Scientists have always been interested in the high level of organization in ant societies.American researchers have watched ants build life-saving rafts to keep afloat (飘浮的) during floods. They also have recordedhow ants choose their next queen—the female whose job is to produce eggs.
New technology is helping to improve researchers’ understanding of the insects. But there is still a lot to be learned.
Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide.
David Hu is an engineer with the Georgia Institute of Technology, also known as Georgia Tech, saying, \you have100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at keeping this network. \
David Hu and other Georgia Tech researchers wanted to study ants and the secret of their engineering. They froze antrafts and then looked at them with the help of computed technology, or CT images.The pictures showed that larger ants serve in central positions to which smaller ants hold. The larger ants create pockets of air that keep the insects afloat
Scientists say small robots or materials that can change shape could be programmed in a similar way, working towardsa shared goal.

Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen.

34. Why did the larger ants serve in central positions in their ant rafts? A. To stress their importance. B. To protect themselves. C. To fight against their enemies. D. To defend the queen
35. What ideas do the ants give us according to the passage? A. We can use similar-shaped machines in flooding areas. B. We can combine small robots or materials into larger ones. C. Small and shape-changeable things might work just like ants do. D. Small robots or materials in the shape of ants can be made. 第二节（共5小题；每小题2分，满分10分）
