Question 4.
2
You will hear part of a lecture about time measurement.
3
First, you have some time to look at questions 31 to 40.
4
Thank you.
5
Now, listen carefully and answer questions 31 to 40.
6
Good morning, everyone.
7
Today, I'm going to talk about the research project I've been involved in on time measurement.
8
Do you know how time is measured?
9
Consider how we measure length and how,
10
with time, we encounter a difficulty.
11
Before we could grasp it,
12
it would slip through our fingers.
13
In fact, as we can see,
14
we are forced to have the resource to measure something else.
15
The movement of something in space or a set of movements in space.
16
All the methods that have been employed so far really measure time by a motion in space.
17
The measurement of time is no easy matter,
18
a scientific unit only arrived at after much thought and reflection.
19
As the most primitive form of measurement,
20
the sun seems to be natural.
21
Ever since man first noticed the regular movements of the sun and stars,
22
we have wondered about the passage of time.
23
Prehistoric people first recorded time according to the sun's position.
24
To start off, let us take noon,
25
which is when the Sun is on the meridian at the highest point of its course across the heavens,
26
and when it casts the shortest shadow.
27
But this measurement, which was regarded as a major one in ancient times,
28
was less important than the natural events that occurred.
29
The earliest natural events that had been recognized were in the heavens,
30
but during the course of the year there were many other events that indicated significant changes in the environment.
31
Seasonal winds and rains, the flooding of rivers,
32
the flowering of trees and plants,
33
and the breeding cycles or migration of animals all led to natural divisions of the year,
34
and the further observation and local customs led to the recognition of the seasons.
35
Years later, precise measurements were invented
36
because the passage of time was extremely important for astronomers
37
and priests who were responsible for determining the exact hour for daily rituals and for important religious festivals.
38
Apart from the connection with religion,
39
accurate time measurement was also related to the government,
40
since they divided the day or the night into different periods in order to regulate work and various events.
41
For thousands of years, devices had been used to measure and keep track of time.
42
The current sexagesimal system of time measurement dates back to approximately 2000 BCE from the Sumerians.
43
It was found that the earliest ancient timekeepers were mainly invented and used in Mesopotamia,
44
where the water clock was introduced from,
45
as well as in North Africa,
46
especially in the area of ancient Egypt.
47
So, now I'd like to introduce you to some of the most well-known ancient timekeepers,
48
as well as the disadvantages of them,
49
for which they were replaced by various new forms of clocks that were used afterwards.
50
A sun dial is a device that tells the time of day by the apparent positioning of the sun in the sky.
51
In the narrowest sense of the word,
52
it consists of a flat plate and a nomon which casts a shadow onto the dial.
53
As the sun appears to move across the sky,
54
the shadow aligns with different hour lines marked on the dial to indicate the time of day.
55
However, it was quickly noted that the length of the day varied at different times of the year,
56
therefore there could have been a difference between clock time and sundial time.
57
In addition, the sundial was of no use at night,
58
so a water clock was invented.
59
The water clock, or clepsydra,
60
appeared to have been invented around 1500 BCE
61
and was a device which relied on the steady flow of water from or into a container.
62
Measurements could be marked on the container or on a receptacle for the water.
63
It was reliable, but the water flow still depended on the variation of pressure
64
and temperature from the top of water in the container.
65
As the technology of glassblowing developed from some time in the 14th century,
66
it became possible to make sand glasses.
67
Originally, they were used as a measurement for periods of time like lamps or candles.
68
But as clocks became more accurate,
69
they were calibrated to measure specific periods of time.
70
The drawback, however, as you can imagine,
71
was the limited length of time they could measure.
72
The last timekeeper to be introduced is the fire candle clock.
73
Candle clocks took advantage of a simple concept,
74
the slow and consistent nature of a burning wax candle.
75
By utilizing this process, our ancestors were able to keep steady track of the time.
76
The clocks were created by engraving the length of the candle with evenly spaced markings.
77
Each marking represented a single unit of time,
78
and as the wax burned down, each hour would disappear.
79
However, the drafts and the variable quality of the wax mainly influenced the time of burning.
80
Like oil lamps,
81
candles were used to mark the passage of time from one event to another rather than tell the time of day.
82
That is the end of section 4.
83
You now have half a minute to check your answers.
84
That is the end of the listening test.
85
Please wait for the answers.
86
Thank you.

연습 팁

이 비디오에서 제공되는 스피치는 느리고 명확한 톤으로 진행됩니다. 따라서 shadow speech 방식으로 연습하기에 적합합니다. 우선 비디오를 천천히 듣고 주요 내용을 이해한 후, 한 문장씩 따라 발음해 보세요. 영어 쉐도잉 기법을 활용하여 음성을 따라하거나 반복하여 정확한 발음을 익히는 것도 좋습니다. 특히, 'shadowspeak' 접근법을 사용하여 표현의 리듬과 억양을 익히는 것이 중요합니다. 각 문장을 듣고 즉시 따라 하는 연습을 통해 IELTS 스피킹에서의 자신감을 높일 수 있습니다. 반복을 통해 자연스럽게 발음하고, 나의 언어 습관에 맞게 조정해 보세요.

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.
