8．winners9.awake10.illness【详解】1．句意：迪克决定通过少吃和多做运动来减肥。本题考查固定短语。短语：loseweight减肥。根据前面的lose是动词后面应该接名词，提示词weigh是动词“称…重量”，应该用名词重量，故填weight。2．句意：杰克逊在那么短的时间内解决这个问题有困难。本题考查固定搭配。havedifficultlyindoingsth.做某事有困难，根据所给单词solve是动词解决，动名词形式是solving，故填solving。3．句意：中国比加拿大拥挤的多。本题考查形容词比较级。根据后面的than提示可知本题应该是比较级，前面的alot是多的意思，用于比较级前，加强语气，morethan是比…多，根据常识可知中国要比加拿大拥挤，故填morecrowded。4．句意：教育孩子是一种帮助拯救熊猫的方式。本题考查动名词做主语。根据提示词teach是动词，动词不能直接做主语，要用动名词的形式，后面的panda是名词前面用动词save，故填Teachingsave。5．句意：现在处于危险中的野生动物需要我们的保护。本题考查名词。所给词protect是保护的意思，空前面的our是形容词性物主代词，后面要加名词，protection是名词形式的保护，故填protection。6．句意：我认为使你强壮的最简单的方法之一就是多锻炼。本题考查形容词最高级。oneof+the+形容词最高级，是“最…之一”的意思，easy的最高级形式是easiest，故填easiest。7．句意：爱迪生是世界上最伟大的发明家之一。本题考查固定搭配。根据常识我们知道爱迪生是发明家，根据提示词invent是动词发明、创造，表示人的名词是inventor，根据前面的oneof后面接可数名词复数，故填inventors。8．句意：屠呦呦是2015年诺贝尔奖的获得者之一，我们都以她为骄傲。本题考查固定搭配。根据句子结构oneof后面接名词复数，表示…之一，win是动词，名词是winner，名词复数是winners，故填winners。9.句意：我进来时婴儿醒着。根据空前的系动词was可知，空处应该用形容词作表语，wake的形容词形式是awake，意为醒着的。故填awake。10.句意：他父亲因病看起来很苍老。“his”在本句中是形容词性物主代词，后接名词；“ill”是形容词，表示“生病的”，其名词形式为“illness疾病”，故填illness。二、完成句子，每空一词。11．这头大象比这只大熊猫重很多倍。Thiselephant________________________________________thanthispanda.12．科学家们说现在有不到2,000只大熊猫生活在森林里。Scientistssaytherearenow____________________2,000pandas__________intheforests.13．那些幼崽经常死于疾病，不会活太长时间。Thebabiesoften______________________________anddonotliveverylong.14．大熊猫越来越少的另一个原因就是人们砍伐树木。Anotherreasonfor_____________________pandasisthatpeopleare_____________thetrees.15．为了保护野生大熊猫，政府正在建立自然公园。Inordertoprotectpandasinthewild,thegovernmentis__________________natureparks.16．很多野生动物处于极度危险中。Manywildanimalsare______________________________.17．上个月他的祖父死于一场交通事故。Lastmonthhisgrandfather________________atrafficaccident.18．我们大约在操场上待了两个小时。Westayedfortwohours________________ontheplayground.19．这些礼物对我来说很特殊。Thesepresents________________________________me.20．因为他正在想事情，没有看路，所以他撞了墙。Ashewasthinkingandnotlooking,he________________awall.【答案】11．weighs

into【详解】11．本题考查比较级。短语：morethan超过；manytimes许多倍。本句是一个陈述事实的句子，用一般现在时，主语thiselephant是第三人称单数，所以weigh重量也用第三人称单数形式weighs，故填weighsmanytimesmore。12．本题考查比较级以及现在分词。fewerthan后面接可数名词，根据2000pandas是名词复数，是可数名词所以前面要用fewerthan。根据空前面的therearenow可知这句话用现在进行时，句中含有therebe的现在进行时，由there+be动词+sth.+动词的现在分词，所以后面的生活live用现在分词living，故填fewerthanliving。13．本题考查固定短语。dieof死于…（直接原因），熊猫宝宝死于疾病是直接原因用dieof，根据题干可知本题用的一般现在时，babies是复数，后面的谓语动词要用动词原形，illness是疾病的名词，死于…后面加名词，故填dieofillness。14．本题考查固定短语。fewerandfewer越来越少，修饰可数名词复数。cutdown砍伐，题干中that从句中主语是people，根据后面的are可知是人们正在砍树，用进行时，故填fewerandfewercuttingdown。15．本题考查固定短语。短语：setup建立，根据句意汉语提示可知是正在建立用现在进行时，主语是可数名词单数，结构是is+动词ing，故填settingup。16．本题考查固定短语。短语：indanger处于危险中。根据空前面的be动词are可知此处是指一种状态，处于危险中用固定短语indanger，极度危险在名词danger前加形容词great，故填ingreatdanger。17.根据中英文对照可知，英文表达中缺少“死于”的英语表达，死于dieof/from，在句中作谓语；dieof主要用于指疾病、衰老等自身的原因造成的死亡，diefrom主要用于指环境、事故等外部原因造成的死亡，根据空后的atrafficaccident可知，此处指事故造成的死亡，应该用diefrom，根据Lastmonth可知本句为一般过去时，动词应该用过去式diedfrom。故填died；from。18.根据中英对照，可知这里缺少“大约”这一表达，短语orso，意为“大约”。故填orso。19.根据中英文对照可知，缺少“对……很特殊”。bespecialto表示“对……是特别的”，主语为“Thesepresents”，be动词用are；very“非常，很”，副词，放在形容词前表示程度。故填are；very；special；to。20.“撞到”可用walkinto表示，根据“Ashewasthinkingandnotlooking”可知，动作发生在过去，应使用过去式，故填walked；into。能力提升一、单项选择21．Hehadtobeinhospitalforsomedaysbecauseofhis.A．illness B．business C．trip D．birthday【答案】A【详解】句意：由于生病，他不得不在医院住了几天。考查名词辨析。illness病；business生意；trip旅行；birthday生日。根据“Hehadtobeinhospital”可知是因为生病才要住院。故选A。22．________30workerswillgotoworkinthatcompany.A．Other B．Others C．Another D．Theothers【答案】C【详解】句意：另外30名工人将去那家公司工作。考查不定代词辨析。Other其他的，表泛指；Others其他的，相当于“other+名词”，表泛指；Another另外的，表泛指；Theothers其他的，相当于“theother+名词”，表特指。由于题干中的30位员工没有特指，排除D；空格后有名词，排除B；“数词+other+名词复数=another+数词+名词复数”为固定结构，故选C。23．Inordertohelppandasmorebabies,scientistsaredoingalotofresearch.A．prepare B．imagine C．produce D．receive【答案】C【详解】句意：为了帮助大熊猫生育更多的宝宝，科学家们正在做大量的研究。本题考查动词词义辨析。短语：inorderto为了。Aprepare意为“准备”；Bimagine意为“想象”；Cproduce意为“生育”；Dreceive意为“收到”。根据句意可知是帮助大熊猫生育更多的宝宝，故选C。24．We′reall________themathexam.A．preparingat B．readyat C．preparingfor D．getreadyfor【答案】C【详解】句意：我们都在准备数学考试。考查动词短语。preparingat错误搭配；readyat错误搭配；preparingfor为……做准备；getreadyfor为……做准备。根据“We′re...”可知设空处不能用动词原形，要用动词的现在分词形式与空前be动词构成现在进行时。故选C。25．Theplayerransofastthathewhilerunning.A．fallsover B．fellover C．felloff D．fallsoff【答案】B【详解】句意：那个运动员跑得很快，以致于跑的时候摔倒了。考查动词短语辨析。fallover摔倒；falloff从……掉下来；由“ran”可知用一般过去时；根据“whilerunning”可知，跑步时运动员是摔倒了，故选B。26．HerunclecamebacktoChinafromAmericatovisithergrandparents________.A．eachtwoyears B．everytwoyears C．eachtwoyear D．everytwoyear【答案】B【详解】句意：她的叔叔每两年从美国回来一次，来看望她的祖父母。考查频度的表达。结合给出四个选项可知，空格处需填“每两年”的表达；英语中表达动作或事情发生的频率可以用“次数+a+时间计量单位（day/week/month/year...）”或“every+时间单位（twodays/twomonths/twoyears...）”，故选B。27．Theclothesintheotherstoreare______,but______asthoseinthisstore.A．muchcheaper;notasbetterB．farmorecheaper;notasbetterC．muchmorecheaper;notasgoodD．farcheaper;notasgood【答案】D【详解】句意：那家商店的衣服比这家商店的便宜，但不如这家商店的好。两者比较用比较级，表示“比……”需要注意的是第一空还涉及到比较级的修饰词，常用的是far/much+比较级；同级比较用as...as或notas／so...as，中间加形容词/副词的原级。故选D。28．Ourcountryistakingactionto______airpollution.A．cutdownB．cutupC．cutout D．cutoff【答案】A【详解】句意：我们的国家正在采取行动减少空气污染。cutdown减少；cutup切碎；cutout裁剪；cutoff切断。结合语境采取行动是为了“减少”污染，所以选A。29．—Wherewillyougothiswinterholiday?—IwillgotoThailand,butIcan’tdecide.A．quickly B．probably C．certainly D．immediately【答案】B【详解】句意：--你这个寒假将会去哪儿?--我可能会去泰国，但是我还不能决定。本题考查副词词义辨析。Aquickly意为“快速地”；Bprobably意为“可能”；Ccertainly意为“当然”；Dimmediately意为“立刻”。根据butIcan’tdecide.和词汇辨析，故选B。30．—Animalsareourfriends.Weshouldprotectthem.—________.A．Iagreewithyou. B．Sure,goahead.C．Itmustfun. D．Howexciting!【答案】A【详解】句意：动物是我们的朋友，我们应该保护它们。考查情景交际。Iagreewithyou.我同意你的看法；Sure,goahead.当然了，继续吧；Itmustfun.说法错误。Howexciting!太令人兴奋了。根据上文，动物是我们的朋友。我们应该保护它们。可知选A最符合语境。二、语法填空根据短文内容及括号中所给词语在空白处填人适当的单词，使文章通顺、完整。Dearsirandmadam,I’mwritingtotellyouaboutthe__31__（dangerous）tigersarefacing.Tigersarebigandstrong.Theycanrunfastbutonly__32__ashortwhile.Theyliveintheforest,butnowtheyare__33__（lose）theirlivingareas.That’s__34__peoplekeepcuttingdownforeststomakemorefarmlandandbuildmorehouses.Somehuntersaretryingtocatchthemtoget__35__（them）furandbones.Theysellthemformoney.Sothenumberoftigersisbecomingmuch__36__（small）.I’mfeelingverysorryforthat.Ithinkit’sreally__37__shamethatsomepeopletrytokilltigers.It’stimethatweshoulddosomething__38__（protect）tigers.Ifhumanscontinuetodestroytheforestandmakemoneythroughtigers’furorbones,therewillbeno__39__（remain）tigersinthenearfuture.Iadviseeveryonenottobuyanythingmadeoftigersfurorbones.Let’strytogethertoaskthegovernmenttohelpprotecttigers.Ihopeyoucan__40__（accept）myadviceandrequests!Yourssincerely,Simon【答案】31.danger
