是个辩题吧.
It is worthwhile to spend a lot of money on jewels.
Firstly,though jewels cannot be eaten,they are pretty and they can be appreciated.
Secondly,we can wear them to make ourselves much more attrative and elegant.
Thirdly,on the theory of economy,when a consumer buy a produce,actually he is buying its function.So jewels have prices,that means they do have a direct proportion of funtion.
Fourthly,also on the theory of economy,when the supply of a produce getting smaller,the price of this produce will arise.So if the jewel is unique,the prise of it should be very high,in the other word,it does worth some money.
