쉐도잉 연습: How Your Dog Can Protect You Before You're Born - 영상으로 영어 말하기 배우기

Mmm, puppies.

Most dog owners say companionship is the number one reason to have a cuddly, devoted tail wager, and some people also have dogs for assistance or protection.

And just look at them!

They're so cute!

So it's not surprising that we're willing to put up with less savory features of dogs, like muddy paw prints and slobber all over everything.

Yet slobber and other pet dirt may actually be a pet benefit too, especially if you happen to be an unborn baby.

This, and also cats, influence the microbial communities in our homes

so much that if your mother lives with a cat or dog while she's pregnant with you, you're about 30% less likely to suffer from allergies as a child.

This sounds kind of crazy, and we don't know exactly why it happens, but the most likely explanation is called the hygiene hypothesis.

You know how children from Amish farm families have been found to suffer less from allergies

and asthma than is typical in the modern westernized world?

Well, scientists think it's because their immune systems develop more fully, thanks to exposure to a wide variety of dirt, bacteria, and germs in fermenting feed,

cow manure, and other barnyard delights.

A key part of your immune system is the cells that recognize and neutralize foreign bacteria, viruses, transplanted body parts, or even your own damaged cells.

Healthy cells in your body have distinctive proteins on them that immune cells recognize as part of you, while intruders and unhealthy cells without you proteins are flagged for careful monitoring.

If any not-you stuff starts causing too much harm, your immune cells will attack it and take note to act quickly and vigorously against it in the future,

basically learning who's harmlessly passing through and who's a dangerous intruder.

But if the immune system incorrectly identifies an intruder or doesn't properly learn who's who in the first place, our bodies can overreact to harmless substances,

like a life-threatening allergic reaction to a minor bee sting.

In the Western world, the percentage of children who suffer from immune system over reactions like allergies

and asthma has roughly doubled in the past 40 years or so, even as infectious diseases have become much less common thanks to improved hygiene, water and sewage treatment, and so on.

It's highly likely that the increased prevalence of allergies

and asthma is due in part to the fact

that the environments we live in are too clean

and don't give our immune system proper opportunity to learn who's who at a young age.

Kind of like how we're better at learning foreign languages when we're younger, our Your immune systems are best at learning to distinguish harmless foreign substances from harmful ones

when exposed to them very early in life.

That's why having dog slobber, kitty hairballs, and muddy paw prints around your mother

while you're in utero might get your immune system off to a proper start even before you're born.

We still don't know exactly how your mother's exposure to extra bacteria influences you in the womb, but we do know that having a pet around before

and after your birth may help keep your immune cells from barking up the wrong tree.

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.
