Well, the only place they speak german is in Germany, and the only place they speak french is in France (and some african countries). If you wan't to get around in europe, learn english. Allthough, if you have to learn a second language learn spanish. With spanish you can get around in half of south america. You can also communicate with portugese and italian people if you know spanish. Learning chinese is, exscuse me, kind of retarded. Yes, the most spoken language in the world is Mandarin, but the only place they speak it is china. Besides that, if you learn to speak a southern version of it, you probably won't be able to understand a guy from northern chinese because of the different accents and dialects. On top of that, in China, a lot of people speak english... Actually, don't even bother learning a second language, you'll do fine with english no matter where you go.
