请高手指教

1.        A collection of 38 poems by Phillis Wheatley, a slave, was published in the 1770’s, the first book by a Black woman and it was only the second published by an American woman.C

(A) it was only the second published by an American woman

(B) it was only the second that an American woman published

(C) the second one only published by an American woman

(D) the second one only that an American woman published（E）

(E) only the second published by an American woman

此题为语法大全中的一题，答案为E，但我倾向于C，不知各位高手意见，请指教。

1.        A peculiar feature of the embryonic mammalian circulatory system is that in the area of the heart the cells adhere to one another, beating in unison and adopting specialized orientations exclusive of one another.

(A) beating in unison and adopting

(B) they beat in unison while adopting

(C) beat in unison, and adopt

(D) beating in unison yet adopting（D）

(E) even though they beat in unison and adopt

为何选D，不选C，D与A有何差别？

(A) it was only the second published by an American woman

在这个选项里, it was 重复了主语，因此是一种冗赘的表达方式。

"only也可以修饰动词，从理论上讲它应紧挨所修饰的词，位于动词，形容词，副词之前，位于名次，代词之前或之后。"

在本题中，only是用来修饰the second one. 理论上讲，C正确。但是，它又紧挨published之前，所以会给人造成一种印象它是在修饰published.

only 修饰动词的例子："He only lent the car." (此处强调，lend rather than sell)

第一道题，only作为强语气词在剧中的位置是不可更改的。你倾向于C同位语平行的问题想必已经想通了。

第二道题，yet表转折，and表顺接。unison与specialized意思对立，所以beating与adopting两个分词结构表伴随动作之间应用yet连接。这道题蛮bt的，需要考虑逻辑意思。

beating in unison yet adopting specialized orientations exclusive of one another是用来说明how heart cells adhere to each other. 因此C是不对的，因为, C将这三个动词看作是并列的成分。

至于A, beating ... 与adopting... 显然是一对有些矛盾的概念，因此，表示对比关系的yet 比表示类同关系的and 就是更好的选择。
