Pratica di Shadowing: IELTS listening practice Part 4 - the A.U.V (answer & transcript) - Impara a parlare inglese con i video

Creazione lezione...
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.

  2. Fai shadowing frase per frase a velocità normale, ripetendo ognuna finché il tuo ritmo coincide con quello di chi parla.
  3. Registrati e confronta con l’originale, facendo attenzione a parole come instrument, measurement, obtain.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
