  答案与解析

  23.D。从第二段的首尾句来看,第一句讲的是三个主要发生埃博拉疫情的国家,尾句说的是其他发生埃博拉病例的国家,故D(哪些地区目前受到疫情影响)是正确答案。

  【备考助手】段落大意一般是段落的首旬和尾句,很少的时候是在中间的句子,特别是中间的句子带有“yet,but,however”等转折关系的时候。如果段落之中没有明显的主题句,则需要根据大意或者高频词汇进行判断。

  24.A。第三段首句是主题句,“如果你没有去过三个疫情感染的国家,那么你感染埃博拉病毒的风险为零”,即讨论的是埃博拉病毒的感染,故A(我有没有感染埃博拉病毒的风险?)是正确答案。

  25.C。第四段的主题句是首句,埃博拉病毒的症状不是很具体,病人一般在病毒感染一周之后才会出现典型的症状,所以该段主要谈论埃博拉病毒的症状。因而D(我如何知道自己是否感染了埃博拉病毒?)是正确答案。

  26.E。第五段的主题句是首句,埃博拉病毒具有破坏性是因为它会在人体的任何器官内进行攻击和复制,故E(埃博拉病毒对身体到底有何影响?)是正确答案。

  27.E。题干:最早埃博拉病毒爆发是在__________发现的。利用出题顺序与段落顺序一致的原则,利用题干关键词the initial Ebola outbreak可以定位到第二段的首句,“即到目前为止,只有西非的三个国家正在经历埃博拉病毒的大爆发”,所以答案为E(西非的三个国家)

  28.C。题干:SARS和埃博拉病毒的不同之处在于__________。利用题干关键词difference,SARS和Ebola可以定位到第三段第二句,可知与其他在空气中传播的病毒如SARS不同,埃博拉病毒只能通过直接与感染人群接触而传播,故选C(传播方式)。

  29.F。题干:病人感染埃博拉病毒的症状最初出现 __________ 。利用题干关键词symptoms和firstappear可以定位到第四段的前两句,可知埃博拉病毒的症状不具体,通常在感染一周之后才有明显症状,症状最早出现时感染两天后,最晚是感染三周之后,所答案为E(在好多天的范围之内)。

  30.A。题干:埃博拉病毒通过与__________的接触进行传播。利用题干关键词Ebola virus,transmits和contact可以定位到第三段的第二句和第三句,可知与其他在空气中传播的病毒如SARS不同,埃博拉病毒只能通过直接与感染人群接触而传播,具体来说,埃博拉通过与体液的接触进行传播。因此该题答案选A(受感染的体液)。
