參考答案一、單項選擇（共10小題，滿分20分）1、D【解析】【詳解】句意：讓我們一起來思考這個問題。一定有辦法解決它。考查情態動詞。needn’t不必；haveto不得不；mustn’t禁止；must必須、一定。根據“Let’sthinkabouttheproblemtogether.

”和“awaytosolve(解決)

it”可知，應該是“一定”會有辦法解決。故選D。2、C【解析】【詳解】句意：——怎么制作風箏？——你需要用木棍和紙來制作它。考查非謂語動詞。此處使用todo不定式作目的狀語，故選C。3、A【解析】【詳解】句意：四周很安靜，我們只能聽到雨水打在窗戶上的聲音。考查名詞辨析。sound聲音；noise噪音；voice嗓音。根據“the...oftherainhittingthewindows”可知，是雨水打在窗戶上的聲音。故選A。4、C【解析】【詳解】句意：多么令人興奮的消息啊！下周我們將有一次春游。考查感嘆句。根據“excitingnews”可知，其為名詞短語，且news“消息”為不可數名詞，此時應用感嘆句句型“What+形容詞+不可數名詞+主謂”。故選C。5、B【解析】【詳解】句意：她過去常常在早上讀書，但現在她習慣了在晚上讀書。考查動詞短語。usedtodosth.過去常常做某事；beusedtodoing習慣做某事；beusedtodo被用來做某事。根據“usedto...inthemoring,butnowsheisusedto...atnight”可知是她過去在早上讀書，但是現在習慣于在晚上讀書，故第一個空用結構usedtodo，第二個空用beusedtodoing。故選B。6、B【解析】【詳解】句意：——你叔叔離開家鄉有多久了？——他離開將近20年了。考查特殊疑問句和現在完成時。第一個空后的leave“離開”是短暫性動詞，Howlong后面的動詞應該用延續性動作，所以選項C、D不正確；第二個空后的fornearlytwentyyears表示“持續了將近二十年”，時態應為現在完成時，應將短暫性動詞轉換為延續性動詞beaway，主語為He為第三人稱單數形式，結合現在完成時結構故為hasbeenaway。故選B。7、B【解析】【詳解】句意：貝蒂很聰明，她能自己解決這道難題。考查形容詞辨析。pretty漂亮的；smart聰明的；humorous幽默的。根據“shecansolvethedifficultproblembyherself.”可知貝蒂是聰明的。故選B。8、B【解析】【詳解】句意：——你為Sally的生日買了什么特別的東西嗎？——不是很特別。僅僅是一些花。考查復合不定代詞。something一般用于肯定句中；anything一般用于疑問句和否定句中；nothing沒有什么。本句是一般疑問句，用anything符合語境，故選B。9、B【解析】【詳解】句意：——你為演講比賽做好準備了嗎？——沒，還沒有。考查動詞短語。getsomethingtosb.把某物給某人；getreadyfor為……做準備，后可加名詞；makeyourselfto無此表達。根據“theSpeechCompetition”可知，是為比賽做準備。故選B。10、B【解析】【詳解】句意：李先生去昆明了。他去過這座城市3次了。這次他在昆明已經三天了。考查現在完成時。hasgoneto去了某地（沒回來）；hasbeento去過某地（回來了）；hasbeenin在某地。根據語境，第一空是“去了昆明”（沒回來），用hasgoneto；第二空是“去過昆明三次”，用hasbeento；第三空是“在昆明三天了”，用hasbeenin。故選B。二、完成句子（共5小題，滿分10分）11、Passmethatgreenruler【解析】【詳解】根據所給標點可知本句是祈使句，分析所給單詞可知，pass作謂語動詞，me作賓語；that指示代詞；green作定語修飾名詞ruler，thatgreenruler作賓語。故填Passmethatgreenruler“把那把綠色的尺子遞給我”。12、Iwasdoing/washingthedishes(whentherainstormcame)./Iwasdoinghousework(whentherainstormcame)【解析】【詳解】根據問句“Whatwereyoudoingwhentherainstormcame?”可知，此處是在回答“(當暴風雨來臨的時候)我正在洗碗/做家務活”，時態為過去進行時，主語為“I”，結構為“was+現在分詞”；do/washthedishes/dohousework“洗碗/做家務活”；whentherainstormcame“當暴風雨來臨的時候”。故填Iwasdoing/washingthedishes(whentherainstormcame)./Iwasdoinghousework(whentherainstormcame)。13、keptintouchwith【解析】【詳解】句意：我已經很久沒有和杰克保持聯系了。keepintouchwith“和……保持聯系”，結合空前的haven’t和foralongtime，可知句子是現在完成時，此時動詞keep要用過去分詞kept，與haven’t構成現在完成時的謂語結構。故填keptintouchwith。14、WhatshouldIdo【解析】【詳解】根據圖片以及“IhadafightwithJudy.”和“Youshouldtalkwithher.”可知，此處應問“我應該做什么”。what“什么”；should“應該”。故填WhatshouldIdo。15、handsome【解析】【詳解】句意：我認為李華的弟弟/哥哥是一個英俊的男孩。boy男孩，名詞需用形容詞修飾；根據boy和漢語提示，handsome用于男生表示“英俊的”，符合語境，故填handsome。三、補全對話（10分）16、1.C2.E3.F4.A5.D【解析】【導語】本對話是售票人員和乘客Julia關于買票的對話。【1題詳解】根據回答“IwanttobookatickettoDali.”可知，我想訂一張去大理的票。再根據全文可知，本對話是售票人員與Julia的對話，所以該空是服務用語，C選項“我能幫你嗎？”符合情景。故選C。【2題詳解】根據回答“Yes.”可知，該空是一般疑問句，且是Julia說的話，E選項“你還有票嗎？”符合情景。故選E。【3題詳解】根據回答“Atseveno’clockthisevening.”可知，在今晚七點，所以該句詢問時間，F選項“你什么時候坐火車？”符合情景。故選F。【4題詳解】根據回答“Ipreferthesoftsleeper.”可知，我更喜歡軟臥，所以該空與詢問臥鋪類型有關，A選項“你想要哪種臥鋪？”符合情景。故選A。【5題詳解】根據回答“Itis390yuan.”可知，它390元，所以該空詢問價格，D選項“這票多少錢？”符合情景。故選D。四、閱讀理解（40分）17、1.A2.C3.B4.C5.B【解析】【導語】本文介紹了一個叫《玩具總動員》的電視節目，人們用樂高積木修建一個真正的房子，但后因沒有買主而被拆掉，樂高積木捐給了慈善機構。【1題詳解】細節理解題。根據“TheyweretheretohelpJamesMaytobuildahouse.”可知，很多人一早來到鄉下等待是為了幫助修建房子。故選A。【2題詳解】細節理解題。根據“ItwasaLegohouse.1,200peopleused3.3millionLegotoybrickstomakearealhouse.”可知，這個樂高房子用了330萬塊樂高積木修建。故選C。【3題詳解】細節理解題。根據“AfewyearsagoinAugust...TheyweretheretohelpJamesMaytobuildahouse.Butitwasnotacommonhouse.ItwasaLegohouse.1,200peopleused3.3millionLegotoybrickstomakearealhouse.”可知，首先人們用樂高積木修建一個真正的房子，即②；根據“ThepeoplefinishedbuildingthehouseonSeptember17th”可知，9月17日，人們完成了房子的修建，即④；根據“SoonSeptember22nd,theystartedtotakethehousetopieces.”可知，9月22日，人們開始把積木房子拆成碎片，即①；根據“TheTVcompanydonated（捐獻）thethreemillionLegopiecestoacharity（慈善機構）forchildren.”可知，電視公司將樂高積木捐給了慈善機構，即③。因此事情發生的順序為②④①③。故選B。【4題詳解】細節理解題。根據“HestartedaFacebookpageandaskedotherpeopletobuyit,butnobodywantedit.”可知，James沒能為樂高房子找到一個買主。故選C。【5題詳解】推理判斷題。通讀全文可知，本文介紹了一個叫《玩具總動員》的電視節目，人們用樂高積木修建一個真正的房子，但后因沒有買主而被拆掉，樂高積木捐給了慈善機構。因此最有可能在雜志上找到該文章。故選B。18、1.A2.A3.C4.B5.C【解析】【導語】本文主要是在呼吁志愿者幫助三個不同的組織。【1題詳解】細節理解題。根據“Youneedtobefriendlyandcheerful—thechildrenaresickandyouneedtocheerthemup.”可知，如果你和孩子們相處得很好，你可以去SunnyviewChildren’sHospital。故選A。【2題詳解】細節理解題。根據“WeneedtwopeopletovolunteeryourtimeatSunnyviewChildren’sHospital...PleasecallMr.Chanat555-9879.Thanks!”可知，陳先生在SunnyviewChildren’sHospital工作。故選A。【3題詳解】細節理解題。根據“Areyouinterestedinrepairingthings?...CallHomeLoveat555-4663.”可知，如果你喜歡修理東西，你可以撥打電話555-4663。故選C。【4題詳解】細節理解題。根據“WeneedpeoplewhoarestrongandcanhelpcleanupBlueWaterBeach.Wedon’twanttoputoffthisjobtillsummer.Weneedyourhelptocollectandcarrygarbage.”可知，可以在BlueWaterBeach撿垃圾和搬運垃圾。故選B。【5題詳解】細節理解題。根據“WeneedpeoplewhoarestrongandcanhelpcleanupBlueWaterBeach...IfyouareavailableforsixhoursthisSaturday,callusat555-6668or555-6669.”可知，如果想在海灘上做志愿者，需要花費6個小時。故選C。19、1.C2.A3.C4.A5.B【解析】【導語】本文主要描述了一些學生對中國發展的看法。【1題詳解】細節理解題。根據第一段的“Herearesomeoftheiranswersonline.”可知以下是他們在網上的一些答案。因此是在互聯網上。故選C。【2題詳解】詞句猜測題。根據第二段的“Inthe5Ghall,Iwasimpressedbyhowquicklypeoplecoulddownload(下載)videos.Ittookjustseconds.Itwasamazing!”可知在5G大廳，人們下載視頻的速度只用了幾秒鐘，所以太神奇了！因此可推知是感覺驚訝的。故選A。【3題詳解】細節理解題。根據第三段的“Inthe2010s,thespeedofChina’sfastesttrainshadrisento50kmperhour.”可知在2010年代，中國最快的列車速度已經上升到每小時50公里。故選C。【4題詳解】細節理解題。根據第二段的“Inthe5Ghall,Iwasi
