In order for the structure to achieve the size and strength necessary to meet itspurpose, architecture employs methods of support that, because they are based on physical laws, have changed little since people first discovered them——evenwhile building materials have changed dramatically.(44)

修饰一：(In order for the structure)，介词短语

修饰二：(to achieve the size and strength necessary to meet its purpose)，非谓语做形容词性修饰structure

修饰三：(because they are based on physical laws)，插入语，插入语记得先跳过去，断句别出问题，that和have changed是在一起的。

修饰四：(that have changed little sincepeople first discovered them.从句修饰support

修饰五：(even while building materials have changed dramatically. )，从句

括号外面的是主干：architectureemploys methods of support，注意support这里是名词。

参考翻译：为了使结构达到必要的大小和强度去满足它的目的，建筑学上使用了一些支撑的方法，因为这些方法都是基于物理定律，所以尽管建筑材料已经发生了巨大变化，这些方法却自人们发现它们以来就没有什么变化。
