22、a卷一、單項填空1解析：句意：當你點蠟燭時，它們會發(fā)出某種氣味。give off放出，排放(氣味等)。答案：b2解析：句意：他將移交他的位子給兒子。hand over移交。答案：b3解析：句意：如果司機無證駕駛，他將會受到罰款。permit“許可證，許可”。permission“許可，允許”；allowance“津貼，補助費”；admittance“進入權(quán)”。答案：b4解析：答語句意：無論你選什么，我都沒有意見。此處為主語從句，故排除c項。which表示“哪一個”，要有選擇的范圍，故排除。答案：a5解析：句意：洗澡后確保將煤氣關(guān)上，不然會引起危險。otherwise“否則，不然的話”符合題意。

23、答案：c7解析：get about四處走動，(消息等)傳開；get away(from)逃離；get across使被理解；get off下車。句意：作為老師，我們理應(yīng)讓學(xué)生理解正確的學(xué)習(xí)方法是多么的有益。答案：c8解析：rescue救援；donate捐贈；inspire鼓勵；assess評估，評定。句意：火災(zāi)之后，他們就安排我們的檢查員之一史密斯先生來評估損失。答案：d9解析：句意：書太多了！拿走哪些，留下哪些對我們來說不容易決定。and前后為并列結(jié)構(gòu)。答案：b10解析：句意：經(jīng)過一下午的激烈的討論，他們最終向我們宣布了他們的決定。tell告訴，后直接接人作賓語；declare宣布，宣告，應(yīng)

24、用declare to sb.sth.；state陳述；make做。答案：b11解析：考查詞義辨析。在用法上只有assist與介詞in搭配，assist sb.in (doing) sth.幫助某人做某事。答案：c12解析：句意：他是一個具有先進思想的人，他經(jīng)常提前做好詳細的計劃。advanced形容詞，作定語修飾名詞ideas；in advance“提前”，固定短語。in advance of是介詞短語，其后要有賓語。答案：c13解析：donation“捐贈(物)”；relation“關(guān)系”；intonation“語調(diào)”；domination“支配，控制”。句意：據(jù)報道政府將把所有私人捐贈交

25、給遭受洪災(zāi)的地區(qū)。答案：c14解析：句意：我過去和朋友們靠書信交流，而現(xiàn)在用互聯(lián)網(wǎng)更方便了。correspond with“與通信”；meet with“碰見”；come up with“提出”；put up with“容忍”。答案：d15解析：句意：這兩則最新的新聞中，后者比前者更有趣。the latest最新的；the latter兩者中的后者。答案：a二、完形填空解題導(dǎo)語：在母親的“脅迫”下，作者逐漸迷戀上了邁克爾杰克遜的歌聲和動作。當他逝世這一噩耗傳開后，作者感到無比失落。雖然人們對他的非議早已煙消云散，可是作者依然播放著他的歌曲，在音樂聲中緬懷心中的偶像。1解析：此處是對過去的回憶，

26、敘述的是作者“孩童”時代的事情。另外，第三段中的“my childhood”也是提示。答案：b2解析：本句提到作者的母親經(jīng)常購買邁克爾杰克遜的音樂專輯，由此可知用sale。on sale 表示“出售，折價銷售”。答案：d3解析：下文提到作者對邁克爾杰克遜在thriller中像狼一樣的外貌感到無比恐懼，由此可知作者當時不敢觀看，所以是作者的母親“強迫”作者和她一起欣賞。答案：b4解析：前半句敘述的是對他的外貌的恐懼，后半句描寫的是對他的聲音以及動作的入迷，所以選a項，表示的是讓步關(guān)系。答案：a5解析：雖然他的外貌恐怖，但是他的聲音優(yōu)美，動作嫻熟，深深地“迷住”了作者。fascinated 表示“

27、入迷的，感興趣的”。答案：c6解析：上文提到作者迷戀他的聲音和動作，所以自己開始慢慢收集他的專輯。build表示“創(chuàng)建，建立”。答案：c7解析：作者堅持不懈地收集，直到“擁有”了邁克爾杰克遜全部的唱片和錄像帶。b項表示“獲得”時通常指獲得物質(zhì)利益，因此語義不太恰當。答案：a8解析：此處 struck 原形是 strike，表示“突然爆發(fā)”。a 項的動詞原形是 stick，表示“刺入，粘貼”，不符合語境。答案：b9解析：聽到邁克爾杰克遜在6月份突然去世的消息，作者感覺自己童年時代的一個重要的組成部分也隨之“消亡”。答案：a10解析：上文中提到作者癡迷于他的優(yōu)美的聲音和嫻熟的動作，由此可知作者一直非常喜歡他的音樂和舞步。答案：d11解析：根據(jù)上文敘述的作者小時候的經(jīng)歷可知，作者是在母親的“介紹”下開始喜歡上他的。答案：a12解析：結(jié)合上下文可知他“曾經(jīng)”是一個才華橫溢精力充沛的表演者，后來成為一個總是戴著防護物以遮蔽陽光的可憐人物。答案：c13解析：who always needed a shield from the sun是定語從句，修飾先行詞person。答案：a14解
