sfollowingCOPPA,itistotallysafe”可知，人们认为遵循COPPA的网站可以确保他们上网的绝对安全，然而事实表明，这是错误的观念。15．选B写作意图题。通读全文可知，文章最后一句中的“italsocanbedangerousifyouarenotcareful”点明文章主旨，即告诫人们在上网时应该小心谨慎。语篇解读：本文是一篇说明文，主要介绍了在许多国家都很受欢迎的网络课程。16．选B后文“Butmostshowavideoof...takepartinonlineactivities.”提到大多数网络课程都是播放老师和学生在教室里的视频，这是网络课程的形式，所以此处应该是指出网络课程有多种形式，以引出下文。17．选D根据后文“SomeschoolsinSingapore,...blackboardsintheclassrooms.”可知，在新加坡的一些学校里，教室里用平板电脑和触摸屏代替书本和黑板，且新加坡的网络学习仅是本处填入句的一个例子，所以“世界各地都在测试其他类型的网络学习”衔接通顺，语意流畅。18．选G根据后文“Theteachersareintheirhomecountries...throughtheInternet.”可知，这些老师在自己的国家，通过互联网与韩国的教室相连，所以前句应该是说明韩国的学生可以向远在异国的老师学习英语。19．选F根据前文“Therobotiscontrolledby...willreplacerealteachers.”可知，机器人由老师控制，可以在教室里走动，与学生交谈。机器人老师不太可能取代真正的老师，所以“但就像在线学习环境一样，它们是有用的工具”承接上文，符合语境。20．选E该句上文提到，由于科技的发展，越来越多的教与学的方法被开发出来。下文提到，然而，有一件事是肯定的——现在是学生生涯中最有趣的时刻，所以“没有人知道未来的教室会是什么样子”承上启下，符合语境。第二部分语篇解读：本文是一篇说明文。文章介绍了如何识别网络攻击。21．选B根据前文“Cyber­attacksmaysoundlikesomethingthathappensonlyinHollywoodmovies.”可知，网络攻击可能听起来也许只会出现在好莱坞电影里，因此推断下文“ateamoftalentedHackersgatheredaroundcomputermonitorstryingtobreakintoasecurehankorgovernmentserver”是作者让读者想象(picture)的情境。故选B。22．选A根据下文“A__________attackinvolvesacyber­criminalsendingoutthousandsorevenmillionsoflinksandflies.”可知，在典型的网络攻击中网络罪犯发送数千甚至数百万个链接和文件，因此网络攻击是危险的(dangerous)。故选A。23．选B根据下文“attackinvolvesacyber­criminalsendingoutthousandsorevenmillionsoflinksandflies”可知，此处讲述了一个非常典型的网络攻击。historic“与历史有关的”；typical“典型的”；potential“潜在的”；specific“明确的”。故选B。24．选D根据下文“Somebodyalwaysdoes.”可知，网络攻击犯罪分子认为最终会有人打开病毒文件或页面，的确有人经常这么做。halfway“在中途”；originally“起初”；periodically“周期性地”；eventually“最终”。故选D。25．选D根据下文“aswellashowtopreventthemfromhappeninginthefirstplace”可推断，学会如何识别(recognize)网络攻击，防患于未然。故选D。26．选C根据下文“thisisn'talwaysthecaseKickers...eventheskillfulcomputer­users”可知，事实并不像很多人认为的那样，以为黑客受害者对保护数字安全的最佳做法一无所知，可是，虽然能够识别一些明显的骗局，但是有些攻击会让最精明的用户上当受骗。fearless“无所畏惧的”；soundless“无声的”；clueless“(对某事)不懂的”；careless“粗心大意的”。故选C。27．选B根据上下文语境可知，前后文是顺承关系。故选B。28．选D根据下文“So，it'suptoyoutobevigilant(警觉的)andprotectyourself.”可知，你必须提高警惕保护自己，因此推断此处表示访问了错误的网站，下载了感染(infected)了病毒的文件，故选D。29．选B根据上文“Soyouneedtolearntorecognizethesignsofcyber­attacks.”可知，首先识别账号或设备上的可疑(suspicious)行为，学会识别网络攻击的迹象，故选B。30．选A根据下文“somethingsmaybeobvioussuchasaccountpasswordchanges,othersaren'tsoeasytospot”可知，上下文是让步关系，应用while引导让步状语从句。故选A。31．选C根据下文“Sometimes,thedataareevenreal,butthehackermayhaveinsertedafewlinesofcodethatcanalsoinfectyourcomputer.”可知，黑客插入了几行代码，它们也能感染你的电脑，因此推断邮件已经泄露。guarantee“保证”；assess“评估”；leak“泄露”；compose“组成”。故选C。32．选C根据上文“Youshould
