A case released online in a letter by Annals of Oncology（《肿瘤学年报》）indicates how big a_________(52)of losing fingerprints is.

After three years on the_________(54),the patient decided to visit U.S.relatives last December. But he was stopped by U.S. customs officials__________(55)4 hours after entering the country when those officials couldn't get fingerprints from the man. There were no distinctive swirly（旋涡状的）_________(56)appearing from his index finger.
U.S.customs has been fingerprinting incoming foreign visitors for years,Tan says.Their index fingers are _________(57)and screened against digital files of the fingerprints of bad guys一terrorists and potential criminals that our federal guardians have been tasked with keeping out of the coun-try. Unfortunately,for the Singaporean traveler,one potential_________(58)effect of his drug treatment is a smoothing of the tissue on the finger pads.__________(59),no fingerprints.
"It is uncertain when fingerprint loss will__________(60)to take place in patients who are taking capecitabine,"Tan points out. So he cautions any physicians who________(61)the drug to provide their patients with a doctor's note pointing out that their medicine may cause fingerprints to disappear.

选项 _________(55)
A:in       
B:at       
C:for       
D:on
答案C
解析根据上下文的意思，失去（losing）的应该是fingerprints。 fingerprints是复数形式，指代它的代词是them。其他三个代词都不合适。
空格所在句大意是，要用一个实例说明失去指纹是一个大问题。所以只有选项D最合适。
第二段描述了实例的细节。第一句说病人用一种药名为卡培他滨的抗癌药治疗他的鼻咽癌。所以treat是必然的选择。cut“切割” ,find“寻找”和smooth“弄平”都与上下文接不上。
从上下文判断，"After three years on the...（经过三年的······）”的后面应该接“用药”、“治疗”等字眼，所以选drug是正确的。选项recovery“康复”,diet'‘节食”或diagrosis“诊断”都与后面提到的病人进入美国受阻的事件不相符。
for表示时间上“达到”,for 4 hours意为“长达四个小时”。
美国海关因为采集不到那位癌症患者的指纹样本，于是盘问了他四个小时。所以本句提到的swirly应该与marks搭配，意思是“旋涡状指纹标记”。
为了防止恐怖分子和罪犯进入美国，美国海关通过电脑对入境者进行指纹采样，然后与指纹库进行比照。根据常理，海关要检查每一位入境者的指纹。采样的手指是食指。后面的screened是解题的重要线索，引导读者选A，即printed。这里printed = finger-printed“采集指纹样本”。其他三个选项located“找出”,cured“治疗”和placed“放置”都与上下文的意思接不上。
实例中的新加坡人用了抗癌药后的一个副作用是指纹消失，这是一种不良反应。所以，good, main, normal都不符合上下文的意思，只有side才是答案。side effect意为“副作用”。
前面句子提及的服杭癌药是因，本段最后一句是果，连接词应该用 Hence。 However表示转折关系，Moreover和Furthermore表示“进一步”的关系，与上文连接不上。
本段表达的意思是：由于癌症病人服用卡培他滨后指纹何时开始消失还－不清楚，所以主治医生要提前为病人开具指纹可能会消失的证明单。like, decide或have都与上下文的意思不符，只有begin最合适。
参阅上一题的题解。本题四个选项词的前三个字母都是pre，只要知道prescribe的词义是“开处方”就会选D。
第五段的意思是：“那位新加坡游客最后终于进入了美国。我猜想他护照上的名字没有带有任何危险信号。但是他同样要带有医师开的证明单——并且要随身携带。”本题without是答案。
哪一个政府机构许可(approved)使用该类抗癌药？就是本段第一句提到的the Food and Drug Administration。四个选项中，只有关系代词which能指代the Food and Drug Administration，它是approved这一动作的发出者。
最后一段表达的意思是：过去该药列出的不良反应只包括呕吐等，没有列出指纹消失这一副作用，现在应该补上这一条。所以，updating“更新”是答案。
最后一段最后一句中，为了强调no where而将其前移，这时，句子要用部分倒装的形式。所以，答案是B。
