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.

视频中的语法

说话人最常用的结构，并附上视频中的原话：

结构视频中的用法
现在完成时 have/has + 过去分词 — 过去发生但与现在仍有关联的事has been stuck · hasn't stopped · has not changed
被动语态 be + 过去分词 — 强调发生了什么，而不是谁做的has been stuck · be moved · is then shown

需要注意的发音

  • “sh” 和 “zh” 音: artificial /ˌɑː.tɪˈfɪʃ.əl/, transition /tɹænˈzɪʃ.ən/
  • 长单词——注意重音位置: artificial /ˌɑː.tɪˈfɪʃ.əl/, naturally /ˈnæt͡ʃ.(ə.)ɹə.li/, complicated /ˈkɑm.plɪˌkeɪ.tɪd/, differently /ˈdɪf.ə.ɹənt.li/, temporarily /ˌtɛmpəˈɹɛɹəli/

中文母语者容易读错的音：

  • /v/ — 不要读成 /w/，上齿轻触下唇: arrive /əˈɹaɪv/, everyday /ˈɛvɹiˌdeɪ/, conserve /kənˈsɜː(ɹ)v/, trivia /ˈtɹɪvi.ə/
  • 词尾辅音 — 要读清楚，后面不要加元音: daylight /ˈdeɪˌlaɪt/, clock /klɑk/, arrive /əˈɹaɪv/, asleep /əˈsliːp/, darkness /ˈdɑɹk.nɪs/
  • /r/ 和 /l/ 的区别: naturally /ˈnæt͡ʃ.(ə.)ɹə.li/, practical /ˈpɹæk.tɪ.kəl/, partly /ˈpɑɹtli/, rely /ɹɪˈlaɪ/, differently /ˈdɪf.ə.ɹənt.li/

如何用这段视频练习

  1. 先完整听一遍视频，不要开口，记下不认识的单词。
  2. 用正常速度逐句跟读，每句重复到你的节奏与说话人一致为止。
  3. 录下自己的声音并与原声对比，特别注意 daylight, artificial, arrive 这类单词。

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
