都说托福阅读部分文章有难度，其实这种难度很多时候来自于文章中的长难句。这些句子结构复杂内容繁多，考生如果无法快速正确地看懂它们必然会影响对文章的理解和解题效率。所以下面小编就为大家带来托福阅读 100 个长难句的精选汇总和深度解析，为大家提供学习指点和启发。
托福阅读 100 个长难句实例分析原句案例：

结构划分：
( In order for the structure ) ( to achieve the size and strength necessary to meet its purpose ) , architecture employs methods of support that, ( because they are based on physical laws ) , have changed little since people first discovered them —— ( even while building materials have changed dramatically. )

深度分析：
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。
