句子讲解:
1.Traces of iron in granite is evidence that rock, pushed up from 15 miles below the surface, tilting the Flatirons.
【结构简析】咋一看,咦,怎么有三个动词在句子中。其实,后面的两个是非谓语动词,"pushed" 和"tilting"中首先讲讲"pushed",它是过去分词,用来解释说明"rock"从哪里来。"tilting"是现在分词,做伴随状态,岩石升上来的同时也就倾斜成烫斗状。
【参考译文】花岗岩中的铁元素向我们证明,岩石是从地表下的15公里升起来的,同时倾斜成了平顶脊(熨斗形岩石)。
2. What we know is that at the time of this grand uplift, on the western margin of North America, ocean crust, and Oceanic Plate, was subducting beneath the North American Plate.
【结构简析】这是一个由what引导的主语从句,后面接着"that"的表语从句。句子中插入的部分太多,导致Daisy刚开始理解错了.后来,多看几遍后,知道了原来"and"的理解非常关键,它不是 "on the western margin of North America, ocean crust, and Oceanic Plate"整个的作为插入语,而是" ocean crust, and Oceanic Plate, was subducting beneath the North American Plate. "。
【参考译文】我们所知道的是,这段时间内在北美的西部边缘地带,海洋地壳,以及海洋板块,从北美板块下大面积地隆起。
