再问大全794题，以前的讨论有未尽之处

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

我看了以前的讨论，问题主要集中在C和D上：首先，有人认为此句用因果状语从句（for)比时间状语从句（when）好；其次，被动语态是否一定要明确动作的施动者；第三，C中的they语法上指代句子的主语games，而逻辑上只能指代states，这样以来是不是有引起歧义之嫌。大家在以前的讨论中只是提出了这些疑问，但没有一个明确的结论，请NN们帮忙分析一下吧，为什么是D而不是C，先谢了！

C的when时间状语从句很不方便修饰help，主句唯一的动词，同时they如楼主所言有歧义之嫌；proclaim a sacred truce for the festival month实际上说这个truce只是for the month，似乎扭曲原意（原意应该是，在这个聚会期间truce被达成）。

D唯一的问题就是被动——但不算是致命错误

1. Olympic Games 是单数，不是复数。

   C. they 指代 states

2. C,D 表达的意思不同

C. proclaim a truce For the festival

为了 festival 而 proclaim a truce，

目的明确，就是为了festival才休兵的 （e.g.仅在festival期间休兵)

D. for a truce was claimed during the festival

在 festival 期间休战 （e.g.festival 30天，休兵3天吧）

btw, OG doesn't promote 'for' as a reasoning conj.

本题的考点应该是搞清楚到底是谁“proclaime the truce”！！

根据“pugnacious states ”---好斗的城邦，当然停战协议是由stateds 发出的,所以：

A  "truce was proclaimed" 没有明确动作的发出者

B  "proclaiming"由主语olympic games发出（另：the Olympic Games应该是单数）

C " when they proclaimed a truce" 明确是states 提出,所以为正确答案

D 同A

E " help sb by proclaimation" 由主语olympic games发出
