Your trip is based on tasks you have to solve during the following lessons.

The navigation on the left leads you to the tasks and worksheets.

Use your notebook or a document on your PC to write down the information you got.

Return to the task list when you have finished an excercise.

Prepare well because after the work with the internet we'll discuss your opinion - you'll have to argue!

If you don't know a word you need to understand the whole text, you can look it up in an online-dictionary, eg. http://www.pons.de.
But try to understand the vocabulary in the context before using this help, please.
