　　解析：
　　51.D [解析]豬流感是swine flu。文中出現(xiàn)過多次。
　　52.B[解析]從上下文得知，患病的學(xué)生中沒有人住院，有一些已經(jīng)康復(fù)，因此他們的癥狀應(yīng)該是比較輕的。所以選B。
　　53.B[解析]學(xué)校里的學(xué)生有了流感樣的癥狀，肯定是沒能上學(xué)。
　　54.D[解析]從上下文可以看出，紐約衛(wèi)生官員檢驗了8名學(xué)生的血樣后斷定他們很可能是患上了豬流感。suffer from意為患……病。
　　55.C [解析]疾病防控中心對紐約衛(wèi)生官員的診斷予以證實。diagnosis是"診斷"的意思。
　　56.A [解析]顯然此處應(yīng)為確診的豬流感患者數(shù)量the number of confirmed swine fluCases。
　　57.B [解析]從上文和接下來的"no sign"就可以推斷出此處應(yīng)為同樣的表達方式。sign意為跡象。
　　58.B [解析]其他學(xué)校沒有爆發(fā)豬流感的跡象。
　　59.C [解析]學(xué)校的一些學(xué)生是在墨西哥度的春假。spring break指春假。"度假"用動詞spend。
　　60.B [解析]從上下文可知，*尚未確定被確診為豬流感的學(xué)生中是否有誰去過墨西哥。
　　61.A[解析]從上下文可知，某位去墨西哥旅游的學(xué)生自己可能沒有表現(xiàn)出任何流感癥狀，但卻把流感傳給了其他人。
　　62.B [解析]生病在家的學(xué)生在癥狀消退后，繼續(xù)在家觀察48小時。stay home呆在家里。
　　63.A[解析]接下來一句說，如果癥狀嚴重，人們應(yīng)該去醫(yī)院。這是一個轉(zhuǎn)折句，因此前面的句子應(yīng)該相反，即沒有必要上醫(yī)院。There is no：need to do sth.沒必要做某事。
　　64.B [解析]as with的意思是"和……一樣;正如"。
　　65.D [解析]從后面的"responded"一詞可以推斷出前面應(yīng)該是"被問到"，即"Asked"。
　　參考譯文
　　紐約甲型H1Nl流感
　　紐約市長邁克爾·布隆伯格周日稱，疾病預(yù)防控制中心已經(jīng)證實來自紐約一所預(yù)備學(xué)校的八名學(xué)生感染甲型N1H1流感。他說這幾名學(xué)生只是有輕微癥狀，沒有一名被送往醫(yī)院。部分學(xué)生已經(jīng)痊愈。
　　布隆伯格說，上周100多名學(xué)生因類似該流感的癥狀而不能上學(xué)。紐約市衛(wèi)生官員周六對8名學(xué)生的血樣進行了檢驗，得出結(jié)論：這幾名學(xué)生很可能患有豬流感，疾病預(yù)防控制中心周日證實了這一診斷。
　　公告將美國確診的豬流感病例的數(shù)字上升到20例。布隆伯格說，現(xiàn)在并沒有爆發(fā)全市流感的跡象，也沒有跡象表明潛在甲型H1N1流感會在其他學(xué)校爆發(fā)。
　　布隆伯格說，這所學(xué)校的一些學(xué)生在墨西哥度過了春假，但是美國*并不確定這些被確診患有豬流感的學(xué)生中是否有人在墨西哥度過春假。去過墨西哥的人可能并沒有任何的流感癥狀，但卻把流感傳給了別人。
　　布隆伯格號召生病在家的學(xué)生在癥狀消退后，繼續(xù)在家觀察48小時。
　　布隆伯格說，如果癥狀屬于普通流感，就沒有必要去醫(yī)院。如果癥狀加重，就如患有任何疾病一樣，病人必須去醫(yī)院就診。
