1
Ever walked up a flight of stairs and wondered why running up feels so much harder?
2
Think about what it takes to get up stairs.
3
With every step, your muscles lift your body against gravity.
4
If you ran up instead, you'd still have to lift your weight through the same height.
5
That's where power comes in.
6
Power tells us how quickly work is done.
7
To find average power, divide the work by the time it takes.
8
Work is measured in years, time in seconds, and power in watts.
9
So, if you see a power rating of one watt, that means one gear of energy is transferred every second.
10
Let's put some numbers to that.
11
Imagine a climb that takes 1 ,200 years of work against gravity.
12
If you take 12 seconds, your average power is 100 watts.
13
What if you do that same climb in 6 seconds?
14
Now you're doing 200 years of work each second.
15
Half the time, twice the power.
16
Imagine taking a ride in a sports car.
17
The driver presses the accelerator and you feel yourself pressed back into the seat as the car picks up seats.
18
The car is gaining kinetic energy.
19
How quickly can its engine supply energy?
20
Take a 400 kilowatt engine.
21
At full power, it can deliver 400 ,000 joules of mechanical energy every second.
22
Now picture a standard halfback on an everyday drive.
23
It can reach motorway speed, too.
24
Suppose this engine is rated at 60 kW.
25
At full power, that's 60 ,000 wheels every second.
26
If the two cars have similar mass, they need roughly the same gain in kinetic energy to go from rest to motorway speed.
27
With similar grip and losses, the more powerful car can get there seen.
28
Now let's look at the world's fastest landowner, the Cheetah.
29
Imagine how quickly it has to gather speed when it chases its head.
30
In just a quick drive, its muscles give its body a big increase in kinetic energy.
31
That's a burst of high power.
32
Compare that with a hard -working husky.
33
Picture it pulling a light sled along a snowy trail.
34
Once the sled is gliding at a steady speed, is the husky still doing work?
35
It is.
36
The snow resists the sled's motion, so the husky has to keep pulling.
37
Its talent is disdaining that effort over a long distance.
38
Next time you head upstairs, Think about two questions.
39
How much work does it take to lift you to the top?
40
And how quickly do you do it?
41
The first tells you about the energy changes.
42
Put that together with the time taken and you have your average path.
43
Thank you.

Wortschatz und Sprechhinweise zu dieser Lektion

Diese Sprechübung basiert auf dem Video „Power – Rate of Work“. Diese Wörter kommen am häufigsten vor: energy, speed, quickly, husky, kinetic. Dieses Video enthält 43 Sätze und 431 Wörter zum Nachsprechen. Der gesprochene Teil dauert 3:26. Der Sprecher spricht gleichmäßig mit etwa 126 Wörtern pro Minute – ein angenehmes Tempo fürs Shadowing. 83 % der Wörter gehören zu den 3.000 häufigsten im Englischen; den Rest solltest du dir vor dem Üben ansehen.

Phrasal Verbs, die du hören wirst

WortBedeutung

Aussprache, auf die du achten solltest

  • Lange Wörter – auf die Betonung achten: mechanical /məˈkænəkəl/, accelerator /əkˈsɛl.əˌɹeɪ.tɚ/

Laute, die Deutschsprachigen schwerfallen:

  • /w/ — mit runden Lippen, nicht wie das deutsche „w“ (/v/): watt /wɑt/, motorway /ˈməʊtəweɪ/, kilowatt /ˈkɪ.ləˌwɒt/
  • Stimmhafter Auslaut — /b/, /d/, /g/, /z/, /v/ am Wortende nicht verhärten: stairs /ˈstɛɹz/, divide /dɪˈvaɪd/, upstairs /ˌʌpˈstɛɹz/, sled /ˈslɛd/, glide /ˈɡlaɪd/
  • /æ/ — offener als „ä“: gravity /ˈɡɹævɪti/, rat /ɹæt/, mechanical /məˈkænəkəl/, gather /ˈɡæðɚ/, halfback /ˈhæfˌbæk/

So übst du mit diesem Video

  1. Höre dir das ganze Video einmal an, ohne zu sprechen, und notiere die Wörter, die du nicht kennst.
  2. Sprich Satz für Satz in normaler Geschwindigkeit nach und wiederhole jeden, bis dein Rhythmus zum Sprecher passt.
  3. Nimm dich auf und vergleiche mit dem Original; achte dabei auf Wörter wie watt, muscle, climb.

Was ist die Shadowing-Technik?

Shadowing ist eine wissenschaftlich fundierte Sprachlerntechnik, die ursprünglich für die professionelle Dolmetscherausbildung entwickelt und durch den Polyglotten Dr. Alexander Arguelles populär gemacht wurde. Die Methode ist einfach aber wirkungsvoll: Du hörst englisches Audio von Muttersprachlern und wiederholst es sofort laut — wie ein Schatten, der dem Sprecher mit nur 1–2 Sekunden Verzögerung folgt. Anders als passives Hören oder Grammatikübungen zwingt Shadowing dein Gehirn und deine Mundmuskulatur, gleichzeitig echte Sprachmuster zu verarbeiten und zu reproduzieren. Studien zeigen, dass es Aussprachegenauigkeit, Intonation, Rhythmus, verbundene Sprache, Hörverständnis und Sprechflüssigkeit signifikant verbessert — was es zu einer der effektivsten Methoden für die IELTS Speaking-Vorbereitung und reale englische Kommunikation macht.
