This behavior is interesting to scientists, who 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. Choe found that Argentine ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead — take me away.”But there's a twist to Choe's discovery. Choe says that the living ants— not just the dead ones — have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, it's telling other ants that it's dead.What keeps ants from dragging away the living ants? Choe found that Argentine ants have two additional chemicals on their bodies, and these tell nearby ants something like, “Wait — I'm not dead yet.”So Choe's research turned up two sets of chemical signals in ants: one says, “I'm dead.” the other set says, “Wait — I' m not dead yet.”Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious, for example, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive. Many scientists think there must be a chemical on a dead ant's body.Choe suspects that when an Argentine ant dies, the chemical that says “Wait —I'm not dead yet” quickly goes away. Once that chemical is gone, only the one that says “I'm dead” is left. When other ants detect the “dead” chemical without the “not dead yet” chemical, they drag away the body.Understanding this behavior may help scientists figure out how to stop Argentine ants from invading new places and causing problems. Choe would like to find a way to use the newly discovered chemicals to spread ant killer to Argentine ant nests.The ants' removal behavior is important to the overall health of the nest. “Being able to quickly remove dead individuals and other possible sources of disease is extremely important to all animals living in societies, including us,” says Choe.“Think about all the effort and money that we invest daily in waste management.”1. The underlined word “twist” in Paragraph 3 means ______.A. an unexpected changeB. a clear mistakeC. an important keyD. a shocking conclusion2. Ants judge whether another one is dead or not depending on ______.A. the sense of tasteB. the sense of touchC. the sense of smellD. the sense of sight3. The result of the research can be used to ______.A. kill troublesome pestsB. solve the problem of endangered speciesC. prevent invasive species in advanceD. keep the balance of nature4. Why is it important to remove dead individuals?A. Because it is easier to manage the living.B. Because it can save money to deal with the waste.C. Because it can provide more space for the living.D. Because it can keep the living from suffering disease.5. What might be the best title of the text?A. Dead or living? It is easy to judgeB. Pulling away the dead ants is a difficult taskC. Ant nests have great undertaking capacityD. Leaving it alone or taking it away? Ants feel puzzledⅣ. 写作(25 min.)(原创)生活中,我们总是有这样或那样的负担。
