正确答案是1 D 2C 3D 4 D 这四题考的是SAT中的同位结构,是SAT比较青睐的一个考点,
在SAT考试中,设计的同位结构一般比较复杂.
例：Ancient Chinese people believed that rice has therapeutic function,a belief that has been dominant in Chinese culture.
这个句子可以看做是一种特殊同位结构的运用.在一个完整的句子后面,往往用一个抽象名词来概括逗号前面句子的内容,然后再用一个分句或结构对该抽象名词进行进一步修饰说明.这样,这个抽象名词和前面的整个句子（有时是句子的某一个重要成分）构成了一种同位关系.
在SAT考试中,看到这一类同位结构的选项,一般可以认定是正确选项.
例：I failed my exam and lost my girlfriend,a situation that I had never encountered in before.
在上句中,用a situation对I failed my exam and lost my girlfriend进行概述,在situation后用一个从句对它进行进一步修饰,从而使situation和前面的完整句子构成一种特殊的同位结构.
