为了消磨时间，“我”买了报纸和巧克力，故选bought。2．A 由文章推断出，“我”走进了一家咖啡店，故应选went。3．A tositat作tables的后置定语，意为“可以在旁边就座的桌子”。4．C 按常理“我”应把报纸等放在桌子上，而不是“推到”或“拉到”桌子上，故应选put。5．C 由下文可知，回来时“我”发现他开始吃“我”的东西，说明他坐在旁边的座位上，故选sitting。6．B 用it指代前文中未知的人。7．D 头发应是被染成艳红色的，故应选colored。8．B 面对这样一个人，“我”不想惹麻烦，trouble合乎文意，为正确选项。9．C 由下文可知，“我”吃的是这个男孩正吃的巧克力，这引起了对方的某一反应。比较四个选项，再根据上下文，用名词surprise比较合乎当时的情形。10．B “a＋序数词＋名词”常用来表示“再一个，又一个”，与下文tookathirdpiece相呼应。11．A 根据文意可知那个男孩起身要走，故选择stood。12．B 男孩生气了，必定说了发泄的话，比较四个选项，wrong为最佳选择。13．B 男孩骂了“我”，导致大家都朝“我”看，而“我”不想与他争吵，可见“我”的反应与上文描述的气氛恰恰相反，故选择but构成转折关系。14．C 固定搭配makeamistake意为“犯了个错误”。15．B “我”在喝完咖啡准备离开时发现了自己的过错，故应选leave。Ⅱ.A本文讲述了沉迷网络游戏所引起的问题。16．C 词义猜测题。diversion意为“转移”，在文中意指人们通过虚拟世界来逃避现实，故选C。17．C 推理判断题。第二段通过三个年轻人的例子说明了网络游戏对年轻人的负面影响，故选C。18．D 推理判断题。根据SueHueiChen的研究，沉迷网络游戏的人缺少友谊和人际交往，故可推断增强个人的交往能力可以防止玩游戏上瘾。19．C 细节理解题。根据第二段最后一句可知答案。20．B 主旨大意题。全文讲述的是网游上瘾的问题，故B项最符合文意。B这是一篇科普类文章。作者向我们报道了关于人脑信息和电脑信息研究的最新突破，该技术目前正准备在病人身上应用。21．B 细节理解题。由第一段可以看出，BCI技术是科学家一直研究的tolinkthebrainwithcomputers技术，由此可知B项正确。C项有极大的干扰性。22．D 细节理解题。由第三段的Inthelaboratory,Tavellaoperatedthewheelchairjustbythinkingaboutmovinghisleftorrighthand.可知是说通过他的思维。故选D。23．C 事实排序题。由该段可知，信号从thescalp(头皮)发出后被aspecialcap接收，接着传到了acomputer，然后到轮椅，由此可知C项正确。24．B 细节理解题。最后一段Oneistestingwithrealpatients,soastoprovethatthisisatechnologytheycanbenefitfrom.中的they指的是patients，证明他们能从中获益，也就是对于他们是有用的(useful)，因此可知答案。25．C 主旨大意题。文章向我们介绍了瑞士BCI研究中心的一个新技术的工作原理，以及给残疾人带来的实惠。5
