___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________參考答案單項選擇：21．A[考查冠詞。name此處表泛指，使用不定冠詞；placeanorder(forsth.)為固定短語，意為“訂購(某物)”。]22．D[考查短語辨析。根據語境，不買這款車的原因是此車不實惠而且即將過時。onthewayout即將過時，符合句意。outofshape變形；freeofcharge免費；outoforder出故障。]23．C[考查時態。根據語境，這個時間不適合，是因為那時我將在參加一個重要會議，表示將來某個時間點正在做某事，應使用將來進行時。]24．B[考查連詞。句意為：在發展中國家，出生率總是很高，然而在發達國家出生率則相對較低。while在此為連詞，意思是“然而”，表示對比。]25．A[考查名詞詞義辨析。根據句意，應是在10英里范圍內，limit范圍，符合句意。distance指兩地間的距離。]26．B[考查形容詞詞義辨析。由but表轉折可知與公司目前的困難相對的是我們對其未來發展還是很樂觀的。optimistic樂觀的，符合句意。concerned關心的；enthusiastic熱情的；satisfied滿意的。]27．C[考查非謂語動詞。句意為：經理說“一旦決定了，我想要計劃盡快被執行?！眕rogram和carryout之間是被動關系，所以應該使用seesth.done句型，表示“看到某事被……”。]28．D[考查時態。beabouttodo意為“正要做，馬上要做”，強調即刻要發生的動作，常跟when引導的時間狀語從句連用，表示“正要做……，這時……”。begoingtodo表示做事先計劃或安排好的事情或者自然現象的發生；betodo表示按照計劃或安排要發生的事。]29．B[考查動詞詞義辨析。句意為：這些措施是否會對美國經濟有積極的影響，現在還很難預測。predict預測(多指主觀的)，符合句意。measure測量；count計算；promise允諾。故選B項。]30．C[考查副詞詞義辨析。句意為：乘客在機場被延誤兩個小時后，終于登上了飛往巴黎的飛機。definitely無疑地，確定地；eventually最后，終于；absolutely完全地，絕對地；formally正式地，形式上地。根據句意可知選C項。]31．C[考查動詞短語辨析。句意為：他是個不受歡迎的人，但我又不知如何趕走他而又不傷害他的感情。getridof除掉，去除；擺脫，打發走，符合句意。putupwith忍受；comeupwith趕上，想出(主意，建議等)；getalongwith與某人相處。]32．D[考查部分否定。根據前一句“agreewithmostof...”的陳述，可推斷后句應是不贊成所有的內容。noteverything為部分否定。]33．B[考查with復合結構。attach...to...把……貼/系/安裝……上。在with結構中tag與attach之間為被動關系，因此用過去分詞作賓補。]34．B[考查讓步狀語從句。句意為：這種新手機的使用者可以查看他們的電子郵件，無論他們在什么地方。此處wherevertheyhappentobe相當于nomatterwheretheyhappentobe。]35．A[考查狀語從句。句意為：無論這本故事書多有趣，我不得不集中精力在我的功課上而將它收起來。however和nomatterhow都可用來引導讓步狀語從句，從句應是陳述語序，how和however后應緊跟形容詞。]完型填空：36．A[結合第二段Obama的反應doubt以及“ifsomethingwaswrongwithme”可推知A項最能表達他當時的感情。]37．C[該空與第一空對應，Obama之所以感到震驚，是因為看到某黑人為了變白，不惜用美白的化學產品損毀皮膚。apply涂抹，用法為applythechemicaltohisskin。]38．B[由下文“wonderedifsomethingwaswrongwithme”可知Obama是開始疑問自己是誰。]39．D[站在鏡子前，看著自己的膚色揣測，其他選項不合句意。]40．B[strugglewithhisidentity與他的身份作斗爭，與下文doesn’tseeitasaproblem對照。]41．C[由but可知此處要選與problem意思相反的詞，advantage優勢，有利條件，符合句意。]42．C[當選為美國第一位黑人總統，Obama創造了歷史。]43．A[與第五段第一句中的“________backtoHawaii”相對應。]44．D[根據語境可知10歲時，Obama返回了夏威夷。movebacktosp.返回某地。]45．D[根據語境可知同學的尖銳和諷刺性的問題應該會讓小Obama感到難堪，所以他對同學們撒謊以掩飾這種尷尬和難堪，故選D項。]46．B[情況發生轉變是在Obama結交了一些與他背景相似的伙伴之后。]47．D[Obama一直對自己的黑人身份感到困惑，所以能夠影響他的也必定是與他背景相似的人。由下文的提示詞“theirexperiencesbackinAfrica”以及“hisAfricanorigin”也能推出答案。]48．B[turnbackto翻回到，回溯到；faceupto勇敢地面對；takeupwith致力于；giveupto讓給，交給。由上文helped以及下文Obama的積極的改變可知B項正確。]49．B[由下文中的But可知，Obama用強有力的演講說服人們接受他的黑人身份，說明一開始很多人并不看好他，B項符合語境。]50．C[由前一句話可知在Obama競選總統初期，很少有人看好他，許多人懷疑他的獨特的背景。]51．C[此處指Obama將他成長的痛苦轉變為一種有力的工具。damage指損害；pain指長時間不間斷的疼痛，也可指心靈的傷痛；ache指局部的持續的疼痛；injury常指身體上的外傷。由上下文語境可知選C項。]52．A[下文Obama的言辭是為了讓人們相信并接受他的觀點，故選A項。]53．B[多個世紀以來，美國黑人、白人地位都不平等，Obama當選總統克服了人們對黑人的偏見，故選B項。]54．C[馬丁·路德·金的夢想是：評判一個人的標準不是他的膚色，而是他的品格優劣。]55．C[兩個by后的內容是相對的，用not...but...固定結構表示“不是……而是…
