词汇突破
disease [dɪˈziːz]
n. 疾病，病害；弊病，恶习
v. 传染，使……有病
toll [təʊl]
n. （道路、桥梁等的）通行费；<美>长途电话费；（事故、灾难、战争等的）伤亡人数；严重的不良影响；（缓慢的）钟声
v. （缓慢地）敲（钟），鸣（钟）；鸣钟告知；收取（桥梁或道路的）通行费
结构分析本句的主干是 Stronger public-health systems would help fight such diseases as tuberculosis and malaria。which reduces global GDP by $ 12 billion a year 和 which takes an even bigger toll 皆为非限制性定语从句，分别修饰先行词 tuberculosis 和 malaria。tuberculosis 指肺结核，malaria 指疟疾。
