  1. Although most people think of Egyptian papyrus as the earliest paper, during the Han Dynasty, the Chinese developing a process to create paper from individual plant fibers that was much closer to techniques used in modern papermaking.

  (A) the Chinese developing a process to create paper from individual plant fibers that

  (B) the Chinese developing a process and creating paper from individual plant fibers that

  (C) the Chinese that developing a process to create paper from individual plant fibers, it

  (D) the Chinese developed a process to create paper from individual plant fibers, it

  (E) the Chinese developed a process to create paper from individual plant fibers that

  【分析】

  A, B都不是完整的句子。Although后面是个完整的从句,但在从句后面

  有主句。虽然主语Chinese出现了,但没有谓语动词与之相配。我们在前面提到过,分词结构式不能做谓语的,即developing不能单独做谓语。划线部分的后面是that引导的定语从句,整个句子还是没有从句。所以A, B排除。

  C的问题是,如果把“it was much closer…”作文主句和although从句连接,句意上无法成立。同时,“the Chinese developing…”应当作为一个结构来看待,而“名词 + doing”的结构是SAT认为的不符合简洁性的要求。

  D的问题是run-on, 整个句子里有三个完整的小句子,却只有although一个连词。

  正确答案: E

  2. Although the dancers were nervous at the beginning of their performance, having shown remarkable ease as the performance progressed.

  (A) having shown remarkable ease as the performance

  (B) once they have showed remarkable ease when the performance had been

  (C) but showing remarkable ease as the performance

  (D) they showed remarkable ease as the performance

  (E) but they showed remarkable ease when the performance

  【分析】

  Although引导一个从句,从句在逗号处结束,那么逗号后应该是一个主句。

  A选项没有主句,应该是主句的内容写成了个不完整句子,应排除。

  在B选项中once是个连词,它后面的句子应该是从句,同时,when也引导了一个从句。区分主句和从句的唯一标准就是:紧跟在连词后面的句子为从句。在上述三个从句中,有三个连词,所以后面都是从句。

  C首先没有主句;其次,用了although就不能用but了;同时,progress不能使用被动语态。

  E的问题是although和but同时使用,属于连词重复。同时,E也没有主句。

  正确答案:D

  3. Both Cinderella and Snow White being dependent on a prince to rescue them from unfortunate circumstances.

  (A) Both Cinderella and Snow White being dependent on a prince to rescue them from unfortunate circumstances.

  (B) Both Cinderella and Snow White were dependent on a prince to rescue them from unfortunate circumstances.

  (C) Dependent on a prince to rescue them from unfortunate circumstances being both Cinderella and Snow White.

  (D) Unfortunate circumstances were what both Cinderella and Snow White were dependent on a prince to rescue them from.

  (E) Dependent on a prince to rescue them from unfortunate circumstance was both Cinderella and Snow White.

  【分析】

  A和C为不完整句型,因为没有谓语动词。C采用了倒装结构,真正的主语在谓语动词后面。在C里,只能是being做谓语动词,而being是个分词,不是谓语动词。

  E是个结构正确的倒装句,但主谓不一致。真正的主语是both Cinderella and Snow White,是复数概念,所以was应改为were.

  D选项表述过于复杂,不符合简洁原则。

  正确答案: B
