因“这孩子躲在了床底下或柜子里”与“没有救出孩子”是因果关系，引导原因状语从句，用because。2．dead3．a 固定搭配：catchaglimpseof看见。4．they 指代他那个社区的children。5．which 引导定语从句并在从句中作with的宾语，先行词是theoxygenmask。6．in 表示“用”某种语言，用介词in。7．other 表示“另外的，别的”，作定语，用other。8．saves/hassaved 指客观事实，可用一般现在时；也可理解为告知性演讲“已经挽救了”许多生命，因此，也可用现在完成时。9．Fortunately 修饰后面的整个句子，作状语，用副词。10．taught 过去分词作定语；由by可知此处表示被动含义。Ⅱ.A文章向我们介绍了一种新型的机器人，它能在身体受损的情况下进行自我调节、自我修复。11．C 细节理解题。由第三段的…cansenseinjurytoitselfandadapt可知，这台机器人能够自己发现问题，并进行自动修复。12．D 细节理解题。由该段的Fromtheinformationitcollects,therobotcreatesitsownprogramsthatallowittoadapttodifferentsituations.可知，随后所举的例子就是为了说明其能够搜集信息、适应新的环境变化。13．C 词义猜测题。下文把这种类型的机器人比作starfish，并把它的性能和真正的starfish进行了比较：arealstarfishismuchbetterthanourrobotatrecoveringfrominjury，由此可以得出答案。14．A 细节理解题。用排除法。最后一段告诉我们，机器人不能和真的海星(starfish)一样长出新腿，故排除C；由最后一段前三句话可知：科学家正在寻找地方来试验这种机器人，也就是说还没有在海底使用，所以D项错误；由倒数第二段的最后一句话可以看出，这种机器人具有自我修复功能，即使是在一条腿受损的情况下，用三条腿也能走路，故B项错误。15．B 主旨大意题。文章向我们介绍了最近研发出来的一款智能机器人，其独特之处在于能够在部件损坏的情况下进行自我诊断、自我修复。由此可以看出B项最能概括全文。B作者为了照顾自己的奶奶(姥姥)，不得不放弃了继续在大学深造的机会。在忙碌的生活中，作者依然坚守着自己当初上大学的梦想，用21年的时间获得了大学学位。16．C 细节理解题。由第一段的aimingatalegalcareeranddreamingofsittingonaSupremeCourtbenchsomewhere可以看出，作者当初上哈佛大学的目的是：学法律、当法官。由此可以确定答案。17．D 细节理解题。第二段告诉我们，作者的奶奶(姥姥)得了癌症，作者withdrawfromcollegetocareforher，即：退学照顾奶奶(姥姥)。18．A 推理判断题。第四段告诉我们作者很忙碌(howfullyoccupiedIbecame)，第五段wantedmetostayhomewiththem这一情景告诉我们作者很幸福。19．B 推理判断题。文章最后一段告诉我们：任何东西的获得不是一天而成的，而是一个漫长的过程。最后一句话做了进一步的总结：littlestepsadduptobigdreams。这一意思和B项正好相符。20．A 推理判断题。作者有一个梦想，但在离梦想越来越近的时候，她选择了退学照顾自己生病的奶奶(姥姥)，同时她还收养了孩子，这都表明她很有爱心(caring)。与此同时，她在忙碌中没有忘记自己的梦想，用21年的时间获得了大学学位，由此可以看出作者意志很坚定(determined)。6\nⅢ.Onepossibleversion：Microblog_has_become_part_of_our_life.Itisveryconvenientforpeopletoexpresstheirfeelingsinstantlyatanytime.Besides,itprovidesachanceforpeopletoreleasetheirinnerstress.Byshowingtheirheartfeltemotionsonthemicroblog,theirfriendsmayalsoknowabouttheirconditionandcanoffertimelyresponse.However,microblogcanalsobepotentiallydangerousasitmaygiveawaypeople'sprivacyandothersignificantinformation.Allinall,microblogprovidesuswithsomeconcernsaswellasemotionalcomfortandlargequantitiesofinformation,soweshouldbecarefulwhileusingit.6
