prep里的语法问题，快考试了，希望大家帮忙（三）

对第二点解释有点疑惑：

1. 现在分词做伴随状语，应该要修饰主句谓语啊，表示动作和主句的动作同时发生。
  

例如： OG 10th 259. Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.
(A)bringing  (B)and brings  (C) and it brings (D)and it brought (E) and brought

Choice A is best. The "-ing" (present participle) form intro­duces action that is simultaneous with the action of the main clause; i.e., bringing indicates that the number of wild birds became 34 when the sea eagles left their nests.（现在分词表伴随，说明这个动作和主句的动作同时发生）

这里的bringing 就是要表示和  left their nests  同时发生的动作，而不是修饰它前面直接接的名词this summer。
 

如果按照这个推理的话，题目中：

In the past several years, astronomers have detected more than 80 massive planets, most of them as large or larger than Jupiter, which circle other stars.

去掉插入语most of them as large or larger than Jupiter， 如果后面用 circling做伴随状语，他只能伴随 have detected 的动作，而不能修饰 plants 。。

这样的逻辑意思就不合理了，我就是这样排除了正确答案，

2. 关于 which circle 存在歧义到底是修饰 Jupiter 还是 planets的问题，从句子意思上看应该是修饰planets，但是用 which circle 用复数的谓语动词已经明确的指出了他的修饰对象，不存在歧义。而且这种跳跃修饰在OG 10th 也不少见：

OG10th 109. Legislation in the Canadian province of Ontario requires of both public and private employers that pay be the same for jobs historically held by women as for jobs requiring comparable skill that are usually held by men.
(A)  that pay be the same for jobs historically held by women as for jobs requiring comparable skill that are
(B)  that pay for jobs historically held by women should be the same as for a job requiring comparable skills
(C)  to pay the same in jobs historically held by women as in jobs of comparable skill that are
(D)  to pay the same regardless of whether a job was historically held by women or is one demanding comparable skills
(E)  to pay as much for jobs historically held by women as for a job demanding comparable skills
Choice A is best. In choice B, should is illogical after requires, or at least unnecessary, and so is better omitted; in choices B and E, job does not agree in number with jobs（尤其要注意，在并列中，单复数也要对应，一致）;
and in choices B, D, and E, the wording illogically describes the comparable skills rather than the jobs as being "usually held by men." （用定语从句修饰就没问题, 因为主谓一致的数的要求）这里的that are可是不能省略的!!!

想来想去只能是认为 circling 就是做分词跳跃修饰 planets, 而不用理会中间的插入语，在这里 circling 和 which circle 都可以，并不能用这个判断。

那用来排除的依据只能是 mostly / most of them 的逻辑意思的差别了。 

这题真烦，期待NN 来进一步解释！
