Part 4 You will hear part of a biology lecture about dolphins and how views divide over their level of intelligence.
2
First, you have some time to look at questions 31 to 40.
3
Thank you.
4
Now listen carefully and answer questions 31 to 40.
5
In today's lecture, we'll dive into the topic of dolphin intelligence,
6
discussing dolphin behavior and their physical structure,
7
in an attempt to shed light on the question, how intelligent are dolphins?
8
Well, concerning body size, dolphin brains are among the largest in the animal kingdom,
9
more extensive than chimpanzees.
10
And certain species, like bottlenose dolphins,
11
have brains even bigger than humans.
12
However, some current tests suggest that they do not possess the same cognitive abilities as humans,
13
despite having a similar brain size.
14
For instance, dolphins are often trapped in gill nets,
15
originally intended for tuna fishing.
16
These entanglement cases have led to unnecessary injury or deaths of dolphins,
17
gradually depleting their numbers.
18
Clearly, dolphins don't realize that they could just jump over these vertical barriers and swim to safety.
19
People often mistakenly view dolphins' eternal smile as signs of intelligence and joy.
20
Actually, this is not a facial expression at all,
21
but a fixed design of their head.
22
Unlike human beings with greater than 40 facial muscles,
23
dolphins have no such powers with which to form an expression.
24
On the other hand, small-brained animals are sometimes underrated for their level of intelligence.
25
Pigeons and rats are typical examples of small-brained animals,
26
which can perform tasks so complex that most humans would have trouble with them.
27
Over the last few decades,
28
scientists have conducted countless studies on the cognitive abilities of these overlooked animals,
29
with quite surprising results.
30
Pigeons are aware of their bodies when they see their reflections in the mirror.
31
Pigeons are also trained under specific conditions and gradually form instinctive reactions.
32
In an experiment in 2009,
33
a group of 12 pigeons was given a reward,
34
like food and water, every time they pecked a key on a lab table.
35
All birds successfully performed the trick.
36
These test results indicate that brain size is probably not the sole factor in determining intelligence.
37
Another argument steers the attention,
38
to the correlation between intelligence
39
and the constituents of brains rather than their sheer sizes it's been found
40
that dolphin brains are comprised chiefly of fatty cells
41
which serve as a protective barrier between the systemic blood
42
and the extracellular environment of the central nervous system they are also essential components of nerve cell membranes,
43
affecting problem-solving skills performance.
44
Now, the second mainstream view,
45
is that dolphins are highly intelligent.
46
Research into the behavior of dolphins in the wild,
47
and in captivity, has yielded incredible data,
48
on the intelligence of these marine mammals.
49
Studies show that dolphins not only have the ability to learn as individuals,
50
but those individuals can then pass their new knowledge on to others.
51
Let's take a look at some typical examples.
52
Among these are tested with Billy,
53
a dolphin trapped in a sea lock and rescued.
54
Billy spent three weeks in rehabilitation and was released back into the wild.
55
There, researchers noticed that Billy had started tailwalking,
56
a skill only mastered by captive dolphins who imitated the keepers.
57
Billy had not been trained to tailwalk,
58
but had learned the skill simply by observing other dolphins in the rehab center.
59
Another study involves a female dolphin named Karen.
60
Karen was given a test,
61
in which she was rewarded with a fish,
62
for every piece of litter she brought to researchers.
63
To maximize its bounty, she quickly learned to take a newspaper,
64
keep it at the bottom of a tank,
65
and tear off smaller pieces to get more fish.
66
Over the past hundred years,
67
researchers have proven that dolphins are extremely social species,
68
and have evolved to have highly developed brains.
69
These factors are the most significant contributors to their intelligence,
70
and become the means of survival for dolphins.
71
In 2008, researchers tracked a group of around 400 dolphins.
72
One female dolphin in the group was having a lot of trouble swimming,
73
and kept flipping upside down,
74
or sinking into the water.
75
The other dolphins crowded around it.
76
They paddled side by side with the injured female on their backs.
77
By keeping the wounded female above water,
78
they may have helped it to breathe, avoiding drowning.
79
So how do they communicate with each other?
80
Well, scientists have discovered, through observation and meticulous testing,
81
that every dolphin has a different sound,
82
resembling the whistle that other dolphins recognize as a particular individual.
83
Dolphins can emit a wide variety of sounds.
84
The frequency levels range ten times beyond what humans can hear.
85
But of course, there are other means of communication for dolphins, besides sound.
86
During mating season, male dolphins stroke females with flippers,
87
after a fight to affirm social bonds.
88
That is the end of part four.
89
You now have one minute to check your answers to part four.
90
Thank you.

왜 이 비디오로 말하기 연습을 해야 할까요?

이 비디오는 돌고래의 지능에 관한 생물학 강의를 담고 있습니다. 유튜브를 통한 영어 공부는 다양한 주제를 접할 수 있게 해 주며, 특히 해당 강의는 돌고래의 행동과 신체 구조에 대한 깊은 이해를 제공합니다. 영어 쉐도잉을 활용하여 이 비디오를 따라 말하면서, 귀하의 발음과 억양을 향상시킬 수 있습니다. 즉, 청취 능력을 기르는 동시에 자신감을 갖고 영어로 대화하는 연습을 할 수 있습니다. 강의를 통해 제공되는 복잡한 어휘와 문장을 사용함으로써, 글쓰기 및 말하기 능력을 더욱 끌어올릴 수 있는 기회를 제공합니다.

문맥 속의 문법과 표현

비디오 강의에서는 다음과 같은 중요한 문법 구조와 표현들이 사용되었습니다:

  • ‘concerned with’: 특정 주제에 대해 이야기할 때 흔히 사용됩니다. “오늘의 лекция는 돌고래의 지능에 대해 다룬다”와 같은 구문은 학문적인 문맥에서 자주 사용됩니다.
  • ‘suggest that’: 추측이나 의견을 제시할 때 유용한 표현입니다. 예를 들어, “현재의 시험들은 그들이 인간과 동일한 인지 능력을 가지지 않음을 시사한다”라는 문장을 통해 주장이나 의견을 나타낼 수 있습니다.
  • ‘so complex that’: 결과에 대한 설명을 할 때 자주 활용되는 표현입니다. “이 새들은 복잡한 작업을 수행할 수 있다”는 문장에서 사용됩니다.

이러한 표현들을 실제 대화 속에서 활용하면 자신감 있는 의사소통을 도와줄 것입니다. 영어 쉐도잉 연습을 통해 이 문법 구조를 자연스럽게 사용할 수 있게 될 것입니다.

일반적인 발음 트랩

비디오에서 다루어진 특정 단어들은 발음에 어려움을 줄 수 있습니다. 특히 ‘cognitive’라는 단어는 많은 학습자들에게 도전이 될 수 있으며, 이 단어는 /ˈkɒɡ.nɪ.tɪv/와 같이 발음됩니다. 이외에도 ‘species’와 같은 단어는 ‘스피시스’라고 잘못 발음하기 쉬우니 주의가 필요합니다. 이러한 단어들은 영어 쉐도잉을 통해 반복 연습함으로써 발음을 개선할 수 있습니다. 지속적인 연습을 통해 자연스럽게 영어 발음에 익숙해질 수 있습니다. 유튜브 영어 공부에서 제공되는 다양한 자료를 활용하여, 보다 정확한 발음과 억양을 익혀보세요. shadow speech 기술을 통해 더욱 유창하게 대화하는 능력을 향상시키실 수 있습니다.

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.
