Hello, Jane.

I’m writing from Jeremy’s house. I’m here because he has allowed me to use his computer. This is really annoying. You know how much work I do on my computer and right now I can’t even use it. My brother borrowed it the other day and when he was playing a stupid game 1online (against some friends of his), he felt that it was too slow. To make it a bit faster he shut down the 2_____________________ program,3_____________________ and everything! When I got back from my basketball practice the computer was switched 4_____________________ .

I 5_____________________ it on, but it took ages before it started. And even then, every program I tried to use, 6_____________________ within a minute or two. Nothing 7_____________________. I wanted to write my English essay, but I couldn’t. I thought I had too many programs installed, so I tried to 8_____________________ some I didn’t really need. I couldn’t. The computer 9_____________________ in the middle of the process. I tried hard to make it work, but in the end I had to10_____________________ the hard drive.

I need to 11_____________________ the operating system again now and all the programs that I want to use. And all that because my brother prefers my computer to his own! Which is now also broken, by the way! I’m lucky it’s only been a week since I last made a12____________________ on my external drive.

I must finish my essay by the day after tomorrow and I’ve just started working on it! Mr Brown won’t like it if I’m late again.

Anyway, I just wanted to drop you a line and say hi. I should get back to my essay now.

See you,

Joe

Rabbit Plague in Australia

Balance in nature is very fragile. Even very small changes in nature can cause great problems. The story of rabbits in Australia is a good example of this.

Originally, there weren’t any rabbits in Australia. European settlers first brought them there in 1788. They kept them for food. Half a century later, more and more people started to breed rabbits and they became more common. But they didn’t present a problem for the environment because they lived in cages.

In October 1859 everything changed when a man called Thomas Austin set 24 wild rabbits free. Austin’s favourite hobby was hunting. He wanted to create a population of rabbits in Australia so that he could hunt them. He asked a relative in England to send him some grey rabbits. When he released them, he didn’t think there would be any problems. After that many other people also released their rabbits into the wild.

The conditions in Australia were very different from those in England: the winters were mild and there were no foxes or other natural enemies. This was ideal for a population explosion. Ten years later, two million rabbits could be shot every year and it didn’t really affect the overall population.

The ecology of Australia has changed a lot because of rabbits. Many animal species have disappeared because rabbits eat all their food. They also cause a lot of damage to farmers, because they eat too much grass on the pastures, so there isn’t enough food for sheep. They also eat everything that farmers grow in the fields.

People have tried to control the rabbit population in different ways. They have shot them, destroyed their holes and built a rabbit-proof fence, which is more than 3000 km long, in Western Australia. They have even introduced a virus. It killed about 500 million rabbits. The population of rabbits that survived recovered and soon increased again. Even today, Australians are still trying to control the rabbit population.

Glossary: rabbit plague – zajčja kuga, species – vrsta (živalska ali rastlinska), damage – škoda, release – spustiti na svobodo.
