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.

One day an ant was drinking at a small stream and fell in. She made desperate efforts to reach the side, but made no progress at all. The poor ant almost exhausted was still bravely doing her best when a dove saw her. Moved with pity, the bird threw her a blade of grass, which supported her like a raft, and thus the ant reached the bank again. While she was resting and drying herself in the grass, she heard a man come near. He was walking along barefooted with a gun in his hand. As soon as he saw the dove, he wished to kill it. He would certainly have done so, but the ant bit him in the foot just as he raised his gun to fire. He stopped to see what had bit him, and the dove immediately flew away.

One day while walking along the bank of a river, a rabbit couple saw a wounded(受伤的) ant lying unconsciously(没有直觉地) on the grass. The rabbit couple gently put the ant on the leaf of a nearby plant. She soon recovered(恢复) and saw the rabbit couple sitting beside her.
The ant remembered that she had found herself under the foot of a cat by chance and fainted(晕倒). She asked how she reached the leaf top. The rabbit couple told her what had happened. The ant thanked them and said she would help them when they needed help.
The rabbit couple went further up the river to enjoy the bright sun. They had been there many times and would spend many hours playing and relaxing in the sun.
One fine day, the couple were again on their way to the river while the ant was playing on the leaf of a tree. She saw the rabbit couple walking towards the river. A few hours later she saw them sleeping peacefully on the soft grass by the river. Suddenly she saw a lion moving towards the grass where the rabbit couple were sleeping. The lion saw the rabbits sleeping, and started walking quietly to attack them.
Realizing the hazard getting close to the rabbits, the ant jumped from the leaf to the lion’s shoulder and bit(咬) the lion’s back. The lion cried out in pain, waking the rabbit couple. The rabbits ran away quickly and the ant jumped off the lion’s back into the grass.

When a close friend dies, it often forces you to consider your own death. The more you have in common with the friend, the more his death will make you wonder about your own. Sometimes you will naturally say to yourself, "It could just as easily have been me." Such a death has a way of reminding us how fragile life is, and it may cause you to reassess(重新评价) the direction of your own life.

He kept thinking of the death of his friend. Jack thought about how much his friend missed in life and he saw how hard it was for his friend's family to manage after he passed away.
Jack realized that he didn't want to end up his life that way. He talked his feelings over with his wife and children, and decided to change his way of life. The family moved to a small town where he started a simple life. Now he is running a small art gallery(画廊). He is relaxed, and says he has never been so happy in his life, and he has got no more chest pain.
