※ 引述《amo18 (要打什麽啦)》之铭言： : 不好意思 因为伤咖上不去 : 所以有问题就只能来这里请教了 : 想请问几题CR的问题 : Although fullerenes--spherical molecules made entirely of carbon--were first : found in the laboratory, they have since been found in nature, formed in : fissures of the rare mineral shungite. Since laboratory synthesis of : fullerenes requires distinctive conditions of temperature and pressure, : this discovery should give geologists a test case for evaluating hypotheses : about the state of the Earth's crust at the time these naturally occurring : fullerenes were formed. : Which of the following, if true, most seriously undermines the argument? : (A) Confirming that the shungite genuinely contained fullerenes took careful : experimentation. : (B) Some fullerenes have also been found on the remains of a small meteorite : that collided with a spacecraft. : (C) The mineral shungite itself contains large amounts of carbon, from which : the fullerenes apparently formed. : (D) The naturally occurring fullerenes are arranged in a previously unknown : crystalline structure. : (E) Shungite itself is formed only under distinctive conditions. : 这题找反驳 但我其实看不太出来D和原文的反驳怎麽建立的? : 我选了B 错了 想请教 原文是说:在研究室发现fullerene的形成也许可以提供自然形成fullerene 时候的地壳环境的一个评估(翻的好烂~好难翻) 首先:(A)(C)(E)完全与weaken无关，您排除的是对的 (B)的意思是:fullerene也有在和飞行机相撞的陨石中- 这选项我觉得是无关的，因为外太空怎麽形成fullerene跟提干(地球上怎麽形成) 是无关的。知道外太空怎麽形成我门就不能从实验室的情况推出地壳自然形成的 state(状态)吗? 当然不会。所以(B)似乎是无关。 (D)选项至少比(B)更贴近提干-(D)是说形成的结构是unknow- 所以(B)跟(D)比我会选(D) (虽然CR的答案真的有时候很怪~只能找个比较不烂的) ------------------------- -- --
