B．planningC．natural D．formal解析：同义复现题。由上文中的explorenewaspectsoflife可知，所填词与explore(探索)在词义上相近，故选searching(寻找)。planning计划；natural自然的；formal正式的。答案：A2．A.progress B．experienceC．major D．opinion解析：上下文语境题。根据语境可知，此处指作者发现了朝更好的方向改变自己大学经历(experience)的东西。另外，第三段中的Ihadexperienced也给出了提示。progress进步；major专业；opinion观点。答案：B3．A.choose B．readC．learn D．create解析：下文语境题。后面一句提到作者的全家人及他所有的朋友都有听觉，因此他之前从没有想学(learn)手语的强烈愿望。另外，第四段中的Ionlylearnedhowto也给出了提示。choose选择；read阅读；create创造。答案：C4．A.official B．foreignC．body D．spoken解析：上下文语境题。既然作者和家人及朋友都有听觉，那么在作者与别人的所有交往中口语(spokenlanguages)已经足够了。officiallanguage官方语言；foreignlanguage外语；bodylanguage肢体语言。答案：D5．A.love B．concernC．goal D．request解析：下文语境题。由下文的内容尤其是最后一段中的“Now，Iappreciatethesilence...”可知，作者后来爱上了美式手语，但是刚开始的时候作者没有发现自己对它的热爱(love)。concern关注；goal目标；request请求。答案：A6．A.meeting B．tripC．story D．task解析：下文语境题。由空格后面的内容可知，作者开始讲事情的经过了，故选story(故事)。meeting会议；trip旅行；task任务。答案：C7．A.recorded B．performedC．recited D．discussed解析：上下文语境题。由空格前的watched(观看)和后面的thehandmovements(手部的动作)以及whatIsaw(我所看见的)可知，作者是在观看美式手语俱乐部的成员表演(perform)他们对一首歌的诠释。record记录；recite背诵；discuss讨论。答案：B8．A.idea B．amountC．dream D．reason解析：上下文语境题。根据语境可知，这里指的是无语言交流的想法(idea)。idea与前面的thehandmovements并列。amount数量；dream梦想；reason原因。答案：A9．A.disturbed B．supportedC．embarrassed D．attracted解析：下文语境题。下文提到作者参加了美式手语俱乐部的一次会议并在下一学期参加了美式手语学习班的课程，由此可以看出，这种手部的动作以及无语言交流的想法把作者给吸引(attract)住了。disturb打扰；support支持；embarrass使尴尬。答案：D10．A.end B．pastC．course D．distance解析：上文语境题。根据Ihadexperienced用的时态可知，它指的是作者过去的经历，故选past。inthepast过去，是固定搭配。intheend最后；inthecourse经常与of连用，意为“在……期间”；inthedistance在远处。答案：B11．A.showing B．actingC．saying D．wanting解析：下文语境题。由下文中的further以及最后一段中提到作者参加了美式手语学习班的课程可知，这种新颖让作者想要(want)了解更多。show展示；act表现；say说。答案：D12．A.exercise B．exploreC．express D．explain解析：上文复现题。由第一段第一句中的explore可知，此处应填explore，指作者感受到了进一步探索的必要。exercise练习；express表达；explain解释。答案：B13．A.print B．writeC．sign D．count解析：上下文语境题。因为作者是在学习美式手语(AmericanSignLanguage)，所以他就得学会如何打手势。这里是说那天作者只学会了如何用手势表示(sign)字母表中的字母。print印刷；write写作；count数数。答案：C14．A.slow B．steadyC．normal D．obvious解析：上文语境题。由前面的beingdiscouragedby(对……感到失望)可知，此处是说作者的进步缓慢(slow)。steady持续的；normal正常的；obvious明显的。答案：A15．A.chair B．sponsorC．attend D．organize解析：上下文语境题。虽然作者在学美式手语方面进步缓慢，但他还是感到很兴奋，因此他把出席那些会议并尽最大可能多学看作重要的事情。attendameeting出席会议，是固定搭配。另外，本段第一句中的dropinononeofASLclub’smeetings也给出了提示。chair主持；sponsor赞助；organize组织。答案：C16．A.missed B．passedC．gaveup D．registeredfor解析：下文语境题。后面讲的是课堂上的事情，由此可以推断出接下来的那个学期，作者参加了美式手语学习班的课程。registerfor注册，登记，是固定搭配，且符合此处的语境。miss错过；pass通过；giveup放弃。答案：D17．A.prohibited B．weledC．ignored D．repeated解析：上文语境题。由空格前面的theprofessorwasdeaf可知，在课堂上是禁止(prohibit)说话的。wele欢迎；ignore忽视；repeat重复。答案：A18．A.Lastly B．ThusC．Instead D．However解析：下文语境题。由后面主从句谓语动词的结构可知，此处用的是虚拟语气，也就是说所填词表示的是一种相反情况的假设，故应选instead(相反)。答案：C19．A.required B．causedC．allowed D．expected解析：上下文语境题。相反，如果有任何交谈的话，那会导致学生们学到的更少。causesb.todosth.导致某人做某事，是固定搭配，且符合此处的语境。require要求；allow允许；expect预料。答案：B20．A.easy B．popularC．quick D．new解析：同义复现题。由第三段最后一句中的thisnewness可知，对作者来说，这是一种新的(new)交流方法，而不是容易的(easy)、流行的(
