Question

7．What is big data exactly？Good question．After all，we've always had large amounts of data．As Laurie Miles，head，of analytics for big data specialist SAS，says，"The term big data has been around for decades and we've been，doing analytics all the time．It's not big； it's just bigger．"Most traditional data was structured，or neatly organized in databases．Then the world went digital and the Internet came along．Most of what we1 do could be translated into data capable of being recorded，stored，searched，and analyzed．There was also so-called unstructured data generated by all our digital interactions （互動），from emails to online'shopping，text messages to tweets，and Facebook updates to YouTube video's．
Some say that about 90% of all the data in the world today has been created in the past few years．"About 75% of data is unstructured，coming from sources such as text voice and video，"says Mr Miles．
"Big data is not just historic business intelligence，''says Mr，Miles．"It's the addition of real-time data and the ability to combine together several data sets that makes it so valuable．"Practically，anyone who makes，grows and sells anything Can use big data analytics to make their manufacturing and production processes more efficient arid their marketing more targeted and cost-effective．
And many businesses are only just beginning to realize that data is something that they need to protect and use．"Banks only use a third of their available data because it often sits in databases that are hard to access，"says Mr Miles，"We need to find ways to make this data more easily accessible．"
Who owns it all？Social media platforms will often，say that their users own their own content，but then lay claim to how that content is used，reserving the right to share it with third parties!So when you tweet you effectively give up any control over how that tweet is used in future，even though Twitter terms and conditions say，"What's yours is yours．"Privacy （隱私） and intellectual property1 laws have not kept up with the pace of technological change．

Answer 1

分析 本文講述了大數(shù)據(jù)時代的到來得益于數(shù)字科技的發(fā)展，但是由此而來的隱私問題也受到人們的關(guān)注．

解答 DBBD
32．D 考查細(xì)節(jié)理解．根據(jù)"The term big data has been around for decades and we've been，doing analytics all the time"可知，大數(shù)據(jù)是指已經(jīng)研究了很多年的數(shù)據(jù)．故選D．
33．B 考查細(xì)節(jié)理解．根據(jù)"Most of what we1 do could be translated into data capable of being recorded，stored，searched，and analyzed．There was also so-called unstructured data generated by all our digital interactions"可知，我們對數(shù)字科技活動有越來越多的接觸，這對非結(jié)構(gòu)化數(shù)據(jù)的開發(fā)有很大的幫助．故選B．
34．B 考查段落大意．根據(jù)"It's the addition of real-time data and the ability to combine together several data sets that makes it so valuable"可知，第三段講述了大數(shù)據(jù)的價值．故選B．
35．D 考查細(xì)節(jié)理解．根據(jù)"Banks only use a third of their available data because it often sits in databases that are hard to access"可知，因?yàn)楹茈y訪問消費(fèi)者的信息，所以銀行只使用他們數(shù)據(jù)的一小部分．故選D．

點(diǎn)評 閱讀理解考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．
