One morning I wasted nearly an hour watching ...

One morning I wasted nearly an hour watching a tiny ant carry a huge feather. Several times, it 31 several obstacles in its path. And after a momentary pause it would make the necessary detour (绕道). 32  one point, the ant had to cross a crack about 10mm wide. After some 33

thoughts, the ant laid the feather over the crack, walked 34  it and picked the feather up on the other side, then continued on its way. I was 35  by the cleverness of this ant. It was only a small insect, lacking in 36  yet equipped with a brain to reason, explore, discover and overcome.37  this ant, like the other two-legged creatures 38  on the earth, also shares human failings.

After some time the ant 39  reached its destination—a flower bed and a small hole that was the entrance to its 40  home. It was there that the ant met its 41  .How could that large feather possibly 42  such a small hole? Of course, it couldn’t. So the ant, after all this 43  and using great brightness, overcoming problems all along the way, just gave up the 44  and went home. The ant had not thought the problem through 45  it began its journey and in the end the feather was 46  more than a burden. Isn’t our 47  like that?

We worry about our families; we worry about the 48  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 49  that at the destination they are

50  and we can’t take them with us.

C

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure--and so soon--that another ant is dead.

One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead--take me away” when it is dead.

But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait— I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.

To test his theory, Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.

Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

B. When an ant dies, it can tell others using a certain chemical.

C. A living ant can pretend to be dead using a special chemical.
