쉐도잉 연습: Science experiment for Year 12 students: Đề thi IELTS LISTENING (actual test) - 영상으로 영어 말하기 배우기

Part 3 You will hear a trainee science teacher called Claire talking about her practical teaching work to another trainee called Jake.

First, you have some time to look at questions 21 to 25.

Thank you.

questions 21 to 25.

Hi, Jake.

How are you getting on with the practical teaching?

It's harder than I expected, but I've got some great classes.

How about you?

Not brilliant.

I'm really struggling with my Year 12 science class.

Are they hard to control?

Well, I don't have discipline problems as such.

It's just that they don't seem to think

that science has anything to do with their lives it's depressing they listen to what i say

and i gave them a test last week and the results weren't too bad but there's no real engagement right

and as part of my teaching practice i have to design

an experiment for them to do i was wondering about something

on the children's diets you know asking them to record what they eat and maybe linking it to their state of health?

Hmm, let's think.

So your methodology would involve the children recording what they eat,

okay, but you'd also need to have access to the children's medical records, and I don't think people would be happy about that.

Confidentiality would be an issue.

If you could get the right data, the conclusions might be significant, but I suspect it's not going to be easy.

Right.

Have you thought about doing an experiment using animals?

Wouldn't that be upsetting for the children?

Well, the animals don't have to be harmed in any way.

It could just be an experiment where they're given a certain diet and the effects are observed.

Would I have to get permission to use these animals?

Yes.

You'd have to submit an outline of the experiment and fill in a form, but it's quite straightforward.

But if we found out that, say, a particular diet affects the health of animals, the same thing wouldn't necessarily be true for people, would it?

No, that's true.

But the findings for any experiment are going to be limited.

It's inevitable.

I suppose so.

So what animals could I use to investigate the effects of diet?

Mice?

Yes.

You'd need experimental mice, ones that have been specially bred for experiments.

OK, so what will your experiment be investigating exactly?

Well, something to do with nutrition.

So maybe we could look at food supplements, things like extra iron and extra protein and their impact on health.

That might be rather broad.

Maybe just look at the effects of one supplement, like sugar, on the health of the mice.

In fact, maybe the focus could be on whether mice can control their own diet.

So what happens when they have access to more sugar that they don't really need?

Exactly.

Do they eat it or do they decide to leave it?

Great.

Then later on you could do a follow-up experiment adding another variable.

Like you could give some of the mice the chance to be more active, running on a wheel or something, and the others just sit around and don't do much.

Or I could repeat the experiment, but change the type of food I provided, or use mice with a different genetic structure.

But I think your idea would be more interesting.

I might think about that some more.

Before you hear the rest of the discussion, you have some time to look at questions 26 to 30.

Now listen and answer questions 26 to 30.

So, can I talk through a possible procedure for the experiment where mice are given a sugar supplement?

Sure.

I did a similar experiment in college, actually.

Great.

So, how many mice would I need?

I'd say about 12, and all young ones, not a mixture of old and young.

OK.

And I'd need two groups of equal sizes, so six in each group.

And how would I tell them apart?

I suppose I could put some sort of tag on one group or just mark them in some way.

You could use food colouring.

That wouldn't hurt them.

Perfect.

Then each group would go into a separate cage and one group, let's call them group A, would be the control group.

So they'd just have ordinary mouse food.

I suppose you can buy that?

Yes, it comes in dry pellets.

And the other group would have the same as the first group, but they'd also have the extra sugar.

Would you just give them straight sugar?

It might be better to give them something like cereal with it.

Hmm.

Then you'd need to weigh the mice, I should think, once a week.

And you'd need an electronic balance.

But we can't hold them on the balance, or it'd affect the reading.

Exactly.

so you need something called a weighing chamber to stop the mice from running away.

It sounds complicated but actually you can just use a plastic box with holes in the top.

OK.

So once we've measured the weight gain of each mouse we

can work out the average for each group as well as the standard deviation and then see where we go from there.

That sounds cool.

I think the students will enjoy it.

Yes.

One thing you must remember...

Thank you.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
