Unit 3-The world of science单元综合能力测试 时间：100分钟　　　满分：120分 　选择题部分 第二部分　阅读理解(共两节，满分40分) 第一节(共15小题；每小题2分，满分30分) 阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 A Earthquake rescue robots have experienced their final tests in Beijing. Their designers say that with these robots, rescue workers will be able to have more time to save more lives during an earthquake. 　　This robot looking like a helicopter(直升机), is called the detector-bot. It’s about 4 meters long, and it took about 4 years to develop the model. Its main functions(作用) are to collect information from the air, and send goods of up to 30 kilos, to people stuck in an earthquake. 　　This robot has a high quality 360 degree panoramic camera. It can work day and night and will also be able to send the latest pictures from the quake area. Dr. Qi Juntong, Chinese Academy of Science, said, “Unlike other automatic machines, the most important feature of this robot is that it doesn’t need a distant control. We just set the information of the earthquake-struck area on it, and then it takes off, and lands by itself. It flies as high as 3, 000 meters, and as fast as 100 kilometers per hour. ” 　　This robot has a different function—it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go. 　　As well as a detector(探测器)that finds victims(遇难者)and detects poisonous gas, a camera is placed in the 40-centimeter-long robot, which can work in the dark. 　　Another use for the rescuers is the supply bot, with its 10-meter-long pipe. People who are caught in the ruins will be able to get supplies including oxygen and liquids. 　　Experts have said that the robots will enter production, and serve as part of the national earthquake rescue team as soon as next year. 1.

The amount of girls interested in STEM careers stayed unchanged. 　　But t ... ...
