[求助]OG104

104. The diet of the ordinary Greek in classical times was largely vegetarian--vegetables, fresh cheese, oatmeal, and meal cakes, and meat rarely.

(A)     and meat rarely

(B)         and meat was rare

(C)     with meat as rare

(D)     meat a rarity

(E)         with meat as a rarity

The best answer here must qualify the statement made in the main clause. The diet... was largely vegetarian: it cannot be treated as part of the list of vegetarian foods. In other words, the best answer must logically and grammatically attach to the main clause when the list is omitted (首先从结构上判断). Choice A fails this test: The diet. . . was largely vegetarian, and meat rarely. D fails also, because it lacks a function word such as with to link it to the main clause. The wording of choice B is imprecise and ambiguous--for example, it could mean that meat was scarce, or that it was not well done or medium. Choice C is unidiomatic. Clearly phrased, grammatically linked, and idiomati­cally sound, choice E is best. (紧密型独立主格结构)

这里的解释有点不明白：The best answer here must qualify the statement made in the main clause. The diet... was largely vegetarian: it cannot be treated as part of the list of vegetarian foods. In other words, the best answer must logically and grammatically attach to the main clause when the list is omitted (首先从结构上判断).

我想了半天也没看懂，是不是关于句子结构该如何处理的？fficeffice" />

我认为snazzy和tianwan的看法比较正确，这里with结构引导的是独立主格with+n+prep，E中的as作为介词，解释为：作为；rarity －名词，解释为：稀有之物

个人认为E中的as可以省略，形成snazzy所谓的with+n+n的独立主格结构，但是保留对句意的清楚表达更好；同时需要指出，as作为介词，所以后面不能跟形容词，所以C表达错，而且C中的rare意思复杂，容易引起歧义；

第一次听说这个名词。能不能请你给个定义？是不是说紧密连接型独立主格的内容必须和主句内容联系紧密且必须由with开头？那么n.+n.型的独立主格呢？

我觉得这道题D和E都是独立主格结构，但是因为中间有长长的一串插入语，把主句与独立主格远远地分开了，所以加上with是为了明确meat as a rarity在句中的作用——独立主格，以避免读者将其理解为插入语的并列成分。如果把插入语删去的话，D 和E都应该是对的。

请NN斧正！

这里的独立主格是对主句的修饰和补充，而不是对vegetarian的说明。

所以，用独立主格的话，就必须用WITH＋。。 否则就容易产生修饰对象的混淆。
