So large is the Pacific, covering 30% of the planet's surface, that the additional energy generated by its warming is enough to touch off a series of weather changes around the world.
太平洋是如此之大,覆盖了地球表面的30%,以至于其变暖所产生的额外能量足以引发全球一系列的天气变化。
so...that 结构可以通过倒装来强调程度。当 so + 形容词/副词置于句首时,主谓必须倒装。识别要点:(1) 句首出现 "So + adj./adv.";(2) be动词或助动词提到主语之前;(3) 句中有 that 引导结果从句。
还原步骤:将 "So large is the Pacific" 还原为正常语序 "The Pacific is so large",再连接 that 从句,整句变为 "The Pacific is so large that..."。倒装前后语义相同,倒装形式突出强调程度。
本句中 "So large is the Pacific" 将 "so large" 前置并触发倒装 "is the Pacific",强调太平洋面积之大(覆盖地球表面30%),大到足以引发全球天气变化。识别倒装是理解句子主干的前提。
