山东省烟台栖霞市（五四制）2021-2022学年七年级下学期 期中考试英语试题 第二部分阅读理解（共两节,满分22.5分）第一节（共4小题；每小题1.5分,满分22.5分） 阅读下列短文,从短文后每题所给的A、B、C和D四个选项中,选出最佳选项。 A A robot walks on four legs. It stops in front of a chair and a mist（雾气）comes out of its head. The robot turns itself to the left, then to the right, then up and down. There is always germ（病菌）in our house. The robot is using it to clean germ on the chair. After that, the robot will move on to the next one. “Named LASER-D, it’s a robot dog,” said Yiyu Chen, one of its designers（设计者）. His team already tested LASER-D in different places. Chen hopes that in the future the robot will know other things on its own and find out how to clean each side of a thing. The team also wants to give LASER-D an arm so that it can open doors or move things. At the University of Virginia, some people are testing another robot. This one, DINGO, looks more like a giraffe. It cleans things with ultraviolet light（紫外线）. The light comes out from the sides and bottom（底部）of the robot. At the same time, its neck turns around, sending out more light onto the chairs, desks and other things in a room. Of course, people can disinfect（消毒）rooms as well, but this job is dangerous. Because of COVID-19, so many places need to be cleaned, but there may not be enough people to get the job done. Maybe people need more robots to do the work over and over again without getting tired. 1. What is LASER-D doing according to the first paragraph? ________ A. Practicing walking on legs. B.
