Two friends visited the zoo together. The zoo was very large and it was   36   to go everywhere. They had to decide where and which animal to visit as their time was   37  . So both of them agreed not to   38   after choosing a   39   at every fork (岔路口).

A road sign at the first fork   40   one way to the lion quarters and the other to the tiger hill. They decided on the   41   after a   42   discussion because lions were “the king of the grassland”. The second showed a division (路口) going separately to the panda and peacock. They   43   panda as it was the nation’s treasure and went its way. Thus they made choices all along the way and each choice meant   44   what they could regret. But they had to make it  45  , for it brooked (容忍) no delay. If they hesitated they would miss  46  . Only   47   decision could offer more chances for sightseeing and   48   possible regret.

Life is  49  like this—choices often occur that one has to make, for example, between two  50   jobs, two fascinating wooers (追求者). To get one you   51   give up the other—you can get half of it. If you   52   weighing the pros and cons(权衡利弊) and calculating gains and losses, you will most likely   53   empty-handedness. Don’t be sad about it.  54   you have got half of the desirable things in life—something that is   55   to get.
