for so large an ocean it has very few islands; also,it is the world's saltiest ocean.
问题描述：
for so large an ocean it has very few islands; also,it is the world's saltiest ocean.
如题,第一for在这里做什么解释?
第二：the world's salties （课本上翻译是：世界上含盐分最多的大洋）为什么要这样用,还有其它方式吗?特别是saltiest 这个词.
答
for so large an ocean=== for a large ocean like this 对于这样一个大洋来说
for这里是：对于的意思
salty 形容词,咸的,*：saltiest
对于这样一个大洋来说,（洋中的）岛屿很少,而且它也是世界上含盐分最多的大洋（最咸的洋）
