完形填空(共20小题;每小题1.5分,满分30分)
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 brief pause it would make the necessary detour (绕道).   37  one point, the ant had to cross a crack(裂缝) 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.
