43、ion A16【答案】C【譯文】所有學(xué)生都十分渴望知道他們能否通過這次考試?！究键c(diǎn)】連詞辨析用法【解析】根據(jù)句意可以排除選項(xiàng)B和D。雖然連詞if和whether都有“是否”的含義，但只有whether能與or not搭配。17【答案】D【譯文】當(dāng)這對(duì)夫妻來到這兒時(shí)，他們會(huì)去公園?！究键c(diǎn)】動(dòng)詞時(shí)態(tài)【解析】在這句中they _to the park是主句，When the couple _ here是從句。當(dāng)主句是將來時(shí)態(tài)或表示將來意義時(shí)，從句用一般現(xiàn)在時(shí)代替將來時(shí)。18【答案】B【譯文】“我在哪兒都找不到湯姆?！薄八欢]走多遠(yuǎn)，我剛才還聽見他打電話了呢”?！究键c(diǎn)】考查情態(tài)動(dòng)詞與虛擬語(yǔ)氣用法【解

44、析】語(yǔ)境表示語(yǔ)氣很肯定的否定判斷推測(cè)：我剛才還聽見他打電話了，因此他一定沒走多遠(yuǎn)。用cant have done。shouldnt have done表示本不應(yīng)該做某事；mustnt have done表示禁止做某事；而neednt have done指的是本來沒必要做某事。19【答案】D【譯文】無(wú)論老少，人們的想法都能與時(shí)俱進(jìn)?！究键c(diǎn)】動(dòng)詞短語(yǔ)【解析】選項(xiàng)A與keepwith搭配時(shí)應(yīng)為keep in contact with。選項(xiàng)B無(wú)法與keepwith搭配。選項(xiàng)C，keep touch with意為與保持聯(lián)系。只有keep pace with符合題意，意為與并駕齊驅(qū)。20【答案】C【譯文】

45、說實(shí)話，幫助他們戒除網(wǎng)癮很困難，但是我們正在努力解決這個(gè)問題?！究键c(diǎn)】動(dòng)詞時(shí)態(tài)【解析】根據(jù)語(yǔ)境意義，我們可知這個(gè)動(dòng)作正在進(jìn)行中，因此用現(xiàn)在進(jìn)行時(shí)。21【答案】B【譯文】最近發(fā)生了一次地震，造成死亡l00人，300多人受傷?！究键c(diǎn)】非謂語(yǔ)動(dòng)詞【解析】第一空用kill的現(xiàn)在分詞作狀語(yǔ)，表示主動(dòng)含義和補(bǔ)充說明；第二空用過去分詞后置“300（people）”，意為“受傷的”。22【答案】C【譯文】這個(gè)國(guó)家西南部50英里的地方坐落著一座美麗的高山。【考點(diǎn)】倒裝結(jié)構(gòu)及主謂一致【解析】首先要知道此句為倒裝結(jié)構(gòu)，另外根據(jù)句意可知，主語(yǔ)為“the famous beautiful mountain”，指的是一座

46、漂亮的山，所以謂語(yǔ)也應(yīng)該用單數(shù)。23【答案】A【譯文】每個(gè)人的生命里都有一段什么事情都看似十分艱難的時(shí)期?！究键c(diǎn)】定語(yǔ)從句【解析】本題的關(guān)系詞引導(dǎo)定語(yǔ)從句修飾periods，指的是一段時(shí)期，并在從句中作時(shí)間狀語(yǔ)，因此選A。24【答案】B【譯文】只要你的作業(yè)是自己做的，劉老師并不介意你晚些再交上來?！究键c(diǎn)】動(dòng)名詞用法【解析】mind和delay后都要接動(dòng)名詞形式。因此選B。25【答案】D【譯文】她從來也沒準(zhǔn)備要輟學(xué)?！究键c(diǎn)】倒裝結(jié)構(gòu)【解析】當(dāng)否定詞或含有否定意義的詞、短語(yǔ)放在句首時(shí)，句子一般要部分倒裝，因此只能選擇B或D。但因?yàn)閎e ready to do為固定搭配，意為“準(zhǔn)備做某事”，故選D；

47、B項(xiàng)缺少謂語(yǔ)。Section B26【答案】is【譯文】紐約時(shí)報(bào)很受那些政治家們的歡迎?！究键c(diǎn)】主謂一致【解析】在國(guó)家、報(bào)刊、學(xué)科和書名中雖有類似單詞的復(fù)數(shù)形式出現(xiàn)，但它們只是構(gòu)成這個(gè)詞組的一部分，并不是真正的復(fù)數(shù)。此類詞還有the united states，maths等。27【答案】more friendly【譯文】你們鎮(zhèn)上的人比我們預(yù)料的更加熱情?！究键c(diǎn)】形容詞的比較級(jí)【解析】根據(jù)句子結(jié)構(gòu)及句中的than一詞，可以知道是兩種程度的比較。同時(shí)，friendly是多音節(jié)詞，故在原型前加more，句中的“far”可以修飾比較級(jí)。28【答案】shorten【譯文】傷病問題可能會(huì)縮短籃球運(yùn)動(dòng)員的職

48、業(yè)生涯?！究键c(diǎn)】詞性轉(zhuǎn)換【解析】情態(tài)動(dòng)詞后應(yīng)加動(dòng)詞原形，所以空格處應(yīng)填寫short的動(dòng)詞形式的原形。而形容詞short的動(dòng)詞形式是在其后加上en，同類詞還包括widewiden，fastfasten等。29【答案】told【譯文】我會(huì)代替你告訴瑪麗真相，但我寧愿是你告訴她的。【考點(diǎn)】虛擬語(yǔ)氣【解析】 would rather后接sb再加上動(dòng)詞時(shí)，要用一般過去時(shí)表示虛擬，可簡(jiǎn)記為would rather sb.did。30【答案】will have been【譯文】到大學(xué)畢業(yè)后，我將已經(jīng)做了15年的學(xué)生了。【考點(diǎn)】動(dòng)詞時(shí)態(tài)【解析】by the time接將來時(shí)間或一般現(xiàn)在時(shí)的句子，表示將來預(yù)計(jì)完

49、成的動(dòng)作，主句要用將來完成時(shí)。31【答案】be translated【譯文】這首美麗的詩(shī)應(yīng)該被翻譯成中文，因?yàn)樗苤档靡蛔x?！究键c(diǎn)】被動(dòng)語(yǔ)態(tài)【解析】情態(tài)動(dòng)詞should后加動(dòng)詞原形；同時(shí)，poem和translate之間為被動(dòng)關(guān)系，所以應(yīng)為be translated。32【答案】economics【譯文】根據(jù)最新報(bào)道，越來越多的年輕人傾向于學(xué)習(xí)經(jīng)濟(jì)學(xué)和社會(huì)科學(xué)?！究键c(diǎn)】詞性轉(zhuǎn)換【解析】由句意可知是學(xué)習(xí)某一門學(xué)科，economy為“經(jīng)濟(jì)”之意，經(jīng)濟(jì)學(xué)應(yīng)為“economics”。33【答案】had gone【譯文】如果這個(gè)舞者是搭乘飛機(jī)去美國(guó)的話，她可能在墜機(jī)事故中遇害了?！究键c(diǎn)】虛擬語(yǔ)氣【解析】

50、根據(jù)句意，可判斷出此句是對(duì)過去的虛擬，此時(shí)，主句要用wouldmightcould have done的形式，而從句要用had done，即過去完成時(shí)。故應(yīng)填had gone。34【答案】Caught【譯文】因?yàn)橥蹈`而被店主抓獲時(shí)，這個(gè)男孩顯得很羞愧?！究键c(diǎn)】分詞作狀語(yǔ)【解析】根據(jù)句子結(jié)構(gòu)分析，可知catch和the boy之間是被動(dòng)關(guān)系，且前一部分作句子的時(shí)間狀語(yǔ)。當(dāng)分詞作狀語(yǔ)，邏輯主語(yǔ)和動(dòng)作之間為主動(dòng)時(shí)，用現(xiàn)在分詞；而表示被動(dòng)時(shí)，則用過去分詞。35【答案】making【譯文】很明顯你是有意要傷害我的自尊的，因此道歉是沒有用的?！究键c(diǎn)】動(dòng)名詞用法【解析】its no use后要加動(dòng)名詞形式。

51、指的是“做是沒有用的”。要在其后加動(dòng)名詞的短語(yǔ)還包括there is no point，be worth，look forward to等等。Part Reading ComprehensionTask136【答案】C【題型】細(xì)節(jié)題【解析】題干意為“根據(jù)文章，英語(yǔ)是”。由第一句話我們可知，英語(yǔ)并不像中文那么悠久古老，故應(yīng)選C。not soas意為“不像那么”。37【答案】C【題型】推理題【解析】題干意為“漢堡最初是”。由文章的第三段，我們可知，一些來自漢堡的德國(guó)人誤認(rèn)為美國(guó)人問他們來自哪里，所以回答到我們來自漢堡。然后美國(guó)人發(fā)明了一種面包，稱之為漢堡包的。因此，漢堡最初只是德國(guó)的一個(gè)城市。38

52、【答案】D【題型】細(xì)節(jié)題【解析】題干意為“根據(jù)文章，下列哪一個(gè)陳述是正確的”。漢堡最初是德國(guó)的一個(gè)城市，故A項(xiàng)是錯(cuò)誤的。文中并沒有提到美國(guó)人喜不喜歡漢堡包，因此B選項(xiàng)也是錯(cuò)誤的。文中第二段提到漢堡包并不是由火腿做的，因此C也是不正確的。第三段提到一百多年前，由后文我們也可知美國(guó)人在那個(gè)時(shí)候發(fā)明了漢堡包。故選項(xiàng) D是正確的。39【答案】A【題型】細(xì)節(jié)題【解析】題干意為“最開始賣漢堡包的?！庇傻谌挝覀兛芍?，A選項(xiàng)“美國(guó)人”是正確的。40【答案】D【題型】推理題【解析】題干意為“在讀了這個(gè)故事之后，我們可知漢堡包這個(gè)詞來源于”。閱讀文章，我們知道是美國(guó)人看到了來自德國(guó)漢堡的人吃一種圓片狀牛肉而發(fā)明

53、漢堡包，因此漢堡包這個(gè)詞來源于美國(guó)。41【答案】B【題型】主旨題【解析】題干意為“文章旨在告訴我們”。通過閱讀全文我們可知，文章告訴我們做一個(gè)優(yōu)秀的少年應(yīng)具備的四大品質(zhì)。故選B。選項(xiàng)A，C，D都是這幾個(gè)條件中的一個(gè)，過于片面了，不能代替全文的思想。42【答案】D【題型】細(xì)節(jié)題【解析】題干意為“作為優(yōu)秀的青年首先要擁有”。文章說了the basic，是the first的轉(zhuǎn)換說法，故應(yīng)選擇D，健康的身體。43【答案】A【題型】細(xì)節(jié)題【解析】題干意為“一個(gè)優(yōu)秀的年輕人應(yīng)該幫助他人”。根據(jù)文中的我們應(yīng)該樂于且毫無(wú)怨言地幫助那些陷入困境的人，可以看出答案是A。44【答案】C【題型】細(xì)節(jié)題【解析】題干意

55、ific activities that help to improve your English”可以找到答案。47【答案】materials【解析】由文中第一段第三句話“one can also have access to some interesting language learning materials in the Leaming Tour”可以找到答案。48【答案】use computers【解析】由文中第一段第四句話“participators will be taught the way to use computers and audi0-visual faciliti

56、es in the center”可以找到答案。49【答案】1：00-2：00 pm【解析】由文中第二段中“while the latter one is l：002：00 pm”可以找到答案。the latter one意為“后者”，指的是文中的星期四。50【答案】ID card N0【解析】由文中第三段最后一句話“people can go to Tin Ping building on the 4th floor or email your name，ID card N0and date of joining the tour to Miss Feng at fengcahkeduhk”可以找到答案。Task 4這是一組汽車專業(yè)英語(yǔ)：AEngine Fuel System發(fā)動(dòng)機(jī)燃油系統(tǒng) BLights and Wires車燈和線路CStarting System啟動(dòng)系統(tǒng) Dunder pressure受壓E10wer hood lines低發(fā)動(dòng)機(jī)罩 Fheatedtreated熱處理Gcontac
