1、承德一中高二直播课堂检测 英语试题（考试时间： 120分钟 满分：150分 ）第一部分阅读理解(共两节，满分55分)第一节(共15小题；每小题3分，满分45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。AThe International Day of Disabled Persons, an international observance declared by the United Nations since 1992, is observed on December 3, aiming to promote an understanding of disabil
2、ity issues and get support for the rights of people with disabilities. The day takes place annually and focuses on a different issue each year. In South Africa, December 3 also marks the beginning of the Disability Awareness Month.Since the first celebration, people with disabilities have gained rec
3、ognition of their rights by states across the globe and of their rightful place in society. But there is still much work ahead of us to turn those legal rights into a true revolution, in which diversity is fully accepted and lived.The estimated one billion people living with disabilities worldwide f
4、ace many obstructions of inclusion in many key aspects of society. As a result, people with disabilities cant enjoy the equal rights as normal people, which include employment, education as well as social and political participation. The right to participate in public life is essential to create sta
5、ble democracies , active citizenship and reduce inequalities in society.In many cases, people with disabilities must be able to fulfill their role in society. It is important to focus on the ability and not on the disability of an individual. It is important to note that disability is part of the hu
6、man condition, and that all of us either are or will become disabled to one degree or another during the course of our lives.By promoting empowerment , real opportunities for disabled people are created. This supports them in setting their own priorities. Empowerment involves investing in them in jo
7、bs, health, nutrition, education, and social protection. When disabled people are empowered, they are better prepared to take advantage of opportunities, and they can more readily accept their civic responsibilities.1What is the International Day of Disabled Persons meant for?ATo raise money for the
8、 disabled.BTo stress the value of the disabled.CTo make an international celebration.DTo make ablebodied people care about the disabled.2What does the underlined word “obstructions” in Paragraph 3 mean?AChances.BTypes.C Barriers DRegrets.3What is the main problem for disabled people?AThe number of t
9、hem is too large.BThey cant be fully accepted by society.CFew of them seek legal rights.DThey think poorly of their role in society.BA team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new hig
10、htech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.“Its extremely important for us to think about this as a whole system and not just the sum of a bunch of individual
11、components,” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the goahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those compon
12、ents are off the shelf and so we have to develop them all on our own，” he said.They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually ha
13、s to perform well, but then has to be matched well to everything its connected to，” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manu
14、factured.While this first robotic flyer is linked to a small, offboard power source, the goal is eventually to equip it with a builtin power source, so that it might someday perform datagathering work at rescue sites，in farmers fields or on the battlefield. “Basically it should be able to take off,
15、land and fly around，” he said.Wood says the design offers a new way to study flight mechanics and control at insectscale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions,
16、you know, to study biology in ways that would be difficult with the animals, but using these robots instead，” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a daytoday basis.”4The difficulty the team of engineers met with while making the robotic fly was that _.Athey had no model in their mindBthe
