Over the past decade, the focus has been on climate change—how the warming of the Earth from greenhouse gases is leading to conditions that worsen fires.(英二2017年 text 4)
例句分析:Over the past decade作时间状语,the focus has been on climate change是主句,单破折号后面对气候变化做出具体解释,在how引导的句子中,the warming of the Earth from greenhouse gases作主语,is leading to作谓语,conditions作宾语,而that worsen fires是一个定语从句修饰先行词condition,其中that在定语从句中作主语。如果先行词是物的话,定语从句的引导词可以用that,也可以用which。如果先行词是人的话,引导词可以用that,也可以用who。
重点单词:decade十年,climate气候,greenhouse温室,worsen恶化,lead to导致。
参考译文:在过去的十年里,焦点一直集中在气候变化上——温室气体导致的地球变暖是如何导致火灾恶化的。
