In today's lecture I'm going to talk about changes in air pollution since the middle of the last century
2
and what has created these changes.
3
So by the 1950s air pollution was very visible with frequent
4
thick black fogs known as smogs in many large cities around the world.
5
The main source of this pollution was from factories and it caused severe health problems.
6
For example, a particularly severe smog in London in 1952 caused over 4,000 deaths.
7
Obviously, something had to be done.
8
And in 1956, a Clean Air Act was introduced in Britain.
9
This addressed the pollution from factories and the smog soon disappeared.
10
However, as you know, these days air pollution is still a big issue.
11
The main difference between now and the 1950s is that you can't see it, it's invisible.
12
Also, the main source of pollution now is from cars and lorries, and although these don't produce visible signs, this air pollution is still a significant risk to health.
13
And one of the key factors in the rise of this type of pollution is
14
that we have all become much more vehicle dependent.
15
There are far more cars and lorries, trains and planes than in the 1950s, and this is now the main source of air pollution around the world.

Wat is de Shadowing-techniek?

Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
