阅读理解。

     A friend of mine,in response to a conversation we were having about the injustices of life,

asked me the question,"Who said life was going to be fair,or that it was even meant to be fair

?" Her question was a good one.It reminded me of something I  was taught as a youngster:life

isn't fair.It's a disappointment,but it's absolutely true.One of the mistakes many of us make is

that we feel sorry for ourselves,or for others,thinking that life should be fair,or that someday

it will be.It's not and it won't be.

     One of the nice things about surrendering (屈从) to the fact that life isn't fair is that it keeps

us from feeling sorry for ourselves by encouraging us to do the very best we can with what we

have.We know it's not "life's job" to make everything perfect:it's our own challenge.Surrendering

to this fact also keeps us from feeling sorry for others because we are reminded that everyone is

dealt a different hand;everyone has unique strengths and problems in the process of growing up,

facing the reality and making decisions;and everyone has those times that they feel unfairly treated.

     The fact that life isn't fair doesn't mean we shouldn't do everything in our power to improve our

own lives or the world as a whole.To the contrary,it suggests that we should.When we don't recognize

or admit that life isn't fair,we tend to feel pity for others and for ourselves.Pity,of course,is a selfdefeating

emotion that does nothing for anyone,except to make everyone feel worse than they already do.When

we do recognize that life isn't fair,however,we feel compassion (热情) for others and for ourselves.And

compassion is a heartfelt emotion that delivers lovingkindness to everyone it touches.The next time you

find yourself thinking about the injustices of the world,try reminding yourself of this very basic fact.You

may be surprised that it can make you out of selfpity and into helpful action.
