Could apples, berries and cacao improve our memory as we get older?
2
This is News Review from BBC Learning English.
3
I'm Neil.
4
And I'm Beth.

8
Now the story.
9
What you eat could improve your memory as you age.
10
That's according to new research in the US that found people with a diet rich in flavanols
11
may be less likely to lose their memory.
12
The substance is found in tea,
13
berries, apples and cacao, the seeds that chocolate is made from.
14
But while some scientists think eating more dark chocolate could help,
15
others say more research is needed.
16
You've been looking at the headlines, Beth.
17
What's the vocabulary?
18
We have keep something at bay, stave off and drive.
19
This is News Review from BBC Learning English.
20
Let's look at our first headline.
21
This is from the Mail Online.
22
Six squares of dark chocolate a day may keep the memory loss at bay.
23
So, this headline is suggesting that eating dark chocolate can help prevent you from losing your memory as you get older.
24
The expression we are looking at is keep something at bay.
25
It's quite a strange-sounding expression.
26
What does it mean?
27
Well, quite simply, it means to stop something bad or dangerous,
28
harmful from happening to you.
29
So, in this case, the harmful thing is memory loss.
30
We want to prevent memory loss,
31
so we want to keep it at bay.
32
Yes.
33
And this expression does have a wider use.
34
It's not only about memory loss.
35
No, it's not.
36
We can use it for lots of harmful things,
37
but it is often related to health.
38
So, for example, washing your hands can keep infections at bay,
39
or exercising can keep heart disease at bay.
40
Yes.
41
And take note, we can also use the word but hold instead of keep,
42
hold something at bay, it means exactly the same thing.
43
Let's look at that again.
44
Let's look at our next headline.
45
This is from The Guardian.
46
Tea, apples and berries could stave off age-related memory loss, study suggests.
47
Again, this headline is about preventing something bad from happening to us,
48
in this case memory loss.
49
The expression we're going to look at is stave off.
50
Now, that word stave, that's an old-fashioned sounding word for a long stick, isn't it?
51
It is, yeah.
52
And it might help you to think about that long stick to understand this expression.
53
So, Neil, imagine something is physically threatening you,
54
maybe a pack of wild dogs,
55
and you have a long stick.
56
What are you going to do with it?
57
Well, if a pack of wild dogs was attacking me,
58
I would use that long stick to protect myself.
59
Maybe I could wave it and the dogs would go away.
60
That's a strong mental image.
61
It might help you to remember the meaning of this phrasal verb,
62
but actually we don't usually use stave off in a literal sense anymore.
63
We don't, but it does have the same meaning.
64
It just means to prevent something bad from happening,
65
just like our first expression, keep something at bay.
66
And again, this is something we often use with health.
67
Some people say that drinking orange juice can stave off a cold.
68
but we can also use it to mean prevent other general negative things.
69
Yes.
70
And one more interesting thing to note.
71
Stave off is a phrasal verb,
72
and it's the kind of phrasal verb that you can split in the middle.
73
So, you can say, orange juice staves off colds,
74
or you can say, orange juice staves colds off.
75
Let's look at that again.
76
Let's look at our next headline.
77
This is from The Independent.
78
Diet low in flavanols may drive age-related memory loss, scientists claim.
79
So, this headline is looking at the same story,
80
but from the opposite angle.
81
It's saying that a diet low in flavanols – now,
82
that's that substance that you find in apples,
83
berries, tea and cacao – a diet low in that could cause memory loss.
84
And the word we're looking at is drive,
85
a familiar word used differently here.
86
Yes, but we're not talking about cars here.
87
So, drive actually has a wider meaning than the one we all know connected to cars and driving.
88
It can also mean to force something in a certain direction.
89
Yes.
90
So, when the headline says that a diet low in flavanols drives memory loss,
91
it means that that diet pushes in the direction of memory loss.
92
And in the same way,
93
when you drive a car,
94
actually what you're doing is just forcing it to go in a certain direction.
95
OK, let's look at that again.
96
We've had keep something at bay – prevent something bad affecting you.
97
Stave off – also prevent something bad affecting you.
98
And drive – force in a certain direction.
99
Did you know that exercise can also help our brains?

为什么要通过这个视频练习口语？
通过观看《饮食能否改善记忆？》这一视频，学习者可以在愉快的环境中提升他们的英语口语能力。每当我们谈论饮食与健康的关系时，这样的主题不仅引人入胜，还能激发我们对于健康生活方式的思考。通过跟随视频中的对话，您可以挑战自己的发音和流利度，这是一种有效的 shadow speech 练习方法。此外，借助视频中的真实对话，学习者能够更好地理解日常交流中使用的词汇和表达。在享受内容的同时，您将提高 雅思口语练习 的能力，让您的语言技能更加全面。
语法与表达在语境中的运用
在这个视频中，演讲者使用了几个关键的表达和语法结构，使得讨论更具生动性和信息量。以下是一些总结：
- keep something at bay: 这个短语意味着阻止某些不好的事情发生，比如记忆丧失。 在讨论健康和饮食时，这是一个非常实用的表达，可以用于说明如何采取措施来预防疾病。
- stave off: 这个短语用于表示通过某种方式阻止坏事发生。在视频中说到通过饮食来 stave off 记忆丧失，让人意识到饮食习惯的重要性。
- could: 使用「could」表达可能性，为论点带来了不确定性，且适合讨论研究结果，体现了科学探索的严谨性。
常见发音陷阱
视频中提到的一些单词和短语，对于学习者来说可能是发音的挑战。尤其是 flavanols 和 cacao，这两个词常常让人困惑。确保您清楚它们的音标和发音，有助于增强您的口语水平。另一个常见的发音问题是如何自然地说 dark chocolate，很多学习者在这类词组中容易出现连读或跳音的情况。在练习时，您可以尝试使用 看YouTube学英语 作为工具，进行 shadowspeak 练习，从而改善自己的发音及流利度。
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。
