I paid 30 yuan for a watermelon the other day. When I ate it at home I found it more bitter than sweet. I was 36   to throw it away for it cost me money 37  . But to eat it was a 38  thing no better than tasting goldthread(黄连)
Things like this  39  occur in our daily life. For example, last week when going on a tour we failed to find the  40  we had been seeking.  41  we were so unfortable as if on pins and needles(如坐针毡).In such a case we had better  42  home immediately, but most of us tourists still chose to  43  our way until we finished visiting all the scenic spots,  44  actually we did not quite enjoy them.
If we   45   , we’ll get nothing; we would have spent money  46  .If we don’t give up, what we’ve got is something to cause suffering or pain, or    47  disaster. Since that’s the case, why are we still unwilling to  48 with it? The only 49 _ is: it means money.
Then what 50     does money contain? Its importance lies in none 51     the following two aspects: (1) it can be used for our living;(2) it can be used for daily life. When a sum of money that should be able to obtain joy or enjoyment is certain to 52 the purpose, isn’t it wise to give it up? Isn’t it a sort of 53 for money-spending or even for enjoying ourselves?
To abandon and forget a sum of money that is to be of no value or to produce   54  values can be counted as   55 value of money. Isn’t it so?
