Shadowing Practice: IELTS listening practice Part 4 - the A.U.V (answer & transcript) - Learn English Speaking with Video

Creando lección...
1
Autonomous underwater vehicle, or AUV.
2
It actually resembles a miniature airplane that moves deep in the ocean.
3
It's not large enough to have a human crew aboard, and so its behavior is really that of a robot.
4
The AUV is programmed to calculate
5
and record a range of data depending on the mission it is carrying out at any one time.
6
On previous missions, it has been programmed to record water pressure, as well as how much salt there is in the water.
7
On a more recent mission around Bermuda, an AUV was equipped with a special instrument that showed the temperature of the ocean at different depths.
8
It can also assess the quality of the water in general.
9
So, as you see, it is quite a versatile and useful little piece of equipment.
10
We use its measurements to determine
11
and increase our understanding of ocean behaviors as well as its role in and influence on our climate.
12
This instrument also has many other benefits.
13
It can be launched and used relatively quickly.
14
Also, there's no need for cables to physically link it to a boat.
15
There are disadvantages, though.
16
AUVs move at only modest speeds, up to 25 centimeters per second.
17
In addition, the AUV structure cannot collect water samples, so other equipment must be used to conduct a chemical analysis of the water.
18
Now, I'm sure you're all wondering how the AUV actually works.
19
First, let's see how an AUV actually moves.
20
L. It moves by pumping oil between two bladders.
21
This helps the AUV to sink or float.
22
The AUV records the data and measurements that it has been programmed to take while it rises to the surface.
23
At the beginning and end of each dive, it obtains records and transmits its position by exposing an antenna embedded within the tip of the right wing.
24
Okay, so that's the AU.
25
Thank you.
26
Thank you.
27
Thank you.
28
Thank you.

¿Qué es la Técnica de Shadowing?

Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
