人教版必修1 Unit 4 Natural Disasters （主题：自然灾害）阅读与写作【单元主题工自然灾害Today, scientists worldwide are studying plants and animals to build a better class of robots. Many of the robots may help with future rescue. And while some of these nature-inspired robots are in the lab, at least one type of these robots has been tested during a big natural disaster.Months ago, a big earthquake shook central Mexico. The quake resulted in hundreds of deaths and destroyed thousands of buildings. Before long, volunteers asked scientists from a lab at the Carnegie Mellon University to bring their snake robots to Mexico City to aid in the rescue efforts.Soon, scientist Matthew Travers, one director of this lab, and other scientists reached Mexico City and traveled between the city's fallen-down buildings. They used the cameras on the heads of the snake robots to look into a building/s open spaces and check if people were trapped inside.In the past years, scientists at the Carnegie Mellon University have worked to develop snake robots. By changing the designs of the robots made before, they created a “unified snake robot” , which could move through different types of terrain （地形）.But Travers and his teammate Howie Closet said that the snake robots had somewhat limited success in the Mexico City earthquake. zz lt wasn't like what we had thought: we brought the snake robots down there and we won the war/'says Travers.The big reason was that the robots were not equipped with any microphones,speakers, or proximity sensors （接近感应器）,Such kinds of modern equipment would have greatly improved the snake robots' ability to communicate with people who were trapped or to map the environment/The reason why wedon/t have more equipment is only because of money,''says Choset.Research on snake robots continues to move on. But Choset says it remains a challenge to get money to develop search-and-rescue robots.阅读下面短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
