a violent eruption can blow the top few kilometers off a mountain, scatter ash practically all over the globe and hurl rock fragments into stratosphere to darken the skies a continent away. 这个句子里的 top 和 away 怎么理解呢? 做什么成分?
关于对象状语和方向状语总搞不清楚,能否请专家具体总结一下。举个例子:I have a question for you all,这个for you all是对象状语吗?the planet will be exposed to climate risks.这个to climate risks是主补还是方向状语还是对象状语?
