你太厉害了，很多中国人也不知道这些古文什么意思。"关关"是水鸟鸣叫的声音（the sound of water birds），"在河之洲"是栖息在河中的沙洲（resting in the shoal of the river），This is an ancient poetry in China,It is almost useless in daily communication.you just need to know it or recite the first two sentences(关关雎鸠，在河之洲。窈窕淑女，君子好逑。) when you are pursueing a girl.If you want to know some detail information you may talk to me via skype(naughtyboy577).

這是古代情歌的歌詞，這都是古代中文了，現在用得少，就算中國人也有不少不知道它的具體含義。你知道它的大概意思就行了：The gentle bird which sings near the river's beach.
