逻辑:有一道bold face是GWD原题,当时就选错了,今天估计也错了,是宇航员阿sulfur阿什么的。还有一道原题,是两个公司怎么怎么样,since一划线,选都没有overtime工资的那个。 楼主说的是不是这个: 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. Nevertheless, some indication of their size can be inferred from spectrographic analyses of Jupiter’s outer atmosphere. After the fragments’ entry, these analyses revealed unprecedented traces of sulfur. The fragments themselves almost certainly contained no sulfur, but 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 is a claim that the astronomer seeks to show is true; the second acknowledges a consideration that weighs against the truth of that claim. B. The first is a claim that the astronomer seeks to show is true; the second provides evidence in support of the truth of that claim. C. The first and the second are each considerations advanced in support of the conclusion of the argument. D. The first provides evidence in support of the conclusion of the argument; the second is that conclusion. E. The first is a circumstance for which the astronomer seeks to provide an explanation; the second acknowledges a consideration that weighs against the explanation provided by the astronomer. 实战出这么长的CR啊,真是恐怖啊。 能再仔细回忆一下另外一个CR吗?我再查查原文。谢谢啦 |
