举一反三：
[单选题]Across a wide variety of fields, data are being collected and accumulated at a dramatic pace. There is an urgent need for a new generation of computational theories and tools to assist humans in(96)useful information(knowledge) from the rapidly growing(97)of digital data. These theories and tools are the subject of the emerging field of knowledge discovery in database(KDD). At an abstract level, the KDD field is concerned with the development of methods and techniques for making(98)of data. The basic problem addressed by the KDD process is one of mapping low-level data(which are typically too voluminous to understand and digest easily) into other forms that might be more(99)(for example, a short report), more(100)(for example, a descriptive approximation or model of the process that generated the data), or more useful(for example, a predictive model for estimating the value of future cases). At the core of the process is the application of specific data-mining methods for pattern discovery and extraction.
A. expiring
B. examining
C. extracting
D. extricating
[单选题]对核能持批评态度的人抱怨继续经营现有的核电厂可能会导致严重的危害。但是这样的抱怨并不能证明关闭这些核电厂是合理的；毕竟，它们的经营导致的危害还不及燃煤和燃油发电厂——最重要的其他电力来源——产生的污染所导致的危害大。以上论述依据下面哪个假设?
A. 仅当能证实核电厂的继续运行会比现在运行已造成的危害大时，现有的核电厂才应该被关闭。
B. 关闭核电厂会大量增加对燃煤发电厂和燃油发电厂的依靠性。
C. 到目前为止，现有燃油和燃煤发电厂的运营产生的危害已经相当大。
D. 继续运行核电厂可能产生的危害能根据它们以前产生的危害可靠地预测。
[单选题]WLANs are increasingly popular because they enable cost-effective connections among people, applications and data that were not possible, or not cost-effective, in the past. For example, WLAN-based applications can enable fine-grained management of supply and distribution(66) to improve their efficiency and reduce(67). WLANs can also enable entirely new business processes. To cite but one example, hospitals are using WLAN-enabled point-of-care applications to reduce errors and improve overall(68) care. WLAN management solutions provide a variety of other benefits can be substantial but difficult to measure. For example, they can protect corporate data by preventing(69) through rogue access points. They help control salary costs, by allowing IT staffs to manage larger networks without adding staff. And they can improve overall network management by integrating with customers' existing systems, such as Open View and UniCenter. Fortunately, it isn't necessary to measure these benefits to justify investing in WLAN management solutions, which can quickly pay for themselves simply by minimizing time-consuming(70)and administrative chores.
A. chores
B. chains
C. changes
D. links
