一道SAT (OG01) Trees are able to collect large amounts of wate

原句 in some areas as much as thirty inches annually 是对collectlarge amounts of water from fog （从雾中收集到大量的水）的进一步说明,等于 in some areas collect the water fromfog as much as thirty inches annually（在有些地区从雾中每年收集到差不多三十英寸的水）的省略.
依照上述办法,也可以把其他选型补充完整,
B. in some areas to collect the water from foghaving thirty inches per year （在有些地区从雾中每年收集到（正好）有三十英寸的水）C. in some places to collect the water fromfog collecting about thirty inches per year annually （在有些地区从雾中每年收集到有三十英寸左右的水）D. collecting the equal water from fog ofthirty inches annually in some places （在有些地区从雾中每年收集到与三十英寸相等的水）E. which (指代 the waterfrom fog) in some areas amounts to thirty inches collected annually （在有些地区从雾中每年收集到的水总计达到三十英寸）【amounts (to) 是从句的谓语动词,意思是“总计达到/等于/实际上是”】
原句的的 as much as 指“多达”或“差不多”,B 项的分词 having 指“拥有”,C 项的介词 about 指“大约”或“…的左右”,D 项的名词短语 theequal of指“等于”,E 项的谓语动词 amountsto 指总计达到…的数量.可见,其他选项都改变了原句的意思.
