※ 引述《tecoteco (teco)》之銘言： 15. Astronomer: Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter's atmosphere in 1994, but they did not show how big those fragments were. In hopes of gaining some indication of the fragments' size, astronomers studied spectrographic analyses of Jupiter's outer atmosphere. These analyses revealed unprecedented traces of sulfur after the fragments' entry. The fragments themselves almost certainly contained no sulfur, but many astronomers believe that the cloud layer below Jupiter's outer atmosphere does contain sulfur. Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter's outer atmosphere without being burned up. In the astronomer's argument, the two portions in boldface play which of the following roles? (A) The first presents a circumstance for which the astronomer offers an explanation; the second is part of that explanation. (B) The first acknowledges a consideration that weighs against the conclusion of the argument; the second is that conclusion. (C) The first acknowledges a consideration that weighs against the conclusion of the argument; the second provides evidence in support of that conclusion. (D) The first provides evidence in support of the conclusion of the argument; the second acknowledges a consideration that weighs against that conclusion. (E) The first is a judgment advanced in support of the conclusion of the argument; the second is that conclusion. 正確答案是E 我看得懂題目 卻不會選答案 麻煩大家幫小弟解答 謝謝!! --------解題思路分隔線------------------------------------------------------ boldface解題思路： (1) 確認態度: 略看句意後發現，兩個boldface間沒有轉折字眼，句意上也無轉折 故排除B, C, D <-注意其中的weigh against (2) 確認功能關鍵字: 第二個boldface的it is likely that，表結果 比較 A (explanation) & E (conclusion)，前者表因，後者表果 故排除A選E Done！ ( 還不知道原題在講什麼東西......-_-||) -- boldface簡單的可以純靠技巧，難的就要拼閱讀實力了..... --
