没人么？

Hello everyone, my name is Joyce, I am fifteen years old. I'm very outgoing and l can talk with everyone .l like singing very much. And I usually sing to my friends,i think music can bring me lots of happiness.so today, I come here to make my dream come true

suggest you to spend more time to study grammar

求修改，求指教

有错误！楼上是正确滴，另外，i am outside应该改为“i am outging”.i like singing very much太幼稚了，可以这样说i extremely like singing.i usually.....friends改为i am always singing to my friends或i would like to singing to my friends.so today改为therefore

渣翻，仅供参考

翻译是，我认为，，，快乐：i consider that music can enable me to get a world of happiness，实现我的梦想：live up to my dream.放在文中则是，i come here,living up to my dream.

here是adv,不能有“to”,类比“go home”!

pursue my dream.追逐我的梦想
