Question

    A six-wheeled robot travels underground in Hefei to discover warning signs of faults inside the pipeline network, "It looks like a toy car at first, but it's much more complicated than that," said Xu Mao, the robot 's operator.

The pipeline robot, developed by Wuhan Easy-Sight Technology, is made up of four parts — crawler, camera, cable reel, and controller. A full charge can enable the robot to work for four to five hours, covering a distance between 800 and 1 ,000 meters in the underground p ipeline.

The robot made its appearance last month in Shushan District. It will carry out inspections of the underground pipeline network stretching 150 kilometers. " Whether the pipe is leaking, damaged or blocked, we can clearly see its situation through high-definition(高清晰度的)cameras fixed into the robot, " said Qi Chuanshuai from the provincial construction engineering and testing institute.

The real-time data including video images of the pipe will be up loaded and displayed on a computer. "If we find any problems, we stop the robot and record the flaws," Xu said. "We report the faults to local government, who will arrange the repair as soon as possible. "

With the rapid develop merit of cities, it is becoming increasingly difficult to manage underground pipelines. Among all the difficulties, discovering faults in the sewage (污水)and rainwater pipelines comes first. Many other cities such as Wuhan, Nanjing, Shenzhen, and Shanghai are using the robots to inspect their pipelines, the robot ' s developer said.

Equipped with environmental detection sensors, the robots can monitor temperature and damp, poisonous gases, oxygen levels and smoke density, while providing color diagram in real time. "Compared with human workers, robots are able to enter smaller pipes and are immune (有免疫力的)to poisonous gases in sewage pipes," said Ge Shengli from Shushan District' s city management company. " No digging is required and there is no need to interrupt traffic," Ge added.

【解析】

本文是说明文。伴随着城市的快速发展，管理地下管道变得日益困难。研发人员发明了管道机器人，在很大程度上解决了这个难题。与人工处理管道问题相比，管道机器人的优势显而易见。

1.主旨大意题。根据第二段的内容可知，该段主要介绍了管道机器人的一些特征。故正确答案为C。

2.细节理解题。根据第五段中的信息With the rapid development of cities, it is becoming increasingly difficult to manage underground pipelines. Among all the difficulties, discovering faults in the sewage (污水) and rainwater pipelines comes first. 可知，伴随着城市的快速发展，地下管道的管理变得日益困难。在所有的困难中，找出污水和雨水管道的缺陷是第一位的。由此可知，城市地下管线管理最困难的是找出污水、雨水管道有缺陷。分析选项可知，D符合题意，故选D。

3.推理判断题。根据第五段的前半部分“机器人配备了环境检测传感器，可以监测温度和湿度、有毒气体、氧气浓度和烟雾密度，同时实时提供彩色图表。”可知，该段介绍了与管道机器人有关的一些背景知识，分析选项可知，A符合题意，故选A。

4.推理判断题。根据文章最后一段中的信息 “Compared with human workers, robots are able to enter smaller pipes and are immune (有免疫力的) to poisonous gases in sewage pipes,” said Ge Shengli from Shushan District’s city management company. “No digging is required and there is no need to interrupt traffic,” Ge added. 从Ge Shengli的话中可知，“与人类工人相比，机器人能够进入更小的管道，并且对污水管道中的有毒气体具有免疫力。不需要挖掘，也不需要交叉运输”，可知，这些内容列举出这种管道机器人与人类相比工作时的许多优点，由此可推断出Ge Shengli对于管道机器人的态度应该是积极的和赞赏的。故正确答案为B。
