11
Tornadoes come from giant thunderstorms called supercells.

The mixing of cold and warm air causes the air to spin.
15
The spinning wind turns into a cloud in a funnel shape.
16
As the cloud turns, the wind becomes stronger.
17
When the funnel cloud touches the ground, it is a tornado.
18
Measuring tornadoes.
19
Scientists have a way to measure the strength of tornadoes.
20
They look at the harm caused by a tornado.
21
They use the amount of harm to estimate the wind speed.
22
They use a special scale called the EF scale.
23
The EF scale measures the strength of the tornado.
24
Where tornadoes form.
25
Tornadoes may be hard to measure,
26
but scientists have a good idea where they'll strike.
27
It's true that a tornado can hit anywhere in the world at any time.
28
Most tornadoes happen in the central part of the United States.
29
This area is called Tornado Alley.
30

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.
