Boldface请教~

frankzhiwei

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, 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.

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



A.The first is the position that the argument seeks to establish; the second reports a discovery that has been used to support a position that the argument opposes.

B.The first is the position that the argument seeks to establish; the second presents an assumption on which the argument relies.

C.The first presents evidence that is used in support of the position that the argument seeks to establish; the second presents an assumption on which the argument relies.

D.The first is an objection raised against a position that the argument opposes; the second is the position that the argument seeks to establish.

E.The first is an objection raised against a position that the argument opposes; the second is evidence that has been used to support that position.

这题选B的原因是？
以及请教怎么做boldface呀，哪位大侠能简单讲讲，正确率太低了！

两句中间以及第二句到结尾没有否定词（最后一句中的but不算）说明全文没有驳斥关系 排除A,D，E 比较B和C
然后看第一句前面，case can be made that 说明B选项的position更好一些

不是虾的飘过

我没有系统地弄过逻辑,这个问题还是留待更多大牛来回答你吧.我是时间来不及了,跑来专门回答别人问题顺便提高自己的.每个人都可以找到自己的方法吧.这类题我不太先看选项,看完题目自己心里先判断一下,选项没必要每个都读得很清楚,用关键词排除一下就可以缩小好几个范围了.

说得好呀~很明了!
可以请问做boldface都是这样读关键字？有时候转折来转折，选项里还有position、argument、assumption、conclusion一起来，头都痛了。怎么应对呢？

不是大侠但回答下你.
我一般题目读两遍.从头到尾之后你会发现头的a strong case can be made that the Greeks actually adopted alphabetic writing at least two centuries earlier的这句话和尾的for about two centuries呼应了,而过程中没有提到什么反对意见,所以CDE都排除了.这是作者的一个观点,相当于先提论点后论证. they would surely ...就是作者的主观判断,不是一个新发现.所以也就排除A了.不求每个字都懂,但大致意思要有个概念.
