介词放句首其逻辑主语到底是不是句子主语？困惑中。。。。下面有两个题有点不明白，求解答~~~谢谢大家啦~
旧prep66 ：In addition to her work on the Miocene hominid fossil record, Mary Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstakingly documenting East African cave paintings.
(A) Leakey contributed to archaeology with her discovery of the earliest direct evidence of hominid activity and painstakingly documenting
(B) Leakey contributed to archaeology by her discovery of the earliest direct evidence of hominid activity and by painstakingly documenting
(C) Leakey was a contributor to archaeology with her discovery of the earliest direct evidence of hominid activity and with her painstaking documentation of
(D) Leakey's contributions to archaeology include her discovery of the earliest direct evidence of hominid activity and her painstaking documentation of
(E) Leakey's contributions to archaeology include her discovering the earliest direct evidence of hominid activity and painstaking documentation of
C. 该选项采用了Mary Leakey was a contributor…with x and with y句型，没有明确Mary Leakey的贡献与x/y之间的关系，be a contributor所表达的意思与原句不同。比如说，I am a singer with afive-year old kid. 我是一个有个五岁小孩的歌手，但是有小孩和是歌手之间并没有直接联系。换到这个句子当中来，Mary Leakey was a contributor with a five-year old kid.同理成立，但是kid和contributor之间没有联系，并不是Mary有个五岁小孩所以就是贡献者。同理理解该选项的问题。相比之下，D选项直接明了的说，Mary Leakey的贡献就是她的发现以及对洞穴画的记录和描述，清晰直接的说出了句子内容之间的联系。所以，相比之下，C选项不如D
D. 正确。这里面没有提到介词防句首的逻辑主语问题。。
旧perp 50：With no natural predators and expanses of green suburban neighborhoods that allow no hunting, wildlife officials estimate the New Jersey deer population to have grown to exceed 175,000.
(C) With no natural predators and with expanses of green suburban neighborhoods where there is no hunting, the deer population in New Jersey, wildlife officials estimate, has
正确答案 C
句子结构：With… and with…, the deer population…, has grown…
并列的介词短语在句首作状语，逻辑主语是主句主语deer population。
考点：逻辑表达、简洁有效
1) 逻辑表达，介词短语位于句首时，其逻辑主语等于句子主语；主谓搭配逻辑要合理。
2) 简洁有效，without连接并列的名词时，要注意其修饰对象是否清楚，是否合理。
这两个题都是以介词在句首的，如果按照第二题解释的解释，那个么上面那个题是不是也可以按照介词逻辑主语为句子主语的逻辑来排除A B C?第一题解释中没有提到按照介词逻辑主语来排除。。。而是根据句子结构和疑似来解释的。。。不理解中，求NN解答~~~



还有一个关于形容词和过去分词放在名词后面的修饰歧义的问题、、、

旧prep 105. (29961-!-item-!-188;#058&004575)
2001 proved to be the automaker's first losing year since 1992, when the company had lost $7.4billion, which was primarily because of almost $7 billion in accounting charges.
(C) when the company lost $7.4 billion, primarily because of

C. 正确。这个后面的primarily because of不会有修饰2001年得亏损的嫌疑么？就像一般的分词放在举手有修饰他前面的名词和修饰整个句子的歧义一样。还是说过去分词或者形容词放在名词后面当修饰成分的时候就不会有这样的歧义？
下面这题以及他的正确选项，called 和 located 都修饰fingerlike poking，有没有可能修饰which所指代的cell？

Taste buds are onion-shaped structures with between 50 and 100 taste cells, each of them has fingerlike projections poking through the opening located at the top of the taste bud called the taste pore.

(C) which has fingerlike projections poking through the opening, called the taste pore, located at the top of the taste bud
