OG12 SC 137 仅利用“逗号”，就可以排除所有错误答案，求验证！

我又想了下，这个问题好像是语法的一个逆命题，鉴于的CR太差，楼主的说法我也不知道对不对，坐等高手验证。我先说下正方向的理解。在语法中，当2个句子要连起来时，中间就需要有个conj,就是我们常说的FANBOYS，或者是subordinators，否则就是run-on sentences。所以我们常见的句子就是S1+V1+O1，and S2+V2+O2。manhattan也说到，当看见“逗号+and”的情况，请停下来检查下是否是如下两种情况（1）一串list，A，B，andC。（2）就是2个句子连起来的，就我上面说的。
至于能不能因为缺少相同的主语而判断错误。。。我再去看下manhattan。

你理解错了，我理解的“逗号法则”中心不是“是否缺少相同的主语”，而是有and，要么不加逗号，可以不要重复主语：要么加逗号，但必须补出主语（这里主语就不必非得是相同的了，看句子意思了，也可以说I went to school, and he stayed at home.）

刚好有了个例子，你看看一下，是不是可以做为 逗号+and+V可以不重复主语的例子：
Construction of the Roman Colosseum, which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, was completed a decade later, during the reign of Titus, who opened the Colosseum with a one-hundred-day cycle of religious pageants, gladiatorial games, and spectacles.

A.    which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian,
B.    officially known as the Flavian Amphitheater, begun in A.D. 69, during the reign of Vespasian, and
C.    which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, and
D.    officially known as the Flavian Amphitheater and begun in A.D. 69, during the reign of Vespasian it
E.    officially known as the Flavian Amphitheater, which was begun in A.D. 69, during the reign of Vespasian, and

我觉得这里是因为差了一个时间状语“during the reign of Vespasian”，不得不在该时间状语前面后面加了逗号。把时间状语提出来，都逗号都去掉，就是“begun in A.D. 69 and was completed a decade later ”，就看到加and的必要性了吧。状语什么的，都是GMAC拿来迷惑我们的，都提出后去理解句子结构比较清晰。我是这么理解的，还是坚持我的“逗号法则”。

这里如果要加it，就变成“begun in A.D. 69 ，and it was completed a decade later ”，多余了吧，而且指代模糊。所以，去掉时间状语后的结构必定是“begun in A.D. 69 and was completed a decade later ”。
