问题     A solid majority of technology experts and stakeholders participating in the fourth future of the Internet survey expect that by 2020 most people will access software applications online and share and access information through the use of remote server networks, rather than depending crucially on tools and information housed on their individual, personal computers. They say that cloud computing will become more dominant than the desktop in the next decade. In other words, most users will perform most computing and communicating activities through connections to servers operated by outside firms.
    Among the most popular cloud services now are social networking sites(the 500 million people using Facebook are being social in the cloud), webmail services like Hotmail and Yahoo mail, microblogging and blogging services such as Twitter and WordPress, video-sharing sites like YouTube, picture-sharing sites such as Flickr, document and applications sites like Google Docs, social-bookmarking sites like Delicious, business sites like eBay, and ranking, rating and commenting sites such as Yelp and TripAdvisor.
    Most of those surveyed noted that cloud computing will continue to expand and come to dominate information transactions because it offers many advantages, allowing users to have easy, instant, and individualized access to tools and information they need wherever they are, locatable from any networked device. Some experts noted that people in technology-rich environments will have access to sophisticated-yet-affordable local networks that allow them to "have the cloud in their homes. "
    Many of the people who agreed with the statement that cloud computing will expand as the internet evolves said the desktop will not die out but it will be used in new, improved ways in tandem with(伴随)remote computing. Some survey participants said they expect that a more sophisticated desktop-cloud hybrid(混合物)will be people’s primary interface with information. They predicted the desktop and individual, private networks will be able to provide most of the same conveniences as the cloud but with better functionality, overall efficiency, and speed. Some noted that general-purpose in-home PC servers can do much of the work locally via a connection to the cloud to tap into resources for computing-intensive tasks.
    Meanwhile,a number of people said cloud computing presents difficult security problems and further exposes private information to governments, corporations, thieves, opportunists, and human and machine error, etc.
    Survey participants noted that there are also quality of service and compatibility hurdles(障碍)that must be crossed successfully before cloud computing gains more adopters. Among the other limiting factors the expert respondents mentioned were: the lack of broadband spectrum to handle the load if everyone is using the cloud; the variability of cost and access in different parts of the world and the difficulties that lie ahead before they can reach the ideal of affordable access anywhere, anytime; and complex legal issues, including cross-border intellectual property and privacy conflicts.
We can learn from the first paragraph that______.
选项 A、cloud computing is a special machine operated by some companies
B、desktops access software applications through stored tools and information
C、computing and communicating cannot be carried out without cloud computing
D、cloud computing will replac e desktops completely in the near future
答案B
解析 由题干提示定位到第一段。B)与第一段第一句"绝大多数人会在线获得应用软件和服务……而不是像现在这样主要依赖个人电脑上的工具和信息"语义一致，因此B)为正确答案。
