Shadowing Practice: Responses to Stimuli - Learn English Speaking with Video
Les maken...
1
An eagle flies high in the sky.
2
It uses its keen sense of sight to search for fish in the lake below.
3
When it spots a fish, it dives down and catches it in its sharp talons.
4
All organisms respond to stimuli.
5
A stimulus is a change of signal in an organism's environment that the organism can recognize and react to.
6
In the case of the eagle, the stimulus was spotting the fish in the water.
7
The reaction to that stimulus is called a response.
8
The eagle's response to seeing the fish was to swoop down and catch it.
9
Responses help an organism survive and adapt to its environment.
10
Plants for instance have unique ways of responding to stimuli.
11
Many plants react to light, a process known as phototropism.
12
plants turn their heads to follow the sun across the sky, soaking up as much sunlight as possible for photosynthesis.
13
Another type of response in plants is towards gravity, a process known as geotropism.
14
This response guides roots to grow downwards into the soil, and stems upwards towards the sky.
15
An interesting example of plant response to stimulus is the Venus flytrap.
16
This carnivorous plant closes its leaves when an insect lands on them, capturing its prey for digestion.
17
Animals also exhibit a wide array of response to stimuli.
18
For instance, a rabbit, upon sensing a predator, instinctively runs to escape, demonstrating a basic survival mechanism.
19
Similarly, when a gazelle senses a change in the wind direction carrying the scent of a predator, it quickly alters its cause to avoid detection.
20
Birds too respond to seasonal changes.
21
As winter approaches, many species migrate to warmer regions, ensuring their survival during harsh weather conditions.
22
Even a simple organism like an earthworm reacts to light by moving away from it, preferring to stay hidden in the dark soil.
23
Even the simplest organisms such as single-celled amoeba or paramecia have the ability to respond to stimuli.
24
For example, if these microorganisms encounter a harmful substance, they will move away from it.
25
But if they detect a food source, they will move towards it.
26
These examples demonstrate that the capacity to respond to stimuli is an essential characteristic of all organisms,
27
helping them interact with their environment, adapt to changes and ensure their survival.
28
Thank you.

Woordenschat en spreektips bij deze les
Deze spreekles op niveau B2 is gebaseerd op de video “Responses to Stimuli”. Deze woorden komen het vaakst terug: response, organism, plant, stimuli, stimulus. Deze video bevat 28 zinnen en 382 woorden om na te spreken. Het gesproken deel duurt 3:35. De spreker praat langzaam, ongeveer 107 woorden per minuut, zodat je tijd hebt om elke klank na te doen. Slechts 71% van de woorden hoort bij de 3.000 meest gebruikte Engelse woorden, dus de woordenschat is pittig.

- Neem jezelf op en vergelijk met het origineel; let daarbij op woorden als stimulus, organism, react.
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.
