參考答案一、單項選擇（共10小題，滿分20分）1、C【解析】【詳解】句意：薩莉現在在課堂上很活躍，但她以前是個很害羞的女孩。考查形容詞辨析。lazy懶惰的；silent沉默的；active積極的，活躍的。but前后表示轉折關系，but后“averyshygirl”表示她非常害羞，因此but前表示她不害羞，是活躍的，故選C。2、A【解析】【詳解】句意：他發現他們很難學好英語。考查固定句型。findit+形容詞+forsb.todosth.“發現對于某人來說做某事怎么樣”，故選A。3、C【解析】【詳解】句意：自從去年買了電腦，我就沒怎么鍛煉過。考查動詞時態。since引導的時間狀語從句，主句用現在完成時，從句用一般過去時，故選C。4、D【解析】【詳解】句意：他一生都在貧困地區生活，拯救了數百人的生命。考查形容詞辨析。valuable有價值的；poor窮的；own自己的；whole全部的，整個的。根據“Hehadspenthisentirelifeinpoorareas”可推出entire意為“全部的，整個的”，可用whole替換。故選D。5、C【解析】【詳解】句意：一些中國政府工作人員變成了網絡主播來幫助當地農民提高農產品的銷量。考查動詞辨析。return返回；realize意識到；improve改善、提高；provide提供。根據“AfewChinesegovernmentworkershaveturnedinto

livestreamers”可推出是幫助農民提高農產品的銷量。故選C。6、C【解析】【詳解】句意：——你看今天報紙上的最新消息了嗎？——是的，我看了。這是關于從南寧到香港的高速鐵路。考查形容詞辨析。newest最新的；fastest最快的；latest最近的。形容“最新的”不要用thenewest，這是中國人說英語的習慣，不地道，要用thelatest。故選C。7、B【解析】【詳解】句意：——你的小妹妹多大了？——她現在七歲了。今年九月份她就足夠大可以去學校。考查enough后置用法和形容詞辨析。enoughold錯誤表達；oldenough足夠大（年齡）；youngenough足夠年輕。根據“togotoschoolthisSeptember”可知，可以去上學，應該是年齡足夠大，故選B。8、C【解析】【詳解】句意：——瑪麗很了解她的丈夫嗎？——呃，她結婚15年了，但她仍然不知道自己嫁給了什么樣的男人。考查延續性動詞和動詞短語。根據“for15years”可知，第一空用延續性動詞，marry“結婚”對應的延續性動詞為bemarried，排除B和D；第二空處是定語從句，先行詞為“man”，表示她嫁給這個男人，marrysb意為“嫁給某人，與某人結婚”，且從句是一般過去時，所以空處用過去式married作謂語。故選C。9、A【解析】【詳解】句意：我不知道什么時候去見她，因為我忘了她的航班到達的時間。考查賓語從句。由“Ihavenoidea”可知此處缺少賓語，故應是賓語從句；由“Iforgetthearrivaltimeofherflight.”可知，此處表達時間，應用“when”來引導，故排除B、D兩項；特殊疑問詞引導的賓語從句遵從陳述語序原則，C項表達錯誤；此處使用“特殊疑問詞+不定式”作賓語。故選A。10、A【解析】【詳解】句意：不努力工作就不能指望獲獎。考查動詞辨析。expect期待，指望；afford買得起；invite邀請。根據“Youcan’t...towinaprizewithoutworkinghard.”可知，不努力就不能指望獲獎。故選A。二、完成句子（共5小題，滿分10分）11、①.has②.had③.for【解析】【詳解】句意：她兩天前買的這只狗。根據觀察可知原句的時態是一般過去時，變成同義句時，可改成現在完成時的句子，表示“她已經買了這只狗兩天了”。buy是短暫性動詞，不能與一段時間狀語連用，可改成have的現在完成時hashad；接一段時間用介詞for。故填has；had；for。12、①.showed②.his③.interest④.in【解析】【詳解】showone’sinterestin“對……感興趣”，根據“liked”可知，時態為一般過去時，動詞用過去式showed，his“他的”。故填showed；his；interest；in。13、(t)oothache【解析】【詳解】句意：如果你牙疼，請去看牙醫。根據“pleasegotoseeadentist”可知是牙痛，牙痛的英文表達為“haveatoothache”。故填(t)oothache。14、(s)eparately【解析】【詳解】句意：晚飯后，西方人通常分攤賬單并單獨支付餐費，因為自己支付餐費對每個人都公平。根據“Westernersusuallysplitthebill”可知西方人通常分攤賬單，所以此處應填副詞separately“分別地”修飾動詞“pay”。故填(s)eparately。15、seems【解析】【詳解】句意：我們一直期待的機會似乎失去了。分析句子可知，“we’vebeenlookingforwardto”是定語從句，修飾名詞“chance”；seem“似乎”，為謂語動詞；主句是陳述這件事，時態應用一般現在時，主語是單數名詞，謂語動詞用三單形式。故填seems。三、補全對話（10分）16、1.I’msorryIcan’t/I’mafraidIcan’t2.Ithinkyoushouldsaysorrytohim3.WhatshouldIdo4.Whynotsendhimamessage5.Thanks/Thanksforyouradvice【解析】【導語】本對話是關于A向John求助，以及John建議A發信息向哥哥道歉。【1題詳解】根據“canyouhelpmewithmyChinesethisevening?”和“Ihavetodomyhomework.”可知，對方請求幫助，但是有作業要做，所以不能答應。此處應是表示不答應對方的請求，故填I’msorryIcan’t/I’mafraidIcan’t。【2題詳解】根據“Ifoughtwithhimyesterdaymorning.”和“Isaidsorrytohim.Buthedidn’taccept.”可知，對方和哥哥打架了，對方道歉但是沒被接受。此處應是建議對方道歉，故填Ithinkyoushouldsaysorrytohim。【3題詳解】根據“Youcanwritehimaletter.”可知，建議對方寫信給哥哥。此處應是詢問該怎么辦，故填WhatshouldIdo。【4題詳解】根據“Goodidea.I’llsendhimamessagerightnow.”可知，接受建議，立刻給哥哥發信息。此處應是建議對方發信息給哥哥，且是疑問句，故填Whynotsendhimamessage。【5題詳解】根據“Ithinkyoushouldstudyharder.”和“I’llstudyhardertoimprovemyChinesefromnowon.”可知，對方建議努力學習，自己也表示會努力提升中文。此處應是表達感謝對方的建議，故填Thanks/Thanksforyouradvice。四、閱讀理解（40分）17、1.B2.A3.D4.D5.C【解析】【導語】本文是一篇應用文。Tommy自我介紹了家庭、性格、愛好和寫信的理由等信息。【1題詳解】細節理解題。根據第二段“Myfatherisanengineer.”可知，他的爸爸是一位工程師。故選B。【2題詳解】細節理解題。根據第三段“…joinedtheschoolOlympicMathsClubsincetwoyearsago.”可知，他兩年前加入奧林匹克數學俱樂部。故選A。【3題詳解】細節理解題。根據第二段“Iamtwelveyearsold.”可知，A選項錯誤；根據第二段“Therearefourmembersinmyfamily.”可知B選項錯誤；根據第二段“myelderbrother”可知，C選項錯誤；根據第四段“I’mactiveandoutgoing.”可知，D選項正確。故選D。【4題詳解】推理判斷題。根據第四段“Ialsolovemusic.I’mgoodatcommunicatingwithothers.”可知，并未提到喜歡音樂的原因。故選D。【5題詳解】推理判斷題。根據第一段“Iwanttostudyatyourschool”可知，他寫信的目的是想要在校長的學校就讀。故選C。18、1.E2.G3.A4.B5.D【解析】【導語】本文主要介紹了五個人的遇到的情況及相應的解決辦法。【1題詳解】根據“Brookisthinkingabouthowtoholdhisbirthdayparty.”可知Brook不知道怎樣辦派對，結合選項，選項E“你打算舉辦一個聚會嗎？你將如何邀請你的朋友？這篇文章將教你如何寫邀請函并邀請更多的朋友參加你的聚會。”與之對應。故選E。【2題詳解】根據“Edwinismakingaposteraboutthecarwithelectricity.Hewantstohelppeopleknowmoreaboutelectricitycars.”可知Edwin想要人們更多地了解電動汽車，結合選項，選項G“你喜歡汽油車還是電動汽車？這篇文章主要是關于電動汽車優點。”與之對應。故選G。【3題詳解】根據“SohewantstoknowaboutbodylanguageinJapan.”可知Joseph想要了解日本的肢體語言，結合選項，選項A“肢體語言交流很多。即使是同一個手勢在不同的國家也有不同的含義。你將在本文中了解亞洲國家的肢體語言。”與之對應。故選A。【4題詳解】根據“Cathyisajuniorhighschoolstudent.Shealwaysworriesaboutherstudy.Sheistryingtogetoutofthestressfromherstudies.”可知Cathy想要擺脫學習壓力，結合選項，選項B“每個人都可能承受壓力，無論你的年齡如何。本文將分享一些放松自己的方法。”與之對應。故選B。【5題詳解】根據“Sarah’smumcan’thaveagoodsleepatnight...Sarahhopestohelphermomsolvethesleepproblem.”可知想要幫助媽媽解決睡眠問題，結合選項，選項D“很多人都有睡眠問題。他們經常整晚都睡不著。這篇文章將告訴你如何快速入睡并睡個好覺。”與之對應。故選D。19、1.C2.B3.D4.A【解析】【導語】本文根據左欄的敘述，為其匹配合適的圖片。【1題詳解】根據空后的“Itisalongthinpartattheendofyourhand.”可知，它是你手末端細長的部分，應為手指。故選C。【2題詳解】根據空后的“Itisapartofacomputerthatcanshowpicturesorwords.”可知，它是電腦的一部分，可以顯示圖片或文字，應為電腦顯示器。故選B。【3題詳解】根據空后的“Itisaplacewherethingsaremadebymachines.”可知，這是一個用機器制造東西的地方，應為工廠。故選D。【4題詳解】根據空后的“Itisisaveryhighareaofland,higherthanahill.”可知，這是一片比小山還高的地方，應為山峰。故選A。20、1.A2.D3.B4.C【解析】【導語】本文主要介紹青少年的近視問題，短文通過對澳大利亞和中國學生視力的對比研究，發現每天花兩到三小時戶外活動可以減少孩子近視的機會，建議學生多去戶外活動。【1題詳解】推理判斷題。根據第一段“Spendingtwoorthreehoursplayingoutdoorseachdaycanreduceachild’schanceofbecomingshort-sighted,aresearchshows”每天在戶外玩兩三個小時可以減少孩子近視的機會，由此可推知待在室內不能減少近視的機會，故選A。【2題詳解】細節理解題。根據第三段“However,theAustralianchildrenspentanaverageoftwohoursadayoutdoors,90minutesmorethantheSingaporeanchildren”，可知澳大利亞的孩子平均每天在戶外待兩個小時，比新加坡的孩子多90分鐘。即120-90=30分鐘，所以新加坡兒童平均每天在戶外30分鐘，故選D。【3題詳解】主旨大意題。根據本段內容，結合“Butwhydoesplayingoutsidepreventusfrombecomingshort-sighted”可知主要介紹為什么在戶外可以防止近視，即為什么在外面玩對視力有好處。故選B。【4題詳解】推理判斷題。通讀全文，結合“Spendingtwoorthreehoursplayingoutdoorseachdaycanreduceachild’schanceofbecomingshort-sighted,aresearchshows”可知本文主要介紹了一項新的研究成果，所以最有可能來自科學雜志，故選C。五、完形填空（10分）21、1.A2.B3.D【解析】【導語】本文主要講述了一位患有哮喘的八年級學生為了不影響自己的學業和健康，與家長和醫生一起想出了
