Music Recording 16 Let's find out just how environmentally aware you are.
2
Question 1.
3
How many trees do you think it would take to offset the CO2 emissions from a long-distance flight?
4
Well, it's estimated that for each mile,
5
or 1.6 kilometres, that a jet flies,
6
half a kilo of CO2 is added to the atmosphere.
7
So, a round trip of 10,000 miles would emit about one and a half tonnes of CO2 per passenger.
8
The amount of CO2 a tree can absorb depends on factors such as its type,
9
location and age.
10
The company Future Forests says that on average it would take two trees 99 years to counter the effect of this trip.
11
So the answer here is C.
12
Question 2.
13
What is the most environmentally friendly way to wash your clothes?
14
Well, the solvents used by most dry cleaners are damaging to the environment.
15
In a washing machine, the vast majority of the energy,
16
about 90% of it, goes into heating up the water,
17
not running through the cycle.
18
Washing clothes in hot water,
19
even by hand, uses a lot of energy to heat the water.
20
Keeping washing temperatures low and always washing a full load is the best policy.
21
So the correct answer is C.
22
Question 3.
23
Do you need to always turn off your electric lights to save energy?
24
It is a common myth that flicking the lights on and off uses more energy than leaving them on.
25
In fact,
26
an ordinary bulb only has to be turned off for three seconds to outweigh the cost of turning it back on.
27
For energy efficient and other fluorescent bulbs,
28
this rises to five minutes.
29
Energy efficient light bulbs use 75% less energy than ordinary ones,
30
so if you have those but leave them on as you tidy,
31
you'll probably still use less energy than if you switch your standard bulbs on and off.
32
So the correct answer is B.
33
Question 4.
34
What is the most energy efficient way of cooking a baked potato?
35
A microwave uses just a third of the electricity required to operate an electric oven.
36
And, of course, the potato will take much less time to cook.
37
So the correct answer is B.
38
Question 5.
39
What is the best way to help reduce your CO2 emissions throughout the year?
40
Well, it's estimated that one person taking the train for a year,
41
rather than driving a car,
42
would reduce their CO2 emission total by 2.9 tonnes.
43
Hanging out your washing, rather than using a tumble dryer,
44
would cut CO2 by 0.9 tonnes,
45
and working from home one day a week would cut 0.88 tonnes.
46
So the correct answer is A.
47
Recording find out just how environmentally aware you are.

Perché esercitarsi a parlare con questo video?

Praticare la conversazione in inglese con il video "Unit 16 | The energy crisis" è un metodo efficace per migliorare la tua fluidità e comprensione del linguaggio quotidiano. Questo video offre un contestuale prezioso sull'argomento della crisi energetica, integrando vocabolario specialistico e situazioni reali che potresti affrontare durante una discussione. Utilizzando shadow speech e shadowspeak, puoi cogliere le sfumature nella pronuncia e nell'intonazione, che sono cruciali per comunicare efficacemente. Attraverso la ripetizione e l'immedesimazione, puoi notevolmente migliorare la tua pronuncia inglese.

Grammatica ed espressioni in contesto

Analizzare le strutture linguistiche del video ti permetterà di apprendere utile vocabolario e frasi chiave. Ecco alcune strutture degne di nota:

  • Condizionali e domande retoriche: Frasi come "How many trees do you think it would take..." incoraggiano il pensiero critico e l'uso di forme condizionali.
  • Comparativi e superlativi: Espressioni come "the most energy efficient way" aiutano a fare confronti in modo naturale.
  • Imperativi e consigli: Il video utilizza frasi come "Keep washing temperatures low" per dare indicazioni pratiche, il che è utile per imparare a formulare suggerimenti in inglese.

Utilizzando queste strutture nei tuoi esercizi di shadowing in inglese, puoi migliorare la tua capacità di esprimerti in modo chiaro e conciso.

Trappole comuni di pronuncia

Durante la visione del video, presta attenzione a parole che possono risultare difficili da pronunciare. Alcuni esempi includono:

  • Environmentally: Questo termine è lungo e presenta una pronuncia specifica con l'accento sulla seconda sillaba.
  • Efficient: Anche in questo caso, è importante battere il ritmo sulla seconda sillaba per rendere la parola fluida.
  • Contribute: Fai attenzione alla pronuncia della "u" e alla sequenza di consonanti che possono creare confusione.

Questo tipo di attenzione ai dettagli ti aiuterà a migliorare la tua pronuncia in inglese e a sentirti più sicuro durante le conversazioni.

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.
