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
