参考答案及详解
1. C) 根据上下文，此空应该为介词，故选项A和B可被排除，因为它们后边 不能直接跟名词短语。根据句义，选项C为正确答案。
2. D) 根据语义线索(报纸有一个基本目的就是以最快速度从新闻来源处得到新闻)可知选项D为正确答案。
3. C) 根据语义线索选项C know 为正确答案。
4. B) 此题涉及other, another 两词的用法。Other可以单独使用也可以和定冠词the一起使用，other一般用来修饰表示不确定所指的复数可数名词，意为“其他”;the other用来指代或修饰特定范围内的第二者或第三者等，不合适。Another一般修饰可数名词单数，不合适One another是相互代词，不能作限定词。综上，根据语法线索，选项B为正确答案。
5. A) 根据上下文，该句句义有转折，故表示转折意义的关系副词选项A However为正确答案。其它三词：and为表示并列关系的并列therefore和so为表示因果关系的关系副词。
6. D) 根据上下文，报纸报道新闻应该发展更新更快的`通讯方式，可知其目的是为提高速度从而提高效率。故选项D为正确答案。
7. C) 此题可用排除法。根据语义线索(今天印刷的和人们阅读的报纸比以往任何时候都多)可将A，B和D排除。
8. D) 此题涉及动词keep的用法。动词keep后可接复杂宾语结构，即宾语+宾语补语的结构。形容词，?ed分词，ing分词等都可作宾补。其中，ed分词表示被动含义;ing分词表示主动含义。此句句义为“除了使读者知悉最新的新闻外 … ”，因此根据语法线索，含有被动意义的选项D为正确答案。
9. B) 根据句义可知此空应使用意为“通过”的介词。故选项B through 为正确答案。
10. B) 根据上下文可推断此句大概句义为“报纸通过广告维持它们的存在”，故选项B existence“存在”为正确答案。
11. C) 根据上下句句义可以推断，报纸不是通过出售其本身所得来维持其生存，而是通过刊登广告的收入来维持其生存，并且对于大多数的报纸来说主要的经费来源是商业广告，而不是出售报纸，因此可以猜测出报纸的售价不能涵盖其制作印刷成本，因此选项C为正确答案。其它三项意义不符。
12. A) 根据上句可推断此句的答案只能从A、B两项之间产生。Origin意为“起源，根源”不合适。故选项A source“来源”为正确答案。13. C) 根据此句义“这(报纸对广告商的价值)是以报纸的发行量来衡量” 及上下文可推断此空应填动词的被动形式，故选项C为正确案。14. B) 选项B为?ed分词作后置定语。
15. D) 根据词汇线索和语义线索可知，此处需要使用介词about，表示“关于社区、国家和世界的信息”。
