This is a true story a friend of a friend experienced in his Australia holiday:
 
Two American tourists ''were driving (drive)'' on deserted roads through the bush when they accidentally hit a large kangaroo.
 
''Getting (get)'' out of the car, they realized that the kangaroo had died in the accident.
 
''Being (be)'' so drunk, though, they propped up the kangaroo, its lifeless head ''bouncing (bounce)'' from one side to the other,
dressed it in one of their new jackets, and took pictures of themselves with their arms around it.
 
Ater a few minutes of picture-taking, the guys were shocked when it seemed that the kangaroo came back to life! It turns out that the poor kangaroo wasn't dead, but it had passed out, and when it came back to consciousness started to box with the drunken guys! It actually broke one guy's jaw!! It then ''hopped(hop)'' away into the landscape.


<div align="center">
The men couldn't drive their rented car, as the keys were in the green jacket, which was still on the kangaroo, so they ''had to walk (must, walk)'' back to the tournament. A little while later, a pack of kangaroos was seen in the distance, one of them ''wearing(wear)'' the green jacket.

I <em>arrived (arrive)</em> in Eden, where signs to the Killer Whale Museum <em> had been displayed ()</em>(<abbr title="Die Geschichte ist in simple past, die Schilder wurden noch früher aufgestellt, &rarr; past perfect!">display</abbr>).

# Die Funktionswerte der Funktionen <math>f(x)</math> und <math>g(x)</math> addieren sich zu den Funktionswerten einer neuen Funktion <math>f(x) + g(x)</math>. Somit addieren sich auch die Flächeninhalte zwischen den Graphen von <math>f(x)</math> und <math>g(x)</math> und der x-Achse.
I <em> toured (tour)</em> the museum, and looked especially at the photos and skeletons of old killer whales. The story of what the museum called "A Modern Jonah" was certainly fascinating - but I found it hard to believe.  
# Der Grenzwert einer Summe ist gleich der Summe der einzelnen Grenzwerte, falls die Grenzwerte existieren: <math>\lim_{\Delta x \to 0} \ \sum_{i=0}^{\infty} \left( f(x_i)+g(x_i) \right) \cdot \Delta x = \lim_{\Delta x \to 0} \ \sum_{i=0}^{\infty} f(x_i) \cdot \Delta x + \lim_{\Delta x \to 0} \ \sum_{i=0}^{\infty} g(x_i) \cdot \Delta x</math>

Zur Schreibweise: <math>\sum</math> ist das Summenzeichen (großes griechisches Sigma), es gilt: <math>\sum_{i=0}^n f(x_i) = f(x_0) + f(x_1) + f(x_2) + \dots + f(x_n)</math>, d.h. der Index <math>i</math> durchläuft alle Zahlen von 0 (untere Summengrenze) bis <math>n</math> (obere Summengrenze).

Hours later, when the sun was going down, the whale came up again and ''died(die)''. The whalers took it and began their work on it. Suddenly they noticed strange movements ' from the whale's body. They cut it open and one of their missing mates, James Bartley, ''was found(find)'' inside the whale. He was unconscious, but he had survived – after fifteen long hours inside the whale's stomach.  
 
James Bartley was seriously ill for two weeks. He lost his hair and was nearly blind.  It was a month before he could speak again. Then he told his mates how it had happened. He had fallen into the whale's mouth, and had felt its huge teeth as he slipped down its throat into its stomach, where fish were swimming around. James Bartley's skin was a deadly white for the rest of his life. He lived another eighteen years.
