7.  Elizabeth Barber, the author of both Prehistoric Textiles, a comprehensive work on cloth in the early cultures of the Mediterranean, and also of Women's Work, a more general account of early cloth manufacture, is an expert authority on textiles in ancient societies.
【正确答案】 E
【答案解析】 Rhetorical Construction; Idiom; Parallelism
   Using a lot of parenthetical elements, this sentence communicates the main idea that Elizabeth Barber is an authority on textiles in ancient societies. It is the main rhetorical goal of the sentence to position the parenthetical elements so that they do not obscure the main idea. The parenthetical descriptions need to be streamlined enough to be informative, but not too long. In addition, several versions repeat of before the title Women's Work and doing so makes the sentence unparallel; the first of comes before both and so should distribute over both clauses.
   A   The use of also of before Women's Work is redundant and unparallel. It is sufficient to connect the two book titles like this: both X and Y. The meanings of the two nouns expert and authority largely overlap, so there is no need to modify one with the other.
   B   The use of also before Women's Work is redundant. It is sufficient to connect the two book rifles like this: both X and Y. The meanings of the two nouns expert and authority largely overlap, so there is no need to modify one with the other. Finally, the noun authority takes the preposition on, not about.
   C   As in (A), repeating the preposition of before Women's Work makes the sentence unparallel. The noun account takes the preposition of, not about.
   D   As in (A) and (C), repeating the preposition of before Women's Work makes the sentence unparallel. The noun account takes the preposition of, not about. It is redundant to modify authority with expert because they express the same idea. Finally, the noun authority takes the preposition on, not about.
   E   Correct. This version is parallel, uses the most concise structure of the parenthetical descriptions, eschews the redundant modification of authority, and employs the correct prepositions. The correct answer is E.
