I have to write an exame in English on Wednesday.
We have a Text in our book, I must to read the text more and more so that I understand it.
The topic will I to leave off.
New York and Toronto may think they are more cosmopolitan, but London in the 21st century is certanly the most diverse city ever. This is one of the reason why it chosen to host the 2012 Olympic Games. More than 300 languages are spoken by the people of London, and it has 50 nationalities with populations of more than 10,000.
I will trying to translate it in German.
New York und Toronto dürfen denken, sie seien kosmopolitischer, aber London, im 21. Jahrhundert, ist mit Sicherheit die vielfältigste Stadt überhaupt. Das ist einer der Gründe wieso sie zu den Veranstaltungen der Oylmpischen Spielen gewählt wurde.
Mehr als 300 Sprachen werden von den Londoner (oder von den Leuten aus London) gesprochen, .....
The last past of the sentence is to hard for me, I can't understand what is meaning of this.
I need your help.
You said I should write some essays in English, here is one of them
Progressive Form gebildet wird aus einer Form von "be" und dem Present Participle (-ing Form des Verbs). 
ein kleiner Tipp: pass nächstes Mal auf, dass der Text nicht doppelt erscheint, das schreckt ab, denn von einem kurzen Text konnte auf den ersten Blick ja keine Rede sein. Hast Du teilweise möglicherweise ein Übersetzungsprogramm benutzt? Es ist auffällig, dass ab und zu haarsträubende Fehler vorkommen. Mach das bitte nicht! Wir erwarten schon, dass sich die Fragenden selber auch Mühe geben, bevor wir uns mit den Fragen beschäftigen, OK?!My discussion lesson deals with a very current topic: the ongoing debate about nuclear energy and alternative energy sources.Since the earthquake in Japan and the resulting incident at the atomic power plant in Fukushima there have been many of articles and reports about the nuclear phase-out and renewable energies in the media.I suppose, all of you have already formed your opinion about this topic and have decided whether your are for or against atomic power plants. But now I want to give you some facts and informations about the energy in Switzerland.This is a graphic account about the energy generation/power production in Switzerland. It dates back to 2009, but there have not been any significant changes until now.You see that forty percent of the electricity comes from the atomic plants stations Mühleberg, Gösgen, Leibstadt and Beznau I and II.It is quite amazing that the ratio of new renewable energy sources only amounts to 2 percent. Taking a closer look we discover that wind and solar power together account for only 1 percent. And these are the two sources mostly discussed at the moment. It obviously means that we have an enormous potential for using these energy sources in Switzerland, yet.But the fact that we have this theoretical potential is not sufficient. It is also important that this way of producing energy is suitable for the natural conditions of our country. Nobody would build a hydroelectric plant in a desert, would they?Do we have enough sun in Switzerland? Do we have enough wind in Switzerland?Especially regarding the question of wind there are many different opinions. A lot of people claim that the averaging amount of wind is not sufficient. I would very much like to learn about your opinion about this point in the forthcoming discussion.All the arguments in favour of a rapid withdrawal from the nuclear energy programme sounds convincing enough at first, but it is also important to make sure that the current supply is guaranteed without the energy from the atomic power plants.]Because I can't edit my post I'll write a new
