[句式分析]　此句是____句。Despite，or perhaps...in recent years作____，其中the world has faced in recent years是____从句，修饰the epidemics；the fact之后的that 引导______从句。 [自主翻译] 复合 状语 定语 同位语 尽管(或者是因为)近年来全球爆发了流行病，世界各国政府都已经强调，要对流行病进行彻底和系统的医学研究，以便尽快找出原因并找到治疗方法。 33004 非典疫情始于2002年广东省的一例肺部疾病，后蔓延到加拿大、越南和新加坡，并一直持续到2003年。科学家对这种新型疾病感到困惑，对SARS病毒进行检测，以期了解该病与致病原因的更多信息。 非典的感染率不断上升，在爆发期九个月内感染了约8000人。非典疫情结束后，科学家们一直在试验各种治疗手段，以防止未来疫情再爆发。 Para 7： The SARS epidemic began in 2002 with a case of lung disease in Guangdong Province. It spread to Canada, Vietnam and Singapore and lasted until 2003. SARS was examined by scientists, who were confused by this new disease and wanted to learn more about it and its causes. Infection rates went up steadily, and in the course of the outbreak, about 8,000 people were infected over nine months. Since the end of the SARS epidemic, scientists have been doing trials on treatments to prevent any future outbreaks. 蔓延到 非限制性定语从句 n.感染 go up 增长；上升 在…过程中 course n.过程；课程 v.感染 n. 试验；审判 Para 8：Then, from 2013 to 2016, there was the most widespread outbreak of the Ebola Virus Disease (EVD) in West Africa, which resulted in a major loss of life in a number of west African countries. 11,310 deaths were officially recorded, but the actual number of deaths is probably much higher. The virus was extremely infectious and the survival rate was as low as 30% in some areas, indicating that very few people got over it. 随后，2013年到2016年间，西非爆发了大规模传染病——埃博拉出血热(EVD)，夺去了这一地区多个国家的很多人的生命。官方统计的死亡人数为11310 人，而实际死亡人数可能要更高。该病毒传染性极强，一些地区的存活率低至30%，也就是说很少有人能康复。 非限制性定语从句 重大损失 Adv. 官方地 a.实际的 [伴随状语] indicate v. 表明；暗示；象征 get over康复 尽管(或者是因为)近年来全球爆发了流行病，世界各国政府都已经强调，要对流行病进行彻底和系统地医学研究，以便尽快找出原因并找到治疗方法。这需要各个国家的共同努力，因为全球各国之间的团队合作才能拯救生命。 Para 9：Despite, or perhaps because of, the epidemics the world has faced in recent years, governments worldwide have underlined the fact that they want thorough and systematic medical research on epidemics to get at the causes and come up with cures as soon as possible. Countries will need to work together to do this because teamwork among nations across the globe can save lives. 省略that的定语从句 状语 同位语从句 a. 彻底的；全面的 a. 系统的 查明 V.强调 10 11 Part 1(Para. 1) A.
