问题     In deference to a world enthralled by shows like "Extreme Makeover" and "Keeping Up With the Kardashians," the public school district in Washington has hired a reality television company to produce videos intended to improve the skills of its teachers. The 80 videos, 5 to 15 minutes in length, are peppered with quick jump cuts, slick screen labels and a jaunty soundtrack. In short interviews and classroom snippets, the district’s highest-performing teachers demonstrate how they teach a range of lessons, from adding decimal numbers to guiding students of differing ability levels through a close reading of the Marshall Plan.
    The videos, financed by a $900,000 grant from the Bill and Melinda Gates Foundation, were developed as a complement to Washington’ s evaluation system, known as Impact, in which teachers are judged on student test scores and classroom observations. Through these evaluations, versions of which are being put in place across the country, teachers receive feedback on the areas where they need to improve, as well as a numerical rating. But many of Washington’s teachers complained that they needed examples of the highest performing level. Because teachers spend most of their days isolated in their own classrooms, they rarely get a chance to observe their peers. The videos give them a way to peek behind the closed doors of their colleagues.
    Now, with new national curriculum standards driving teachers to modify their longstanding teaching practices, a broad range of school districts, universities, companies and nonprofits are rushing to develop online video libraries showing model teaching. A nonprofit group allied with the New York State Department of Education is developing a series of about 200 videos demonstrating lessons aligned with the Common Core standards for reading and math that 45 states and the District of Columbia have adopted. Teaching Channel, a nonprofit, has a collection of more than 500 professionally produced videos of teachers recommended by school districts and other teacher organizations. The University of Michigan is indexing about 16,000 videos of fourth- through ninth-grade English and math teachers in six urban districts. And hundreds of amateur clips have been uploaded to YouTube by individual teachers.
    Education experts warn that video needs to be part of a broader program of professional development, comparing the use of video in teaching to how it is used by athletes. In Washington, evaluators and principals will recommend specific videos to teachers. Jill Nyhus, senior director of technology for the Washington schools, said principals or instructional coaches would also convene gatherings where teachers could discuss the videos.
According to the passage, we can know that Impact______.
选项 A、is a complement to Washington’ s evaluation system
B、tells how well teachers perform in their teaching
C、is developed with the help of Bill and Melinda Gates Foundation
D、focuses on students’ test scores and their classroom performance
答案B
解析 根据题干关键词定位至第二段。由第一句可知，被称作“影响评估法”的体系就是华盛顿的教学评价体系．通过学生的考试分数和课堂观察来判断教师的工作表现，因此B项“告诉教师们在教学中表现得多好”为正确答案。第二段第一句说明视频是对Impact系统的补充，不能说Impact是华盛顿教育评价体系的补充，因此排除A项“是华盛顿教育评价体系的补充”：第二段第一句说明比尔·盖茨和梅琳达·盖茨基金会为这些视频提供了资助，而不是该基金会为Impact提供了资助，因此排除C项；第二段第一句说体系注重的是学生的考试分数以及课堂观察，而不是注重学生在课堂中的表现，因此排除D项。
