Maybe not 'most' - it's hard to say - but there are certainly more people in Germany who speak English well than in many other European countries. I believe that the European countries with the highest proportion of fluent English speakers are the Scandinavian nations (Sweden, Norway, Denmark) and Holland (the Netherlands). Next in the list comes Germany, I would say. Germans have an advantage over some other nationalities because English and German have many elements of vocabulary and grammar in common. English grammar, in some ways, is like a simplified German. Germans also do not have the pronunciation problems that, for example, Spanish people have. Another indication is the number of Germans here on italki who have excellent English. There are very few non-native speakers of English here who write perfect, faultless English, but among those who do, the majority are Germans.

No they don't,also Russian don't speak English as well

Germany is physically close to England. For centuries their royal families were mixed up in ways I don't understand... The English (and U.S.) custom of the "Christmas tree" was a German tradition, introduced into England by Queen Victoria's husband and cousin, Prince Albert. Both countries have a strong tradition of Protestantism. English and German have a degree of linguistic similarity. So--despite fighting each other in World War I and World War II--the two countries have tended to think of themselves as having a certain degree of cultural connection.

it's make me laugh!! but they really are?? my experience says they are so so.....

i don't think so. i know some german friends, their English isn't really good.
