987 SECTION 19-12

The Olympic Games helped to keep peace among the pugnacious states of the Greek world in that a sacred truce was proclaimed during the festival’s month.

(A) world in that a sacred truce was proclaimed during the festival’s month

(B) world, proclaiming a sacred truce during the festival’s month

(C) world when they proclaimed a sacred truce for the festival month

(D) world, for a sacred truce was proclaimed during the month of the festival（C）

(E) world by proclamation of a sacred truce that was for the month of the festival

请教为什么B不对? 还有什么时候用从句什么时候用V+ING?

现分在句尾，一般作状语修饰主句，所以在这里逻辑不合理；

哈哈，至于定从和现分的区别，楼主的问题实再太大，实再不容易轻易回答，不过一般情况下，针对作定语这个方面，强调ongoing的东东用现分，法律、规定等等也用现分。

对于现在分词作状语,就属于限定性修饰,必须隐含一种意思:”还有另外一部分修饰的东东不包含在内

而从句则是非限定性修饰.大部分分词和定语从句的修饰可以通过限定和非限定来搞定!

难道就没有人质疑c答案里面的they的用法吗，请问如何分辨they不能指代olimpic games，晕

Please help, NN

248. By offering lower prices and a menu of personal communications options, such as caller identifica­tion and voice mail, the new telecommunications company has not only captured customers from other phone companies but also forced them to offer competitive prices.

(A)  has not only captured customers from other phone companies but also forced them

(B)  has not only captured customers from other phone companies, but it also forced them

(C)  has not only captured customers from other phone companies but also forced these companies

(D)  not only has captured customers from other phone companies but also these companies have been forced

      not only captured customers from other phone companies, but it also has forced them

C, the best choice, correctly uses the parallel construction has not only x 'd but also y 'd and avoids ambiguity of reference by using these companies rather than them. In A, B, and E, the referent of the pronoun them is ambiguous; because them appears to be parallel to customers, the illogical suggestion is that the new telecommunications company has forced customers to offer competitive prices. Choices B and E may also be faulted for the improper insertion of it to refer redun­dantly to the new company. Finally, E is not parallel in verb tense with captured... has forced. Choice D does not main­tain parallelism, unnecessarily shifting from active (company not only has captured) to passive (but also these companies have been forced).

这到题目就是明显的对比，注意B选项里面的them，就被认为是可以同时修饰前面两个复数名词，而被认为具有歧异

再来一题没有问题的

227. Judicial rules in many states require that the identi­ties of all prosecution witnesses are made known to defendants so they can attempt to rebut the testi­mony (证词(尤指在法庭所作的), 宣言, 陈述), but the Constitution explicitly requires only that the defendant have the opportunity to confront an accuser in court.

(A)  that the identities of all prosecution witnesses are made known to defendants so they can attempt to rebut

(B)  that the identities of all prosecution witnesses be made known to defendants so that they can attempt to rebut

(C)  that the defendants should know the identities of all prosecution witnesses so they can attempt a rebuttal of

(D)  the identities of all prosecution witnesses should be made known to defendants so they can attempt rebutting

making known to defendants the identities of all prosecution witnesses so that they can attempt to rebut

这题选B，也是they前面有两个可以作为指代的复数名词，请nn指教，什么时候有歧异，什么时候没有歧异，怎么判断。

1，如果是说根据逻辑来判断的话，那么og248可以很容易的判断出来，them指代other companies，因为后面有to offer competitive prices。然而ets仍然认为有修饰歧异...

2，如果说优先修饰主句主语的话，那么这到题目可以证明修饰的是靠近修饰

3，如果说不是靠近修饰的话，那么如何判断that修饰问题？
