In this video I repeat the question, give a short answer and (as a learner) play a bit with the pronunciation, supported by playing on the keyboard.

There are two main categories : HelpNeeded and Warnings.
In the case of HelpNeeded, the most important phrase is simply the expression: "Help"!
.. perhaps with extensions like: "Help, I am hurt on the leg, I need a doctor".
In case of Warnings, you need the expression: "Attention"! .. perhaps with additional hints like:
"Attention, there are poisonous snakes on your path".

Please dear peers give as many video examples as possible from your experience, where you needed help or gave warnings. Thank you. I can only sketch the idea of an Open Hyperlinked Video Dialog (with many branches) for learning English. As I am not a native speaker (as hopefully many others soon), please leave your feedback for corrections and improvements and most important, please step in with your own video question , video suggestion or video response.
