[Schroeder]

So here is my "German" version:
1.You are a witness of a very serious car accident. You give first aid and you see a group of gathering people. You do not have a cell phone to call the ambulance and you must ask someone to do it.
Would someone of you please stop standing around and call an ambulance?! (said with polite words but an angry tone to it.)

2.You see a teenager littering at the front of your house. Take a verbal action.
Hey, you have lost something! (in an ironic tone)

3. You sit in a restaurant. Suddenly you smell gas. Warn the guests and the staff.
Excuse me, I smell gas here! Does anyone else too?

4. You work in a company and you have to take 2 additional days off though you have done it twice this month. Ask your boss.
Sir, I know I have already taken 4 days off this month but I'm afraid I need two additional days. (I have some very pressing private business to do that can't be postponed.)

5. You stay at you grandmother who is a bit deaf. She is watching a TV program and disturbs you in learning. React.

Grandma, would you please turn down the volume a little? It is impossible for me to learn like this.
