A.getB.forceC.makeD.damage答案：|C解析:從四個(gè)選項(xiàng)來看,get/force要用帶to的不定式做賓語補(bǔ)足語，而damage的含義與上下文不吻合。本句應(yīng)用makesbdosth結(jié)構(gòu)。37. A.speakB.talkC.tellD.say答案:D解析：用及物動(dòng)詞say

53、,前面的內(nèi)容是它的賓語。speak常接語言做賓語；talk是不及物動(dòng)詞,不直接接賓語；tell通常接雙賓語。38. A.leadB.causeC.controlD.call答案：|D解析從下文可知，這里用call,指手機(jī)感染病毒后亂打電話，它可能會(huì)給白宮或警察打電話。39.

A.interestedB.angryC.excitedD.terrified答案：|B解析使用手機(jī)時(shí)手機(jī)感染這樣的病毒，會(huì)引起諸多不便，這讓手機(jī)用戶覺

54、得生氣。interested表示感興趣的”angry表示生氣的”excited表示激動(dòng)的”;terrified表示害怕的”。41. A.messagesB.passagesC.newsD.information答案：|A解析:news和information是不可數(shù)名詞，由后面的代詞them排除C項(xiàng)和D項(xiàng);passage的含義是通道，一段”不合題意;message是可數(shù)名詞，含義是信息”，符合文意。42. A.voiceB.passwordsC.musicD.address答案：|B解析：|本句的大意是病毒會(huì)到處散發(fā)你手機(jī)上的信息，還會(huì)記下你的密碼”。voice表示聲音”;password表示

55、密碼"music表示音樂”address表示地址”43. A.makeB.destroyC.downloadD.develop答案：|C解析:|上下文講述手機(jī)病毒，而這里講的是手機(jī)的功能，它能上網(wǎng)，發(fā)郵件，還能下載而不是毀壞或制作軟件等。44. A.jobB.taskC.workD.target答案:D解析正是由于手機(jī)有上述功能，才容易成為黑客的攻擊目標(biāo)。本題由第48空后的targets得出答案。job表示工作”;task表示任務(wù)”work表示工作”;target表示目標(biāo)，靶子”。45.A.impossibleB.possibleC.usefulD.valuable答案:B解析：|i

56、t指上文所講的事，手機(jī)受電腦病毒攻擊這件事從技術(shù)角度講是可能的。impossible表示價(jià)值的”。不可能的possible表示可能的；useful表示有用的；valuable表示有46.A.hardwareB.softwareC.computerD.equipment答案：|B解析：既然是anti-virus,當(dāng)然是殺毒軟件”即選擇softwareohardware表示硬件”software表示軟件"computer表示電腦"equipment意為設(shè)備”47.A.computerB.televisionC.InternetD.radio答案：|C解析如果電話上網(wǎng)就會(huì)和電腦一

57、樣”與本文最后一句電話不和網(wǎng)絡(luò)連接”形成對比與呼應(yīng)。48.A.strikeB.visitC.askD.attack答案：|D解析：攻擊目標(biāo)，這里和上文第44空形成呼應(yīng)，因此應(yīng)用attack（攻擊），而不用strike（打擊）,visit（參觀）和ask（問）。49.A.inB.byC.onD.with答案：|C解析在”手機(jī)上的信息、電視畫面等都用介詞on。5O.A.sendB.dialC.countD.press答案：B解析表示撥打電話”指手機(jī)受到病毒襲擊后就會(huì)不斷地?fù)艽驀壹本入娫?。dial表示撥打電話”而send表示發(fā)送”,count表示數(shù)”press表示按”均不符合文意。51.

58、ceiveB.banC.stopD.prevent答案|C解解析這種情況下急救中心的接線員就只好關(guān)閉系統(tǒng)以免受到干擾，因此用stop(停止)。receive表示接至卩”;ban表示禁止”;prevent表示阻止”。52. A.removedB.cleanedC.calledD.cleared答案：|D解析：|直到這令人討厭的病毒被清除掉，動(dòng)詞clear表示清除”而remove表示挪走”;clean表示打掃干凈”。53. A.andB.norC.orD.but答案：|C解解析本題用or表示或者說，換句話說”。54. A.stopB.avoidC.killD.find答案：|B解析手機(jī)用戶也可以避開病毒。本題與55題緊密相連，即手機(jī)不連接網(wǎng)絡(luò)，就可以避開病毒。55.
