B．The FCC should be put under strict supervision.
C．Rules need to be set to diversify online services.
C．Rules need to be set to diversify online services.
D．Broadband providers' rights should be protected.
D．Broadband providers' rights should be protected.
细节题。根据最后一段中的“The endless legal battles and back-and—forth at the FCCcry out for Congress to act”可知，无休止的法律斗争和FCC的反复无常迫切需要国会采取行动，故本题选A。由该段中的“It needs to give the commission explicit authority once and for all to bar broadband providers frommeddling in the traffic on their network and to create clear rules protecting openness and innovation online”可知，应该是FCC监管其他机构，而非FCC受到监管，B项“FCC应接受严格管控”可排除。此外，制定规则是要维护网络环境的开放创新，而非促进在线服务多样化，C项“需制定促进在线服务多样化的规定”可排除。文中提及要限制宽带供应商的行为而非保护其权力，D项“宽带供应商的权力应得到保护”可排除。

As a historian who's always searching for the text or the image that makes us re-evaluate thepast, I've become preoccupied with looking for photographs that show our Victorian ancestorssmiling (what better way to shatter the image of 19th-century prudery?). I've found quite a few,and--since I started posting them on Twitter —they have been causing quite a stir. People have beensurprised to see evidence that Victorians had fun and could, and did, laugh. They are noting that theVictorians suddenly seem to become more human as the hundred-or-so years that separate us fadeaway through our common experience of laughter.
Of course, ! need to concede that my collection of Smiling Victorians makes up only a tinypercentage of the vast catalogue of photographic portraiture created between 1840 and 1900, themajority of which show sitters posing miserably and stiffly in front of painted backdrops, or staringabsently into the middle distance. How do we explain this trend?
During the 1840s and 1850s, in the early days of photography, exposure times were notoriouslylong: the daguerreotype photographic method (producing an image on a silvered copper plate) couldtake several minutes to complete, resulting in blurred images as sitters shifted position or adjustedtheir limbs. The thought of holding a fixed grin as the camera performed its magical duties was toomuch to contemplate, and so a non-committal blank stare became the norm.
But exposure times were much quicker by the 1880s, and the introduction of the Box Brownieand other portable cameras meant that, though slow by today's digital standards, the exposure wasalmost instantaneous. Spontaneous smiles were relatively easy to capture by the 1890s, so we mustlook elsewhere for an explanation of why Victorians still hesitated to smile.
One explanation might be the loss of dignity displayed through a cheesy grin. "Nature gave uslips to conceal our teeth," ran one popular Victorian saying, alluding to the fact that before the birthof proper dentistry, mouths were often in a shocking state of hygiene. A flashing set of healthy andclean, regular pearly whites was a rare sight in Victorian society, the preserve of the super-rich (andeven then, dental hygiene was not guaranteed).
A toothy grin (especially when there were gaps or blackened teeth) lacked class: drunks,tramps, and music hall performers might gum and grin with a smile as wide as Lewis Carroll's gum-exposing Cheshire Cat, but it was not a becoming look for properly bred persons. Even Mark Twain,a man who enjoyed a hearty laugh, said that when it came to photographic portraits there could be "nothing more damning than a silly, foolish smile fixed forever".
According to Paragraph 1, the author's posts on Twitter________.
A．changed people's impression of the Victorians
B．highlighted social media's role in Victorian studies
C．re-evaluated the Victorians' notion of public image
D．illustrated the development of Victorian photography
