. 

You can use ‘must have’ or ‘can’t have’ to talk 
about things in the past where you don’t know  

for a fact, but you’re sure about what happened. 
You use logical deduction to reach a conclusion. 

Now, let’s look at the things the 
speakers were unsure about. They said:  

Dan Cooper might not have been his real name. 

He could’ve hidden on the plane.
It may have belonged to Cooper. 

The speakers in these cases are not sure. You 
can use ‘might have’ ‘could have’ or ‘may have’  

to talk about something in the past which 
you think is possible, but you’re not sure. 

So, if you say ‘He could have hidden on 
the plane’, you mean that it’s possible,  

but not certain, and either way you don’t know.
What do you think happened to Dan Cooper?  

Pause the video and make two sentences you are 
sure of and two sentences you are unsure of. 

Now, listen to me say these sentences again 
and repeat after me. He must’ve jumped out. 

He could’ve hidden on the plane.
Which words are stressed? And, which sounds  

are missing? Listen more than once if you need to.
The modal verbs ‘must’ and ‘could’ are stressed. 

For past modals of deduction, the 
modal verb is usually stressed.  

This is because the speaker wants to 
emphasize their logical conclusion or guess. 

The missing sound was the ‘h’ sound in have. 

The ‘have’ is pronounced in its weak 
form so you shouldn’t make the ‘h’ sound. 

What do you think happened to Dan Cooper or 
the Mary Celeste? Comment below and tell us  

what you think happened in these famous unsolved 
mysteries. Use the language you learned today. 

Thanks for watching!
See you next time!

嗨,我是莫莉。 欢迎来到牛津在线
英语! 在本课中,您可以学习

谈论我们无法解释的奥秘和事物。
你喜欢一个好的谜吗? 也许您读过一

本书、看过一部电影或看过一部
关于无法解释的事情的纪录片?

想想让你想知道的最后一个谜团
……那里发生了什么?!

在本课中,您将学习如何描述、

回应和推测谜团。
您还会听到一些有趣的消息。

另外,您
在观看此视频时想要英文字幕吗? 如果需要,请

点击右下角的“CC”按钮
打开英文字幕。

现在,让我们看看有用的语言,它们可以
帮助您谈论令人兴奋的奥秘。

听说过丹·库珀吗? 一个在 70 年代劫持飞机的不知名罪犯?

不,从来没有听说过他。
我刚刚在 YouTube 上观看了一部关于他的精彩纪录片

。 他的罪行仍然是
美国历史上最大的未解之谜之一!

好吧,那发生了什么?
嗯,丹·库珀的故事很

有趣。 所以这个人,丹·库珀,劫持了一架
满载乘客的飞机飞越美国。没人

知道他是谁,这个案子让联邦调查局困惑
了 50 多年。 他为什么这样做? 恐怖主义?

为了钱! 在飞行过程中,库珀说
他的公文包里有一枚炸弹,并要求提供降落伞和

200,000 美元。 飞机降落在西雅图,
乘客们被兑换了钱。 现在,

这就是故事变得非常有趣的地方!
继续。

飞机在库珀的指示下再次起飞前往墨西哥,
飞行高度为 10,000 英尺。

在飞行过程中的某个时刻,他们认为
库珀带着所有现金跳下飞机。

好吧,所以这家伙带着钱逃走了?!
好吧,这仍然无法解释。

关于他身上发生的事情有各种说法,
但此案至今仍是个谜。

就是这样了? 他们必须
更多地了解发生了什么?

嗯……
您将

在本课的第三部分稍后听到更多有关 Dan Cooper 发生的事情
的信息。 但是现在,让我们看看

你听到的描述这个谜团的有用语言。
介绍您想谈论的谜题的一个好方法

是说:“听说
过…?”或“您听说过…?”

这意味着您要
告诉听众一些有趣的事情。

当你介绍一个谜时,你可能还会
使用“没人知道”或“没人肯定知道”这样的短语

。 例如:“没有人
知道开膛手杰克到底是谁。”

“没有人知道克利奥帕特拉的坟墓在哪里。”

你能想到其他
“没有人知道”的答案吗?

接下来,您
在描述丹·库珀之谜的对话中听到了一些以 U-N 开头的形容词


你能记住他们吗?

有三个; 他们是什么?

你听到了“未知”、“未解决”和
“无法解释”。 您可以使用这些词

来谈论我们无法解释的情况。
其中一个词通常

与“神秘”一词一起使用以进行
搭配。 你知道是哪一个吗?

“未解之谜”是一种常见的
搭配。 例如

,丹·库珀事件是一个“未解之谜”,
因为我们仍然不知道发生了什么。

正确使用搭配
是扩展您的沟通技巧

并更清晰地表达自己的好方法。
“神秘”一词还有其他有用的搭配。

例如,要描述
存在无法解释的因素的情况,您可以说:

“有一种神秘的气氛”,或者,
“情况笼罩在神秘之中”。

如果一个谜已经解开了,那么你
可以说这个谜已经“澄清”了。

如果看起来这个谜团仍未解开,
您可以说它“仍然是个谜”。

让我们看看对话中的其他
形容词。

“引人入胜”意味着某事
非常有趣。

您认为令人着迷的最后一个未解之谜
是什么?

“Intriguing”与“着迷”具有相似的含义
; 如果某件事很有趣,

那就是有趣,它会让你感到
好奇。 你想了解更多。

“神秘”描述了您发现难以
解释的事物。 您可以将它与许多不同的词一起使用

:神秘的噪音、神秘的陌生人
、神秘的失踪等等。

最后,你听到演讲者说:
“这个案子让 FBI 困惑了 50 年”。

“困惑”意味着
对某事感到非常困惑。

知道了? 不要忘记,您
可以复习课程

中您觉得困难的任何部分! 让我们
继续我们的下一个谜团。

你听说过玛丽·
塞莱斯特吗? 幽灵船?

幽灵船? 不,那是什么?
那是一艘在大西洋中部漂流的船

,完全空无一人。
听起来不错! 告诉我更多!

一百多年来,这一直困扰着历史学家
。 这艘船于 1872 年 12 月离开纽约

,驶往意大利。
一个月后,他们发现所有船员都失踪了!

嗯……好吧,船上发生了什么事
,所有人都弃船了?

好吧,这不是那么简单。 当他们
找到这艘船时,它没有任何问题。

更重要的是,有充足的补给,
所有船员的财物都还在船上。

怎么可能?
没有人确切知道,

但是对于可能发生的事情有一些有趣的理论

如?
有些人认为

海盗杀死了船员。 其他人则怀疑其中
两名船员杀死了其余的船员,

因为他们的财物没有被发现。
乘客被杀?

这让我毛骨悚然。
其他理论认为大自然母亲,也许是一场风暴

,导致船员弃船,但这
并不能解释为什么他们把一切都抛在脑后。

是的,这太奇怪了。
有些人认为

一定有超自然的解释
,船员是被外星人、鬼魂

或其他类型的深海生物带走的!
来自深渊的生物? 肯定不是!

不管怎样,我已经听够了。
来自海洋的怪物吓坏了我。

对神秘故事表现出兴趣的一个好方法
是告诉你感兴趣的人。

你还记得我是怎么做到的吗?

看看你
听到的一些短语。 你能完成它们吗?

暂停视频并思考你的答案。
如果你愿意,你也可以回去,再听

一遍对话,然后找到缺失的单词。
四个都拿到了吗? 让我们检查。

听众还回应了
“海盗杀死了船员”和“船员

杀死了船员”的
问题:乘客被谋杀了?

这些短语向说话者表明您正在
倾听并对他们所说的内容感兴趣。

让我们做一些练习。 我们
将使用第一部分的对话。

如果你还没有看过第一部分,那
没关系。 您仍然可以完成此任务。

想象一下:有人在
给你讲一个关于一个谜的故事。

看看你是否可以用你刚刚看到的语言回应,表现出更多的兴趣

阅读并重复您在屏幕上看到的回复
。 然后,为了

让你自己更难,你可以倒带,
闭上眼睛,试着不看就做出回应。

准备好? 开始了。

他的罪行仍然是
美国历史上最大的未解之谜之一。

这个案子让联邦调查局困惑了50多年!

他们认为库珀
带着所有的现金跳伞下了飞机。

不错的工作! 现在再试一次,但这次
不要阅读回复。 另外:专注于你的

语调。 语调对于表达
兴趣至关重要。 如果你说‘真的。 我现在很感兴趣”,

你听起来不会感兴趣。 你需要
语调:“真的吗? 我现在很感兴趣!

学习如何对
谜团和故事做出有趣的回应

也将有助于您的日常对话。

接下来,您将学习如何
推测谜团。 当你谈论

一些你不知道的事情时,你会猜测; 也许你有一个
想法,或者你只是想猜测发生了什么。

使用过去的情态动词是一个很好的
方法:你可以使用情态动词“必须”、

“可能”、“可能”、“可以”和“不能”
来推测过去。

那么,让我们回到
神秘的丹·库珀的故事。

在您聆听此对话时,请

考虑这两件事。
演讲者确定什么?

而且,演讲者不确定什么?
知道了? 让我们听听。

他们必须知道更多关于发生了什么?
嗯…对于初学者来说,他们

对这个人知之甚少,以至于丹·库珀
可能不是是他的真名

。好吧。 那么他们有什么发现吗?
很多事情都是不确定的。

当飞机晚上飞越华盛顿
山脉时,他可能跳伞

了。 他们并不完全确定。
你的意思是他可以

在飞机上然后逃跑?
可能,但警察搜查了

飞机并没有找到他。
所以他一定已经跳出来了!

但他不能从 10,000
英尺高处跳入山中! 他们找到他的尸体了吗?

没有发现尸体或降落伞。 他们确实
在河里发现了一个装有 6000 美元的袋子。 它可能

属于库珀,但即便如此也不确定。
哇。 很棒的故事! 我想知道他到底发生

了什么? 也许他现在正坐在墨西哥的海滩上
嘲笑我们所有人?

哈哈……也许吧。
因此,演讲者

就丹·库珀身上发生的事情发表了自己的看法。
他们确定什么,不确定什么?

如果您不确定自己,请返回
并再次聆听对话。

首先,让我们看看
他们确定的事情

,以及他们如何使用过去的模态来传达这一点。

你能用
你听到的情态动词填空吗?

一定跳了出来!

这意味着演讲者确信
库珀确实跳出了飞机。

不可能在跳跃中幸存下来。

这意味着演讲者
确信库珀没有在跳跃中幸存下来。

为什么演讲者如此肯定库珀
从飞机上跳了下来?

因为警察
在搜查飞机时没有找到库珀。

为什么演讲者如此确定
库珀无法幸免于难?

因为演讲者认为
跳入山中是不可能的。

您可以使用“必须拥有”或“不能拥有”来
谈论过去您不

知道事实的事情,但您可以确定发生了什么。
您使用逻辑推理得出结论。

现在,让我们看看
演讲者不确定的事情。 他们说:

Dan Cooper 可能不是是他的真名。

本可以藏在飞机上。
可能属于库珀。

这些情况下的发言者并不确定。 您
可以使用“可能有”、“可能有”或“可能有”

来谈论
您认为可能但不确定的过去某事。

所以,如果你说“他可能藏
在飞机上”,你的意思是有可能,

但不确定,无论哪种方式你都不知道。
认为丹·库珀发生了什么?

暂停视频并说出两句你
确定的句子和两句你不确定的句子。

现在,听我再说一遍这些句子,
然后跟着我重复。 他一定是跳出来了。

他本可以躲在飞机上的。
哪些词是重音? 而且,

缺少哪些声音? 如果需要,请多听一次。
情态动词“必须”和“可以”被强调。

对于过去的演绎情态,情
态动词通常是重读的。

这是因为说话者想要
强调他们的逻辑结论或猜测。

缺少的声音是have中的“h”声音。

“have”的发音很弱,
所以你不应该发出“h”的声音。

您认为 Dan Cooper
或 Mary Celeste 发生了什么? 在下方发表评论,告诉

我们您认为在这些著名的未解
之谜中发生了什么。 使用你今天学到的语言。

感谢收看!
下次见!
