Emily, I think you have the same problem I do. You speak and understand spoken Mandarin much better than you read and write it, 对吧？(dui ba?). You know how to input Pinyin to write Hanzi, but sometimes you pick the wrong character, right? So you wrote "我是一四岁" when you meant 我十四岁。I think. "我从英国来" I don't think the Chinese would say "I come from China" unless they are outside of the country. I think you want to say 我是英国人, because you are currently still living in the UK. I could be wrong, and I would appreciate it if a native Chinese would answer this.

Hello ,i'd like to be your chinese speaking partner .you will be free to talk with me through whatsapp,facebook,twitter or even wechat if you'd like .im currently living in china .please let me know if you are interested in
