【正确答案】
D
【答案解析】[解析] 动词designate的意思是：officially assign a specified status or ascribe a specified name or quality to(官方指定或正式指定给……某个特定地位、名称或品质)，这里指世界卫生组织公开承认猪流感是一种全球性的传染病。动词criticize意为“批评”；appoint意为“委派、指定”，通常指委派或指定某一职务；comment意为“评价”，它们均不符合题意。
【答案解析】[解析] 这里，in the absence of意为“缺乏”，这里是说患上猪流感的人没有接受治疗就完全康复。名词progress意为“进展、进步”；presence意为“存在、在场”，in the presence of意为“当……的面”；favor意为“支持、好感”。
【正确答案】
D
【答案解析】[解析] 本句中，come to notice意为“引起注意”，所以come to global notice是说猪流感的爆发“在全球范同内被注意到”。名词reality意为“现实、实在”，phenomenon意为“现象”，concept意为“概念”，三者均不能与come to搭配。
【正确答案】
C
【答案解析】[解析] 本句中，noted an unusually large number of hospitalizations and deaths among healthy adults是说墨西哥当局“提到在健康的成年人中有大量人住院或死亡”，这里，note作动词，意为“注意到、提到”。介词among意为“在……中”，符合题意，而其他三个介词均不符合题意。
【正确答案】
B
【答案解析】[解析] 词组crop up的意思是appear，occur，or come to one"s notice unexpectedly(突然出现、发生或被注意到)。这里词组的意思与上一句的come to notice以及note的意思相互照应，都说明了猪流感病例的发生和扩散过程。词组stay up意为“熬夜”，fill up意为“填满”，cover up意为“隐瞒、掩盖”，均不符合题意。
【答案解析】[解析] 本句是转折句，因此应该是说随着季节变冷(进入9月份)，流感病例变得多了起来。作为形容词，significant的一个主要意思是“显著的”，用英语来说就是sufficiently great or important to be worthy of attention(足够多或重要而引起注意)，比如a significant increase in sales. (销售额显著上升)。这样，significant flu activity的意思就是“流感活动显著增加”或“明显的流感活动”。另一方面，excessive(过多的，过剩的)，enormous(庞大的，巨大的)和magnificent(宏大的，壮丽的)都不与activity搭配而表示量大，比如enormous只有与amount或number搭配之后才表示“大量”。
【答案解析】[解析] 本句中，take orders from意为“接受来自……的订单”，是说联邦卫生机构接受来自各州订购新的猪流感疫苗的订单，被订购的东西用介词for引出。动词place也可以与order连用，但是place an order的意思是“发出订单”，因此既不能与from连用，也不符合题意；deliver an order通常指“根据订单发货”，而give orders通常指“发布命令”。
【答案解析】[解析] 本句中，breathing difficulties(呼吸困难，如哮喘病人)、heart disease(心脏病)等都是health problem(健康疾病)，“心脏病”在英语中也可以说heart problem，有时condition也指病情。名词issue意为“问题”，但通常指有争议的问题(an important topic or problem for debate or discussion)，而不是指病情；agony意为“痛苦、疼痛”，可以指因患某种病而遭受的痛苦，而不能指病本身；suffering也是如此。
【正确答案】
B
【答案解析】[解析] 这个词组的意思是“照料”，people caring for infants指照料儿童的人，比如儿科大夫、护士或幼儿园老师，他们与health care workers属于同一类人。词组(be) involved in指被动地卷入某件事，(be) concerned with意为“与……相关、涉及”，而ward off意为“避开、击败”。它们均不符合题意。
