→__________?_____,hestillforgothishomework.參考答案一、選擇題(共9題，共18分)1、C【分析】【詳解】

考查動詞的時態(tài)。句意：阿爾伯特·愛因斯坦生于1879年。小時候，很少有人猜測他會成為一位提出的理論改變世界的著名科學家。橫線部分表示過去將要發(fā)生的動作，應用過去將來時，僅有C項wasgoingtobe為過去將來時。故選C。

【點睛】

分析4個選項可以知道，該題考查的其實是不同的時態(tài)。掌握英語的時態(tài)和語態(tài)，必須掌握好英語中的助動詞(do,be,have)和時間狀語這兩個核心問題，如本題的1879,wouldchange的提示。另外也要結合使用語境綜合分析選項，最終得出答案。2、D【分析】【詳解】

考查非謂語動詞。句意：面對這么多的挑戰(zhàn)，我們不能按時完成這項任務。Sb.befacedwithsth.是固定搭配，表示“某人面對某事”，所以空處應用face的過去分詞形式faced，做狀語，故選D。3、A【分析】【詳解】

考查過去分詞。句意：從太空看，地球是藍色的。A.Seen過去分詞；B.Seeing現在分詞；C.Saw過去式；D.Beingseen被動語態(tài)。see的過去分詞表示被動，作狀語表示動作發(fā)生的背景，在意義上相當于一個狀語從句，其省略的主語(邏輯主語)theearth是主句的主語，且與主語之間存在被動關系。故選A項。4、C【分析】【詳解】

考查非謂語動詞。句意：陷入沉思中，他完全沒注意到老師走進了教室。分析句子結構可知，已有謂語動詞didn'tnotice，空處需填非謂語動詞作狀語，“陷入沉思”表達為belostinthought，故此空用過去分詞作狀語。故選C。5、C【分析】【詳解】

考查時態(tài)。句意：杰克告訴我他會回到他的祖國，但他沒有告訴我他將什么時候離開。

A.willleave將離開（一般將來時）；B.leaves離開（一般現在時）；C.wasleaving將離開（過去將來時）；D.left離開了（一般過去時）。整個句子是一般過去時。在賓語從句中，主句如果是過去時，賓語從句應該用過去時的一種。主句hedidn’ttellme是一般過去時，leave用進行時表示將來時，因此用過去進行時表示過去某一時間將要進行的的動作，故選C項。6、C【分析】【詳解】

考查形容詞詞義辨析。句意：在新冠肺炎疫情期間，建造方艙醫(yī)院來接收患者是一個有創(chuàng)意的想法。A.cheerful歡快的；B.classical經典的；C.creative有創(chuàng)意的；D.curious好奇的。根據句意及常識可知，建造方艙醫(yī)院是我們國家的一個有創(chuàng)意的想法。故選C。7、B【分析】【詳解】

考查過去分詞。句意：被指控從銀行偷錢，他正在被警察盤問。本句已有謂語wasbeingquestioned且無連詞，動詞accuse用非謂語形式，accuse與句子主語he之間構成被動關系，故用過去分詞accused，作原因狀語。故選B。8、C【分析】【詳解】

考查非謂語動詞。句意：從頂部看，體育館看起來向一個鳥巢。根據句子分析可知，此處作狀語，主語thestadium與see之間為被動關系，故應用過去分詞作狀語，故填C。9、A【分析】【詳解】

考查名詞詞義辨析。句意：我非常喜歡徒步旅行，因為我可以在途中欣賞各種風景。A.landscapes風景；B.routes路線；C.destinations目的地；D.episodes插曲。根據“hiking”“enjoy”和“ontheway”可推知，徒步旅行的過程中一路上有各種風景供人欣賞，因此“我”喜歡徒步旅行，landscapes符合句意。故選A。二、圖畫作文(共8題，共16分)10、略

考查非謂語動詞。句意：我們相信“一帶一路”倡議將造福中國經濟，對中國的未來充滿信心。分析句子可知，此處為非謂語動詞作狀語，結合漢語意思提示可知，此處convince與邏輯主語we為被動關系，所以為過去分詞形式表示被動。故填Convinced?！窘馕觥緾onvinced17、略
