1
Three reasons why we should stop using nuclear energy.
2
1. Nuclear Weapons Proliferation Nuclear technology made a violent entrance onto the world stage.
3
Just one year after the world's first ever nuclear test explosion in 1944, two large cities were destroyed by just two single bombs.
4
After that, reactor technology slowly evolved as a means of generating electricity, but it's always been intimately connected with nuclear weapons technology.
5
It's nearly impossible to develop nuclear weapons without access to reactor technology.
6
In fact, the Nuclear Non -Proliferation Treaty serves the purpose of spreading nuclear reactor technology without spreading nuclear weapons with limited success.
7
In 40 years, five countries have developed their own weapons with the help of reactor technology.
8
The fact of the matter is
9
that it can be very hard to distinguish a covert nuclear weapons program from the peaceful use of nuclear energy.
10
In the 1970s, the big nuclear powers were happily selling peaceful technology to smaller countries, which then developed weapons of their own.
11
The road to deadly nuclear weapons is always paved with peaceful reactors.
12
2. Nuclear waste and pollution Spent nuclear fuel is not only radioactive,
13
but also contains extremely poisonous chemical elements like plutonium.
14
It loses its harmfulness only slowly over several tens of thousands of years.
15
And there is also a process called reprocessing, which means the extraction of plutonium from spent nuclear fuel.
16
It can be used for two purposes, to build nuclear weapons or to use it as new fuel.
17
But hardly any of it is used as fuel because we don't have the right kind of reactors for that.
18
A milligram will kill you, a few kilograms make an atomic bomb, and even an inconspicuous country like Germany literally has tons of the stuff just lying around
19
because reprocessing sounded like a good idea decades ago.
20
And where will all the waste go?
21
After dumping it into the ocean was forbidden, we've tried to bury it, but we can't find a place where it will definitely stay secure for tens of thousands of years.
22
Over 30 countries operate nearly 400 reactors managing several hundred thousands of tons of nuclear waste
23
and only one is currently serious about opening a permanent civilian waste storage, tiny Finland.
24
3. Accidents and Disasters Over 60 years of nuclear power usage,
25
there have been seven major accidents in reactors or facilities dealing with nuclear waste.
26
Three of those were mostly contained, but four of them released significant amounts of radioactivity into the environment.
27
In 1957, 1987 and 2011, large areas of land in Russia,
28
Ukraine and Japan were rendered unfit for human habitation for decades to come.
29
The number of deaths is highly disputed but probably lies in the thousands.
30
These disasters happened with nuclear reactors of very different types in very different countries and several decades apart.
31
Looking at the numbers, we may as well ask ourselves, are 10 % of the world's energy supply worth a devastating disaster every 30 years?
32
Would 30 % be worth another Fukushima or Chernobyl somewhere on Earth every 10 years?
33
What area would have to be contaminated so we say no more?
34
Where is the line?
35
So, should we use nuclear energy?
36
The risks may outweigh the benefits and maybe we should stop looking into this direction and drop this technology for good.

القواعد في هذا الفيديو

أكثر التراكيب التي يستخدمها المتحدث، مع العبارات نفسها من الفيديو:

التركيبفي الفيديو
المبني للمجهول be + اسم المفعول — التركيز على ما يحدث لا على من يفعلهwere destroyed · is always paved · was forbidden
المضارع التام have/has + اسم المفعول — حدث ماضٍ ما زال له أثر الآنit's always been · have developed · we've tried

نطق يحتاج إلى انتباه

يستخدم المتحدث 3 من الصيغ المختصرة، مثل can't, don't, we've. انطقها بصيغتها القصيرة كما تسمعها.

  • أصوات “sh” و“zh”: explosion /ɛkˈsploʊ.ʒən/, pollution /pəˈluʃən/, distinguish /dɪˈstɪŋ.ɡwɪʃ/, extraction /ɪkˈstɹækʃən/, habitation /ˌhæb.ɪˈteɪ.ʃən/
  • الكلمات الطويلة — انتبه لموضع النبر: electricity /ɪˌlɛkˈtɹɪsɪti/, radioactive /ˌɹeɪdioʊˈæktɪv/, contaminate /kənˈtæmɪneɪt/, habitation /ˌhæb.ɪˈteɪ.ʃən/, inconspicuous /ˌɪn.kənˈspɪk.ju.əs/

كيف تتدرب بهذا الفيديو

  1. استمع إلى الفيديو كاملًا مرة واحدة دون أن تتكلم، ودوّن الكلمات التي لا تعرفها.
  2. ابدأ بسرعة 0.75×، وردّد جملة جملة، ثم عُد إلى السرعة العادية عندما يصبح الأمر سهلًا.
  3. سجّل صوتك وقارنه بالأصل، مع الانتباه إلى كلمات مثل reactor, disaster, ton.

ما هي تقنية التظليل الصوتي؟

التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
