还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
D，抽主干Astronomers have uncovered evidence of a star，相比于evidence that，后者在句意上更合适。详细说明了evidence的内容
A，从句中缺少谓语
B correct
without the intended meaning, most splits are actually impossible to decide, since the vast majority of grammar rules just serve to specify the meaning of whatever construction.
2）时态：340,000 years ago = 时态关键词，所以动词 explode 用过去时；
3）修饰语 as bright as the full moon 修饰 star，意思是 ...的星星；
4）doing sth. 放句末，作结果状语，其逻辑主语为 a star exploded into view 340,000 years ago
A：evidence that 引导的从句结构不完整
E，that exploded 和that emitted会误会是在修饰moon
B. 正确，详见“句子结构”分析。
C. Evidence of a star不如evidence that…表达有效。该选项，that成为修饰star的定语从句，整个句子的主结构变成：Astronomers have uncovered evidence of a star――宇航员发现了关于某颗恒星的证据，至于原句要强调的证据的具体内容，被定语从句给“淹没”了;该选项存在平行的两个定语从句：a star that… and that…。第二个定语从句中it多余，that已经指代主语star，it同指代主语star，使这部分从句出现双主语。
D. Of应该为that
E. Of应该为that;that位于moon之后，引导的定语从句错误地修饰了moon。
