Q21:

Although the earliest surviving Greek inscriptions written in an alphabet date from the

eighth century B.C., a strong case can be made that the Greeks actually adopted

alphabetic writing at least two centuries earlier. Significantly, the text of these earliest

surviving Greek inscriptions sometimes runs from right to left and sometimes from

left to right. Now, the Greeks learned alphabetic writing from the Phoenicians, and in

the process they would surely have adopted whatever convention the Phoenicians

were then using with respect to the direction of writing. Originally, Phoenicians

writing ran in either direction, but by the eighth century B.C. it had been consistently

written from right to left for about two centuries.

In the argument given, the two portions in boldface play which of the following roles?

A. The first provides evidence in support of the position that the argument seeks to

establish; the second is that position.

B. The first provides evidence in support of the position that the argument seeks to

establish; the second presents an assumption on which that argument relies.

C. The first is an assumption that the argument concludes is unjustified; the second

presents part of the grounds for that conclusion.

D. The first is evidence that forms the basis for an objection to the position that the

argument seeks to establish; the second is that position.

E. The first is evidence that forms the basis for an objection to the position that the

argument seeks to establish; the second is a judgment that is introduced in order to

call into question the relevance of that evidence.

Answer:b

请NN帮忙解释这道题的解题思路，提干本身的层次该怎样分析，这段话的大概意思也谈谈行吗？谢!!!!!!!!!!!

GWD-7-Q18 & 8-Q21:
Although the earliest surviving Greek inscriptions written in an alphabet date from the eighth century B.C., a strong case can be made that the Greeks actually adopted alphabetic writing at least two centuries earlier.
(the position that the argument seeks to establish，即文章主要结论，虽然现留存最早的希腊文字记录是公元前八世纪，但希腊至少在公元前10世纪就已经形成了字母的文字记录体系...类似意思，不求精确)
Significantly, the text of these earliest surviving Greek inscriptions sometimes runs from right to left and sometimes from left to right.  
(Evidence in support of the position that the argument seeks to establish...支持主要观点的证据...现存的最早希腊文书时而从左往右记录，时而从右往左)
Now, the Greeks learned alphabetic writing from the Phoenicians, and in the process they would surely have adopted whatever convention the Phoenicians were then using with respect to the direction of writing. (presents an assumption on which that argument relies. 假设...因为希腊人是从腓尼基人那里学习了字母记录体系，而且在此过程中希腊人将肯定继承一切腓尼基人的书写习惯，包括他们的记录方向（从左往右or从右往左）...)
Originally, Phoenician writing ran in either direction, but by the eighth century B.C. it had been consistently written from right to left for about two centuries.
（another evidence in support of the main conclusion...事实上腓尼基人在公元前八世纪，就已经固定了从右往左的书写方向 for 2 centuries,且已经固定了两个世纪了...so可以推出希腊人在其固定之前就已经继承了腓尼基人的习惯，也就是至少200年以前了...支持主结论...）

翻译的还蛮丢人的...jj大概理解一下，另外在逻辑区以boldface为关键词搜索，有不少好文章总结了bf题的概念和做题思路，可以看看~

加油！~

谢谢happyfish, 果然是优等生！

我仔细看看题干，发现我对那几个重要的句首副词没搞清意思，有你这样一解释，明白了不少。继续参悟，时间不多了。

thanks!!!
