Creazione lezione...
1
You will hear a lecture about how carbon dioxide is produced from food And what are the effects of the emission problem?
2
First, You have some time to look at questions 31 to 40.
3
Now listen carefully and answer questions 31 to 40.
4
Good afternoon.
5
Thanks for coming to today's lecture.
6
In the last few decades the environmental impact of food production and consumption has become one of the greatest concerns.
7
When we look at what we eat and how we produce the food, we can find extensive evidence for how we damage our environment.
8
Greenhouse gas emissions may come from livestock such as cows, agricultural soils and rice production.
9
According to statistics, the carbon dioxide emissions from the production of the food people
10
consume every day are almost the same as the emissions we make when we are driving.
11
Let's look at some more specific examples.
12
The cultivation and processing of 100 grams of coffee beans are responsible for 140 grams of carbon dioxide.
13
Now, some international organizations are training farmers in many countries to
14
use sustainable agricultural methods as a way of reducing their carbon dioxide emissions.
15
All agricultural practices have been found to have a variety of effects on the environment.
16
Some of the environmental effects are associated with meat production.
17
The popular red meat requires 28 times more land to produce than chicken,
18
11 times more water and results in 5 times more climate warming emissions.
19
According to another research, cooking process also causes greenhouse gas emissions.
20
Scientists now are working on how to best minimize its impact.
21
Another problem that we cannot neglect is the packaging of food products.
22
as packaging takes a lot of energy, water and other natural resources to produce.
23
So a lot of natural resources are wasted.
24
when we throw the packaging materials away.
25
Furthermore, Packaging waste produces a big amount of greenhouse gas.
26
To make things even worse, the food we eat often comes from places far away.
27
Therefore, the transportation of our food across long distances contributes to air and water pollution.
28
In recent decades with the growing number of population, more food is in demand.
29
So more land has been used to produce food.
30
Hundreds and even thousands of forests have been cut down.
31
It had a devastating effect on the climate because forests can absorb greenhouse gases.
32
People in different parts of the world apply various kinds of farming practices.
33
In most countries, cows and other livestock are kept on the farms, while in some countries they are kept in a restricted area on a mountain,
34
but they all contribute to the carbon dioxide emissions.
35
And for animal agriculture, the problem can be more serious because the livestock need food all the time.
36
In America, cows eat an overwhelming amount of corn and soybeans each year.
37
In order to create a better world for us and our future generations, we should adopt sustainable agriculture.
38
The goal of sustainable agriculture is to meet the world's growing demand for food at the present without affecting future generations.
39
Every person involved in the food system, growers, food processors, distributors, retailers,
40
consumers and waste managers can play a role in ensuring a sustainable agricultural system.
41
There are many practices commonly used by people working in sustainable agriculture and sustainable food systems.
42
Crop growers may change their food production methods to prevent pollution.
43
Although some other areas of agriculture are very hard to change such as fishing,
44
Consumers and retailers concerned with sustainability can look for foods that are environmentally friendly.
45
However, Sustainable agriculture is more than a collection of practices, It is also a process of negotiation.
46
a push and pull between the competing interests of an individual farmer
47
or of people in a community as they work to solve complex problems about how we grow our food.
48
In conclusion, I want to emphasize
49
that we may not be able to go back to the old times and live a simpler lifestyle,
50
but we can take an active role in preventing more environmental problems caused by carbon dioxide emissions.
51
In the next lecture, I will share some of the studies and effective solutions with you.
52
That is the end of Section 4.
53
You now have half a minute to check your answers.
54
That is the end of the listening test.
55
In the IELTS test, you would now have 10 minutes to transfer your answers to your answer sheet.

Il contesto: l'impatto ambientale della produzione alimentare
Nel video, una lezione spiega come la produzione e il consumo di cibo generino diossido di carbonio e danneggino l'ambiente. Dai bovini alla cottura, passando per l'imballaggio e il trasporto, ogni fase contribuisce alle emissioni. Un contesto reale che ci invita a riflettere, ma anche a esercitare l'ascolto e la pronuncia in inglese. Ecco come usarlo per migliorare la pronuncia inglese e praticare il shadowing.
Frasi e collocazioni utili da memorizzare
- Greenhouse gas emissions: emissioni di gas serra (una collocazione chiave per argomenti ambientali)
- Sustainable agricultural methods: metodi agricoli sostenibili (fondamentale per discussioni su sviluppo verde)
- Climate warming emissions: emissioni che causano il riscaldamento climatico (utile per descrivere effetti ambientali)
- Food system: sistema alimentare (un termine complesso ma frequente in contesti globali)
- Push and pull between competing interests: tensione tra interessi contrastanti (una frase figurativa per esprimere conflitti)
La tua sfida di shadowing: imita e migliora
Per esercitarti con il shadow speech, segui questi passaggi: riproduci un frammento del video (ad esempio, la parte sulle emissioni della carne rossa), ascolta attentamente l'intonazione e il ritmo, poi ripetilo immediatamente dopo, cercando di imitare ogni suono. Usa un shadowing site o semplicemente YouTube: metti in pausa, ripeti e confronta. Questo esercizio aiuta a rafforzare la pronuncia e la fluidità. Ricorda: l'obiettivo è non solo capire, ma imparare l'inglese con YouTube in modo attivo. Prova per 5 minuti al giorno e noterai i risultati!
La grammatica di questo video
Le strutture che chi parla usa di più, con le parole esatte del video:
| Struttura | Nel video |
|---|---|
| Forma passiva be + participio passato — conta ciò che accade, non chi lo fa | is produced · have been found · are associated |
| Present perfect have/has + participio passato — un’azione passata che conta ancora adesso | has become · have been found · has been |
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.
