1
Come on, get started!
2
Oh, what happened little kitty?
3
My clock has been stuck for an hour!
4
Ha ha ha!
5
It hasn't stopped.
6
It just switched back from daylight saving time.
7
What's that?
8
Well, to answer that, let me answer a question.
9
Why do we have
10
Daylight Saving Time?
11
Zoom in!
12
Before modern electric lighting became widely available, natural daylight was essential to everyday life.
13
Yes, its timing did not always match people's schedules.
14
In summer, the sun rose early and set late, giving people long hours of daylight.
15
But some of that morning light arrived while people were still asleep.
16
And by the time they finished work and had time for other activities, darkness was approaching.
17
If they wanted to continue working or spend time outside,
18
they had to rely on artificial light such as candles or oil lamps, which required fuel and resources.
19
This led to a simple question.
20
Could people organize their clocks differently so that more daylight fell during the hours when they were awake and active?
21
One early idea came from Benjamin Franklin.
22
In 1784, while living in Paris,
23
Franklin jokingly wrote about getting up earlier to make better use of sunlight and save candles.
24
He did not propose changing clocks, but his essay highlighted the potential of making better use of natural daylight.
25
More than a century later, a New Zealand insect collector,
26
George Hudson, wanted more daylight after work for his hobby.
27
In 1895, he proposed shifting clocks during part of the year.
28
William Willett later promoted a similar idea in Britain,
29
campaigning in 1907 for clocks to be moved forward so that more daylight could fall in the evening.
30
The idea became practical during the First World War.
31
In 1916, Germany and Austria -Hungary introduced seasonal clock changes,
32
partly to conserve fuel by reducing the need for artificial lighting.
33
Other countries followed and the United States adopted daylight saving time in 1918 as a wartime measure.
34
but what actually happens
35
when the clocks change in the united states for example the sun might naturally rise at 5 am
36
and set at 7 pm during summer most people are still asleep at 5 am
37
while many are awake and active at 7 pm when daylight saving time begins in spring the clock moves forward one hour.
38
Sunrise is then shown as 6 a .m.
39
and the sunset as 8 p .m.
40
The sun has not changed and no daylight has been created.
41
Only the clock has changed.
42
The idea was that this extra hour of evening daylight could give people more time for outdoor activities,
43
shopping, travel, exercise and social life while also reducing the need for artificial lighting.
44
But modern research shows that the energy effects are more complicated.
45
Lighting is only one part of energy use.
46
Heating, cooling, transportation and changes in daily behavior can also affect the overall result.
47
And changing the clock comes with its own challenges.
48
Moving it forward in spring can reduce sleep and temporarily disrupt the body's internal timing.
49
Research has found associations between the spring transition and changes in road safety and workplace injuries.
50
When clocks move back to their original time in autumn, people gain an hour of sleep,
51
but darkness arrives earlier in the evening.
52
So, this process often gets a mixed review.
53
Trivia Time!
54
Did you know, in the United States,
55
DST starts on the second Sunday in March and ends on the first Sunday in November?
56
Also, less than 40 % of countries worldwide use TST.
57
It's sketching time.
58
Today's sketch of the day goes to...
59
Moo -Nee.
60
Hope you learned something useful today.
61
Until next time, it's me, Dr. Binox, zooming out.
62
Saving daylight or not, Kitty's going to sleep anyway.
63
Never mind.

Qu'est-ce que la technique du Shadowing ?
Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
