22、million people were living with HIV in 2017.”和“Now there is no cure for HIV/AIDS.”可知,本段说明了全球HIV病毒感染的严峻现状。故选A。B项“非洲的快速发展”;C项“治疗艾滋病的切实可行的方法”;D项“联合国所做的努力”。2.B细节理解题。根据第五段第一句“They say the easiest and most cost-effective way to use the rice will be to make it into a cream to be put on the skin.”可知,科学家们认为最

23、简单且最节约成本的方式就是把这种大米加工成膏,涂在皮肤上。故选B。A项“通过把它转化成蛋白质”;C项“通过把它附着在HIV病毒上”;D项“通过把它添加到口服药物中”。3.D推理判断题。根据最后一段最后一句“The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to human bodies.”可知,科学家们认为还需要做进一步

24、测试,以确保基因工程过程的安全性。故选D。A项“它不会产生危险的化学物质”,B项“它产生了危险的化学物质”,由文章最后一段中的最后一句可知,是否产生有害的化学物质是有待确定的事;C项“它是为发达国家设计的”,由文章的第三段和第四段的首句可知它是为发展中国家设计的。4.D推理判断题。根据主旨段第一段提到的“According to a recent study, a new kind of genetically modified rice can prevent infections of HIV.”可知,文章主要介绍了一项科学研究,该研究与一种可以防止感染HIV病毒的新型转基因大米有关,其话

25、题与健康相关。由此可以推断,文章可能是选自健康杂志。故选D。A项“一本生物教材”;B项“一本急救手册”;C项“一个社交网络页面”。三、阅读七选五1E根据下文的介绍可知，作者开始讲述“first aid”这个表述的起源和发展过程。E项内容(然而，“急救”从何而来，谁是“急救者”？)承上启下，符合题意。故选E项。2D根据上文中的“The first recorded history of first aid dates back to 1099. . ”可知，本段举例说明了“first aid”这个表述的起源。所以，D项(他们是第一批经过急救训练的人。)是对本段的总结。故选D项。3B根据后面一句

26、“He suggested training ordinary people in what was called premedical treatment”可知，此处要说明谁提出“first aid”的想法。关键词He与B项中的“an army surgeon”相对应。故选B项。4G根据文章结构，本段继续讲述的是first aid的发展历程。后文讲，第一堂公共急救课程在1878年伦敦开设，所以G项(在1878年伦敦开始出现“first aid”)，符合语境。故选G项。5F根据本段的第一句“Modern­day prehospital treatment of the sick an

27、d injured. ”可知，现代急救发展迅速，此处点明其实质与11世纪时还是一样的。故选F项。四、语法填空1. totally。考查副词。此处应填total的副词形式修饰形容词different。2. was used。考查时态和语态。此处是句子谓语动词, 由in the 1960s判断为一般过去时, 主语The term和use之间是被动关系, 故用一般过去时的被动语态, 主语是单数, 故be用was。3.researching。考查非谓语动词。分析句子结构可知, 此处考查while引导的状语从句的省略, 完整的句子应是She first came across this phenomen

28、on while she was researching North American children living in India. 当时间/条件/让步状语从句的主语与主句主语一致, 且从句有be动词时, 可省略从句的主语和be动词, 省略之后是while researching North American children living in India。4.their。考查代词。此处应用they的形容词性物主代词修饰名词experience。5. difficulties。考查名词的数。由many判断此处用difficulty的复数形式。6. to。考查介词。此处考查短语adapt

29、. . . to. . . “使适应”。7.to develop。考查不定式。此处考查固定句型find it+adj. + to do sth. “发现做某事怎么样”, 其中it是形式宾语, to do是真正的宾语。8. easier。考查形容词比较级。根据than判断此处应用easy的比较级作为is的表语。9. where。考查定语从句。分析句子结构可知, 此处是定语从句关系词, 先行词the country在从句中充当地点状语, 应用关系副词where。10. or。考查并列连词。句意: 她对当前的电视节目或时尚潮流一无所知。根据语境可知, 此处是并列关系, 意为“或者”, 应使用连词or。第12页（共12页）
