One morning I wasted nearly an hour watching a tiny ant carry a huge feather．Several times, it 36 several obstacles in its path．And after a momentary pause it would make the necessary detour （绕道）． 37 one point, the ant had to cross a crack about 10mm wide．After some 38 thoughts, the ant laid the feather over the crack, walked 39 it and picked the feather up 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 failings．
After some time the ant 44 reached its destination --- 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 48 and using great brightness, overcoming problems a1l along the way, just gave up the 49 and went home．The ant had not thought the problem through 50 it began its journey and in the end the feather was 51 more than a burden．Isn’t our 52 like that?
We worry about our families; we worry about the 53 of money; and we worry about all kinds of things．These are all burdens --- the things we pick up along life’s path, 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．
