你好

Because its leaves remain green long after being picked, rosemary became associated with the idea of remembrance.
采摘下的迷迭香树叶常绿不衰，因此人们把迷迭香树与怀念联系在一起。

because 引导原因状语从句 

Because its leaves remain green long after being picked

主语：Its leaves

谓语： remain

表语：green

状语：long

时间状语：after being picked

Most substance contract when they freeze so that the density of a substance’s solid is higher than the density of its liquid.
大多数物质遇冷收缩，所以他们的密度在固态时高于液态。

主语：Most substance

谓语：contract

时间状语：When they freeze (they主语，freeze谓语）

so that 引导 结果状语从句

so that the density of a substance’s solid is higher than the density of its liquid.

主语：the density of a substance’s solid (of a substance’s solid定语，修饰 the density)

谓语：is

表语：higher

比较壮语从句：than the density of its liquid. （主语 the density, 定语 of its liquid. 谓语is省略）

祝你学习进步，更上一层楼！

不明白请及时追问，满意敬请采纳，O(∩_∩)O谢谢~~

Answer 2

because后面引导原因状语从句，解释rosemary...renenbrance。
后半句中when they freeze是时间状语从句，说明前面大多数物质收缩的时刻；so that后面引导的是结果状语从句，因为前面说的“大多数物质遇冷收缩”导致后面“他们的密度在固态时高于液态”，这里还有一个比较级（A） higher than （B），意思是A比B更高
