D.need【答案】ACDBCACDCDBDDBA【解析】文章讲述黄旭华因目睹国家困境立志强国，隐姓埋名研发核潜艇，获诸多荣誉，其精神激励后人。1.A考查不定冠词的用法。不定冠词a/an用于泛指，a用于辅音音素开头的单词前，an用于元音音素开头的单词前；the用于特指。这里表示“作为一个孩子”，是泛指，且child以辅音音素/tʃ/开头，所以用a。2.C考查一般过去时。句意：他承诺用他的知识来保护中国。文章讲述的是过去的事情，这里描述的是HuangXuhua过去做出的承诺，所以用一般过去时，promise的过去式是promised。3.D考查decidetodosth.的用法，意为“决定做某事”，是固定搭配。句意：在20世纪50年代，中国决定建造核潜艇。根据decidetodosth.的结构，这里要用tobuild。4.B考查连词的用法。when表示“当……时候”；because表示“因为”；unless表示“除非”；if表示“如果”。句意：这非常困难，因为没有先进的技术和足够的材料。后一句“没有先进的技术和足够的材料”是“这非常困难”的原因，所以用because引导原因状语从句。5.C考查stopdoingsth.与stoptodosth.的区别。stopdoingsth.表示“停止正在做的事情”；stoptodosth.表示“停下来去做另一件事”。句意：他们甚至停止和家人交谈。这里指为了保密项目，他们停止和家人交谈，所以用stoptalking。6.A考查“keep+宾语+形容词”结构，意为“使……保持某种状态”。safe是形容词“安全的”；safety是名词“安全”；safely是副词“安全地”；safer是safe的比较级。句意：使这个项目安全。根据keep+宾语+形容词结构，这里用形容词safe。7.C考查介词的用法。for+一段时间，表示动作或状态持续的时间长度；on用于具体某一天；in用于年、月、季节等；at用于具体时刻。句意：黄离开家乡，很长时间没有回去。alongtime是一段时间，所以用for。8.D考查few,little,much,many的用法。few修饰可数名词复数，表否定“几乎没有”；little修饰不可数名词，表否定“几乎没有”；much修饰不可数名词，“许多”；many修饰可数名词复数，“许多”。句意：这个团队面临许多问题。problems是可数名词复数，这里表示“许多问题”，所以用many。9.C考查连词的用法。and表并列“和”；but表转折“但是”；so表结果“所以”；or表选择“或者”。句意：他们不能向外国专家求助，所以他们使用像算盘和尺子这样简单的工具。前后句是因果关系，前因后果，所以用so。10.D考查thousand的用法。thousand前有具体数字时，用单数形式，如twothousand；thousandsof表示“成千上万的”。D句意：他们做了成千上万次实验。这里没有具体数字，所以用thousandsof。11.B考查other,another,others,theother的用法。other后接名词复数，泛指“其他的”；another表示“三者或三者以上中的另一个”；others相当于“other+名词复数”，泛指“其他的人或物”；theother表示“两者中的另一个”。句意：另一个巨大的挑战是使潜艇在水下保持稳定。这里表示众多挑战中的“另一个”，所以用another。12.D考查副词的用法。这里需要一个副词来修饰动词worked。perfect是形容词“完美的”；moreperfect是其比较级；moreperfectly是perfectly的比较级；perfectly是副词“完美地”。句意：在20世纪70年代，中国第一艘核潜艇完美地运行了！修饰动词worked要用副词perfectly，且无比较意味。13.D考查形容词最高级的用法。形容词最高级前一般要加the。high是原级“高的”；higher是比较级“更高的”；highest是最高级“最高的”。句意：他继续改进潜艇设计，并在2019年获得了最高荣誉——“共和国勋章”。“共和国勋章”是最高荣誉，所以用最高级thehighest。14.B考查物主代词的用法。we是主格“我们”；our是形容词性物主代词“我们的”，后接名词；ours是名词性物主代词，相当于“our+名词”；ourselves是反身代词“我们自己”。句意：今天，黄的故事教导我们要努力工作，勇敢面对困难，热爱我们的国家。这里修饰名词country要用形容词性物主代词our。15.A考查情态动词的用法。should表示“应该”，表建议；can表示“能，会”；must表示“必须”，语气较强；need表示“需要”。句意：年轻人应该以他为榜样，使中国更强大。这里是一种建议，年轻人“应该”以他为榜样，所以用should。Passage2LianPoandLinXiangruweretwoimportantpeopleintheStateofZhao.Lianwasabravegeneral,andLinwas___1_____excellentadvisor.Lianwasfamous___2____winningbattles(战役)andmakinghisenemiesscared.HeonceledtheZhaoarmytovictoryagainsttheStateofQi.Everyone___3____himforhisbravery.Lin,ontheotherhand,wascleverandknewhowtousewords___4_____problems.HeoncesavedtheHeshibifortheKingofZhaoandbecameatrustedadvisor.Buttherewasaproblem.LianfeltworriedafterLingota____5_____positionthanhim.Hethoughtheshouldbegivengreaterhonorbecauseof____6_____achievementsonthebattlefield,whileLinachievedsuccessjustthroughhisskillsinspeakinganddebating(辩论).____7_____,LianevenspokeillofLinbehindhisback.Lindidn’twantanytrouble,____8_____heavoided（避免）meetingLian.Hedidn’twanttoargueorfight.LianthoughthewaswinningbecauseitappearedthatLinwasscaredofhim.Lin’sfriends,however,wereworried____9___this.TheythoughtLinwastookindandweak.ButLinexplainedthathedidn’thavereasonstofightLian____10_____itwouldharmtheircountry.He___11___believedthatiftheypulledtogether,theStateofZhaowouldbecome_____12___
