As a result of drought and heat,more than 500 wildfires have raged out of control,smothering Moscow in smoke and threatening several nuclear facilities.Russia's government has banned wheat exports,sending world grain prices soaring.
【正确答案】：由于干旱和高温，500余处野火迅速蔓延，失去控制，把莫斯科笼罩在令人室息的烟雾中，并威胁到几处核设施。【解析】原句是主谓结构的简单句，as a result of..在句中作原因状语；out of control修饰谓语动词raged，汉译时变状语为谓语；smothering Moscow in smoke..…在句中作结果状语，汉译时将smothering译作形容词修饰smoke,而将宾语Moscow提前。
