抱歉，回复有些晚了。when 引导的却是是定语从句哈，其先行词是前面的 a time，when 后面 3 个并列的定语从句，其引导词都是 when，而且其中都有 be 动词，也就是 when the atmosphere was thicker，when the surface was warmer，and when liquid water was widespread. 由于引导词都是 when， 且从句中都有 was，所以后面两句的 when 和 was 都省略了。
老师您好，刚刚做到填空有一句话我不是特别能理解，解析里说这是宾语和宾补使用了倒装的句式， 原句是： They（主语） frequently report（谓语） as factual（宾补） claims（宾语） that historians hotly debate or that are even completely contradicted by reliable primary sources（定语从句？）. 那么正确...... 查看全部
A 选项中的 overturned 与原文的 the conceptual shift away from .... 表达不一致，overturn 说的是“颠覆，推翻”，而后者只是表达观念有所改变，但是否颠覆并未明说。
B 选项中 observations revealed about the composition of the outer planets 这一信息并未在原文中提及，原文中说的是实验室模拟的数据，而且没有说是对 outer planets 的研究。
C 选项与原文表达一致。原文在提到 pristine relics 的时候，使用破折号解释说明了宇航员为什么会有这样的 belief——they remain mostly in the distant Oort cloud，where temperature are close to absolute zero，也即这与宇航员 pristine relics 的想法之间有直接因果关系。

这里原句应该是 The weather is seldom more dramatic than （the weather/it is）when thunderstorms strike. 由于 seldom 是具有否定意义的词，所以前面的主句使用完全倒装句。when thunderstorms strike 的原句应该是 thunderstorms strike in the weather，其中 in the weather 在合并成定语从句时变成了 when，故而 when ... 这个从句是个定语从句哈~~
The rocket site is providing precise measurements of lightning voltages and allowing engineers to check how electrical equipment bears up.这个句子里为啥 how electrical equipment bears up 是宾语从句， to check how electrical equipment bears up.整体不是一个宾语补足语吗？
to check how electrical equipment bears up.整体不是一个宾语补足语 与 how electrical equipment bears up 是宾语从句 并不矛盾哈~~ 在 to check how electrical equipment bears up 这个结构中，check 是及物动词，其后要有自己的宾语，而 how electrical equipment bears up 正好做了 check 的宾语，所以是宾语从句哈~~
