14、。2B考查动词辨析。根据第一段可知，传统的电视时代即将结束。因此，这里应该是说电视正走向“iPod”时代。通过对四个词语的辨析(achieving取得，获得；approaching走近，靠近； finishing完成； arriving到达)可知，答案为approaching，故选B。3B考查动词辨析。write 写； download下载；read 读； remember记得。通读全文以及对“iPod”为大容量MP3播放器的理解可知，人们把他们喜欢的音乐下载到他们的“iPod”里面。故选B。4D考查介词辨析。由对上句now download their favorite music onto

15、 their iPod，的理解可知， downloading most of favorite programs_4_their computers.这里应为“onto”，即把体现了前后一致。 即观众很快就会把大多数他们喜爱的节目下载到他们的电脑上。故选D。5A考查形容词。live现场直播的；present目前的，在场的；past过去的；late迟的，晚的。通过后面的like news, sporting events and emergencies可知，这里应该是“现场直播”的意思。而live有“现场直播的”意思，故选A项。6C考查副词。通过对全文的理解以及对it is going to b

16、e almost like the iPod的理解可知，“尽管人们仍需要新闻、体育比赛和紧急事件等的现场直播，但iPod模式将日益兴起”。而greatly“很，非常”；harmfully“有害地”；hopefully“有希望地”，均不符合题意，只有C项increasingly“日益”才符合题意，故选C项。7B考查动词辨析。watch观看，看； look有意识地看；notice注意； see看见，看到。watch“观看，看”之意，相当于look at。通过对词句的理解可知，下载是为了以后观看，而空后的at这个词也给了暗示。故选B项。8A考查名词作定语。mainstream主流的； famous

17、著名的； important 重要的； wellknown知名的，出名的。Mainstream(主流的)符合本句“尽管电视的需求已经不再是英国的主流活动”。其他选项不符合题意。故选A。9A考查固定词组。sums of表示“许多”之意。由后面的单词“money”可知，前面应用修饰不可数名词的短语。故选A项。10C考查固定搭配。句意：英国广播公司、国际电视台和第四频道在技术上都投入了大量资金，使观众能够观看他们最喜欢的节目。enable sb.to do sth.为固定搭配，意为“使某人能够做某事”。分析可知选C项。11C考查介词辨析。根据句意可知，是在电脑上看人们喜欢的节目。因此选C项。12B考

18、查动词。containing 包含，包纳；including包括(部分与整体)；naming命名；calling叫，认为，通电话。依据本段可知，不光是评论家提出了警告，而且也包括一些互联网服务提供商。由此可知答案为including；A项contain为“包含，包纳”，侧重容器的装下或成分上的含有，不符合题意；而C、D两项不符合文意，故选B项。13D考查固定搭配。under the stress of为 “在压力下”。此句意思为“在几百万人同一时间下载节目的压力下”，所以只有D项符合题意，故选D项。14A考查动词辨析。句意：但是瑟夫先生驳斥了这些警告，说批评家早在20年前就预言，当全世界的人们

19、开始大量使用网络时，网络将会崩溃。collapse崩溃；fall 下落，摔倒； rush 突袭，猛冲；jump跳过，快速移动。由本段的上一句可知，这里应为“collapse”，即“崩溃”。故选A项。15B考查动词辨析。develop“发展”； increase“增加，增长，增大(数目、数量、体积等)”； enhance“提高，提升”；常用于身份、声望等；enlarge“变大，扩大”。 由a million times可知，这里应为“增长了多少倍”，分析选项可知B项符合题意，故选B项。16B考查短语辨析。close to靠近，接近； far from远离，远非，不是； far away离远；ne

20、xt to接近，在近旁。通过对上文以及本句的理解可知，我们远没用尽这些容量。故选B项。17C考查形容词辨析。understandable意思为“可理解的”；miserable为“可怜的，不愉快的”；surprising为“令人惊奇的”；imaginable为“可想象的”。由“when they see huge amounts of information being moved around online在过去的30年里，它已经增长了一百万倍我们远远没有耗尽容量，”他说。“当他们看到大量的信息在网络上流动时，这种担心是可以理解的。”分析选项可知，这里选understandable比较符合文意

21、。故选C项。18D考查动词短语辨析。set out“陈述，展示，宣布”；take out“切除，拔出”；find out“找出，查明”；turn out“结果是。证明是，最终是”。句意：他展示了他对互联网未来的憧憬，。通过his vision for the future of the Internet理解，可知为setting out。故选D项。19A考查固定搭配。句意：展示了自己对互联网未来的憧憬，他希望能尽可能多地接触互联网。根据句意可知为“尽可能多的人”，people为可数名词的复数形式，因此要用many，故选A。20A考查固定搭配。句意：我希望地球上的每个人都能够连接到互联网， be

22、 able to do sth.是固定搭配，为“有能力做”，其他三项(easy容易的；happy快乐的，高兴的；willing愿意的)不符合文意，故选A项。.阅读理解 Some social networking websites help me keep in touch with my friends and family, find out what interesting events are going on and share photos within my social circle.
