 文章精要
  本文主要介绍了科学界对SARS的研究,包括其症状、诊断、治疗、传播途径等情况。关于SARS还有很多问题有待于解答。SARS的症状类似于感冒,人会发烧,感到身体疼痛。SARS病毒主要是通过空气传播的。
  62.A词义辨析题。该句意为SARS是在2003年2月在河内首次被—的。detect意为发现,察觉,例:The dentist could detect no decay in her teeth.(医生检查了她的牙,未发现龋齿。),故选A。其他三项:catch意为抓住,赶上;disclose意为揭露;reveal意为揭示。
  63.B逻辑衔接题。该句意为SARS是在2003年2月在河内首次被发现的,——从那时起,SARS已经感染了l5个国家的l600人,其中63人死亡,此处前后两句为承接关系,故选B。
  64.B惯用搭配题。该句意为在这一点上,人们对于该病的许多疑问都没有找到答案。at this point指在这一点上,符合该处的语义关系,故选B。at this time意为在这个时候;没有at this aspect/instance的说法,应为in this aspect(在这个方面)和in this instance(在这个情况下)。
  65.D惯用搭配题。该句意为SARS的症状是首先表现为高于100.4华氏度的高烧、发冷、头疼或者身体。startwith是固定搭配,意为以……开始,带有伴随的意味,故选D。start from意为从……开始,开始于……,强调具体的事物;startover意为重新开始。
  66.C词义辨析题。hurt意为伤害,受伤;sore意为痛处,一般为嗓子疼;ache意为疼痛,一般指身体某
  处的疼痛;feeling意为感情,情感。根据上下文此处要表达身体的疼痛,故选C。、

  68.C词义辨析题。ventilation意为通风,该句大意为在10%到20%的病例中,患者需要一一通风进行呼吸。根据常识,医院通常为呼吸困难的病人提供呼吸机,呼吸机是机械设备。四个选项中automatic意为自动的;artificial意为人工的;mechanical意为机械的;controlled意为可控制的,故选c。
  69.D逻辑衔接题。该句意为症状在2到7天内开始出现,由上下文可知此处说的是一般的情况。regularly意为有规律地;ordinarily意为普通,平常;traditionally意为传统上;generally意为一般,通常,故选D。
  70.B语法结构题。前文提到,症状一般在2到7天内开始出现,此处为转折:但是有报告显示症状出现需要10天,可见人们对SARS还不是很了解,只是一种推测。might为情态动词,表示较小的推断和可能,故选B。
  71.C词义辨析题。cultivate意为培养;foster意为培育;develop意为发展;design意为设计。此处表
  达科学家开发出一个实验室测试来诊断SARS,故选C。
  72.B语法结构题。that此处引导evidence的同位语从句,故选B。
