Answer 1

1.答案是D.你答案错了.When (the biggest ocean is）compared with the size of the whole earth,the biggest ocean does not seem bit at all.这里省略了从句的主语the biggest ocean,和be动词is,注意这种省略有个前提,从句和主句的主语是同一个.被动关系是因为固定词组：compare sth. with sth. 所以sth. be compared with sth.
2.这里过去分词做定语,相当于which was known as 3M. 而being done, 现在分词的被动式,强调正在进行的时态意义,显然不合适.
3.选B.attract和主语the girl 之间是被动关系,所以用过去分词做状语.C选项不定式做状语在中学阶段只表目的和结果,与句意不符.D选项是主动的,这就错了,而且having done做状语强调动作的先后顺序,即having done的动作一定发生于句子里的动作之前,这里也不合适.
这句话意为：被大自然的美丽所吸引,来自伦敦的女孩决定在农场多呆上两天.
