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.
We can learn from the passage that the new national curriculum standards______.

选项 A、call for more professionals to put their video clips onto the websites
B、combine the school district, universities, companies and nonprofits together
C、indirectly cause the appearance of more video clips of model teaching
D、attract more funds from the nongovernmental organizations

答案C

解析 根据题干关键词定位至第三段。由第一句可知,新的国家课程标准使得教师们不得不改变自己的教学习惯.从而最终促使各种组织机构大量开发视频教学的相关内容,故C项“间接导致了更多模范教学视频的出现”为正确答案。A项“促使更多的教师把自己的视频放到网上去”,B项“把学区、大学、公司和非营利性机构联合在一起”,D项“从各类非政府组织中吸引了大量投资”,原文均没有提到。
