6 Minute English from bbclearningenglish.com Hello and welcome to 6 Minute English from BBC Learning English.
2
I'm Beth.
3
And I'm Neil.
4
Don't forget that you can find a transcript and a quiz for this episode on our website, bbclearningenglish.com.
5
Now, today, Neil, we're talking all about solving crime.
6
Do you think you'd be a good detective?
7
Actually, no, Beth, I think.
8
My brain's not very good with details.
9
Today, we'll be talking about how artificial intelligence might help detectives and the police investigate crimes.
10
But first, I have a question for you, Beth.
11
In the UK, lots of people enjoy watching fictional detectives on TV.
12
These programmes are called murder mysteries and tell the story of a detective solving a crime.
13
In 2020, a magazine called the Radio Times asked readers who their favourite TV detective was.
14
So who do you think was the most popular?
15
Was it A, Sherlock Holmes,
16
B, Hercule Poirot or C, Miss Marple?
17
Surely it's Sherlock Holmes.
18
Well, you sound very sure but I will reveal the answer at the end of the programme.
19
Now, when the police are investigating crimes in the real world,
20
their techniques are often quite different from what we see on television.
21
Yes, solving crimes involves collecting and reviewing lots of evidence,
22
like DNA, fingerprints or CCTV.
23
All of this work takes a lot of time.
24
So can AI help police speed up the work and even solve crimes?
25
That's the question listener Alistair had for the BBC Radio 4 programme The Artificial Human.
26
And host Alex Krotoski wanted to know more.
27
So Alistair, why are you asking this question?
28
Tell us a little bit about yourself and where you're coming from.
29
So, my name's Alistair and I'm a serving police officer.
30
My background is with investigation.
31
I'm looking at artificial intelligence and thinking,
32
what can it do for me?
33
Alex asks Alistair to explain where he's coming from.
34
This means explain his perspective or point of view.
35
In informal English, we'll often ask someone,
36
do you get where I'm coming from?
37
And we're asking whether they understand our opinion or perspective.
38
Alistair explains that he's interested in how artificial intelligence could help solve crimes
39
because he's a police officer with a background in investigations.
40
If you have a background in something,
41
it means most of your previous work or experience was related to something.
42
For example, I work as a producer at BBC Learning English now making programmes but my background is in classroom teaching.
43
Alistair talks about using artificial intelligence for training and asks,
44
what can it do for me?
45
This means, how can artificial intelligence help or improve something?
46
When a crime happens, police officers have to collect and review a lot of information to find evidence.
47
When you have a lot of information to review,
48
it can be difficult to know what's important and find patterns which might be relevant to the crime.
49
But Professor Ruth Morgan, an expert in crime and forensic science,
50
thinks AI could help speed up police work,
51
as she told BBC Radio 4's The Artificial Human.
52
I think we're seeing a renaissance in the pattern recognition forms of evidence,
53
so finger marks, footwear marks.
54
There's been lots of challenges with those forms of evidence over the last ten years,
55
probably, going a little bit out of favour.
56
And yet, what we're beginning to see now with AI is
57
that you can take a photo of a mark with your phone,
58
compare that mark to the database and get real-time insight.
59
Ruth says there's a renaissance in looking at patterns in evidence,
60
such as finger marks or footwear marks.
61
Renaissance means new interest or activity in a particular topic or area.
62
This kind of evidence went a little bit out of favour over recent years because of the excitement around DNA evidence.
63
If something is out of favour,
64
it's less popular or appealing.
65
But AI could mean that patterns in finger marks or footwear marks are useful in solving crimes again.
66
This is
67
because AI can be used to compare a picture of a mark with a database of pictures from other crimes
68
and get real-time insight.
69
The adjective real-time means the information is presented at the same time that it's happening.
70
Yes.
71
AI can compare lots of information very quickly,
72
which makes finding patterns in evidence much easier and more reliable.
73
There are some problems with using AI to solve crimes, though.
74
To find these patterns, lots of private information would need to be collected,
75
and police usually have to give clear reasons why they need access to certain information in their investigations.
76
It's unlikely an AI-powered robot would ever replace a detective any time soon.
77
Yes, and that reminds me of your question, Neil.
78
I said that Sherlock Holmes was maybe the most popular detective.
79
Was I right?
80
You were absolutely right.
81
And I think people should try the quiz on our website to find out how much they know as well.
82
It's at bbclearningenglish.com.
83
OK, let's recap the vocabulary we've learned,
84
starting with the expression where you're coming from,
85
which means your opinion or perspective on something.
86
Your background is the area that you have the most work experience in.
87
The question, what can this do for me,
88
means how can this help or improve things.
89
Renaissance means new interest or activity in something.
90
If something is out of favour,
91
it has become less popular or appealing.
92
And the adjective real-time means information is presented as it is happening.
93
Once again, our six minutes are up.

语法与表达在上下文中的运用
- 背景：background - 在对话中提到的“我有侦查的背景”，可以用于描述个人的经验或专业领域，帮助您在谈论个人经历时更好地表达。
- 解释：explain where you're coming from - 这个短语用来请求他人解释他们的观点，适合在日常对话中使用。
- 能做什么：what can it do for me - 这个句型用于提出问题以探讨某事物的实际应用，促进与他人的讨论。

常见的发音陷阱
在本视频中，您可能会遇到一些具有挑战性的单词和表达。例如，"artificial intelligence"的发音可能对初学者来说比较困难。确保您注意每个音节，并多加练习以提高英语发音。此外，"evidence"和"investigate"等词在快节奏的对话中很容易让人混淆。建议通过重复听和模仿来克服这些发音障碍，利用shadowing site的方法来帮助您改善口音。

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
