One morning I wasted nearly an hour watching a tiny ant carry a huge feather．Several times, it  36  obstacles（障碍物in its path．And after a pause it made the necessary detour. At one point, the ant had to  37  a crack(裂缝) about 10 mm wide．After some brief thoughts, the ant laid the                    38  over the crack, walked across it and  39  up the feather on the other side, then continued on its way．I was  40  by the cleverness of this ant．It was only a small insect, lacking in  41  yet equipped with a brain to reason, explore, discover and overcome.  42   this ant, like the other two-legged creatures  43  on the earth, also shares human feelings．
After some time the ant finally reached its  44  – a flower bed and a small hole that was the entrance to its   45  home．It was there that the ant met its  46  . How could that large feather possibly   47   such a small hole? Of course, it couldn’t．So the ant, after all this trouble and using great brightness, overcoming problems all along the way, just   48  the feather and went home. The ant had not thought the problem through   49  it began its journey and in the end the feather was   50  more than a burden. Isn’t our   51   like this?
We worry about our families; we worry about our money or the   52  of it; and we worry about all kinds of things．These are all  53  —the things we pick up all the life, and drag them around the obstacles and over the cracks that life will bring, only to   54  that at the destination they are   55   and we can’t take them with us．
