Two cats were walking through a forest. Suddenly, they found a loaf(条)of bread lying under a tree. Both pounced(猛扑)on it and caught the bread at the same time. Neither would give up and after having fought for a while, they decided to divide it into two pieces and take one piece each. “But how do we divide it?” one cat said.

A monkey sitting on a branch of a tree saw what had happened between the two cats. He got an idea. He came down from the tree and walked up to the confused(迷惑的)cats.

“Hi, my dear friends! Can I help you?” the monkey asked. The cats told the monkey what the problem was and asked, “Can you divide the bread for us?” The monkey agreed.

The monkey broke the bread into two pieces. But one piece was a little bigger than the other. “Oh no! I will take a little bite(咬一口)of this bigger piece to make both equal(大小相等的),” the monkey said. He took a bite from the bigger piece. “Uh oh!” But the bite he took was too big.” Now it has become smaller than the other piece. I will just have to take a little bite from this piece now,” the monkey said.

The monkey took another bite. The two cats sat in front of the monkey, seeing the loaf of bread get smaller and smaller. When the whole bread was finally gone, the monkey said, “I am sorry. It was really difficult to divide that bread. I must be going now.” He jumped back into his tree and was gone.

“If only we had not fought against each other, we could have stuck together(团结在一起) and kept our bread,” the two cats said.

Humans have many ways to communicate like making phone calls, writing messages, or talking face to face. 【小题1】 So how do they communicate?

Just like humans, some insects use sound to communicate. Male crickets (蟋蟀) can “sing” by rubbing their legs on their wings. The sound is an invitation to female crickets, which says, “I’m here! Come on over!”

【小题2】 Ants produce special smells called pheromones (信息素). They use pheromones to mark paths to food after they find it. When they follow the path back home, they make more pheromones along the way. The pheromones can invite more ants.

Bees use their sense of smell to communicate, too. 【小题3】 It smells like bananas. If you smell bananas near a hive (蜂房), you should move away as fast as you can. Or you’ll be attacked as an enemy.

Bees also communicate in another way. After a bee finds food, it goes back to its hive and does a dance. Other bees around it can feel the dance moves. 【小题4】

Insects also use touch to communicate, such as ants. When an ant is following a leader, it will tap (轻拍) the leader’s legs with its antennae (触须). 【小题5】 That way, no one gets left behind.

A.Insects don’t have these choices.
B.The dance’s pattern gives them directions to the food.
C.Other insects use their sense of smell to communicate.
D.That tells the leader that the other ants are keeping up.
E.Ants use their antennae to communicate with their leaders.
F.If a bee sees an enemy, it produces a pheromone that tells the other bees to attack.
