B．planningC．natural D．formal解析：同義復(fù)現(xiàn)題。由上文中的explorenewaspectsoflife可知，所填詞與explore(探索)在詞義上相近，故選searching(尋找)。planning計劃；natural自然的；formal正式的。答案：A2．A.progress B．experienceC．major D．opinion解析：上下文語境題。根據(jù)語境可知，此處指作者發(fā)現(xiàn)了朝更好的方向改變自己大學(xué)經(jīng)歷(experience)的東西。另外，第三段中的Ihadexperienced也給出了提示。progress進(jìn)步；major專業(yè)；opinion觀點。答案：B3．A.choose B．readC．learn D．create解析：下文語境題。后面一句提到作者的全家人及他所有的朋友都有聽覺，因此他之前從沒有想學(xué)(learn)手語的強(qiáng)烈愿望。另外，第四段中的Ionlylearnedhowto也給出了提示。choose選擇；read閱讀；create創(chuàng)造。答案：C4．A.official B．foreignC．body D．spoken解析：上下文語境題。既然作者和家人及朋友都有聽覺，那么在作者與別人的所有交往中口語(spokenlanguages)已經(jīng)足夠了。officiallanguage官方語言；foreignlanguage外語；bodylanguage肢體語言。答案：D5．A.love B．concernC．goal D．request解析：下文語境題。由下文的內(nèi)容尤其是最后一段中的“Now，Iappreciatethesilence...”可知，作者后來愛上了美式手語，但是剛開始的時候作者沒有發(fā)現(xiàn)自己對它的熱愛(love)。concern關(guān)注；goal目標(biāo)；request請求。答案：A6．A.meeting B．tripC．story D．task解析：下文語境題。由空格后面的內(nèi)容可知，作者開始講事情的經(jīng)過了，故選story(故事)。meeting會議；trip旅行；task任務(wù)。答案：C7．A.recorded B．performedC．recited D．discussed解析：上下文語境題。由空格前的watched(觀看)和后面的thehandmovements(手部的動作)以及whatIsaw(我所看見的)可知，作者是在觀看美式手語俱樂部的成員表演(perform)他們對一首歌的詮釋。record記錄；recite背誦；discuss討論。答案：B8．A.idea B．a(chǎn)mountC．dream D．reason解析：上下文語境題。根據(jù)語境可知，這里指的是無語言交流的想法(idea)。idea與前面的thehandmovements并列。amount數(shù)量；dream夢想；reason原因。答案：A9．A.disturbed B．supportedC．embarrassed D．a(chǎn)ttracted解析：下文語境題。下文提到作者參加了美式手語俱樂部的一次會議并在下一學(xué)期參加了美式手語學(xué)習(xí)班的課程，由此可以看出，這種手部的動作以及無語言交流的想法把作者給吸引(attract)住了。disturb打擾；support支持；embarrass使尷尬。答案：D10．A.end B．pastC．course D．distance解析：上文語境題。根據(jù)Ihadexperienced用的時態(tài)可知，它指的是作者過去的經(jīng)歷，故選past。inthepast過去，是固定搭配。intheend最后；inthecourse經(jīng)常與of連用，意為“在……期間”；inthedistance在遠(yuǎn)處。答案：B11．A.showing B．a(chǎn)ctingC．saying D．wanting解析：下文語境題。由下文中的further以及最后一段中提到作者參加了美式手語學(xué)習(xí)班的課程可知，這種新穎讓作者想要(want)了解更多。show展示；act表現(xiàn)；say說。答案：D12．A.exercise B．exploreC．express D．explain解析：上文復(fù)現(xiàn)題。由第一段第一句中的explore可知，此處應(yīng)填explore，指作者感受到了進(jìn)一步探索的必要。exercise練習(xí)；express表達(dá)；explain解釋。答案：B13．A.print B．writeC．sign D．count解析：上下文語境題。因為作者是在學(xué)習(xí)美式手語(AmericanSignLanguage)，所以他就得學(xué)會如何打手勢。這里是說那天作者只學(xué)會了如何用手勢表示(sign)字母表中的字母。print印刷；write寫作；count數(shù)數(shù)。答案：C14．A.slow B．steadyC．normal D．obvious解析：上文語境題。由前面的beingdiscouragedby(對……感到失望)可知，此處是說作者的進(jìn)步緩慢(slow)。steady持續(xù)的；normal正常的；obvious明顯的。答案：A15．A.chair B．sponsorC．a(chǎn)ttend D．organize解析：上下文語境題。雖然作者在學(xué)美式手語方面進(jìn)步緩慢，但他還是感到很興奮，因此他把出席那些會議并盡最大可能多學(xué)看作重要的事情。attendameeting出席會議，是固定搭配。另外，本段第一句中的dropinononeofASLclub’smeetings也給出了提示。chair主持；sponsor贊助；organize組織。答案：C16．A.missed B．passedC．gaveup D．registeredfor解析：下文語境題。后面講的是課堂上的事情，由此可以推斷出接下來的那個學(xué)期，作者參加了美式手語學(xué)習(xí)班的課程。registerfor注冊，登記，是固定搭配，且符合此處的語境。miss錯過；pass通過；giveup放棄。答案：D17．A.prohibited B．weledC．ignored D．repeated解析：上文語境題。由空格前面的theprofessorwasdeaf可知，在課堂上是禁止(prohibit)說話的。wele歡迎；ignore忽視；repeat重復(fù)。答案：A18．A.Lastly B．ThusC．Instead D．However解析：下文語境題。由后面主從句謂語動詞的結(jié)構(gòu)可知，此處用的是虛擬語氣，也就是說所填詞表示的是一種相反情況的假設(shè)，故應(yīng)選instead(相反)。答案：C19．A.required B．causedC．a(chǎn)llowed D．expected解析：上下文語境題。相反，如果有任何交談的話，那會導(dǎo)致學(xué)生們學(xué)到的更少。causesb.todosth.導(dǎo)致某人做某事，是固定搭配，且符合此處的語境。require要求；allow允許；expect預(yù)料。答案：B20．A.easy B．popularC．quick D．new解析：同義復(fù)現(xiàn)題。由第三段最后一句中的thisnewness可知，對作者來說，這是一種新的(new)交流方法，而不是容易的(easy)、流行的(
