英语语法问题
because the vertical pressure gradientts within the blood vessels are counteracted by similar pressure gradients in the surrounding water,the distribution of blood throughoutthebodyof sea snakes remains about the same regradless oftheir orientation in space,provided they remain in the ocean.
这最后一句provided they remain in the ocean 这个语法怎样分析,动词加一个代词加动词加一个介词短语,这是什么结构?
(it's) provided [ (that) they remain in the ocean ]
所以后面自然是一个 句子
但是是一个 子句
整句就是 动词分词 加 that子句
形成一个 分词结构 的 条件句
还不清楚再问喔
