都浪费掉了 <-- they are all wasted 美人 <-- a beautiful woman 那 <-- something in the far distance 這<- something in the close distance 那麼 / 這麼 is a Chinese phrase, means "in this/that degree" 那這麼 Does not exist in the language. It is just putting chunks of Chinese characters together with no real meaning. I can 100% tell you that this is not a Chinese sentence. In conclusion, this is an "ALIAN" language and cannot be translated. :) XD

If you want to say 那么美的一个人都浪费掉了，it's fine in grammar, but it does not make sense. You can say: 那么好的饭菜都浪费掉了，太可惜了。 And you can say: 那么美的一个人（or 那样一个美人），时光白白虚度（了），太可惜了。

I think this isn't a whole sentence ,and a little hard to be understood .Can you give a whole sentence even English one.

I want to help you but that isn't a complete sentence. Could you write a conplete one?
