10、学家都在争相研究如何快速确诊、治疗一种新型致命疾病并阻止它的传播。非典（SARS）严重急性呼吸道综合症最初于2003年2月在河内查出，随后有15个国家的1600多人受到感染，其中63人死亡。目前就这一疾病，疑问多于答案。感染非典的初始症状包括：超过华氏100.4度的高烧，打寒颤，头痛和身体疼痛。患者在一周之内会出现干咳症状，并且可能导致呼吸短促。10%20%的患者需要有强制通风设备才能呼吸。约有3.5%的病人会死于这种疾病。通常经过27天的潜伏期后开始出现症状，但也有报告表明，其潜伏期可长达10天。科学家已经快要研制出诊断非典的实验室测试方法。就当前而言，该疾病的诊断主要通过相关症状来判断。还
11、未有证据显示抗生素和抗病毒药物能治愈非典，因此医生主要采用支持性治疗方法。非典病人要被隔离以降低传染他人的风险。尽管科学家并不确定，但有些研究者认为非典病毒是一种新发现的冠状病毒，与导致普通感冒的病毒属于同一家族。大多数病例似乎都是通过非典病人咳嗽和打喷嚏时排除的唾液传染的。患者的家庭成员和照料病人的医护人员感染此疾病的几率最大。但最近香港发生的病例表明，非典也可通过空气传播，非典病毒还可能在门把手或其他物体表面存活23个小时。然而卫生专家也称，与非典患者短期共用电梯这种情况尚不至于感染上非典。31.A 解析：“检测出病情”应是detect the disease，此处指“非典第一次被检测出”
12、，应该是was detected，故选A。（词汇搭配题。B项caught可指感染疾病，多用主动态；C项disclose“揭露”和D项reveal“透露”一般不与疾病搭配。）32.B 解析：本句意思是“非典自2003年被检测出来后共有1600多人感染”。前后两个分局语义并列且稍有递进，故选B。（句意关系题。A项but和D项yet都表转折，而C项or表选择，据不符合句意。）33.B 解析：上一句说，“自那以来已经有1600多人感染该疾病，其中63人死亡”；本句话则说，“对这种疾病，疑问多过答案”，两句话之间最佳的语义关联词应该是表示时间的“目前，在现阶段”。at this point符合句意。（短
13、语含义题。aspect表示“方面”，如consider sth. in all its aspects。instance不与at搭配，in this instance表示“在这个情况下”，所以不选D。at this time表示“在此时”，句中也讲得通。只是文中突出“现阶段”的含义，用point更好。）34.D 解析：本句描述非典的初始症状。start with表示“以.开始”，后街表“某种状态”的短语，符合此处语境，故D正确。（短语搭配题。start from表示“从.开始”，后接“起始点”，暗含“到某个终点（to）”之意，此处不合适。选项B和C一般不与start搭配使用。）35.C 解析：根据句意，非典的症状包括“全身疼痛”，因此，应选表示“持续疼痛”的C项aches。（词汇辨析题。sore,hurt和ache都可以用作名词，表示疼痛，但有所区别：sore表示（一碰就疼的）痛处或疮口，精神上的痛处，伤心事；ac
