因为贫困，疟疾等完全可预防的疾病每年要杀死 600,000人；许多人太穷以至于买不起药品和防虫蚊帐，而政府在杀灭携带病菌的蚊子或遏制和治疗传染病暴发方面做得也太差。
And it is why an entirely preventable disease like malaria kills 600,000 people each year; many are too poor to buy drugs and bed nets, while governments are often too poor to eradicate the mosquitos that carry the disease or contain and treat outbreaks when they occurs.
