问题     From humble beginnings in a garage in Menlo Park, California in 1998, Google has grown into a multinational company carrying out over one billion Internet searches every day.
    Google’s most famous product is Google Search. Searching Google【C1】______relevant sources is now as standard a procedure for historians as【C2】______for library catalogues. But it does have【C3】______: online databases and non-textual information, such as pictures, cannot always be【C4】______by Google or other search engines. Such sites have to be searched【C5】______, which is dependent on knowing they exist.
    Google Search is not the only tool that Google offers to historians. Google Maps and a(n)【C6】______tool called Google Earth together provide high-resolution (高分辨率) satellite images, street maps and terrain【C7】______for many areas of the world. Google Maps can be used to【C8】______down the exact location of where something happened, or to give a new perspective on old interpretations:【C9】______the position of First World War trenches, for example, or mapping the journey of Marco Polo.
    Google also provides tools that【C10】______historians to work together. Google Scholar allows historians to find work that is【C11】______to their own, whether produced by fellow historians or【C12】______from different disciplines.
    For historians looking to collaborate, Google Docs allows documents to be accessed and edited by multiple users【C13】______: historians in different universities researching the same topic can write up【C14】______articles on their findings. Google Wave and Google Buzz are two new messaging and social up【C15】______tools that enable real-time conversations online.
    Google is also【C16】______a significant role in producing digital versions of sources that would otherwise be【C17】______to archives and museums. Google Books is a project, carried out in【C18】______with a range of universities and libraries, to digitize millions of their books and make them【C19】______on the web. As a result, historians can search for key words or phrases in over 10 million books, from the earliest【C20】______texts to the present day.
【C3】
选项 A、merits
B、limitations
C、advantages
D、restrictions
答案B
解析 名词辨析题。本段开头指出谷歌搜索引擎很常用，也很方便，接着转折连词But表明此处应该要说明它的缺点。因此B)limitations“局限”符合文意。A)merits“优点”和C)advantages“优势”与原文意思相反；D)restrictions“限定”不符合文意。
